专利汇可以提供Method and apparatus for drying stillage专利检索，专利查询，专利分析的服务。并且Stillage is flash dried in a drying conduit and chamber system by passing large volumes of air through the system having entrance temperatures in the range of about 325*F to about 425*F. Stillage material is rapidly circulated through the system a plurality of times. Water is separated from the stillage during each drying pass to form a dry (about 10% moisture content) nutrient food substance without emitting significant amounts of smoke or odors.，下面是Method and apparatus for drying stillage专利的具体信息内容。

权利要求

1. A method of drying moist stillage material composed of moisture and moist particles having moisture pervaded throughout the particles comprising a. maintaining a rapidly moving gas stream emanating from a heat source and moving to one or more gas-stream and particulatematter separator means which gas stream includes a columnar portion and is heated to a temperature sufficient to volatile moisture on and at the surface area of the particulate matter mixed therewith; b. continuously introducing non-fluidized material into the columnar portion of the stream to cause the material to be mixed with it and heated by it; c. causing the material to move a substantial distance along with the stream during which movement moisture on or at the surface area of the particulate matter is removed; d. separating the material from the gas stream; e. collecting the separated material; f. conveying and handling the collected material for a sufficient time to permit moisture in the interior of the particulate to migrate to the surface area; g. introducing a substantial quantity of the treated material in non-fluidized form back into the columnar portion of gas stream after said moisture migration; and h. repeating the above steps until the material has been substantially dried, whereby the stillage is progressively and incrementally dried at temperatures that avoid any substantial reduction in the nutrient value of the stillage and without emitting significant amounts of smoke or odors.

2. The method of claim 1 in which the gas stream has a temperature of from about 425*F to 150*F.

3. The method of claim 1 in which the gas is air;

4. The method of claim 1 in which the gas is superheated steam.

5. The method of claim 1 in which the gas is a mixture of gases.

6. Apparatus for drying spent stillage comprising a. an elongated drying conduit; b. gas pumping means for pumping a gas at high speed through the conduit; c. non-fluidized stillage introducing means for introducing the non-fluidized stillage into the conduit as gas passes through the conduit; d. heating means for heating the gas prior to its entering the conduit; e. separator means associated with the conduit for separating the material from the gas after it has travelled a distance in the conduit; and f. recirculating means for introducing a substantial portion of the material back to the stillage introducing means while diverting a portion of the material to a separate location.
