A hopper dryer is a type of combined feeding and drying device. The enthalpy rise occurs outside the extruder, and the pellets are fed directly into the hopper. The process air is then re-circulated back through the hopper.
The hot air can also be used to pre-heat the pellets before they are injected into the mold.
A specialized hopper dryer may be suited for certain purposes.
The hopper dryer’s design provides an even distribution of dry air, which is heated by electric current. The drum can be reground and a closed loop is formed.
The hopper can be used to dry materials like non-hygroscopic resins, which are easy to process.
A hopper dryer can accommodate raw material of a variety of sizes.
The reground surface area makes it easier to process materials.
A hopper dryer is designed to heat and dry various materials. It can be mounted on a molding machine or a floor stand.
This type of drying device has a maximum temperature of 320 degrees Fahrenheit and is suitable for large amounts of plastic materials. A hopper dryer can be used to produce different types of molded products.
The hygroscopic materials require a high temperature and is suitable for drying materials that are not hygroscopic.
A hopper dryer is often used on an injection machine. The hopper can be cleaned without any difficulty, and is also very effective at drying plastics.
Its low noise blower machine seat makes it easier to clean. The hopper can also be used for dehumidifying materials.
The amorphous plastic can be molded without damaging the screw on the molding machine.
If you have a large plastic molten resin, it is best to use a hopper dryer.
A hopper dryer is a common and highly efficient way to dry resin pellets. The unit will also heat the ambient air, ensuring that the resin pellets are dried properly.
The hopper dryer uses a desiccant-free process, which is an excellent alternative to using a hot air dryer.
A hopper dryer will also allow you to save on energy because it requires less electricity.
You can run the hopper dryer by using compressed air.
A hopper dryer can be used for different purposes. The material can be dried using a variety of materials.
It can be used to dry materials for use in industries such as manufacturing. A hopper dryer has many benefits. The hood can be removed for cleaning purposes.
A hopper dryer can be positioned in a garage, or workshop. It can also be used for drying foods that can be hard to handle.
During a hot air process, the heated air from the hopper can be reused.
