Description

Technical Field

[0001] This utility model relates to the field of soybean product processing technology, and in particular to an integrated device for preventing overflow, defoaming and heat recovery during the soybean product boiling process. Background Technology

[0002] In the production of soy products (such as tofu, soy milk, and tofu pudding), boiling the soy milk is a crucial step. Currently, the industry generally uses jacketed kettles or open-type boiling kettles for heating and boiling. During this process, because soy milk is rich in protein, it produces a large amount of fine and stable foam when heated to the boiling point. These foams expand rapidly, which can easily cause "false boiling" and overflow the pot (commonly known as "overflow"). This not only leads to waste of raw materials and reduced product yield, but also dirtys the equipment and working environment, increasing cleaning costs.

[0003] In addition, traditional methods for solving the problem of overflowing mainly rely on manual intervention, such as spraying defoamers (which may affect product quality and food safety) or pouring cold water (which causes a sudden drop in temperature, increased energy consumption, and uneven heating). These methods have low automation and cannot achieve precise control.

[0004] Therefore, to prevent overflow, operators usually reduce the heat or stop heating, which prolongs the boiling time, reduces production efficiency, and more importantly, the overflowing foam and steam carry a large amount of high-temperature heat energy. This energy is currently being directly discharged into the workshop environment, which not only causes a huge waste of energy, but also leads to high temperature and humidity in the workshop environment, deteriorating working conditions.

[0005] To address the aforementioned issues, this invention provides an integrated device for preventing overflow, defoaming, and recovering heat energy during the cooking process of soybean products. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an integrated device for preventing overflow, defoaming, and recovering heat energy during the cooking process of soybean products, thus solving the problems mentioned in the background technology.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated device for preventing overflow, defoaming and recovering heat energy during the cooking process of soybean products, including a cooking tank, and also including an anti-overflow and defoaming system and a heat energy recovery system; The upper end of the boiling tank is equipped with a cooling jacket, and the top of the boiling tank is equipped with a flow guide shroud. The bottom of the inner part of the boiling tank is equipped with a heating element. The anti-overflow and defoaming system includes a cold soy milk spray pipe installed on the upper end of the inner wall of the cooking tank, and nozzles evenly distributed at the bottom of the cold soy milk spray pipe. A heat exchange circulation pipe is arranged around the inside of the cooling jacket. It also includes a conveying pipe installed on the upper end of the outer wall of the cooking tank, and a conveying pump is connected to the lower end of the conveying pipe. The heat recovery system includes a steam pipe connected to the top of the guide shroud, one end of which is connected to a heat exchanger, and the lower end of the heat exchanger is connected to the input end of the delivery pump through a cold soy milk outlet pipe.

[0008] As a further technical solution of this utility model, the output end of the delivery pump is connected to the delivery pipe, the delivery pipe extends through the cooling jacket into its interior and is connected to one end of the heat exchange circulation pipe, and the other end of the heat exchange circulation pipe extends through the cooking tank and is connected to the cold soy milk spray pipe.

[0009] As a further technical solution of this utility model, the cold soy milk spray pipe is a ring-shaped pipe, and the nozzles are distributed in a ring shape; A foam level sensor is also installed inside the cooling jacket at the upper end of the boiling tank.

[0010] As a further technical solution of this utility model, the other end of the steam pipe is connected to the hot side inlet of the heat exchanger, and the cold side inlet of the heat exchanger is connected to the cold soy milk inlet pipe. The hot side outlet of the heat exchanger is connected to the gas-liquid pipe, and the cold side outlet of the heat exchanger is connected to the cold soy milk outlet pipe. The cold soy milk inlet pipe is connected to the cold soy milk outlet pipe, the steam outlet pipe is connected to the gas-liquid outlet pipe, and the heat exchanger is a plate heat exchanger or a shell-and-tube heat exchanger.

[0011] As a further technical solution of this utility model, the heating element is an electromagnetic heating plate, and the electromagnetic heating plate is distributed in a coil shape at the bottom of the boiling tank. The air deflector is horn-shaped or cone-shaped.

[0013] A feed pipe is installed on the outer side of the upper end of the cooking tank, and a discharge pipe is installed on the outer side of the lower end of the cooking tank. Both the feed pipe and the discharge pipe are equipped with control valves.

[0014] This utility model provides an integrated device for preventing overflow, defoaming, and recovering heat energy during the cooking process of soybean products, which has the following advantages compared with the prior art: 1. This design is an integrated device for preventing overflow and defoaming and recovering heat energy during the cooking process of soybean products. By setting up an anti-overflow and defoaming system, when the foam level sensor detects that foam is about to overflow, the PLC controller controls the delivery pump to work, and delivers the preheated cold soybean milk to the cold soybean milk spray pipe through the delivery pipe and heat exchange circulation pipe. Then, it is sprayed onto the foam surface through the nozzle. The low temperature liquid destroys the stability of the foam film, realizing automatic and precise defoaming, avoiding the drawbacks of manual intervention, and reducing raw material waste and cleaning costs.

Through the setting of the heat energy recovery system, the steam and foam carrying a large amount of heat energy generated during the cooking process can be guided to the heat exchanger through the guide hood and steam exhaust pipe. The steam exchangers exchange heat with the cold soybean milk entering through the cold soybean milk inlet pipe, preheating the cold soybean milk and realizing the recovery and utilization of heat energy, reducing energy consumption, and improving the workshop environment. Moreover, the combination of the cooling jacket and the heat exchange circulation pipe can not only preheat the cold soybean milk, but also cool the top of the cooking tank, further reducing the generation of foam.

[0019] Please see Figure 1-4This utility model provides a technical solution for an integrated device for preventing overflow, defoaming, and recovering heat energy during the cooking process of soy products: An integrated device for preventing overflow, defoaming, and recovering heat energy during the cooking process of soy products includes a cooking tank 1, an anti-overflow and defoaming system, and a heat energy recovery system. A PLC controller is also provided on the outer surface of the cooking tank 1, and a temperature sensor is also embedded in the inner wall of the cooking tank 1. A feed pipe 11 is installed on the outer side of the upper end of the cooking tank 1, and a discharge pipe 12 is installed on the outer side of the lower end of the cooking tank 1. Control valves are provided on both the feed pipe 11 and the discharge pipe 12 to facilitate the addition or discharge of soy milk into the cooking tank 1. A cooling jacket 2 is installed at the upper end of the cooking tank 1, and a flow guide 3 is provided at the top of the cooking tank 1. The flow guide 3 is funnel-shaped or cone-shaped. Its function is to guide the overflowing steam and fine foam to the upper outlet when the foam rises, and discharge it to the heat exchanger 4 through the steam exhaust pipe 31. A heating element is provided at the inner bottom of the cooking tank 1. The heating element is an electromagnetic heating plate, and the electromagnetic heating plate is distributed in a coil shape at the inner bottom of the cooking tank 1 to heat the soy milk inside the cooking tank 1. The anti-overflow and defoaming system includes a cold soy milk spray pipe 52 installed on the upper part of the inner wall of the cooking tank 1, and nozzles 53 evenly distributed at the bottom of the cold soy milk spray pipe 52. A heat exchange circulation pipe 21 is arranged around the inside of the cooling jacket 2. It also includes a conveying pipe 51 installed on the upper part of the outer wall of the cooking tank 1. The lower end of the conveying pipe 51 is connected to a conveying pump 5. The output end of the conveying pump 5 is connected to the conveying pipe 51. The conveying pipe 51 extends through the cooling jacket 2 into its interior and is connected to one end of the heat exchange circulation pipe 21. The other end of the heat exchange circulation pipe 21 extends through the cooking tank 1 and is connected to the cold soy milk spray pipe 52. The cold soy milk spray pipe 52 is a ring pipe, and the nozzles 53 are arranged in a ring. The nozzles 53 face the liquid surface inside the tank, which makes it convenient to evenly spray the preheated low-temperature soy milk or condensed water onto the rising foam layer. The spraying of low-temperature droplets can instantly destroy the surface tension of the foam, achieving rapid defoaming. At the same time, local cooling can inhibit the further expansion of the foam, thereby eliminating it before it overflows. A foam level sensor 6 is also installed inside the cooling jacket 2 at the upper end of the boiling tank 1 to detect the foam level.

[0020] The heat recovery system includes a steam pipe 31 connected to the top of the flow guide shroud 3. One end of the steam pipe 31 is connected to a heat exchanger 4. The lower end of the heat exchanger 4 is connected to the input end of the delivery pump 5 through a cold soybean milk outlet pipe 43. The other end of the steam pipe 31 is connected to the hot side inlet of the heat exchanger 4. The cold side inlet of the heat exchanger 4 is connected to a cold soybean milk inlet pipe 42. The hot side outlet of the heat exchanger 4 is connected to a gas-liquid pipe 41. The cold side outlet of the heat exchanger 4 is connected to the cold soybean milk outlet pipe 43. The cold soybean milk inlet pipe 42 is connected to the cold soybean milk outlet pipe 43. The steam pipe 31 is connected to the gas-liquid pipe 41. The heat exchanger 4 is a plate heat exchanger or a shell-and-tube heat exchanger.

[0021] The working principle of this utility model is as follows: When in use, soy milk is added into the cooking tank 1 through the feed pipe 11, the control valve on the feed pipe 11 is closed, and the heating element is started to heat the soy milk. During the heating process, the temperature sensor monitors the temperature of the soy milk in real time and transmits the information to the PLC controller. When the soy milk boils and produces foam, and the foam level reaches the detection range of the foam level sensor 6, the foam level sensor 6 transmits a signal to the PLC controller. The PLC controller controls the delivery pump 5 to start, and the cold soy milk enters the cold side of the heat exchanger 4 through the cold soy milk inlet pipe 42. At the same time, the steam and foam generated in the cooking tank 1 enter the hot side of the heat exchanger 4 through the steam exhaust pipe 31 under the guidance of the guide shroud 3. The cold soy milk exchanges heat with the steam and high-temperature foam in the heat exchanger 4, and the cold soy milk is preheated. After the steam and foam condense, they are discharged through the gas-liquid exhaust pipe 41. The preheated cold soy milk enters the delivery pump 5 through the cold soy milk outlet pipe 43, and is then transported to the heat exchange circulation pipe 21 in the cooling jacket 2 through the delivery pipe 51. After further absorbing heat in the cooling jacket 2, it enters the cold soy milk spray pipe 52, and is finally sprayed onto the foam surface through the nozzle 53 to disrupt the stability of the foam film and achieve defoaming. After the soy milk is cooked, the control valve on the discharge pipe 12 is opened to discharge the soy milk.
