Microwave drying plant, heated and dehumidified air passed through microwave drying chamber

摘要

A dehydration plant has a chamber 2 through which articles to be dried are transported on conveyors 3. The articles are dried by irradiating them with microwaves. Heated, dehumidified air is circulated through the chamber 2. The air may be dehumidified by passing it over the evaporator of a compression refrigeration machine. Heat extracted from the air in the evaporator may be used to heat the air stream by passing it over a condenser. The air may also be heated by an outside heat source, for example, steam passing through heat exchanger tubes mounted in the air stream.
