Description

Technical Field

[0001] This utility model relates to the field of soybean product preparation technology, and in particular to an automatic pressureless soy pulping system. Background Technology

[0002] Boiling the soybeans is a crucial step in making soy milk or tofu. It mainly involves grinding soaked soybeans and then heating them to a boil. During this heating process, once a certain temperature is reached, a large amount of foam often appears in the boiling tank. Boiling causes an increase in internal pressure, and sometimes the foam even overflows. Therefore, it is often necessary to inject a defoamer into the boiling tank. However, existing defoamer injection methods use quantitative injection, and excessive injection can affect the taste of the soy milk. Therefore, developing a boiling system that allows for the precise injection of defoamer has become a pressing need for those skilled in the art. Utility Model Content

[0003] The purpose of this invention is to propose an automatic pressureless slurry firing system that can add defoamer in appropriate amounts based on the liquid level and temperature inside the slurry firing tank.

[0004] To achieve the above objectives, this utility model proposes an automatic pressureless slurry firing system, including a slurry firing tank, a defoaming device, a temperature control probe, a liquid level sensor, and a control unit;

[0005] The temperature control probe and liquid level sensor are placed inside the slurry tank, and both the liquid level sensor and the temperature control probe are connected to the control unit via signal.

[0006] The defoaming device includes a defoamer tank, a defoamer pipe, and a jet pump. The outlet of the defoamer tank is connected to the inlet of the jet pump through a pipe, and the outlet of the jet pump is connected to the top of the slurry tank through the defoamer pipe.

[0007] Furthermore, the defoamer tank is connected to a steam pipe, and a check valve is installed on the defoamer pipe.

[0008] Furthermore, a return water pipe is provided near the bottom of the defoamer pipe, with the outlet of the return water pipe facing the inlet of the defoamer tank, and a valve is installed on the return water pipe.

[0009] Furthermore, a water pipe is connected to the top of the slurry-burning tank.

[0010] Furthermore, the bottom of the slurry tank is the discharge port, and a glass sight glass is provided on the side of the slurry tank. The side of the slurry tank is also connected to the slurry inlet pipe.

[0011] Furthermore, steam pipes are arranged at the bottom of the slurry-firing tank.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The automatic pressureless soy milk cooking system of this utility model injects an appropriate amount of defoamer according to the liquid level and temperature inside the soy milk cooking tank, so as to avoid the introduction of excessive defoamer affecting the taste of soy milk and also avoid affecting the cooking efficiency of soy milk.

[0014] 2. The automatic pressureless slurry burning system of this utility model can realize automatic cleaning of the inner wall of the barrel, reducing the difficulty of cleaning. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the overall structure of the automatic pressureless slurry burning system in the embodiment of this utility model. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0017] like Figure 1 As shown, this utility model proposes an automatic pressureless slurry firing system, which consists of a slurry firing tank 1, a defoaming device, a temperature control probe 2, a liquid level sensor and a control unit;

[0018] The specific structure is as follows: the temperature control probe 2 and the liquid level sensor are placed inside the slurry tank 1. Both the liquid level sensor and the temperature control probe 2 are connected to the control unit. The temperature control probe 2 senses the temperature inside the tank, and the liquid level sensor senses the position of the liquid inside the tank to detect whether the cooking foam inside the tank has reached the liquid level line.

[0019] In this embodiment, the defoaming device includes a defoamer tank 3, a defoamer pipe 4, and a jet pump 5. The outlet 10 of the defoamer tank 3 is connected to the inlet of the jet pump 5 via a pipe. The outlet 10 of the jet pump 5 is connected to the top of the soy milk boiling tank 1 via the defoamer pipe 4. The jet pump 5 is signal-connected to the control unit. When the liquid level sensor detects that the liquid level in the tank has risen to the liquid level line, it indicates that there is too much foam inside. At this time, the jet pump 5 is controlled to inject a certain amount of liquid into the soy milk boiling tank 1 to reduce the amount of foam inside. In addition, the system can also be preset. For example, when the temperature reaches 70°C, foam will generally be generated inside. At this time, the system controls the jet pump 5 to inject a certain amount of defoamer into the soy milk boiling tank 1. The amount of defoamer injected is related to the amount of soy milk in the soy milk boiling tank 1 to avoid adding too much defoamer and affecting the taste of the soy milk.

[0020] In this embodiment, the defoamer tank 3 is connected to a steam pipe 6 for heating the defoamer. A check valve 7 is installed on the defoamer pipe 4 to prevent the soybean milk inside the boiling tank 1 from flowing back into the defoamer tank 3. A return water pipe 8 is located near the bottom of the defoamer pipe 4, with its outlet facing the inlet of the defoamer tank 3. A valve is installed on the return water pipe 8 so that after the boiling process is completed, the defoamer in the upper part of the defoamer pipe 4 can return to the defoamer tank 3 via the return water pipe 8 for recycling.

[0021] In this embodiment, a water pipe 9 is connected to the top of the slurry-cooking tank 1. After slurry cooking is completed, the inner wall of the slurry-cooking tank 1 can be cleaned through the water pipe 9. Regular cleaning can ensure that the inside is clean. The bottom of the slurry-cooking tank 1 is a discharge port 10, from which the cleaning water and the cooked soybean milk are discharged. A glass viewing mirror 12 is provided on the side of the slurry-cooking tank 1 for easy observation of the internal cooking process. A slurry inlet pipe is also connected to the side of the slurry-cooking tank 1 for feeding materials. 11 steam pipes are arranged at the bottom of the slurry-cooking tank 1 for heating the internal materials.

[0022] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
