Industrialized processing method of silkworm excrement for feed

Abstract

The invention discloses an industrialized processing method of silkworm excrement for a feed. The industrialized processing method comprises the steps of centrally purchasing, storing at a constant humidity, screening to remove dust, drying, separating by wind, collecting, screening, and drying at a low temperature, thus obtaining qualified silkworm excrement. According to the method, the un-aired silkworm excrement collected by farmers can be directly treated without being subjected to any pretreatment by the farmers, and can processed and produced by enterprises as long as being collected. The silkworm excrement processed by adopting the processing method is uniform in particles and less in impurities, and can be used for extracting silkworm excrement with different particle sizes by stages for production and use of other products.

Description

technical field [0001] The invention relates to the field of industrial processing of silkworm excrement used in agriculture for feeding livestock, in particular to an industrial processing method of silkworm excrement for feed. Background technique [0002] Dried silkworm excrement is in short cylindrical shape, 2-5mm long and 1.5-3mm in diameter. The surface is gray and rough, with 6 obvious longitudinal ribs and 3-4 horizontal shallow lines, both ends are slightly flat, hexagonal, hard and brittle, easy to shatter when wet, slightly grassy, ​​with Dry, black, solid, uniform, and free of impurities are preferred. They are mainly produced in Zhejiang, Sichuan, Henan, Jiangsu, Hunan, Yunnan, Guangdong, Anhui, Gansu, Hubei, Shandong, Liaoning and other places. Silkworm moth larvae are produced every year.

Problems solved by technology

The surface is gray and rough, with 6 obvious longitudinal ribs and 3-4 horizontal shallow lines, both ends are slightly flat, hexagonal, hard and brittle, easy to shatter when wet, slightly grassy, ​​with Dry, black, solid, uniform, and free of impurities are preferred. They are mainly produced in Zhejiang, Sichuan, Henan, Jiangsu, Hunan, Yunnan, Guangdong, Anhui, Gansu, Hubei, Shandong, Liaoning and other places. Silkworm moth larvae are produced every year. Sand is more, and it is mostly used as fertilizer in the prior art, because the sale requirement of silkworm excrement in the prior art is more, the most notable requirement is to require that silkworm excrement is carried out to the air for a long time, guarantees that its moisture content is at 13 Generally, silkworm excrement manufacturers with high moisture content hardly purchase them. At the same time, due to the low purchase price, many farmers are unwilling to waste too much time on this. At the same time, the arrival of rainy days often directly leads to the loss of all silkworm excrement. Therefore, Farmers often prefer to use it directly as waste rather than sell it to manufacturers after drying. Silkworm excrement has a good feeding effect when used as a supplementary material for feed. At the same time, the nutrients contained in silkworm excrement are also relatively balanced. It can be directly mixed with full-price feed and fed to livestock after deep processing in feed factories. The lowest can replace 5% of the total ration, and the highest can reach more than 20%, which greatly saves the cost of breeding, but Difficult acquisition and processing of silkworm excrement is a big problem
