Description

Technical Field

[0001] This utility model relates to the field of dried bean curd production technology, specifically to a soaking device for peeling soybeans. Background Technology

[0002] Tofu skin (yuba) is a traditional soy product made from soybeans. It is also known as tofu skin, tofu wrapper, or bean curd stick. Tofu skin is made by heating and boiling soy milk, which forms a thin film of protein on the surface. The film is then removed and air-dried or oven-dried. It is named for its resemblance to bamboo branches. The traditional process includes soaking soybeans, grinding them into a paste, filtering, boiling, removing the film, and drying. Modern production combines natural sun-drying with drying room technology to improve efficiency.

[0003] Currently, in the production process of dried bean curd sticks, soybeans are soaked to soften the bean skins and expand the beans, making them easier to peel. Existing soybean soaking equipment uses a motor-driven stirring mechanism to agitate the soybeans during soaking, ensuring even soaking. However, the stirring rod can easily break the soaked soybeans. Therefore, a new soaking device for peeling soybeans is proposed. This device opens the air inlet valve to allow compressed air to flow into the air collection pipe, then into the air distribution pipe, and finally out through the one-way valve at the outlet to spray out from the nozzle. This pneumatic agitation of the soaked soybeans prevents damage to the soybeans. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a soaking device for peeling soybeans. By opening the air inlet valve, compressed air flows into the air collection pipe, then into the air distribution pipe, and is sprayed out from the nozzle through the air outlet one-way valve, which pushes the soaking soybeans to tumble and stir them with pneumatic force, preventing the soybeans from breaking.

[0005] The technical solution adopted by this utility model to solve its technical problem is a soaking device for peeling soybeans, including a box body. An air inlet component is provided at the bottom of the box body. The air inlet component includes an air collecting pipe installed at the bottom of the box body through a mounting bracket. Air distribution pipes are welded at equal intervals on both sides of the air collecting pipe. An air outlet one-way valve is connected at equal intervals to the top of the air distribution pipe through a threaded groove. A nozzle is connected to the top of the air outlet one-way valve through a threaded groove.

[0006] The filter screen is fixed inside the box with bolts. Heating components are provided on both sides of the box. The heating components include stainless steel plate sleeves fixed to both sides of the box with bolts. Electric heating wires are fixed at equal intervals inside the stainless steel plate sleeves with bolts. The stainless steel plate sleeves located outside the electric heating wires are filled with magnesium oxide powder.

[0007] By adopting the above technical solution, compressed air enters the air collection pipe and flows into the air distribution pipe, and then is sprayed out from the nozzle through the one-way valve, which pushes the soybeans soaking in the box to roll. The magnesium oxide powder plays the role of insulation and heat conduction, and conducts the temperature of the electric heating wire to the stainless steel plate sleeve.

[0008] Specifically, the box body has a discharge chute extending through the outer side of one end of the filter screen, and a sealing door is hinged to the side of the box body on the side of the discharge chute.

[0009] Specifically, the end of the gas collection pipe located on the outside of the housing is connected to an air inlet valve via a threaded groove.

[0010] Specifically, the end of the box located at the top of the air inlet valve is connected to a water inlet valve via a pipe, and the end of the box located at the bottom of the discharge trough is connected to a water outlet valve via a pipe.

[0011] Specifically, a thermostat is mounted on one end of the housing via a mounting base. The detection end of the thermostat is located inside the housing, and the current output end of the thermostat is electrically connected to the current input end of the heating wire via a power cord.

[0012] Specifically, the enclosure has an access door hinged to one side of the bottom of the thermostat.

[0013] The beneficial effects of this utility model are:

[0014] (1) The soybean peeling soaking device described in this utility model allows personnel to open the air inlet valve at regular intervals when the soybeans are soaking in the box, so that compressed air flows into the air collection pipe and is divided into the air distribution pipe, and then flows into the air outlet one-way valve and flows into the clean water through the nozzle. The gas enters the clean water and pushes the soybeans to roll, avoiding insufficient or excessive soaking of the soybeans in some areas.

[0015] (2) The soybean peeling soaking device of this utility model is used to control the heating of the electric heating wire by the temperature controller during the yellow soaking process. The water in the tank is heated by magnesium oxide powder and stainless steel plate sleeve to meet the soaking requirements of soybeans. The water outlet valve is opened to drain the soaking water in the tank. After the soaking water in the tank is drained, the soybeans fall onto the filter screen plate and are guided by the filter screen plate to roll towards the discharge trough. The sealed door can be opened to discharge the soaked soybeans. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Open the air inlet valve to allow compressed air to flow into the air collection pipe, then into the air distribution pipe, and finally out through the outlet check valve from the nozzle. This agitates the soaking soybeans, creating a pneumatic stirring effect that prevents the soybeans from breaking apart. Figure 1-4 As shown, the present invention provides a soaking device for peeling soybeans, comprising a housing 1, an air inlet assembly 2 at the bottom of the housing 1, the air inlet assembly 2 including an air collecting pipe 201 mounted on the bottom of the housing 1 via a mounting bracket, air distribution pipes 202 welded equidistantly on both sides of the air collecting pipe 201, and air outlet one-way valves 203 connected equidistantly at the top of the air distribution pipes 202 via threaded grooves, and a nozzle 204 connected to the top of the air outlet one-way valves 203 via threaded grooves;

[0024] The filter screen 3 is fixed inside the box 1 by bolts. Heating components 4 are provided on both sides inside the box 1. The heating components 4 include stainless steel plate sleeves 401 fixed to both sides inside the box 1 by bolts. Electric heating wires 402 are fixed at equal intervals inside the stainless steel plate sleeves 401 by bolts. The interior of the stainless steel plate sleeves 401 outside the electric heating wires 402 is filled with magnesium oxide powder 403.

[0025] When in use, compressed air enters the air collection pipe 201 and flows to the air distribution pipe 202. Then, it is sprayed out from the nozzle 204 through the one-way valve 203, which pushes the soybeans soaked in the box 1 to roll. The magnesium oxide powder 403 plays the role of insulation and heat conduction, and conducts the temperature of the electric heating wire 402 to the stainless steel plate sleeve 401.

[0026] For example, such as Figure 2As shown, the present invention also includes a discharge chute 5 extending through the outer side of the box body 1 at one end of the filter screen plate 3, and a sealing door 6 hinged to the side of the box body 1 at one side of the discharge chute 5.

[0027] When in use, open the sealing door 6 so that the soaked soybeans on the filter screen 3 can flow out from the discharge trough 5.

[0028] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes an air intake valve 205 connected to the end of the air collection pipe 201 located on the outside of the housing 1 via a threaded groove.

[0029] When in use, open the intake valve 205 to allow compressed air to flow into the air collection pipe 201.

[0030] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a water inlet valve 7 connected to one end of the housing 1 at the top of the air inlet valve 205 via a pipe, and a water outlet valve 8 connected to one end of the housing 1 at the bottom of the discharge trough 5 via a pipe.

[0031] When in use, open the inlet valve 7 to allow clean water to flow into the tank 1, and open the outlet valve 8 to allow the soaking water in the tank 1 to flow out.

[0032] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes a thermostat 9 mounted on one end of the housing 1 via a mounting base. The detection end of the thermostat 9 is located inside the housing 1, and the current output end of the thermostat 9 is electrically connected to the current input end of the heating wire 402 via a power cord.

[0033] During use, the heating of the electric heating wire 402 and its heating temperature can be controlled by the thermostat 9.

[0034] For example, such as Figure 1 As shown, the present invention also includes a maintenance door 10 hinged to one side of the box 1 located at the bottom of the thermostat 9.

[0035] When in use, the access door 10 can be opened to repair the air intake assembly 2 inside the housing 1 and clean the filter screen 3.

[0036] When using this utility model, personnel use an air pipe to connect the air inlet valve 205 to the external air supply equipment, use a water pipe to connect the water supply equipment to the water inlet valve 7, pour soybeans into the box 1, and open the water inlet valve 7 to allow clean water to flow into the box 1.

[0037] After the clean water enters the box 1, the yellow soybeans are soaked inside. During the soaking process, the personnel open the air inlet valve 205 at regular intervals, so that the compressed air flows into the air collection pipe 201 and is divided into the air distribution pipe 202, and then flows into the air outlet one-way valve 203 and then into the clean water through the nozzle 204. The gas enters the clean water and pushes the soybeans to roll, so as to avoid the soybeans being under-soaked or over-soaked in some places.

[0038] The yellow soaking process is controlled by the thermostat 9 to heat the electric heating wire 402. The magnesium oxide powder 403 conducts the temperature of the electric heating wire 402 to the stainless steel plate sleeve 401, which heats the water in the tank 1 to meet the soaking requirements of soybeans.

[0039] After the soybeans have been soaked, open the water outlet valve 8 to drain the soaking water from the tank 1. After the soaking water is drained from the tank 1, the soybeans fall onto the filter screen 3 and are guided by the filter screen 3 to roll towards the discharge chute 5. Open the sealing door 6 to discharge the soaked soybeans.
