蚕茧生产带有季节性,在短时间内收获的大量生茧,缫丝厂不可能在短时间内处理完毕,必须进行贮藏以便做到全年均衡生产。过去,大多用热风干燥的方法进行杀蛹、干燥处理,但由于生茧容易生蛾,必须在短时间内处理大量生茧。为此需要大规模的设备投资以及临时性的大量劳力,否则就容易造成生茧长蛆、长蛾和发霉。生茧经过100—140℃的高温热空气干燥后,茧蛹虽然 Cocoon production with a seasonal, in a short period of time to harvest a large number of raw cocoon, reeling plant can not be completed in a short time, must be stored in order to achieve balanced production throughout the year. In the past, most of the methods of drying with hot air are used to kill pupae and dry them. However, since raw cocoon is easy to produce moths, a large amount of raw cocoon must be handled in a short time. This requires large-scale investment in equipment and a large amount of temporary labor, otherwise it is easy to cause long cocoon maggot, moth and moldy. After the cocoon after 100-140 ℃ high temperature hot air drying, pupa though
