Technical Field
[0001] This utility model relates to the technical field of dried bean curd production equipment, specifically to an automated integrated equipment for the entire dried bean curd production process. Background Technology
[0002] As a traditional soy product, dried bean curd sticks are loved by consumers. In the traditional production process of dried bean curd sticks, it mainly relies on manual operation. From selecting beans, soaking beans, grinding soy, boiling soy, to peeling the sticks and drying, each step requires a high level of experience and skill from the workers.
[0003] However, this traditional production method has many problems. The lack of an effective stirring device in the soy milk boiling stage leads to sedimentation or uneven dispersion of the soy milk. This directly results in inconsistent soy milk quality when sprayed onto the forming belt, causing uneven thickness of the formed bean curd sheets. Consequently, the produced bean curd sticks vary significantly in appearance, texture, and nutritional distribution, severely impacting product quality. Furthermore, cleaning the forming belt is usually done manually, which is not only labor-intensive and time-consuming, but also difficult to thoroughly clean manually due to the complex structure of the belt. Long-term accumulation of soy milk adhering to the forming belt interferes with the spraying of soy milk and the formation of the bean curd sheets, affecting the normal operation of the equipment and increasing the frequency of downtime for maintenance. At the same time, the traditional bean curd stick production process has poor coordination between processes, a high degree of manual intervention, long waiting times, and low production efficiency, making it difficult to meet the needs of large-scale production.
[0004] To address the aforementioned issues, this application proposes an integrated automated equipment for the entire process of dried bean curd production. Utility Model Content
[0005] The purpose of this utility model is to provide an automated integrated equipment for the entire process of dried bean curd production, so as to solve the problems mentioned in the background art, such as uneven soy milk spraying, inconvenient cleaning of the forming belt, and poor connection between various processes, resulting in a high degree of manual intervention.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated integrated equipment for the entire process of dried bean curd production, comprising a frame, with forming belts slidably connected to the inner surfaces of both sides of the frame, and a spray pipe, a cutting wheel, a grooved roller, a pressing roller, a cutting knife, and a drying box sequentially installed from left to right on the upper end of the frame. The spray pipe is connected to a boiling pot through a pipe, and a pressure pump is installed on the pipe. The inlet of the boiling pot is connected to a grinding machine through a pipe. A heating base is fixedly installed on the lower outer surface of the boiling pot. A rotating shaft is provided on the inner side of the boiling pot. The upper end of the rotating shaft is connected to a motor located at the upper end of the boiling pot, and a spiral impeller and a scraper are fixedly connected to the outer wall of the rotating shaft.
[0007] Preferably, the scraper consists of two pieces, which are vertically installed on the inner side of the cooking pot. One side of the scraper is fixedly connected to the rotating shaft via a crossbar, and the other side is in close contact with the inner wall of the cooking pot.
[0008] Preferably, the spray pipe is located at the upper end of the forming belt, and a plurality of fan-shaped nozzles are installed at its bottom, and a heating plate is provided below the forming belt.
[0009] Preferably, the two ends of the slitting roller, the grooved roller and the pressing roller are rotatably connected to the brackets, and the bottom of the brackets is fixedly installed on the upper end of the frame.
[0010] Preferably, a water tank is fixedly installed at the bottom of the frame, and a nozzle is provided at the bottom of the forming belt. The nozzle is connected to the water tank through a water pipe, and a water pump is installed on the water pipe.
[0011] Preferably, a filter screen is horizontally installed in the middle of the inner side of the water tank, and the connection between the water pipe and the water tank is close to the water tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention uses a motor to drive a rotating shaft and a spiral impeller to stir the soy milk in the cooking pot, preventing sedimentation and uneven dispersion. This ensures that the soy milk entering the spray pipe has a consistent concentration and texture, which facilitates spreading on the forming belt. The resulting soy skin has a uniform thickness, and the appearance, taste, and nutritional distribution of the produced tofu skin are more consistent, effectively improving product quality.
[0014] This invention utilizes a water tank, water pipes, water pump, and nozzles at the bottom of the frame to form an automatic cleaning system. The water pump pressurizes the water and sprays it from the nozzles to the bottom of the forming belt, avoiding the tedious manual cleaning, significantly reducing labor costs, fully covering the surface of the forming belt, preventing slurry from adhering and affecting subsequent processes, ensuring stable equipment operation, reducing downtime for maintenance, and improving production efficiency.
[0015] This invention allows the water from the washing and forming belt to flow into a water tank, where it is filtered through a filter screen in the middle and then recycled. This reduces water consumption in production, lowers water costs, aligns with environmental protection principles, reduces wastewater discharge, and helps companies establish a positive social image.
[0016] This invention achieves a high degree of automation in the entire tofu skin production process, from raw material grinding to drying. Each process is closely linked, reducing manual intervention and waiting time. The tofu skin can pass through each piece of equipment quickly and continuously, meeting the needs of large-scale production. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1-5This utility model provides a technical solution: an automated integrated equipment for the entire process of dried bean curd production, including a frame 1, with forming belts 2 slidably connected to the inner surfaces of both sides of the frame 1. From left to right, the upper end of the frame 1 is equipped with a spray pipe 3, a cutting wheel 4, a grooved roller 5, a pressing roller 6, a cutting knife 7, and a drying box 8. The spray pipe 3 is connected to a boiling pot 9 through a pipe, and a pressure pump 10 is installed on the pipe. The inlet of the boiling pot 9 is connected to a grinding machine 11 through a pipe. A heating base 12 is fixedly installed on the lower outer surface of the boiling pot 9. A rotating shaft 13 is provided on the inner side of the boiling pot 9. The upper end of the rotating shaft 13 is connected to a motor 14 located at the upper end of the boiling pot 9, and a spiral impeller 15 and a scraper 16 are fixedly connected to the outer wall of the rotating shaft 13. Made of 304 stainless steel, it features high temperature resistance and corrosion resistance, and its operating speed can be precisely controlled by a variable frequency motor. Two scrapers 16 are vertically installed inside the cooking pot 9. One side is fixedly connected to the rotating shaft 13 via a crossbar, and the other side is tightly attached to the inner wall of the cooking pot 9. The rotating shaft 13 drives the scrapers 16 to rotate, scraping off the soy milk adhering to the inner wall of the cooking pot 9, ensuring full utilization and uniformity of the soy milk in the pot. The spray pipe 3 is located at the upper end of the forming belt 2, and multiple fan-shaped nozzles are installed at its bottom. A heating plate 22 is located below the forming belt 2. The heated and stirred soy milk in the cooking pot 9 is pushed to the spray pipe 3 through the pipe under the action of the pressure pump 10. The spray pipe 3 is located directly above the forming belt 2, and its multiple fan-shaped nozzles spray the soy milk in a uniform fan-shaped pattern, covering the upper surface of the forming belt 2. The heating plate 22 located below the forming belt 2 heats the soy milk on the forming belt 2 evenly. During the movement of the forming belt 2, the water in the soy milk slowly evaporates, and the protein and other components gradually gather and solidify, thus slowly forming a bean curd sheet. The two ends of the cutting roller 4, the grooved roller 5, and the pressing roller 6 are rotatably connected to supports, and the bottom of the supports is fixedly installed on the upper end of the frame 1. As the formed bean curd sheet moves with the forming belt 2, it passes the bottom of the cutting roller 4, causing the cutting roller 4 to rotate and cut the bean curd sheet into several strips. The cut bean curd sheet enters the grooved roller 5, where it is gathered by the grooves on the roller 5, and then pressed onto the upper end of the forming belt 2 by the pressing roller 6. The gathered bean curd sheet moves to below the cutting blade 7, which is controlled by a pneumatic pump to extend and retract, cutting the bean curd sheet to form dried bean curd sticks. The cut dried bean curd sticks enter the drying chamber 8 with the forming belt 2, where they are preheated and dried to a certain degree of dryness, forming dried bean curd sticks.
[0025] In this embodiment, as Figure 4 and Figure 5As shown, a water tank 17 is fixedly installed at the bottom of the frame 1, and a nozzle 20 is provided at the bottom of the forming belt 2. The nozzle 20 is connected to the water tank 17 through a water pipe 18, and a water pump 19 is installed on the water pipe 18. The water pump 19 provides pressure, causing water in the water tank 17 to enter the nozzle 20 through the water pipe 18 and be sprayed from the nozzle 20 to the bottom of the forming belt 2 to rinse the slurry adhering to the upper end of the forming belt 2. A filter screen 21 is horizontally installed in the middle of the inner side of the water tank 17, and the connection between the water pipe 18 and the water tank 17 is close to the water tank 17. The rinsed water flows into the water tank 17, is filtered by the filter screen 21 to remove residue, and the filtered water is recycled through the water pipe 18.
[0026] Working principle:
[0027] After soaking, the raw materials are ground into soy milk by a grinder 11, and then the soy milk flows into a cooking pot 9 through a pipe. A heating base 12 at the bottom of the cooking pot 9 heats the soy milk, while a motor 14 drives a rotating shaft 13 to rotate. A spiral impeller 15 fixed to the outer wall of the rotating shaft 13 rotates accordingly, stirring the soy milk in the cooking pot 9 to prevent sedimentation or uneven dispersion, thus avoiding affecting the spraying effect and the quality of the tofu skin. The heated and stirred soy milk in the cooking pot 9 is then pushed through a pipe to the spray pipe 3 under the action of a pressure pump 10. The spray pipe 3 is located directly above the forming belt 2, and a heating plate 22 is installed below the forming belt 2 to evenly heat the soy milk on the forming belt 2. During the movement of the forming belt 2, the water in the soy milk slowly evaporates, and the protein and other components gradually gather and coagulate, thus slowly forming tofu skin. The formed tofu skin moves with the forming belt 2, and when it passes the bottom of the cutting wheel 4, it drives the cutting wheel 4 to rotate, cutting the tofu skin into several strips. After being cut, the bean curd sheets enter the grooved roller 5, where they are gathered by the grooves on the roller 5. The gathered bean curd sheets are then moved along the forming belt 2 to below the cutting blade 7. The cutting blade 7 is controlled by a pneumatic pump to extend and retract, cutting the bean curd sheets. The cut bean curd sheets then enter the drying chamber 8 along with the forming belt 2. The drying chamber 8 preheats and dries the bean curd sheets to a certain degree of dryness, forming them into bean curd sticks. The water tank 17 is connected to the nozzle 20 at the bottom of the forming belt 2 via a water pipe 18. A water pump 19 is installed on the water pipe 18. The water pump 19 provides pressure, causing water from the water tank 17 to enter the nozzle 20 through the water pipe 18. The water is sprayed from the nozzle 20 onto the bottom of the forming belt 2, rinsing off the slurry adhering to the upper end of the forming belt 2. The rinsed water flows back into the water tank 17, is filtered through the filter screen 21 to remove residue, and the filtered water is recycled through the water pipe 18.
[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
