Vacuum dry is to indirectly heat materials to make contained moisture evaporation under certain temperature and vacuum condition. It is the key equipment for this drying process.
The moisture content in the drying materials possibly reduced to less than 0.5% by this vacuum drying process. So, it is the optimized best drying process for heat sensitive and high purity materials drying, also, convenient for wet composition recovery.
Harrow type dryer is the most popular use vacuum dryer, ZG Model dryer produced by our company is developed based on imported Japanese technology, which is the hollow shaft harrow type dryer with best features.
1. Heat transferring area is doubled than traditional dryer, heat transferring coefficient also increased almost one times more. The evaporation efficiency in the same volume is 3 times more than traditional dryer.
2、Excellent sealing, high vacuum, absolute vacuum reaches 2mmHg. Possible remove moisture at 40℃ also convenient for recovery organic solvents.
3、Advanced agitator structure with mixing, pulverizing and drying features speed adjustable, suitable for batch and continuous production both processes.
4、Material discharge bottom valve easy open/close with self lock feature, no residue materials left.
5、The heating media for jacket and agitator: Saturated steam, heating oil, hot water. Low temperature, high efficiency dry can be achieved by using DF negative pressure steam generator.
6、Filtration screen net is positioned on the vacuum openings to avoid materials lost.
Medicine and pesticide intermediates; food additives with heat sensitivity, polymers required very low moisture contents.
