Description

Technical Field

[0001] This utility model relates to the field of soybean product processing technology, specifically to an automatic coagulation device for controlling temperature. Background Technology

[0002] The coagulation process is the chemical reaction between soy milk and a coagulant during soy product processing. A specific amount of soy milk is coagulated using the optimal amount of coagulant. Then, process parameters such as soy milk concentration, brine concentration, soy-brine ratio, stirring method, and coagulation temperature are carefully controlled. When soy milk is heated, the protein molecules in it increase their internal energy and move faster. The higher the temperature, the faster the protein molecules move, and the greater the chance of them combining with the calcium and magnesium ions in the coagulant, resulting in a faster reaction rate between the coagulant and soy milk. However, a faster reaction rate is not always better; a suitable reaction rate is needed for optimal results. A suitable coagulation temperature is also crucial for a high-quality final product. Therefore, a temperature-controlled coagulation device is required.

[0003] Existing traditional soy product coagulation devices have certain deficiencies in terms of mixing uniformity. Most existing equipment relies on a single stirring structure, which cannot achieve the vertical circulation of the slurry. This leads to the slurry at the bottom easily settling and uneven heating, affecting the uniform distribution of the coagulant and thus reducing the quality of soy products (such as layering and rough texture). Utility Model Content

[0004] The purpose of this invention is to provide an automatic dispensing device for controlling temperature, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic dispensing device for controlling temperature, comprising a dispensing tank and a cover plate, the top opening of the dispensing tank being provided with a cover plate, the cover plate being provided with an extraction and circulation component, and the cover plate also being provided with a stirring mechanism matching the extraction and circulation component, a liquid storage tank being provided on one side of the cover plate, and a heating component being provided on the inner wall of the dispensing tank.

[0006] Preferably, in order to facilitate mixing between the upper and lower layers and ensure uniform mixing and heating, the extraction and circulation assembly includes a connecting pipe located at the bottom of the slurry tank. Extraction holes are equidistantly opened on the periphery of the connecting pipe. Both ends of the connecting pipe are connected to vertical pipes. The vertical pipes pass through the cover plate and extend upwards, and are provided with extraction pipes. The extraction pipes are connected to the input end of the circulation pump, and the output end of the circulation pump is provided with a discharge pipe.

[0007] Preferably, to ensure stability and firmness, a mounting base is fixedly provided at the bottom of the circulating pump, and the mounting base is fixedly connected to the cover plate.

[0008] Preferably, in order to facilitate mixing, the mixing mechanism includes a hollow tube disposed in the middle of the cover plate, the hollow tube passing through the cover plate and extending downwards to have stirring rods disposed at equal intervals, a driven gear fixedly disposed on the top periphery of the hollow tube, a main gear meshing with one side of the driven gear, the main gear being fixedly connected to the output end of the motor, and the motor being fixedly disposed on the cover plate.

[0009] Preferably, in order to facilitate mixing the lower layer of soy product slurry extracted by the extraction and circulation component from top to bottom during rotation and stirring, the bottom end of the discharge pipe is connected to the hollow pipe through a rotary joint, and the stirring rod is provided with liquid outlets at equal intervals that are connected to the hollow pipe.

[0010] Preferably, in order to heat the interior as needed, the heating assembly includes a heating chamber formed in the inner wall of the slurry tank, and a heating device is arranged around the inside of the heating chamber.

[0011] Preferably, in order to reduce heat exchange with the outside, an insulation layer is provided on the inner wall of the heating chamber near the outside of the slurry tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the extraction and circulation component, combined with the stirring mechanism, facilitates the stirring and mixing of soy product slurry. It also allows for easy extraction of the soy product slurry from the bottom to the top, which then flows back into the coagulation tank, achieving mixing of the upper and lower layers. This avoids sedimentation and ensures uniform mixing and heating, without affecting subsequent processing. The heating component allows for heating of the coagulation tank as needed, without affecting processing. Furthermore, the insulation layer reduces heat exchange with the outside environment, thus reducing energy consumption. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides an embodiment of an automatic coagulation device for temperature control, comprising a coagulation tank 1 for holding soy product slurry, and a cover plate 2 at the top opening of the coagulation tank 1 (connected by a sealing device, such as a sealing groove and a sealing ring). The cover plate 2 and the coagulation tank 1 are connected and fixed by a buckle, etc., and are detachable, making it easy to remove the cover plate 2 as a whole for easy cleaning. A storage tank 8 is provided on one side of the top of the cover plate 2 (for temporary storage of coagulant; the top of the storage tank 8 is provided with a filling pipe for easy connection of coagulant; the coagulant in the storage tank 8 can be automatically added quantitatively by a metering pump, etc., a relatively mature technology, which will not be described in detail here). The side wall of the coagulation tank 1 may also be provided with a discharge pipe, which can discharge the soy product slurry mixed with coagulant as needed. The discharge facilitates subsequent static solidification and other operations. The assembly is selected according to the actual situation. It is a relatively mature technology and will not be elaborated here. In order to facilitate the control of the internal temperature according to the processing needs and not affect the processing use, a heating chamber 17 with a heating component is opened on the inner wall of the slurry tank 1. The heating chamber 17 is surrounded by a heating device 19 (which can be electrically heated, such as a resistance wire, or can be implemented by circulating heat transfer oil or water. It is a relatively mature technology and will not be elaborated here). The corresponding slurry tank 1 can be equipped with a temperature sensor (not shown in the figure), which can be electrically connected to a PLC or microcontroller to facilitate temperature control with the heating device 19 and ensure accuracy. In order to reduce heat exchange with the outside, an insulation layer 18 (which can be insulation cotton or other insulation materials) is provided on the inner wall of the heating chamber 17 near the outside of the slurry tank 1.

[0021] Please see Figures 1-5To ensure uniform heating and mixing, prevent slurry sedimentation or clumping, and ensure consistent slurry application, a connecting pipe 10 for a circulation mechanism is horizontally installed at the bottom of the slurry tank 1. The connecting pipe 10 has equidistant extraction holes 3 on its sides to facilitate the extraction of slurry from the bottom, allowing it to flow back into the slurry tank 1 for easier mixing. Vertical pipes 9 are connected to both ends of the connecting pipe 10, extending from the cover plate 2 and connecting to an extraction pipe 6. The extraction pipe 6 connects to the input end of the circulation pump 5, and the output end of the circulation pump 5 has a discharge pipe 7. A mounting base 16 is fixed to the bottom of the circulation pump 5 (by welding), and the mounting base 16 is fixed to the cover plate 2 (by screws) to ensure the stability and secure connection of the circulation pump 5. For convenient mixing, a stirring mechanism is also provided on the cover plate 2. The stirring mechanism includes components... A hollow tube 11 is located in the middle of the cover plate 2. The hollow tube 11 passes through the cover plate 2 and extends downwards, where stirring rods 12 are evenly spaced. A driven gear 14 is fixedly installed on the top periphery of the hollow tube 11. A main gear 13 meshes with one side of the driven gear 14. The main gear 13 is fixedly connected to the output end of the motor 4 through a coupling. The motor 4 is fixed (through a mounting bracket, not shown in the figure) on the cover plate 2 to ensure the stability and firmness of the motor 4. The bottom end of the discharge pipe 7 is connected to the hollow tube 11 through a rotary joint 15. Liquid outlets 20 are evenly spaced below the stirring rods 12 and communicate with the hollow tube 11. This allows the bottom bean product slurry to be easily extracted from the extraction hole 3 of the connecting pipe 10 and then flow out through the liquid outlets 20 of the stirring rods 12 below the hollow tube 11. This ensures that the mixing is sufficient and uniform, and that the heating is sufficient and uniform, without affecting subsequent processing and use.

[0022] Working Principle: When using this invention, the heating device 19 operates to heat the bean curd slurry during mixing. Simultaneously, the circulation pump 5 operates to draw the bean curd slurry from the bottom into the vertical pipe 9 through the extraction hole 3 on the connecting pipe 10, then into the circulation pump 5 through the extraction pipe 6, and finally pumped out through the output end of the circulation pump 5. The slurry flows into the hollow pipe 11 through the discharge pipe 7 and the rotary joint 15, and then flows out through the liquid outlet 20 under the stirring rod 12. This achieves flow mixing between the upper and lower layers, preventing sedimentation and ensuring uniform heating. The motor 4 operates to rotate the main gear 13, which in turn rotates the driven gear 14 and the hollow pipe 11, further mixing the liquid with the stirring rod 12. The rotary joint 15 does not affect the liquid transport during rotation, facilitating mixing operations. When coagulant needs to be added, it is added through the storage tank 8. The above operations are then repeated to ensure thorough and uniform mixing. After mixing, subsequent static coagulation operations can be performed.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
