Description

Technical Field

[0001] The invention belongs to the field of cooking robots, and in particular relates to a modular continuous dish cooking processing device and method. Background Art

[0002] In recent years, the field of cooking robots has developed rapidly, and various types of cooking robots have been continuously launched. They have been widely used in central kitchens, chain restaurants, unit canteens, and military field logistics support. Cooking robots can effectively reduce labor costs and save physical exertion. At the same time, the mobility of catering chefs is relatively large. Taking leave, job hopping, etc. will lead to large differences in the dishes served each time, which cannot stabilize customers. The dishes provided by cooking robots have high stability in quality and flavor. Cooking robots have greater advantages in situations where there is a large demand for the same dishes. However, traditional cooking robots only simulate the actions and processes of chefs cooking. To increase production, a larger pot body needs to be designed. When the large pot is stir-fried, the raw materials have less contact with the high-temperature bottom, and it takes a long time to stir-fry, and it is difficult to mix the seasoning with other raw materials. Some cooking robots have a narrow range of choices in the variety of dishes, and the same cooking robot can only cook a limited number of dishes. The catering industry and dish processing companies need an automated dish frying processing technology that breaks conventional thinking, has a higher degree of automation, a wider adaptability, and a stronger processing capacity. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects described in the prior art, thereby providing a modular continuous dish frying processing device and method, which can complete the continuous automated processing of dishes while meeting the use scenarios that require intermittent supply. The modular design can meet the requirements of more dish processing techniques and has a high market practical application value. In order to achieve the above purpose, the present invention provides the following technical solutions: A modular continuous dish frying and processing device includes a pre-processing conveying device, a dish processing system and a feeding system. The pre-processing conveying device is a horizontally placed cylindrical screw conveying device, which is internally provided with a heating and temperature control device to provide a suitable temperature for pre-processing processes such as mixing, seasoning, and pickling; a feeding port is provided at the upper part of the conveying device sleeve, and feeding ports of different positions and sizes are provided according to the dish process; a screen drain port is provided at the bottom of the conveying device sleeve, and the tail of the pre-processing conveying device is connected to the dish processing system, and the dish raw materials enter the pre-processing conveying device and the dish processing system through the feeding system to complete the frying of the dish.

[0004] The dish processing system is divided into three different processing modules, namely, a centralized frying module, a separate frying module and a stewing module. Different types and numbers of modules are selected for combination according to different dish processes.

[0005] The centralized frying module is composed of a sheet-type heating center axis and a sleeve. The sleeve serves as the outer shell of the sheet-type heating center axis and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules.

[0006] The sheet-type heating center axis is composed of a hollow rotating tube, a plurality of fan-shaped heating sheets and a plurality of centralized module liquid material feeding ports. The hollow rotating tube is vertically located in the center of the centralized frying module, and a splicing section is arranged at the top and bottom of the hollow rotating tube. According to the cooking process, multiple hollow rotating tubes can be assembled and installed, and a motor is arranged above the assembled hollow rotating tube to drive the hollow rotating tube to rotate.

[0007] The fan-shaped heating plates are horizontally arranged on the wall of the rotating tube. According to the cooking process, fan-shaped heating plates of different numbers, spacings, and areas are arranged. Each fan-shaped heating plate has an independent temperature control system and can be set to different temperatures. The fan-shaped heating plates rotate with the hollow rotating tube, and can provide a high-temperature contact surface and a horizontal flipping force for the falling raw materials while stirring and mixing the raw materials.

[0008] The centralized module liquid material feeding port can be set at different positions according to the dish process. When it is set at the connection between the fan-shaped heating plate and the rotating tube, the discharged liquid material is spread on the fan-shaped heating plate due to the centrifugal force; when passing through the inside of the fan-shaped heating plate, the liquid material is preheated before flowing out; when it is set on the rotating tube wall, the discharged liquid material is thrown outward due to the centrifugal force.

[0009] The separation frying module is composed of a tubular heating central axis and a sleeve. The sleeve serves as the outer shell of the tubular heating central axis and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules.

[0010] The tubular heating center axis is composed of a hollow rotating tube, a separation turntable, an annular partition, a plurality of groups of heating tubes and a plurality of separation module liquid material feeding ports. The rotating tube is the same as that in the centralized frying module and can be spliced ​​with each other.

[0011] The separation turntable is in the shape of a mesh disk, located at the upper part of the hollow rotating tube, high inside and low outside, with mesh holes arranged from small to large from the inside to the outside. It rotates with the rotation of the hollow rotating tube, and the raw materials falling onto the separation turntable move outward, and materials of different shapes or sizes fall below through mesh holes of corresponding sizes.

[0012] One end of the heating tube is arranged on the hollow rotating tube wall, and the other end extends horizontally outward and is perpendicular to the rotating tube. According to the cooking process, a certain number and a certain length of heating tubes are arranged on the same horizontal plane to form a group of heating tubes; The central axis of the annular partition coincides with the hollow rotating tube. According to the cooking process, a certain number of annular partitions with a certain interval are set to divide the central axis of the tubular heating into several independent spaces. The heating tube passes through each layer of annular partitions, which are fixed on the heating tube and divide the heating tube into several sections. By controlling the density of the heating wire inside each section, different heating temperatures can be set for each section. As the hollow rotating tube rotates, raw materials of different shapes or sizes fall into different intervals and touch heating tube sections of different temperatures when falling.

[0013] The liquid material feeding port of the separation module passes through the interior of the heating tube and opens upward on the outer side of the connection between the hollow rotating tube and the annular partition. A suitable heating tube can be selected according to the dish process, and a suitable number and position of feeding ports can be set.

[0014] The fan-shaped heating sheet and the heating tube can be mixed and installed according to the process requirements. The fan-shaped heating sheet has a large raw material contact area, the raw material falls slowly, and the heating time is long. It can also be installed in the separate frying module. The heating tube has a small raw material contact area, a short heating time, is not easy to stick to the raw material, and can also be installed in the centralized frying module.

[0015] The stewing module is a horizontally placed cylindrical screw conveying device. According to the conveying direction, an upward splicing interface is provided at the front of the stewing module, which can be spliced ​​with other modules. A downward oblique discharge port is provided at the rear of the stewing module, which can be spliced ​​with other modules or connected to subsequent packaging equipment. A heating device is provided inside, and different heating temperatures are set in different sections. Several feed ports are provided on the upper part of the horizontal cylindrical outer jacket to add solid materials, liquid materials or water. A liquid material circulation system is provided, connecting the bottom of the end and the front feed port. After opening, the liquid material falling through the screen at the bottom of the end of the device can be transported to the feed port or the excess liquid can be discharged.

[0016] The feeding system is composed of an initial feeding system, an intermediate feeding system and an internal feeding system, and all feeding systems are various types of conveying pipes that can control flow. The various pipes of the initial feeding system are connected to the feed port of the pre-treatment conveying device, the various pipes of the intermediate feeding system are connected to the top opening or feed port of each frying module, and the various pipes of the internal feeding system enter the hollow rotating tube of the frying module from the top and do not rotate with the hollow rotating tube. The inner wall of the hollow rotating tube at the corresponding position of each liquid material feeding port is provided with an annular groove, and the groove is communicated with the liquid material feeding port outwardly. The corresponding feeding system pipe is provided with a fork here to penetrate into the annular groove, and a flow control device is provided, but it does not touch the groove wall. The liquid first enters the annular groove and then completes the feeding through the liquid material feeding port.

[0017] A modular continuous dish frying processing method comprises the following steps: (1) Preparation of raw materials before frying. Before frying the dish, all raw materials must be processed into a state that can be directly processed and connected to various conveying pipelines of the feeding system through conveying equipment.

[0018] (2) Input of various raw materials. ① Various raw materials required for pre-treatment and the start of frying: input from the initial feeding system to the feed port of the pre-treatment conveying device through the corresponding pipeline; ② Solid, semi-solid and high-viscosity liquid materials required in the intermediate process of frying: input from the intermediate feeding system to the top opening or feed port of each frying module through the corresponding pipeline; ③ Liquid raw materials required in the intermediate process of frying: input from the internal feeding system through the corresponding pipeline into the annular groove on the inner wall of the hollow rotating tube, and complete the feeding from the liquid material feeding port, or directly input from the intermediate feeding system.

[0019] (3) Pretreatment of raw materials. Pretreatment processes of different modes can be completed according to process requirements. Mode ①: Mixing of a very small amount of auxiliary materials with the main raw materials. Connect the pipeline of the auxiliary materials to the feed port located in the middle of the pretreatment conveying device, and control the feed speed of the auxiliary materials. Add them to the main raw materials that are uniformly conveyed, and complete the mixing through the stirring action of the rotating screw. The uniform, small-scale and continuous production greatly improves the mixing efficiency. Mode ②: Pickling mode. Connect the pipelines of the raw materials to be pickled and the corresponding seasoning auxiliary materials to the feed port located at the front position of the pretreatment conveying device. Select a pretreatment conveying device with a larger diameter and a slower conveying speed to meet the pickling time requirements while ensuring processing efficiency. If there is excess liquid, it can be discharged through the bottom screen drain port. It is also possible to select two pretreatment conveying devices with different diameters in series, and the raw materials pickled at the front end are then input into the pretreatment conveying device at the back end to be mixed with other required raw materials. Mode ③: Preheating mode. Adjust the internal temperature of the pretreatment conveying device according to process requirements to complete the required preheating process during the conveying process.

[0020] (4) Selection and combination of processing modules. According to the process requirements, different numbers and types of processing modules are combined to complete the processing of different modes of dishes. The selected two stir-frying modules of different numbers can be vertically spliced ​​up and down through a hollow rotating tube, and the bottom opening of the sleeve of the upper module is larger than the top opening of the next module. When stewing, braising and other processes are required, a stewing module is added at the bottom or in the middle of the series-connected stir-frying modules.

[0021] (5) Stir-frying of dishes.

[0022] ① Processing process inside the centralized frying module: The raw materials processed in the previous step enter the centralized frying module from the top opening, and the raw materials fall onto the surface of the fan-shaped heating plate. The fan-shaped heating plate rotates horizontally, and the raw materials that come into contact with it are horizontally flipped by force, and experience several bounces and falls during flipping, completing multiple high-temperature surface contacts in different directions. According to the dish process, set the fan-shaped heating plates with appropriate number, spacing and area, select the appropriate rotation speed and temperature of the fan-shaped heating plates, and the raw materials complete enough high-temperature surface contacts during the continuous falling process. According to the dish process, set the appropriate number and position of liquid material feeding ports, and the liquid material, such as vegetable oil, that flows out of the fan-shaped heating plate is heated and contaminated on the surface of the falling raw materials; the liquid material preheated inside the fan-shaped heating plate is evenly sprinkled on the raw materials; the room-temperature liquid material thrown out from the feeding port on the rotating tube wall is evenly sprinkled on the falling raw materials. According to the dish process, add the appropriate raw materials that need to be added during the frying process through the intermediate feeding system.

[0023] ② Internal processing of the separation and frying module: The raw materials processed in the previous step enter the separation and frying module from the top opening. The raw materials fall onto the separation turntable and move outward. Raw materials of different sizes and characteristics fall into different annular compartment spaces and touch heating tube sections of different temperatures when falling. According to the dish process, select the appropriate number and spacing of heating tubes and annular compartments, select the appropriate rotation speed and temperature of each section of the heating tube, and different raw materials complete their own appropriate high-temperature surface contact during the continuous falling process. According to the dish process, set a suitable liquid material feeding port to add the required liquid to a specific annular compartment space. According to the dish process, the pipeline of the intermediate feeding system is directly inserted into the specific annular compartment space through the top opening to add the raw materials needed to be added to the space during the frying process.

[0024] ③ Processing process inside the stewing module: The raw materials processed in the previous step enter the stewing module through the splicing interface. According to the dish process, various other raw materials required are added through the intermediate feeding system. The stewing and braising processes are carried out by adjusting the temperature of the heating device and the conveying speed. Before the processed dishes are conveyed to the discharge port, they will pass through the liquid circulation system. The excess liquid will fall through the screen. By controlling the circulation or direct discharge speed, the solid-liquid ratio of the dishes output from the discharge port or the overall solid-liquid ratio in the cavity can be adjusted.

[0025] (6) Continuous processing and intermittent supply of dishes. Coordinate the operating speed of all modules to evenly and continuously output the dishes after frying to the subsequent packaging and other processes. When the dishes after frying need to be temporarily stored for use, all dishes enter the stewing module, stop the operation of other modules, adjust the temperature of the stewing module for insulation, and suspend the delivery. When necessary, open the delivery switch until a sufficient amount of dishes is obtained, then close it and wait for the next supply.

[0026] (7) Cleaning of the device. The liquid material feeding system of this device goes deep into the interior of each module, and each module forms a whole connected by chambers. The liquid material feeding system is connected to the external CIP cleaning system to complete the cleaning of the device.

[0027] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can not only complete the continuous processing of dishes, but also meet the usage scenarios that require intermittent supply.

[0028] (2) When frying in a large pot, the raw materials have little chance to contact with the high-temperature bottom, so it takes a long time to fry, and it is difficult to mix the seasoning with other raw materials. The present invention can achieve efficient contact between the raw materials and the high-temperature surface, and efficient mixing of the seasoning with other raw materials. (3) The temperature of the present invention is controllable in sections, and different temperatures can be set for raw materials at different stages. The present invention can also separate different raw materials and provide different heating temperatures for raw materials with different temperature requirements at the same time.

[0029] (4) The present invention meets the needs of different processes by arranging and combining modules of different types and quantities, and is suitable for more dish processes.

[0030] (5) The present invention can set different positions and different numbers of outlets of the liquid material feeding system, which can realize the functions of preheating the liquid material before feeding, forming an oil film on the heating surface, spraying at room temperature, automatic adding, etc. The intermediate feeding system of the present invention can add raw materials to each module during the intermediate processing.

[0031] (6) The pre-treatment conveying device of the present invention can realize continuous processing of pickling, seasoning mixing and other processes.

[0032] (7) The present invention is provided with a screen liquid discharge port and a liquid material circulation system, which can adjust the solid-liquid ratio of the dish output from the discharge port, or the overall solid-liquid ratio in the cavity.

[0033] (8) The liquid material feeding system of the present invention penetrates into the interior of each module, and each module forms a whole connected by chambers. The liquid material feeding system is connected to an external CIP cleaning system to complete the cleaning of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The dish processing system 2 is divided into three different processing modules, namely, a centralized frying module 6, a separate frying module 7 and a stewing module 8. Different types and numbers of modules are selected for combination according to different dish processes.

[0039] The centralized frying module 6 is composed of a sheet-type heating center shaft 9 and a sleeve 10. The sleeve 10 serves as the outer shell of the sheet-type heating center shaft 9 and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules. The sheet-type heating center shaft 9 is composed of a hollow rotating tube 11, a plurality of fan-shaped heating sheets 12 and a plurality of centralized module liquid material feeding ports 13.

[0040] The hollow rotating tube 11 is vertically located at the center of the centralized frying module 6. Splicing sections are provided at the top and bottom of the hollow rotating tube 11. According to the cooking process, multiple hollow rotating tubes 11 can be installed in combination. A motor 14 is provided above the combined hollow rotating tube 11 to drive the hollow rotating tube 11 to rotate.

[0041] The fan-shaped heating plates 12 are horizontally arranged on the wall of the rotating tube. According to the cooking process, fan-shaped heating plates 12 of different numbers, spacings, and areas are arranged. Each fan-shaped heating plate 12 has a separate temperature control system and can be set to different temperatures. The fan-shaped heating plates 12 rotate with the hollow rotating tube 11, and can provide a high-temperature contact surface and a horizontal flipping force for the falling raw materials while stirring and mixing the raw materials.

[0042] The centralized module liquid material feeding port 13 can be set at different positions according to the dish process. When it is set at the connection between the fan-shaped heating plate 12 and the hollow rotating tube 11, the discharged liquid material is spread on the fan-shaped heating plate 12 due to the centrifugal force; when passing through the inside of the fan-shaped heating plate 12, the liquid material is preheated before flowing out; when it is set on the wall of the hollow rotating tube 11, the discharged liquid material is thrown outward due to the centrifugal force.

[0043] The separation and frying module 7 is composed of a tubular heating central axis 15 and a sleeve 10. The sleeve 10 serves as the outer shell of the tubular heating central axis 15 and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules. The tubular heating central axis 15 is composed of a hollow rotating tube 11, a separation turntable 16, an annular spacer 17, a plurality of groups of heating tubes 18 and a plurality of separation module liquid material feeding ports 19.

[0044] The hollow rotating tube 11 is the same as that in the centralized frying module 6 and can be spliced ​​with each other. The separation turntable 16 is in the shape of a mesh disk, located at the upper part of the hollow rotating tube 11, high inside and low outside, with mesh holes arranged from small to large from inside to outside, rotating with the rotation of the hollow rotating tube 11, and the raw materials falling onto the separation turntable 16 move outward, and materials of different shapes or sizes fall below through mesh holes of corresponding sizes.

[0045] One end of the heating tube 18 is arranged on the wall of the hollow rotating tube 11, and the other end extends horizontally outward and is perpendicular to the hollow rotating tube 11. According to the cooking process, a certain number and a certain length of heating tubes 18 are arranged on the same horizontal plane to form a group of heating tubes 18; the central axis of the annular partition 17 coincides with the hollow rotating tube 11. According to the cooking process, a certain number and a certain interval of annular partitions 17 are arranged to divide the tubular heating center axis 15 into several independent spaces. The heating tube 18 passes through each layer of annular partition 17, and the annular partition 17 is fixed on the heating tube 18, and the heating tube 18 is divided into several sections. By controlling the density of the heating wire 19 inside each section, different heating temperatures can be set for each section. As the hollow rotating tube 11 rotates, different raw materials fall into different intervals and touch the heating tube 18 sections with different temperatures when falling.

[0046] The liquid material feeding port 19 of the separation module passes through the interior of the heating tube 18 and opens upward on the outer side of the connection between the hollow rotating tube 11 and the annular partition 17. A suitable heating tube 18 can be selected according to the dish process, and a suitable number and position of feeding ports can be set.

[0047] The fan-shaped heating plate 12 and the heating tube 18 can be mixed and installed according to the process requirements. The fan-shaped heating plate 12 has a large raw material contact area, the raw material falls slowly, and the heating time is long. It can also be installed in the separate frying module 7. The heating tube 18 has a small raw material contact area, a short heating time, is not easy to stick to the raw material, and can also be installed in the centralized frying module 6.

[0048] The stewing module 8 is a horizontally placed cylindrical screw conveying device. According to the conveying direction, the front of the stewing module 8 is provided with an upward splicing interface 20, which can be spliced ​​with other modules. The tail of the stewing module 8 is provided with an oblique downward discharge port 21, which can be spliced ​​with other modules or connected to subsequent packaging equipment. A heating device is provided inside, and different heating temperatures are set in different sections. A plurality of feed ports 4 are provided on the upper part of the horizontal cylindrical outer jacket to add solid materials, liquid materials or water. A liquid material circulation system 22 is provided, which connects the bottom of the end and the front feed port 4. After opening, the liquid material falling through the screen at the bottom of the end of the device can be transported to the feed port 4 or the excess liquid can be discharged.

[0049] The feeding system 3 is composed of an initial feeding system 23, an intermediate feeding system 24 and an internal feeding system 25. All feeding systems 3 are various types of conveying pipes that can control flow. The various types of pipes of the initial feeding system 23 are connected to the feed port 4 of the pre-treatment conveying device, and the various types of pipes of the intermediate feeding system 24 are connected to the top opening or feed port 4 of each frying module. The various types of pipes of the internal feeding system 25 enter the hollow rotating tube 11 of the frying module from the top and do not rotate with the hollow rotating tube 11. The inner wall of the hollow rotating tube 11 at the corresponding position of each liquid material feeding port (13, 19) is provided with an annular groove 26, and the groove is communicated with the liquid material feeding port (13, 19) outwardly. The corresponding feeding system pipe is provided with a fork 27 here to penetrate into the annular groove, and a flow control device 28 is provided, but does not touch the groove wall. The liquid first enters the annular groove and then completes the feeding through the liquid material feeding port.

[0050] A modular continuous dish frying processing method, taking the preparation of twice-cooked pork as an example, comprises the following steps: (1) The processed sliced ​​pork or pork belly to be fried is fed into the pre-processing conveying device 1 by the initial feeding system 23. At the same time, seasonings such as cooking wine are fed into the pre-processing conveying device 1 at the rear of the meat and sprayed on the meat. The meat is fully contacted and mixed with the seasonings during the conveying process.

[0051] (2) The processed meat is transported to the first centralized frying module 6. The meat itself has a high fat content, and the vegetable oil is fed at a lower flow rate through the centralized module liquid material feeding port 13 set at the connection between the fan-shaped heating plate 12 and the hollow rotating tube 11. The vegetable oil is spread on the fan-shaped heating plate 12 with centrifugal force to form an oil film to prevent the meat from sticking; the fan-shaped heating plate 12 rotates horizontally, and the meat falls onto the surface of the fan-shaped heating plate 12, constantly flipping, bouncing and falling, completing multiple high-temperature surface contacts in different directions. The meat completes enough high-temperature surface contacts during the continuous falling process. According to the thickness of the meat slices and the taste requirements of the customers, set the appropriate number, spacing and area of ​​fan-shaped heating plates 12, select the appropriate rotation speed and temperature of the fan-shaped heating plates 12, the thinner the meat slices, the more delicate the taste requirements, and the corresponding number and lower temperature are set.

[0052] (3) The fried meat falls into the separation and frying module 7 below, which is divided into two layers by the annular partition 17. The meat has a high fat content in the previous step of processing, and oil is produced after heat processing. These lard and meat slices first fall onto the separation turntable 16, moving from the inside to the outside. The lard falls into the inner layer through the smaller mesh holes, and the lard drips onto the heating tube 18 below to form an oil film. The intermediate feeding system 24 inputs seasoning ingredients such as pepper, dried chili, fermented black beans, sweet noodle sauce, minced ginger and garlic into the inner layer where the lard falls, and continuously contacts the oil film on the heating tube 18 to fry out the aroma; the meat falls into the outer layer at a more outer position and a suitable mesh hole to continue frying; the heating tubes of the two sections are set at different temperatures, and the temperature of the outer section should be lower than that of the inner section to prevent the high oil temperature from frying the outer layer of meat slices dry and hard, and the slightly higher temperature of the inner layer helps the seasoning to stimulate the flavor.

[0053] (4) All the raw materials processed in the previous step fall into the second centralized frying module 6 below. Raw materials such as green pepper, garlic sprouts, and sugar are input from the intermediate feeding system 24, and liquid materials such as soy sauce and cooking wine are input from the centralized module liquid material feeding port 13 on the wall of the hollow rotating tube 11. The stirring effect of the fan-shaped heating plate 12 mixes the flavor-stimulated seasoning with other raw materials, completing the mixed frying of all raw materials.

[0054] (5) The processed raw materials in the previous step fall into the stewing module 8 below, and the intermediate feeding system 24 inputs a small amount of chopped green onions, adjusts the appropriate temperature and speed, and outputs them evenly and continuously to subsequent packaging and other processes after stewing for a period of time. When they need to be temporarily stored and wait for use, all dishes enter the stewing module 8, stop the operation of other modules, adjust the temperature of the stewing module 8 for insulation, and suspend the delivery. When necessary, turn on the delivery switch until a sufficient amount of dishes is obtained, then turn it off and wait for the next supply.

[0055] (7) Cleaning of the device. The liquid material feeding system of this device goes deep into the interior of each module, and each module forms a whole connected by chambers. The liquid material feeding system can be connected to the external CIP cleaning system to complete the cleaning of the device.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

The sleeve serves as the outer shell of the sheet-type heating center axis, and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules. The sheet-type heating center axis is composed of a hollow rotating tube, a plurality of fan-shaped heating plates, and a plurality of centralized module liquid material feeding ports. The hollow rotating tube is vertically located at the center of the centralized frying module. The top and bottom of the hollow rotating tube are provided with a splicing section. According to the cooking process, multiple hollow rotating tubes can be assembled and installed. A motor is provided above the assembled hollow rotating tube to drive the hollow rotating tube to rotate. The fan-shaped heating plate is horizontally arranged on the rotating tube wall. According to the cooking process, fan-shaped heating plates of different numbers, spacings, and areas are arranged.

The fan-shaped heating plate rotates with the hollow rotating tube, and can provide a high-temperature contact surface and a horizontal flipping force for the falling raw materials while stirring and mixing the raw materials. The centralized module liquid material feeding port can be set at different positions according to the dish process. When it is set at the connection between the fan-shaped heating plate and the rotating tube, the discharged liquid material is spread on the fan-shaped heating plate due to the centrifugal force; when passing through the inside of the fan-shaped heating plate, the liquid material is preheated before flowing out; when it is set on the rotating tube wall, the discharged liquid material is thrown outward due to the centrifugal force.

4. The separation frying module according to claim 2 is composed of a tubular heating central axis and a sleeve. The sleeve serves as the outer shell of the tubular heating central axis, and constrains the flow direction and space of the raw materials inside the module and at the joints of different modules.

According to the cooking process, a certain number and a certain interval of annular spacers are arranged to separate the tubular heating central axis into several independent spaces. The heating tube passes through each layer of annular spacers, which are fixed on the heating tube and divide the heating tube into several sections. By controlling the density of the heating wire inside each section, different heating temperatures can be set for each section. As the hollow rotating tube rotates, raw materials of different shapes or sizes fall into different intervals and touch heating tube sections of different temperatures when falling. The liquid material feeding port of the separation module passes through the inside of the heating tube and opens upward on the outside of the connection between the hollow rotating tube and the annular spacer. According to the cooking process, a suitable heating tube can be selected and a feeding port of a suitable number and position can be set.

8. A modular continuous dish frying processing method, comprising the following steps: (1) Preparation of raw materials before frying. Before the frying process of this dish, all raw materials must be processed into a state that can be directly processed, and connected to various conveying pipes of the feeding system through conveying equipment. (2) Input of various required raw materials. ① Various raw materials required for pre-treatment and the start of frying: input into the feed port of the pre-treatment conveying device through the corresponding pipes by the initial feeding system; ② Solid, semi-solid and high-viscosity liquid materials required in the middle of frying: input into the top opening or feed port of each frying module through the corresponding pipes by the intermediate feeding system; ③ Liquid raw materials required in the middle of frying: input into the annular groove on the inner wall of the hollow rotating tube through the corresponding pipes by the internal feeding system, and complete the feeding from the liquid material feeding port, or directly input by the intermediate feeding system. (3) Pre-treatment of raw materials. Different modes of pre-treatment processes can be completed according to the process requirements. Mode ①: Mixing of a very small amount of auxiliary materials with the main raw materials. Connect the pipeline of the auxiliary materials to the feed port located in the middle of the pre-treatment conveying device, and control the feed speed of the auxiliary materials. Add them to the main raw materials that are uniformly conveyed, and complete the mixing through the stirring action of the rotating screw. The uniform, small-scale and continuous production greatly improves the mixing efficiency. Mode ②: Pickling mode. Connect the pipelines of the raw materials to be pickled and the corresponding seasoning auxiliary materials to the feed port located at the front position of the pre-treatment conveying device. Select a pre-treatment conveying device with a larger diameter and a slower conveying speed to meet the pickling time requirements while ensuring processing efficiency. If there is excess liquid, it can be discharged through the bottom screen drain port. It is also possible to select two pre-treatment conveying devices with different diameters to be connected in series. The raw materials pickled at the front end are then input into the pre-treatment conveying device at the back end to be mixed with other required raw materials. Mode ③: Preheating mode.

The selected two stir-frying modules of different numbers can be spliced ​​vertically up and down through a hollow rotating tube, and the bottom opening of the sleeve of the upper module is larger than the top opening of the next module. When stewing, braising and other processes are required, a stewing module is added to the bottom or middle of the series stir-frying modules. (5) Stir-frying processing of dishes. ① Processing process inside the centralized stir-frying module: The raw materials processed in the previous step enter the centralized stir-frying module from the top opening, and the raw materials fall onto the surface of the fan-shaped heating plate. The fan-shaped heating plate rotates horizontally, and the raw materials that come into contact with it are horizontally flipped by force, and experience several bounces and falls during the flipping, completing multiple high-temperature surface contacts in different directions. According to the cooking process, set the appropriate number, spacing and area of ​​fan-shaped heating plates, select the appropriate rotation speed and temperature of the fan-shaped heating plates, and ensure that the raw materials have enough high-temperature surface contact during the continuous falling process. According to the cooking process, appropriate number and position of liquid feeding ports are set, and liquid, such as vegetable oil, etc., spread on the fan-shaped heating plate flows out and is heated while being coated on the surface of the falling raw materials; the preheated liquid passes through the fan-shaped heating plate and is evenly sprinkled on the raw materials; the room temperature liquid thrown out from the feeding port on the rotating tube wall is evenly sprinkled on the falling raw materials. According to the cooking process, appropriate raw materials that need to be added during the cooking process are added through the intermediate feeding system. ② Processing process inside the separation and cooking module: The raw materials processed in the previous step enter the separation and cooking module from the top opening. The raw materials fall onto the separation turntable and move outward. Raw materials of different sizes and characteristics fall into different annular compartment spaces and touch heating pipe sections of different temperatures when falling. According to the cooking process, select the appropriate number and spacing of heating tubes and annular partitions, select the appropriate rotation speed and temperature of each section of the heating tube, so that different raw materials can achieve their own appropriate high-temperature surface contact during the continuous falling process. According to the dish craft, set the appropriate liquid material feeding port and add the required liquid material into the specific annular compartment space. According to the dish process, the pipe of the intermediate feeding system is directly inserted into the specific annular compartment space through the top opening, and the raw materials needed to be added during the frying process are added to the space. ③ Processing process inside the stewing module: The raw materials processed in the previous step enter the stewing module through the splicing interface. According to the dish process, various other raw materials required are added through the intermediate feeding system. The stewing and braising processes are carried out by adjusting the temperature of the heating device and the conveying speed. Before the processed dishes are conveyed to the discharge port, they will pass through the liquid material circulation system. The excess liquid will fall through the screen. By controlling the circulation or direct discharge speed, the solid-liquid ratio of the dishes output from the discharge port or the overall solid-liquid ratio in the cavity can be adjusted. (6) Continuous processing and intermittent supply of dishes. Coordinate the operating speed of all modules, and the dishes after frying are evenly and continuously output to subsequent packaging and other processes. When the dishes that have been processed need to be temporarily stored for use, all dishes enter the stewing module, stop the operation of other modules, adjust the temperature of the stewing module for insulation, and suspend the conveying. When necessary, turn on the conveying switch until a sufficient amount of dishes is obtained and then turn it off to wait for the next supply. (7) Cleaning of the device. The liquid material feeding system of this device goes deep into the interior of each module, and each module forms a whole connected by chambers. The liquid material feeding system is connected to the external CIP cleaning system to complete the cleaning of the device.
