Alcohol output increasing method and device

Abstract

The present invention relates to alcohol producing fermentation process and apparatus with starch as material. After biological enzyme active catalyst on carrier is set inside some container, turbid liquid with starch is made to stay in the container to contact with the catalyst for 30-60 min. The biological enzyme active catalyst includes pectinase in 8-15 wt%, cellulase in 10-20 wt% and trace elements, and the carrier is porous material, with the pectinase and cellulase being obtained through strain fermentation. The present invention has increased alcohol yield.

Description

Method and equipment for increasing alcohol production technical field The invention relates to a method and equipment for producing alcohol by fermenting starch as a raw material. Especially on the basis of the traditional alcohol production process and equipment, the method and equipment of greatly improving the alcohol production rate by adopting biotechnology. Background technique At present, my country's annual alcohol production is about 3 million tons, mainly produced by fermentation. With the development of the economy, the progress of science and technology and the increase of investment in scientific research, although the alcohol production technology has made great achievements in low-temperature cooking, raw starch alcohol fermentation, continuous fermentation of immobilized cells, breeding of high-temperature resistant alcohol yeast, differential pressure distillation, etc. It is a gratifying achievement; however, due to problems such as backward production t...
