5μm PP Winded Filter Cartridge for Impurity Interception in Canned Food Processing Water
Product Introduction
This 5μm PP winded filter cartridge is a specialized food-grade water purification component engineered exclusively for impurity interception in canned food processing water, tailored to the strict requirements of the canned food industry for clean, impurity-free, and hygienic processing water—a fundamental prerequisite for ensuring the safety, quality and shelf life of canned food products. Crafted from 100% food-grade polypropylene (PP) raw materials that comply with FDA, EU 10/2011, national food safety standards (GB 14881) and canned food production water quality norms, the cartridge adopts advanced high-precision spiral winding technology with a reinforced porous food-grade PP inner core and a uniformly structured 5μm PP wire filter layer. It is dedicated to the efficient physical impurity interception of various processing water used in canned food production, including washing water for raw materials and cans, blanching water, cooling water, and formulation water for sauce and brine. The cartridge thoroughly intercepts insoluble impurities with particle sizes ≥5μm such as suspended solids, sediment, rust particles, plant fiber debris, micro-scale solid contaminants from raw material cleaning, and pipeline scale, through pure physical pore size interception without adding any chemical agents, no dissolution of harmful substances, and no alteration to the physical and chemical indicators of processing water. With perfect compatibility with standard food-grade filter housings for food processing, stable 5μm precision impurity interception performance, and adaptability to the large-flow, continuous and high-pressure production characteristics of canned food plants, this cartridge is a core water purification component for canned food manufacturing enterprises covering meat, fruit, vegetable, seafood and sauce categories. It complies with the strict quality and safety control requirements of the canned food industry, effectively eliminates impurity contamination risks in processing water, prevents quality defects such as turbidity, sediment and abnormal color in canned food products, and lays a solid foundation for the hygienic production and shelf life guarantee of canned food.
Filtration Precision
This filter cartridge features a fixed 5μm absolute filtration precision, calibrated and optimized specifically for the impurity characteristics of canned food processing water and the practical impurity interception needs of canned food production. The 5μm filter layer is manufactured through a precise gap-calibrated winding process with strict quality control, ensuring uniform pore size distribution, no pore size deviation or channeling, and the ability to stably and thoroughly intercept all insoluble solid impurities with particle sizes ≥5μm in processing water. These impurities include sediment and sand particles from raw water sources, rust and scale from water supply pipelines and storage tanks, plant fiber debris and peel fragments from fruit and vegetable raw material cleaning, meat crumbs and seafood shell residues from aquatic and meat product processing, and micro flocs formed in water. The 5μm filtration precision is the optimal choice for canned food processing water: it is precise enough to remove all visible and micro insoluble impurities that cause product quality defects, while avoiding overly fine filtration that leads to excessive flux attenuation, frequent cartridge replacement and increased production costs. At the same time, the 5μm precision balances impurity interception efficiency and dirt-holding capacity, adapting to the high impurity content characteristics of some processing water (e.g., raw material washing water) in canned food production. Under all normal operating conditions (different water temperatures, flow rates and impurity contents), the filtration precision remains stable without attenuation, deformation or filter layer damage, and strictly complies with the national canned food production water quality standards and internal hygiene specifications of the canned food industry, meeting the core impurity-free requirement of processing water for canned food production.
Flux
The flux performance of this 5μm PP winded filter cartridge is fully optimized for the physical properties of canned food processing water (low viscosity, normal temperature), the 5μm fixed precision impurity interception demand, and the large-flow, continuous water supply characteristics of canned food production lines (e.g., large-scale raw material washing, continuous blanching and cooling). Under the standard operating conditions of 20-30℃ (mainstream canned food processing water temperature) and 0.2MPa inlet pressure, the initial pure water flux of a single cartridge reaches 15-30 L/min—a high flux level matching its 5μm precision design, which is far higher than that of finer precision filter cartridges and perfectly adapts to the large water consumption demand of canned food plants. For actual canned food processing water with different impurity contents (the main factor affecting flux stability), the stable operating flux maintains a high and practical level: for low-impurity processing water (e.g., formulation water for brine, cooling water for finished cans), the stable flux is 12-28 L/min per cartridge; for high-impurity processing water (e.g., fruit and vegetable raw material washing water, meat product blanching water), the stable flux is 10-20 L/min per cartridge, unaffected by the normal range of pH value and trace mineral content of processing water. The optimized 5μm filter layer pore structure and high-precision spiral winding process effectively delay flux attenuation during continuous impurity interception, and the flux remains stable in the middle and late stages of use. Even with the gradual accumulation of insoluble impurities, there is no sudden drop in flux, avoiding the reduction of production efficiency of canned food production lines caused by insufficient water supply. In addition, the flux design fully considers the parallel use characteristics in large-flow water treatment systems of canned food plants—dozens or even hundreds of cartridges can be used in parallel in modular food-grade filter housing skids without mutual interference, which can flexibly expand the total filtration flow to hundreds of liters per minute, perfectly meeting the massive and continuous water supply demand of large-scale canned food production lines for raw material washing, blanching, cooling and other processes.
Salt Rejection Rate
As a 5μm food-grade physical impurity interception component for canned food processing water based on the precise pore size interception principle, this filter cartridge is designed to remove insoluble solid impurities in processing water, and its core design concept is to retain all soluble components in water that meet food production standards (e.g., trace mineral ions, soluble inorganic salts, and food-grade additives in formulation water). Therefore, its salt rejection rate is 0% under all normal canned food production operating conditions. It only intercepts suspended solids, sediment, rust particles and other insoluble contaminants in processing water during 5μm precision filtration, and will not retain any soluble components in water, including inorganic salt ions (sodium, potassium, calcium, magnesium) in natural water, soluble food-grade additives (e.g., salt, sugar in brine formulation water), and trace soluble nutrients in blanching water that do not affect product quality. This 0% salt rejection rate is a core performance characteristic of the cartridge for canned food processing water: it strictly ensures that the soluble chemical composition, pH value, total dissolved solids (TDS) content and other physical and chemical indicators of processing water remain completely unchanged after filtration, complying with the differentiated water quality requirements of different canned food production processes (e.g., low-mineral water for fruit canning, mineral-containing brine formulation water for meat canning), and avoiding the loss of soluble food-grade additives in formulation water that affect the taste and preservation of canned food. At the same time, the 0% salt rejection rate makes the cartridge not affected by the TDS content and inorganic salt composition of processing water, and can be universally applied to the impurity interception of various processing water in canned food production, including tap water, well water, municipal purified water and formulated brine water.
Pressure Drop
The pressure drop design of this 5μm PP winded filter cartridge is fully optimized for the 5μm filter layer structure, the rated working pressure of food-grade filter housings for canned food processing, the low-energy production requirements of the food industry, and the normal water supply pressure of canned food production lines (0.15-0.35MPa). It is designed to ensure safe, stable, low-consumption and high-efficiency impurity interception operation, without bringing additional pressure load to the water delivery pump, filter housing system, and various processing equipment of canned food production lines (e.g., washing machines, blanching kettles, cooling tanks). Under the standard operating condition of 25℃ (average canned food processing water temperature) and initial operation state (no impurity accumulation), the initial pressure drop of a single cartridge is strictly controlled within 0.008-0.02 MPa—far lower than the rated pressure loss of mainstream food-grade filter housings for food processing water treatment and canned food production systems. This ultra-low initial pressure drop ensures that the water supply system of canned food plants can operate under normal production pressure without an additional high-pressure booster pump, effectively reducing the energy consumption of the water purification link, and avoiding the damage of pipeline components and processing equipment caused by excessive pressure, which is in line with the energy-saving and emission-reduction requirements of modern large-scale canned food production enterprises. With the progress of continuous filtration and the gradual accumulation of insoluble impurities in the 5μm filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop for canned food processing water impurity interception is 0.25 MPa, which is the critical pressure value for the filter housing system to maintain safe and stable water supply, avoid water leakage and ensure the normal water flow of high-water-consumption processes such as raw material washing and continuous blanching. When the pressure drop reaches this value, the cartridge needs to be replaced in a timely manner, which not only ensures the 5μm precision impurity interception effect of processing water, but also prevents the production line from being shut down due to excessive system pressure and insufficient water supply, and avoids the risk of filter layer rupture caused by overpressure.
Molecular Weight Cutoff (MWCO)
Combined with the fixed 5μm absolute filtration precision, food-grade safety design, uniform filter layer structure and actual impurity interception demand of canned food processing water, the molecular weight cutoff (MWCO) of this filter cartridge is precisely set at 100,000 – 500,000 Da. This MWCO range is perfectly matched with the 5μm filtration precision and the molecular weight characteristics of impurities in canned food processing water, realizing targeted interception of macromolecular insoluble impurities while allowing all small and medium molecular weight soluble components (including water molecules, mineral ions and food-grade additives) to pass through the filter layer smoothly. The 100,000-500,000 Da MWCO can effectively intercept macromolecular insoluble impurities in processing water including plant fiber aggregates (molecular weight >300,000 Da), micro flocculent solids (molecular weight >200,000 Da), rust and scale particle clusters (molecular weight >100,000 Da), and raw material debris aggregates—all of which are the main sources of impurity contamination in canned food processing water. At the same time, this MWCO range ensures the unimpeded passage of all soluble components in processing water that meet food production requirements, such as water molecules (18 Da), inorganic salt ions (23-40 Da), soluble food-grade salt (58.5 Da), sugar (180 Da) and other small molecular weight additives, as well as trace medium molecular weight soluble organic substances in natural water. The high-precision spiral winding process and strict quality control ensure that the MWCO parameters remain stable without attenuation during the service cycle, even under long-term immersion in processing water with different pH values, temperatures and impurity contents, and no adsorption of soluble components occurs. This stable MWCO performance guarantees the consistent and reliable impurity interception effect of the cartridge, achieving both thorough removal of insoluble impurities and complete retention of the original soluble characteristics of processing water, which is fully in line with the water quality requirements of canned food production.
Membrane Thickness
Aiming at the fixed 5μm high-precision impurity interception demand of canned food processing water, the food safety requirements of the canned food industry, the large-flow water supply characteristics and the high impurity content of partial processing water, the filter layer (wound dense food-grade PP wire layer) thickness of this 5μm PP winded filter cartridge is specially designed as 6-8 mm (a fixed thickness matching the 5μm filtration precision), and the total wall thickness of the cartridge (including reinforced porous food-grade PP inner core, 5μm uniform filter layer and food-grade smooth anti-scouring outer protective layer) is 11-13 mm. The dimensional design fully complies with the standard filter cartridge specifications of the food processing industry, ensuring perfect installation compatibility with all mainstream 10/20/40-inch food-grade filter housings (304/316L stainless steel) for canned food processing water treatment systems. The 6-8 mm filter layer is manufactured through a precise high-precision winding process with uniform 5μm pore size distribution, which balances three core performance requirements of 5μm impurity interception for canned food processing water: ultra-high filtration precision to remove all insoluble impurities ≥5μm, excellent water permeability to ensure a high and stable flux for large-flow water supply, and superior dirt-holding capacity to adapt to the high impurity content of partial processing water and extend the service cycle. The reinforced porous food-grade PP inner core with an optimized thickness of 3-4 mm is made of high-strength food-grade PP material, with high compressive strength, uniform water permeability and excellent structural stability. It provides a stable and non-deformable supporting structure for the outer 5μm filter layer under the working pressure (even the maximum allowable pressure of 0.25MPa) of the filter housing system, avoiding the deformation or collapse of the inner core caused by the hydraulic impact of large-flow water delivery, and preventing the pore size of the filter layer from changing due to structural deformation (which would lead to filtration precision attenuation). The food-grade smooth anti-scouring outer protective layer with a thickness of 0.6-0.7 mm is made of modified food-grade PP material, with excellent anti-scouring, anti-corrosion and temperature resistance (adapting to 0-90℃, the full temperature range of canned food processing water including blanching water). It effectively prevents the filter layer from being scoured and damaged by the large-flow water flow during continuous production, avoids the shedding of PP wire particles to ensure the safety and purity of processing water, and the smooth surface is easy to clean and sanitize before use without residue, complying with the strict hygiene control norms of the canned food industry for production water treatment.
Replacement Cycle
The replacement cycle of this 5μm PP winded filter cartridge is determined according to the type of canned food processing water (high-impurity/low-impurity), the continuous production load of the canned food production line, and the raw water quality of processing water, with strict compliance with the canned food industry’s food safety and hygiene control norms and strong on-site operability for canned food manufacturing enterprises. Under the conventional working condition (20-30℃, continuous filtration for 12-16 hours a day, processing water turbidity <10 NTU, matching the rated flow of food-grade filter housings), the recommended replacement cycle for a single cartridge is 10-15 days—a scientific cycle balanced between impurity interception efficiency, dirt-holding capacity and production cost for 5μm impurity interception of canned food processing water. If the cartridge is used for high-impurity processing water (e.g., fruit and vegetable raw material washing water, seafood and meat product cleaning water with high solid debris content) or the processing water turbidity exceeds 10 NTU due to raw water source quality fluctuations, the replacement cycle is shortened to 7-10 days, as the high impurity content will accelerate the accumulation of solids in the 5μm filter layer, leading to faster flux attenuation and pressure drop increase. For canned food production lines in 24-hour continuous full-load production (large-scale automated canned food plants with uninterrupted production), the replacement cycle is also uniformly shortened to 7-10 days to ensure the continuous stability of impurity interception effect, avoid the risk of filter layer blockage and secondary pollution caused by long-term uninterrupted use, and meet the high hygiene requirements of continuous production. In addition, the replacement cycle must be adjusted according to the actual operating parameters of the canned food processing water filtration system: if the pressure drop of the filter housing system reaches the recommended maximum value of 0.25 MPa in advance, or the filtered processing water has obvious turbidity, visible impurities or abnormal color, the cartridge should be replaced immediately regardless of the operating time. Timely replacement not only ensures the impurity-free and hygienic quality of processing water, but also prevents microbial breeding caused by long-term immersion of the cartridge in nutrient-rich processing water (e.g., blanching water with food raw material leachate), complying with the strict food safety control requirements of the canned food industry and avoiding the risk of microbial contamination of canned food products.
