The disclosure relates a roll press arrangement, in which a rotatable side plate is supported against axial ends of press rolls to delimit a nip between press rolls and to prevent feedstock from escaping therefrom. Moreover, a clearance is arranged between the side plate and the axial ends of the press rolls so as to provide a drainage route for liquid dewatered from the fibrous granular feedstock. A press roll apparatus and a method for dewatering fibrous granular feedstock are also disclosed.

A juicer insert for inserting into a preparation vessel, which juicer insert includes at least one rotatable tool holder, including at least one adapter element and at least one juicer tool. The transmission of rotational force the adapter element is configured at least indirectly couplable with the tool holder. The juicer tool is connected to the adapter element, so that a rotation of the adapter element causes a rotation of the juicer tool.

A torque reaction arrangement (50) for twin press-roll pulp washers comprises a first torque reaction arm (10), a second torque reaction arm (20), a first link (19), and a second link (29). The links are provided between the ends of a respective torque reaction arm and a point close to the mounting to a respective stator of the other torque reaction arm. The torque reaction arms are rigidly mounted to a respective stator of a respective press roll motor. A twin press-roll pulp washer with such a torque reaction arrangement is also disclosed.

A portable roller compactor for compacting waste located in a container, which is open on the top, has a frame-like basic structure and an articulated arm, one end of which is supported by the basic structure, and the other, free end of which supports a roller compactor that essentially can be rotated about a horizontal axis of rotation. The articulated arm of the roller compactor is pivotably attached to a sliding carriage, which is mounted on the frame-like base structure and can be moved in a longitudinal direction.

The problem of deck channel rewetting that occurs when a drainage chamber in a roll upwardly approaches a horizontal line extending past the horizontal diameter of the roll is solved by using a comb plate comprising at least one comb tooth engaging the perforated plate and extending through a deck channel to a drainage channel such that the at least one comb tooth has a slope configured to direct a slurry suspension from the perforated plate into the drainage channel.

An apparatus and system for extracting essential oil from plant material, and in particular, cannabis plant material, is described. The apparatus has top and bottom rollers that apply heat and pressure to the plant material as the plant material passes through the rollers for the extraction of essential oil. The top and bottom rollers are powered by a hand crank or motor, and the top and bottom rollers are heated by heaters regulated by a temperature controller. Also described is a method that uses a combination of heat, pressure, and speed for efficient extraction of high quality essential oil from plant material, and in particular, cannabis plant material.
