Description

Technical Field

[0001] The present invention relates to the technical field of food processing, specifically to a processing technology and equipment for fish tofu. Background Technique

[0002] Fish tofu is a kind of delicacy obtained by mixing fish meat and flour to get a slurry and then dividing it into pieces for frying.

[0003] In the traditional process of processing fish tofu, when frying fish tofu, the oil temperature near the fish tofu will drop rapidly. In order to maintain the oil temperature, it is necessary to increase the content of hot oil, so as to increase the proportion of high-temperature hot oil in the hot oil exchange process and then maintain the oil temperature; this limits the amount of fish tofu that can be processed simultaneously with the unit heat input per unit volume, further reducing the processing efficiency of fish tofu and increasing the loss of hot oil.

[0004] Based on this, the present invention designs a processing technology and equipment for fish tofu to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a processing technology and equipment for fish tofu to solve the problem that in the traditional process of processing fish tofu, when frying fish tofu, the oil temperature near the fish tofu will drop rapidly. In order to maintain the oil temperature, it is necessary to increase the content of hot oil, so as to increase the proportion of high-temperature hot oil in the hot oil exchange process and then maintain the oil temperature; this limits the amount of fish tofu that can be processed simultaneously with the unit heat input per unit volume, further reducing the processing efficiency of fish tofu and increasing the loss of hot oil.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A fish tofu processing equipment, including a U-shaped pot, a U-shaped mounting plate, a transmission mechanism, a discharging mechanism and a pushing mechanism. The discharging mechanism is arranged above the U-shaped pot for inputting prefabricated materials into the U-shaped pot. A blanking channel surrounded by the U-shaped pot is formed at the center of the U-shaped pot for discharging finished products. The U-shaped mounting plate is arranged inside the U-shaped pot. The transmission mechanism is arranged in the U-shaped mounting plate. The pushing mechanism is arranged on the transmission mechanism. The pushing mechanism is used to push the prefabricated materials from the upper end of the U-shaped pot along the inner wall of the U-shaped pot into the center of the U-shaped pot for discharging. The U-shaped pot is filled with hot oil and can heat the hot oil.

[0007] As a further solution of the present invention, the inner wall of the U-shaped pot includes an arc section at the bottom. The U-shaped mounting plate is arranged directly above the arc section. One side of the arc section away from the center of the U-shaped pot is connected with an inclined section. The vertical distance from the inclined section to the U-shaped mounting plate gradually increases from bottom to top. One side of the arc section close to the center of the U-shaped pot is connected with a vertical section. The vertical distances from the arc section and the vertical section to the U-shaped mounting plate are equal and unchanged.

[0008] As a further solution of the present invention, the discharging mechanism includes an extruder, which is fixedly connected above the U-shaped pot. A plurality of discharging holes arranged in a circumferential array are vertically opened at the lower end of the extruder corresponding to the upper end position between the inclined section and the U-shaped mounting plate. Cutting blades are arranged on the sides of the discharging holes. A stepping motor is fixedly arranged at the central position of the extruder, and the plurality of cutting blades are fixedly connected to the output shaft of the stepping motor together.

[0009] As a further solution of the present invention, a plurality of partitions arranged in a circumferential array around the central axis of the U-shaped pot are fixedly connected between the inner wall of the U-shaped pot and the U-shaped mounting plate.

[0010] As a further solution of the present invention, mounting grooves are vertically penetrated at the middle positions of the U-shaped mounting plate adjacent to the partitions, and conveyor belts are vertically arranged at the mounting grooves, and the pushing mechanism is arranged on the conveyor belts.

[0011] As a further solution of the present invention, the conveyor belt includes a synchronous pulley, which is arranged above the U-shaped mounting plate. An inner liner is fixedly connected inside the U-shaped mounting plate. The synchronous pulley is connected with a synchronous belt in a transmission manner, and the synchronous belt is slidably connected to the lower end of the inner liner. The synchronous pulley is externally connected with a driving mechanism.

[0012] As a further solution of the present invention, the pushing mechanism includes a bracket, which is fixedly connected to the belt surface of the synchronous belt. The bracket is elastically rotatably connected with a connecting block through a torsion spring. The connecting block is fixedly connected with a filter plate, and the filter plate can be telescopic and keep in contact with the inner wall of the U-shaped pot, the side wall of the U-shaped mounting plate and the partitions.

[0013] As a further solution of the present invention, a plurality of communication holes are opened in the U-shaped pot of the inclined section. The communication holes communicate the internal space of the U-shaped pot in the inclined section with the internal space of the U-shaped pot at the upper end of the inclined section. A heater is externally connected to the communication holes, and the heater is used for heating the hot oil.

[0014] As a further solution of the present invention, the filter plate includes a plurality of first elastic telescopic rods arranged in a circumferential array with the central axis of the U-shaped pot as the axis and the included angle between two adjacent partitions as the array angle. The first elastic telescopic rod at the middle position is fixedly connected to the end of the connecting block. The side walls of two adjacent first elastic telescopic rods are commonly connected with second elastic telescopic rods, and the ends of the second elastic telescopic rods are elastically rotatably connected to the side walls of the corresponding first elastic telescopic rods.

[0015] As a further solution of the present invention, the end of the first elastic telescopic rod fixedly connected to the end of the connecting block is vertically elastically slidably connected with a clamping block. A connecting groove is vertically opened at the upper end of the clamping block. A steel wire is fixedly connected to the bottom of the connecting groove. The steel wire is fixedly connected with a spring. The spring is fixedly connected to the upper right side of the upper end of the first elastic telescopic rod. The upper end of the vertical section is fixedly connected with a clamping ring capable of being engaged with the clamping block.

[0016] Fish tofu processing technology, the method is as follows:

[0017] S1. During operation, the discharging mechanism drops an appropriate amount of independent fish tofu pre-products into the U-shaped pot filled with hot oil above the U-shaped pot.

[0018] S2. Then, driven by the pushing mechanism, during the process of the fish tofu pre-products moving along the inner wall of the U-shaped pot, they are fried in hot oil at different positions.

[0019] S3. Finally, it is discharged through the feeding channel at the center of the U-shaped pot.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In the present invention, the pushing mechanism drives the fish tofu to move along the inner wall of the U-shaped pot, so that the hot oil directly contacted by the fish tofu is constantly changing. As a result, the temperature of the hot oil directly contacted by the fish tofu pre-products can be kept uniform and is not prone to a rapid decline. Compared with the traditional frying method, it no longer simply relies on the mutual exchange of hot oil to maintain the stability of the oil temperature. Therefore, during the frying process of the fish tofu, the amount of hot oil input into the U-shaped pot to maintain the stability of the hot oil temperature directly contacted by the fish tofu pre-products is reduced.

[0022] 2. In the present invention, according to the fact that when the fish tofu pre-products just enter the U-shaped pot, the temperature of the fish tofu pre-products is the lowest and the water content is the highest. At this time, the fish tofu pre-products consume the most heat. Then, as the frying progresses, the temperature of the fish tofu pre-products gradually increases, the water content gradually decreases, and the heat consumption gradually decreases (corresponding to the inclined section), until it stabilizes. After stabilization, the fish tofu pre-products only need to maintain a certain stability for the coking reaction (corresponding to the arc section and the vertical section). Therefore, by gradually reducing the cross-sectional area of the U-shaped pot at the inclined section, the arc section and the vertical section until it remains unchanged after reaching the arc section, the volume of the U-shaped pot is reduced, and the input amount of hot oil is reduced.

[0023] 3. In the present invention, by horizontally distributing each discharging hole, each fish tofu pre-product is discharged horizontally, further preventing the fish tofu pre-products from contacting and squeezing each other, and avoiding the fish tofu pre-products from sticking to each other before frying and solidifying, resulting in poor finished products.

Detailed implementation manners

[0032] Please refer to Figures 1-6 , the present invention provides a technical solution: a fish tofu processing device, characterized in that: it includes a U-shaped pot 11, a U-shaped mounting plate 12, a transmission mechanism, a discharge mechanism and a pusher mechanism, the discharge mechanism is arranged above the U-shaped pot 11 for inputting prefabricated materials into the U-shaped pot 11, a blanking channel 13 is formed in the center of the U-shaped pot 11 surrounded by the U-shaped pot 11 for discharging finished products, the U-shaped mounting plate 12 is arranged in the U-shaped pot 11, the transmission mechanism is arranged in the U-shaped mounting plate 12, the pusher mechanism is arranged on the transmission mechanism, the pusher mechanism is used to push the prefabricated materials from the upper end of the U-shaped pot 11 along the inner wall of the U-shaped pot 11 into the center of the U-shaped pot 11 for discharging, and hot oil is injected into the U-shaped pot 11 and the hot oil can be heated.

[0033] During operation, the discharging mechanism drops an appropriate amount of independent fish tofu pre-products into the U-shaped pot 11 filled with hot oil. Then, driven by the pushing mechanism, the fish tofu pre-products move along the inner wall of the U-shaped pot 11 through the hot oil in the U-shaped pot 11 and finally are discharged through the blanking channel 13 at the center of the U-shaped pot 11. During the process of the fish tofu pre-products moving along the inner wall of the U-shaped pot 11, they are fried in hot oil at different positions, so that the hot oil temperature in direct contact with the fish tofu pre-products can be kept at a uniform temperature and is not prone to a rapid decrease phenomenon. Furthermore, during the frying process of the fish tofu, the amount of hot oil put into the U-shaped pot 11 to maintain the stability of the hot oil temperature in direct contact with the fish tofu pre-products is reduced.

[0034] In the present invention, the pushing mechanism drives the fish tofu to move along the inner wall of the U-shaped pot 11, so that the hot oil in direct contact with the fish tofu continuously changes. As a result, the hot oil temperature in direct contact with the fish tofu pre-products can be kept at a uniform temperature and is not prone to a rapid decrease phenomenon. Compared with the traditional frying method, it no longer simply relies on the mutual exchange of hot oil to maintain the oil temperature stability. Furthermore, during the frying process of the fish tofu, the amount of hot oil put into the U-shaped pot 11 to maintain the stability of the hot oil temperature in direct contact with the fish tofu pre-products is reduced.

[0035] As a further solution of the present invention, the inner wall of the U-shaped pot 11 includes an arc section 21 at the bottom. The U-shaped mounting plate 12 is arranged directly above the arc section 21. One side of the arc section 21 away from the center of the U-shaped pot 11 is connected with an inclined section 22. The vertical distance from the inclined section 22 to the U-shaped mounting plate 12 gradually increases from bottom to top. One side of the arc section 21 close to the center of the U-shaped pot 11 is connected with a vertical section 23. The vertical distances from the arc section 21 and the vertical section 23 to the U-shaped mounting plate 12 are equal and unchanged.

[0036] During operation, the fish tofu pre-products dropped into the U-shaped pot 11 by the discharging mechanism enter the U-shaped pot 11 between the inclined section 22 and the U-shaped mounting plate 12. Then, driven by the pushing mechanism, the fish tofu pre-products are fried successively through the inclined section 22, the arc section 21, and the vertical section 23 from the upper end of the inclined section 22, and finally enter the blanking channel 13 and are discharged from the upper end of the vertical section 23. During this process, the cross-sectional area of the U-shaped pot 11 through which the fish tofu pre-products pass gradually decreases until it remains unchanged after reaching the arc section 21. Correspondingly, when the fish tofu pre-products first enter the U-shaped pot 11, the temperature of the fish tofu pre-products is the lowest and the water content is the highest. At this time, the fish tofu pre-products consume the most heat. Then, with continuous frying, the temperature of the fish tofu pre-products gradually increases, the water content gradually decreases, and the heat consumption gradually decreases (corresponding to the inclined section 22) until it stabilizes. After stabilization, the fish tofu pre-products only need to maintain a certain stability for the coking reaction (corresponding to the arc section 21 and the vertical section 23). Furthermore, by gradually reducing the cross-sectional area of the U-shaped pot 11 at the inclined section 22, the arc section 21, and the vertical section 23 until it remains unchanged after reaching the arc section 21, the volume of the U-shaped pot 11 is reduced, and the input amount of hot oil is reduced.

[0037] According to the present invention, when the fish tofu pre-products first enter the U-shaped pot 11, the temperature of the fish tofu pre-products is the lowest and the water content is the highest. At this time, the fish tofu pre-products consume the most heat. Then, with continuous frying, the temperature of the fish tofu pre-products gradually increases, the water content gradually decreases, and the heat consumption gradually decreases (corresponding to the inclined section 22) until it stabilizes. After stabilization, the fish tofu pre-products only need to maintain a certain stability for the coking reaction (corresponding to the arc section 21 and the vertical section 23). Furthermore, by gradually reducing the cross-sectional area of the U-shaped pot 11 at the inclined section 22, the arc section 21, and the vertical section 23 until it remains unchanged after reaching the arc section 21, the volume of the U-shaped pot 11 is reduced, and the input amount of hot oil is reduced.

[0038] As a further solution of the present invention, the discharging mechanism includes an extruder 31, the extruder 31 is fixedly connected above the U-shaped pot 11, a plurality of discharging holes 32 arranged in a circumferential array are vertically opened at the lower end of the extruder 31 corresponding to the upper end position between the inclined section 22 and the U-shaped mounting plate 12, cutting blades 33 are arranged on the sides of the discharging holes 32, a stepping motor 34 is fixedly arranged at the central position of the extruder 31, and the plurality of cutting blades 33 are fixedly connected to the output shaft of the stepping motor 34 together.

[0039] During operation, the stepper motor 34 is started, and the stepper motor 34 drives the cutting piece 33 to rotate (before the stepper motor 34 rotates, the extruder 31 first extrude a section of fish tofu raw material through the discharge hole 32), and the cutting piece 33 cuts the fish tofu raw material extruded from the discharge hole 32 to obtain a fish tofu preformed product, and the fish tofu preformed product falls vertically into the U-shaped pot 11 under the action of gravity, and in the process of falling, since each discharge hole 32 is horizontally distributed, each fish tofu preformed product is discharged horizontally, and further, the fish tofu preformed products will not contact and squeeze each other, so as to avoid the fish tofu preformed products sticking to each other before frying and curing, resulting in a defective finished product.

[0040] The present invention distributes the discharge holes 32 horizontally, so that the fish tofu preformed products are discharged horizontally, and further prevent the fish tofu preformed products from contacting and squeezing each other, thereby preventing the fish tofu preformed products from sticking to each other before frying and curing, resulting in defective finished products.

[0041] As a further solution of the present invention, a plurality of partitions 41 arranged in a circular array around the central axis of the U-shaped pot 11 are fixedly connected between the inner wall of the U-shaped pot 11 and the U-shaped mounting plate 12 .

[0042] During operation, each partition 41 divides the U-shaped pot 11 into different flow channels, so that the fish tofu preforms enter different flow channels for frying, further avoiding too many fish tofu preforms in the same open space, resulting in accumulation and affecting the processing quality.

[0043] As a further solution of the present invention, the U-shaped mounting plate 12 is provided with a mounting groove 51 in the middle of the adjacent partitions 41 , a conveyor belt is vertically arranged at the mounting groove 51 , and the pushing mechanism is arranged on the conveyor belt.

[0044] During operation, the conveyor belt rotates and drives the pushing mechanism to move around the U-shaped mounting plate 12 , thereby driving the fish tofu preform to move in the U-shaped pot 11 .

[0045] As a further solution of the present invention, the conveyor belt includes a synchronous wheel 61, which is arranged above the U-shaped mounting plate 12, and an inner liner 62 is fixedly connected to the U-shaped mounting plate 12. The synchronous wheel 61 is transmission-connected to a synchronous belt 63, and the synchronous belt 63 is slidingly connected to the lower end of the inner liner 62. The synchronous wheel 61 is externally connected to a driving mechanism.

[0046] During operation, the driving mechanism drives the synchronous wheel 61 to rotate, and then drives the pushing mechanism to move through the synchronous belt 63. The lower end of the inner liner 62 expands the synchronous belt 63. At the same time, the inner liner 62 can fill the internal space of the U-shaped mounting plate 12, reduce the internal volume of the U-shaped mounting plate 12, and thus reduce the input amount of hot oil.

[0047] In the present invention, an inner tank 62 replaces a supporting wheel of the synchronous belt 63. Meanwhile, the inner tank 62 can fill the internal space of the U-shaped mounting plate 12, reducing the internal volume of the U-shaped mounting plate 12, and thus reducing the input amount of hot oil.

[0048] As a further solution of the present invention, the pusher mechanism includes a bracket 71, which is fixedly connected to the belt surface of the synchronous belt 63. The bracket 71 is elastically rotatably connected to a connecting block 72 through a torsion spring. The connecting block 72 is fixedly connected to a filter plate, and the filter plate can be telescoped and kept in contact with the inner wall of the U-shaped pot 11, the side wall of the U-shaped mounting plate 12, and the partition plate 41.

[0049] During operation, the filter plate remains in a state of being in contact with the inner wall of the U-shaped pot 11, the side wall of the U-shaped mounting plate 12, and the partition plate 41, driving the fish tofu preform to pass through the hot oil in the U-shaped pot 11 along the inner wall of the U-shaped pot 11, and finally discharging at the blanking channel 13 at the center of the U-shaped pot 11. For the convenience of demonstrating and describing the invention solution, only one filter plate is provided on a single synchronous belt 63 in the present invention. In actual equipment use, multiple filter plates can be provided on a single synchronous belt 63, enabling the hot oil in various parts of the entire U-shaped pot 11 to simultaneously process fish tofu preforms in different frying states.

[0050] As a further solution of the present invention, the U-shaped pot 11 in the inclined section 22 is provided with a plurality of communication holes 81. The communication holes 81 connect the internal space of the U-shaped pot 11 in the inclined section 22 with the internal space of the U-shaped pot 11 at the upper end of the inclined section 22. A heater is connected to the outside of the communication holes 81, and the heater is used to heat the hot oil.

[0051] During operation, as the filter plate pushes the fish tofu preform downward along the inclined section 22, it will squeeze the hot oil downward, further increasing the pressure of the hot oil in the pushing direction of the filter plate. Further, a pressure difference is generated with the hot oil in the internal space of the U-shaped pot 11 at the upper end of the inclined section 22. The hot oil in the pushing direction of the filter plate passes through the communication holes 81 and is heated by the heater in the communication holes 81, and then flows into the upper end of the U-shaped pot 11, further enabling the hot oil at the upper end of the U-shaped pot 11 where the heat consumption is the largest to maintain a high temperature for quickly frying and shaping the fish tofu preform.

[0052] In the present invention, the hot oil in the pushing direction of the filter plate passes through the communication holes 81 and is heated by the heater in the communication holes 81, and then flows into the upper end of the U-shaped pot 11, further enabling the hot oil at the upper end of the U-shaped pot 11 where the heat consumption is the largest to maintain a high temperature for quickly frying and shaping the fish tofu preform.

[0053] As a further solution of the present invention, the filter plate includes a plurality of first elastic telescopic rods 91 arranged in a circumferential array with the central axis of the U-shaped pot 11 as the axis and the included angle between two adjacent partition plates 41 as the array angle. The first elastic telescopic rod 91 at the middle position is fixedly connected to the end of the connecting block 72. The side walls of two adjacent first elastic telescopic rods 91 are jointly connected with a second elastic telescopic rod 92, and the ends of the second elastic telescopic rods 92 are elastically and rotatably connected to the side walls of the corresponding first elastic telescopic rods 91.

[0054] During operation, during the frying process of the fish tofu prefabricated product, a large amount of water vapor will be generated (especially when the fish tofu prefabricated product just enters the U-shaped pot 11). During the telescopic process of the filter plate obtained by splicing the rod bodies, there are no dead corners, and at the same time, it can maintain good permeability to water vapor, and finally it is not easy to adhere to fish tofu residues.

[0055] As a further solution of the present invention, a clamping block 101 is vertically and elastically slidably connected to the end of the first elastic telescopic rod 91 fixedly connected to the end of the connecting block 72. A connecting groove 102 is vertically opened at the upper end of the clamping block 101. A steel wire 103 is fixedly connected to the bottom of the connecting groove 102. The steel wire 103 is fixedly connected with a spring 104, and the spring 104 is fixedly connected to the upper right side of the upper end of the first elastic telescopic rod 91. A clamping ring 105 that can be engaged with the clamping block 101 is fixedly connected to the upper end of the vertical section 23.

[0056] During operation, as the filter plate moves to the clamping ring 105, the clamping block 101 engages with the clamping ring 105, so that the end of the filter plate far from the synchronous belt 63 stops at the clamping ring 105. Then, as the synchronous belt 63 continues to rotate, the end of the filter plate close to the synchronous belt 63 moves upward, so that the filter plate overcomes the torsional spring force between the bracket 71 and the connecting block 72, the filter plate tilts and dumps the fish tofu on the filter plate into the blanking channel 13 for discharge. Finally, as the end of the filter plate close to the synchronous belt 63 continues to move upward, the first elastic telescopic rod 91 extends, the spring 104 extends, and the spring 104 pulls the clamping block 101 through the steel wire 103, so that the clamping block 101 slides relative to the end of the first elastic telescopic rod 91 and disengages from the clamping ring 105, thereby enabling the filter plate to disengage from the clamping ring 105.

[0057] The fish tofu processing process is as follows:

[0058] S1. During operation, the discharging mechanism drops an appropriate amount of independent fish tofu prefabricated products into the U-shaped pot 11 above the U-shaped pot 11 filled with hot oil;

[0059] S2. Then, driven by the pushing mechanism, during the process of the fish tofu prefabricated product moving along the inner wall of the U-shaped pot 11, it is fried by hot oil at different positions;

[0060] S3. Finally, it is discharged through the blanking channel 13 at the center of the U-shaped pot 11.
