Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and specifically relates to a soybean steaming device. Background Technology

[0002] Soy protein is a high-quality plant protein that is widely used in food, feed and other fields. Heat treatment can loosen the protein molecular structure, expose enzyme cleavage sites and improve digestion and absorption efficiency; however, high temperature or improper treatment can cause excessive denaturation of the protein, forming insoluble substances and reducing its nutritional value.

[0003] To eliminate the activity of anti-nutritional factors in soybeans, high-temperature treatment at 120℃-130℃ is generally used. Currently, the industry commonly uses heating tubes, transferring heat to the soybeans via hot water. However, due to water's high specific heat capacity, significant heat consumption is required for heating, and the heat transfer is gradient-dependent, resulting in low heat utilization efficiency, high energy consumption, and high costs. Therefore, developing new heat treatment technologies and equipment that can effectively reduce the activity of anti-nutritional factors while minimizing energy consumption and ensuring the nutritional quality of soybean protein has become an urgent problem for the industry.

The embodiments of this utility model will now be described based on its overall structure.

[0025] See Figure 1 The soybean steaming device includes a steam tank 1, with an inlet 2 and a steam outlet 3 at the top and an outlet 4 at the bottom. A material inlet sealing mechanism 5 is connected to the inlet 2 and the outlet 4. An inner steam liner 6 is connected inside the steam tank 1, and a stirring mechanism 7 is installed in the inner steam liner 6. A steam drainage zone 8 is formed between the bottom of the inner steam liner 6 and the steam tank 1. A through hole 61 is provided at the bottom of the inner steam liner 6, communicating with the steam drainage zone 8. A steam drainage pipe 9 and a pressure relief pipe 10 are connected to the steam tank 1, and the steam drainage pipe 9 and the pressure relief pipe 10 communicate with the steam drainage zone 8.

[0026] The steam port 3 is connected to a steam pipe 15, which is connected to a steam generator. A steam pressure gauge is installed on the steam pipe 15.

[0027] A steam generator produces steam, which enters the steam liner 6 through steam pipe 15 and steam port 3. A steam pressure gauge on steam pipe 15 displays the current pressure value in real time, enabling monitoring of the pressure status within the steam liner 6. Steam is used in the steam liner 6 to perform detoxification heat treatment on soybeans. Steam's convective heat transfer coefficient is much higher than water's, and steam releases a large amount of latent heat of vaporization when it liquefies upon cooling. Therefore, when steam comes into contact with soybeans, it can quickly transfer a large amount of heat to the material, shortening the heating time. Because of this rapid heat treatment, when large batches of soybeans require heat treatment, shortening the heating time reduces electricity consumption, thereby lowering energy consumption.

[0028] The steam tank 1 is equipped with a pressure relief valve, which is installed on the top of the steam tank 1. The pressure relief valve is used to depressurize the steam tank 1 and reduce the steam tank 1 to atmospheric pressure.

[0029] See Figure 1 The steam tank 1 is connected to an ethanol-mixed steam nozzle 13 and an acetic acid-mixed steam nozzle 14. The ethanol-mixed steam nozzle 13 is used to spray ethanol-containing steam into the steam tank 6, and the acetic acid-mixed steam nozzle 14 is used to spray acetic acid-containing steam into the steam tank 6.

[0030] In the process of detoxifying soybeans, high-pressure steam is first used to heat the soybeans to increase the concentration of trypsin inhibitors and the removal effect of purines. Then, ethanol and acetic acid are added under low pressure to further enhance the removal effect of trypsin inhibitors and purines.

[0031] Therefore, this embodiment also provides a method for detoxifying soybeans using the soybean steaming device described above, as follows:

[0032] Soybeans to be cooked are placed in the steam liner 6 of steam tank 1, and high-pressure steam is introduced into steam tank 1 through steam pipe 15. After the high-pressure steam has been introduced for a predetermined time, the pressure relief valve at the top of steam tank 1 is used to depressurize the steam tank 1, reducing it to atmospheric pressure. Then, ethanol-mixed steam is introduced into steam tank 1 through an ethanol-mixed steam nozzle, and the mixture is treated under low pressure for a predetermined time. After the ethanol-mixed steam has been treated under low pressure for a predetermined time, acetic acid-mixed steam is introduced into steam tank 1 through an acetic acid-mixed steam nozzle, and the mixture is treated under low pressure for a predetermined time. After the acetic acid-mixed steam has been treated under low pressure for a predetermined time, steam tank 1 is reduced to atmospheric pressure, and then ethanol-mixed steam is introduced into steam tank 1 again through an ethanol-mixed steam nozzle, and the mixture is treated under low pressure for a predetermined time. Finally, the pressure is released.

[0033] See Figure 3 A steam trap valve 11 is connected to the steam trap pipe 9, and a pressure relief valve 12 is connected to the pressure relief pipe 10. During the steam cooking process of soybeans, high-temperature condensate is generated after heat exchange between the steam and soybeans. The bottom of the tank is the lowest point of the entire container, providing a natural collection place for the condensate. A through hole 61 is provided at the bottom of the steam inner liner 6, through which the high-temperature condensate generated during the cooking process enters the steam trap zone 8. A steam trap pipe 9 is provided on the steam trap zone 8 to store the high-temperature condensate generated during the heating process. During the heating process, the steam trap valve 11 is 0% open, and only after heating is completed is the steam trap valve 11 opened to drain the water from the steam trap zone 8 and the steam trap pipe 9.

[0034] To ensure that the pressure in steam tank 1 does not exceed its design working pressure during heating, the opening degree of the pressure relief valve at the top of steam tank 1 can be 1% to 3%, allowing steam tank 1 to meet high-pressure conditions while preventing the pressure from exceeding its design working pressure. Regarding the pressure relief pipe 10 on the steam condensate drain area 8, since steam condensate drain area 8 is mainly used to store high-temperature condensate, it also has a certain pressure, but its pressure is not as high as that in the inner steam liner 6, and normally does not affect the heat treatment of the tank. However, for the safety of the tank, the pressure relief pipe 10 is installed in steam condensate drain area 8 to reduce the pressure in steam condensate drain area 8. Since the pressure in steam condensate drain area 8 usually does not exceed the pressure in the inner steam liner 6, the opening degree of the pressure relief valve 12 on steam condensate drain area 8 is usually 0% during heat treatment of the tank.

[0035] In this embodiment, the steam port 3 on the steam tank 1 is located at the top of the steam tank 1. In some preferred embodiments, the steam port 3 may be located in the middle of the steam tank 1.

[0036] See Figure 4The steam tank 1 is also equipped with a stirring mechanism 7. The soybeans in the area closest to the steam vent 3 come into contact with the steam first, while other areas farther away from the steam vent 3 are heated later. At this time, the stirring mechanism 7 can turn the soybeans over, preventing them from staying in the steam vent 3 all the time, breaking up local temperature differences and ensuring that each soybean is heated evenly. At the same time, stirring can further shorten the heating time.

[0037] The stirring mechanism 7 uses a low stirring speed, which allows the soybeans to be slowly turned over, preventing them from being crushed. At the same time, it can disperse the steam, ensuring that the soybeans are heated evenly.

[0038] See Figure 3 and Figure 4 The stirring mechanism 7 includes a stirring motor 71 and a stirring shaft 72 connected to the stirring motor 71. A first mounting base 73 and a second mounting base 74 are connected at the top of the steam tank 1. The first mounting base 73 and the second mounting base 74 are respectively sleeved on the outside of the stirring shaft 72. The first mounting base 73 and the second mounting base 74 are connected, and the stirring shaft 72 can rotate relative to the first mounting base 73 and the second mounting base 74.

[0039] An air seal 75 is fitted around the outside of the stirring shaft 72. Two rotating rings 76 are symmetrically arranged between the two ends of the air seal 75 and the stirring shaft 72. The end of the rotating ring 76 furthest from the air seal 75 is connected to a stationary ring 77. The two stationary rings 77 are respectively connected to the inner sides of the first mounting base 73 and the second mounting base 74. The outer side of the rotating ring 76 is connected to the inner sides of both ends of the air seal 75. A groove is provided on the inner side of the end of the rotating ring 76 furthest from the stationary ring 77, and a sealing ring 78 is provided within the groove. The inner side of the sealing ring 78 contacts the stirring shaft 72.

[0040] The sealing ring 78 is used to improve the sealing performance between the rotating ring 76 and the stirring shaft 72. The rotating ring 76 is fixedly connected to the gas seal 75 and can rotate with the stirring shaft 72. The stationary ring 77 is fixedly connected to the first mounting base 73 and the second mounting base 74 respectively, and the rotating ring 76 rotates relative to the stationary ring 77. Through the synergistic action of the rotating ring 76 and the stationary ring 77, the stirring shaft 72 is sealed to prevent gas leakage.

[0041] See Figure 2 The material inlet sealing mechanism 5 includes a base 51 connected to the steam tank 1. A connecting part 511 is provided at the upper end of the base 51. A sealing groove 5110 is provided on the connecting part 511. A pressure cap 52 is connected to the connecting part 511. An insert 521 is formed on the pressure cap 52. A sealing strip 53 is provided between the insert 521 and the sealing groove 5110. A detachable bolt 54 connects the base 51 and the pressure cap 52.

[0042] The base 51 can be integrally formed with the steam tank 1. During feeding, the pressure cap 52 is removed from the base 51, and a feeding pipe with a fabric belt is connected to one end. This fabric belt extends through the base 51 into the steam tank 1, allowing the soybean material to enter the steam liner 6. After the soybean material has entered the tank, the pressure cap 52 is connected to the base 51, and bolts 54 are used to secure the pressure cap 52 tightly to the base 51. The insert 521 can press firmly against the sealing strip 53, ensuring that the sealing strip 53 seals the contact surface between the base 51 and the pressure cap 52.

[0043] In summary, the soybean steaming device provided by this utility model uses steam to detoxify and cook soybeans, which can significantly reduce energy consumption during the soybean cooking process.
