取一般的小型电动鼓风机略作改装,便可制成一台简易食用菌超净台。由于它功率大,风量足,故效果极佳,接种成功率与市售超净台不相上下。现将其制作和使用方法介绍如下: 1 制作技术 ①制作漏斗过滤器,用白铁皮焊制成一漏斗,漏斗颈直径3～4cm,与漏斗口直径比为1∶10左右,漏斗管长8～10cm,在管端和漏斗颈部各横装一层空气过滤网,用以过滤净化空气。②制作通风管,用白铁皮焊制一段铁皮管,管径一端与漏斗管径略大1mm,另一端略小于鼓风机出风口径1mm,管长视需要而定。 2 使用方法 使用时,将鼓风机、通风管、漏斗过滤器依序连接起来,接通鼓风机的电源,漏斗口处即为无菌区。将酒精灯放在手旁的无风区,即可按常规方法进行操作接种。 Take the general small electric blower slightly modified, can be made of a simple edible fungi clean bench. Because of its power, air volume enough, so the effect is excellent, the success rate of vaccination and commercially available ultra-clean bench comparable. Now the production and use of the method are described as follows: 1 production technology ① making funnel filter, made of white metal welding a funnel, funnel neck diameter of 3 ~ 4cm, and funnel mouth diameter ratio of about 1:10, Funnel tube length 8 ~ 10cm, in the tube end and the funnel neck each layer with a layer of air filter to purify the air filter. ② production of ventilation pipe, a tin tube with white metal welding, pipe diameter and funnel diameter slightly larger end of 1mm, slightly smaller than the other end of the blower outlet diameter 1mm, tube length as needed. 2 Use When used, the blower, ventilation tube, funnel filter in order to connect up the blower power, funnel mouth at the sterile area. The alcohol lamp in the hands of the windless area, you can operate according to conventional methods of vaccination.
