Filter Expression Drier

Alpha Process Engineers offers a filter expression drier (FED). It is a Nutsche type filter designed to separate solids from liquids. It is totally enclosed and is normally operated under inert gas pressure or under vacuum. Additionally, the equipment is fitted with a spreader mechanism which effi-ciently agitates the slurry during cake washing, smoothens and expresses (squeezes) the cake during filtration and assists in the automatic discharge of the cake. Where the FED is operated in the drier mode, the spreader system again efficiently agitates the wet cake to improve upon the heat transfer to achieve quicker drying times. The FED gives ex-cellent separating qualities with good medium filtration products, optimum filtration times and if used only for filtration applications, the equipment gives lowest residual moisture in the cake when compared with other similar systems. Applications include the manufacture of various chemicals (include toxic), agricultural chemicals (including insecticides, pesticides), dyes and intermediates, pharmaceutical products, food products, etc.
