Abstract:

A vapor dryer system in which products to be dried are positioned in a tank and immersed in a hot vapor cloud and saturated with hot vapor, which removes water from the surface of the product as the vapor condenses on the surface. The condensate is collected and diverted to preserve the purity of the solvent reservoir. The vapor is formed from a liquid reservoir which is heated by heat transducer means disposed remotely from the tank to minimize the risk of igniting the vapor.
