Coffee drying equipment mainly includes spray dryer. Spray dryer is widely used equipment in drying industry and liquid composite molding. Particularly, it is suitable for producing powder, granule or block solid products from solution, emulsion, suspending liquid pump past liquid. Therefore, when the require granule size, left moisture content, stacking density and granule shape must be controlled precisely, spray drying is a very ideal technology.
After being filtered and heated, the fresh air enters into air distributor which is on the top of the dryer. The hot air in spiral enters into the drying room. When liquid raw materials passed through the high speed centrifugal sprayer on the top of the tower, it will rotate and sprayed into the extreme slim mist liquid beads. Raw materials can be dried to required products instantly while they contact with hot air. Finished products are discharged continuously from the bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.
