（一）烘茧设备：有柴灶、煤灶、机灶等，根据热的传递不同又可分为直接热灶和间接热灶两种。主要类型除部分土灶外有以下3种：（1）铝管风扇车子灶：（2）墙弄散热风扇车子灶：（3）墙弄散热无风扇车子灶。这里采用的是柴煤两用的间接热灶烘茧设备。
（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。 展开

(a) cocoon baking equipment: have ChaiZao, coal stove, machine, according to the hot stove etc transmission can be divided into different direct and indirect heating stove hot stove. Main type except some stoves outside have the following 3 kinds of: (1) aluminum tube fan car (2) make kitchen wall cooling fan (3) car kitchen wall cooling fan out without cars. Here is the wood and coal by indirect heating stove the cocoon equipment.
(2) the cocoon purpose: high, killing and maggot silkworm cocoon son to the proper baking, avoid to store water supply, mouldy mill perennial production. At the same time, can make the proper outer wearing characteristics, in order to improve the degeneration of silk studs.
(3) the cocoon requirements: high-quality, low consumption, safe, fast. To prevent steam temperature is appropriate, mildew, and achieves the cocoon is reasonable, the platoon is wet, prevent partial evenness fitness and old.
(4) : have the cocoon of dry (a drying) and dry (or three), the general method of drying with secondary drying dry cocoons.
Straight into the kitchen, fresh and dry cocoon baking time into dry cocoons. This hot economy, in the province. But because do not turn the cocoon, caused by dry heat unevenness, influence of cocoon quality, so less.
Secondary drying: fresh cocoon baking oven into six into a dry or kitchen head (i.e., baked rate) about 60% ~ 65%, also called semi-dry cocoons. Semi-dry cocoon certain time, the stove piled up 3 ~ 4 days, with the appropriate also sex after baking oven and optimum dry (i.e., fitness) cocoon baking rate for dry 38% to 43 per cent. This equipment utilization, dry degree, but easy injury cocoon shell.
