Concentration technology for zymogen liquid

Abstract

The invention discloses a concentration technology for zymogen liquid. The concentration technology adopts macromolecule polyacrylonitrile fiber hollow film filter tube combined equipment as concentration equipment and depends on the pressure difference of an inlet and an outlet, zymogen liquid with lower concentration continuously and circularly flows in a film processor comprising unnumbered fiber film tubes, water continuously leaks out from millipores of the walls of the fiber film tubes, and finally the purpose of concentration can be achieved; and during backwashing, the fiber film tubesare processed by reverse washing by cleaner, substances piled around the millipores of the film tubes in the original concentration and filtration are cleanly washed, and film processing equipment can be guaranteed to be regenerated. The invention is the concentration technology for the zymogen liquid, having the advantages of simplicity, high reliability, easy running operation, low overhaul andmaintenance, reasonable structure of products, and high safety, economy, durability, concentration efficiency of the zymogen liquid and production efficiency.

Description

technical field [0001] The invention relates to a process for concentrating fermented bacterial liquid, in particular to an industry innovation in which high molecular weight polyacrylonitrile fiber hollow membrane filter tube assembly equipment is used as the concentrating equipment. Background technique [0002] At present, the commonly used fermentation liquid concentration methods include high-speed centrifugal concentration method, plate-and-frame filter dehydration concentration method, vacuum scraper concentration method and freeze-drying method concentration method, but most of these concentration methods have long concentration time, low production efficiency, and require large-scale production. Professional equipment and other problems, and the key steps require manual operation, it is difficult to produce continuously; the filter holes of the plate and frame filter are much larger than the bacteria, and the collection rate of the bacteria is low. Contents of the ...
