Hopper dryer Introduction:
Hopper dryers can also be called ordinary dryers, which are the most economical dryers for dry plastic raw materials. This hopper dryers can be used together with the injection molding machine, simple and efficient! Hopper dryer is standard hot air dryer replacement products, based on the original features fully take into account environmental factors, to be improved. It can dry raw materials that are damp due to packaging, shipping or recycling.
Hopper dryer works:
In the raw material processing, the hopper dryer blows the constant high temperature wind into the drying barrel through the drying fan, and after the raw materials are baked, the original moisture in the raw material in the barrel is taken away to achieve the purpose of removing the moisture contained in the raw materials. The air blown by the fan turns into a high-temperature dry hot air after electric heating, and the hot air can be uniformly dispersed in the dry air drier by the screen protector and the hole screen. Optional hot air recovery device, the wind blowing through the return air filter into the dry fan to form a closed loop, saving electricity.
Hopper dryer application area:
Hopper dryer is the most effective and economical model for drying plastic materials, which can dry the raw materials that are damp, packed, transported or recycled. The straight-through design is particularly suitable for direct mounting on plastic molding machines for drying, both fast and space-saving. This type of blowing hot air dryer can provide a charge of 12 to 1,000 kg, is divided into thirteen models.
Hopper dryer features:
1, the use of uniform distribution of hot air of high-performance hot air diffusion devices, plastic drying temperature to maintain uniform, increase drying efficiency.
2, unique hot air pipe design, can avoid the accumulation of dust at the bottom of the electric heater, causing the combustion.
3, barrel and internal parts are made of stainless steel.
4, barrel separation from the bottom, clean the material convenient, fast material change.
5, the use of proportional deviation temperature controller can accurately control the temperature.
6, a double overheat protection device, can reduce the human or mechanical failure caused by accidents.
7, a variety of models are available preheating timing device, microcomputer control, and double insulation barrel selection.
8, all digital P.I.D control LED status display.
9,0-99 hours timer automatically boot.
10, to provide intermittent drying methods, in order to achieve the purpose of saving electricity. (8-10 SHD-DT series only)
11, transparent window type magnet base.

Hopper dryer maintenance and care:
1, the filter clean up. Air inlet filter should be regularly checked, cleaned regularly, when the filter is blocked, the amount of air intake decreases, affecting the drying effect.
2, splitter cleaning: replacement of raw materials, the separator to wipe clean
3, the clean-up of the dust chamber: In the drying process, the powder material fall into the dust collection room for a long time accumulated, so need to regularly remove the drying chamber can be opened and start the fan, the use of wind blowing the powder.
4, the screen raw material caking cleanup: If the temperature is too high due to some reason, the raw materials caked in the screen when the material can not fall, this time prohibited the use of hard objects such as iron stick scraping to protect the screen separator by Loss, remove the barrel decomposition.
5, Shutdown: very hot after switching on and off, and then close the fan to ensure that the heating tube is fully cooled to extend its life.
Dry hopper installation and use:
The company is located in:
1, Installation: After drilling the base of the dryer, stand upright on the inlet of the injection molding machine and fasten it with fastening screws.
2, Connect the power: Open the power distribution box, connect the power supply with reference to the wiring diagram, should pay attention to whether the power supply voltage is consistent with the local, the power switch specifications and load protection rated is appropriate, and start the fan to see if the direction of rotation with the fan superscript Direction, the electrical box on the back of the box with "┷" grounding mark on the bolt connected to the wire and properly grounded.
3, temperature regulation: reference to the drying temperature of plastic raw materials reference table, set the thermostat temperature based on practical experience.
4, the air volume regulation: generally all open, in case of material storage bucket when the material is not long, or when the need for higher temperature, the discretion of small air volume, or can not achieve the desired drying effect.
5, raw material filler: filler to ensure that the material content of not less than 70%, but not too full, so as not to pressure the lid, affecting the drying effect.
6, the transparent drying of raw materials: the drying of transparent raw materials must be installed in the air inlet filter (the original sponge, etc.) to prevent dust in the air to enter.
7, Preheat the bucket: Before the input of raw materials, the bucket is heated first, so that the internal moisture drying, preheating time 10-20 minutes.
