Ultrafiltration device for enzyme preparation

Abstract

The ultrafiltration device comprises a cylinder body, a filter element, a pressure control component, blades, a liquid outlet pipeline, a slag discharge pipeline, a feed pipeline and a gas pipeline, wherein the filter element is fixedly arranged inside the cylinder body; two ends of the cylinder body are in rotating connection with the gas pipeline and the slag discharge pipeline respectively; theinner wall of the cylinder is provided with the blades; a motor is connected with the cylinder body through a transmission device and is used for driving the cylinder body to rotate; the pressure control component communicates with the gas pipeline; the feed pipeline is arranged inside the gas pipeline in a sleeved manner; the slag discharge pipeline is connected with the outlet of the cylinder body; the liquid outlet pipeline communicates with the liquid outlet of the filter element and is arranged in the slag discharge pipeline in a sleeved manner; the feed pipeline is fixedly connected with the filter element; a feeding port is formed in the feed pipeline, and communicates with the interior of the cylinder body; and the gas pipeline communicates with the interior of the cylinder body;and the feed pipeline is arranged in the gas pipeline in a sleeved manner. The ultrafiltration device can solve the problems that an existing ultrafiltration device is small in pore size of an ultrafiltration membrane and is easily blocked when being not washed for a long time, and can effectively improve the production efficiency for the separating and concentrating processes of an enzyme preparation.

Description

technical field [0001] The invention relates to the technical field of enzyme preparation processing, in particular to an ultrafiltration device for enzyme preparation. Background technique [0002] In recent years, in the production of liquid enzyme preparations, membrane separation technology has been used for dehydration and concentration, and good benefits have been achieved. The membrane separation technology is used to concentrate and refine the enzyme, the operation process is simple, the chance of bacterial contamination and enzyme inactivation is reduced, the recovery rate of the enzyme is improved and the quality of the product is improved. The molecular mass of commonly used enzyme preparations is between 10,000Da and 100,000Da. This range is just within the range of ultrafiltration technology. The crude enzyme liquid is treated by ultrafiltration technology, and low molecular substances and salts can pass through the membrane pores together with water. removed, ...
