Description

Technical Field

[0001] The invention relates to the field of tofu making, in particular to a coagulant production device and a coagulant production method. Background Art

[0002] Tofu was invented by Liu An, King of Huainan and grandson of Emperor Gaozu of Han Dynasty in China. It has a history of thousands of years. Tofu is the main ingredient of vegetarian dishes in my country. After continuous transformation and diversified development among the people, it has gradually become popular and is known as "plant meat".

[0003] At present, the tofu coagulants on the market include: gypsum (calcium sulfate CaSO4.2H2O), brine (magnesium chloride MgCl2), lactone (gluconolactone), etc. Among them, tofu made with gypsum or gluconolactone as coagulants is easy to sour, and tofu made with gypsum as a coagulant was found to have gypsum residues during neutralization and coagulation, which brings concerns to the people. Tofu made with bittern as a coagulant was found to have magnesium ion residues, and the tofu often tastes slightly bitter. If the magnesium chloride remaining in the yellow slurry is not fully neutralized, it will cause magnesium chloride in the tofu, which poses a greater food safety risk.

[0004] In addition, the cost of the above-mentioned traditional coagulants for making tofu is relatively high. For example, if 5 tons of beans are used to make tofu every day in a year, 400 kilograms of gypsum are needed. The price of each kilogram of gypsum is about 300 yuan, so the cost of gypsum is 100,000 yuan per year. The cost of using brine is similar to that of using gypsum. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a coagulant production device and a coagulant production method.

Since the water coming out of the nozzle 24 is pressurized, the water will produce elastic mist-like water splashes after hitting the scattering baffle 25, forming small droplets, thereby increasing the contact area between water and gas. Moreover, in the process of the water splashes falling into the water in the kettle body 12, the water splashes will first contact with the gas, and the soluble gas will dissolve in the water splashes, making the soluble gas more easily dissolved in the water in the kettle body 12.

The second water level sensor 28 is arranged in the kettle body 12, and the second water level sensor 28 is arranged at a preset minimum water level. The second water level sensor 28 is used to judge whether the water level in the kettle body 12 is lower than the preset minimum water level. The controller 60 is electrically connected to the water pump 21, the first water level sensor 27, and the second water level sensor 28 respectively. When the water level in the kettle body 12 is higher than the preset maximum water level, the controller 60 controls the water pump 21 to stop working, and the water pump 21 stops pumping water to the kettle body 12; when the water level in the kettle body 12 is lower than the preset minimum water level, the controller 60 controls the collection component 50 to stop working, and the collection component 50 stops collecting the electrolytic water solution in the kettle body 12.

[0036] See also Figure 1 and Figure 2 The soluble gas provided by the gas supply component 30 can be stored in a gas tank in the form of a pure substance, or it can be directly used as air in the external environment. In this embodiment, the gas supply component 30 directly uses air to provide soluble gas to the kettle body 12. Specifically, the gas supply component 30 includes an air compressor 31, a gas storage tank 32, and an air pipe 33. Among them, the air compressor 31 is connected to the air inlet of the gas storage tank 32. The air outlet of the gas storage tank 32 is connected to the inner cavity of the kettle body 12 through the air pipe 33. The air pipe 33 passes through the kettle cover 13 and extends to the bottom of the inner cavity of the kettle body 12. After the gas comes out of the air pipe 33, the gas will move from the bottom of the kettle body 12 to the top of the kettle body 12. In addition, the air pipe 33 is made of insulating material, and the air pipe 33 is insulated and sealed with the kettle cover 13 to improve the safety performance of the equipment and avoid leakage.

The controller 60 is electrically connected to the air compressor 31 and the first pressure sensor 34 respectively. When the first pressure sensor 34 detects that the air pressure in the kettle body 12 is lower than the minimum pressure value preset by the controller 60, the controller 60 controls the air compressor 31 to work, and the air compressor 31 sends air to the air storage tank 32. The air in the air storage tank 32 then enters the kettle body 12 through the air pipe 33, thereby increasing the pressure in the kettle body 12.

[0038] See also Figure 1 and Figure 2 In order to control the pressure in the kettle body 12 to maintain within a certain pressure range, an exhaust valve 35 is provided on the kettle cover 13.

The controller 60 is electrically connected to the exhaust valve 35. In the actual working process, the controller 60 starts the air compressor 31 and opens the exhaust valve 35 at the same time. In the process of the air compressor 31 sending air to the kettle body 12, the gas in the kettle body 12 will flow out through the exhaust valve 35. Through this method of simultaneous inflation and exhaust, soluble gas can be timely sent to the kettle body 12, and the water-insoluble gas in the kettle body 12 can be timely discharged, improving work efficiency and production quality. In addition, the first pressure sensor 34 is used to continuously monitor the pressure in the kettle body 12. When the first pressure sensor 34 detects that the air pressure in the kettle body 12 is lower than the minimum pressure value preset by the controller 60, the working intensity of the air compressor 31 is increased and the exhaust volume of the exhaust valve 35 is reduced; when the first pressure sensor 34 detects that the air pressure in the kettle body 12 is higher than the maximum pressure value preset by the controller 60, the working intensity of the air compressor 31 is reduced and the exhaust volume of the exhaust valve 35 is increased, so that the air pressure in the kettle body 12 is maintained within the required pressure range.

[0039] See also Figure 1 and Figure 2In order to further improve the control accuracy and work efficiency, a second pressure sensor 36 is installed on the exhaust valve 35.

When the first pressure sensor 34 detects that the pressure in the kettle body 12 exceeds the preset safety pressure value, the controller 60 opens the safety pressure relief valve 37, and the safety pressure relief valve 37 starts to release pressure to ensure safety.

[0041] In this embodiment, the pressure in the kettle body 12 needs to be maintained at 0.6-0.8 MPa, and the safety pressure in the kettle body 12 cannot exceed 10 MPa.
