Hot Air Hopper Dryers
HD series hopper dryers offer a effective and low-cost method for plastic material drying.Hot air is used to dry wet material.Hot air is used dry wet materials due to moisture absorption during packaging,transportation,and recycling. They can be directly mounted on the moulding machine for quick drying and space saving.For this series,hot air blows evenly from bottom to the top（both GHD-800 and GHD-1000 have down-blowing air pipe and accessible door for easy material clearance）of the hopper with capacity ranging form 12kg to 1000kg.all models can be supplied with optional 24 hours auto start/stop timer.
2. Hot Air Hopper Dryers Features
1.Adopt hot air diffuser to gain an even hot air flow to improve drying efficiency.
2.Hot air inlet elbow design can prevent dust piling up at bottom of the pipe heaters so sa to avoid burning.
3.All material contact surfaces are made of stainless steel to eliminate material contamination.
4.Hopper separated from its base, ensuring convenient cleaning.
5.Proportional deviation display thermostat for accurate temperatur control.
6.All series are equipped with exposed power switch.
7.Equipped with excitation tripping overheat protection, making machine operation secure and reliable.
8.Overheat tripping can automatically cut off power when drying temperature exceeds set deviation value.
9.Cyclone dust separator, exhaust filter, magnetic base and blower inlet filter are optional.
10.Hot air recycler, suction box, hopper magnetic, N type floor stand and storage hopper are optional.
11.24-hour auto start/stop timer is optional.
3.Hot Air Hopper Dryers Application
（一）HD Direct Mounting
（二）HD Floor Stand Mounting
4.Hot Air Hopper Dryers Working Principle
In the drying process, hot air with constant temperature is blown by a blower a two-layer insulated hopper to dry the materials. Moisture will be separated out and taken away by hot air, thus to gain a satisfied drying effect.
Air blown out of blower became high temperature drying air after being heated. Through screen protector and hole screen, hot air can be equably dispersed in the material of storage tank (see piture), Hot air recycler is optional so the air enter drying blower after being filtered to form a closed loop circle and save electricity.
5. Hot Air Hopper Dryers Specifications Table
