Thermal Fin Vacuum Dryer DPD3.1

DPD3.1 is Thermal Fin Vacuum Dryer. The reduced pressure space allows for short drying times at low temperatures. It prevents yellowing of products caused by oxidation, and reduces the maintenance frequency of the mold surface by removing gases.

Features

1. Vacuum drying prevents yellowing!

Drying environments such as high temperature drying or long drying times for pellets accelerate the thermal degradation of resin raw materials, which is one of the causes of discoloration, and cause yellowing. The vacuum heat transfer method utilizes a vacuum space where the boiling point of water is lowered, making it possible to evaporate water at a low temperature. Therefore, the DPD3.1 makes it possible to dry resin in a short time without raising the temperature as much as possible.

2. Short drying time reduces heat deterioration!

The hopper internal transfer fins are installed on the outer periphery and center and the temperature is controlled separately. This allows efficient heating and drying in a short time.

3. Improved transport control operability!

For many raw materials, the batch amount for secondary transport must be adjusted. In conventional machines, this was done by adjusting the valve. Therefore, in the DPD3.1, we have improved the batch amount by setting the touch panel, improving operability during material transport.

4. Equipped with air shock function, it solves problems such as bridges and blocks!

Some plastic raw materials are prone to bridging and blocking. The DPD3.1 comes standard with an air shock function for the initial drying stage, which solves these problems.

5. Energy savings are achieved through drying by reduced pressure and improved insulation specifications!

Energy saving through "reduced pressure drying"

Resin is heated by heat transfer rather than by hot air, and dried by reduced pressure. As a result, energy consumption is roughly half that of conventional dehumidifying dryers.

Energy conservation through "improved insulation specifications"

Compared to previous models, we have improved energy efficiency by improving insulation in every detail and preventing heat loss.

6. Contributes to reducing maintenance time and frequency!

Reduced maintenance time

The use of a lift and large discharge gate allows for quick removal and replacement of materials. In addition, the use of extruded materials gives the material a smooth surface with almost no resin adhesion, making cleaning easy.

Reduced maintenance frequency

This dramatically reduces the amount of film-like deposits on the mold surface, which can be a problem when molding gaseous materials, and significantly cuts down on the frequency of mold maintenance.

Precautions for installing drying equipment

  1. According to Article 14 of the Industrial Safety and Health Act and Article 6-8 of the Industrial Safety and Health Act Enforcement Ordinance, the business operator who uses power as a heat source for heating and drying is stipulated that a drying equipment work chief must be appointed from those who have completed the skill training for the drying equipment work chief when using and operating drying equipment with a rated power of 10 kW or more. As the skill training for drying equipment work chiefs differs depending on the prefecture, please contact the prefectural labor bureau (labor standards inspection office) in your jurisdiction.
  2. According to Article 88 of the Industrial Safety and Health Act and Article 6-8 of the Industrial Safety and Health Act Enforcement Ordinance, the business operator who uses power as a heat source for heating and drying is stipulated that the notification must be made to the Chief of Labor Standards Inspection Office at least 30 days before the start date of the construction when installing or relocating the drying equipment with a rated power of 10 kW or more and when changing the main construction part.
  3. According to Article 45 of the Industrial Safety and Health Act and Article 15, Paragraph 1, Item 7 of the Industrial Safety and Health Act Enforcement Ordinance, the business operator shall conduct a periodic self-inspection of the drying equipment and keep the record for three years is stipulated. (Related: Industrial Safety and Health Act Enforcement Regulations Article 299)
  4. Drying equipment may require notification to the fire department depending on the municipality. Please contact your local fire department.
