Ingredient Feeding & Conveying
Inclined Auger Conveyors by A.I.S. lead the industry in efficiency, not just efficiency of transporting material & ingredients, but efficiency in cleaning & maintenance also, creating the ability to increase production and decrease down time.
In modern food, pharmaceutical, chemical, and industrial processing facilities, the efficient movement of ingredients between processing steps is critical. Inclined auger conveyors—also known as inclined screw conveyors—provide a reliable and sanitary method for transporting powders, granules, and bulk ingredients from one elevation to another within a production line.
AIS Inclined Auger Conveyors are engineered to deliver consistent ingredient flow while minimizing plant footprint, reducing dust, and ensuring accurate feeding into mixers, packaging equipment, storage bins, and processing systems.
Designed for durability and ease of operation, AIS conveyors also feature advanced sanitary options including an Easy-Clean removable screw design and optional CIP (Clean-In-Place) systems for fast and efficient cleaning.
An inclined auger conveyor is a mechanical conveying system that uses a rotating helical screw (called an auger) housed within a tube or trough to move bulk materials along an inclined path. As the screw rotates, it pushes material forward through the conveyor until it reaches the discharge point.
These conveyors are widely used across many industries because they can transport powders, pellets, grains, and other bulk materials in a controlled and enclosed system. Their compact design allows them to elevate ingredients without requiring additional lifting equipment such as bucket elevators or pneumatic conveying systems.
Inclined auger conveyors typically operate at angles up to approximately 45 degrees from horizontal, allowing facilities to move materials between different process elevations while maintaining a small equipment footprint.
The operating principle behind an inclined auger conveyor is simple yet highly effective. A rotating spiral flight mounted on a central shaft moves material through a tubular housing.
The process typically follows these steps:
Bulk ingredients are introduced into the conveyor through a hopper or feeding system.
A motor-driven auger rotates inside the conveyor tube.
The rotating screw pushes the material upward along the incline.
Material is discharged into the next stage of the process, such as a mixer, silo, feeder, or packaging machine.
Because the system is enclosed, it helps contain dust, reduce product contamination, and maintain sanitary processing conditions—making it ideal for food, pharmaceutical, and nutraceutical applications.
Inclined auger conveyors offer numerous advantages for ingredient handling systems and powder processing operations.
Inclined conveyors allow manufacturers to move materials vertically without requiring large elevators or multi-level conveyor systems, reducing plant footprint and simplifying facility layout.
By adjusting the screw speed, operators can precisely regulate the material flow rate, allowing the conveyor to function as both a transport system and a metered feeder for downstream processes.
The enclosed tube design prevents ingredient loss, minimizes dust emissions, and helps maintain hygienic processing conditions.
With relatively few moving parts and simple mechanical design, auger conveyors offer dependable operation and low maintenance requirements compared to many alternative conveying technologies.
For industries where sanitation and rapid product changeover are critical, AIS offers an Easy-Clean inclined auger conveyor option.
This design allows the screw to be quickly removed from the conveyor tube for manual inspection and cleaning. Operators can easily access internal components without complicated disassembly, significantly reducing downtime during sanitation procedures.
The Easy-Clean feature is especially valuable for facilities producing:
Food ingredients
Nutraceutical powders
Pharmaceutical materials
Flavorings and spices
Specialty chemicals
By simplifying cleaning procedures, this design helps manufacturers meet strict hygiene standards while maintaining high production uptime.
AIS inclined auger conveyors can also be supplied with a Clean-In-Place (CIP) system for automated sanitation.
CIP systems use strategically positioned spray nozzles inside the conveyor housing to wash the internal surfaces with cleaning solutions or water without requiring the system to be disassembled.
Benefits of CIP conveying systems include:
Faster sanitation cycles
Reduced labor requirements
Improved hygiene and compliance
Consistent cleaning results
Minimal production downtime
This option is widely used in food, pharmaceutical, and nutraceutical processing environments where frequent cleaning and regulatory compliance are essential.
AIS inclined auger conveyors are widely used in ingredient handling and bulk material processing systems.
Typical applications include:
Feeding mixers with powders or granular ingredients
Elevating materials from bag dump stations or bulk bag unloaders
Conveying powders from mills, sifters, or grinders
Transferring ingredients to storage silos or intermediate bins
Feeding packaging machines and filling systems
Metering ingredients into batching or dosing systems
These systems are commonly used to convey materials such as flour, sugar, spices, protein powders, additives, grains, salts, chemical powders, and mineral ingredients.
AIS designs inclined auger conveyors to integrate seamlessly with complete ingredient handling systems. Each conveyor can be engineered to meet the specific requirements of your facility, including capacity, product characteristics, sanitation requirements, and plant layout.
Customization options may include:
Tubular or U-trough conveyor designs
Variable speed drives for accurate feeding
Sanitary stainless steel construction
Washdown or food-grade designs
Easy-Clean removable screw design
CIP (Clean-In-Place) sanitation systems
Multiple inlet and discharge configurations
Integrated hoppers and feeders
Skid-mounted systems for turnkey installation
AIS Inclined Auger Conveyors are often used as part of a complete ingredient feeding and conveying solution. These systems can integrate with:
Bag dump stations
Bulk bag unloaders
Loss-in-weight feeders
Rotary sifters and screeners
Storage bins and silos
Industrial mixers
Automated batching systems
By combining these technologies, AIS helps manufacturers create efficient, automated ingredient handling systems that reduce labor, improve accuracy, and increase production throughput.
