Description

Technical Field

[0001] The invention relates to the technical field of tofu production and processing, and in particular to tofu residue slurry residue separation equipment and a working method thereof. Background Art

[0002] Tofu sludge refers to the residue remaining after filtering out the soy milk during the process of making tofu or soy milk. Specifically, tofu sludge is the solid residue obtained by filtering the soy milk when making soy milk, usually called dregs. The impurities and coarse dregs in the soy milk can be removed by sludge separation equipment, making the tofu taste more delicate and tender. In addition, the separated soy milk is purer, which is conducive to the coagulation and molding of tofu, thereby improving the quality of tofu.

[0003] The currently used pulp-residue separation equipment mostly uses a circular vibrating screen to separate the dregs and soy milk. The dregs and soy milk are separated by vibration. However, the screen is easily clogged after being used for a period of time, and some small particles of dregs are easily retained by the filter, resulting in an insufficient separation effect. In addition, additional manpower is required to clean the filter, which reduces the separation efficiency. Summary of the invention

[0024] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0025] 1. Pour the tofu dregs into the filter cartridge, turn on the servo motor, and with the cooperation of the belt, the first pulley and the second pulley, drive the shaft and the top filter cartridge to rotate, and use centrifugal force to separate the dregs from the soy milk. After using it for a period of time, control the filter cartridge to stop rotating, and move the lever to the other side to drive the partition to rotate, so that the notch in the partition corresponds to the air nozzle, and then turn on the air pump to spray high-pressure gas through the air nozzle to back-blow the stainless steel filter on the inner wall of the filter cartridge, so as to blow out the small particles of bean dregs blocked in the stainless steel filter, so as to continue to use it, avoid affecting the subsequent pulp-dregs separation due to filter blockage, improve the separation efficiency, and solve the problem that the screen is easily blocked after a period of use, resulting in poor separation effect, and additional labor is required to clean the filter, which reduces the separation efficiency.

[0026] 2. By setting a rotatable partition in the middle position of the filter cartridge and the air nozzle, when the filter cartridge rotates, the notch in the partition is misaligned with the air nozzle, which helps to avoid the filtered soy milk from spilling into the air nozzle and affecting the normal use of the air nozzle.
