Method for ecological conversion of fen-flavor white spirit vinasse musca domestica larva

Abstract

The invention discloses a method for ecological conversion of fen-flavor white spirit vinasse musca domestica larva. The method comprises the following steps: musca seed collection, clean raising and domestication, induction and stabilization to fen-flavor white spirit vinasse conversion and adaptation flies, preparation of industrialized fly maggot protein production basic charge, induction and stabilization to cellulose high-expression flies, stabilization to fen-flavor white spirit vinasse production flies, as well as the production of fly maggot industrial products. Compared with the prior art, the invention adopts biotechnology for seed corn maggot vinasse ecological converting function induction and screening, transfer of culture and engineered feeding, adopts modernized engineering technology to achieve vinasse resourced governing by taking house fly treating supersession as the main can be achieved, and has the advantages of high degree of ecologicalization, high bioavailability, short thoroughly decomposed period (about seven days), diversification of product, high quality, high added value of resources, zero discharge of production, zero environment pollution, scientific matching, high fertilizer effect and the like.

Description

technical field [0001] The invention relates to a method for ecological transformation of housefly larvae by discarding lees of fragrant liquor, belonging to the technical field of housefly breeding and lees treatment. Background technique [0002] Liquor industry is an important economic category in my country and is closely related to agriculture; the current output has reached 8.908 million tons per year, which is mainly divided into three categories: strong flavor, Maotai flavor and light flavor, of which Maotai flavor accounts for 10%, strong flavor 70% of the type, 15% of the fragrance type, with an annual output of more than 30 million tons of waste. How to scientifically recycle the waste of liquor and develop raw material production is a common problem in the clean production and sustainable development of liquor. [0003] Liquor brewing uses sorghum, corn, rice and other food crops as the main raw materials, so there is a large amount of rice husks in the discarded...

AI Technical Summary

Problems solved by technology

However, my country's liquor production adopts a multi-strain mixed solid-state open fermentation method, which is a unique brewing process unique to my country, which has high requirements for the micro-ecological environment of the wine-producing area, and the use of microbial methods to treat liquor waste It is often necessary to introduce new dominant strains of foreign microorganisms, which will easily destroy the original microbial balance of the winemaking area, and have the risk of affecting the unique regional flavor of liquor formed by the open multi-strain mixed solid-state fermentation of Chinese liquor

Moreover, the microbial treatment method has a relatively long fermentation period, generally 30-40 days; the resulting product is relatively single, and the added value of the product is low

[0008] 3. Distiller's grains are treated as industrial raw materials: such as the comprehensive utilization method of Luzhou-flavor liquor discarded grains adopted by Wuliangye Group CN101565187B, the discarded grains are dried and screened, and the rice husks on the sieve are used as fuel, and the burned rice husk ash It is used to produce white carbon black, and the sieved material is used as animal feed. The disadvantage is also the loss of nutrients during the drying process, and the white carbon black industry is a high-energy, high-pollution industry restricted by the state. The environment will inevitably have a certain impact

Wuliangye Group is the largest Luzhou-flavor liquor brewing enterprise in my country. The husk content in distiller’s grains is very high, about 60%, and its annual distiller’s grains can only produce about 4,000 tons of white carbon black. Therefore, although this technology produces Silica is low in cost, good in quality, and has a certain market prospect, but it is not suitable for popularization and application due to the problem of output, and it does not conform to the policy orientation of the national industrial structure adjustment of energy conservation and emission reduction

But the inventor's research shows that: there are many kinds of wine, and the quality of various distiller's grains is also very different due to the difference in raw materials and brewing methods of wine making, and the natural adaptability of housefly is also different.

Cultivate housefly larvae with distilled grains. Due to its high alcohol content, high acidity, and harmful substances such as ethyl acetate and ethyl caproate, the hatching of the fly eggs is slow, the hatching rate is low, and the mature worms are small. poor conversion efficiency

Another scholar reported that only 230 grams of housefly larvae can be obtained per 10 kilograms of wine discarded grains under the condition of adding water to dilute to a water content of 85%, and such cultivation of fly maggots will produce a large amount of sewage, causing environmental problems

At present, there is no relevant technical report on the use of insects for efficient ecological transformation of liquor discarded grains
