Application of industrial filter cloth in horizontal vacuum belt filter for corn lactic acid liquid filtration
With the development of green biomanufacturing and clean fermentation processes, corn, as an important renewable raw material, is widely used in the production of lactic acid and its derivatives. In the extraction and purification of corn lactic acid liquid, solid-liquid separation is a crucial step. And horizontal vacuum belt filter ( Horizontal Vacuum Belt Filter, HVBF ) with dedicated industrial filter cloth has become the core equipment and material configuration for achieving continuous and efficient filtration.
Process background: Filtration needs of corn lactic acid liquid
Lactic acid production usually uses starch saccharification fermentation technology. The fermentation broth contains a large amount of solid residue, microbial cells, and unconverted raw materials. To ensure product purity and improve the efficiency of subsequent concentration and refining, lactic acid liquid must undergo pre-treatment filtration to remove suspended solids and impurities.
Traditional gravity sedimentation or plate and frame filter press has low filtration efficiency and poor automation, while horizontal vacuum belt filter with customized filter cloth can provide stable continuous operation capability, especially suitable for liquids such as fermentation broth with moderate viscosity and suspended solids load.
Technical advantages of horizontal vacuum belt filter
- Continuous operation, high efficiency Suitable for 24 24/7 uninterrupted production;
- Vacuum-assisted dehydration, thorough solid-liquid separation ；
- Stable filter cloth running trajectory, automatic tensioning and deviation correction ；
- Suitable for bio-fermentation materials with different particle sizes and viscosities 。
Key performance requirements of industrial filter cloth
For fine particles, colloidal impurities, and microbial residues in corn lactic acid liquid, the filter cloth needs to have the following properties:
1. Precise filtration accuracy
Using fine weaving or multi-layer structure can effectively intercept micron-level suspended solids, while maintaining an appropriate air and liquid permeability rate to avoid blockage and excessive pressure drop.
2. Excellent chemical resistance
Lactic acid liquid has a certain acidity, and the filter cloth must have good acid and fermentation liquid corrosion resistance Commonly used polyester ( PET ), polypropylene ( PP ) monofilament / multifilament materials are all available.
3. High mechanical stability
During the operation of the filter, the filter cloth needs to withstand vacuum suction, tension, and material friction, so it needs to have high tensile strength and wear resistance.
4. Easy to clean, strong regenerability
The filter cloth should have good smoothness and soil resistance for easy and quick cleaning by the online washing system, reducing downtime and extending service life.
Filter cloth structure and application effect
Common structures include:
- Single-layer or double-layer high-permeability filter cloth
- Medium pore size composite fabric (supports pre-coating operation)
- Continuous running filter belt with reinforced border and loop connector
The use effect can achieve:
- Removal rate of 95% or more solid impurities;
- High filtrate transparency, reduced subsequent evaporation load;
- Long filter cloth service life, low maintenance cost.
Industry application value
This solution has been widely used in lactic acid, citric acid, tartaric acid and other organic acid fermentation industries playing an irreplaceable role in the pretreatment and purification of bio-fermentation broth. It not only improves filtration efficiency but also promotes the efficient use of corn resources and the upgrading of green lactic acid manufacturing processes.
