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.

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.

A solid feces treatment apparatus includes a dehydrator extracting a liquid component from first solid feces to produce second solid feces, a dryer evaporating a liquid component of the second solid feces to produce third solid feces, and a combustor burning the third solid feces, wherein the second solid feces have a solid content of about 25% to about 30%, and the third solid feces have a solid content greater than or equal to about 90% and less than about 100%.

The present invention relates to a new device, a system and a method for both cooking and drying or removing the water phase from material. The device of the present invention has a large area for heat exchange and scrapers which stir the material in the container rather than transferring it around in circles.

The inventive concept relates to a sludge drying apparatus, and more particularly to a sludge drying apparatus that may improve an efficiency of drying sludge that is sewage deposit residues and simplify a drying process.

A screw conveyor (90, 91, 92) for a drying apparatus (1) or a fermentation system is disclosed. The screw conveyor includes a helical element (11) having a longitudinal axis (x) and including a primary spiral (12) and a secondary spiral (13) mounted on the primary spiral and rotatable with respect to the primary spiral around the longitudinal axis; and a set of elongated members (20) spanning the primary and secondary spirals.

The present invention relates to a new device and a way to assemble such a device for both cooking and drying organic material in the process of making meal. The device of the present invention has a large area for heat exchange and scrapers which stir the material in the container rather than transferring it around in circles. The method of assembling the device allows an accurate and convenient assembly so that the scrapers thoroughly scrape all inner surfaces of the device.
