ELECTRICAL HEATING :
Air inside the Tray dryer will be heated by "U" tube air heaters each of 1000 watts. The heaters are fitted on the sides of the dryer to facilitate uniform heating.

Maximum temperature attained inside the dryer will be 100/200/300 'c and will be indicated by a dial thermometer fitted on the dryer.
Temperature inside the dryer will be contorolled by a thermostat over full range of heating load. Total heating load for will be:

MODEL	100°C	200°C	300°C
BO-12	3 K.W.	6 K.W.	9 K.W
BO-24	6 K.W.	9K.W.	12 K.W.
BO-48	9 K.W.	15K.W.	18 K.W.
BO-96	15 K.W.	21 K.W.	27 K.W.
BO-192	36 K.W.	72 K.W.	105 K.W.

STEAM HEATING:
Air inside the dryer will be heated by two steam caloriefier made out of mild steel pipes and tubes and suitably grooved by high conductive continous galvanised fins. there will be two steam coils fitted diagonally opposite each to facilitate uniform and faster heating. Maximum temperature attained inside the dryer will be 100'c and will be indicated by a dial thermometer fitted on the dryer.

THERE ARE 2 STEAM COILS IN ALL MODELS HOWEVER THEIR SIZES AND HEAT TRANSFER AREAS ARE DIFFERENT IN ALL MODELS
