An additive manufacturing powder handling system includes a powder container and at least two of: an overflow powder collector system configured to collect overflow additive manufacturing powder from the additive manufacturing printer and pass the overflow additive manufacturing powder into the powder container; a vacuum system configured to receive by vacuum force additive manufacturing powder from an additive manufacturing printer and pass the additive manufacturing powder into the powder container; a sieve system configured to filter the additive manufacturing powder; and a powder container moving apparatus configured to move the powder container between any two of the additive manufacturing printer, the overflow powder collector system, the vacuum system, and the sieve system. The powder container includes a powder container coupling. Each of the overflow powder collector system, the vacuum system, and the sieve system includes at least one coupling element configured to receive the powder container coupling.

Examples relate to a seal assembly comprising a base unit comprising an opening and a sealing surface extending around the opening. The seal assembly further comprises a sensor to detect a distance between the sealing surface of the base unit and a sealing surface of a lid when a fastener is connecting the lid to the base unit.

A dust sequestering assembly for sequestering dust from a particulate food item includes a container that may contain a particulate food item. A sieve is positioned within the container and the sieve may have dust pass therethrough. Thus, the dust is sequestered with respect to the particulate food item.

A separation device includes a separation unit that has a first ejection unit having a first ejection port for depositing a material containing a fiber on a first surface, and a first suction unit having a first suction port for sucking from the first surface toward a second surface so that at least a part thereof overlaps the first ejection port, a second suction unit provided at a position different from the first ejection port and having a second suction port for sucking from the second surface toward the first surface, a detection unit that detects information on foreign matter contained in the material ejected from the first ejection port, an input unit that inputs a detection result of the detection unit, and a control unit that controls a separation condition in the separation unit based on the information input to the input unit.

The present disclosure provides locking false filter sieve. The filter sieve includes: a sieve body and a base movably connected to the sieve body. The sieve body is machined from a metal sheet into a circular body. An upper circular edge is machined on an upper edge of the circular body by rolling upwards. A groove and a lower circular edge are machined on a lower edge of the circular body by rolling downwards. The upper circular edge and the lower circular edge at a junction of the circular body are mated with each other and movably engaged with each other. Bases having different numbers of meshes body may be mounted by disposing a fastener device at the junction of the circular body. With the above structure, a base having a desired number of meshes may be mounted during use. The structure is reasonable, and highly practicable.

Disclosed is a pruning and sieving apparatus, which resolves time-consuming and laborious problems in the existing pruning method of flower plants. The pruning and sieving apparatus includes a hollow body, including two relatively disposed open axial ends; an interior pruning lining attached inside the hollow body, where the interior pruning lining includes a plurality of sidewall pruning holes arranged in a distributed manner; a sieving screen, where the sieving screen includes a plurality of sieving holes arranged in a distributed manner, and is disposed in the interior pruning lining to divide the internal space of the interior pruning lining into a pruning chamber and a collection chamber; and two end caps disposed on the two open axial ends.

A material handling machine includes a substantially cylindrical tub having an inlet and outlet where the tub includes a ring configured internally to the tub. A hopper is used for directing materials entering the inlet and a grate covers the inlet for controlling the amount of material into the tub. An impeller is rotated using a motor for processing material singulated by the impeller and a basket sifts material from the impeller. The impeller is supported by the main spindle such that the at least one impeller and basket are interchangeable depending on the type of material.

The present invention relates to a portable and removable vibration sieving apparatus that sorts plant extract and the like according to size, and more particularly, to a sieving apparatus using motorized vibration that is suitable for sorting plant extracts or other particles.

A food-product handling device includes a sifter unit having a housing defining an open upper side, a mount extending outwardly from the first housing along a first axis, and a lower side opposite the upper side. The sifter unit further has a sifter basket having an interior aligned with and inset within the open upper side. The device further includes a scale assembly having a body defining an upper opening and an opposite lower opening and having an annular weight-sensing unit surrounding the upper opening. The body is positionable on the housing of the sifter unit with the opening in communication with the open upper side of the housing. A hopper is positionable on the weight-sensing unit and defines a lower open end at least partially received within the body when the hopper is positioned on the weight-sensing unit.
