Features of 2-tank dehumidifying dryers
With the 2-tank system, the operation rate of IMM increased!
- Since the dryer has 2 tanks, while the IMM is running, it is possible to prepare for the next molding operation by operating the tank not in use.
- Cleaning or pre-drying can be started then, which helps increase the operation rate of IMM.
Cost and space for the standby dryer saved!
- With two tanks, there is no need to have another dryer for pre-drying.
- Since setup is possible with one unit, cost and space can be saved.
Attachment and detachment time of material hoses dramatically shortened with one-touch coupler!
- One-Touch coupler significantly shortens the time it takes to change hoses after completion of molding.

Rich loading variations
Standard loading circuit
- By using the standard loading circuit, material of 100Kg or more capacity is dried and loaded to one IMM.

Loading variation example
Until now ...
when using two dryers,
• the cost was high
• space was required
• transportation was a big problem
In the case of a 2-tank dehumidifying dryer
Since the dryer has 2 tanks, while the IMM is running, it is possible to prepare for the next molding operation by operating the tank not in use. Cleaning or pre-drying can be started then, which helps increase the operation rate of IMM.
Helical Hopper Specifications
- Resin material is separated into "powder" and "material" by the spiral airflow and agitation airflow generated in the hopper.
- This equipment thoroughly removes dust.
Structure and Principle
While rotating the resin material transported in a fixed quantity in the hopper, the fine powder contained in the resin material is collected from the air suction port at the top of the hopper to the collector side.
At this point, agitation air is sent from the bottom of the hopper, and the resin material is fed back into the hopper by the delivered air and the fine powder adhering to the surface of the resin material is repeatedly removed.
Features
- The hopper collects the dust in the material conveying line and keeps the occupying space to the minimum.
- The air swirls in the hopper to isolate and collect the pellet dust efficiently.
(The hopper is also usable for quick mixing of crushed materials.) - Upper filter shape and size are changed. Achieves the best dust collection.
Other Features
Higher efficiency in setup! Higher level of cleaning work!

Easy drum opening and closing for efficient cleaning

Reinforced hinges make it possible to tilt the drum very down further, thus increasing efficiency in cleaning significantly.

Without using any tool, hoses are changed easily. Time to attach and detach hoses is dramatically shortened.

Operator's safety ensured
Hand or finger pinching accidents prevented by the automatic material shutter with a sensor and limit switch

The opening/closing of the automatic material shutter is stopped automatically.

Stop air supply to the automatic material shutter.
Various mechanisms that contribute to work efficiency


The improved separator shortens the time it takes to increase temperature, realizing drying efficiency higher by approx. 10% than our conventional models.

The capacity is adjusted with the material level gauge to reduce the work of discharging excessive material significantly.
Other features that contribute to increased productivity
Controller
- 7 inch type wide color indicator adopted
- Making it possible to present visual information using colors

The operation screen adopting the navigation function helps operate various loading patterns with ease.
Icons and illustrations realize the co-existence of ease of use and visual clarity.
Closed conveying, in which conveying is performed in a sealed condition, eliminates air intake and shuts out moisture absorption from the outside air. More thorough drying is possible.
Total Link provides integrated control of settings, startup, and monitoring of peripheral equipment
Using HARMO's Traverse, batch setting, startup, and monitoring of peripheral equipment can be performed in a batch.
For example, a take-out robot can be used to set peripheral equipment placed outside the clean room.
There is no need to leave the clean room to change temperatures, etc. This contributes to improving productivity by saving time and preventing human error by reducing the operator's workload.
