Product Description

The Medical vacuum filter is a solid-liquid separation device operating continuously under vacuum conditions. Specifically designed for the pharmaceutical industry, it features high-precision filtration, continuous production capability, and a high level of automation.

Working Principle

The drum is partially immersed in the slurry tank. A vacuum is created inside the drum by a vacuum pump, drawing the liquid from the slurry into the drum’s inner cavity for discharge, while solid particles are trapped on the drum surface to form a filter cake. As the drum rotates one full cycle, it sequentially completes the entire process of filtration, washing, drying, discharging and filter cloth regeneration.

Core Structure of the Medical vacuum filter

Drum: Horizontally mounted, with perforations on the surface and covered with filter cloth and support plates.

Distributor Valve: Controls the connection of each filter chamber to vacuum and compressed air.

Slurry Tank: Holds the slurry to be filtered, with the lower part of the drum submerged in it.

Scraper/Belt Turning Device: Used for filter cake discharge.

Control System: PLC automatic control enables parameter monitoring and adjustment.

· Uniform Filter Cake Forming Technology: Controllable filter cake thickness ensures consistent washing results, helping to enhance product purity and quality stability.

Customized Design for the Pharmaceutical Industry

· Material Selection: All material-contacting components are made of 316L/904L stainless steel or C276 alloy, complying with GMP requirements for material inertness. These materials do not release particles or adsorb pharmaceuticals.

· Surface Treatment: The inner surface features mirror polishing, with no dead corners or blowholes. It is easy to clean and disinfect, preventing cross-contamination.

· Hermetic Design: Equipped with sanitary-grade seals to minimize the leakage of pharmaceutical dust, which not only protects the occupational health of operators but also maintains the cleanliness of the production environment.

· Cleaning System: Supports automated cleaning processes without equipment disassembly, fully aligning with Good Manufacturing Practices (GMP) and enhancing cleaning efficiency and compliance.

Technical Specifications

Application Fields

The Medical vacuum filter is a widely used solid-liquid separation device in the pharmaceutical industry. Its core working principle relies on vacuum suction to form a filter cake on the drum surface, achieving efficient separation of solid particles from liquids in the suspension. Boasting advantages such as continuous operation, high automation, large processing capacity, and low filter cake moisture content, this equipment is particularly suited for pharmaceutical production processes with stringent requirements for hygiene conditions and product purity.

· Antibiotic Production

Used for solid-liquid separation of fermentation broths of penicillins, erythromycins, cephalosporins and other antibiotics, separating mycelia from mother liquors.It can effectively recover valuable metabolites and reduce the load of subsequent extraction processes.

· Traditional Chinese Medicine (TCM) Extraction and Refinement

Liquids obtained through water or ethanol extraction of TCM raw materials contain active ingredients, but also carry medicinal residues, insoluble impurities and other unwanted substances.Suitable for clarifying and filtering extracts of TCM materials such as ginseng, astragalus membranaceus, and honeysuckle.

· Vitamin and Amino Acid Manufacturing

Separates cells or crystals from fermentation broths of vitamin C, B-group vitamins, lysine, glutamic acid and other products.

· Biopharmaceutical Production

Applied in cell harvesting or culture broth clarification during the production of biological products including vaccines, enzyme preparations, and protein-based drugs.

· Active Pharmaceutical Ingredient (API) Refinement

Performs solid-liquid separation of APIs after recrystallization, yielding crystalline products with high purity and low moisture content.

· Pharmaceutical Intermediate Production

Conducts filtration and washing of reaction mixtures during the synthesis process, improving product yield and purity.

FAQ

Q: What is the replacement cycle for the equipment's wearing parts (e.g., filter cloth, seals)?

A: Under normal operating conditions, the filter cloth should be replaced every 3–6 months and the seals every 6–12 months. Featuring a snap-fit and modular design, replacement can be independently completed by regular operators without special tools, ensuring convenient and hassle-free maintenance.

Q: Does the equipment comply with pharmaceutical industry standards? What hygiene and safety guarantees are provided?

A: The equipment is fully compliant with pharmaceutical industry certification standards. All material-contacting components are made of 316L stainless steel with a polished surface that eliminates hygiene dead corners. The sealing system adopts food-grade sterile seals to prevent leakage and cross-contamination.

Q: Can the filtration accuracy meet pharmaceutical requirements? Is parameter adjustment supported?

A: The filtration accuracy ranges from 0.1 to 50 μm, capable of retaining fine impurities and microorganisms. The drum speed and vacuum level can be adjusted via frequency conversion to adapt to pharmaceutical materials with different viscosities and solid contents, eliminating the need to replace core components.

Q: What are the components of daily maintenance costs?

A: Maintenance costs are transparent, mainly covering wearing parts, a small amount of cleaning fluid consumables and energy consumption. Equipped with a high-efficiency and energy-saving vacuum pump, the equipment reduces energy consumption by over 30% compared to traditional models, with no hidden costs. Core components come with a 2-year warranty, and the designed service life exceeds 10 years.

Q: What is the after-sales service response and support in case of equipment failure?

A: 24/7 online technical support is available. Core components are replaced free of charge during the warranty period. Installation training and lifetime technical support are also provided.
