The present disclosure provides a bottom drying type sludge drying device, comprising: a housing in which a curved-face partition is provided for separating space in the housing into first and second drying chambers; a feed gate and an outlet provided on an upper portion of the first drying chamber, and a discharge gate provided on the circumferential wall of the first drying chamber. An inlet is provided on a side wall or bottom of the second drying chamber. The curved-face partition comprises a depressed area in which a communication opening is formed, and a bridge-shaped element is provided above the communication opening, forming a lateral aperture between the bridge-shaped element and the partition. A sludge stirring assembly is provided in the first drying chamber, which comprises a rotary shaft and a stirring unit fixed on the rotary shaft, and the stirring unit is configured to cut, break and stir the sludge and/or that a front end thereof faces and is close to the lateral aperture, such that the front end scrapes the sludge in or at the communication opening as the stirring unit rotates. The present disclosure further provides a method of drying sludge using a sludge drying device.

This invention in the field of grain drying, along with other particulates, provides an apparatus which dehumidifies air, then heats the air to relative low drying temperatures (95-160 Deg. F.), provides the dehumidified, heated air as process air to a system which uses the airflow as a transport method to fluidize the particulate matter and move the mixed process air and particles through a process column for drying. Once a particle reaches a designed moisture level, its mass will have been reduced, and that effect plus the velocity of the process air in the column will float the dried particle up and out of the column for further handling.

A method for drying a component interior of a component can be used in a lithographic process chain. The method includes a first drying step, in which simultaneously heated air is admitted into a component interior through an inlet, and the heated air is sucked out of the component interior through an outlet. The method also includes a succeeding second drying step, in which the inlet for the heated air is closed and the air is sucked out of the component interior, resulting in a reduced pressure is generated in the component interior.

Potentially off-grid grain conditioners that can be operably connected to an aeration grain bin or silo to blow heated air through the crop to dry the crop or to blow ambient temperature air through the crop to cool it are disclosed. A fan is powered by a motor that may be mounted inside the air stream to allow the heat from the motor to be collected and forced into the airstream that is blown into the grain bin. The engine exhaust may be routed through an air exchanger to remove heat from the exhaust and direct heat into the grain bin, or the exhaust may be put into the atmosphere without capturing any of the heat, which allows the fan to operate in a cooling mode. The motor may be mounted inline or mounted to the side for a centrifugal aeration fan.

Method for the preparation of dried polymer pellets in a facility having a dryer with a first chamber and a mechanical agitator, and the facility further having a degassing silo with a second chamber, the method includes the steps of guiding a drying gas flow made from or containing a first gas mixture for drying wet polymer pellets into the first chamber, transferring the dried polymer pellets into the second chamber, guiding a second gas mixture for degassing the dried polymer pellets into the second chamber thereby transforming the second gas mixture into a third gas mixture and guiding a portion of the third gas mixture into the first chamber; and process for manufacturing LDPE pellets.

The invention relates to a method of manufacturing a component (21) from metal-containing powder. A paste is prepared by mixing at least a powder (11) comprising metal, a binder (12) in an amount of 2 to 8 weight % of the paste (10), and liquid (13), such as water, in an amount of 5 to 25 weight % of the paste (10). The paste is transferred to an extruder (31), and the paste is extruded into a green body (20) by using an extrusion pressure (P) of more than 50 bar. Then the green body (20) is dried and sintered or oxidized to obtain the final component.

The invention relates to a method for drying a quantity of moulding powder, such as starch, used in a confectionery moulding process to a desired moisture content. The quantity of moulding powder is divided into at least a first fraction and a second fraction, wherein the first fraction is dried to a first moisture content and the second fraction is dried to or remains at a second moisture content, the first moisture content being lower than the second moisture content, wherein at least a portion of the dried first fraction and at least a portion of the second fraction are combined in order to obtain a resulting moulding powder having the desired moisture content. Further, the invention relates to a system for carrying out the method.
