Description

Lost grain double-round fermentation humus preparation production system

Technical Field

The utility model belongs to the technical field of making wine technology, concretely relates to in a wretched state fermentation processing system is lost at bottom of double round.

Background

The waste lees are main by-products in the wine production, the starch content in the waste lees is 10 to 12 percent, and the waste lees are rich in cellulose, protein, fat and other available organic matters. According to statistical data, the Chinese liquor brewing industry generates about 2500 ten thousand tons of waste lees every year. The distilled grain of the white spirit has high water content and high acidity, is easy to mildew and rot during stacking and storage, and can cause serious environmental pollution if being discarded or burnt randomly. The full utilization of the nutrient components in the waste lees can not only solve the environmental protection problem and save the grain, but also improve the economic benefit.

Method for treating waste lees at present

(1) For animal farming or biofertilizers: the waste lees are directly sold as feed, so the economic benefit is low, if the waste lees cannot be treated in time, the waste lees are extremely easy to rot and mildew, and the production environment of a factory is seriously influenced;

(2) raw materials for producing the health care product are as follows: the waste lees can be used as biological culture raw materials, such as high-protein edible maggot food, etc.

(3) Used as raw material of biological feed: the white spirit waste lees is used as a main raw material and is subjected to synergistic fermentation of multiple strains such as aspergillus niger, trichoderma viride, candida tropicalis and the like, and a culture contains a large amount of beneficial active thalli, microbial enzymes and other bioactive substances, and crude fibers are degraded, so that the content of crude proteins and true proteins is improved. The waste lees fermented biological feed has good economic benefit, but needs to be cultured independently, and has higher requirements on control conditions, higher production difficulty and higher production cost.

(4) For fermenting spent grain wine: most of residual starch in the distilled grain of the white spirit is low-grade dextrin which is difficult to be saccharified by enzyme, and the distilled grain has high acidity and more reducing substances, so that the propagation and fermentation of saccharification and other microorganisms such as bacteria and saccharomycetes are hindered. At present, the high-activity saccharomyces cerevisiae is still used in a plurality of white spirit factories for producing vinasse wine. The single active dry yeast is matched with the saccharifying enzyme to ferment the waste lees, only the starch in the waste lees is utilized more, the substances such as protein, cellulose and the like cannot be effectively utilized, and meanwhile, the excessive protein and cellulose substances can block the release and decomposition of the starch in the waste lees, so that the wine is influenced, and the wine body has a thinner taste. The requirements of various waste lees of different factories on fermentation yeasts are higher and higher, and the mixed fermentation of multiple enzyme systems and multiple strains becomes the research direction.

The residual starch and flavor substances in the spent grains can be used as raw materials and flavor substances of white spirit production, the spent grains are widely used for producing the spent grain wine, the process technology is mature, but the following problems are often encountered in the specific production process:

(1) the starch is utilized more importantly, and the utilization of substances such as acid, protein, amino acid and the like in the waste lees is neglected;

(2) the type, the number and the activity of the microorganisms of the distiller's grains yeast produced by the traditional method are difficult to control accurately, and the industrialization of the production is severely restricted.

(3) Although the utilization efficiency of the spent grains is improved to a certain extent by matching auxiliary materials such as saccharifying enzyme, dry yeast, complex enzyme and the like, the auxiliary materials are various in types and complex in proportion, and the production control difficulty is increased.

With the application of modern molecular biology technology, microbial breeding technology and microbial population analysis technology in white spirit research, the development of the traditional white spirit industry is promoted, and the industrial upgrading of white spirit enterprises is accelerated. Aiming at the technical difficulties encountered in the industrial production of the waste lees of the white spirit, the new technical means helps to solve the practical production problem well.

The humus is an organic matter with a complex structure in the pit mud, is not only a main source of microbial nutrition in the pit mud, but also plays an important role in maintaining the nutrition of the pit mud, adjusting the acidity and maintaining the moisture of the pit mud, and generally occupies 50-70% of the total amount of the organic matter. The main components of humus are carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, etc. Humus is not a single organic compound, but a mixture of a series of organic compounds that have both common and different compositions, structures and properties, with humic and fulvic acids being the main components. Humic acid is a humic substance which can be dissolved in an alkali solution and precipitated by an acid solution, the molecular weight of the humic acid is larger than that of fulvic acid, and the percentage content of each element in the molecular composition is as follows: c (50-60%), H (2.8-6.6%), O (31-40%) and N (2.6-6.0%). The humic acid has smaller acidity than fulvic acid, is slightly acidic, has higher absorption capacity, monovalent salts of the humic acid are dissolved in water, and divalent and trivalent salts of the humic acid are not dissolved in water, and the humic acid has important significance for maintaining soil nutrients and forming soil structures. Fulvic acid is a humic substance which is soluble in both an alkali solution and an acid solution, and has a molecular weight smaller than that of humic acid, and the percentage contents of elements in the molecular composition are as follows: c (40% -52%), H (4% -6%), O (40% -48%), N (2% -6%). The fulvic acid is strong in acidity, large in mobility and lower in absorptivity than humic acid, and its monovalent, divalent and trivalent salts are all dissolved in water, so that the fulvic acid has important action for promoting mineral decomposition and nutrient release. The humus can exist in clay in a free humic acid and humic acid salt state, and can also be in a gel state to be tightly combined with mineral clay grains to become an important colloidal substance.
