Biological enzyme liquid/beverage multistage ultrafiltering-purifying-separating-concentrating device

Abstract

The invention relates to a biological enzyme liquid / beverage multistage ultrafiltering-purifying-separating-concentrating device which comprises a raw material storage tank, a plate-type ultrafilter, a tubular ultrafilter, a filtrate gathering tank, a cam pump, a liquid pump, a flow regulator and a flowmeter, wherein a refrigeration coil of a refrigeration system is respectively arranged in the raw material storage tank and the filtrate gathering tank. By combining the plate-type ultrafiltering / tubular ultrafiltering multistage structures connected in parallel / series, arranging the multistagefiltering-concentrating devices and the close-type ultrafiltering system and matching with a perfect regeneration system, the ultrafiltering-separating device can operate at 5-35 DEG C so as to reduce the loss of enzyme activity and obtain a target product which is concentrated to the required concentration. In the process of filtering and concentrating, the plate-type ultrafiltering system or tubular ultrafiltering system is started according to the filtering level requirement to carry out single-stage or multistage filtering and concentrating, thereby obtaining the target product. The flow rate is regulated by frequency variation, so that the back flow circulating liquid and the permeation water can be used for implementing both separation of micromolecular substances and liquid concentrating, and continuous high-efficiency filtering can be implemented without choking the ultrafiltering tube, thereby enhancing the ultrafiltering treatment capacity, lowering the cost and increasing the yield.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to equipment for concentrating and separating biological enzyme liquid and beverage extract, in particular to a multi-stage ultrafiltration purification, separation and concentration device for biological enzyme liquid and beverage. Background technique [0002] Due to the quality of biological enzyme preparations, beverages, solvents and other fields, the quality of products is easily limited by temperature, so the traditional high-temperature evaporation concentration method is not suitable for the concentration of liquid products such as biological enzyme preparations, beverages, etc., while the vacuum freeze concentration method, reverse osmosis concentration The cost of the method is very high, especially the concentration of food-grade enzyme preparations has higher requirements on the concentration technology, which not only requires a small loss of enzyme activity in the concentrat...

[0002] Due to the quality of biological enzyme preparations, beverages, solvents and other fields, the quality of products is easily limited by temperature, so the traditional high-temperature evaporation concentration method is not suitable for the concentration of liquid products such as biological enzyme preparations, beverages, etc., while the vacuum freeze concentration method, reverse osmosis concentration The cost of the method is very high, especially the concentration of food-grade enzyme preparations has higher requirements on the concentration technology, which not only requires a small loss of enzyme activity in the concentration process to obtain a high-activity biological enzyme concentrate, but also requires a completely pollution-free concentration process. Therefore, at present The practicability of various enrichment equipment is not strong
