Abstract: The present invention relates to a process for drying protein crystals starting from an aqueous protein crystal suspension, which comprises drying the protein crystal suspension in a centrifugal dryer, where the protein crystals, after they have been filtered off from the protein crystal suspension, are brought into contact with a drying medium which consists of a mixture of water and a nonaqueous solvent which is miscible with water in any ratio and which has a lower vapor pressure than water. In the process, a drying gas which has been moistened with water is advantageously used. The protein crystal suspension is advantageously converted into a fluidized bed for the purpose of drying.

The method includes collecting polymer-based sorbent materials containing one or more solvents, treating the waste material in a centrifugal treatment system for removing the solvents from the polymer-based sorbent materials whereby the sorbent materials have a residual solvent content that renders the materials non-hazardous for transportation to a remote recycling site. The treatment system includes a fume collection system and a centrifuge disposed in the fume collection system. The sorbent materials are charged into the centrifuge and the centrifuge is operated for extractive removal of solvents therefrom and collection of the extracted solvents. The sorbent materials are rendered non-hazardous by the centrifugal treatment system enabling the materials to be taken off site for use in making recycled parts.

Abstract: A basket or dryer liner that has the usual basket shape, i. e, generally cylindrical, but is resiliently compressible or deformable along multiple axes for reshaping into irregular shapes. It has perforate bottom wall and side walls and an open top and is generally symmetrical about x, y, and z axes that are orthogonal to each other. The basket may be manually compressed along these axes and then allowed to return to its normal shape when released. Thus, it has a noncompressed, relaxed state wherein it has maximum exterior dimensions and can stand-alone and serve the normal functions of a basket. The basket also has a compressed condition wherein at least certain of the dimensions of the basket are less than said maximum dimensions so that it can be fitted into a dryer, allowed to expand, and serve as a dryer liner. Wet clothes and other items can then be placed in the basket through the dryer opening in the normal manner.
