Abstract

The invention discloses a bagasse fermentation method. The method comprises the steps of 1 yeast seed preparation, wherein 65%-70% of wheat bran and 25%-30% of rice bran are put into a vessel with the capacity being 18-20 liters; 2 starter making, wherein bagasse is put into a vessel with the capacity being 72-80 liters, 22-25 liters of distillers' products at the temperature of 30-40 DEG C is mixed in the vessel, 0.5-0.8 liter of above mentioned second seeds is inoculated, and the pH is controlled to be 3.5-5.5. According to the bagasse fermentation method, mixed bacteria composed of cellulose-decomposing bacteria, ammonium nitrate synthetic bacteria, starch amylomyces, protein decomposing bacteria and penicillium capable of producing ligninase is used for fermenting bagasse, and feed which is easy to digest and high in protein content can be prepared, wherein the content of crude protein is 15%, the content of crude fat is 10%, and crude fiber is reduced by about 20%. The bagasse is fermented and prepared to obtain cattle and sheep feed, processing and making methods are simple, the cost is low, the cattle and sheep feed obtained through preparation after fermentation is comprehensive in nutrition, has a sweet taste and improves the appetite of cattle and sheep, and the cattle and sheep love to eat and grow fast.

Description

A kind of method of bagasse fermentation

Technical field

The present invention relates to a kind of plant granulated slag optimized treatment method, the method for especially a kind of bagasse fermentation.

Background technology

Guangxi Zhuang Autonomous Region is that China first produces the big province of sugar, and its sugarcane acreage reaches more than 13,000,000 mu, sugarcane top Being about 15,600,000 tons, bagasse is 3,120,000 tons, and resource is very abundant, and yield is considerable, and bagasse and cane molasses are sucrose The byproduct producing, its crude fiber content is up to 30-50%, protein 2-8%, sugar 0.8%, and coarse ash, more than 6%, has Having a feature that source is wide, quantity is big and price is low, the energy of more than half being accumulated containing photosynthesis of plant, as non-competing The feed resource of striving property, as long as rational Processing farage can be carried out, improves the intake of its digestible energy, is particularly used for feeding The ruminant domestic animal such as ox, sheep, remains able to become high-quality feed source.Bagasse contains lignin, and it is a kind of than sugar, pectin, fiber The membranaceous material that also difficulty is decomposed such as element, even if ruminant is also difficult to digest, is therefore not typically used as feed.It was found that it is wooden Element often increases by 1%, and digestibility reduces by 5%.When bagasse moisture is 10.3%, content of lignin is about 20%, and digestibility is very Low.

And sugar refinery byproduct is made to the developmental research aspect of feed, conventional research processing method has：1st, chemical treatment Method；As：By fresh cane slag with after caustic soda process, add blackstrap to make and store 1 year without rotten ox feed；2nd, thing Reason facture, as being placed in sugarcane in intermittent reaction pot, under conditions of 180 DEG C, steam processes 7-10 minute, turning of its sucrose Rate brings up to 60% from 15%.3rd, biological treatment, as with multivitamin symbiotic fermentation bagasse, made cellulose reduce 60%, thick protein and crude fat are multiplied several times, in order to ox of breast-feeding, day milk yield can improve more than 30%.Use bagasse As feeding cattle and sheep feed, have studied decades at present.But also do not find the fine side being suitable for cooking bagasse feed Method, and it is now recognized that cattle and sheep directly fed by bagasse is not all right, nutritional labeling very little, causes utilizing bagasse all the time It is as fuel or paper making raw material, cause a large amount of wastes of resource.

Content of the invention

It is an object of the invention to provide the method for a kind of bagasse fermentation.

The method of this bagasse fermentation comprises the steps of：

1. the sort of quyi：Being in the container that 18-20 rises at capacity, putting into 65-70% wheat bran, 25-30% rice bran, adding temperature is The water of 35-37 DEG C, keeps material moisture at 65-70%, inoculates above-mentioned Mixed Microbes 18-20 gram, train 12-14 hour, bud to be fermented Savory, it is used as secondary seed；

2. koji：Then bagasse being put into capacity is in the container that 72-80 rises, and is doped into the distiller's spent grains 22-25 of 30～40 DEG C Rising, inoculating above-mentioned secondary seed 0.5-0.8 liter, pH controls 3.5～5.5；Cultivate 24-26 hour at 30～45 DEG C, generate With the various enzymes based on cellulase, lignoenzyme, can decompose and softening fibre element, hemicellulose, pentosan, moreover it is possible to increase egg White matter content；Then add blackstrap, brewex's grains, alcohol grain, as required, squeezing again, be dried, make feed；

3. store and feed：After koji terminates, drying granulated slag or drying, sealed type storage is standby；Directly feed domestic animal；

Above percentage refers both to percentage by weight.

If the fermentate adding fecula with fermentation bagasse feeds ox, the digestibility of various compositions is all improved, wherein slightly Digestibility of fiber reaches 70-75%, improves 45% than general untreated crude fiber digestibility；Its raw material weight component is as follows：Mixed Close bacterium 1-15 part, bagasse 72-74 part, fecula 10-12 part, distiller's spent grains 12-15 part.

The beneficial effect of the invention：

The present invention uses and contains cellulose-decomposing bacteria, ammonium nitrate synthesis bacterium, starch saccharification bacterium, protein decomposing dacteria and can produce The Mixed Microbes that the Penicillium bacterium of lignoenzyme is constituted, ferment bagasse, can make crude protein content be the 15%th, crude fat 10% and The high feed of the easy digestion of crude fibre minimizing about 20%, protein content.Bagasse prepares cattle and sheep feed by fermentation, Processing method is simple, low cost, and the cattle and sheep feed nutrition preparing after fermentation is comprehensive, have fragrant and sweet taste, improve cattle and sheep Appetite, cattle and sheep like to eat, and growth is fast.
