Baking Soda

The use of carbon dioxide closed loop and low-temperature thermal medium drying process greatly improves the quality of baking soda products, while reducing exhaust emissions and improving the quality and environmental protection.

The wet material from the centrifuge enters the fluid bed dryer through the mixer, feed screw conveyor and feed locking valve in sequence. Under the action of fluidizing wind, the material is fluid movement. In the drying bed, the heat exchanger is fed with hot water as the heat source, and at the same time, the hot air heated by the air heater powered by the drying fan is used as the fluid air in the drying bed. Hot water and hot air at the same time to provide heat for the material drying, so that the material warming and dehydration. After drying the material into the cooling section. In this section, the heat exchanger passes circulating cooling water. At the same time, the cooling section of the fluid air using lower temperature natural air. Cooling water and air both for the material cooling to provide cold, so that the material cooling. The cooled material is discharged from the fluid bed dryer discharge port by the discharge rotary valve.
