| description | Milk is a good medium for microbial growth because it has a high moisture
content and complex nutrients . This causds the milk degrade asily and has a
short storability. Modifying the milk into powder using spray dryer equipment
could increase the storability of the milk. Spray dryer conventional that found in
society is an industrial-scale with high capacity and has a very expensive price.
This condition required to design a cheap spray dryer with a medium capacity
tobe used widely in the community. The purpose of this research is to design spray
dryer with pneumatic nozzle type for drying milk.
The material that is used is a cow milk which have been pasteurized and
homogenized. Obtaining the optimum drying conditions is did by analyzing the
influence of the inlet air temperature and drying airflow on the quality of the final
moisture content , bulk density , degree of whiteness , wettability and flowability
powders. It also did by analyzing the influence of the inlet air temperature and
drying airflow on the production efficiency and air heating efficiency and drying
efficiency as an indicator of a good spray dryer . Inlet air temperature variation
used was 250

/s.
The result is an increasing of inlet air temperature causes a decreasing in
the moisture content , bulk density and production efficiency . The increasing of
air flow causes an increasing in moisture content , bulk density and production
efficiency . The optimal air temperature is obtained at 260
o
C and drying airflow
at 0.0066 m
3
/s based on the value of final moisture content and degree of powder
whiteness. The maximum of air heating efficiency was obtained at 94% and
maximum drying efficiency at 4,399%. |
