Embodiment 1

[0030] Aspergillus niger (Aspergilus niger, AN) is added to the culture medium and placed in a greenhouse at 25-35℃ for 1-2 days. Per liter of culture medium starch accounts for 20-30 grams, peptone 20-30 grams, sucrose or glucose 20-30 grams, 5-10 grams of sodium chloride, add distilled water to make it reach 1 liter, and then acclimate to the fermentation concentration of yellow pulp water for another day (the temperature and other conditions remain unchanged) after the culture, and it is best to add manganese during the culture process Water-soluble inorganic salts of iron, zinc, antimony and tin, the added amount of manganese salt accounts for 0.5-2% of the mass percentage of the culture medium; iron salt accounts for 2-5% of the mass percentage of the culture medium; zinc salt accounts for the culture 1-2% of the base mass percentage; antimony salt accounts for 0.2-1% of the medium mass percentage; tin salt accounts for 0.3-1 of the medium mass percentage, 30 kg of fermented ...

Embodiment 2

[0032]Kluyveromyces (Kluyveromyces), Trichoderma Koningii (Trichoderma Koningii) were first added to the culture medium and placed in the greenhouse at 25-35 ℃ for 1-2 days, each liter of culture medium starch accounted for 20-30 grams, peptone 20-30 grams of sucrose or glucose, 20-30 grams of sodium chloride, 5-10 grams of sodium chloride, add distilled water to make it reach 1 liter, after incubation, it will be acclimated for another day according to the fermentation concentration of yellow pulp water, (temperature and other conditions Unchanged) It is better to add water-soluble inorganic salts of manganese, iron, zinc, antimony and tin during the cultivation process. The amount of manganese salt added accounts for 0.5-2% of the mass percentage of the medium; iron salt accounts for the mass percentage of the medium. 2-5%; zinc salt accounts for 1-2% of the medium mass percentage; antimony salt accounts for 0.2-1% of the medium mass percentage; tin salt accounts for 0.3-1 of th...

Embodiment 3

[0034] Erwinia (Erwinia), Trichoderma reesei Rut C-30 (Trichoderma reesei Rut C-30) were added to the culture medium and placed in the greenhouse at 25-35℃ for 1-2 days, and each liter of culture medium starch accounted for 20-30 Grams, 20-30 grams of peptone, 20-30 grams of sucrose or glucose, 5-10 grams of sodium chloride, add distilled water to make it reach 1 liter, after incubation, it will be acclimated for another day according to the fermentation concentration of yellow pulp water, ( Conditions such as temperature remain unchanged) During the cultivation process, it is best to add water-soluble inorganic salts of manganese, iron, zinc, antimony and tin, and the amount of manganese salt added accounts for 0.5-2% of the mass percentage of the medium; iron salt accounts for 100% of the mass 2-5% of the medium content; zinc salt accounts for 1-2% of the medium mass percentage; antimony salt accounts for 0.2-1% of the medium mass percentage; tin salt accounts for 0.3- of the me...

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

Technical field [0001] The invention relates to a method and equipment for fermenting and producing alcohol using starch as a raw material. Especially on the basis of traditional alcohol production technology and equipment, methods and equipment that use biotechnology to greatly improve alcohol productivity. Background technique [0002] At present, the annual output of alcohol in my country is about 3 million tons, mainly produced by fermentation. With the development of economy, the progress of science and technology and the increase of scientific research investment, although the alcohol production technology has achieved low temperature cooking, raw starch alcohol fermentation, continuous fermentation of immobilized cells, breeding of high temperature resistant alcohol yeast, differential pressure distillation, etc. A gratifying achievement; however, problems such as backward production technology, low alcohol yield, low comprehensive utilization of resources, and serious env...
