Food-Grade Screw Conveyors

Custom-Built | Manufactured to Meet Customer Sanitation Protocols | High Wear Resistance

Precision Machine & Manufacturing’s stainless steel screw conveyors are engineered to deliver reliable, sanitary bulk material handling for demanding food processing applications, and are manufactured to meet and/or match customer specific sanitation protocols. Manufactured from 304/316 stainless steel, every screw conveyor is purpose-built to achieve the specific requirements of the application including the material characteristics, throughput, and operational environment. The result is a durable, hygienic conveying solution delivering exceptional reliability, long service life, and superior performance.

Key Features:

  • Purpose-Built Performance: Custom-engineered for your specific food product, process, and throughput—never off-the-shelf or one-size-fits-all.

  • Wide Range of Sizes and Configurations: All designs, sizes and configurations are 100% based on the application and are manufactured to meet customer sanitation protocols.

  • Exceptional Wear Life & Process Options: Constructed from 304 and/or 316 stainless steel for durability and food safety. Available options include dewatering, mixing, drying, breaker bars, cut or folded flights, and additional wear protection in high-impact zones.

  • Made in the USA & Maximum Durability: Every screw conveyor is handcrafted in the USA! The heavy-duty design minimizes maintenance and reduces downtime

  • Rebuildable: All PMM screw conveyors are rebuildable, significantly lowering lifecycle costs.

When food safety, sanitation, and performance matter most, PMM’s heavy-duty, food-grade screw conveyors deliver where standard augers fall short—providing reliable, hygienic operation with reduced wear and maintenance.
