Devices facilitating recovery of polymers are disclosed. A crushing device (25) includes a housing (13) into which a paper diaper (D) containing polymers (P) in a water-absorbed state is thrown, and a crushing member (28) that is accommodated in the housing (13) and crushes the paper diaper (D). A moving speed of the crushing member (28) is 0.1 m/s or less.

A juicer having a juice extracting screw assembly, in which a housing with a juice extracting screw installed in the housing has a simplified interior structure, thereby reducing the production cost of the juicer and easily dispensing juice and residue separately using respective passages.

An apparatus for processing a suspension including organic material and liquid, including a housing including an inlet and an outlet; a container arranged within the housing; a screw including a screw shaft and flights arranged within the container; a space defined between the screw and the container, through which the suspension is longitudinally transportable by a rotation of the screw. Further, the container includes a longitudinally extending first part and a longitudinally extending second part; the first part including a beveled edge the second part including a sharp edge whereby an anti-rotation tooth is generated on the inner surface of the container. A method for processing the suspension is also provided.

The invention relates to a method for extracting oil from seeds or fruits of oilseed plants, comprising a pressing step and a step of separating the oily and solid fractions, wherein at least a part of the seeds or fruit is moistened prior to the pressing step. The invention also relates to a device for implementing said method.

Proposed is a food-waste disposal apparatus, in particular, including a transfer housing; a transfer screw rotatably mounted to an inside of the transfer housing, and transferring food waste, which is introduced into the transfer housing, in a frontward direction of the transfer housing while compressing the food waste; and a gap forming portion provided in a rear end portion of the transfer screw, and forming a wastewater discharging gap between a front surface thereof and a rear cross-section of the transfer housing to discharge wastewater coming out of the food waste. Thus, the gap forming portion is provided outside the transfer housing (i.e., outside the rear end portion) and adjustable forward and backward, thereby not only making it easy to adjust a wastewater discharging gap but also discharging the waste water smoothly as a wastewater outlet is oriented downward.

Provided is a wash press that separates liquids and solids from a waste stream. The wash press includes a tank having a semi-cylindrical shape. The tank has an inlet at a top of the tank for receiving a waste stream, a screen disposed in a portion of a bottom of the tank to permit liquid to pass therethrough, and an outlet for permitting solid materials separated from the liquid to pass therethrough. A rotor extends through the tank for transporting and dewatering the waste material entering the tank. The rotor includes a plurality of helical flights interconnected by paddle members to permit agitating the waste material. The wash press also includes a removable cover that enables the rotor to be lifted vertically, and a removably attached screen to facilitate replacement/repair of the same.

A washing pipe is mounted on a washing guide provided on an outer side of an outer cylinder screen of the screw press and includes a washing pipe body and washing nozzles provided in the washing pipe body and configured to discharge washing liquid flowing from an inside of the washing pipe body toward the outer cylinder screen. A washing pipe swing supporter is configured to support the washing guide to allow the washing pipe to swing between a discharge position and a separation position. The discharge position is a position where the washing pipe is mounted on the washing guide and the washing liquid is discharged from the washing nozzles toward the outer cylinder screen. The separation position is a position where the washing nozzles are farther away from the outer cylinder screen than in a state where the washing pipe is positioned at the discharge position.

Solid waste, for example source separated organics (SSO) or commercial and industrial (C&I) waste or both, are treated by first pressurizing the waste against a screen to produce a solids fraction and a liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is pulverized or milled, for example with a hammer mill, preferably after being diluted. The pulverized or milled waste is separated again to provide a second solids faction and a second liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is primarily inert and can be landfilled, preferably after being washed.
