the features of Photochemical reactor

Photochemical reactor is relatively old, inside the heated plate divided into several layers. Heating plate was passed through hot water or low pressure steam as the heating medium, the spread of drugs to be dried on a hot plate tray, close the door, inside the evacuated using a vacuum pump. Heating plate in the heating medium circulating in the drug is heated to a specified temperature, the water began to evaporate and gradually pumped with vacuum. This device is easy to control, condensate recovery solvent is evaporated, the drying process can not easily be contaminated drugs can be used in Laboratory reactors , sterilizing the packaging material and heat treatment. In the 1980s API industry multi-use this device as the main dryer, but not easy to reel line cleaning and

sterilization line, slow drying, high labor intensity, but also to achieve uniformity of the drug, even after drying after mixing apparatus for mixing powder, bulk drugs now on the large-scale production has been rarely used, used in small scale production or packaging materials heat treatment.
