A separator system (1) and method for separating a mixture including said one or more liquids or semi-liquids and a loose, solid material substantially into liquid and solid phases. The system includes the components of: a compression separator (100) for separating the liquid from the solid material by compression; a vacuum supply (200) for generating suction to draw mixture into the separator via a feed line. The liquids are captured in a collection tank (301) and the solids in a hopper (320).

Provided is a washing device that washes a filter of an extraction device with a fluid, the extraction device including an extraction tank for storing an extraction material, a lid body supported openably and closably at a lower portion of the extraction tank, and the filter which is provided on the lid body, and on which the extraction material is placed, the washing device including, a tube body which is disposed at a fixed position with respect to the extraction tank, and through which the fluid passes, and an ejection port provided on the tube body and injecting the fluid toward the filter when the lid body is in an open state.

A non-powered drain pump screen device is disposed in a river, a stream, a waterway, or a place in which a significant amount soil is carried by a water flow. Upper and lower impellers are provided with upper and lower blades. The lower blades prevent reentry of impurities while rotating due to resistance to a flow of fluid in a non-powered manner. The upper impellers are rotated in a non-powered manner, so that the upper blades filter impurities. The non-powered drain pump screen device is disposed in a waterway to remove impurities at low maintenance costs.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.

A food processing apparatus includes a pressure vessel defining a compartment having an inlet end for receiving food product and an outlet end for discharging food product, an open-top screen mounted within the compartment and movable relative to the compartment between a first position, for food processing, and a second position, to facilitate cleaning, a rotatable auger mounted such that at least a portion of the auger is within the screen, the auger being operable to advance food product within the compartment from the inlet end of the pressure vessel toward the outlet end, and a transfer mechanism including a conduit in communication with the compartment, a fluid discharge positioned substantially within the conduit, and a pressurized fluid source in communication with the fluid discharge and operable to propel a fluid through the fluid discharge to move food product through the conduit.

A rake system and method may include a framework, a chain, an elongated rail, a support arm, and an engagement feature. The elongated rail may be pivotably connected to the framework. The support arm may be connected to the elongated rail at a first point and may be pivotably connected to the framework at a second point. The engagement feature may be connected to the support arm and may be configured to engage the chain. The rake system may be configured to discard debris.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to regenerating the efficiency of filters for removing microfibers from washing machine waste water, as well as waste from other appliances and other sources of effluent with entrained microplastics. A separator is therefore provided for separating microplastics from waste water comprising a chamber with an inlet and an outlet, at least one sieve structure forming a permeable barrier between the inlet and the outlet and a wash apparatus for washing the sieve structure.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to filtering microfibers from the waste water from washing machines as well as waste from other appliances and other sources of effluent with entrained microplastics or other microp-ollutants. A separator is provided for separating microplastics from effluent comprising; a chamber including at least one sieve structure, a shroud that acts as a vortex finder and a baffle coaxial with the shroud and projecting upwards from the lower end of the chamber, wherein the shroud has a circular lower rim and the baffle has a circular upper rim, wherein the radius of the lower rim of the shroud is greater than the radius of the upper rim of the baffle.

A filter apparatus includes a filter, such as a cartridge, positioned within a housing. The filter apparatus has multiple ports and valves, so as to allow a user to easily switch between a filtration mode of filtering fluids and a maintenance mode of cleaning the filter. The filter can have a filter substrate in a housing and after filtrate builds up on the substrate, the substrate can be cleaned by directing a spray of fluid, such as from a ring of nozzles at the top of the housing, onto the substrate. A maintenance port can be provided to drain the debris washed from the substrate. The filter can switch between a backwash mode and a filtration mode.
