Disclosed is a piston press of the type used in the field of the dehydration of products to be dehydrated such as sludge from a purification plant. More particularly, it relates to a piston press including a pressing chamber supplied with sludge and able to manage air streams that it generates, and to a method for using such a press. In a preferred mode of embodiment, the piston press includes a pipeline having a water removal branch and arranged so as to remove water extracted during a sludge-pressing operation, and an air circulation branch that can channel the volumes of air circulating in the press during the operation thereof, so as to direct the vitiated air, i.e. air that has been brought into contact with the sludge during the implementation of the press, towards a deodorization system.

The carbonate bonded, press-moulded article is produced by press-moulding a particulate, carbonatable material that contains water and by carbonating the obtained compact with carbon dioxide gas. In order to be able to ensure an optimal compressive strength of the article two types of tests are provided. In the first type of test a sample of the particulate material is compressed with an increasing compaction pressure and when water starts to be expelled from the material as from a particular compaction pressure, the press-moulding step is performed with a compaction pressure which is at least 7 MPa smaller than this compaction pressure. In the second type of test different samples of the particulate material are press-moulded with different compaction pressures and, after having released the compaction pressure, the density of the compact is determined. In case this density decreases instead of increases as from a particular compaction pressure, the press-moulding step is performed with a compaction pressure which is smaller than this particular compaction pressure.

The present invention provides a laminator capable of improving evenness of a pressing force applied from pressure-bonding rolls to a substrate and a film. The laminator includes a first pressure-bonding roll, and a second pressure-bonding roll disposed above the first pressure-bonding roll and configured to be displaceable in a direction toward (a first direction) and a direction away from (a second direction) the first pressure-bonding roll. The laminator further includes a support roll configured to support the first pressure-bonding roll below the first pressure-bonding roll, and a pressure application roll disposed above the second pressure-bonding roll. The pressure application roll is configured to be displaceable in the first direction and the second direction, and is also configured to press the second pressure-bonding roll toward one side where the first pressure-bonding roll is located by being displaced in the first direction. The laminator further includes a driving mechanism configured to displace the pressure application roll in the first direction and the second direction.

Embodiments related to press machines, including presses to extract juice from food matter contained within a cartridge. The cartridge is compressible by the press and juice can be expelled through a cartridge outlet extendible though the press region.

A compression apparatus includes an outer shell; a first plate and second plate, where the first plate and the second plate are located within the outer shell and a face of the first plate opposes a face of the second plate The compression apparatus also includes a compression mechanism which retractably moves the face of the second plate into contact with the face of the first plate. The face of the first plate or the face of the second plate includes a substrate layer, and a coating layer over the substrate layer, where the coating layer includes a plasma-enhanced chemical vapor deposition material.

Disclosed is a method for extracting one or more chemical extracts from a plant product. The chemical extracts are purified and extracted by first separating at least a phytochemical bearing part of a plant product from one or more other portions of the plant product. A carrier oil is then heated at a target temperature to be used as the vehicle for extraction and then mixed with the at least a phytochemical bearing part while the target temperature is maintained. The process may be streamlined by having heating and mixing occur in a press device. The mixed carrier oil and the at least a phytochemical bearing part are then passed through the press device to produce an oil mixture. At least a chemical extract may be extracted from the oil mixture, and in some cases may be further purified by evaporation and/or centrifugation.
