Organic Fertilizer Manufacturing System

Abstract

The present invention provides a system for reducing manual work and efficiently manufacturing organic fertilizer substrates in the process of treating livestock manure by housefly larvae. A kind of organic fertilizer manufacturing system of the present invention is to utilize housefly larvae to manufacture organic fertilizer from the excrement of domestic animals, is provided with the 1st cultivation processing storage part that cultivates the larva hatched from the egg, in the 1st cultivation processing storage part The second cultivation processing storage part divided into multiple sections is arranged below the bottom of the bottom, and the falling part that utilizes the larvae to crawl out and fall is set, and the larvae are dropped from the dropping part to the second cultivation processing storage part of the next stage, and the process is repeated. This treatment is performed multiple times, and each cultivation treatment storage unit produces an organic fertilizer base material by enzymatically decomposing excrement in the larvae and excreting it during the rearing process of the larvae, and has a mechanism for accumulating and discharging the produced organic fertilizer base material. The organic fertilizer base material accumulation unit and the larva accumulation unit that accumulates and discharges the larva clusters that finally climbed out and fell from the cultivation treatment storage unit send out the organic fertilizer base material and the larvae clusters.

Description

technical field [0001] The present invention relates to an organic fertilizer production system and method for producing organic fertilizer from excrement of livestock by using housefly larvae. Background technique [0002] In general, in livestock facilities such as pig breeding and dairy cow breeding, excrement and urine are discharged according to the number of cows raised per day, and the treatment is generally a composting method using microorganisms. [0003] However, the water content of livestock excrement is high, so the treatment with microorganisms is too time-consuming. In some areas, a large amount of livestock manure produced cannot even be processed and piled up in the open air. It becomes a source of groundwater pollution and causes social problems. a big problem. In particular, environmental standards have become stricter recently, and it is not allowed to easily discard foul-smelling and unhygienic livestock manure. [0004] With the expansion of the scal...

Problems solved by technology

[0007] However, although the insect biological treatment system disclosed in Patent Document 1 eliminates or reduces the hazards of these livestock manures by making the housefly larvae eat them, the organic fertilizer treatment using the housefly larvae is harmful to the The waste in the container is inoculated with housefly eggs and stored in a treatment room where the temperature and humidity can be adjusted. The eggs are hatched and the larvae are reproduced. Carrying in and sending out is all done by hand. In addition, the larvae have the ability to crawl if they grow beyond a certain level. To take advantage of the habit of emerging from the medium and becoming pupae, the larvae climbing out of the container must also be handled manually

Moreover, there are the following problems: in the treatment room where these operations are performed, the smell of feces and urine is full, and the larvae (maggots) crawling out are crawling everywhere, etc., the working environment is obviously poor, and it is not suitable for manual work by personnel.

[0008] In addition, if the housefly larvae have enough breeding volume and bait within 1 week, the processing amount of the bait, that is, the feed will increase dramatically. On the contrary, if the corresponding breeding area or bait is not provided, the following problems will also occur : The organic fertilizer base material produced by enzymatically decomposing and excreting livestock feces in the larvae is reduced, and the reproduction of larvae is also slowed down
