摘要： The invention discloses method and system of drying renewable sources of energy and raw material. The drying process is carried out under partial vacuum conditions and at lower temperatures than conventional dryers. The temperature to dry the material and the rate of water removal are controlled by regulating the degree of vacuum and the intensity of heat input. A method for drying material to moisture content below 10% by weight, comprises introducing into an ejector a stream with a pressure above ambient pressure, creating partial vacuum in a drying chamber through the secondary nozzle of the ejector when the stream enters the ejector and provides the motive pressure to the primary nozzle of the ejector, said drying chamber having an inlet into which a wet material is introduced and an outlet for taking out the dried material after the drying treatment, drying the wet material using low temperature waste heat.

摘要： A papermaking process including the steps of forming a wet paper web on a papermaking machine, pulling vacuum through the web to remove water from the web and thereby generate discharge air, and diverting at least a portion of the discharge air through a control loop to a hot air drying system within the papermaking process to aid in drying the web, wherein the vacuum is generated by centrifugal blowers.

摘要： This invention was designed to condense, separate and collect volatile compounds from the vapor steam as they exit the dehydrator. Bulk condensate is allowed to accumulate and separate in a separator vessel under vacuum. The undesirable water phase condensate is periodically drained into a water vessel, which is also held under vacuum instead of atmospheric pressure to avoid agitation and mixing of the contents of the separator vessel arising from purging the separator vessel to atmosphere. The separated and desirable oily condensates can then be easily recovered from the separator vessel.

摘要： An apparatus and method for providing a simpler and more robust mechanism for transporting materials to be dried through a vacuum microwave chamber in rotating containers. The apparatus (20) has a vacuum chamber (22), an input end (26) to introduce a container (24) into the chamber, and a discharge end (28) to remove the container. The container has spur gear teeth (60) extending along its outer circumferential surface. The apparatus has a single roller (42) having spur gear teeth (46) extending along its outer circumferential surface. The spur gear teeth of the roller mesh with the spur gear teeth of the container such that rotation of the roller about its longitudinal axis rotates the container. The apparatus also includes means for holding the container on the roller, means for moving the container through the chamber, a microwave generator 76 arranged for transmission of microwave radiation from the generator into the chamber, and means for reducing pressure inside the chamber.
