<p>Agricultural products such as bulbs, roots, fruits, etc. are ground into a fluidised mass by treating them, without the spaces between them being filled with water or other fluid, and in an atmosphere poor in or without oxygen. For pref. the products are ground or grated in a vacuum. Alternatively they may be processed in an atmosphere of an inert gas or of a reducing gas. The gas is drawn off with the ground product, is separated from the mash, and is recirculated to the chamber where the treatment takes place. To eliminate the inconvenience and the problems of grinding or grating in the presence of a reducing gas such as SO2. The product is not diluted with excess water, and there is no corrosion as occurs with SO2.</p> |
