Development of a Prototype Dry Heat Sterilizer for Pharmaceuticals Industry

The use of sterilizer in pharmaceutical industries are very important due to having capabilities of reducing microbial contamination of medicinal preparations. Sterilizer eliminates all form of microorganisms and other biological agents, which helps to maintain a sterile environment. Although several researches conducted research on design & implementation of sterilizer, due to lack of accuracy, safety issues, operational limitation and high cost, these sterilizers are not suitable for pharmaceutical industries in Bangladesh. In this project, a low-cost and user friendly Dry Heat Sterilizer (DHS) is designed and implemented for pharmaceutical industries. In order to make fully automated control scheme, Programmable Logic Controller (PLC) and Human Machine Interface (HMI) is used in this experimental work, which ensures necessary safety measures also. The performance of the implemented DHS is analyzed for two different experimental setups. It is found that the DHS made from locally available materials can perform satisfactory and can be used in pharmaceutical industries as well as for oven applications.
