Abstract

A method for producing animal feed by using chicken manure includes the following steps: oven-drying chicken manure at 80-300 deg.C, making its water content be up to 18-40%, the pulverizing to 4-20 meshes, placing the pulverized chicken manure in fermentation tank to make fermentation by adding mixed inoculum at normal temp., then screening, low-temp. drying, and packaging the finished product. Said invented method repeatedly treat chicken manure, so that the harmful substances and odour in the chicken manure can be effectively removed, and the protein content can be raised. Said method is simple, can effectively resolve the problem of chicken manure treatment, and can raise its additional value.

Description

Utilize the method for chicken manure braking thing feed

Invention relates to a kind of method of utilizing fowl and animal excrement braking thing feed, particularly utilizes the method for chicken manure braking thing feed.

At present, the most frequently used processing method of fowl and animal excrement is to use as the farmland organic fertilizer behind the heap fermentation, but along with development extensive, the industrialization animal husbandry, the fowl and animal excrement amount is big and concentrated, the required place of processing method commonly used is big, environmental pollution is serious, and the feed protein that can reuse is in a large number run off.Fowl and animal excrement is the tall and big 70-80% of indigested feed in the chicken manure particularly, and the protein content in the dried poultrymanure is 25-30%, is equivalent to 75% of three grades of fish meal protein matter content.How solving the integrated treatment problem of fowl and animal excrement, make it produce high economic benefit, is the target that at present a lot of people pursue.The patent application (number of patent application: 91101426.8, notification number: 1064595) of " manure of livestock and poultry producing protein matter feed making method and equipment thereof " as the Decree of Patent Office of China on September 23rd, 1992, it discloses pours the rotor heating type into after a kind of bacterial classification that utilizes wet chicken manure to add appropriate amount of auxiliary materials and choose in advance stirs and carries out fermentation process in the fermentation machine fast, is that the material extruding slivering post of cream pasty state is strong to carry out the regeneration animal feed that dewatered drying one-tenth can directly feed or store after then will be by fermentation.Though this method has solved the handling problem of fowl and animal excrement,, the processing cost height, problem such as should not promote because the equipment that adopts is special equipment.

The purpose of this invention is to provide a kind of method of oven dry, fermentation that adopts handles chicken manure and utilizes chicken manure to brake the method for thing feed.

The objective of the invention is to be achieved through the following technical solutions:

A kind of method of utilizing chicken manure braking thing feed, comprise pulverizing, fermentation, it is characterized in that making its water content reach 18-40% the chicken manure oven dry earlier, bake out temperature is: 80-300 ℃, after being crushed to the 4-12 order then, compound chicken manure packed into get involved bacterial classification in the fermentation vat and ferment, ferment laggard row filter, low temperature drying, finished product packing.

Characteristics of the present invention are: 1. through fermentation process repeatedly, can effectively remove harmful substance and stink in the chicken manure, improve Protein content, and recycling; 2. processing method is simple, and equipment investment is few, is fit to very much produce in batches; 3. can effectively solve the handling problem of chicken manure, improve its economic value added.4. can solve the problem that present people, fowl poultry strives grain.

Technical scheme of the present invention is explanation in detail in conjunction with the embodiments.

Earlier chicken manure is dried under the temperature about 200 ℃, its water content is reached about 30%, after then it being crushed to about 10 orders, the vinasse of adding chicken manure weight 10% or wheat bran or vinasse, wheat bran respectively add 5% and mix, mixed chicken manure is packed in the fermentation vat, get involved mixed bacteria simultaneously and carry out normal temperature fermentation.The mixed bacteria of getting involved is: the hyphomycetic mixed bacteria of lactic acid bacteria, saccharomycete, photosynthetic bacteria, fermentation system.Fermentation is carried out at twice; Get involved for the first time the mixed bacteria sealing and fermenting about 20 hours after, get involved mixed bacteria once more and carry out fermenting second time; For the second time sealing and fermenting about 12 hours after, just can thoroughly remove the excrement stink, the harmful substance in the chicken manure of degrading activates its nutrition.After fermentation is finished, screen, with the material after the screening under the temperature about 70 ℃ through the row low temperature drying, the material after the oven dry through row packing, is just become the animal feed finished product.

The animal feed that the present invention produced adds about 10% in the feed of raise poultry, can effectively suppress the disease and pest in the poultry stomach, the generation of the various diseases of prevention animal.

Claims

1. method of utilizing chicken manure braking thing feed, comprise pulverizing, fermentation, it is characterized in that earlier chicken manure being dried down at 80-300 ℃, make its water content reach 18-40%, after being crushed to the 4-20 order then, can mix through row with vinasse or wheat bran, will mix chicken manure and pack that the intervention mixed bacteria ferments in the fermentation vat into, ferment laggard row filter, low temperature drying, finished product packing.

2. a kind of method of utilizing chicken manure braking thing feed according to claim 1 is characterized in that mixing consisting of of chicken manure: chicken manure 80-100%, vinasse 0-15%, wheat bran 0-16%.

3. a kind of method of utilizing chicken manure braking thing feed according to claim 1 is characterized in that the mixed bacteria of getting involved is: the der Pilz mixed bacteria of lactic acid bacteria, saccharomycete, photosynthetic bacteria, fermentation system.

4. a kind of method of utilizing chicken manure braking thing feed according to claim 1 can be divided into for two steps when it is characterized in that fermenting; The first step: will mix chicken manure pack into get involved mixed bacteria in the fermentation vat after, with the fermentation vat sealing, fermented 18-28 hour; Second step: after 18-28 hour, get involved mixed bacteria in first step fermentation for the second time, fermentation 10-16 hour is continued in the sealing back.

5. a kind of method of utilizing chicken manure braking thing feed according to claim 1, the temperature that it is characterized in that low temperature drying is 34-80 ℃.
