Working Process
Heat depend on different product the temperature should be different.
Normally the best temperature is 55-56, if the product can not bear high temperature, you should longer the time or the concentration of EO
Keep heat
Vacuum in order to reduce the mix air, EO is easy to fire
Keeping Vacuum it is also for a test about the seal of equipment
Humidify vacuum will also loose water in air, so this is a compensation 60_+15HR%
EO we show you how to operate with one product
Sterilization normally 6-8hours, more adsorption longer time
Clean
