专利汇可以提供Method of and means for flash drying naturally occurring oilseeds专利检索，专利查询，专利分析的服务。并且Oil and protein bearing naturally occurring seeds, beans, such as cottonseeds, rapeseeds, soybeans, high in moisture content and not suitable for storage, are subjected to a process which involves the reduction in the surface moisture and absorbed water content of the solids material to the desired moisture content at an accelerated drying rate, utilizing flash drying, which is suit-able, and safe, for storage and for future processing of the afore-mentioned Earth produced materials. The method and means involves specially designed equipment employing heated gases, at very minimal retention time, cocurrent contact gases-oilseeds, to effect the efficient vaporization and removal of the moisture to the desired level, dependent on the particular material. The process is conducted on a continuous basis, utilizing the naturally occurring material without denaturation of the protein content. A consequential advantage and benefit of this drying process is the cleaning of the oil and protein bearing naturally occurring seeds, beans, as mentioned heretofore, prior to the drying method, to separate undesirable materials, such as stems, sticks, leaves, dirt, dust, dockage, from the whole seeds, beans, as received, in specially designed attendant equipment as an integral portion of the process.，下面是Method of and means for flash drying naturally occurring oilseeds专利的具体信息内容。

权利要求

2. Method of seed preparation to control moisture and remove extraneous material, which comprises moving a stream of the seeds to be treated downwardly through a tubular cleaning passageway, driving a stream of air upwardly through said passageway to clean the seeds, creating a stream of hot gases of combustion, conducting said stream of hot gases vertically through a tubular flash dryer and introducing said cleaned seeds into the stream of hot gases prior to the entry of said hot gases into the dryer and centrifugally separating the seeds from the hot gases.

3. Method of treating seeds to remove moisture and dirt which comprises subjecting a confined stream of downwardly flowing untreated seeds to an upward current of dry air to separate and remove moisture and dirt, creating a stream of hot gases, driving said stream of hot gases upwardly through a flash dryer, introducing said downwardly flowing stream of seeds into said last named stream of hot gases at a temperature of from 285* F. to 610* F. for a period of from 1 to 8 seconds subjecting said stream of gases and seeds to centrifugal separation and recovering said treated seeds.

4. The method of claim 3 wherein the stream of hot gases is the product of a gas burner and wherein a portion of the stream of heated gases, after separation from the seeds, is returned to said gas burner.

5. Method of treating seeds to remove extraneous solids and moisture which comprises setting up a downflowing stream of untreated seeds, driving a stream of heated air upward through said stream of seeds to remove moisture and extraneous solids, creating a stream of hot air and products of combustion at a temperature of from 285* F. to 610* F., delivering said stream of downflowing seeds after removal of moisture and external solids into an upwardly moving stream of hot air and products of combustion for a period of from 1.0 to 12.0 seconds and centrifugally separating the hot gases and treated seeds.

6. Means for cleaning and drying seeds comprising the combination of a countercurrent cleaning unit having a seed supplying inlet at its upper end and a seed outlet at its lower end, a hot air inlet adjacent its lower end and an exhaust air outlet at its upper end, a surge tank for seeds communicating with said lower end of the cleaning unit to receive discharge of seeds from said countercurrent cleaning unit, a hot air furnace, means for creating a flow of heated air from said furnace, a seed feeder for delivering seeds at a predetermined rate from the surge tank into said flow of heated air from said furnace, a flash dryer maintained at an internal temperature of 285* F. to 610* F., a cyclone separator, said flash dryer delivering the flow of heated air from the furnace and entrained seeds to the inlet of said cyclone separator, means for withdrawing the seeds from the separator and a pump having its inlet connected to the exhaust outlet of said separator and its discharge connected to the hot air inlet at the lower end of the countercurrent cleaning unit.
