Equipment Description
Filters of the brand ГНП (horizontal pressure leaf) are designed for purification of technical and edible oils on the different stages of processing:
– primary purification of vegetable oils;
– in lines of winterization of vegetable oils;
– in lines of bleaching of vegetable oils;
– separation of catalyst in the lines generating hydrogenated fat.
Horizontal filters can be also used for filtration of other substances (non-aggressive to carbon steel).
Operating principle
The horizontal filter is a horizontal vessel with a removable cover. Tightness of the tank is provided by means of a bayonet shutter (the cover is pressed by a ring by means of two hydraulic cylinders of the shutter). Also the hydraulic cylinder helps to take away a cover of the body.
Inside the horizontal body of the filter there are filter elements – vertical filter plates installed. Filter plates consist of 5 layers of steel mesh: 1 layer of frame mesh, 2 layers of backing mesh and 2 layers of filter mesh. Depending on the process on which the filter is installed, the filter mesh itself differs in weaving and material of manufacture.
Pressure filters have a number of advantages over outdated frame (belting-cloth) filters:
– filtering cloth is not used, instead of it high quality durable stainless steel mesh is used;
– automatic sediment discharge (vibrodischarge);
– simple service;
– no contact of oil with air means no icnrease in acid and peroxide index;
– minimal oil losses.
