Development of Environmentally safe heat pump dryer for biological applications.

Development of Environmentally safe heat pump dryer for biological applications.

The main aim of this proposed project is to design and develop a compact efficient environmentally safe heat pump dryer. Special features of proposed design are (i) simultaneous  control  of  bypass  air  and  dryer  inlet condition to get maximum coefficient of performance (COP) and drying rate, (ii) use of zero ODP and  low GWP  refrigerant,  which  is  environmentally  safe,  (iii) compact  dryer  design  and  (iv)  design  based  on  the wider   variation   of   climatic   condition   (ambient temperature and humidity).

Proper control strategy will be developed  for  optimum operation  in  both dry and moist weathers.

As the air inlet condition of the dryer can  be  easily  controlled,  this  dryer  can  be  effective used for bio and pharmacitical products.
