    • The present invention relates to fluid bed processors used in various industries for drying, coating, agglomerating, and performing other specific processes on particle materials. The processor is especially useful for processing particles, utilizing a hydro dynamically active layer (HDAL) produced by introducing a high speed gas jet through said particulate material under controlled conditions. The processor is adapted to be implemented in a plurality of different fluid bed applications and results in much more efficient particle processing, and a significant savings in energy consumption. The present invention also relates to a method comprising the steps of introducing particulate material into the processing chamber and passing a high-speed jet gas through a plurality of nozzles located in the base of said processing chamber, thereby producing distinct regions of low pressure so as to create an intense, substantially circulatory pattern of gas circulation into which said particulate material is picked up.

    • A jet spouted fluidised bed drier is described in which the bottom half of the drier chamber comprises a first lower conical part, and the top half of the drier chamber comprises a second upper conical part surrounding a conical grid located near to the top end of the second part. The drier chamber thus comprises two conical parts connected together at their wide ends. The result of this arrangement is that the collision zone becomes a toroid with an essentially triangular cross-sectional shape defined essentially by the conical internal surface of the top part and the conical outer surface of the conical grid. This revised structural arrangement has been found to be able to process materials which either cannot be processed, or cannot be processed efficiently, with known jet spouted fluidised bed driers. Additionally, this revised structural arrangement has been found to be able to process materials more efficiently, and to a lower desired final liquid content values.
    • 描述了喷射流化床式干燥器的喷射器,其中干燥室的下半部分包括第一下部锥形部分,并且干燥器室的上半部分包括围绕位于第二下部锥形部分的顶端附近的圆锥形格栅的第二上部锥形部分 第二部分。 因此,干燥室包括在其宽端连接在一起的两个锥形部分。 这种布置的结果是碰撞区域成为基本上由顶部的锥形内表面和圆锥形格栅的圆锥形外表面确定的基本上三角形横截面形状的环形面。 已经发现这种修改的结构布置能够使用已知的喷射流化床式干燥器处理不能被加工或不能有效地加工的材料。 此外,已经发现,这种修改的结构布置能够更有效地处理材料,并且能够达到较低的期望的最终液体含量值。

    • A spout-fluid bed drying system and process is comprised of a spout-fluid bed dryer having a conical shaped lower section provided with a packing of heat exchange particles. A cyclone separator is connected to the top of the dryer with separated particles collected by a receiver connected to the leg of the cyclone. A vapor fan compresses the air-vapor mixture before it goes to the heat recuperator and mixing chamber. A tube-shell type heat exchanger, wherein effluent gases from the vapor fan are preheated with heat exchange with the outcoming high temperature gases. A combustion and incineration chamber wherein a natural gas burner is installed at the top and the high temperature flame is used to incinerate the effluent gases introduced from the annulus channel of the chamber to have the odors and VOCs destroyed. A mixing chamber wherein high temperature stream from the incineration chamber is mixed with low temperature stream from the vapor fan to serve as the drying media with the temperature maintained at around 400.degree. C. A slurry discharge nozzle is disposed below the packing and connected to a slurry container via piping and a slurry pump for releasing slurry to the surface of the particles within the packing. Evaporation of water occurs mostly on the surface of particles by contact with hot drying media. A gas-air mixture is fed to the burner through a feed pipe line wherein fresh air is supplied from an air blower.
