Under circumstances where thermal degradation of a product is possible, it can usually be minimized by adopting a higher temperature range, as the shorter exposure times generally result in a lower partial degradation. Still, it can be applied to both moisture-sensitive and moisture-resistant products, for which dry (160180C) and moist (121134C) heat sterilization procedures are respectively used. The instruments and glassware to be sterilized are kept in a tray are then passed through the tunnel on a conveyer belt, moving at a controlled speed. Large scale membrane filtration is a very expensive process. In the case of flaming, the instrument is dipped in alcohol or spirit before burning it in a gas flame. Process Simulations (20) 1.
