A screw-type separation device 1 includes a casing 10 including an object discharging port and discharging an object A having been dehydrated, and a separated liquid discharging port; a screw shaft provided inside the casing and extending in an extending direction that is a direction from the one end part to the other end part; a first screw blade extending spirally on an outer peripheral surface of the screw shaft; and a second screw blade extending spirally on the outer peripheral surface of the screw shaft such that a predetermined gap is formed with respect to the first screw blade in the extending direction. A groove is formed on an inner peripheral surface of the casing.

This disclosure describes a machine for treating organic waste, comprising a casing which defines an inner treatment chamber for organic waste delimited at least in part by a screening grid, and an inlet opening for waste at one end of the chamber and an outlet opening at an end opposite to the inlet opening; at least one driven shaft installed in the inner chamber and provided with mechanical means for grinding or pressing the introduced organic waste against the screening grid or against at least one wall which delimits the inner treatment chamber; a first motor, having a drive shaft functionally coupled to the driven shaft; a first transmission system configured to transmit to the driven shaft a rotational movement imparted by the first motor to the drive shaft, the first transmission system comprising at least one first support bearing functionally coupled to the drive shaft. A particular feature of the machine according to the present disclosure consists in the fact that the said first transmission system comprises a second self-aligning roller bearing configured to allow an angular misalignment between a longitudinal axis of the driven shaft and a rotation axis of the drive shaft up to a maximum misalignment value such that a free distal end of the driven shaft may fluctuate heightwise inside the inner chamber for treating organic waste.

A method of extracting one or more chemical extracts from a plant product includes mixing at least a first phytochemical-bearing part of a phytochemical plant product with an oil-bearing plant product, producing an oil mixture from the first phytochemical-bearing part and the oil-bearing plant product using a press device, and extracting at least a chemical extract from the oil mixture.

Appliances useful in extracting a liquid from plant material in the preparation beverages and other food products in the home. An appliance may be embodied in the form of a food processing apparatus having a lid with an entry space formed therein, a rotatable element, and one or more food material contacting surfaces surrounding the rotatable element and disposed below the entry space of the lid. The rotatable element and the one or more food material contacting surfaces are each configured and mutually spatially arranged such that in use a food material disposed about the rotatable element is forced against the one or more food material contacting surfaces. Accordingly, the food material is deformed or divided and is caused or allowed to clear the one or more food material contacting surfaces.

An adjustment assembly for adjusting a gap between a restrictor ring and an auger in an industrial food separator is provided. The adjustment assembly includes an electric motor and a mechanical assembly coupling the electric motor to the restrictor ring. The adjustment assembly is configured to translate rotation of a shaft of the electric motor into movement of the restrictor ring to change a width of the gap. A controller coupled to the electric motor. The controller having one or more processing devices, a memory coupled to the one or more processing devices, and storage media. The storage media has instructions stored thereon, the instructions, when executed by the one or more processing devices, cause the one or more processing devices to send commands to the electric motor to move the restrictor ring to change a width of the gap.

A screw conveyor comprises a shaft, a screw flight arranged to extend helically around, and connected to the shaft at the outer circumference of the shaft, and extending in axial direction along at least a portion of the shaft, wherein the screw flight has an outer edge at the outer circumference of the screw flight, and at least one recess for receiving fibrous material is arranged in the outer edge of the screw flight. The screw flight has a cross-sectional profile with a width in the region of the outer circumference of the screw flight greater than the width in the region of the inner circumference of the screw flight. Furthermore, the invention relates to a separator device for dewatering moist masses, including liquid manure residues and/or digestates, as well as a method for additively manufacturing a screw conveyor and a use of a screw conveyor.

Apparatus for pressing and drying a pre-defined amount of waste includes a metal main frame positioned to provide rigid support, and a body mechanically linked to the main frame through a plurality of linkage plates. The apparatus also includes an inlet vertically mounted on the body and a twin screw assembly to press and dehydrate the pre-defined amount of waste. A plurality of mesh screens is rigidly linked to the main frame along the longitudinal axis of the apparatus to remove compressed liquid. The body is also designed to support rotation of the twin screw assembly, and the inlet includes an ingress cross-sectional opening to receive the pre-defined amount of waste.

A method and an apparatus for providing coolants and/or extractants for at least one press, and to a pressing apparatus. The reliability and accuracy of the feed of a coolant and/or extractant to an extraction press that are needed for large-scale industrial use can be achieved by the combination of a storage device, a metering device and a distributing device.
