Method for producing ethanol and cultivating edible mushroom with manioc waste

Abstract

The invention discloses a method of utilizing cassava dregs to produce alcohol and cultivate edible fungus, which is characterized in that after the cassava starch dreg is dried in the sun or squeezed and baked, mixing with material, steaming, first cooling, saccharifying enzyme, secondary cooling and adding yeast, pit fermentation and distilling in steam cooker is carried out, then firstly the thin alcohol produced is stored in a rectifying column, distilled and cooled for producing end product alcohol; secondly the cassava starch dreg after distillation in steam cooker is cooled, prepared and fermented secondarily to become the nutritious culture medium of edible fungus, then strain of good quality is inoculated into the culture medium to cultivate organic product of edible fungus. The invention is a method of carrying out the intensive processing of the cassava dregs and realizing the multipurpose utilization of one material and making waste profitable as well as developing circular economy, and has the advantages of solving the environmental pollution problem from starch pulp, saving food resources, the low production cost, realizing the circular economy, having many kinds of cultivated edible fungus, not adding any fertilizer and meeting the green food standards, and being especially suitable for the wide range and large scale planting of Agaricus bisporus.

Description

Technical field: [0001] The invention relates to waste utilization and environmental protection technology, in particular to a method for producing alcohol and cultivating edible fungi by using cassava residue. Background technique: [0002] In my country, the raw materials for ethanol production are mainly corn, potatoes, sorghum and other food crops. With the increase in the demand for alcohol and the gradual popularization of fuel ethanol, food raw materials are showing unprecedented tension in a populous country like my country, and their prices have skyrocketed. For example, CCTV's 2007 continuous report "Corn Crazy" shows its great influence. [0003] In terms of edible fungi, in the traditional cultivation methods of edible fungi, especially the cultivation of Agaricus bisporus series edible fungi, the main cultivation base materials are straw, cow dung, cotton, etc. Along with the enlargement of edible fungus cultivation area, raw material resources such as cow dung ...

AI Technical Summary

Problems solved by technology

With the expansion of edible fungus cultivation area, raw material resources such as cow dung are insufficient. In addition, using the above-mentioned method to mix mushroom farmers is labor-intensive, and the production sanitation conditions are poor and the environment is not good.

[0004] In my country, although the technology of using cassava starch slag "raw material" to cultivate edible fungi has long been used, its technology is very primitive and backward, and it needs to add a lot of phosphorus, multi-element potassium fertilizers, etc., and also need to add crop straw, bagasse, rice, etc. Hull, cottonseed, etc., its disadvantages are high labor intensity, high planting cost, low utilization rate of nutrients in cassava dregs, high dependence on fertilizers, low fruiting rate, and low nutritional protein content of mushrooms produced, which cannot reach the level of green food Standard, not suitable for large-scale planting, not up to the international standard of industrialization
