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.

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.

A process and a device for obtaining oil from seeds, wherein at least one of the parameters of moisture, fiber content and oil content of the pressed material is continuously measured and evaluated, thus making it possible to continuously control at least one of the following variables: moisture of the pressed material, speed of the press drive and amount of an extraction agent supplied. The oil yield can be increased, the fluctuations in the oil yield can be reduced and energy can be saved by implementing the device-related and process-related features according to the invention.

The present invention discloses low cost, on-site, efficient, and compact (stationary or mobile) system for continuous (non-batch operation) conversion of waste to usable products such as sources of energy, fertilizer, etc.

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 method for removing liquid from a slurry includes: (i) feeding the slurry into the inlet of a press; (ii) removing liquid from the slurry as the slurry advances through a deliquifying section of the press, thereby producing a pressate stream; (iii) forming a plug of material as the slurry is advanced through a plug formation section of the press; (iv) advancing the plug of material to a discharge section of the press; and (v) removing additional liquid from the plug of material by operating the press so that the pressure in the discharge section of the press is greater than the pressure of the pressate stream by at least 2 psi. The present invention also relates to a method for controlling discharge consistency from a press, without provision of discharge restrictors, by varying the pressure differential between a discharge section of the press and a pressate stream.

A low speed seed oil expeller press with the capability of extracting oil through a new seed compression design that eliminates the need for filtration, and maintains the captured seed oil at a temperature below 130 degrees F. It has a seed preheating capability and controls the pressure and extraction oil temperature by adjustments of the expeller speed, the head volume and the size of the pressed seed exit orifice in the thorn. The seed oil expeller press eliminates seed rotation within the head volume so as to eliminate crushing, grinding or tearing of the seed by a symmetrical knived press head. The seed oil expeller press regulates seed temperature, seed feed rate, seed pressure, seed rotation and extracted seed oil temperature so as to compensate for the seed size, seed hardness and seed oil content.

A method for treating a food product of vegetable origin, including the steps of pushing, by means of a pushing device, the food product within a treatment cavity. This is defined between an internal surface of a fixed hollow body, or stator, and an external surface having conical shape of a rotor, and has an inlet mouth through which the food product of vegetable origin is introduced within the same and an outlet mouth through which the treated vegetable food product exits the cavity. The treatment cavity has a size which decreases going from the inlet mouth to the outlet mouth. It is provided a rotation of the rotor within the stator about a rotation axis. The combination of the rotation and of the pushing that are carried out by the machines produce a partial crushing of the food product of vegetable origin within the treatment cavity.

A device for sludge treatment comprises a supporting frame of an external casing defining a treatment chamber provided with one inlet opening of the sludge to be treated; one discharge opening of the treated sludge; at least one auger element housed within the treatment chamber, and adapted to move the sludge to be treated along a direction of advancement; and filtration means located internally to the treatment chamber and surrounding the auger element; at least one anodic element associated with the auger element, and application means for applying a potential difference between the anodic element and the filtration means, generating an electric field adapted to interact with the sludge to be treated to produce an electro-osmotic process.

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.
