Vertical pressure plate filter

Oil filtersplay a very important role in the production cycle. Both edible and technical oils need to be cleaned at different stages of production. Vegetable oils from crops such as sunflower, flax, soybean, rapeseed, cotton, corn and others require careful repeated filtration.

The classic vertical oil filter looks like a large elongated vessel with a hinged lid and consists of a filter housing, internal plate filters, a lid lifter and an automatic drain device. The cover is mounted on a movable rod, and after tightening with bolts, it ensures complete tightness of the filter. A jack is provided to lift the cover. The design is also equipped with a rotating bracket for moving the cover to the side. In addition to oils, such a filter can also be used to clean other substances that are not aggressive to carbon steel.

Appointment

The vertical pressure plate filter is designed for the purification of edible and technical vegetable oils at various stages of their production (primary purification, winterization, bleaching, hydrogenation), as well as for the purification of other liquids that are not aggressive towards carbon steel.

Raw materials: edible and technical vegetable oil.

Products: purified vegetable oils from crops such as sunflower, flax, soybeans, rapeseed, cotton, corn.

Characteristic

• Design of filter elements. The main filter elements of a vertical pressure filter are internal vertical steel plates. Each filter plate is composed of 5-layer filter mesh (2-layer filter mesh, 2-layer support mesh and middle support frame). The cell size and filtration accuracy depend on the materials that need to be processed.
• The use of steel ensures long-term operation and excellent filtration results.
• The filter tank vessel can also be made of stainless steel. The body is opaque, but you can check the condition of the oil using three special plexiglass lights, which are built into the inlet and outlet pipelines.

The principle of operation

One filtration cycle lasts approximately 2 – 3 hours and consists of 6 steps. The steps follow each other according to the program and are blocked, i.e. each subsequent step can begin only after the signal about the end of the previous step.

• Stage 1 – filling the filter – the filter is filled with oil to the maximum level using a pump;
• Stage 2 - washing the impurities contained in the oil onto the filter plates - using a pump, the oil circulates between the mixing tank and the filter until the filter cake formed by large and small cake settles on the permeable mesh plates;
• Stage 3 - oil filtration - oil constantly enters the filter using a pump and is filtered through the resulting filter cake, the thickness of which is constantly increasing, which leads to an increase in resistance to oil flow and an increase in pressure inside the filter;
• Stage 4 – oil displacement – the oil supply to the filter stops, the oil is pushed out of the filter by the counter pressure of the gaseous medium;
• Stage 5 – drying of the filter cake – the filter cake is dried with a stream of compressed air through the filter plates;
• Stage 6 - shaking the filter press cake - under the influence of the built-in vibrator, the filter cake is removed from the plates and removed through the open valve from the filter housing.

Advantages

• No filter cloth or filter paper is used, instead high-quality and durable stainless steel mesh is used, which greatly reduces the cost of filter elements;
• Automated sludge discharge - vibrating cake (vibration discharge), saving labor costs;
• Easy to maintain;
• No contact of oil with air - acid and peroxide numbers do not increase;
• Minimal oil loss;
• Environmentally friendly production, the process takes place in a protected housing;
• Food quality standard (the vessel body is available entirely from stainless steel).
• 2 year warranty.
