Vacuum Drying From Pharma to Bulk Polymers: Vacuum Oven Tray Dryers and Rotary Dryers
Italvacuum is one of Europe’s best-known manufacturers of vacuum dryers and vacuum pumps for pharmaceuticals, fine chemicals, chemicals and cosmetics. This article discusses the company’s Multispray cabinet dryer, the Tumble rotary cylindrical vacuum dryer and the Saurus939 range of vacuum pumps.
With more than 70 years of know-how in vacuum process applications, Italvacuum supplies not only turnkey drying units but also bespoke systems to customers’ specifications. The company’s products comply with all the main European regulations (CE, Atex and PED), plus the increasingly stringent FDA and cGMP rules. At its facility in Borgaro/Italy Italvacuum has a wide range of test units for laboratory-scale and semi-industrial drying trials. Scale-up tests backed up by advice from the company’s experienced staff allow reliable prediction of the required dryer size and allowable filling level, and of how the full-scale drying process will perform in terms of drying time, particle characteristics, and particle size distribution.
Cabinet Dryers for Clean Room Installation
The Multispray Cabinet Dryer is a vacuum oven-type tray dryer. Both the enclosure and the individual shelves are heated by circulating heat transfer fluid, thus guaranteeing uniform temperature distribution with no cold spots or risk of condensation. Other features of the Multispray Cabinet Dryer include:
- mirror-polished finish inside the cabinet and on both upper and lower surfaces of the shelves;
- watertight door seal;
- smooth, crevice-free trays for complete recovery of powders; and
- clean room installation, with the rear of the dryer accessible from a separate machine room.
The dryer is available with either fixed or removable heating plates. In the latter case, heating plates can be removed and replaced quickly and safely with the aid of a separate hydraulic trolley, made entirely from stainless steel and fitted with anti-static nylon wheels.
