Beta-amylase production system and production process thereof

Abstract

The invention relates to the technical field of biological enzyme preparations, in particular to a beta amylase production system and a production process thereof. The beta-amylase production system comprises a size mixing process, a filtering process, a concentration and impurity removal process, an enzyme liquid stabilizing process and a material residue treatment process. Wherein in the filtering process, a plate-and-frame filter press is used for carrying out filter-pressing separation on feed liquid; grooves, through grooves, push blocks, pull blocks, first springs and second springs are arranged on the filter plate of the plate-and-frame filter press, in the extrusion process of the filter plate, the push blocks located at the four opposite angles of the filter plate slide downwards along the first grooves, the push blocks push the pull blocks to slide outwards along the through grooves in the downward sliding process, and in the outward sliding process of the pull blocks, the pull blocks are pushed to slide outwards along the through grooves. The drag hooks drive the filter cloth to expand outwards, so that the filter cloth is tensioned outwards along the four corners of the filter plates, the filter cloth is automatically leveled in the pressing process, and the situation that the leakage amount of mixed liquid between the filter plates is large due to the fact that the filter cloth is wrinkled in the pressing process is prevented.

Description

technical field [0001] The invention relates to the technical field of biological enzyme preparations, in particular to a β-amylase production system and a production process thereof. Background technique [0002] β-amylase, also known as starch 4-maltosidase, is a kind of amylase, which widely exists in higher plants such as barley, wheat, sweet potato, soybean, and microorganisms such as Bacillus. It is the main saccharification agent for beer brewing and caramel (malt syrup) production. High maltose syrup with a maltose content of 60%-70% can be produced by using β-amylase saccharification and acidification or α-amylase liquefaction starch raw materials produced by microorganisms such as Bacillus polymyxa and Bacillus megaterium. [0003] At present, the β-amylases used in the food industry mainly include plant β-amylases and microbial β-amylases. Due to the relatively low activity of β-amylases produced by microbial fermentation, poor heat resistance, low enzyme product...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, for the plate and frame filter press in the β-amylase production system in the prior art, during the automatic compaction process, the filter cloth and the sealing surface of the filter plate are not well bonded, which is easy to cause the filter cloth to be damaged. There are wrinkles on the sealing surface after compression, and the leakage of the filter plate medium after feeding is larger than normal, which makes the filter press effect worse. On the other hand, during the filter press process, the material slag in the feed liquid often accumulates And be pressed into a filter cake tightly adhered to the filter cloth, the existing way of cleaning the filter residue is manual cleaning, the cleaning efficiency is low and the labor intensity of the workers is high. The present invention proposes a β-amylase production system and its production process
