Abstract
A system and a method for reducing the level of moisture of fluent materials or wet solid materials, characterized in that the material to be treated is provided in a particle form and then exposed to a relatively high volumetric flow of gas treating medium which is drawn through the material so as to force the moisture in the center of each individual piece to migrate towards the periphery thereof where it can be easily evaporated. Air at ambient temperature may be used as gas treating medium so as to minimize the level of energy required to provide an efficient drying operation.
Claims17
A high vacuum, low temperature drying process for reducing moisture content of a moist pasty material having an external exposed surface, comprising the steps of:
- providing said moist pasty material in the form of pellets;
- and drawing by vacuum at a low temperature and at a rate of at least 2 CFM (0,0566 m3/min.) per square inch (6,45 cm2) a gaseous drying medium through said pellets from an upstream side to a downstream side thereof, said rate being sufficient to reduce pressure on the downstream side of each pellet, thereby causing moisture located in a central portion of each of said pellets to migrate towards said downstream side thereof.
