Vacuum Harrow Dryer,(Vacuum Rake Dryer) The machine is a horizontal intermittently working dryer, the wet moisture will be vaporized through heat conduct from the harrow, the moisture will be suck out by vacuum pump.

1， The hot conduction plane through with the heat was conducted to materials to be dried is very large and therefore the machine have a relatively high efficiency of drying. 2， Due to the harrows was churn up inside the machine, so the heat was evenly scattered into the materials. 3， The mix round harrow is suitable for paste and mushy state material.

Materials with state of paste, powder, starchy and those which is heat sensitive and need to be dried under low temperature and those materials which is easy oxidized, easy explode, or poisonous and also those which the menstruum need to be collected.
