用塑料袋制作菌种,在高压锅内灭菌出锅时常发现有膨胀的料袋。这是由于高压灭菌时袋内空气被加热,当达到1.5个压安全阀开始自动排气,袋内外压力突然短时失衡,袋内空气膨胀而使塑料袋局部膨胀。胀袋后极易招致杂菌污染和破损。特别是在制作黑木耳菌袋时,料与袋膜分离不利划口出耳。笔者在多年的科研与生产中摸索出一个解决胀袋的好办法:首先在装料时不可装的过松或太紧、太满,要在料面以上留8～10cm空袋。然后不封口装入锅内,在最上层用报纸或麻袋盖好即可灭菌。灭菌结束待压力回到零时趁热在锅内将袋口扎紧后取出,再用事先备好洁净的皮筋固
With the production of bacteria in plastic bags, pots often found in the autoclave sterilization expansion bags. This is due to the autoclave when the air inside the bag is heated, when reached 1.5 pressure relief valve began to automatically exhaust, the pressure inside and outside the bag suddenly short-term imbalance, the expansion of the bag of air and plastic bags partially expanded. After the bag can easily lead to bacterial contamination and damage. Especially in the production of black fungus bag, material and bag film unfavorable separation unscrupulous ears. The author in many years of research and production to explore a good way to solve the bag expansion: First of all, when loading can not be installed too loose or too tight, too full, to leave the blank in the material above 8 ~ 10cm empty bag. And then not sealed into the pot, in the top layer of newspapers or sacks can be sterilized. End of sterilization to be back to zero when the pressure is hot in the pan tighten the bag after taking out, and then prepared in advance clean skin rubber
