Horizontal pressure plate filter

Oil filters play 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 horizontal oil filter looks like a large elongated horizontal reservoir with a removable lid. The housing and cover connector are sealed with a gasket, which is compressed when the bayonet ring is rotated using two hydraulic cylinder locks. The lid is also removed from the body using a hydraulic cylinder.

The filter consists of a housing, internal plate filters, a lid lifter and an automatic drain device. The filter elements are removable vertical filter plates, tightened from above with two threaded ties into a bag. The filter plates are equipped with fittings at the bottom to drain the filtrate into the collecting manifold and further into the pipeline.

Filter plates are made of stainless steel. It is also possible to make the filter tank housing 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.

Appointment

Horizontal pressure plate filters are designed for purification of technical and edible vegetable oils at different stages of their processing:

• primary purification of vegetable oils;
• in vegetable oil winterization/freezing lines;
• in vegetable oil bleaching lines;
• selection of catalyst in lard production plants.

Can also be used to clean other liquids that are not aggressive towards carbon steel. Filters have a wide range of models.

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 horizontal pressure filter are internal horizontal 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.
• For visual monitoring of the flow and purity of the filtrate, the filter is equipped with inspection lights, which are installed on 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

• Highly efficient, energy-saving equipment;
• The filtering process can be fully automated;
• 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;
• The filtered sediment (cake) can be washed, dried and used for further processing, generating additional income;
• Environmentally friendly production, the process takes place in a protected housing;
• Food quality standard (the vessel body can be made entirely from stainless steel);
• 2 year warranty.

We offer oil and fat enterprises plants for processing, purification and filtration with a two-year warranty and post-warranty service. Cooperation with us – this is reliability, efficiency and long-term partnership!
