The external transport path 20 constitutes a transport path from the carry-out port 11 of each processing chamber 1 to the carry-in port 10. The external transport path 20 has a composting scraper 21 at a position that exits the carry-out port 11, and scrapes manure (hereinafter referred to as compost) that has been processed into the container A and is composted by the adjuster 22. After adjusting the water content and the like, the bag is packed in the bagging machine 23.

The bagging machine 23 also packs the above-mentioned dried larvae.

The empty containers from which the compost has been removed by the compost scraping machine 21 are sent to a container stock 24, where they are sequentially stacked and stocked, and if necessary, sent one by one for the next treatment.

Next to the container stock 24, a manure filling machine 25
There, the empty container is filled with a predetermined amount of manure to be processed. This manure filling machine 25 has a manure adjusting machine 2
According to 6, manure whose water content is adjusted is sent.

Next to the manure filling machine 25 is an inoculation machine 27,
Here, the housefly eggs are inoculated into the stool by a predetermined number according to the filling amount of the stool. In this way, the container A filled with the manure to be treated and inoculated with the housefly eggs is sent to the carry-in port 10 of the treatment chamber 1 and sequentially arranged on a predetermined shelf 5.

Next, a process of treating pig manure using the above-mentioned apparatus will be described. a. Preparation of raw materials If sawdust or straw is mixed in manure, the number of days required for composting will increase and the larva production will decrease (hatching rate will decrease). Therefore, it is preferable to use only manure, but it occurs from pig farms. Often, large amounts of sawdust and straw are mixed in the excrement,
It is adjusted to 70% (wt%) or less by adding manure not containing sawdust or straw or containing a small amount of these. Note that this adjustment may be performed by removing straw along with contaminants. Urine or water, or night soil and water are added to this and mixed with stirring to obtain a water content of 70 to 8
Adjust to 0%. b. Container filling 1234 mm x 770 mm rectangular flat plate-shaped dedicated container (bat) is filled with adjusted excrement so that the thickness is about 10 cm. c. The housefly eggs are planted in the manure filled in the inoculation container. The amount at that time is about 50 g of housefly eggs per 100 kg of adjusted manure, and it is evenly divided into several places from the surface of manure. d. Processing chamber conditions The processing chamber is maintained at a temperature of 20 to 30 ° C. and a humidity of 50 to 80%.

The above-mentioned raw material adjustment is carried out by the manure adjusting machine 26, which is filled in the container A by the manure filling machine 25, which is inoculated with the housefly egg by the inoculating machine 27, and the treatment room 1
Of the processing container loading and unloading device 6 and the conveyors constituting the respective shelves 5 to drive the conveyors and arrange them on the shelves 5 in the processing chamber 1 and allow them to stand still.

As a result, the eggs hatch, the larvae actively eat manure and compost it, and after 4 to 5 days, the grown housefly larvae crawl out of the container for pupation. The crawling larvae drop onto the larvae carry-out conveyor 12. This is carried out by the conveyor 12, subjected to insecticidal treatment, dried to a water content of about 10% and packed in a bag.

The treated compost-containing container A from which the larvae have crawled out is driven out of the carry-out port 11 by driving the conveyor and the processing-container carrying-in / carrying-out device 6 which constitute the shelf 5, and the compost-scraping machine 21. Then, the compost is scraped out, sent to the stock stock 24 for stocking, and sent to the manure / filling machine 25 one by one.

The compost scraped out by the compost scraping machine 21 is watered by the adjusting machine 22, stirred to adjust the water content, and then packed by the bagging machine 23.

The above-mentioned steps are carried out for each of the treatment chambers 1 arranged side by side, and in each treatment chamber 1, the first day is set to the uppermost stage according to the number of days until the larvae crawling out is completed after the inoculation of housefly eggs. , The next day, for example, the second stage, the delivery date of the manure to be treated is different for each stage, and the compost container with only the shelves corresponding to the treatment completion date is carried out and a new manure container is stored. It is preferable to sequentially treat livestock manure that occurs every day by a method such as carrying in, without setting an accumulation period, and set the volume and / or number of treatment chambers according to the amount of livestock manure produced.

In the above example, water content is adjusted by adding water to the treated compost, but it is dried to obtain a water content of 10%.
The degree may be set so that it can be stored.
