HFU640GF100J High Flow Filter for Food and Beverage UF Pretreatment
This guide covers the HFU640GF100J high flow filterfor food and beverage, designed for sanitary liquid filtration and upstream protection of ultrafiltration systems in food production lines. A liquid filterwith food-contact compliant materials removes suspended particles, pulp fibers and foreign debris to safeguard downstream UF membranes for beverage, dairy and food processing. This sanitary filter cartridge matches 4.5 Inch Diameter Filter Cartridge for Ultrafiltration Pre-treatment, supporting large flow rates while complying with food hygiene standards for continuous production.
The HFU640GF100J high flow filter for food and beverage is a sanitary high-throughput filter cartridge, specially developed for food, beverage, dairy and edible processing liquid filtration, widely used as the pretreatment security filter before ultrafiltration equipment. Different from industrial general-purpose filter cartridges, this product strictly controls raw material safety, migration risk and media shedding, all wetted materials meet food contact requirements, and it can effectively intercept pulp, fiber, sediment, colloid and tiny solid impurities in food liquid, preventing these contaminants from scratching, fouling and blocking expensive ultrafiltration membrane elements.
Food and beverage production has strict requirements for filtration stability. Juice, sugar syrup, dairy raw liquid, brewing liquid and purified water for food preparation all need stable, low-risk filtration. Once the filter media sheds fibers or releases harmful substances, it will lead to product batch rejection and hygiene non-compliance. The HFU640GF100J 60-inch high flow filter cartridge adopts food-grade glass fiber filter media, polypropylene inner core and certified food-grade sealing components, which balances high dirt holding capacity, large flow rate and sanitary safety.
For food and beverage pretreatment system design, staged filtration is a mature scheme. If the raw material liquid contains a large amount of coarse impurities, users can configure High Flow Rate Filter Cartridge for Ultrafiltration Pre-treatment as the primary filter. For projects that require strict particle removal efficiency to guarantee finished product clarity, Absolute Micron Rating High Flow Filter for UF Pre-treatment can be selected for fine polishing.
When raw liquid contains a high concentration of fruit pulp and solid residues, many food factories adopt two-stage filtration: the first stage uses coarse precision elements such as 100 Micron High Flow Filter Cartridge for Ultrafiltration Pre-treatment to capture large pulp and particles, reduce the pollutant load of the secondary filter. The second stage uses fine precision filter elements including 5 Micron High Flow Filter Cartridge for Ultrafiltration Pre-treatment to remove fine suspended matter, so that the filtrate can enter the ultrafiltration unit safely and steadily.
The matched sanitary filter housing is usually made of polished 304 or 316L stainless steel, with no dead angle design, which is convenient for CIP online cleaning. The end caps and sealing gaskets are food-grade EPDM or silicone, which will not produce odor, swelling or substance precipitation when contacting sugar liquid, fruit juice, weak acid beverage and other food media. The outer-to-inner radial pleated structure of the filter cartridge provides a huge effective filtration area, reduces the liquid flow velocity, lowers the pressure drop, and extends the service cycle in food continuous production lines.
The high flow filter for food and beverage follows the radial outer-in, inner-out filtration principle, and the whole flow path is optimized for sanitary requirements. Unfiltered food liquid enters the sanitary filter housing through the inlet, fills the outer cavity of the vessel, and then passes through the pleated food-grade filter medium from the outer surface of the HFU640GF100J cartridge. Impurities such as pulp, fiber, sediment, protein aggregates and tiny particles are trapped on the surface and inside the depth structure of the filter medium. The clarified food liquid flows into the inner support core of the filter cartridge and flows out through the manifold to the ultrafiltration pretreatment unit.
Depth filtration is the core interception mechanism of this product. The multi-layer gradient pore structure of the glass fiber medium can capture particles of different sizes step by step, and it has excellent adsorption capacity for colloidal impurities in fruit juice and dairy liquid. The differential pressure monitoring device installed at the inlet and outlet tracks the pollution loading status of the filter cartridge in real time. As intercepted pulp and solid impurities accumulate, the differential pressure rises gradually. When the preset alarm value is reached, the operator needs to stop the feeding, empty the liquid inside the housing, and replace the filter cartridge.
Sanitary design details are very important for food-grade filtration. The internal flow channel has no dead corners, to avoid residual liquid breeding bacteria. The filter housing is equipped with vent and drain ports, which can cooperate with CIP cleaning to flush residual sugar liquid and organic matter. It is important to clarify that this high flow filter is used for solid-liquid separation and pretreatment protection of ultrafiltration equipment. It cannot remove dissolved sugar, small molecular flavor substances or dissolved ions. The separation, concentration and clarification of these soluble components rely on the downstream ultrafiltration membrane system.
Material compatibility is another key point. The selected filter media and sealing materials must not react with the food liquid, and cannot release peculiar smell or soluble substances. All raw materials have food contact certification, which can effectively avoid secondary pollution to the food liquid and ensure the safety of finished food and beverage products.

The above parameters are calibrated under clean water test. The actual pressure drop, service life and filtration effect are affected by the solid content, viscosity, temperature and pH of the on-site food liquid. For high-viscosity liquids such as concentrated syrup, it is recommended to reduce the flow rate properly to avoid excessive pressure drop and premature blockage of the filter cartridge.
All high flow filters for food and beverage are manufactured and inspected under ISO9001 quality management system. Every batch of raw materials including filter media, support core and sealing gaskets is tested for food contact safety, and material certificates are provided. The pleating process is controlled accurately to ensure uniform pleat density, avoid local thinning and fiber shedding of the filter medium.
Each finished HFU640GF100J cartridge will pass the bubble point integrity test before leaving the factory to confirm there is no bypass leakage. The matched sanitary stainless steel housing is welded by certified welders, with full weld seam inspection and hydrostatic pressure test at 1.5 times the design pressure. The internal manifold plate is CNC machined to ensure high flatness, so that each filter cartridge can be tightly sealed after installation, preventing unfiltered liquid from bypassing and entering the ultrafiltration membrane system.
The production workshop is cleaned and controlled to reduce dust and foreign matter pollution. The finished products are packed in food-grade clean packaging bags. We can provide material safety data sheets, food contact test reports and factory inspection documents. The operation manual clearly marks the applicable medium, temperature limit and cleaning suggestions, to help customers standardize operation and prevent hygiene risks caused by improper use. Complete production batch records are retained for traceability.
