A waste treatment machine is disclosed, having a safety sensor which generates an alarm signal to stop the motor (7) when the requested torque exceeds a certain threshold, but has a gear with a friction transmission belt (8), i.e. not a toothed belt, between a driving pulley (9) and an idle pulley (10) connected to a shaft (6) for squeezing/grinding waste. The friction transmission belt is tightened so as to slip when a nominal maximum torque is exceeded. The protection sensor is configured to detect slippage of the friction transmission belt and to provide in such an event an alarm signal to a control unit that interrupts a normal miming of the motor. The organic waste treatment machine may be a single-worm screw (4) or double-worm screw squeezing machine, or a grinding machine with hammers (13) pivoted at the periphery of a shaft installed in the inner chamber of the machine. A method of controlling such a machine for treating waste is also disclosed.

A screw type separation device includes: a casing that has a separated liquid discharge port on one end part side and has an object discharge port on the other end part side, while the other end part side is positioned lower, in terms of vertical directions, than the one end part side; a screw shaft provided inside the casing; a first screw blade; and a second screw blade that forms a first space between one face and the first screw blade facing the one face and forms a second space between the other face and the first screw blade facing the other face.

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.

The invention relates to a system (1) comprising a feeding device (2) comprising a channel (6) having an inlet (8) and an outlet (10) and a feed screw (12) for conveying biomass material through the channel. The feed screw comprises a screw flight (12b) that extends from a first end (12c) to a second end (12d) and is adapted to form a gas impermeable plug of biomass. The system comprises at least one primary measuring unit (14; 16) adapted to continuously measure a primary variable indicative of the gas permeability of the plug, which primary measuring unit is connected to said feeding device between the first end of the screw flight and the outlet; and a control unit (3) adapted to use said primary variable values to monitor the gas permeability of the plug. The invention also relates to a method for preventing blow back in the above described system.

A conveyance unit mounted to a machine for initial processing of natural raw rubber into aged rubber product, includes: a discharge delivery belt connected with the machine to receive the aged rubber product; a vibration delivery device connected to the discharge delivery belt to selectively delivery the aged rubber product from the discharge delivery belt; a drying and cooling device, comprising an elongated channel body and a circulation system mounted therein, wherein the rubber product is entered from one end of the elongated channel body while being dewatered and left from the other end of the elongated channel body, wherein the circulation system is operated to provide wind inside the elongated channel body for drying and cooling the rubber product; and a cutting device connected to the elongated channel body of the drying and cooling device to cut the dried rubber product into aged product.
