Features
1. Hopper dryer that achieves uniform hot air control
The outside air taken in by the blower passes through a heater section with rectifying measures and is dispersed evenly from the discharge port. By optimizing the flow of hot air, it is supplied evenly throughout the entire inside of the hopper, minimizing the difference between the set temperature and the resin temperature.
The hopper also features Matsui's unique diffuser cone, which provides a gap between the cone and the hopper wall, promoting mass flow and preventing bridging while discharging materials uniformly.


When handling long fiber materials used for large or high strength parts, the material tends to clog in the hopper, which is a problem.

Long fiber materials made by compounding glass fiber or carbon fiber with thermoplastic resin tend to have fibers that tend to tangle and form bridges.

This can result in a shortage of material, which can lead to problems such as material burning, abnormal measurement in the molding machine, and Overheating of the screw.

Our unique diffuser cone improves the flow of material in the hopper and prevents bridging, ensuring a stable supply of material and reducing molding problems.
2. Dual safety mechanism prevents heater Overheating
If a heater Overheating alarm occurs, a voltage tripping (SHI) breaker will trip and cut off the power supply. By quickly shutting down the device in the event of an abnormality, damage to the heater and surrounding equipment will be prevented. In addition, an external Overheating prevention device is included as standard equipment as a safety device independent of the temperature controller.
In this way, the dual safety mechanism ensures high safety even in the unlikely event of an abnormality.

3. Reduced heat dissipation for energy-saving operation
The heater box has a double structure that combines heat exchange and insulation performance.The lower part of the hopper, which is the hottest part in the equipment, also has a double structure, which significantly reduces heat radiation to the outside.
This allows the energy of the heated air to be used efficiently for drying, and reduces unnecessary heater output. Reducing heat loss contributes to energy-saving operation while maintaining stable drying performance.
4. Maintenance structure that allows quick cleaning of the inside of the hopper
The small hopper has a structure in which Cylindrical section opens around a hinge, improving access to the inside.The medium and large hoppers are equipped with a large-diameter cleaning window, so the inside of the hopper can be cleaned simply by opening the door.
By using a cleaning method that suits the hopper size, maintenance work can be done with just one touch. This reduces cleaning time and workload, and makes daily inspections and setup more efficient.

5. Long-life sheet filter that protects factory environment
To keep factory environment clean, a sheet filter that is easy to attach and detach and has a long life is included as standard. The structure allows for easy daily inspection and replacement, reducing the burden of maintenance work. Maintaining cleanliness around the equipment supports stable operation and maintaining quality.
