Finished product residual liquid recoverable post-extraction production line of enzyme preparation fermentation liquid

Abstract

The invention discloses a recovery system for a residual liquid in post-extraction filtering equipment of an enzyme preparation fermentation liquid, and solves the problems of simple and rough process as well as fermentation liquid waste in prior art. The production line of the invention is characterized in that a fermentation liquid storage tank is communicated with a plate and frame filter press, a filter pressing clear liquid storage tank, a microfiltration membrane filter, a storage tank for concentrated solution after microfiltration and ultrafiltration, and an ultrafiltration membrane filter through valves and pumps, and a sterile air branch is disposed at the outlet of the microfiltration membrane filter. The invention comprehensively adopts plate and frame filter pressing, tubularmembrane microfiltration, and rollup membrane ultrafiltration sealed filtering equipment as well as a sterile air residual liquid cleaning facility. By making fully use of the advantages of various equipment, the invention achieves substantial effects in degerming and slag removing, active ingredient purification, finished product residual liquid recovery, labor intensity reducing, as well as energy saving and emission reduction, etc.

Description

Technical field: [0001] The invention relates to a post-extraction system of fermented liquid, and more specifically relates to a post-extracted production line of enzyme preparation fermented liquid which can recover the residual liquid of finished product of filtration equipment after extraction. Background technique: [0002] The post-extraction process of the enzyme preparation fermentation liquid determines the clarity of the final product of the enzyme preparation, the purity of the active ingredients, the effect of removing slag and bacteria, and the stability of product quality, which ultimately affects whether the product has high quality and meets the requirements of higher standards. The requirements for a wide range of uses, whether the production process is energy-saving and emission-reducing, and whether it is more environmentally friendly, therefore, strengthening the research and development of the post-extraction process of enzyme preparations has important i...

AI Technical Summary

Problems solved by technology

[0003] The extraction process of traditional enzyme preparations in my country is simple and rough. Generally, plate and frame press filtration and ultrafiltration are used to concentrate. The product contains many impurities, the effect of sterilization and solid removal is poor, and the product clarity is poor. More waste residues are discharged, which is difficult to meet environmental protection requirements; high energy consumption and high labor intensity are not suitable for industrial development requirements

Moreover, after the production of conventional ultrafiltration concentration equipment is completed, a large amount of residual liquid of finished products remains in the equipment and pipelines; enzyme preparations have special effects and high value, and conventional discharge will not only cause environmental pollution but also cause waste of finished products; , The cleaning of residual liquid in the equipment will consume a lot of water, increase the amount of water and wastewater treatment, and cause unnecessary waste
