The invention relates to an evaporation dryer () for drying particles, having&#x2014;a process chamber () with at least one product inlet () for supplying the particles to be dried into the process chamber () and a product outlet () for discharging dried particles from the process chamber (), &#x2014;a heat exchanger () arranged within the process chamber (), &#x2014;having at least one inlet () into the heat exchanger () for pressurized steam as process steam and at least one condensate outlet () from the heat exchanger (), wherein&#x2014;the at least one condensate outlet () is connected to an expansion tank (), wherein at least one pump () is connected to the expansion tank (), and the expanding steam is pumped out of the expansion tank () and supplied to the process steam.

Evaporation dryer and method for operating same

The present invention relates to a device for removing fluids and/or solid substances from a mixture of particle-shaped materials with a container which forms a ring-shaped process chamber with a plurality of cells separated from each other by walls, comprising an inlet cell, intermediate cells and an outlet cell, a feeding installation for conveying the mixture to be treated into the inlet cell of the process chamber, a discharge installation for discharging the mixture treated from the outlet cell of the process chamber, a ventilation installation for feeding in a first fluidisation agent, in particular in the form of overheated vapour, from below into the process chamber through an inflow floor for generating a fluidised bed in the process chamber, a heating installation for preparing the first fluidisation agent in the flow direction before the ventilation installation, swirl impellers for conditioning the flow in the container from the process chamber to the heating installation and which in part also leads to a vapour outlet, and a dust removal installation in the flow path between the process chamber and the heating installation, wherein dust can be guided to the outlet cell via the dust removal installation, wherein in order to support a transportation of the mixture from the inlet cell to the outlet cell and/or a turbulence of the mixture in the process chamber, the inflow floor comprises first unevenness and/or at least at times a second fluidisation agent, in particular in the form of overheated vapour, can be fed at least into the inlet cell essentially parallel to the inflow floor by means of first nozzles, and/or first flow guidance members are provided above the inflow floor and/or second flow guidance members are provided below the inflow floor.

Fluidized-bed vaporisation dryer

A device for removing fluids from particulate materials, including a container having a circular process chamber with a cylindrical external contour, an input device for inputting the materials into the process chamber, a discharge device for discharging the particulate materials freed of the fluid from the process chamber, a feed device for feeding a fluidizing agent from below into the process chamber, and at least one conditioning device for conditioning the fluidization agent in the direction of flow prior to the feed device.

Device and method for removing fluids and/or solids

This invention relates to an appliance () for the removal of fluids and/or solids from a mixture of particulate materials with a container () that constitutes a ring-shaped processing space () with a cylindrical outer contour with devices for the charging and discharging of the particulate material into and out of the processing space () and with a fan device () for supplying a fluidization agent from underneath into the processing space () as well as devices () for the processing of the fluidization agent in the flow direction in front of the fan device, whereby in the processing space (), cells () are formed extending in the vertical direction where one cell constitutes a discharge cell () through which there is no fluidization agent flow from underneath where at the lower end of the discharge cell the discharge device is arranged and where another cell () is provided with a charge device and where the cells () are open at their upper ends in order to facilitate transport of the material to the discharge cell (), whereby above processing space (), there adjoins twist scoops () that are inclined or curved in the flow direction from the charge cell () to the discharge cell (), the outside diameter of which cells is not greater than the outside diameter of processing space () and that are surrounded by an outer jacket () that does not radially protrude over the outer jacket () of processing space ().
