Abstract
1,220,212. Drying with desiccants. R. A. P. WERTHEIM. 18 Aug., 1969 [16 May, 1968], No. 23406/68. Heading F4G. A dehydration process comprises the steps of forming a product for dehydration into a layer and bringing the layer into close proximity to a desiccating material or materials. The product may be in plastic, granular, powdery or viscous form and may be moulded or extruded into a layer or supported by a mesh. The product to be dried may be sandwiched between layers of desiccant and separated therefrom by water permeable layers such as rayon or parchment. The sandwich may be included in a polythene bag so that it may be subjected to a vacuum or pressure or a special gas. Air circulation may be provided to avoid stagnation. The sandwich may be rotated to induce a tumbling movement in the product. The product may be milled or otherwise broken up before and or after drying. For continuous operation the product may be extruded on to a number of individual trays or a continuous conveyer belt which passes past a desiccant. The process may be used for drying yeast, cream, fruit or other vegetable products which may be pretreated by filtering or freezing and thawing. Yeast is chilled to no more than fifty degrees Fahrenheit.
