Method for ensuring high vacuum by continuous vacuum plate dryer
Sep 03, 2018

The continuous vacuum plate dryer is a drying device suitable for heat sensitive materials with low drying temperature requirements, such as medicines, vitamins, biological products, enzymes, solvent-containing materials, and the like. At the beginning of drying, the wet material is added to the quantitative loader capable of withstanding negative pressure, and the empty pump is turned on, so that the vacuum tray continuous dryer is in a negative pressure state, and the material is evenly added into the dryer through the continuous locker. Dry work.

 

The dried material in the continuous vacuum plate dryer is discharged from the discharge port at the bottom of the dryer, and the moisture escaping from the material is recovered through the condenser and the solvent receiving tank, and the whole operation is carried out under a negative pressure. Repeatedly, the dry material is continuously discharged to the outer packaging of the dryer.

 

The material enters the feeding hopper, and at the same time, the pneumatic ball valve of the continuous vacuum plate dryer is simultaneously opened, and the material in the feeding hopper enters the feed transition silo; at the same time, the material in the feed transition silo 2 is under the action of the stirring device After entering the dryer, the pneumatic ball valve is closed at the same time; at the same time, the material in the feed transition silo enters the dryer under the action of the stirring device.

 

The dried material in the vacuum tray continuous dryer enters the inlet of the pneumatic ball valve under the action of the file, the pneumatic ball valve is simultaneously opened, and the dry material enters the discharge transition bin, so that the dry material is continuously discharged to the outer packaging of the dryer.
