Plastic Vacuum Dryer for Injection Machine

Oriented plastic raw materials dry solution
As to plastic products molding, stable and optimized production process is very important to improve the product quality and production efficiency. HADRDEGA DF series hot air dryer is the best solution to get rid of the surface layer moisture from plastic raw material whose moisture absorption is weak. And it can also apply to the preheating of the raw materials, to make important process parameters to be controlled, to improve the product percent of pass, and to effectively improve the service life of molding host screw.

Hot air dryer
DF series hot air dryer has two installation forms for customers to choose, the models under DF5000 can be chosen of side hanging type, installed directly on the side wall of dry insulation material barrel, models above DF6000 are all floor type, can be installed on the bracket of dry insulation material barrel, with drying capacity range varies from 5 to 3000 kg/h. Energy consumption saving
Raw material preheating can increase the processing efficiency of the machine, also can reduce energy consumption. Using hot air dryer to preheat the raw material can save 38~40% of energy consumption than heating the raw material with the make-up machine, because with double insulation dry material barrels, and with a return air heat exchanger, can save 50~60% of energy consumption compared to ordinary dry machine.

Quality
Customers need high performance equipment to continuously ensure that they have the high quality products, HADRDEGA hot air dryer is to meet the expectations of high quality and the always insistence of the device performance under fierce price competition, HADRDEGA hot air dryer and other HADRDEGA products, are manufactured strictly according to CE standard.

Product advantage
Quality assurance for customer product
Remove the surface water from plastic raw material, preheat before entering the make-up machine
Higher production efficiency
Through the preheating of the raw material, can shorten the molding cycle of product
Low energy consumption
The energy consumption of heating the raw material in the hot air dryer is 38-40%lower than that of heating on the make-up machine 
By return air exchange system, 55-60% of the energy consumption can be saved
Simply operation
With intelligent temperature control system, self temperature setting, real-time drying temperature display and fault alarm indicator, etc
