Drying System




Hopper Dryer

Hopper dryers offer an effective and low-cost method for plastic material drying. Hot air is used to dry wet materials due to moisture absorption during packaging, transportation, and recycling cycles. They can be directly installed with the moulding machine for quick drying and space saving. For this series, hot air blows evenly from hopper bottom to the top, with hopper capacities range from 12 to 1000kg. All models can be supplied with optional 24 hours auto-start timer.
Features

Adopt hot air diffuser to gain an event hot air flow to improve drying efficiency

Designed hot air inlet elbow can prevent dust piles up at bottom of the pipe heaters so to avoid burning

All material contact surfaces are made of stainless steel

Separable hopper base gives easy access to hopper tank for the convenience of material changing and cleaning
Proportional deviation indicative temperature controller for accurate temperature control
Overheat protectors to prevent accidents by human error or mechanical faults
Quick cooling blower and outfitted power switch
Overheat indicating light, motor contactor and overload relay are equipped standard
All models have preheat timer and double insulated hopper as options
Other optional accessories include ‘N’ like floor stand, dried-material suction box, hopper magnet, magnetic base, hot air recycle, blower inlet filter, exhausted air filter, and cyclone dust separator etc


Hopper Dryer (B series)






Hot Air Dryer
Europe Design, CE Version

Hot Air Dryer adopts down blowing air-diffuser design and use stainless steel material hoppers to avoid contamination. With this design, they are also ideally suited for use with honeycomb dehumidifiers to dry engineering plastics. There are 25 models, ranging from 20 to 8000 liters with airtight material cleaning doors SHD-80U and above. The microprocessor control featuring digital display and auto start/stop timer are equipped as standard.
Features

Innovative design with sleek appearance

Hot air down-blowing design ensures even distribution of hot air to maintain a steady temperature in the hopper and increase drying efficiency

All material contact surfaces are made from stainless steel

Material clearance door seal and makes clean down more convenient and effective. (Models SHD-80U and above)

Microprocessor is used for accurate temperature control.

Overheat protection to ensure reliable operation

Digital P.I. D temperature control with LED display

7 days automatic start/stop timer to improve energy saving

Equipped with main power switch and control switch

Aluminum base as standard equipment, stainless steel as an option

Option accessories: magnetic base (aluminum or stainless steel), mobile floor stand, suction box, hot air recycling, exhaust air filter, blower inlet filter, etc





Hot-air Dryer & Autoloading System
Europe Design, CE Version

This series of hot air compact dryers combines conventional hot air drying and two-stage conveying functions in a compact unit, and is particularly suitable for using with the big tonnage moulding machines when height restriction is concerned at the workshop. This series has a unique function of two-stage conveying, that can transport both raw material to its own drying hopper and dried material to the processing machine. Insulated drying hopper features hot air down-blowing and cyclonic exhausts design, this improves drying efficiency and reduces energy consumption whilst maintaining a steady drying effect.
Features

Innovative design with an eye-catching semi-integral appearance

Each model combines hot air drying and two-stage conveying functions into a single unit

Compact in size for ease of movement and space saving

Insulated drying hopper features hot air down-blowing and cyclonic exhaust design, this ensures even distribution of hot air to maintain a steady temperature and increase drying efficiency

All air and material contact surfaces on the drying hopper made from stainless steel to a void contamination

Accurate control and display of regenerating temperature using P.I.D control with LED display

Double overheat protection to ensure reliable operation

7 days automatic start/stop timer to improve energy saving

Two-stage conveying system can transport both raw materials to its own drying hopper and dried material to the processing machine

Closed-loop conveying device eliminates the possibility of moisture re-absorption during dried material conveying. Machine equipped with pneumatic shut-off valve ensure no material remains in the material line after each loading cycle

Optional hot air recycling device can reduce up to 30% of the energy consumption, and gives a dust free environment





Cabinet Dryer

Cabinet dryers are mostly used for simultaneous drying of different kinds of polymers in small quantities or for drying materials for trial moulding. They are also found applications in electronics, electric machinery, electroplating, pharmacy, paint baking, printing industries, etc. for preheating or drying related products.
Features

Accurate P.I.D temperature control to achieve an even drying effect

Air-proofed insulating door can maintain temperature constantly inside as to reduce energy consumption

Stainless steel tray and liner bring no contamination to materials

Optimizing design for ease of maintenance and servicing

Designed flexible and adjustable air inlet and exhaust

Overheat protector can prevent excessive drying

Motor overload delay

Ampere meter and main switch installed on control panel

24 hours timer, easy to operate

Visible alarm to indicate emerging troubles

Tray Size and inner dimensions of the dryer can be specified according to requirements
