Now the Spray Dryer is used widely in food, chemical, pharmaceutical, seed grain industries. The most important point of this equipment is drying.

 

Drying is a process of heat and mass transfer. What is drying？Energy is an important point. Dry material and heat sources are great important during the whole drying process, they are the important components for drying equipment，all using heat sources with gas、liquid、and solid.

According to the working principle and machine structure, it’s very important to choose suitable fuel. How to use the flue gas of burning fossil fuels, it just can be used to heat the air as indirect fuel, and to dry by using the hot air through drying medium. This technical is used for GGH, of course including fin heat exchanger, it is also normally in drying equipment.

With the development of Science and technology, types of heat sources for drying machine are increasing. With the new technical constantly improving, Tubular heat exchanger is created. Besides, the use of heating and drying medium for non-electric heating radiator is also improved constantly.

      Many companies have a lot of problems about heat sources of drying equipment. Mainly it is unmatched for dryer and heat sources. With Low heat the product will contain high moisture, and with high heat and high energy, the product cost will be increased. So dryer manufacturers need to choose suitable heat sources for drying equipment.
