Recirculating filtration apparatus used to filter Guanyin Tofu production feed liquid

Abstract

The invention belongs to the premna microphylla processing field, specifically referring to the recirculating filtration apparatus used to filter Guanyin Tofu production feed liquid, including the filter board, the liquid storage tank under the filter board and the adjustable shelf above the filter board. The mentioned adjustable shelf makes reciprocating motion along the vertical direction with a scraper capable of moving back and forth in the horizontal direction; the slag discharge outlet connects with a settling tank through the slag discharge pipe; the settling tank is divided by the vertically set division plate on the bottom of the tank into the slag liquid pool and recycling pool; the upper end of the division plate is lower than that of the settling tank walk; the slag discharge pipe is connected to the slag liquid pool and there is a filter screen between the upper part of slag liquid pool and the corresponding location of the division plate; at the bottom of the described recycling pool, there is a return pipe with a reflux pump, which is linked with the upper part of the said filter board. During the filter process, the scraper carries out intermittent clear on the filter cloth to prevent the residue in the seriflux from blocking the sieve pore, which can keep the favorable trafficability of the filter cloth and promote the filter efficiency of the pectin.

Description

technical field [0001] The invention belongs to the field of bean curd wood leaf processing, and in particular relates to a circulating filter device for filtering feed liquid for production of 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.
