A 20x20 Plate Filter, is a type of filtration equipment used for separating solids from liquids. It is commonly used in industries such as food and beverage processing, pharmaceuticals, chemicals, and winemaking. The "20x20" designation refers to the size of the filter plates used in the filter press.20x20 plate filters are relatively small and are often used for laboratory-scale or small-batch applications. Larger filter presses with larger plates are used for industrial-scale processes where large volumes of liquid need to be filtered. The choice of filter press size and design depends on factors such as the volume of liquid to be processed, the nature of the solids, and the desired level of filtration.

The structure is solid and reliable, ensuring that the filter will not be deformed or damaged in a poor operating environment. The interior is supplemented by a filter material support net, the overall structure is compact, light in weight, and easy to install and disassemble.
4.Filter (Paper Frame) has low resistance, high dust holding capacity, easy installation and disassembly.
The primary effect plate filter is characterized by its low resistance, high dust holding capacity, easy installation, and easy disassembly, and is in the process of UL900 certification. It is widely used in the primary filter section of various industrial, commercial, civil buildings and other ventilation systems.

Plate and frame filters are industrial filtration systems used to separate solids from liquids. They consist of a series of vertical plates and frames with filter media in between. Liquids are pumped through the filter, and solids are trapped by the filter media, forming a cake. The cake is periodically removed, and the filter is ready for the next cycle. Plate and frame filters operate by using pressure to force the liquid through the filter media, allowing solid particles to be captured and separated. The filter media can vary in porosity and material to suit specific applications. These filters are versatile and can handle a wide range of materials and particle sizes, making them a popular choice for many industries.
Plate and frame filters offer several advantages. Firstly, they provide excellent particle removal, ensuring the purity of the filtered liquid. Secondly, they are versatile and can handle a wide range of materials and particle sizes, making them suitable for various applications. Additionally, these filters are relatively easy to maintain and can be scaled up for higher production volumes. They are also known for their cost-effectiveness and efficiency in separating solids from liquids.Another advantage is the ability to customize the filter media and operating conditions to match specific filtration requirements, making plate and frame filters adaptable to different processes and industries.
Filter Plates: These are rigid, flat plates made of materials like stainless steel, plastic, or other corrosion-resistant materials. They have inlet and outlet ports for the liquid.
Filter Frames: These are also made of materials like stainless steel and provide support for the filter plates. They hold the plates together and maintain the alignment.
Filter Media: Placed between the plates, the filter media capture solid particles and form a filter cake. The choice of media depends on the filtration requirements.
Closure Mechanism: This secures the plates and frames together, creating a sealed unit for filtration.
Pump and Pipes: These components facilitate the flow of the liquid through the filter.
Cake Removal System: Some plate and frame filters have mechanisms to remove the filter cake efficiently.
Maintenance of plate and frame filters typically involves several steps. First, the filter plates and frames are disassembled, and the filter media are inspected and replaced if necessary. The equipment is cleaned thoroughly to remove any residual solids and contaminants.Next, the sealing components and gaskets are checked for wear and tear, and they are replaced as needed to maintain a proper seal. The pump and pipes are inspected for any blockages or damage.
Plate and frame filters find extensive use in the food industry for various purposes. They are commonly used to clarify juices, syrups, and oils by removing impurities and suspended solids. In winemaking, these filters help clarify wine and remove yeast cells and particles.Plate and frame filters are also employed in the production of beer, dairy products, and edible oils. Their ability to achieve high levels of purity and clarity makes them indispensable in ensuring food and beverage products meet quality standards.
Yes, plate and frame filters can be automated for continuous operation. Automation can include features like automatic cake discharge, pressure monitoring, and control systems that adjust operating parameters based on filtration conditions.Automation enhances the efficiency and reliability of plate and frame filters, making them suitable for processes that require continuous and consistent filtration, such as in large-scale industrial applications.
Using plate and frame filters can have environmental benefits. Their efficient solid-liquid separation reduces waste generation and minimizes the need for additional processing steps to remove contaminants. This can lead to lower energy consumption and reduced chemical usage in downstream processes.Additionally, some plate and frame filters can be designed for recycling and reusing filtrates, further reducing environmental impact.
