Embodiment 1

[0018] Step 1: Separating the paper, chopsticks, toothpicks and plastics from the food waste, filtering, crushing and drying, so that the particle size is 30 mesh and the organic dry matter content is ≧50%;

[0019] Step 2: Add 15% soybean flour and 20% rice bran to the pretreated kitchen waste in Step 1, stir evenly, and sterilize with high pressure steam at 121°C for 20 minutes to obtain a fermentation substrate;

[0020] Step 3: At 28°C, inoculate 2 parts of Bifidobacterium, 6 parts of Lactobacillus, 3 parts of Bifidobacterium and 5 parts of yeast in a liquid medium with a pH of 6.2, and inoculate 10 m 3 The flow rate of / h is passed into sterile air, and after 2 days of expansion, it is concentrated and purified to obtain a composite bacterial agent. Under the nitrogen-filled condition of 28°C, after mixing 10% of the composite bacterial agent in the fermentation substrate of step 2, Every 3h, stir 20min with the speed of 60r / min, after fermenting 20h, make crude feed;

Abstract

The invention discloses a method of producing pig feed with kitchen waste. The method comprises the following steps of: step I: separating, filtering, grinding and drying the kitchen waste, step II: mixing and sterilizing a raw material, step III: adding 10-15% of complex inoculant into the raw material under a nitrogen condition at 28-36 DEG C, performing intermittent stirring and fermentation for 20-36h to form roughage, and step IV: mixing 0.6-1.0% of monocalcium phosphate and 0.1-0.2% of Chinese herbal medicine antibiotic into the roughage for granulation to form the pig feed. The Chineseherbal medicine antibiotic comprises the following ingredients in parts by weight: 20-30 parts of berberine hemisulfate salt, 12-16 parts of allicin, 18-24 parts of aloe-emodin, 15-19 parts of sodiumhouttuyfonate and 0.05-0.09 parts of propylgallate. The method can efficiently utilize the kitchen waste; the produced pig feed is strong in stability and has low deterioration possibility; and Chinese herbal medicine ingredients in the feed can obviously improve appetite, immunity and disease resistance of a pig, further increases a survival rate and a yield of the pig and improves pig meat quality.

Description

technical field [0001] The invention belongs to the technical field of turning food waste into feed, and in particular relates to a method for producing pig feed by using food waste. Background technique [0002] According to relevant data, the incidence of pigs fed directly with kitchen waste is 30-50% higher than that of pigs raised normally. Salmonella, Escherichia coli, Staphylococcus aureus, Mycobacterium tuberculosis and Zhi More than 10 kinds of pathogens, such as Shigella, can easily cause zoonotic diseases. The patent application number is CN201510714605.1, which uses microbial starter to ferment the mixed raw materials such as kitchen waste clinker, rice bran powder and corn flour to produce insect feed. The feed can improve product quality, but the feed is easy to spoil and deteriorate. Accumulate large amounts of toxins. The pig feed produced by the invention has strong anti-corruption performance and anti-oxidation ability, has high safety, can obviously reduc...
