摘要： A process of both milling and drying a solvent-moist material (e.g., water-moist methylhydroxyethylcellulose) is described. The process includes, (a) providing a mill-dryer (100) which includes, in series, a heat exchanger (1), a mill (2) and a particulate separating apparatus (105) connected by conduits (8), (9) and (11, 12), which together define a mill-dryer circuit (103). The mill-dryer (100) also includes a bypass conduit (14), which provides optionally at least partial gaseous bypass of the heat exchanger (1). The process further includes: (b) introducing the solvent-moist material into the mill (2); (c) circulating a vapor stream (e.g., a steam/air stream) throughout the mill-dryer circuit (103); (d) heating the vapor stream by means of passage through the heat-exchanger (1); (e) forwarding milled particulate material from the mill (2) to the particulate separating apparatus (105) by means of conduit (9); (f) separating the particulate material from the vapor stream in the particulate separating apparatus (105); (g) forwarding the vapor stream from the particulate separating apparatus (105) through conduits (11, 12); and (h) controlling the temperature of the vapor stream by optionally forwarding at least some of the vapor stream through the bypass line (14).

摘要： The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

摘要： Described is a building material composition prepared from or having added thereto a particulate material selected from particulate polysaccharides or particulate polysaccharide derivatives. The particulate material of the building material composition is prepared by a method comprising: (a) forming a feed composition comprising a member selected from the group consisting of polysaccharides and polysaccharide derivatives, and 35 wt. % to 99 wt. % of water, based on the total weight of the feed composition, wherein said member is at least one of swelled and dissolved in the feed composition; (b) contacting, in a mill, the feed composition with a gas stream, thereby converting simultaneously the water of said feed composition into water vapor, and said member of said feed composition into a solid state form of finely particulate material; (c) separating the particulate material from the gas stream; and (d) optionally drying the particulate material. Examples of building material compositions according to the present invention include tile adhesives and joint fillers.

摘要： The present invention relates to a new, particularly economical process for producing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a carrier and heat exchange gas, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The particulate cellulose derivative is then separated from the heat exchange gas and carrier gas, and optionally dried. The mill drying and the particulate cellulose derivative product are influenced by establishing a specific water content in the swollen and/or dissolved cellulose derivative.
