Fully automatic models are designed for high-speed, large-scale production and are suitable for industries with continuous production needs.

Inline Auger Filler

Inline auger fillers feature a horizontal setup where the containers move along a conveyor belt, and the auger fills each container as it passes. These systems are ideal for industries that need to fill large quantities of containers quickly and accurately in a streamlined, efficient manner.

Rotary Auger Filler

Rotary auger fillers are designed for filling large quantities of powder or granular products into multiple containers in a rotating motion. These machines are often used in applications that require high speed and precision, such as in the food and pharmaceutical industries.

Auger Filler with Vacuum Systems

Auger fillers equipped with vacuum systems are designed to handle powders that are prone to dusting, like powdered milk or flour. The vacuum system helps to control the dust and prevents spillage during the filling process. These machines are highly beneficial in maintaining a clean and dust-free production environment.

Auger Filler with Check Weigher

This type of auger filler is integrated with a checkweigher, which ensures that each container is filled with the correct amount of product. If a container deviates from the preset weight, it is rejected, ensuring quality control in the filling process. This setup is typically used in industries where regulatory compliance and accuracy are vital, such as in pharmaceuticals and food processing.

Auger Filler for Viscous Liquids

Some auger fillers are designed specifically to handle viscous or thick products, such as creams, gels, and pastes. These fillers use a modified auger system and additional mechanisms to ensure that thicker substances are filled accurately and efficiently.

Material Selection Considerations   

• Corrosion Resistance - Given that auger fillers are often used in industries like food and pharmaceuticals, where hygiene is crucial, the materials used in their construction must be resistant to corrosion. Stainless steel (such as 304 or 316 grades) is commonly chosen for its durability and resistance to rust, chemicals, and harsh cleaning processes.
• Non-Reactivity - For applications in the food and pharmaceutical industries, the materials should be non-reactive to ensure that the filler does not contaminate the product. Stainless steel, food-grade plastics, and certain ceramics are often selected for their inert properties.
• Durability and Strength - The auger system, in particular, must be made of materials capable of withstanding continuous operation and handling tough products. Hardened steel or high-strength alloys are often used for the auger and other moving parts to ensure longevity and minimize wear and tear.
• FDA and GMP Compliance - In industries like food, pharmaceuticals, and cosmetics, equipment must comply with regulatory standards such as FDA (Food and Drug Administration) and GMP (Good Manufacturing Practices). Materials used in auger fillers should meet these requirements for safety and cleanliness, ensuring the system can be easily cleaned and sanitized.
• Temperature and Pressure Resistance - For industries dealing with high temperatures or pressurized products, such as chemicals or certain food items, the materials used in the auger fillers must be resistant to thermal expansion and pressure variations. Specialized alloys or heat-resistant coatings may be required for such applications.
• Ease of Maintenance - The materials should be chosen not only for their strength and resistance to wear but also for their ease of maintenance. Smooth, non-porous materials are preferable for easy cleaning and servicing. Parts like augers and filling chambers should be designed for quick disassembly and reassembly to reduce downtime.
• Dust and Contamination Control - In industries dealing with powders, such as food, pharmaceuticals, and chemicals, it’s important to select materials that minimize dust generation and prevent contamination. The use of seals, vacuum systems, and dust collection attachments are important in ensuring the hygiene and safety of the products being filled.
• Compatibility with Filling Materials - Materials used in the machine must be compatible with the specific properties of the substance being filled. For example, powders with different particle sizes or liquids with varying viscosities may require different material properties, such as flexible augers for pasty materials or fine-thread augers for powders.
• Cost Efficiency - While the quality of materials is essential, cost efficiency also plays a role, especially in industries requiring large-scale production. Materials should strike a balance between cost and functionality, ensuring that the auger filler provides reliable performance while remaining within budget.
• Environmental Impact - As sustainability becomes increasingly important in manufacturing, materials that are recyclable or have minimal environmental impact are preferred. Choosing eco-friendly materials, such as recyclable plastics or sustainably sourced metals, can help reduce the carbon footprint of manufacturing processes.
