Application of industrial filter cloth in glutamic acid production in the biotechnology industry
—— A highly efficient filtration solution adapted to horizontal vacuum belt filters
I. Background: Challenges of solid-liquid separation in glutamic acid production
Glutamic acid is an important amino acid widely used in food, medicine, chemicals, and feed additives. The current mainstream production process is microbial fermentation, which includes multiple stages such as fermentation, centrifugation, filtration, concentration, and crystallization.
Among them, Solid-liquid separation of fermentation broth is one of the key steps. If a large amount of fermentation residue (bacteria) is not removed promptly and efficiently, it will seriously affect the efficiency and product quality of the downstream concentration and purification processes. Although traditional centrifugal equipment can achieve a certain separation effect, it has problems such as high energy consumption, intermittent operation, and frequent maintenance.
Driven by the demand for continuous, high-efficiency, and low-cost production, ** Horizontal vacuum belt filter ( Horizontal Vacuum Belt Filter, HVBF ) ** has been adopted by more and more glutamic acid production companies due to its continuous operation, high processing capacity, and low filter cake moisture content. The core component of this equipment, —— industrial filter cloth directly determines its operating performance and economy.
II. Equipment matching: Introduction to horizontal vacuum belt filter
A horizontal vacuum belt filter is a continuous vacuum filtration equipment that achieves continuous solid-liquid separation through the movement of the filter cloth and vacuum.
- Filter cloth (continuous operation)
- Vacuum chamber
- Filtrate collection system
- Automatic cloth washing device
- Filter cake scraping system
Its operation process is as follows: The glutamic acid fermentation broth to be treated is evenly distributed on the filter cloth by the feeding device, and the liquid is extracted under negative pressure to form a filter cake. After washing and drying, the filter cake is scraped off by a scraper, and the filter cloth is cleaned and recycled.
Therefore, the permeability, filtration accuracy, mechanical strength, and filter cake release performance of the filter cloth are directly related to the efficiency and stability of the equipment.
III. Application characteristics: Special requirements for filter cloth in glutamic acid filtration
The filtration conditions of glutamic acid fermentation broth are complex and contain high-viscosity organic matter, microbial cells, and residual nutrients. This puts the following requirements on the filter cloth:
- Good air and liquid permeability : Ensure that the liquid can quickly pass through the filter cloth to improve the filtration rate and avoid " Clogging ” phenomenon;
- Appropriate filtration accuracy : It can effectively intercept microbial cells without causing rapid blockage, maintaining stable operation of the filter cloth;
- Excellent filter cake release performance : Strong filter cake adhesion is a common problem in glutamic acid filtration, and easy-to-release filter cloth helps improve automation efficiency;
- Resistance to biological load and acidic environment : The fermentation broth often contains organic acids and active bacteria, and the filter cloth must have strong chemical stability;
- Mechanical strength and cleaning ability : The filter cloth needs to withstand repeated tension and vacuum negative pressure, and adapt to high-frequency CIP cleaning process;
- Stable size and processing accuracy : Ensure that the filter cloth does not deviate or curl during long-term operation.
