Product Introduction
Traditional cake filtration and diatomaceous earth filtration—commonly referred to as direct-flow filtration—involve the slurry flowing perpendicular to the surface of the filter medium, with solids being retained by the medium and gradually forming a filter cake. As filtration continues and the cake thickens, the filtration rate declines markedly until the filtrate ceases to flow. By contrast, rice vinegar filters employ cross‑flow filtration, which operates on the principle of using a circulation pump to drive the feed material through the pores of a membrane with varying pore sizes at high velocity. Under pressure, the filtrate is forced tangentially across the membrane, while the retentate, driven by its high velocity, generates turbulence that continuously rinses the membrane surface, carrying away any solid particles adhering to it. This prevents membrane fouling and ensures sustained, stable filtration. Compared with conventional dead‑end filtration, cross‑flow filtration offers significant advantages. For instance, under identical conditions, the filtrate flow rate in dead‑end filtration can drop to zero within minutes, whereas cross‑flow filtration maintains a nearly constant flow. Moreover, cross‑flow filtration is insensitive to variations in feed concentration, enabling effective filtration of highly contaminated liquids without prior pretreatment.
Working principle
1. The membrane material, which is high-strength, acid- and alkali-resistant, and oxidation‑resistant, can withstand intensive, frequent backflushing as well as prolonged, high‑concentration chemical cleaning, thereby ensuring long service life and low operating costs.
2. With a fixed pore size and no filter aid added, the filtration performance is stable and reliable, completely eliminating the various sources of instability inherent in diatomaceous earth filtration as well as the environmental burdens associated with spent filter cake disposal.
3. High-precision, sterilizing-grade filtration delivers exceptionally clear effluent, achieving a sterilization efficiency of over 99%, while having no adverse impact on valuable bioactive compounds in food, such as sugars, amino acids, alcohols, and lipids.
4. It can handle filtration of highly turbid and highly viscous liquids, completing both coarse and fine filtration in a single step, eliminating the need for conventional cotton‑cake or diatomaceous earth filters as pre‑filters.
5. The unique cross-flow process design and automated self‑cleaning during operation ensure continuous, large‑scale separation; compared with conventional membrane separation equipment, it improves separation efficiency by more than 40% and delivers outstanding anti‑fouling performance.
6. The filter membrane assembly features a quick‑release, detachable design; when necessary, the membrane module can be removed for thorough offline cleaning, ensuring superior cleaning performance. Additionally, the reusable housing significantly reduces the cost of membrane replacement.
7. The most practical modular separation unit design allows for operation using all or only selected separation modules, depending on the total separation volume, offering advantages such as a small footprint, low energy consumption, minimal liquid holdup, and reduced waste.
8. The system employs a PLC‑based automated control system, offering exceptionally simple operation. Optional online monitoring and protection of key separation parameters—such as temperature, pressure, and turbidity—ensure that improper operation does not compromise equipment performance or separation efficiency.
9. CIP‑type automatic cleaning and disinfection, convenient and thorough, ensures ideal restoration of the membrane’s separation performance.
10. The entire machine is manufactured from food-grade stainless steel 304 or 316L, complying with national food and pharmaceutical hygiene standards as well as QS/GMP certification requirements.
Product Applications
The rice vinegar filter, also known as a liquid cross-flow membrane filtration unit, is suitable for processing liquids such as yellow wine, rice wine, baijiu, fruit wine, grape wine, cooking wine, edible vinegar, soy sauce, and tea beverages.
