Granulation Dryers

Gruenberg Granulation Dryer

Product details

Gruenberg designs and manufactures granulation drying equipment that is built with a welded structural steel frame for longterm reliability. All interior surfaces are constructed of 100% continuously welded stainless steel for quick and easy washdowns. Steam, hot water, or electrically-heated granulation dryers are rated up to 90°C. Gruenberg's granulation drying equipment is available with two standard types of circulation systems: controlled recirculation and single-pass systems.

Key Specifications

  • Temperature Range: typically up to 85°C (185°F)
  • Uniformity: ±2°C
  • Chamber Size: 15 to 800 cubic feet

Performance

  • Maximum temperatures: typically up to 85°C (185°F)
  • Dryer Uniformity of ±2° at 50°C (122°F)
