Description

Technical Field

[0001] This utility model relates to the field of soybean product processing technology, specifically to a semi-automatic curdling device for soybean products. Background Technology

[0002] Soy product processing can transform a single soybean raw material into various forms of food, such as tofu, dried tofu, tofu skin, soy milk, tofu pudding, and fermented tofu. During processing, steps such as soaking, grinding, and boiling can remove anti-nutritional factors from soybeans, such as trypsin inhibitors and phytic acid, thereby improving the nutritional value of soy products.

[0003] When adding coagulant, the coagulant must be added to the cooked soy milk first. During the process, the coagulant should be added at a steady speed and stirred while adding it to ensure that the coagulant is evenly distributed in the soy milk. The stirring intensity and speed should be controlled to avoid damaging the colloidal structure of the soy milk. After adding the coagulant, let the soy milk stand for a period of time to allow the protein to fully coagulate.

[0004] A search revealed that patent application number 202210738673.1 discloses a semi-automatic brine-adding device for soybean products, comprising: a base frame with a cooking pot on one side; a fixed column on the top of the base frame; a hollow rotating shaft with a bearing seat on one side of the fixed column, and a hollow rotating shaft inside the bearing seat; a brine-adding system connected to the top of the hollow rotating shaft; the brine-adding system including a measuring cylinder on the top of the base frame; an inlet pipe connected to the top of the measuring cylinder; and an inlet / outlet pipe connected to the upper side of the measuring cylinder. The device utilizes a solenoid valve and a pressure reducing valve to control the outflow of quantitative and constant-pressure gas to drive the liquid discharge; an electronic control unit connected to a liquid level sensor receives signals to control the opening and closing of the air pump, the discharge valve, and the inlet valve, achieving precise, quantitative, and uniform brine addition.

[0005] Current coagulation equipment used in soy product processing cannot guarantee the full integration of soy milk and brine during stirring, which can easily lead to uneven protein coagulation after cooling and reduce the quality of soy products. In addition, the current coagulation equipment has a complex structure, occupies a large area, and is not easy to move, which makes it inconvenient to clean the soy milk container. Therefore, we need to propose a semi-automatic coagulation equipment for soy products. Utility Model Content

[0006] The purpose of this invention is to provide a semi-automatic coagulation device for soybean products. A drive mechanism rotates the stirring mechanism at a certain angle, positioning the three-bladed stirring paddle below the surface of the soybean milk at a certain angle. This rotation creates negative pressure below the paddle, forcing the soybean milk at the bottom of the container to rise and circulate repeatedly, achieving thorough fusion of the soybean milk and brine. This ensures uniform protein texture after cooling, improving the quality of the soybean products. The device has a simple structure, and the stirring mechanism can be stored away after use. It occupies little space, is easy to move, and facilitates cleaning of the soybean milk container below the device, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a semi-automatic brine-adding device for soybean products, comprising a base, on which a first support frame and a fixed frame are respectively installed. The first support frame is provided with a brine tank for adding brine to a soybean milk bucket. A solenoid valve is installed on the outlet of the brine tank. A retractable stirring mechanism is provided below the base. A drive mechanism for driving the stirring mechanism to retract is installed on the fixed frame.

[0008] The stirring mechanism includes a rotating shaft, one end of which is connected to a three-bladed stirring paddle, and a temperature sensor is movably mounted on the outer wall of the shaft via a rotating sleeve.

[0009] Preferably, a support plate is mounted on the base, a motor is mounted on the support plate, and a universal coupling is connected between one end of the motor's output shaft and the other end of the rotating shaft.

[0010] Preferably, the driving mechanism includes a cylinder fixed to the top of the fixed frame, one end of the piston rod of the cylinder is connected to a connecting member, and the bottom of the connecting member is connected to the push plate by bolts.

[0011] Preferably, the bottom of the push plate is rotatably mounted with an mounting component, the rotating shaft is inserted and fixed on the mounting component, and a fixing plate is connected between the fixing brackets. The fixing plate has a through hole for the bottom of the push plate to pass through.

[0012] Preferably, a second support frame is also fixed on the base, and an electrical control box with a built-in PLC controller and a 12V power supply is installed on the second support frame. A high-speed camera for real-time monitoring of the protein coagulation state in the soy milk is installed at the bottom of the electrical control box.

[0013] Preferably, one end of the electrical control box is equipped with a temperature control instrument transmitter, a working switch, a charging socket, and a main power switch.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model drives the stirring mechanism to rotate at a certain angle through a driving mechanism, so that the three-blade stirring paddle is below the surface of the soy milk and at a certain angle to the surface of the liquid. The three-blade stirring paddle is driven to rotate and stir, so that negative pressure is generated below the three-blade stirring paddle, thereby forcing the soy milk at the bottom of the soy milk bucket to surge upwards and then circulate repeatedly, so as to achieve full integration of soy milk and brine, ensuring that the coagulated protein after subsequent cooling has a uniform texture, which is beneficial to improving the quality of soy products.

Detailed Implementation

[0021] 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.

[0022] Please see Figs. 1-3This utility model provides a technical solution: a semi-automatic brine-adding device for soybean products, including a base 1, on which a first support frame 2 and a fixed frame 6 are respectively installed. The fixed frame 6 is a U-shaped fixed frame. A brine tank 3 for adding brine to a soybean milk bucket is provided on the first support frame 2. A solenoid valve 4 is installed on the outlet of the brine tank 3 for quantitatively and evenly adding brine to the soybean milk bucket. A retractable stirring mechanism 5 is provided below the base 1. When the stirring mechanism 5 is not in use, it can be stored so that the stirring mechanism 5 is in a horizontal state, reducing the size of the equipment. A drive mechanism 7 for driving the stirring mechanism 5 to retract is installed on the fixed frame 6.

[0023] Simply place the base 1 on the soy milk container. It is suitable for soy milk containers of various sizes and specifications. The device is easy to move and facilitates cleaning of the soy milk containers.

[0024] The stirring mechanism 5 includes a rotating shaft 53, with a three-bladed stirring paddle 55 connected to the outer wall of one end of the shaft 53. When the stirring mechanism 5 is running, the three-bladed stirring paddle 55 is at a certain angle to the surface of the soy milk, i.e., it is inclined to stir. The three-bladed stirring paddle 55 is used to stir and cool the soy milk. The soy milk cools down quickly, shortens the working time, reduces heavy physical labor, and significantly improves work efficiency. During stirring, a negative pressure is generated below the three-bladed stirring paddle 55, which forces the soy milk at the bottom of the soy milk bucket to surge upwards and then circulate repeatedly, thereby achieving full integration of soy milk and brine. A temperature sensor 54 is movably installed on the outer wall of the shaft 53 through a rotating sleeve. The temperature sensor 54 is used to detect the temperature of the soy milk in real time.

[0025] A support plate 12 is installed on the base 1. One side of the support plate 12 is inclined. A motor 51 is installed on the support plate 12. A universal coupling 52 is connected between one end of the output shaft of the motor 51 and the other end of the rotating shaft 53. When the rotating shaft 53 is flipped, the motor 51 can still drive the rotating shaft 53 to rotate.

[0026] The drive mechanism 7 includes a cylinder 71 fixed to the top of the fixed frame 6. One end of the piston rod of the cylinder 71 is connected to a connector 72, and the bottom of the connector 72 is connected to the push plate 73 by bolts.

[0027] The bottom of the push plate 73 is rotatably mounted with a mounting part 74, and the rotating shaft 53 is inserted and fixed on the mounting part 74. A fixing plate 10 is also connected between the fixing brackets 6, and a through hole is opened on the fixing plate 10 for the bottom of the push plate 73 to pass through.

[0028] When cylinder 71 operates, it drives push plate 73 to move down through connector 72. Push plate 73 pushes mounting part 74 down. Since push plate 73 and mounting part 74 are rotatably connected, the shaft 53 in stirring mechanism 5 is rotated through mounting part 74, causing the three-blade stirring paddle 55 and temperature sensor 54 to move below the surface of the soy milk.

[0029] A second support frame 11 is also fixed on the base 1. An electrical control box 8 with a built-in PLC controller and a 12V power supply is installed on the second support frame 11. A high-speed camera 9 for real-time monitoring of the protein coagulation state in the soy milk is installed at the bottom of the electrical control box 8. The high-speed camera 9 is tilted and aimed at the soy milk bucket, and the high-speed camera 9 has a built-in transmitter signal output.

[0030] One end of the electrical control box 8 is equipped with a temperature control instrument transmitter 81, a working switch 82, a charging socket 83, and a main power switch 84.

[0031] Solenoid valve 4, cylinder 71, motor 51, temperature sensor 54, and high-speed camera 9 are all connected to electrical control box 8. The specific connection method is existing technology and common knowledge to those skilled in the art, so it will not be described in detail here.

[0032] In use, the device is placed on the cooked soy milk container. The main power switch 84 and the work switch 82 are turned on. The cylinder 71 operates, driving the push plate 73 downwards via the connecting piece 72. The push plate 73 pushes the mounting piece 74 downwards. Due to the rotatable connection between the push plate 73 and the mounting piece 74, the rotating shaft 53 in the stirring mechanism 5 is rotated via the mounting piece 74, causing the three-blade stirring paddle 55 and the temperature sensor 54 to move below the surface of the soy milk. Then, the PLC controller stops the cylinder 71. Simultaneously, the PLC controller drives the motor 51, which in turn drives the three-blade stirring paddle 55 to rotate via the universal coupling 52 and the rotating shaft 53, initiating the stirring, mixing, and cooling of the soy milk. The temperature sensor 54 displays the soy milk temperature in real time via the temperature control transmitter 81. When the soy milk temperature is detected... When the specified temperature (e.g., 80℃) is reached, the PLC controller opens the solenoid valve 4 and the high-speed camera 9 on the brine tank 3. The solenoid valve 4 opens, and brine is slowly and evenly added to the soy milk. The high-speed camera 9 monitors the coagulation state of the protein in the soy milk in real time and compares it with the coagulation state stored in its internal memory. When the specified coagulation state is reached, the transmitter built into the high-speed camera 9 closes the solenoid valve 4 through the PLC controller to block the addition of brine and stop the motor 51 from driving the three-blade stirring paddle 55. At the same time, the PLC controller opens the cylinder 71, and the piston rod of the cylinder 71 resets. Through the connector 72, push plate 73, and mounting part 74, the three-blade stirring paddle 55 leaves the surface of the soy milk and returns to its initial position. After 3 seconds, the PLC controller automatically turns off the main power switch 84 and the working switch 82.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
