(二)烘茧目的:高温杀死蚕蛹和蛆蝇,烘去茧子中的适量水分,避免霉变以便贮藏,供应丝厂常年生产。同时,可使外层丝胶适当变性,以提高生丝的净度。
(三)烘茧要求:优质、低耗、安全、快速。要防止蒸热霉变,做到温度适当,排湿合理,烘茧适干均匀,防止偏老、偏嫩。
(四)烘茧方法:有直干法(一次干燥法)和分干法(二次或三次干燥法),一般多采用二次干燥法干燥蚕茧。
直干法,鲜茧进灶一次烘成干茧。此法用热经济、省工。但由于不翻茧,受热不匀造成干燥不匀,对茧质有影响,因此少用。
二次干燥法:鲜茧进灶烘至六成干左右出灶(即头冲),此时烘率约60%~65%,亦称半干茧。半干茧出灶堆放一定时间,约3~4天,待其适当还性后再进灶烘至适干(即二冲),此时适干茧烘率约为38%~43%。此法设备利用率高,干燥程度均匀,但易伤茧层。
