[0002] The nutrition of soy products is mainly reflected in their rich protein content. The essential amino acids contained in soy products are similar to animal proteins, and they also contain minerals such as calcium, phosphorus, and iron needed by the human body, as well as vitamins B1, B2, and cellulose. However, soy products do not contain cholesterol. Therefore, it is recommended that patients with obesity, arteriosclerosis, hyperlipidemia, hypertension, coronary heart disease, etc. eat more beans and soy products. For the healthy population, it is not advisable to have a single source of nutrition, and soy products can be used as one of the sources of protein. Soy products are an important part of a balanced diet.

[0003] Currently, in a production and processing method of hand-made black tofu with firewood on the market, such as the patent number CN118575920A, during the production and processing, the cooked soy milk is exhausted by repeatedly draining and exhausting. Such a method not only has a slow exhaust speed, but also has a cumbersome processing procedure and cannot improve the continuity of production well. Therefore, improving the continuity of production and the exhaust speed are the existing problems. Summary of the Invention

[0042] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0043] A production process for compacting hand-made black tofu with firewood specifically includes the following steps: S1, select high-quality soybeans and black sesame seeds, and remove the blackened or other moldy or other inferior soybeans and inferior black sesame seeds; it is also necessary to prepare defoaming agent, magnesium chloride, tofu boxes and covering films;

[0045] S3, while step S2 is being carried out, stir-fry the selected high-quality black sesame seeds, and crush the stir-fried black sesame seeds into a paste for preparation;

[0046] S4, grind the soybeans processed in step S2, and filter the ground pulp to separate the soymilk part. An appropriate amount of defoaming agent needs to be added during the grinding process;

[0047] S5. Boil the soymilk filtered in step S4. The boiling temperature needs to reach above 95°C, and add defoamer again during the boiling process.

[0048] S6. Perform secondary filtration and separation on the soymilk after boiling in step S5 to remove residues and obtain cooked soymilk. Add a small amount of magnesium chloride and a small amount of pasty black sesame seeds to the obtained cooked soymilk for coagulation by adding coagulant.

[0049] S7. Rotate the cooked soymilk obtained in step S6 for preliminary exhaust. The specific rotation exhaust method is as follows: Import the obtained cooked soymilk into the rotating device 1. The rotating device 1 is configured to gradually reduce the thickness of the cooked soymilk on the rotating cylinder wall after importing the cooked soymilk, thereby exhausting the gas in the soymilk liquid, and finally discharging it along the cylinder wall of the rotating device 1.

[0050] S8. Import the cooked soymilk preliminarily exhausted in step S7 into the secondary exhaust device 2. The secondary exhaust device 2 includes a casting area 3. The casting area 3 is composed of two side baffles 30 and a moving plate 31 arranged between the two side baffles 30. Both moving plates 31 are connected to a regulator 4. Start the regulator 4 to drive the moving plate 31. The two moving plates 31 are in contact with the two side baffles 30 to obtain the casting area 3. The regulator 4 is configured to be able to move the moving plate 31 in real time as the casting pressure increases.

[0051] First, export the cooked soymilk from the rotating device 1, and then pour the cooked soymilk in the casting area 3. Set the casting value to ensure that the volume of the cast cooked soymilk is between 3 / 5 and 4 / 5 of the volume of the casting area 3.

[0052] Record the moving position of the moving plate 31 after being subjected to the casting pressure. Record the initial position of the moving plate 31 through the displacement sensor provided on the regulator 4, and then record the position of the moving plate 31 after casting the cooked soymilk. Due to the control of the regulator 4, the moving plate 31 after displacement will maintain the position after displacement, and until the moving plate 31 no longer receives a force, the pressure detector in the regulator 4 detects whether the pressure is at a constant value.

[0053] After the pressure is constant, the regulator 4 controls the moving plate 31 to reset by pushing the moving plate 31 until the moving plate 31 returns to the initial position.

[0058] S12. Pack the packaged tofu boxes into cases, conduct leak-proof detection, and then store the cased tofu in a cold storage with a temperature between 0°C and 4°C.

[0059] S13. Repeat steps S1 - S12.

[0060] The basic production process adopted in the present invention is basically the same as that in the patent literature of the background technology. The main difference is that for the exhaust treatment of the liquid material, the present invention adopts the rotating operation of the rotating device 1. By gradually reducing the thickness of the liquid material and through the change of centrifugal force, the bubbles in the cooked soy milk are removed. And during the pouring of the blank, the pouring area 3 is adjusted in real time through the regulator 4 to form a lateral buffer after pouring the cooked soy milk and to perform multiple pouring compaction operations, thereby reducing the generation of bubbles during the pouring of the cooked soy milk. And through the real-time adjustment of the pouring area 3 by the rotating device 1 and the regulator 4, the compaction effect of pouring is greatly improved, making the tofu more compact and greatly enhancing the practicability.

[0061] In the embodiment of the present invention, in addition to adopting the basic firewood manual process, the exhaust method of the rotating device 1 and the specific pouring equipment are also adopted to enable the cooked tofu to reduce the generation of bubbles. The two complement each other, so as to realize the solidification of the soy milk into tofu in a compact manner, change the traditional exhaust method, and further avoid the generation of bubbles during the pouring process.

[0062] Furthermore, the rotary device 1 includes a main cylinder body 10, a feed inlet 101 and a discharge outlet 102 provided on the main cylinder body 10, mechanical seals provided at both ends of the main cylinder body 10, and a rotary motor 11 for driving the rotation of the main cylinder body 10. A thickness detector for monitoring the real-time thickness of the soymilk liquid is provided inside the main cylinder body 10, and a flow detector for monitoring the real-time flow rate of the soymilk liquid is further provided at the feed inlet 101 of the main cylinder body 10. In order to improve the exhaust operation of the cooked tofu, the rotary device 1 is set to include the main cylinder body 10, the feed inlet 101 and the discharge outlet 102 provided on the main cylinder body 10, the mechanical seals provided at both ends of the main cylinder body 10, and the rotary motor 11 for driving the rotation of the main cylinder body 10. A thickness detector for monitoring the real-time thickness of the soymilk liquid is provided inside the main cylinder body 10, and a flow detector for monitoring the real-time flow rate of the soymilk liquid is further provided at the feed inlet 101 of the main cylinder body 10. And through the provided thickness detector and flow detector, the thickness and flow rate of the soymilk liquid in the main cylinder body 10 are monitored in real time, so as to realize the degassing of the cooked soymilk, and further improve the compactness effect of the tofu after pouring the billet, and have a better taste.

[0063] Furthermore, the specific exhaust method of the rotary device 1 is as follows: the monitoring parameters of the thickness detector and the flow detector are received in real time, and the monitoring parameters are composed of the thickness of the liquid on the inner surface of the cylinder sent by the thickness detector and the liquid flow rate at the feed inlet 101 sent by the flow detector; and preset parameters are set for the achieved thickness;

[0064] Then, a relative parameter ratio H is calculated according to the monitoring parameters and the preset parameters monitored by the thickness detector. The relative parameter ratio H is used to represent the deviation of the monitoring parameters from the preset parameter difference, and the relative parameter ratio H = (current liquid thickness - target liquid thickness) / target liquid thickness;

[0065] Finally, based on the relative parameter ratio, the rotation speed of the drive motor is adjusted to reduce the difference between the monitoring parameters and the preset parameters.

[0066] Regarding the control of the above-mentioned rotary exhaust, first of all, the rotary exhaust has centrifugal force exhaust and gradually thins the thickness of the soymilk liquid, so that the bubbles can gradually form an exhaust operation as the soymilk liquid thins. And the parameters monitored by the thickness detector are compared with the preset parameters, and the relative parameter ratio is calculated, and then the rotation speed of the drive motor is adjusted, so as to reduce the difference between the monitored thickness parameter and the preset thickness parameter, so as to realize the control of the bubble discharge in the cooked soymilk, the monitoring data is stable, and the practicability is also greatly improved. At the same time, the processing speed is also greatly improved.

[0067] Moreover, in the embodiment of the present invention, a flow detector for the liquid material is further added, which can ensure the continuity of exhaust by real-time monitoring of the flow rate, greatly improving the practicability.

The buffer part 22 includes a first inner pushing plate 220 for driving the pushing air chamber 21 to form a pressure change, a second inner pushing plate 222 arranged in the driving air chamber 23 and connected to the first inner pushing plate 220 through a connecting rod 221, and a buffer spring 24 arranged between the first inner pushing plate 220 and the driving air chamber 23 and sleeved outside the connecting rod 221.

[0069] The present invention is further configured as follows: the driving air chamber 23 includes a regulating air port 230 and a driving air port 231, the driving air port 231 is connected to a driving air pump 232 and an electromagnetic on-off valve 233 for regulating the on-off of the driving air port 231, and an electromagnetic one-way valve 234 is provided on the regulating air hole, and the electromagnetic one-way valve 234 is configured such that when the electromagnetic on-off valve 233 is opened, the electromagnetic one-way valve 234 is in a closed state; when the electromagnetic on-off valve 233 is closed, the electromagnetic one-way valve 234 is in a one-way air outlet state, in order to ensure that during the casting process, the casting process can be allowed to The cooked soy milk in the area 3 can be more compacted, and the generation of bubbles in the pouring process is reduced. The regulator 4 is set to include a driving part 20 and a pushing air chamber 21, and the pushing air chamber 21 is transmission-connected to the moving plate 31. The driving part 20 includes a driving air chamber 23 connected to the pushing air chamber 21 and a buffer part 22 arranged between the pushing air chamber 21 and the driving air chamber 23. The present invention uses the driving part 20 and the pushing air chamber 21 as the main regulating parts. Because the pushing air chamber 21 and the moving plate 31 are connected, the moving plate 31 will push the pushing air chamber 23 when it is subjected to force. 1 forms pressure, and the buffer part 22 includes a first inner push plate 220 for driving the push air chamber 21 to form a pressure change, a second inner push plate 222 arranged in the driving air chamber 23 and connected to the first inner push plate 220 through a connecting rod 221, and a buffer spring 24 arranged between the first inner push plate 220 and the driving air chamber 23 and sleeved outside the connecting rod 221, so that a first buffer is formed by the buffer spring 24, and in the present invention, the driving air chamber 23 includes an adjusting air port 230 and a driving air port 231, and the driving air port 231 is connected to a driving air pump 232 and a buffer spring 24 for driving the driving air chamber 23. The electromagnetic on-off valve 233 for on-off regulation of the air port 231 is provided with an electromagnetic one-way valve 234 on the regulating air hole. The electromagnetic one-way valve 234 is configured so that when the electromagnetic on-off valve 233 is opened, the electromagnetic one-way valve 234 is in a closed state; when the electromagnetic on-off valve 233 is closed, the electromagnetic one-way valve 234 is in a one-way air outlet state, so that after closing the electromagnetic on-off valve 233, the electromagnetic one-way valve 234 can maintain a continuous air outlet state, thereby maintaining the position of the movable plate 31, achieving a lateral buffering effect when pouring the billet, reducing the generation of bubbles in the cooked soy milk, and greatly improving the practicality.

[0070] Furthermore, the specific adjustment method of the regulator 4 is as follows: the initial position of the moving plate 31 is recorded by the displacement sensor;

[0071] When the cooked soy milk is led out from the rotating device 1 to the casting area 3, the movable plate 31 is pressed to move toward the driving air chamber 23, and the regulating air port 230 of the driving air chamber 23 is exhausted. After the air pressure is stabilized, the movable plate 31 stops moving.

[0072] After the pressure becomes constant, the driving air chamber 23 of the regulator 4 increases the air pressure in the driving air chamber 23 through the driving air pump 232, pushing the second inner pushing plate 222 to push the moving plate 31 to reset, until the moving plate 31 returns to its initial position by pushing the moving plate 31;

[0073] Repeat the action of pouring the cooked soy milk on the blank, and repeat the air pressure adjustment action for the driving air chamber 23 until the pouring of the blank is completed.

[0074] In the embodiment of the present invention, by pouring the cooked soy milk after passing through the rotating device 1, and as the pressure continuously increases, the pressure on the moving plate 31 can be adjusted. And as the pouring thickness of the blank continuously increases, the formed pressure will also gradually increase. During reset, the air pressure in the driving air chamber 23 can be gradually adjusted through the driving air pump 232, so as to ensure continuous buffering during the pouring process of the blank and reduce the generation of bubbles due to too fast pouring speed.
