Description

Technical Field

[0001] The invention relates to the technical field of plant protein extraction equipment, in particular to a filter for flexible production of multiple types of plant proteins. Background Art

[0002] Protein is the material basis of life activities and plays an important role in regulating human physiological metabolism. At the same time, protein is also an indispensable nutrient for human life activities. In the past, people mainly used animal protein as a high-quality protein source (such as meat, milk, eggs, etc.). With the growth of population and the improvement of people's living standards, the traditional protein supply model has been difficult to meet people's daily needs, and a large amount of animal protein intake has led to an increase in the incidence of obesity, diabetes, atherosclerosis, etc. In view of the above reasons, high-protein, low-fat, cholesterol-free plant protein has gradually attracted people's attention in recent years. With the improvement of people's living standards and the need for health in my country, protein intake has become an important need, and the intake of plant protein has become an indispensable means of obtaining protein. The intake of plant protein is already a global demand.

[0003] The extraction of plant protein is a complex process. Using a fixed production line cannot meet the extraction of multiple plants, and building multiple production lines will inevitably incur huge construction costs. In response to the above problems, a flexible production process was studied, which is to divide the entire production process into process segments for block control in order to achieve control reorganization of the process segments (specifically: the technical architecture of the system is defined by a hierarchical network model based on the industrial control concept architecture. It is developed based on electrical automatic control, sequential logic control, instrument control, loop regulation and other routes; it is designed using process modularization, control system modularization, equipment modularization and batch processing methods. When the raw materials change, commands are issued through the human-machine interface, and the program automatically completes the in-situ reorganization of the process, equipment, process parameters, and control parameters, realizing automatic flexible production with raw material changes). However, when the plant material is chopped and filtered after adding buffer solution, the size of the crushed plant tissue will be inconsistent due to the inconsistent degree of crushing of various plants. It is impossible to use a screen with the same aperture for efficient screening to remove the filter residue and fixed particles. This requires replacing different filtering equipment for filtration, which reduces work efficiency and increases production costs. In addition, the existing filter screen cannot immediately discharge solid particles and impurities on the screen, affecting subsequent screening operations. Summary of the invention

At this time, the fallen solid particles and residues can slide down and fall out along the inclined sealing plate 2, or the sealing plate 2 can be controlled to restore to a vertical state, thereby discharging the solid particles and residues.

[0025] When using: 1. The effective sieve holes of the filter screen are adjusted according to the plant species from which the protein liquid is extracted. The adjustment method is as follows: two servo motors 8 are controlled to work, and the servo motors 8 drive the threaded sleeve 81 to rotate. During the rotation of the threaded sleeve 81, the screw 82 drives the push plate 83 to move, and the push plate 83 drives the movable screen 6 to move. The movable screen 6 drives the guide rod 62 to move along the guide hole 52, so that the size of the overlapping part of the lower sieve hole 51 and the upper sieve hole 61 is changed, thereby adjusting the size of the effective sieve hole; 2. Pour the homogenized plant tissue into the filter screen, and the vibrator 9 cooperates with the crossbar 7 with the spring 71 to make the filter screen reciprocate, so that the fixed particles and filter residues remain in the filter screen, and the solution containing the plant protein enters the box 1, and the plant protein solution flows along the guide plate 3 and is discharged through the discharge pipe; 3. The steps for cleaning solid particles and residues are as follows: 31. The control cylinder 21 is extended, and the cylinder 21 drives the sealing plate 2 to tilt toward the inside of the box body 1 through the connecting rod 22, so that the two sealing plates 2 are distributed in an I shape; 32. Repeat step 1 to make the lower sieve hole 51 and the upper sieve hole 61 completely overlap, and the effective sieve hole size is at the maximum state; 33. Repeat step 2 to allow the solid particles and residues to pass through the effective sieve holes and fall onto the sealing plate 2. The solid particles and residues slide down the inclined sealing plate 2 or the sealing plate 2 is controlled to restore to a vertical state, thereby discharging the solid particles and residues.
