Pharmaceutical Vacuum Loader Technical Principle

The pharmaceutical vacuum loader uses a vacuum pump to create a negative pressure environment. It utilizes the pressure differential between the inside and outside of the pipeline to draw materials from a storage silo or container into a sealed pipeline and transport them to the target location. Its core process can be divided into three steps.

Starting the vacuum pump: After the vacuum pump is started, the internal pressure of the system rapidly decreases, creating a vacuum environment.

Material Adsorption: Under the action of negative pressure, the material is drawn into the pipeline through the suction nozzle, where it mixes with the airflow to form a gas-solid two-phase flow.

Gas-Solid Separation: After reaching the destination, the material passes through a filter or cyclone separator to separate the gas and solids. The material falls into a storage tank, and the gas is discharged after dust removal.

Pharmaceutical Vacuum Loader Components

The Pharmaceutical Vacuum Loader uses negative pressure pneumatic conveying technology to automatically convey powders and granular materials. Its core structure consists of a vacuum pump, filtration system, control system, conveying pipeline, and auxiliary components. These components work together to ensure efficient, clean, and safe material transportation.

The vacuum pump:It is the power source of the pharmaceutical vacuum loader. It extracts air from the system to create a stable negative pressure of 0.4-0.6 bar, providing critical energy for material suction and conveying.

The filtration system:It is critical for ensuring material purity and equipment life. It uses various filter types to achieve precise air-material separation.

The control system:Based on a PLC, it allows preset parameters such as conveying time and backflush frequency, enabling automated equipment operation and significantly reducing manual intervention. Combined with an automatic material level control device, a sensor monitors the material level in the hopper and automatically starts and stops the vacuum pump, enabling unmanned operation.

Conveying Pipes and Auxiliary Components:The conveying pipe is made of wear- and corrosion-resistant stainless steel, connecting the suction nozzle to the target equipment. The suction nozzle can be designed to suit the characteristics of different materials, such as powders and granules. The vacuum hopper can store materials in a sealed manner to prevent contamination. The pneumatic discharge gate device allows precise discharge of materials through pneumatic control once the materials reach the target location.

What types of filters are available for pharmaceutical vacuum loaders?

The filter is a core component in a pharmaceutical vacuum loader, and its choice of filter type directly impacts conveying efficiency, material purity, and equipment life. The pharmaceutical industry's stringent requirements for cleanliness, corrosion resistance, and explosion resistance are crucial.

Membrane-coated bag filters: Utilizing PTFE membrane technology, they intercept fine dust and microorganisms from pharmaceutical raw materials. Their smooth surface resists dust adhesion, supports backflushing or pulse cleaning, and features an anti-static design to eliminate static electricity risks. They are suitable for conveying flammable and explosive materials.

Stainless steel membrane filters: Made of stainless steel, they offer strong acid and alkali corrosion resistance and high temperature tolerance, and can withstand sterilization. They are suitable for conveying chemical-containing materials such as traditional Chinese medicine extracts and biopharmaceutical fermentation broths.

PE-coated bag filters: Made of polyester fiber, they are coated with a high-precision polytetrafluoroethylene microporous membrane, creating a "surface filtration" structure. Their filtration accuracy meets the requirements for intercepting ultrafine dust and microorganisms found in the pharmaceutical and food industries. The smooth surface of the PTFE membrane resists dust adhesion, and combined with pulse backflushing or pneumatic cleaning systems, particles can be quickly removed from the filter surface.

Titanium filters: They offer exceptional corrosion resistance, making them resistant to highly corrosive media such as concentrated hydrochloric acid and aqua regia. They also offer the advantages of being lightweight and biocompatible. These filters are designed for extreme applications, such as preventing radiation degradation in radiopharmaceutical production and combating chemotherapy drug corrosion during the transportation of anticancer drug raw materials, ensuring stable equipment operation and operator safety.

Which filter type is best suited for pharmaceutical vacuum loaders?

Pharmaceutical companies must comprehensively select a filter based on material characteristics, process requirements, and budget. Economical membrane filter bags are preferred for conveying general pharmaceutical powders; stainless steel filters are recommended for chemical raw materials or high-temperature sterilization; membrane filters are suitable for high-precision applications such as sterile preparations and inhalation preparations. Titanium filters are essential for extreme conditions such as those involving strong corrosion and radiation. By precisely matching filter types, companies can optimize production efficiency, product quality, and cost control.

The Pharmaceutical Vacuum Loader can be used in tandem with multiple devices.

In pharmaceutical production, combining a screening machine, mixer, Pharmaceutical Vacuum Loader, and packaging machine in tandem creates an efficient, closed, automated production line, seamlessly integrating the entire process from raw material pretreatment to finished product packaging.

As raw material pretreatment equipment, the screening machine, equipped with a vibrating or rotary screen, removes lumps, impurities, and oversized particles, ensuring uniform particle size for improved subsequent mixing. A sealed hood is also installed to prevent dust leakage. Subsequently, a pharmaceutical vacuum loader provides closed-loop conveying. Made of stainless steel, it automatically starts and stops according to the material level in the mixer, allowing unmanned operation. It transfers the screened material from the screening hopper to the mixer. The mixer is responsible for mixing various raw materials in proportion to ensure uniformity. Depending on the material characteristics, a V-shaped, three-dimensional motion, or double-cone mixer can be selected, equipped with a sealed feed port to connect to the vacuum loader. Another pharmaceutical vacuum loader performs secondary conveying, equipped with a pressure-resistant vacuum pump for long-distance transport, transferring the mixed material from the mixer to the packaging machine hopper. Finally, the packaging machine, which can be an automatic bottling line, bag filling machine, or blister packaging machine, completes the quantitative packaging of the materials and the packaging of the finished products.
