Efficient alcohol production process through thinning of bamboo bran

Abstract

The invention provides an efficient alcohol production process through thinning of bamboo bran. The efficient alcohol production process comprises: by adopting 100 as a base rate, weighing bran, lime and purified water according to a ratio of 5-7:0.5-0.7:7-9, thinning to obtain a slurry-like raw material, respectively weighing the slurry-like raw material, alcohol koji and purified water according to a ratio of 100:0.9-1.1:280-300 and different temperatures, uniformly stirring, pouring into a tank, carrying out anaerobic fermentation for 11-13 days, pouring into distillation equipment at the 15th-17th days after the mash is mature, and timely carrying out heating distillation to obtain required ethanol, wherein the filtrate can be used for the next raw material fermentation or livestock feed fermentation, the remaining residue and a biochemical agent are weighed according to a ratio of 9-8:2-1, are uniformly stirred, and poured into a biogas tank to produce biogas, the obtained biogas and a condensing agent are weighed according to a ratio of 8-6:0.003-0.001, are mixed, and are filled into a tank so as to be spare, the remaining residue and plant sticky juice are weighed according to a ratio of 7-5:0.2-0.5, are uniformly stirred, and are pressed into the special fuel block for the biochemical furnace or are prepared into the plate.

Description

technical field

[0001] The invention relates to a process for producing alcohol, in particular to a process for refining and high-efficiency alcohol production from bamboo and wood bran.

[0002] technical background

[0003] In today's world, energy has become a major strategic resource and decision-making basis for the economic and political development and competition of various countries, and ethanol is prominent in energy resources, but as the main resource of ethanol, coal, oil, natural gas and other reserves are extremely limited and easily depleted. And the cost of mining and use is large and easy to damage the ecological environment. Therefore, it is extremely necessary to further study the utilization of a large number of waste bran resources to optimize and efficiently develop new energy, which is particularly important and urgent for production, work and life.

Examples

Embodiment 1

[0016] Example 1: Take 100 as the base rate, weigh 500 kg of bran, 50 kg of lime, and 700 kg of purified water according to the ratio of bran raw meal, quicklime, and purified water as 5-7: 0.5-0.7: 7-9, and put them in order Soak the bran in the soaking tank to remove alkali for 16-20 days, then remove the bran, clean it and put it into a grinder to pulverize and refine it into a slurry-like raw meal;

[0017] Then take 100 as the base rate, mix the pulverized bran slurry raw meal according to raw meal: alcohol koji: clean water = 100: 0.9: 280, when the temperature is higher than 30°, use koji 0.9 and add water 300, and weigh 10000 kg of raw meal respectively , 90 kg of alcohol koji, 28,000 kg of clean water and put them into a fermentation tank or a pool to stir the mash evenly with a mixer, then seal the tank or the mouth of the pool for anaerobic fermentation, and stir it once every 3 days or so, until 11 days, After all the raw material mash floats up, after 15 days all ...

Embodiment 2

[0020] Embodiment 2: Take 100 as the base rate, weigh 600 kg of bran, 60 kg of lime, and 800 kg of purified water according to the ratio of bran raw material, quicklime, and purified water to 6:0.6:8, and put them into the soaking tank successively to remove the bran. Soak for alkali removal for 18 days, then remove the bran and put it into a grinder to pulverize and refine it into pulpy raw meal;

[0021] Then take 100 as the base rate, mix the pulverized bran slurry raw meal according to raw meal: alcohol koji: clean water = 100: 1: 290, add water 290 with koji 1 when the temperature is lower than 30°, and weigh 10000 raw meal respectively. kg, 100 kg of alcohol koji, 29000 kg of clean water and put them into the fermenter or pool to stir the mash evenly with a mixer, then seal the tank or pool mouth for anaerobic fermentation, and stir once every 3 days or so, up to 12 days , when all the raw material mash floats up, all the mash sinks after 16 days, and the fermentation is...
