A sheet manufacturing apparatus that shortens the time until the apparatus stops is provided. The sheet manufacturing apparatus has a sieve unit having at least part of material defibrated in a defibration process introduced thereto, moving at a first speed, and passing defibrated material through multiple openings disposed in the main section thereof; and a forming unit forming a sheet using precipitate that past through the openings of the sieve unit; the sheet manufacturing apparatus stopping the sieve unit with defibrated material that was introduced stored inside the sieve unit when production by the sheet manufacturing apparatus stops.

A classifying device may be used to classify a granular material flow. The classifying device may comprise a first inlet that allows a first material flow into the classifying device, a second inlet that allows a second material flow into the classifying device, a static classifier, and a dynamic classifier. The static classifier may be positioned such that the static classifier at least partially surrounds the dynamic classifier. The classifying device may comprise a distributing device that is designed in such a manner that it supplies the material flow of the first inlet to the static classifier and the material flow of the second inlet to the dynamic classifier.

A device and method for cleaning flowers and buds of plants of leaves and plant matter and particulate is provided. The buds are cleaned within a rotating drum having openings in a circular sidewall which rotates adjacent jets emitting gas. Freezing of the plant material and concurrent impacts from ice crystals formed by emitting gas, cleans the buds and flowers of unwanted plant material and particulate.

A media sifter is provided that is operable to separate cleaning media from casings. The sifter has components configured to selectively prevent rotation and allow rotation of a sifting drum rotatably mounted in a housing. The housing has both a cover and a media collection base.

A technology for material separation is provided. The technology enables an output of a first material from a rotary lifter. The technology enables a direction of a fluid stream onto the first material in flight based on the output of the first material such that the first material is separated into at least a second material and a third material. The technology enables a conveyance of the second material away from the rotary lifter. The technology enables a removal of the third material via a vacuum port.
