   Auger/agitator fillers: designed to fill dry mixes, such as flour and sugar. [1] The fillers have a hopper shaped like a cone that holds the mix and puts it in a pouch using an auger conveyor that is controlled by the agitator. The mix is filled in a pouch that is made of paper or poly that is formed in a collar and the pouch gets sealed by a ...

5. Vacuum filler - Wikipedia

   Hopper vacuum systems The additional creation of a hopper vacuum is a variation of the vacuum filler concept. The vacuum system is enhanced with an additional vacuum pump, specially designed for the hopper. The hopper is closed and is connected to an upstream reservoir. The vacuum present in the hopper allows filling product to be drawn into ...

6. Trickle valve - Wikipedia

7. Rotary vacuum-drum filter - Wikipedia

   en.wikipedia.org/wiki/Rotary_vacuum-drum_filter

   A Rotary Vacuum Filter Drum consists of a cylindrical filter membrane that is partly sub-merged in a slurry to be filtered. The inside of the drum is held lower than the ambient pressure. As the drum rotates through the slurry, the liquid is sucked through the membrane, leaving solids to cake on the membrane surface while the drum is submerged.
