Hydroextractor
Hydroextractors are machines which are used in textile processing industry. These are mainly centrifuges. The wet material is placed in the extractor, which has a wall of perforated metal, generally stainless steel. the internal drum rotates at high speed thus throwing out the water contained in it. The use of hydroextractor significantly reduces the energy required to dry any material. Hydro Extractors usually work on centrifugal force creating a high Gravitational force enhancing water extraction.
