Abstract

Vacuum starch extraction equipment comprises a vacuum pump, a reaction tank, an amylase storage tank and an extraction liquid storage tank. The vacuum pump is connected with the reaction tank and theextraction liquid storage tank through pipelines, the amylase storage tank is connected with the reaction tank and the extraction liquid storage tank through pipelines, and each pipeline is provided with a sealing valve; the middle upper part of the reaction tank and the middle upper part of the extraction liquid storage tank are both provided with an air outlet pipe, and each air outlet pipe is also provided with a sealing valve. The structure of the equipment has the advantages of being environmentally friendly, sanitary and capable of reusing energy, the problem that corn fiber skin starchis low in extraction efficiency in the prior art is solved, and particularly, the extraction efficiency is improved by 8 times compared with that of the prior art under the condition that the vacuum degree is 0.09 MPa.

Description

technical field [0001] The invention relates to a starch extraction device, in particular to a starch extraction device for vacuum corn fiber husks. technical background [0002] In reality, corn fiber husk is a by-product in the process of producing starch from corn. It has been found through experiments that the starch content in corn fiber husk is relatively high, and its content generally reaches 12.5% ​​of the total amount of corn. The existing batch method and water washing method are used to extract the starch in the corn fiber husk. This method consumes a lot of water and has a low yield. Especially when the concentration of the extract is about 1%, there is basically no recovery value. In order to improve production efficiency and equipment utilization, the enzymatic continuous extraction process of corn fiber husk amylase under vacuum conditions is adopted. The enzymatic continuous extraction process of corn fiber husk amylase overcomes the shortcomings of the inte...
