Abstract
The invention provides a method for converting kitchen waste and waste animal and plant into feed. The method is characterized by comprising the following steps of: selecting kitchen waste and waste animal, which are not severely rotten and deteriorated, as raw materials; hydrolyzing keratoprotein such as feather and the like by acid at high temperature; sterilizing and disinfecting the other raw materials; neutralizing by ammonium bicarbonate; and fermenting feed yeast to produce safe and high-efficiency feed. The waste can be recycled, the value can be greatly increased, the pollution problem caused by the kitchen waste and the urban and rural waste animal and plant can be solved, the obtained feed product is safe and efficient, and the quality of animal meet can be guaranteed. The method is simple in processing equipment, convenient to operate, and low in production cost, thereby being suitable for the modern industrialized production.
Description
Technical field
The present invention relates to a kind of changing rejected material to useful resource technology, particularly a kind of changing food waste and discarded animals and plants are converted into the method for feed.
Background technology
Leftover bits and pieces that changing food waste comprises leftovers that food and beverage enterprise, canteen and family kitchen produce, leftovers, rushing water water, trim vegetables for cooking etc.; Discarded animals and plants comprise fur, fish scale, the pluck that is produced when butchering the livestock and poultry fish, melon skin fruit stone, the substandard products leftover bits and pieces of agricultural product, crop stalk, weeds etc.Above-mentioned substance is usually done the garbage loading embeading processing more, has not only taken valuable land resource but also polluted environment, impurely goes up, underground water source and air; Make fertilizer then value is too low as treated; As do not sterilize or handle without strict sterilization and make feed and then can endanger food security and aquaculture safety, national laws and regulations never allow to do like this.
Summary of the invention
The objective of the invention is provides a kind of more valuable method of resource in order to solve above-mentioned technical problem for changing food waste reaches discarded vegeto-animal processing, and promptly changing food waste and discarded animals and plants are converted into the method for feed.
For realizing the foregoing invention purpose, the concrete processing method that the present invention adopts is following:
1. raw material is collected and preliminary treatment: collect serious not putrid and deteriorated changing food waste and discarded animals and plants; Wherein discarded plant and thicker raw material are smashed or chopped; Length is no more than 2 centimetres, and the raw material that feather, fish scale etc. is contained keratoprotein places agitated reactor, with smashing or the raw material of chopped and other raw material press filtration moisture content together; Filter residue is placed solid-state fermentation tank, and the degrease of will filtrating is placed in the liquid fermentation tank.
2. hydrolysis and sterilization: in agitated reactor, add 20～50% acid, and be warming up to 90～110 ℃, hydrolysis is 1～10 hour in strong acid, cutin albumen such as feather and fish scale all is hydrolyzed to the aqueous solution that contains amino acid, little peptide, peptone etc. in acid; Add in proportion in solid and the liquid fermentation tank containing acid hydrolysis liquid while hot then, and stir, make in solid and the liquid fermentation tank pH value,, make its pH value till below 2.0 like acidity suitable supplemental acid more inadequately below 2.0; Or add acid separately and stir to pH2.0, through sterilizing, deodorizing in 20～30 minutes and eliminate peculiar smell.
3. adjustment moisture content: in the solid-state fermentation tank of handling through above-mentioned sterilizing, add wheat bran, corn flour, the moisture content of adjustment solid-state fermentation tank raw material remains on 55～60%, stirs static processing 20～30 minutes.
4. neutralization: fully mix thoroughly in the solid, liquid fermentation tank of above-mentioned processing, adding carbonic hydroammonium or ammoniacal liquor or liquefied ammonia or alkali or carbonate, to pH value 5.0～6.0, neutralization acid and acid poisonous and harmful substance wherein.
5. fermentation
5.1 the selection of fermented bacterium: according to the good growth and breeding of ability in the culture medium of pH5.0～6.0; Can make full use of nonprotein nitrogen and carbohydrate synthesizing amino acid and bacterium protein in the culture medium, the coarse-fibred condition in the culture medium of significantly degrading is selected a kind of mixed bacteria of or a plurality of bacterial classifications.
5.2 the preliminary treatment of fermented bacterium: inoculate fully to soak in 1～2% glucose temperature boiling water that bacterial classification was added in preceding 1～2 hour 25～35 ℃ and be incubated subsequent usely, the consumption of bacterial classification is 1～2% of the raw mix dry that promptly neutralized of culture medium.
5.3 inoculation fermentation: the bacterial classification that preliminary treatment is good adds in the solid, liquid fermentation tank that has neutralized; And add 1% calcium monohydrogen phosphate or phosphate fertilizer; Add amount of urea make nonprotein nitrogen in the culture medium account for dry 1.5% or in, add an amount of phytase simultaneously and fully mix thoroughly, keep 25～30 ℃ of culture medium and fluid temperatures; Wherein the fermentation last stage keeps air humidity 90～95% in solid-state fermentation tank; Keep later on fermentation tank air humidity 70～80%, impel mycelia by media surface to the culture medium growth inside, ferment and finished in 1～2 day to ferment; Zymotic fluid in the liquid fermentation tank through filter press elimination moisture content, is changed over to filter residue in the solid-state fermentation tank and to carry out with the unification of solid fermentation thing that vacuum is drained or become the yeast feed product through oven dry, crushing packing.
The present invention utilizes changing food waste and discarded animals and plants to make raw material owing to the above process of employing, uses acid at high temperature also to use acid to other raw material sterilizing, carbonic hydroammonium neutralization, the safe and efficient feed of yeast for animal feeds bacterium fermenting and producing to the cutin proteolysis; Realize utilization of waste as resource, and significantly increment, the pollution problem of changing food waste and discarded animals and plants solved simultaneously to environment; In the processing procedure, oneself uses acid also to use acid to the thorough sterilizing of other raw material to feather isogonism proteolysis as amino acid, little peptide, peptone before fermenting, and the gained feed product is safe and reliable; Digestive utilization ratio is high, and yeast can produce benefit materials such as a large amount of B family vitamins and protease, cellulase in the growth and breeding process, can make full use of nonprotein nitrogen and carbohydrate synthesizing amino acid and mycoprotein in the culture medium; Improve 8～12 percentage points of the content of true protein in the culture medium, the content of crude protein improves 30～80%, and the crude fibre in the culture medium of can degrading significantly; Improve its digestive utilization ratio, oozy digestive ferment all digests reorganization with digestible substance in the culture medium, and other poisonous and harmful substance also is reassembled as useful and harmless material; Eliminated the harm of poisonous and harmful substance, feather isogonism proteolysis is an amino acid etc., can improve ferment effect and fermenting speed and improve amino acid whose structure and unbalance condition; Product after the fermentation has special yeast fragrance; Improved the palatability of product, guaranteed the animal flesh quality, contained sulfate is one of long necessary nutriment of livestock and poultry sashimi (raw fish) in the fermented product; As long as the content of sulfate in the animal feed is controlled in 3%; Just can not produce side effect such as have loose bowels, treatment facility is simple, and is easy to operate; With low cost, be fit to modernized factory and produce.
