[0008] By adopting the above technical scheme, the buffer spiral plate in the pipeline at the bottom end of the collecting hopper can buffer the flow rate of bean milk, so that the bean milk flows uniformly into the filter slurry cylinder, and the impact on the filter screen is reduced.

[0009] Preferably, the filter cylinder side wall is equidistantly provided with four one-way pipes, and a one-way valve is arranged in the one-way pipe.

[0022] 1. Three vertically oriented interception plates are installed inside the filter cylinder. A filter screen is installed at the rectangular opening of each interception plate to form a multi-stage filtration structure. As the soybean residue, soybean skin and other impurities pass through the filter screens at each stage, they are intercepted layer by layer, improving the filtration precision and effectively removing various impurities from the soybean milk. This lays the foundation for producing high-quality, delicate-tasting and smooth-looking dried bean curd sticks.

[0023] 2. The buffer spiral plate inside the pipe at the bottom of the centralized hopper is flush with the bottom of the pipe. When the soy milk flows from the centralized hopper into the filter cylinder, the buffer spiral plate can slow down the flow rate of the soy milk, so that the soy milk is evenly distributed and flows in, avoiding the impact of the filter screen due to excessive flow rate, and extending the service life of the filter screen. At the same time, the buffer frame installed on the surface of the interceptor plate is designed as a trapezoidal block structure with an opening at the bottom, which can further buffer the impact of soy milk on the filter screen. While protecting the filter screen, it helps to maintain the stability of the filtration process and ensure the filtration effect.

[0024] 3. During the filtration process, if the pressure inside the filter cylinder increases due to the flow of soybean milk or the accumulation of impurities, the one-way valve will open to release some gas or liquid, balancing the internal pressure. The device also features a detachable installation design, which allows for easy removal of the interceptor plate for cleaning or replacement of the filter screen when it becomes clogged or damaged, reducing equipment maintenance costs and improving the ease of use and maintenance efficiency of the equipment.
