Feed liquid filtering system for producing premna microphylla tofu

Abstract

The invention belongs to the processing field of premna microphylla, and particularly relates to a feed liquid filtering system for producing premna microphylla tofu. The feed liquid filtering system comprises a filtering plate, and filtering holes are evenly distributed on the filtering plate; the upper surface of the filtering plate is paved with a filtering cloth, and the lower part of the filtering plate is provided with a liquid storage tank; the upper part of the filtering plate is further provided with a moving frame, and the moving frame is arranged along a vertical direction in the manner of reciprocating motion; a scraper blade capable of performing the reciprocating motion along the horizontal direction is arranged on the moving frame, at least one side on the moving frame in parallel to the scraper blade is provided with a dump tank, and the inside tank wall of the dump tank is bonded to the edge of the filtering plate; when the moving frame is located at the upper part, the upper end of the inside tank wall of the dump tank is higher than the upper surface of the filtering plate; when the moving frame is located at the lower part, the upper end of the inside tank wall of the dump tank is lower than the upper surface of the filtering plate or leveled to the upper surface of the filtering plate. During the filtering process, the scraper blade can intermittently clean the filtering cloth, prevent the filtering slag in the slurry from blocking sieve holes and making the filtering cloth keep good throughput capacity; a vacuumizer can make the liquid storage tank under negative pressure state, thereby generating a certain suction to pectin and further improving the filtering efficiency.

Description

technical field [0001] The invention belongs to the field of tofu wood leaf processing, and in particular relates to a material-liquid filtration system for producing Guanyin tofu. Background technique [0002] Doufuchai is also known as tofu wood, Guanyinchai, etc. The large amount of pectin contained in its leaves is the main raw material for making the special food "Guanyin tofu". The "tofu" made from tofu leaves contains a lot of pectin, protein, cellulose, chlorophyll and vitamin C. It is green in color, smooth in taste and rich in nutrition. It is a pollution-free green food. The extraction of pectin from bean curd leaves is mainly divided into several processes such as rolling, crushing, and filtering. However, because the leaves contain a large amount of pectin, the residues in the filtering process can easily block the sieve holes, resulting in too slow filtration speed. or cannot be filtered.
