Food-Grade Screw Conveyors

Custom-Built | FDA & USDA Compliant | High Wear Resistance

Precision Machine & Manufacturing’s food-grade screw conveyors are custom engineered to deliver reliable, sanitary bulk material handling for demanding food processing applications. Designed to outperform industry-standard augers, our systems are built to meet exact throughput requirements while maintaining strict food safety and sanitation standards. Manufactured from 304 or 316 stainless steel, each conveyor is purpose-built to match your specific material characteristics, capacity requirements, and processing environment. The result is a durable, hygienic conveying solution that delivers exceptional reliability, long service life, and consistent 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: FDA- and USDA-compliant designs including screw augers, split-tube, tubular, and U-trough conveyors, along with sanitary tubular feeders featuring food-grade shaft seals and hygienic hopper designs for washdown environments

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

  • Built-to-Order Manufacturing & Fully Customizable: Every screw conveyor system is handcrafted in the USA and fully customized—no two augers are the same, unless required.

  • Maximum Uptime: Heavy-duty design minimizes maintenance, reduces downtime, and extends service intervals.

  • Flexible & Scalable: Modular construction with application-specific auger geometry and pitch ensures optimal flow rates for low- to high-volume food processing operations.

  • Rebuildable: All PMM screw conveyors are rebuildable, significantly lowering lifecycle costs. Most customers achieve 3–4 rebuilds per auger.

  • Broad Size Range & System Capability: From compact enclosed tubular feeders to 50-foot multi-screw conveying and mixing systems, PMM delivers solutions for the most challenging food-grade applications.

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.
