Vacuum tray dryer to adapt to materials:
Closed recovery solvent tray continuous dryer process is suitable for the recovery of solvent drying process and the moisture is flammable, explosive, toxic substances, can not be directly discharged into the atmosphere, the recovery process must be dried. Such as wet parts of methanol, ethanol, gasoline, pyridine, petroleum ether, halogenated hydrocarbons, acetone, formaldehyde and so on. On the basis of the basic configuration, adding a continuous material out of the stopper, condenser, solvent receiving tank and vacuum pump. The moisture (solvent vapor) escaping from the desiccator enters the solvent back from the top of the desiccator

Close the condenser, the cooling medium in the cooling of the condensate into a solvent liquid, into the solvent receiving tank, not

The condensate gas leaves the solvent receiving tank and is evacuated by the vacuum pump. Cooling medium should be based on the characteristics of the solvent, the choice of cooling water or cold brine.

Vacuum Dish Dryer Nitrogen Gas Replenishment Principle: The nitrogen-circulating disk-type continuous dryer process is suitable for particularly susceptible to oxidation, especially for flaming, explosive and highly toxic substances. On the basis of the basic configuration, equipped with solvent condensers, solvent receiving tank, inert gas recycling machine, fin heater, inert gas tank and other equipment. Wet material from the quantitative feeder through a continuous stopper added to the dryer, from top to bottom movement to complete the drying process. Dry material is discharged from the bottom of the dryer through a continuous stopper. The moisture which escaped from the material enters the condenser from the top of the dryer to condense into a liquid and flows into the solvent receiving tank. The cooled inert gas is sent to the dryer by a circulating machine Inside the device, absorb the wet material into the condenser to re-cool, forming a closed loop. The inert gas is preheated by the fin heater before it enters the dryer. The inert gas tank replenishes the system with depleted nitrogen.
