Soy Sauce Membrane Filtration and Impurity Removal Equipment

Soy Sauce Production Membrane Filtration Equipment for Impurity and Sediment Removal—Xihe Fluid Technology Safeguards Purity and Freshness on the Tip of the Tongue

In the millennia-old craft of soy sauce brewing, clarity and stability are critical indicators determining product quality. Traditional soy sauce production relies on processes such as plate and frame filtration and diatomaceous earth filtration, which suffer from low filtration precision, residual impurities, high energy consumption, and loss of flavor compounds, leading to issues like turbidity, excessive sediment, and short shelf life. Addressing these pain points in the soy sauce industry, Xihe Fluid Technology has innovatively developed the **Soy Sauce-Specific Membrane Filtration Equipment for Impurity and Sediment Removal**. Centered on membrane technology, it helps enterprises achieve comprehensive upgrades in efficient clarification, flavor retention, and energy savings, ensuring every drop of soy sauce is pure and fragrant!

I. Three Major Pain Points of Traditional Soy Sauce Filtration Processes
1. High residual impurities: Diatomaceous earth filtration may introduce inorganic particles, while plate and frame filter cloths struggle to trap micron-sized colloids and microorganisms, resulting in turbid soy sauce and recurring sediment precipitation;
2. Loss of flavor compounds: High-temperature sterilization and repeated filtration damage flavor components such as amino acids and sugars, compromising the rich taste of soy sauce;
3. High costs: Frequent replacement of filter materials, significant wastewater discharge, and complex manual operations contribute to overall costs accounting for over 15%.

II. Four Core Advantages of Xihe Membrane Filtration Equipment
1. High-precision impurity removal, mirror-clear with zero sediment
Xihe employs a combined process of **ceramic membranes + polymer ultrafiltration membranes**, precisely trapping impurities such as colloidal particles, microbial residues, and large-molecule proteins in soy sauce through 0.1-0.5μm pores. The filtered soy sauce achieves a light transmittance of >95%, with no sediment precipitation during long-term storage, completely resolving consumer complaints about "residual bottom sludge."

2. Low-temperature operation throughout, locking in fresh aroma and original flavor
The membrane filtration process requires no high-temperature heating, removing microorganisms (bacteria removal rate >99.9%) at room temperature while fully preserving over 300 flavor compounds, including amino acids, reducing sugars, and esters. The loss rate of umami indicators (amino acid nitrogen) is <3%, resulting in a richer taste and quality comparable to high-end brewed soy sauce.

3. Energy savings and reduced consumption, cutting overall costs by 40%
- Water savings: Membrane filtration reduces water consumption by 60% compared to traditional processes, with cleaning wastewater recyclable;
- Time efficiency: Fully automated process increases filtration efficiency by 2 times, with daily processing capacity reaching 100 tons;
- Material reduction: No need for consumables like diatomaceous earth or filter cloths, saving over ¥500,000 annually (based on a 10,000-ton annual production soy sauce factory).

4. Intelligent cleaning, long-term stable operation
The equipment is equipped with a **pulse backwash + online CIP cleaning system**, monitoring membrane flux changes in real time and automatically triggering cleaning procedures. Membrane lifespan extends to over 3 years, eliminating downtime losses caused by frequent filter material replacements in traditional processes.

III. Three Application Scenarios of Xihe’s Solutions
1. Rough filtration of raw soy sauce: Replaces plate and frame filtration, efficiently removing large particles like bran and bean residue, increasing pretreatment efficiency by 80%;
2. Fine filtration before sterilization: Ultrafiltration membranes remove colloids and microorganisms, reducing subsequent high-temperature sterilization requirements (from 120°C to 85°C) and minimizing burnt flavors from excessive Maillard reactions;
3. Polishing of finished soy sauce: Nanoscale precision filtration ensures clarity and absence of suspended particles before bottling, enhancing premium product value.
