    System for using substrates to produce substrates in the form of slurry biogas production, where the size of the machine is adapted to the amount of digestible material in the form of household waste or waste from food production sales that is produced in a suitable local area. The slurry is available in a quality that can be used directly in biogas plants and the treatment plants' gas production.

    Description of system and embodiment of the machine.
    By combining known technology where different functions are optimally utilized to achieve the work and the product that is in demand, a machine is designed which: -efficiently distinguishes substrates from rejects. -treats the waste near the collection point to avoid long transports of untreated waste. -easily adapted in size to the collection area -creats a slurry attractive to the market and which in the future may be for sale. - expands the collection area to include packaged food and be more permissive to foreign materials than the current collection system and allow contamination (eg plastic bags in household waste. - provides a slurry that allows it to be directly digested in sewage treatment plants.
    To solve the tasks described by the method above, a screw consisting of an input part (1) is used under a receiving shaft (2). The screw in the feed part has a smooth thread (3) with an equal pitch per revolution and a shaft (4) which tapers conically in the direction of transport. In this way, the above material in the pocket (2) is felled evenly over the entire surface. The material in the previous thread turn plus what is worked in the next thread turn fits in the same and this is repeated round after round.
    After the feed part, the screw changes into a compression part (4) where the shaft (5) continues to be conically tapered at the same time as the outer diameter of the thread conically decreases (6) towards the discharge end (7). The pitch angle (8) from the feed section is maintained. As a result, the threaded gap is continuously reduced towards the discharge part and a compression of the material is obtained. In the thread turn located in the transition between the feed and compression zone (9), the half thread height is cut down to half a turn to facilitate the feed of the material into the compression zone.
    The shaft of the screw terminates with a co-rotating, axially displaceable, spring-loaded abutment (10) which, in addition to determining the resistance to the discharged material and thus the dry content, constitutes a bearing of the screw shaft in the form of a material ring (11). The screw shaft is mounted in a spherical bearing (12) at the feed end. This bearing arrangement means that, due to variations in the size and hardness of the discharged material around the bearing, the shaft has an irregular pulsating movement radially in varying directions (13), which has a positive effect on both forward transport and squeezing of the slurry.
    The screw is driven by a hydraulic or gear motor (14) within the speed range 10 - 80 revolutions per minute, depending on, among other things, the thread diameter and capacity requirements. Current power ranges are 4 to 80 kW.
    The screw is surrounded by a housing, below the input part U / V-shaped (15) and around the compression part cone-shaped (16) following the profile of the screw and with a gap between thread and housing (17) of 5 to 15 mm to allow the above-described pendulum movement.
    The casing is provided with longitudinal grooves in the form of cut-outs (18) or applied profiles (19) in parts where thread and casing meet. The grooves have an edge radial (20) and an edge obliquely inclined (21) as a release in the direction of rotation of the screw. The task of the grooves is partly to guide the material in the longitudinal direction of the screw, partly to facilitate drainage of slurry backwards towards the transport direction and partly to achieve a pulsating processing of the material by varying the space between shaft and casing.
    The casing is provided with drainage holes (22) for the slurry with a diameter of 10 to 20 mm distributed, partly below the U-shaped feed part and partly around the conical compression part with a distance between the holes of 100 to 200 mm.
    The compression part can be provided with nozzles (23) for steam or hot water to partly dilute the slurry and make it more fluid and partly to facilitate squeezing out of liquid with loose, digestible substance from the plant fibers.
    During the feed section and around the compression section, the slurry (24) is collected in a container and the slurry is pumped to a tank for digestion or to a tanker truck for transport to a biogas plant. The reject (25) goes to incineration.

    Claims (1)
    [1]
    A claim Claim 1 A screw consisting of an input part (1) under a receiving pocket (2). The screw in the feed part has a smooth thread (3) with an equal pitch per revolution and a shaft (4) which tapers conically in the direction of transport. In this way, the above material in the pocket (2) is cut evenly over the entire surface. After the feed part, the screw merges into a compression part (5) where the shaft (4) continues to be conically tapered at the same time as the outer diameter of the thread conically decreases (6) towards the discharge end (7). The pitch angle (8) from the feed section is maintained. As a result, the threaded gap is continuously reduced towards the discharge part and a compression of the material is obtained. In the thread turn located in the transition between the feed and compression zone (9), the half thread height is cut down to half a turn to facilitate the feed of the material into the compression zone. The shaft of the screw terminates with a co-rotating, axially displaceable, spring-loaded abutment (10) which, determines the resistance to the discharged material and constitutes a bearing of the screw shaft in the form of a material ring (11). The screw shaft is mounted in a spherical bearing (12) at the feed end. This bearing arrangement means that, depending on variations in the size and hardness of the discharged material around the bearing, the shaft has an irregular pulsating movement radially in varying directions (13). The screw is driven by a hydraulic or gear motor (14) within the speed range 10 - 80 revolutions per minute, depending on, among other things, the thread diameter and capacity requirements. Current power ranges are 4 to 80 kW. The screw is surrounded by a casing, under the input part U / V format (15) and around the compression part cone-shaped (16) following the profile of the screw and with a gap between thread and casing (17) of 5 to 15 mm. The casing is provided with longitudinal grooves in the form of cut-outs (18) or applied profiles (19) in the parts where the thread and casing meet. The grooves have an edge radial (20) and an edge obliquely inclined (21) as a release in the direction of rotation of the screw. The task of the grooves is partly to guide the material in the longitudinal direction of the screw, partly to facilitate drainage of slurry backwards towards the transport direction and partly to achieve a pulsating processing of the material. The casing is provided with drainage holes (22) for the slurry with a diameter of 10 to 20 mm distributed, partly below the U-shaped feed part and partly around the conical compression part with a distance between the holes of 100 to 200 mm. During the feed section and around the compression section, the slurry (24) is collected in a container and the slurry is pumped to a tank for digestion or to a tanker truck for transport to a biogas plant. The reject (25) goes to incineration. Claim 2 Device according to claim 1, wherein the compression part is provided with nozzles (23) for supply of steam or hot water.
