Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing, in particular to a food processing device and a food processing method. BACKGROUND

[0002] In food processing, frying, marinating and the like are common cooking methods, usually food raw materials are put into oil liquid / marinating liquid for cooking processing to obtain food finished products. In order to carry out continuous automatic production, a food processing line is usually used, which usually includes a processing tank and a conveying mechanism. The processing tank stores food processing liquid (oil liquid / marinating liquid, etc.), and the material is driven by the conveying mechanism to pass through the processing tank for frying / marinating processing. The processing tank commonly used in the existing food processing line is usually a fixed-volume tank with an open top. The material is stored in a hanging basket, and the conveying mechanism adopts a lifting type conveying mechanism. The path of the conveying mechanism is a concave curve. The hanging basket is first lowered into the processing tank during horizontal travel for processing, and then lifted out of the processing tank after processing is completed. In the existing food processing line, the hanging basket storing the material needs to be lifted by a large amplitude, resulting in a high overall height of the equipment, a large occupied space, a large driving power consumption, low stability, and high equipment operation cost. SUMMARY

[0003] The technical problem to be solved by the present application and the technical task proposed are to improve the prior art and provide a food processing device to solve the problem of the food processing line commonly using a lifting conveying method, which needs to be lifted by a large amplitude, and the equipment occupies a high height and a large volume.

[0004] To solve the above technical problems, the technical solution of the present application is as follows:

[0005] A food processing device, comprising a processing tank, the processing tank is divided into an inlet section, a middle section and an outlet section along the length direction of the processing tank. The inlet of the inlet section is provided with a first gate, the second gate is arranged between the inlet section and the middle section, the third gate is arranged between the middle section and the outlet section, and the outlet of the outlet section is provided with a fourth gate. The inlet section and the outlet section are respectively provided with an openable and closable discharge port, and the processing tank is provided with an injection port for injecting food processing liquid. The food processing device adopts a processing tank divided into multiple sections and provided with gates. By opening and closing the gates, the material can be kept as a whole in the horizontal travel mode through the processing tank when the processing tank contains food processing liquid. The material can be reliably cooked by the food processing liquid during the process of passing through the processing tank. The material does not need to be lifted to the top of the processing tank and then lowered into the processing tank, and the material is lifted out of the processing tank after the food processing is completed. The power consumption required for the material to travel is reduced, the overall height of the equipment is effectively reduced, and the occupied space of the equipment is reduced.

[0006] Further, the discharge port is connected to a food processing liquid circulation system which delivers food processing liquid to the injection port. When the material enters the inlet section or is taken out from the outlet section, the food processing liquid in the inlet section and the outlet section needs to be discharged to ensure the safety and reliability of the material entering and exiting, and the discharged food processing liquid is recycled to reduce processing costs. After the food processing liquid in the inlet section and the outlet section is discharged, the total amount of food processing liquid in the processing tank will decrease, that is, the liquid level of the food processing liquid will decrease, which will affect the normal cooking process. Therefore, food processing liquid is supplemented through the injection port to maintain the stability of the total amount of food processing liquid in the processing tank, ensure the quality of the material cooking in the processing tank, and ensure that the flavor of the processed food can maintain a consistent level.

[0007] Further, the food processing liquid circulation system includes a storage tank for storing food processing liquid, and the storage tank is connected to the injection port through a pipeline assembly. The discharged food processing liquid from the inlet section and the outlet section can be temporarily stored in the storage tank, and the food processing liquid can be supplemented into the processing tank when needed, ensuring stable operation of the processing tank.

[0008] Further, a heating assembly is provided on the storage tank. Halogenation, frying and other cooking methods are usually hot processing methods. The food processing liquid is heated by the heating assembly to ensure the stability of the cooking process.

[0009] Further, a filtering device is provided in the food processing liquid circulation system. During the cooking process of the material through the food processing liquid, material residues may enter the food processing liquid. Material residues can cause pipeline blockage and affect the quality and flavor of the food processing liquid. Therefore, the discharged food processing liquid from the inlet section and the outlet section is filtered to remove the material residues, ensuring the quality and flavor of the food processing liquid and ensuring the consistency of the flavor and quality of the food processing.

[0010] Further, it also includes a carrier for loading the material in the carrier to travel through the processing tank. Large-sized materials can be sent into the processing tank as a single conveying unit. The material travels along the processing tank for cooking. For small-sized materials, a carrier is provided for batch conveying of the material to improve processing efficiency and productivity. A certain amount of material is loaded in the carrier, and then the carrier is sent into the processing tank as a conveying unit. The carrier travels along the processing tank to cook the material.

[0011] Further, the carrier comprises a plurality of layers arranged in a stack for storing the materials. When the loading amount of the materials is large, the materials stacked at the bottom are prone to be deformed or damaged under pressure. The storage layers are used to store the materials in layers, which can improve the loading amount of the materials in a single conveying unit while effectively ensuring the integrity of the materials, thereby improving the production capacity.

[0012] Further, the conveying mechanism is arranged along the length direction of the processing groove to convey the materials along the processing groove. The automation degree is improved, and the conveying mechanism can convey the materials along the transverse direction to make the materials move through the processing groove without lifting the materials greatly, thereby reducing the height of the whole device and the occupied space.

[0013] Further, the feeding mechanism is arranged at the entrance of the inlet section to feed the materials into the inlet section.

[0014] The taking-out mechanism is arranged at the exit of the outlet section to take out the materials from the outlet section.

[0015] The automation degree is improved, and the materials can be fed and taken out without manual operation, thereby improving the processing efficiency and reliability.

[0016] Further, the conveying mechanism comprises a first conveying section, a second conveying section and a third conveying section. The first conveying section is arranged in the inlet section, the second conveying section is arranged in the middle section, and the third conveying section is arranged in the outlet section. The conveying paths of the first, second and third conveying sections are arranged along the length direction of the processing groove, and the first, second and third conveying sections are connected to convey the materials.

[0017] Alternatively, the conveying mechanism comprises a hoisting conveying line arranged above the processing groove. The conveying path of the hoisting conveying line is arranged along the length direction of the processing groove, and the materials are hoisted on the hoisting conveying line to move along the processing groove.

[0018] The structure is simple and easy to implement. The conveying mechanism only conveys the materials along the transverse direction, and the gates in the processing groove only need to be opened and closed in coordination, thereby reducing the occupied space and effectively reducing the height of the whole device.

[0019] Further, the conveying mechanism comprises a lifting assembly, a bracket and a power assembly, the lifting assembly and the power assembly are arranged outside the processing tank, the lifting assembly drives the bracket to move up and down, the power assembly drives the bracket to move back and forth along the length direction of the processing tank, when the lifting assembly is lowered to the low position, the bracket is separated from the materials in the processing tank, when the lifting assembly is raised to the high position, the bracket lifts the materials to the suspended state so that the materials move with the bracket. The bracket performs the circulation action under the driving of the lifting assembly and the power assembly to drive the materials to move in the processing tank along the transverse direction intermittently, the lifting assembly only needs to perform the small amplitude lifting action, only needs to lift the materials to the suspended state which is not in direct contact with the food processing liquid in the processing tank, and does not need to lift the materials completely out of the liquid surface of the food processing liquid in the processing tank, so that a large height movement space is not needed, the overall height of the equipment can be effectively avoided to be too high, the compactness of the structure is improved, the overall volume of the equipment is reduced, and the lifting assembly and the power assembly of the conveying mechanism are arranged outside the processing tank, only the bracket is in direct or indirect contact with the materials, that is, only the bracket can enter the food processing liquid, so that there is no mutual cooperation movement component in the food processing liquid of the processing tank, even if the lifting assembly and the power assembly are worn, the residue generated by mechanical wear will not enter the food processing liquid, the residue pollutes the food processing liquid and the materials, the sanitary safety of the food processing liquid is effectively ensured, and the processing quality of the materials is ensured.

[0020] Further, the power assembly is in transmission connection with the bracket, a pulley is arranged on the lifting assembly to slide with the bracket along the length direction of the processing tank, or a pulley is arranged on the bracket to slide with the lifting assembly along the length direction of the processing tank. The cooperation mode of rolling contact reduces the resistance, so that the power assembly can more easily drive the bracket and the materials to move, the driving power consumption is reduced, the wear is reduced, and the service life is prolonged.

[0021] Further, the bracket covers the entry section, the middle section and the exit section to drive all the materials arranged along the length direction of the processing tank to move synchronously. The materials in the processing tank are kept synchronous when moving, the condition that the materials collide with each other or the latter materials do not follow is avoided, and it is ensured that all the materials can orderly move along the processing tank.

[0022] Further, the lifting assembly comprises a plurality of lifting units arranged at intervals along the length direction of the processing tank. The stability of the lifting assembly lifting the bracket is improved, it is ensured that the materials can orderly and stably move along the processing tank, the weight of all the materials in the processing tank is distributed on each lifting unit, the load of each lifting unit is small, the use stability is better, and the service life is long.

[0023] A food processing method using the food processing device, comprising the following steps:

[0024] opening the first gate, feeding the material into the inlet section through the inlet;

[0025] closing the first gate and the fourth gate, and then opening the second gate and the third gate to supplement the food processing liquid into the processing tank;

[0026] making the material travel along the processing tank;

[0027] when the material enters the outlet section, closing the second gate and the third gate, emptying the food processing liquid in the inlet section and the outlet section, and then opening the fourth gate to take out the material from the outlet section.

[0028] The food processing method can feed, pass and take out the material in the processing tank in a way that the material keeps traveling horizontally as a whole, which can guarantee good cooking processing without making the material make large lifting movements, reduce the overall height of the equipment, guarantee enough cooking processing time for the material in the processing tank, guarantee the cooking processing quality, and ensure the safety and reliability of production and processing.

[0029] Further, the food processing liquid discharged from the inlet section and the outlet section is returned to the processing tank. Recycling the discharged food processing liquid can reduce processing costs, maintain the total amount of food processing liquid in the processing tank stable, and guarantee the stability of cooking processing.

[0030] Further, the food processing liquid discharged from the inlet section and the outlet section is filtered and then returned to the processing tank. In the process of cooking the material through the food processing liquid, the material residue may enter the food processing liquid, which may affect the quality of the food processing liquid after a long time, and then affect the taste and quality of the processed food product. Therefore, the food processing liquid in the inlet section and the outlet section is discharged, and the discharged food processing liquid is filtered to improve the overall recycling efficiency of the food processing liquid.

[0031] A food processing method using the food processing device, comprising the steps of:

[0032] opening the first gate, feeding the material into the inlet section through the inlet;

[0033] closing the first gate and the fourth gate, and then opening the second gate and the third gate to supplement the food processing liquid into the processing tank;

[0034] When the lifting component is raised to the high position, the power component drives the bracket and material to move a preset distance toward the outlet section. Then the lifting component is lowered to the low position, and the power component drives the bracket to return to the inlet section a preset distance. This process is repeated to make the material move along the processing groove.

[0035] After the material enters the outlet section, the second and third gates are closed to drain the food processing liquid from the inlet and outlet sections. Then, the fourth gate is opened to remove the material from the outlet section.

[0036] The food processing method described in this invention allows the material to be fed into, through, and removed from the processing tank while maintaining a horizontal movement, even when there is food processing liquid in the tank, by opening and closing a gate. This ensures proper cooking and processing without causing significant lifting or lowering of the material, thus reducing the overall height of the equipment.

[0037] Compared with the prior art, the advantages of the present invention are as follows:

[0038] The food processing apparatus and method described in this invention employ a segmented processing tank. By opening and closing the gate, the material can be kept moving laterally through the processing tank even when there is food processing liquid inside. This ensures good cooking and processing while avoiding large-scale lifting and moving of the material, effectively reducing the overall height of the equipment, resulting in a compact structure and reduced equipment volume.

DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0058] The food processing device and the food processing method disclosed by the embodiment of the application have a compact structure, the material travels in a horizontal manner as a whole, does not need to be lifted greatly, can effectively reduce the overall height and volume of the equipment, has high reliability and good stability, and is beneficial to improving the processing yield.

[0059] Embodiment one

[0060] As shown in Figure 1 and Figure 2 , a food processing device mainly comprises a processing tank 1, food processing liquid is added in the processing tank 1, the food processing liquid can be brine, oil liquid and the like, and cooking processing such as marinating and frying can be performed according to needs, the processing tank 1 is a tank body extending along the horizontal direction in the length direction as a whole, preferably, the processing tank 1 is a straight tank body, of course, it can also be a curved tank body, which does not affect the function implementation of the processing tank 1, the processing tank 1 is divided into an inlet section 11, a middle section 12 and an outlet section 13 along the length direction thereof, a first gate 14 is arranged at the inlet of the inlet section 11, a second gate 15 is arranged between the inlet section 11 and the middle section 12, a third gate 16 is arranged between the middle section 12 and the outlet section 13, a fourth gate 17 is arranged at the outlet of the outlet section 13, the inlet section 11 and the outlet section 13 are respectively provided with an openable and closable discharge port 18, and an injection port 19 for injecting food processing liquid is arranged on the processing tank 1. The inlet and the outlet can be arranged at the end side in the length direction of the processing tank 1, so that in the state that the first gate 14, the second gate 15, the third gate 16 and the fourth gate 17 are all opened, the processing tank 1 as a whole is a through tank with an open end, the cross section of which is substantially U-shaped, and a path is formed from the inlet to the outlet, in other words, the material to be processed can enter the processing tank 1 from the inlet, then the material travels along the processing tank 1, and finally the material can be taken out to the outside from the outlet of the processing tank 1, the path of the material is a whole path along the horizontal path, and the material does not need to be lifted greatly, so that a large height activity space is not needed, thereby effectively reducing the overall height of the equipment and reducing the space occupied by the equipment. Of course, the inlet and the outlet can not be arranged at the end side in the length direction of the processing tank 1, as shown in Figure 3 , the inlet can be arranged on the side wall of the inlet section 11, and the outlet can be arranged on the side wall of the outlet section 13, and similarly, a whole path is formed from the inlet to the outlet along the horizontal path, and the material does not need to be lifted greatly during the traveling process. As shown in Figure 1As shown, the first gate 14, the second gate 15, the third gate 16, and the fourth gate 17 are gates that move up and down. That is, the gates are in the open state when they rise and in the closed state when they fall. This type of gate will occupy more height space relative to the processing tank 1 body. Of course, the first gate 14, the second gate 15, the third gate 16, and the fourth gate 17 can also be gates that open and close laterally. That is, the gates move laterally to open and close. This method can reduce the height, while the lateral width at the gate location is increased to a certain extent.

[0061] During food cooking and processing, food processing liquid is added to the processing tank 1 of the aforementioned food processing apparatus. To ensure the cooking and processing effect, the material usually needs to be completely submerged in the food processing liquid for cooking. For the material to pass through the processing tank 1 without significant vertical movement, each gate needs to be opened. To ensure that the material passes through the processing tank 1 in a lateral manner while the processing liquid is present, the opening and closing of each gate needs to be coordinated. Specifically, the food processing method using the aforementioned food processing apparatus includes the following steps:

[0062] like Figure 4 As shown in (a), with the second gate 15 and the third gate 16 closed and the inlet section 11 and outlet section 13 emptied of food processing liquid, the first gate 14 is opened to send the material into the inlet section 11. At this time, since the second gate 15 and the third gate 16 are closed, the middle section 12 is a complete container for the food processing liquid. The food processing liquid is safely and leak-free stored in the middle section 12. The inlet section 11 and outlet section 13 have been emptied of the food processing liquid through the vent 18. Therefore, when the first gate 14 is opened, the food processing liquid will not leak out from the inlet, ensuring the safety and reliability of sending the material into the middle section 11 and preventing the food processing liquid from leaking out from the inlet and polluting the environment.

[0063] like Figure 4-(b) as shown, after the material enters into the inlet section 11, the first gate 14 and the fourth gate 17 are closed, at this time the whole processing tank 1 constitutes a complete container, the food processing liquid cannot flow out from the inlet and the outlet, then the second gate 15 and the third gate 16 are opened, at this time the inlet section 11 and the outlet section 13 are communicated with the middle section 12, the food processing liquid stored in the middle section 12 will flow into the inlet section 11 and the outlet section 13, the volume of the whole processing tank 1 is larger than the volume of the middle section 12, so that the liquid level of the food processing liquid will be lowered, in order to guarantee that the material can be reliably cooked, the food processing liquid is supplemented into the processing tank 1 through the injection inlet 19, the injection inlet 19 is preferably arranged at the position of the middle section 12, so that the liquid level of the food processing liquid can be maintained at a relatively stable height, thereby ensuring that the material can be fully immersed in the food processing liquid, and ensuring that the material can be fully cooked, the food processing liquid in the inlet section 11 and the outlet section 13 needs to be emptied every time the material is sent into the inlet section 11, so that the food processing liquid in the processing tank 1 is periodically continuously reduced, so it is also necessary to periodically supplement the food processing liquid into the processing tank 1 to maintain the total amount of food processing liquid in a stable state, thereby guaranteeing the stability of the cooking process.

[0064] As Figure 4 -(c) as shown, in the state that the first gate 14 and the fourth gate 17 are closed and the second gate 15 and the third gate 16 are opened in the previous step, a passage is formed in the processing tank 1 from the inlet section 11 to the outlet section 13, at this time the material can freely move in the processing tank 1, thereby making the material travel along the processing tank 1 and making the material move into the outlet section 13. In the process of material movement, the food processing liquid continuously cooks the material, and the cooking process is basically completed when the material enters the outlet section 13. The cooking time is matched with the movement rate of the material in the processing tank 1, and is set according to the processing needs. The travel of the material along the processing tank 1 can be manual operation, that is, manually pushing the material to travel along the processing tank 1, for example, manually operating a tool such as a push rod or a push plate to extend into the food processing liquid in the processing tank 1, and then manually pushing the material to move, or a part of the material extends out of the food processing liquid for manual pushing of the material, or a pushing member is connected to the material and extends out of the food processing liquid for manual pushing of the material. Of course, in order to improve the degree of automation, a conveying mechanism matched with the processing tank 1 can be arranged, which is arranged along the length direction of the processing tank 1 to drive the material to travel along the processing tank 1. The conveying mechanism can adopt various types, which can drive the material to travel along the transverse direction without the need to greatly lift the material in height, so that the structure of the conveying mechanism is more compact, without the need for a large height activity space, so that the overall height of the food processing device is lower, occupying less space, which is beneficial to the space layout of the production line.

[0065] As Figure 4 (d) shown, when the material enters the out section 13, the cooking process has been basically completed, then the second gate 15 and the third gate 16 are closed, at this time the middle section 12 becomes a complete container again, the food processing liquid can be safely stored in the middle section 12 without leakage, at this time the in section 11 and the out section 13 still have food processing liquid, the first gate 14 and the fourth gate 17 cannot be directly opened, otherwise the food processing liquid will flow out from the inlet and the outlet, which has safety risks and will pollute the environment, therefore, in the state that the material enters the out section 13 and the second gate 15 and the third gate 16 have been closed, the food processing liquid in the in section 11 and the out section 13 is discharged through the discharge port 18. Then as Figure 4 (e) shown, the fourth gate 17 can be safely opened to take out the material whose cooking process has been completed from the out section 13, and the process of discharging the food processing liquid in the out section 13 is also the draining process of the material whose cooking process has been completed, which avoids taking out the material with too much food processing liquid, avoids the waste of food processing liquid, and is also beneficial to the better subsequent processing of the material.

[0066] The lengths of the in section 11, the middle section 12 and the out section 13 can be specifically set according to needs, the lengths of the in section 11 and the out section 13 can be lengths capable of simultaneously accommodating multiple conveying units arranged along the length direction of the processing groove 1, or can be lengths capable of only accommodating one material unit, the conveying unit refers to the material, the length of the middle section 12 can simultaneously accommodate several conveying units arranged along the length direction of the processing groove 1, and is specifically set according to the cooking processing time and the material advancing speed.

[0067] The above-mentioned steps of the food processing method are the main steps performed when the food processing device is in operation, some of which are not in a specific order, and the specific steps are performed according to the specific position and number of the conveying units in the processing tank 1, some of which are performed simultaneously in certain conditions, and some of which are performed separately in other conditions. When the food processing device is just started, the first conveying unit is sent into the inlet section 11 through the inlet in the state that the second gate 15 and the third gate 16 are closed and the inlet section 11 and the outlet section 13 are emptied of the food processing liquid, the first gate 14 is opened, the first gate 14 and the fourth gate 17 are closed, then the second gate 15 and the third gate 16 are opened, the food processing liquid is supplemented into the processing tank 1, at this time the cooking processing of the first conveying unit has begun, the first conveying unit is conveyed along the processing tank 1, when the first conveying unit passes through the second gate 15 into the middle section 12, the second gate 15 and the third gate 16 are closed, then the food processing liquid in the inlet section 11 is emptied, then the first gate 14 is opened, the second conveying unit is sent into the inlet section 11 through the inlet, then the first gate 14 and the fourth gate 17 are closed, then the second gate 15 and the third gate 16 are opened, the food processing liquid is supplemented into the processing tank 1, at this time the cooking processing of the first conveying unit and the second conveying unit is performed, the first conveying unit and the second conveying unit are conveyed along the processing tank 1 synchronously, when the second conveying unit passes through the second gate 15 into the middle section 12, the second gate 15 and the third gate 16 are closed, then the food processing liquid in the inlet section 11 is emptied, then the first gate 14 is opened, the third conveying unit is sent into the inlet section 11 through the inlet, and so on until the middle section 12 is arranged with conveying units along the length direction of the processing tank 1, that is, the first conveying unit just reaches the position near the third gate 16 (there is no step of taking out the conveying unit from the outlet section 13 in the above process);

[0068] Then, continue in the state that the second gate 15 and the third gate 16 are closed and the entry section 11 and the exit section 13 are emptied of the food processing liquid, open the first gate 14, and pass the Nth conveying unit into the entry section 11 through the entrance (assuming that the length of the middle section 12 can accommodate 3 conveying units arranged along the length direction of the processing tank 1 at the same time, then N is 4); then close the first gate 14 and the fourth gate 17, and then open the second gate 15 and the third gate 16, and supplement the food processing liquid into the processing tank 1; all the conveying units in the processing tank 1 are synchronized to travel along the processing tank 1, the first conveying unit passes the third gate 16 and enters the exit section 13, and the Nth conveying unit passes the second gate 15 and enters the middle section 12; then close the second gate 15 and the third gate 16, at this time, the middle section 12 is full of conveying units, and then empty the food processing liquid in the entry section 11 and the exit section 13, and then open the first gate 14 and the fourth gate 17, and pass the next conveying unit into the entry section 11 through the entrance, and at the same time, take out the first conveying unit from the exit section 13, and so on to continuously pass the conveying units into the processing tank 1 and take out the cooked and processed conveying units from the processing tank 1.

[0069] For some large-size materials, such as whole chickens, ducks, pigs, etc., a single material can constitute a conveying unit, that is, a single material is sequentially passed into the processing tank 1 for cooking and processing, and the cooked and processed material is sequentially taken out from the processing tank 1. For some small-size materials, such as dried bean curd, dried egg, chicken feet, etc., the efficiency of cooking and processing a single material as a conveying unit is too low, as shown in FIG. 1, a carrier 2 can be provided to load a batch of materials, and the carrier 2 loaded with the batch of materials constitutes a conveying unit, which can effectively improve the processing efficiency and yield. Figure 5 Preferably, the carrier 2 includes a plurality of storage layers 21 arranged in layers for loading materials. When the loading amount of materials is large, the materials stacked at the bottom are prone to compression deformation or damage. Therefore, the storage layers can be used to load materials in layers, which can effectively ensure the integrity of the materials while increasing the loading amount of materials in a single conveying unit, thereby effectively improving the production capacity. In order to enable the materials to be in full contact with the food processing liquid, the carrier 2 is preferably in the form of a frame basket structure, and the food processing liquid can fully contact the materials through the holes of the frame basket, thereby ensuring the sufficiency of the cooking and processing.

[0070] Further, when new conveying units are fed into the processing tank 1 and the processing completed conveying units are taken out of the processing tank 1, the food processing liquid in the in-segment 11 and the out-segment 13 needs to be drained through the drain port 18. In theory, the food processing liquid drained from the in-segment 11 and the out-segment 13 can be directly discarded, and each time the food processing liquid fed into the processing tank 1 is fresh food processing liquid. However, this way is relatively high in cost. Therefore, the food processing liquid drained from the in-segment 11 and the out-segment 13 is recycled and returned into the processing tank 1, so as to effectively maintain the stability of the weight of the food processing liquid in the processing tank 1 and is relatively low in cost. Meanwhile, when the food processing liquid cooks the material, material residues peeled off from the material will inevitably enter the food processing liquid. After long time processing, the concentration of the material residues will be high, which will seriously affect the quality of the food processing liquid, affect the quality and flavor of the food processing, and cause blockage of the pipeline. Therefore, the food processing liquid drained from the in-segment 11 and the out-segment 13 is filtered and then returned into the processing tank 1, so as to guarantee the quality of the food processing.

[0071] Specifically, as shown in Figure 6 the drain port 18 is connected to a food processing liquid circulating system 3. The food processing liquid circulating system 3 delivers the food processing liquid to the injection port 19, i.e., the food processing liquid drained from the in-segment 11 and the out-segment 13 is recycled and delivered to the injection port 19 through the food processing liquid circulating system 3 to be added into the processing tank 1. Of course, the food processing liquid circulating system 3 also comprises a fresh food processing liquid making device or a fresh food processing liquid injection device, so that fresh food processing liquid can be added into the processing tank 1 according to the specific processing condition, so as to guarantee the stable and consistent flavor of the processed food products. The food processing liquid circulating system 3 can also be provided with a filtering device to filter the drained food processing liquid and remove the residues in the food processing liquid. The filtering device can be a centrifugal separation filtering device, which is high in efficiency and good in filtering effect, can guarantee the purity of the obtained food processing liquid, and further guarantee the stable food processing quality.

[0072] In an embodiment, as shown in Figure 7 and Figure 8As shown, the food processing liquid circulating system 3 is a simple circulating system, which comprises a storage tank 31 for storing food processing liquid, the storage tank 31 is connected to the injection inlet 19 through a pipeline assembly, a delivery pump is arranged on the pipeline assembly, a heating assembly 32 is arranged on the storage tank 31, brining, frying and other cooking methods are usually hot processing, the food processing liquid is heated by the heating assembly to ensure stable cooking processing. The drain port 18 is connected to the storage tank 31 through a pipeline, a valve is arranged on the pipeline, the storage tank 31 can be directly arranged at the bottom of the processing tank 1, when it is needed to empty the food processing liquid in the inlet section 11 and the outlet section 13, the valve is opened, the food processing liquid in the inlet section 11 and the outlet section 13 is automatically and quickly discharged into the storage tank 31 for temporary storage, further, the storage tank 31 is provided with two, the drain port 18 of the inlet section 11 is connected to one storage tank 31, the drain port 18 of the outlet section 13 is connected to the other storage tank 31, the emptying of the inlet section 11 and the outlet section 13 does not interfere with each other, the injection inlet 19 is specifically arranged at the bottom of the middle section 12, the food processing liquid is returned to the processing tank 1 by injecting into the middle section 12, the total amount of food processing liquid in the processing tank 1 is relatively stable, and then the material is stably and reliably cooked.

[0073] In an embodiment, as shown in Figure 9 and Figure 10 In order to improve the degree of automation, the food processing device is also provided with a conveying mechanism, which is arranged along the length direction of the processing tank 1 to drive the material to move along the processing tank 1. In this embodiment, the conveying mechanism specifically comprises a lifting assembly 41, a bracket 43 and a power assembly 42, the lifting assembly 41 and the power assembly 42 are arranged outside the processing tank 1, the lifting assembly 41 drives the bracket 43 to lift and lower, and the power assembly 42 drives the bracket 43 to reciprocate along the length direction of the processing tank 1, when the lifting assembly 41 is lowered to the low position, the bracket 43 is separated from the material in the processing tank 1, when the lifting assembly 41 is raised to the high position, the bracket 43 lifts the material to the suspended state to make the material move with the bracket 43, the material here refers to the conveying unit, when the bracket 43 is separated from the carrier 2 in the processing tank 1 when the lifting assembly 41 is lowered to the low position, the carrier 2 is directly carried by the inner wall of the processing tank 1 at this time, and when the lifting assembly 41 is raised to the high position, the bracket 43 lifts the carrier 2 to the suspended state to make the carrier 2 move with the bracket 43.

[0074] More specifically, as shown in Figure 11 and Figure 12As shown, the power assembly 42 is in transmission connection with the bracket 43, and the power assembly 42 specifically includes a linear reciprocating mechanism and a connecting rod, the linear reciprocating mechanism can be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc., one end of the connecting rod is in transmission connection with the linear reciprocating mechanism, and the other end is in transmission connection with the bracket 43, and the jacking assembly 41 is provided with a pulley 411 to slide fit with the bracket 43 in the length direction of the processing tank 1, so that the bracket 43 can slide along the length direction of the processing tank 1 under the drive of the power assembly 42 relative to the jacking assembly 41, and at the same time the jacking assembly 41 also drives the bracket 43 to lift to switch between the low position and the high position, the activities of the bracket 43 in the two movement dimensions do not interfere with each other, and the cooperation mode of rolling contact is adopted to reduce the resistance, so that the power assembly can more easily drive the bracket and the material to move, reduce the driving power consumption, reduce the wear and prolong the service life. In addition, the bracket 43 can also be provided with a pulley 411 to slide fit with the jacking assembly 41 in the length direction of the processing tank 1; it can also be that the power assembly 42 is in transmission connection with the jacking assembly 41, and then the jacking assembly 41 is in transmission connection with the bracket 43, and the same can realize the activities of the bracket 43 in the two dimensional directions.

[0075] Further, the jacking assembly 41 is provided with a group on both sides of the processing tank 1, the jacking assembly 41 includes a plurality of jacking units arranged at intervals along the length direction of the processing tank 1, which improves the stability of the jacking assembly 41 lifting the bracket 43, and ensures that the material can orderly and stably travel along the processing tank 1, and the weight of all materials in the processing tank 1 is distributed on each jacking unit, and the load of each jacking unit is small, specifically, the jacking unit can adopt a hydraulic cylinder, which has strong power, good stability and long service life.

[0076] More specifically, the carrier 43 covers the entry section 11, the middle section 12 and the exit section 13 to drive all the conveyors arranged along the length of the processing tank 1 to move synchronously, i.e. to keep all the conveyors in the processing tank 1 moving synchronously, to avoid the situation that the conveyors hit each other or the situation that the conveyors behind do not keep up, and to ensure that all the conveyors can orderly travel along the processing tank 1. When the food processing device is in the continuous working cycle stage, the middle section 12 is filled with the conveyors arranged along the length of the processing tank 1, new conveyors are fed into the entry section 11, and the conveyors in the exit section 13 have been taken out, so when the conveying mechanism is working, it simultaneously drives all the conveyors in the middle section 12 and the conveyors in the entry section 11 to move synchronously towards the exit section 13 side, and finally reaches the state that the first conveyor in the middle section 12 close to the exit section 13 completely enters the exit section 13, and the conveyors in the entry section 11 completely enter the middle section 12, then the second gate 15 and the third gate 16 can be closed, then the food processing liquid in the entry section 11 and the exit section 13 is emptied, then the first gate 14 is opened to put in new conveyors, and the fourth gate 17 is opened to take out the conveyors whose cooking process is completed.

[0077] Further, the power assembly 42 of the conveying mechanism drives the bracket 43 to move in the length direction of the processing tank 1, preferably small amplitude movement, that is, the first conveying unit on the side close to the out section 13 in the middle section 12 is not directly moved into the out section 13 at one time, but the conveying mechanism needs to circulate and act several times to completely move the first conveying unit on the side close to the out section 13 in the middle section 12 into the out section 13. The working steps of the conveying mechanism in the embodiment are as follows: first, the jacking assembly 41 is in the low position, at this time, the bracket 43 is separated from the conveying unit (that is, the material or the carrier loaded with the material) in the processing tank 1; then the jacking assembly 41 is raised to the high position, the jacking assembly 41 lifts the bracket 43 to make the bracket contact and combine with the conveying unit, and then the bracket 43 lifts the conveying unit to the suspended state, in this process, the jacking assembly 41 does not need to be raised and lowered by a large amplitude, but only needs to be raised by a small amplitude to remove the state that the conveying unit is supported on the inner wall of the processing tank 1, so that the conveying mechanism can normally work without a large height of activity space, the structure is compact, and the overall volume of the food processing device is reduced; then the power assembly 42 drives the bracket 43 and the conveying unit to move a preset distance along the length direction of the processing tank 1 towards the out section 13, the preset distance is a small distance along the length direction of the processing tank 1, which is specifically set according to the need, and the specific value of the preset distance can be flexibly adjusted in real time by the power assembly 42 according to the need to control the processing time of the material unit in the processing tank 1; then the jacking assembly 41 is lowered to the low position, so that the bracket 43 and the conveying unit are separated again; then the power assembly 42 drives the bracket 43 to return a preset distance along the length direction of the processing tank 1 towards the in section 11, since the bracket 43 and the conveying unit have been separated, the bracket 43 will not drive the conveying unit to move reversely when reversely moving, and the conveying unit will remain in the original position. The above working steps constitute a cycle step unit, since the preset distance is a short distance in a single cycle step unit, the cycle step unit needs to be repeatedly executed several times to completely move the first conveying unit on the side close to the out section 13 in the middle section 12 into the out section 13, the size of the preset distance and the number of cycles are determined by the cooking processing time required, so that the conveying mechanism drives the conveying unit to intermittently move along the length direction of the processing tank 1 towards the side where the out section 13 is located, and the height of the conveying unit only changes by a small amplitude during the movement, and then the conveying unit as a whole can be regarded as intermittently moving in the transverse direction.

[0078] In the embodiment, the lifting assembly 41 and the power assembly 42 are arranged outside the processing tank 1, and the conveying unit needs to enter the food processing liquid in the processing tank 1 for cooking processing. The lifting assembly 41 and the power assembly 42 indirectly drive the conveying unit to move through the bracket 43. The moving parts of the lifting assembly 41 and the power assembly 42, which are subject to mechanical wear, are completely separated from the food processing liquid, so that even if the lifting assembly 41 and the power assembly 42 are subject to mechanical wear, the residues generated thereby will not enter the food processing liquid, thereby ensuring the hygiene and safety of food processing. The conveying mechanism in the embodiment drives the conveying unit to move along the processing tank 1 through the bracket 43. The bracket 43 can be completely outside the food processing liquid in the processing tank 1, and a part of the material extends out of the food processing liquid, so that the bracket 43 cooperates with the part of the material extending out of the food processing liquid to drive the material to move. The pushing member can be arranged on the material, and the pushing member extends out of the food processing liquid to cooperate with the bracket 43 to drive the material to move. When the material is loaded in the carrier 2 to form the conveying unit, a part of the carrier 2 can extend out of the food processing liquid to cooperate with the bracket 43 to drive the material to move. Alternatively, the bracket 43 extends into the processing tank 1 to form a lifting part 431, and the lifting part 431 cooperates with the conveying unit to drive the material to move. Specifically, as shown in Figure 12 the lifting part 431 is lower than the bottom of the carrier 2 when the lifting assembly 41 is lowered to the low position; and the lifting part 431 lifts the bottom of the carrier 2 to lift the carrier 2 to a suspended state when the lifting assembly 41 is raised to the high position. The bracket 43 supports and lifts the carrier 2 from the bottom of the carrier 2 through the lifting part 431, and the support stability of the carrier 2 is good. When the bracket 43 drives the carrier 2 to move, the bracket 43 and the carrier 2 are subject to static friction, so that mechanical wear does not occur. The carrier 2 loaded with the material is in a suspended state without contacting the processing tank 1, so that the carrier 2 and the inner wall of the processing tank 1 are not subject to sliding friction, and mechanical wear residues do not occur, and the mechanical wear residues will not enter the food processing liquid, thereby ensuring the hygiene and safety of food processing.

[0079] Further, since the bracket 43 supports and lifts the carrier 2 from the bottom of the carrier 2 through the lifting part 431, the lifting part 431 needs to move up and down relative to the carrier 2. The lifting part 431 separates from the carrier 2 when the lifting part 431 is lowered, and the lifting part 431 supports the bottom of the carrier 2 to lift the carrier 2 when the lifting part 431 is raised. Therefore, as shown in Figure 8As shown, a cushion 110 can be arranged at the bottom of the processing tank 1 to support the carrier 2, and the cushion 110 can reserve a space for the lifting part 431 to move, or the bottom of the carrier 2 itself can be arranged with a step to reserve a space for the lifting part 431 to move. Further, the bracket 43 can cooperate with other parts of the carrier 2, for example, a supporting part arranged at the top of the carrier 2 cooperates with the bracket 43, and the carrier 2 is lifted by the supporting part when the bracket 43 is lifted.

[0080] In an embodiment, as shown in Figure 8 and Figure 10 When the first gate 14 and the fourth gate 17 are opened to put in new conveying units and take out the conveying units after processing, the second gate 15 and the third gate 16 are in a closed state, so that the conveying mechanism cannot operate at this time, and the conveying units after cooking processing in the out section 13 cannot be directly sent out of the outlet by the conveying mechanism. In order to facilitate the removal of materials, the bottom of the out section 13 is provided with a roller 111 for supporting the carrier 2, so that the carrier 2 loaded with materials can be more easily slid out. Similarly, the bottom of the in section 11 is provided with a roller 111 for supporting the carrier 2, so that the carrier 2 loaded with materials can be more easily slid into the in section 11.

[0081] Further, as shown in Figure 13 and Figure 14 The food processing device further comprises a feeding mechanism 51 arranged at the entrance of the in section 11 to feed materials into the in section 11, and a taking-out mechanism 52 arranged at the outlet of the out section 13 to take out materials from the out section 13. This can better improve the degree of automation, and materials can be fed and taken out without manual operation, thereby improving processing efficiency and reliability. Specifically, the feeding mechanism 51 and the taking-out mechanism 52 respectively comprise a moving assembly 511 and a conveying line 512. The moving assembly 511 of the feeding mechanism moves to push the carrier 2 from the conveying line 512 of the feeding mechanism 51 into the in section 11, and the moving assembly 511 of the taking-out mechanism 52 moves to pull the carrier 2 in the out section 13 out of the conveying line 512 of the taking-out mechanism 52. The conveying line 512 specifically comprises two parallel conveying chains to carry the bottom of the conveying unit, and the moving assembly 511 is located between the two conveying chains and reciprocally moves along the conveying direction of the conveying chains to push the conveying unit.

[0082] When the food processing device adopts the above conveying mechanism to process food, the steps of the food processing method specifically include:

[0083] With the second gate 15 and the third gate 16 closed and the inlet section 11 and the outlet section 13 emptied of food processing liquid, the first gate 14 is opened to send the conveying unit into the inlet section 11 through the inlet;

[0084] Close the first gate 14 and the fourth gate 17, then open the second gate 15 and the third gate 16 to add food processing liquid into the processing tank 1;

[0085] The conveying mechanism drives the conveying unit to move along the processing groove 1. Specifically, the lifting component 41 is raised to the high position. At this time, the bracket 43 is engaged with the conveying unit. The power component 42 drives the bracket 43 and the conveying unit to move together toward the exit section 13 by a preset distance. Then the lifting component 41 is lowered to the low position, and the bracket 43 is separated from the conveying unit. The power component 42 then drives the bracket 43 back toward the inlet section 11 by a preset distance. At this time, since the bracket 43 has been separated from the conveying unit, the conveying unit will remain in the current position and will not move back with the bracket 43. This process can be repeated to make the conveying unit move along the processing groove 1.

[0086] After the material enters the outlet section 13, the second gate 15 and the third gate 16 are closed to drain the food processing liquid in the inlet section 11 and the outlet section 13. Then, the fourth gate 17 is opened to remove the material from the outlet section 13.

[0087] By opening and closing the gate, the material is fed into the processing tank 1 in a horizontal manner while the processing liquid is present. It is then fed through and removed from the processing tank. This ensures proper cooking and processing without causing significant lifting or lowering of the material, thus reducing the overall height of the equipment. Furthermore, the conveying mechanism causes the material to move slightly up and down relative to the processing liquid during the conveying process, which agitates the material and ensures more thorough contact between the material and the processing liquid. The impact of the processing liquid on the material prevents the stacked material from sticking together and failing to make effective contact with the processing liquid, thereby improving the thoroughness and quality of the cooking process.

[0088] like Figure 15 As shown, in one embodiment, the conveying mechanism includes a first conveying section 61, a second conveying section 62, and a third conveying section 63. The first conveying section is located in the inlet section 11, the second conveying section is located in the middle section 12, and the third conveying section 63 is located in the outlet section 13. The conveying paths of the first conveying section 61, the second conveying section 62, and the third conveying section 63 are along the length of the processing tank 1, and the three sections are connected to convey materials. That is, the overall conveying path of the first conveying section 61, the second conveying section 62, and the third conveying section 63 is all transverse, and there is no inclined section to lift the material. Specifically, the first conveying section 61, the second conveying section 62, and the third conveying section 63 can be conveyor chains arranged at the bottom of the processing tank 1.

[0089] The steps of the food processing method using the food processing device include:

[0090] In the state that the second gate 15 and the third gate 16 are closed and the inlet section 11 and the outlet section 13 are emptied of the food processing liquid, the first gate 14 is opened, and the conveying unit is sent into the inlet section 11 through the inlet, in which the conveying unit is directly entered into the inlet section 11 in a transverse manner, and the conveying unit in the inlet section 11 is on the first conveying section 61;

[0091] The first gate 14 and the fourth gate 17 are closed, and then the second gate 15 and the third gate 16 are opened, and the food processing liquid is supplemented into the processing tank 1, so that the inlet section 11, the middle section 12 and the outlet section 13 are in a communication state;

[0092] The conveying mechanism starts to work, and the first conveying section 61 enters the middle section 12 through the opened second gate 15 along the transverse direction, the second conveying section 62 in the middle section 12 receives the conveying unit sent by the first conveying section 61, and after the conveying unit completely enters the middle section 12, the second conveying section 62 drives the conveying unit to move towards the outlet section 13, and then the conveying unit enters the outlet section 13 by passing through the opened third gate 16, the third conveying section 63 in the outlet section 13 receives the conveying unit sent by the second conveying section 62, and after the third conveying section 63 drives the conveying unit to completely enter the outlet section 13, the conveying mechanism stops;

[0093] After the conveying unit enters the outlet section 13, the second gate 15 and the third gate 16 are closed, the food processing liquid in the inlet section 11 and the outlet section 13 is emptied, and then the fourth gate 17 is opened to take out the conveying unit from the outlet section 13.

[0094] During the whole process of the conveying unit moving along the processing tank 1, the food processing liquid in the processing tank 1 is cooking the material, and the conveying unit only moves in the transverse direction, without large up-and-down movement, so that the material can be kept as a whole to move in the transverse direction through the processing tank with the food processing liquid in the processing tank, which can guarantee good cooking processing, and make the whole food processing device compact in structure, small in size and save production space.

[0095] As Figure 16As shown, in an embodiment, the conveying mechanism comprises a hoisting conveying line 7 arranged above the processing tank 1, the conveying path of the hoisting conveying line 7 is along the length direction of the processing tank 1, and the material is hoisted on the hoisting conveying line 7 to travel along the processing tank 1. The structure is simple, compact, and convenient to implement. Due to the specific structure of the processing tank 1, the conveying path of the hoisting conveying line 7 is entirely along the transverse direction, and does not need to be arranged as a concave curve as in the prior art, which is simple in structure, occupies less height space, and has good conveying stability for the material. For this embodiment, since the hoisting conveying line 7 is arranged above the processing tank 1, the first gate 14, the second gate 15, the third gate 16, and the fourth gate 17 are transversely opened and closed, so as not to interfere with the hoisting conveying line 7, thereby ensuring that the material is kept in the form of traveling along the transverse direction through the processing tank 1 under the condition that the food processing liquid is stored in the processing tank 1.

[0096] The steps of the food processing method using the food processing device include:

[0097] In the state that the second gate 15 and the third gate 16 are closed and the inlet section 11 and the outlet section 13 are emptied of the food processing liquid, the first gate 14 is opened, and the conveying unit is sent into the inlet section 11 through the inlet, in which the conveying unit directly enters the inlet section 11 in the form of traveling along the transverse direction, and the conveying unit entering the inlet section 11 is hoisted and connected to the hoisting conveying line 7;

[0098] The first gate 14 and the fourth gate 17 are closed, and then the second gate 15 and the third gate 16 are opened to supplement the food processing liquid into the processing tank 1, at this time, the inlet section 11, the middle section 12, and the outlet section 13 are in a connected state;

[0099] The conveying mechanism starts to work, the hoisting conveying line 7 drives the conveying unit to travel along the length direction of the processing tank 1 along the transverse direction, the conveying unit entering the inlet section 11 enters the middle section and finally enters the outlet section 13;

[0100] After the conveying unit enters the outlet section 13, the second gate 15 and the third gate 16 are closed, the food processing liquid in the inlet section 11 and the outlet section 13 is emptied, and then the fourth gate 17 is opened to take out the conveying unit from the outlet section 13.

[0101] During the whole process of the conveying unit moving along the processing tank 1, the food processing liquid in the processing tank 1 is all in the process of cooking the material, and the conveying unit only moves in the transverse direction, without large up and down movement, so that the material can pass through the processing tank in the way of keeping the whole transverse movement under the condition of the food processing liquid in the processing tank, which can guarantee the good cooking process, and make the whole food processing device compact in structure, small in size and save production space. Moreover, the hoisting conveying line 7 above the processing tank 1 is completely not in contact with the food processing liquid in the processing tank 1, so that the residues generated by the mechanical wear of the hoisting conveying line 7 itself cannot enter the food processing liquid, thereby effectively avoiding the pollution of the food processing liquid and guaranteeing the health and safety of the food processing.

[0102] The above is only the preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application, and the protection scope of the present application should be limited by the scope defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
