A feeding device is provided for a belt drying installation for dump or sewage sludge material dewatered down to a pasty consistency. In the conveying path of the sludge material, a first roller having transverse grooves that are set back relative to the outer diameter of the roller and a guide device are arranged relative to the outer diameter of the first roller such that when the roller is rotated the sludge material is drawn into the transverse grooves and is shaped to elongated extrudates. The first roller is associated with a comb which has teeth that rigidly engage the transverse grooves and which sweeps the extrudates from the transverse grooves, wherein the tips of the teeth which rigidly engage the transverse grooves define a line of engagement. The tooth tips which rigidly engage the transverse grooves are beveled towards the tooth neck.

An apparatus (10) for producing reshaped plastic granules from a plurality of initial granules (12) with a predetermined shape is disclosed comprising: a feeding unit (20) for continuously receiving a plurality of said initial granules (12), a pressing unit (30) for mechanically reshaping the initial granules, said pressing unit comprising at least two opposite pressing surfaces (32) with a gap (34) therebetween, the width (W) of said gap ranging from 0 mm to 0.5 mm, a receiving chamber (40) for receiving the reshaped final granules (13) from the pressing unit, and a frame (50) for supporting the feeding unit, the pressing unit and the receiving chamber. A method is also provided to produce final granules by mechanically reshaping the initial granule, each final granule having a certain surface-to-volume ratio and a primary thickness of at most 0.7 mm within substantially the entire volume of the final granules.

Disclosed herein are systems, methods, and apparatuses for on-site processing of plant-based waste foods, such as near-end-of-shelf-life produce, into dried compositions that are suitable for human consumption. In particular, there is provided a portable apparatus and methods for on-site processing of plant-based waste food into a dried composition that is suitable for human consumption.

The invention relates to a method for grinding and drying a material or material mixture (M), using a cyclone device (10) which communicates with an outlet line (52) for gas (G) and material (M) processed in the cyclone device (10), wherein at least a portion of the gas (G) and material (M) in the outlet line (52) are returned into a lower opening (14) of the cyclone device (10) for further cyclone treatment. The invention relates also to an apparatus.

The production method includes a drying step of drying a particulate crosslinked hydrogel polymer obtained by polymerizing a monomer, which is a material of a water-absorbent resin, using a heating device to obtain dried particles. The heating device includes: a rotary container that contains the particulate crosslinked hydrogel polymer therein and rotates; and a plurality of heating tubes that are located within the rotary container, extend in an axial direction of the rotary container, and rotate together with the rotary container. A gel temperature of the particulate crosslinked hydrogel polymer to be subjected to the drying step, the gel temperature being measured by a contact thermometer, is not lower than 50° C.

The disclosure provides an example food dehydrator apparatus for treating food waste and methods for use thereof. The apparatus includes: (a) a receptacle having a bottom support, a top support, and a cylindrical sidewall extending therebetween, where the receptacle has an interior cavity, where the top support has a first opening configured to receive the food waste, and where the bottom support has a first opening to release dehydrated food waste, (b) a load door, (c) a shaft rotatably arranged within the receptacle, (d) a gear motor coupled to the shaft, (e) a first plurality of paddles, (f) a second plurality of paddles, where the first and second plurality of paddles are static, (g) a third plurality of paddles, (h) a fourth plurality of paddles, (i) at least one heat source, and (j) a gate coupled to the bottom support of the receptacle.

A dehydrator apparatus for dehydrating biological material. The apparatus includes an external housing, and a vessel supported within said external housing and spanning in a longitudinal direction thereof in elevated relation from a bottom of the housing. A loading inlet feeds into said vessel from outside the housing for admission of biological material. An air intake feeds into the housing to deliver heated air thereto from a hot air source, and air routing components within the external housing guide the heated air into heat exchange relationship with the vessel itself, and also into heating and aerating exposure to contents of said vessel. An agitator is installed in operable relation to the vessel to agitate the material fed thereinto via the material inlet. An exhaust outlet exhausts the heated air from the housing after having heated and aerated the vessel and its contents.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. The organic matter processing apparatus includes a lid assembly that is positioned at the top or head of the processing apparatus and an air treatment system. The lid assembly is operative to open to allow a user to deposit organic matter into the processing apparatus or to remove a removable bucket contained therein. The lid assembly is operative to close and provide an odor containing seal that prevents or substantially mitigates escape of odor. The air treatment system uniformly distributes untreated air through an air treatment chamber to convert the untreated air to treated air, which is exhausted out of the processing apparatus.

The partial or full dehydration of organic or inorganic matter containing water by induction of matter into a vacuum and processing matter through a specially designed acceleration channel is disclosed. The inducted matter accelerates in air from zero speed to sub-sonic speed to reach supersonic speed. As the material transitions the sound barrier, it is subject to acoustic shock waves and an instant negative pressure drop occurs. The sound waves disintegrate, disinfect the material and extract part or all moisture from any organic or inorganic material.
