Circulation/Fresh Air Ovens design examples

APPLICATIONS

These dryers are suitable for various application within industrial drying:

  • drying of synthetic granulates
  • annealing of synthetic components
  • heating of various parts out of metal, rubber, ceramic, paper, etc.

We select for every drying job the perfect air guidance. According to customers

  • component size
  • component arrangement
  • loading capacity

we select either vertical, horizontol or double-sided air guidance.The best flow possibility of the parts inside the dryer will be allways considered. If steam, moisture or similar will be release durching the drying or annealing process dryers with fresh, circulation or exhaust air slides are recommended. A continuous adjustable ventilation flap system is feeding fresh air equal volumes of exhaust air will be steamed out with a tube socket. This exhaust tube socket can be enlarged with tube to lead the saturated air outside. There are drawers, support bearing with perforated plates or complete supporting racks for loading inside. The Dryer has 100 mm high foods which allows an easy loading with a lift truck. Dryer designs with base plates allow a direct loading/access to dryer with racks. For subsequent temperature improvement we offer adustable shutter plates at air entering side. The adjustment is as per requirements. There are as well solution for limited space available.  Dryers in two-parted designs can pass small doors to be placed and fitted at the correct spot. For an already realised project we "put a dryer aside" to achieve maximum internal tank heights with limited alignment height. See design example 3 - part# 2008235.
