Product Introduction
This 40-inch PP wire-wound filter cartridge is a high-performance industrial food-grade filtration component specially engineered for the impurity removal process of vinegar, soy sauce and plant extracts, tailored to the large-flow production demand of condiment and plant extract processing industries. Crafted from high-purity food-grade polypropylene (PP) raw materials complying with FDA, EU 10/2011 and national food safety standards for condiments, the cartridge adopts advanced precision spiral winding technology and is exclusively designed in the industry-standard 40-inch specification, equipped with a reinforced food-grade porous PP inner core and a uniformly structured PP wire filter layer. It is dedicated to the efficient interception of insoluble impurities in vinegar (brewed vinegar, fruit vinegar), soy sauce (light soy sauce, dark soy sauce, brewed soy sauce) and plant extracts (herbal extracts, fruit and vegetable extracts, botanical active ingredient extracts), including raw material residue, fiber debris, suspended solids, colloidal substances, sediment and fine particulate matter generated during fermentation and extraction. The filtration process achieves physical impurity removal without chemical reactions, no dissolution of harmful substances, no secondary pollution, and no damage to the original flavor, nutritional active ingredients, acidity and flavor substances of the processed liquids. With large-flow filtration performance, stable impurity removal efficiency, perfect compatibility with 40-inch standard food-grade filter housings, and excellent adaptability to the acidic and high-salt characteristics of vinegar and soy sauce, this 40-inch cartridge is a core cost-effective filtration component for condiment factories, plant extract processing enterprises and food raw material manufacturers, complying with the strict food safety and large-scale industrial production requirements of the food processing industry, and laying a solid foundation for the subsequent refining, filling and storage of vinegar, soy sauce and plant extracts.
Filtration Precision
Calibrated specifically for the impurity characteristics of vinegar, soy sauce and plant extracts, and the differentiated filtration needs of different production processes (rough filtration, fine filtration), the filtration precision of this 40-inch PP wire-wound filter cartridge covers a customizable food industry standard range of 5 μm to 50 μm, with the most practical and commonly used specifications for actual production being 10 μm, 20 μm, 30 μm and 40 μm. The 10 μm high-precision specification is suitable for the fine impurity removal of high-grade brewed vinegar, premium soy sauce and high-purity plant extracts (botanical active ingredients), effectively intercepting micro colloidal impurities, fine raw material residue and tiny suspended solids that affect the transparency, clarity and product grade of the finished product; the 20 μm medium-precision specification is the universal choice for the conventional filtration of mainstream vinegar and soy sauce products, removing fiber debris, fermentation residue and large colloidal substances to ensure the basic clarity of condiments and prevent clogging of subsequent filling equipment; the 30 μm and 40 μm specifications are applicable to the rough impurity removal of primary vinegar, raw soy sauce and crude plant extracts with high solid content, intercepting large granular raw material residue, sediment and bulk fiber debris to reduce the impurity load of subsequent fine filtration links. All precision grades adopt food-grade gap-calibrated winding technology, with uniform filtration gaps, stable interception efficiency and no precision attenuation or channeling during continuous large-flow industrial production, fully meeting the differentiated impurity removal requirements of vinegar, soy sauce and plant extracts in different production stages, as well as the quality standards of different grades of finished products.
Flux
The flux performance of this 40-inch PP wire-wound filter cartridge is fully optimized for the 40-inch extended standard specification, the physical and chemical properties of vinegar, soy sauce and plant extracts (acidic, high-salt, medium viscosity) and the large-flow industrial production demand of the condiment and plant extract processing industries. Under the standard operating conditions of 25℃ (the mainstream processing temperature of condiments and extracts) and 0.2MPa inlet pressure, the initial pure water flux of the 40-inch single cartridge reaches 40-100 L/min—far higher than that of conventional short-specification cartridges, perfectly matching the large-flow production line demand. For actual processed liquids with different characteristics, the stable operating flux maintains a high and adaptive level: for low-viscosity vinegar (acetic acid content 3-8%) and soy sauce (salt content 15-20%), the stable flux is 35-90 L/min per 40-inch cartridge; for medium-viscosity plant extracts (including herbal extract paste and fruit and vegetable concentrate), the stable flux is 30-70 L/min per 40-inch cartridge, unaffected by the acidity, salt content and moderate viscosity of the liquid. The flux attenuation rate of the cartridge is strictly controlled during continuous large-flow filtration, and the flux remains stable in the middle and early stages of use. Even with the gradual accumulation of insoluble impurities, there is no sudden drop in flux, avoiding the reduction of the overall production efficiency of the vinegar, soy sauce and plant extract processing lines caused by excessive flux attenuation. In addition, the flux design fully considers the parallel use characteristics in ultra-large-flow filtration systems, and multiple 40-inch cartridges can be used in parallel without mutual interference, which can flexibly expand the total filtration flow to meet the mass production needs of large-scale condiment factories and plant extract processing enterprises.
Salt Rejection Rate
As a food-grade physical impurity removal component based on the pore size interception principle, this 40-inch PP wire-wound filter cartridge is designed to remove insoluble solid impurities in vinegar, soy sauce and plant extracts, and does not have the functional design of desalination, ion removal, acid separation or separation of dissolved substances (such as soluble amino acids, organic acids, mineral ions, plant active ingredients). Therefore, its salt rejection rate is 0% under all normal food processing operating conditions. It only intercepts raw material residue, fiber debris, suspended solids and other insoluble contaminants in the liquid during filtration, and will not retain any soluble components in vinegar, soy sauce and plant extracts, including salt ions, acetic acid, amino acids, soy sauce peptides, plant polyphenols, flavonoids and other nutritional and functional active ingredients. This characteristic is crucial for the processing of vinegar, soy sauce and plant extracts: it ensures that the acidity, salt content, soluble nutrient ratio, original flavor and active ingredient content of the processed liquids remain completely unchanged after impurity removal, avoiding the loss of key soluble components that affect the taste, quality and efficacy of the finished product, and complying with the strict process parameter requirements of condiment and plant extract production. At the same time, the 0% salt rejection rate makes the cartridge not affected by the salt content, acidity and soluble solid content of the liquid, and can be universally applied to the impurity removal of all types of vinegar, soy sauce and plant extracts with different components and concentrations.
Pressure Drop
The pressure drop design of this 40-inch PP wire-wound filter cartridge is fully optimized for the 40-inch standard specification, the rated working pressure of 40-inch large-flow food-grade filter housings, the low-energy production requirements of the food processing industry, and the physical characteristics of vinegar, soy sauce and plant extracts (acidic, high-salt). It is designed to ensure safe, stable and low-consumption large-flow filtration operation without bringing additional pressure load to the liquid delivery pump and pipeline equipment of the vinegar, soy sauce and plant extract processing lines. Under the standard operating condition of 25℃ and initial operation state (no impurity accumulation), the initial pressure drop of the 40-inch single cartridge is strictly controlled within 0.02-0.05 MPa, which is far lower than the rated pressure loss of mainstream 40-inch large-flow food-grade filter housings and food processing systems. This low initial pressure drop ensures that the sanitary delivery pump of the food production line can operate at the rated pressure without increasing the working load, effectively reducing the energy consumption of the impurity removal link, and avoiding the corrosion and damage of pump impellers and pipeline components caused by excessive pressure under acidic and high-salt conditions, which is in line with the energy-saving and emission-reduction requirements of modern food processing enterprises. With the progress of continuous large-flow filtration and the gradual accumulation of intercepted insoluble impurities in the filter layer, the pressure drop of the cartridge will increase steadily. The recommended maximum allowable pressure drop for food liquid impurity removal is 0.25 MPa, which is the critical pressure value for the 40-inch filter housing system to maintain safe and stable operation, avoid liquid leakage and ensure the normal progress of subsequent processing links (refining, filling). When the pressure drop reaches this value, the cartridge needs to be replaced in a timely manner, which not only ensures the impurity removal effect of vinegar, soy sauce and plant extracts, but also prevents the production line from being shut down due to excessive system pressure and affecting the continuous mass production of food raw materials and condiments.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision range, 40-inch large-flow specification, food-grade safety design and actual impurity removal demand of vinegar, soy sauce and plant extracts, the molecular weight cutoff (MWCO) of this filter cartridge is set at 150,000 – 700,000 Da, and the MWCO grade is precisely matched with the filtration precision one by one to realize targeted interception of macromolecular insoluble impurities without intercepting small molecular weight soluble flavor substances, nutritional components and plant active ingredients. The 10 μm high-precision cartridge with MWCO of 150,000 – 300,000 Da can effectively intercept small molecular weight colloidal impurities, fine macromolecular raw material residue and protein aggregates in high-grade vinegar, premium soy sauce and high-purity plant extracts, ensuring the high transparency and clarity of the finished product and avoiding sedimentation during storage; the 20 μm medium-precision cartridge with MWCO of 300,000 – 450,000 Da is suitable for intercepting macromolecular insoluble impurities such as fiber debris, fermentation residue and colloidal starch aggregates in mainstream vinegar and soy sauce products; the 30 μm and 40 μm rough filtration cartridges with MWCO of 450,000 – 700,000 Da can efficiently remove large molecular weight insoluble contaminants such as bulk raw material residue, sediment and plant fiber bundles in primary vinegar, raw soy sauce and crude plant extracts. This graded MWCO design not only ensures the efficient removal of harmful insoluble impurities in vinegar, soy sauce and plant extracts during large-flow filtration, but also allows all small molecular weight soluble components (acetic acid, salt ions, amino acids, plant polyphenols, flavonoids, vitamins) to pass through the filter layer smoothly, maximizing the retention of the original flavor, nutritional value and functional efficacy of the processed liquids. At the same time, the high-purity food-grade PP raw material and precision spiral winding process ensure that the MWCO parameters remain stable without attenuation during the service cycle, even under the long-term erosion of acidic and high-salt liquids, ensuring the consistent and stable impurity removal effect of the large-flow processing line.
Membrane Thickness
Aiming at the 40-inch extended standard specification, food safety requirements of the food processing industry, the acidic and high-salt characteristics of vinegar and soy sauce, and the continuous large-flow impurity removal characteristics of vinegar, soy sauce and plant extracts, the filter layer (wound food-grade PP wire layer) thickness of this 40-inch PP wire-wound filter cartridge is specially designed as 6-14 mm with graded specifications, and the total wall thickness of the cartridge (including reinforced food-grade porous PP inner core, filter layer and food-grade smooth anti-corrosion outer protective layer) is 14-22 mm, fully complying with the dimensional standard of 40-inch food-grade filter cartridges to ensure perfect installation compatibility with all mainstream 40-inch large-flow food-grade filter housings (304/316L stainless steel, anti-corrosion PP). The thin filter layer (6-8 mm) is matched with the 10 μm high-precision cartridge for the fine impurity removal of high-grade vinegar, premium soy sauce and high-purity plant extracts, which ensures high filtration precision and excellent liquid permeability under normal operating conditions, avoiding excessive flow resistance caused by overly thick filter layer and affecting the production efficiency of the high-grade product processing line; the medium filter layer (9-11 mm) is applied to the 20 μm universal cartridge for the conventional filtration of mainstream vinegar and soy sauce, balancing filtration precision and dirt-holding capacity to adapt to the continuous large-flow production demand of condiment factories; the thickened filter layer (12-14 mm) is matched with the 30 μm and 40 μm rough filtration cartridges for primary vinegar, raw soy sauce and crude plant extracts with high solid content, providing a larger three-dimensional dirt-holding space to intercept more insoluble impurities, extend the service cycle of the cartridge and reduce the replacement frequency under large-flow working conditions. The reinforced food-grade porous PP inner core with optimized thickness (5-7 mm) has high compressive strength and uniform water permeability, and excellent anti-corrosion performance under acidic and high-salt conditions, which provides a stable and non-deformable supporting structure for the outer filter layer under the working pressure of the 40-inch large-flow filter housing system, avoiding the deformation or collapse of the inner core and ensuring the overall structural stability of the 40-inch cartridge. The food-grade smooth anti-corrosion outer protective layer (0.8-1.2 mm) is made of modified high-purity food-grade PP material, with acid and salt resistance, effectively preventing the filter layer from being eroded and damaged by acidic and high-salt liquids during continuous filtration, avoiding the shedding of PP wire particles to ensure food safety, and is easy to clean and sanitize before use, complying with the hygiene control norms of the food processing industry.
Replacement Cycle
The replacement cycle of this 40-inch PP wire-wound filter cartridge is determined according to the type of processed liquid (vinegar, soy sauce, plant extract), filtration precision specification, solid content of the liquid and the continuous large-flow production load of the processing line, with strict compliance with food safety and hygiene norms and strong on-site operability for industrial production. Under the conventional working condition (25℃, continuous industrial production for 8-16 hours a day, matching the rated flow of 40-inch large-flow filter housings, liquid solid content <8%), the recommended replacement cycle for the 40-inch single cartridge is 3-6 weeks for different specifications: the 10 μm high-precision cartridge for high-grade products has a replacement cycle of 3-4 weeks due to high filtration precision and relatively fast impurity accumulation; the 20 μm universal cartridge for mainstream condiments has a replacement cycle of 4-5 weeks, balancing production efficiency and filtration effect; the 30 μm and 40 μm rough filtration cartridges for high-solid-content liquids have the longest replacement cycle of 5-6 weeks with the largest dirt-holding capacity. If the food production line is in 24-hour continuous ultra-high load operation (the mainstream production mode of large-scale condiment factories and plant extract processing enterprises), or the liquid solid content is higher than 8%, the replacement cycle of all specifications of 40-inch cartridges will be uniformly shortened to 2-4 weeks—continuous high-flow operation and high solid content will accelerate the accumulation of impurities on the filter layer, and timely replacement can avoid the reduction of impurity removal effect, the clogging of subsequent processing equipment, and the risk of microbial breeding caused by long-term use of the cartridge under acidic conditions, which is in strict compliance with the food safety and hygiene control requirements of the food processing industry. In addition, the replacement cycle needs to be adjusted according to the actual operating parameters of the large-flow filtration system: if the pressure drop of the 40-inch filter housing system reaches the recommended maximum value of 0.25 MPa in advance, or the impurity removal effect is significantly reduced (the liquid has obvious turbidity, visible impurities or causes slight clogging of the subsequent filling pipeline), the cartridge should be replaced immediately regardless of the operating time, to ensure the consistent impurity removal quality of vinegar, soy sauce and plant extracts, and the smooth progress of the subsequent refining, filling and storage processes.
