Gruenberg manufactures granulation dryers from 15 to 800 cubic feet of chamber capacity. Steam units aerated up to 90C, and electric units are available up to260C. Two types of circulation systems are standard: controlled recirculation and single-pass systems. Download the brochure (scroll down) to see complete details.

Gruenberg Granulation Dryer Construction
Granulation dryers, just like the dry heat sterilizers, are built around a welded structural steel frame for long-term reliability. All interior surfaces are constructed of 100%continuously welded stainless steel for quick and easy wash downs. To simplify cleaning, both side walls are removable, and as an option, the floor may be sloped to a drain. Radius corners are optional. The exteriors can be either painted cold-rolled steel or stainless steel depending upon your needs. Between the interior and exterior walls are over 3" of high-performance insulation.

Granulation Dryer Airflow Optimized for Pharmaceutical Processes
Distinct perforated walls provide for a superior temperature uniformity of 2C. Every Gruenberg granulation dryer is fully tested for airflow and temperature uniformity by a multi-point strip recorder prior to shipping.

Controlled Recirculation & Single-Pass Airflow Options
Controlled recirculation is the most common means of handling airflow in a granulation dryer. Heated air is passed over the product; before some of the air is exhausted, much of it is recirculated, reducing energy consumption. Temperature uniformity for controlled recirculation is more stable than in single-pass systems.

Single-pass systems heat the air, filter it, pass it across the load, then totally exhaust it. This system was developed for use with high alcohol or flammable liquid mixes.

Complete HEPA Filtration
HEPA filters, 99.97% efficient, at 0.3 microns, are installed on the fresh air intake and the exhaust of our granulation dryers. A disposable pre-filter is installed upstream of the intake HEPA filter to remove larger particles and to extend the life of the HEPA filter. As the dryer cycles off, the exhaust HEPA filter prevents particles from entering back into the process chamber.

Granulation Dryer Controls
Controls for granulation dryers can be configured to your application review the Gruenberg brochure for more complete details.
