Horizontal pressure leaf filter for vegetable oil

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Pressure filters have a number of advantages over outdated frame (belting-cloth) filters: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.

What type of vegetable oil can be used in the horizontal pressure plate filter?
The horizontal pressure plate filter for vegetable oil can be used to filter various types of vegetable oils such as sunflower oil, soybean oil, rapeseed oil and others.
What is the process of cleaning of filter plates in the horizontal pressure plate filter for vegetable oil cleaned?
The filter plates in the horizontal pressure plate filter for vegetable oil are cleaned by backflushing. The flushing process can be automatic or manual depending on the filter model.
What is the principle of operation of horizontal pressure plate filter for vegetable oil?
The horizontal pressure plate filter for vegetable oil filters the oil by means of filter plates, which remove particles and other impurities from the oil. The oil passes through the filter element by means of a circulation pump and then flows into the tank. The backwash can be used to clean the filter elements.
