Spray
drying is the preferred method of producing instant powder from liquids. Spray
dryer manufacturers in India offer a variety of spray drying equipments
featuring nozzle atomization or disc atomization. Some dryers may feature both
designs for fast production cycles and refinements include non-stick drying
chambers. Fluid is fed into a heated chamber through high pressure nozzles and
air at high pressure is mixed with the fluid to achieve atomization. Heating
may be through thermic fluid air heater or steam radiator using oil or gas.
Additional features include re-circulation system to provide fine powder.
Spray dryer manufacturers in India custom design and build drying equipment according
to physical and chemical properties of the product, initial and final moisture
content, temperature and drying characteristics and the production capacity
required. Additional considerations are flammability and toxicity of the
product where special care is required. Spray dryers may then incorporate a
drying chamber filled with inert gas or special filters or both.
One
critical process is atomization. Nozzles produce coarse particles whereas
rotary disc atomizers produce fine grain powders. The other important process
is hot air mixing, determined by the product to be dried and method of delivery
of hot air under pressure through the distributor. When you pick specialist
spray dryer manufacturer in India, you can be sure all these parameters are
taken into consideration when designing a dryer for your products.
You
can use such equipments from spray dryer manufacturers in India to produce milk
powder, chemical powder, enzymes, instant tea and coffees, ice cream mixes,
food powders, fruit juice and vegetable juice powders, herbals,
pharmaceuticals, detergents and mineral powder from slurry.
