What is the difference between a plate and frame filter, a vertical leaf filter and a centrifugal filter？
Plate and Frame Filter:
Plate and frame filter is a type of filter that consists of a series of frames with filter plates arranged alternately. The frames are typically made of metal or plastic and contain filter media, such as filter cloth or filter paper, which traps the impurities while allowing the clean oil to pass through. The frames are pressed together to create pressure, which forces the oil through the filter media.
Advantages of Plate and frame filter:
Suitable for a wide range of oil types and capacities.
Can achieve high filtration efficiency.
Easy to clean and replace filter media.
Can be used for both small-scale and large-scale oil processing operations.
Vertical Leaf Filter:
Vertical leaf filter, also known as a pressure leaf filter, is a type of filter that uses a series of vertically arranged filter leaves to separate the impurities from the oil. The filter leaves are typically made of metal or plastic and have filter media, such as filter cloth or filter paper, which traps the impurities while allowing the clean oil to pass through. The filter leaves are compressed together to create pressure, which forces the oil through the filter media.
Advantages of Vertical Leaf Filter:
Suitable for large-scale oil processing operations.
Can achieve high filtration efficiency.
Can handle high flow rates and high-pressure operations.
Easy to clean and replace filter media.
Can be used for both pre- and post-filtration in oil refining processes.
Centrifugal Filter:
Centrifugal filter, also known as a centrifuge, is a type of filter that uses centrifugal force to separate the impurities from the oil. The oil is fed into a rotating bowl or drum, and the centrifugal force causes the impurities to settle on the walls of the bowl or drum, while the clean oil is collected and discharged.
Advantages of Centrifugal Filter:
Suitable for small-scale oil processing operations.
Can achieve high filtration efficiency.
Can handle high flow rates and high-speed operations.
Can be used for continuous operation.
Does not require filter media, so no need for regular replacement.
The choice between a plate and frame filter, vertical leaf filter, or centrifugal filter depends on various factors such as the specific oil processing requirements, capacity, budget, and maintenance considerations. Each type of filter has its own advantages and limitations, and it’s important to carefully assess your needs and consult with oil processing experts or equipment manufacturers to determine the most suitable option for your small oil press factory.
