Abstract: A system for the in situ production of a liner suitable to shield active surfaces of apparatus for the processing of liquids and/or solids from coming into contact with, and being fouled by, the processed materials, comprises: 1) a spray head, adapted to spray a layer of curable polymeric material onto a surface; 2) circuitry adapted to direct the movement of said spray head according to data pertaining to the surface to be sprayed; and 3) curing apparatus, suitable to cure the layer of material sprayed onto said surface, thereby to produce a shielding liner in situ.

Abstract: A device for the processing of liquids and/or solids includes a disposable layer adapted to shield a working surface from coming into contact with, and being fouled by, the processed liquids and/or solids, and apparatus suitable to apply a negative pressure in a gap between the disposable layer and the working surface, thereby causing the disposable layer to adhere to the working surface.
