A kind of liquor lees decomposer and its preparation method and application

Abstract

The invention discloses a liqueur vinasse decomposition agent. The preparation method comprises the steps that thermoactinomyces sacchari CP with characteristics of high temperature resistance, alcohol resistance and acid and alkali resistance is scientifically compounded with existing rotten funguses, and meanwhile cellulose, xylogen, starch, protein, fat and the like in the vinasse are sufficiently degraded though the synergistic effect among different rotten funguses. Processing of alcoholic strength dropping, acidity dropping and the like of the vinasse is avoided, composting fermentation of the fresh liqueur vinasse can be directly conducted, component process is reduced, and manpower, material resources, financial resources and time are saved; the period of entering the high temperature period is short (reaching 55 DEG C in one day, reaching 85 DEG C in three days), the period of maintaining high temperature fermentation time is long (maintaining 83-85 DEG C for three days), and the fermentation period is shortened (only 15-16 days) and 26-27 days shorter than that of existing liqueur vinasse decomposition agent; the yield and the quality (putrescibility) of organic fertilizer are effectively improved, secondary pollution decomposition and soil alkalinization of the vinasse are avoided, the environment and the soil are protected, and a new shortcut for making high quality organic fertilizer through direct high temperature compost maturity of the liqueur vinasse is opened up.

Description

technical field [0001] The invention relates to a distiller's grain decomposing agent, in particular to a distiller's grain decomposing agent and a preparation method and application thereof. Background technique [0002] Distiller's grains are the direct leftovers in the brewing process. At present, more than 50 million tons of distiller's grains need to be processed in my country. Therefore, people have been paying attention to the problem of disposing of distiller's grains after fermentation. Liquor distiller's grains are easily fermented and corrupted, and emit stench and easily pollute the environment. Because it contains a lot of crude fat, crude starch, crude protein and rich in nitrogen, phosphorus, potassium and polysaccharides, it is an excellent source of organic fertilizer. Therefore, the use of distiller's grains to make organic fertilizers can not only solve environmental problems, turn waste into treasure, but also provide high-quality organic fertilizers for...

[0007] Chinese patent CN 104909854 A discloses a Maotai-flavored distiller's lees decomposing agent strain, the decomposing agent is composed of Bacillus, yeast, actinomycetes and acetic acid bacteria, but does not specifically disclose the compounding ratio, The effective bacterial activity of its decomposing agent bacterial agent is ≥0.5×10 8 cfu / g

[0008] Although there are many high-temperature decomposing bacteria agents for distiller's grains disclosed above, they all need to be pretreated by reducing the alcohol content of the distiller's grains, reducing acidity, and adding auxiliary nutrients. Incomplete decomposition of distiller's grains leads to secondary pollution and corruption. At the same time, there are defects such as high addition of decomposing agent, low fermentation rate, long period of high-temperature composting, low degradation rate of organic matter, and incomplete decomposition. It is an urgent need for those skilled in the art to pre-treat distiller's grains and adjust components, and can directly inoculate liquor distiller's grains for high-temperature composting and rapid decomposing bacterial agents
