What is a Stainless Steel U Trough Screw Conveyor?
Our Stainless Steel U-Trough Screw Conveyors are engineered to deliver highly efficient, reliable, and hygienic bulk material handling solutions. Designed with a modular U-shaped trough and fully removable bolted or quick-clamping covers, these conveyors offer unparalleled accessibility for thorough cleaning and routine maintenance.
Fabricated from premium-grade SUS304 or SUS316L stainless steel, they feature smooth, high-polish finishes that prevent material build-up and cross-contamination. This makes them the industry-standard choice for strict sanitary environments, including food processing, pharmaceuticals, cosmetics, and corrosive chemical industries. Whether you are conveying sticky powders, granular food ingredients, or aggressive chemicals, our U-trough design ensures dust-tight, safe, and continuous operation.
What are advantages of Stainless Steel U-Trough Screw Conveyors？
This premium product series features high-grade stainless steel construction with a finely polished finish that eliminates material accumulation and complies with strict sanitary standards. Equipped with quick-release removable covers, the equipment ensures effortless sanitation and streamlined maintenance. Its superior resistance to corrosion and abrasion guarantees an extended service life when handling aggressive or high-moisture materials. Furthermore, the integration of high-performance sealing gaskets achieves completely enclosed, dust-free performance, preventing environmental contamination and leakage entirely.
Premium Sanitary Grades:Constructed with optional SS304 or SS316L stainless steel featuring a fine polished finish. The smooth surface eliminates material accumulation and dead corners, fully meeting FDA and GMP sanitary compliance standards.
Removable Covers for Effortless Sanitation:Sealed lids fitted with quick-release clamps are installed on top of the U-trough, streamlining routine washdown and maintenance procedures significantly.
Superior Corrosion & Abrasion Resistance:Engineered to handle highly acidic, alkaline, high-moisture materials and juicy food products. Its service life is several times longer than carbon steel alternatives.
Zero Dust Leakage Performance:High-quality silicone and EPDM sealing gaskets are equipped to achieve fully enclosed conveying, avoiding material contamination and dust escape entirely.

Furthermore, the high-performance sealing system provides a completely enclosed, dust-free operation, eliminating material leakage and environmental contamination entirely.
Factory-Direct Pricing:Eliminate middlemen markups and trade companies. As a genuine source manufacturer, Dahan Machine provides high-quality stainless steel U-trough screw conveyors directly from our factory floor, ensuring the most competitive pricing and maximum cost-efficiency for your project.
Free Engineering Support & CAD Drawings:Our professional engineering team can provide customized 24-hour engineering support. Simply share your factory layout and material characteristics, and we will deliver complimentary CAD and 3D technical drawings tailored perfectly to your existing production line.
Advanced Surface Treatment & Precision Welding:For high-sanitary applications, we employ advanced TIG welding and rigorous pickling and passivation (or mirror polishing) treatments. This ensures all stainless steel surfaces are seamless, free of burrs, and dead-zone-free, preventing material contamination and residue buildup.
Rigorous Quality Inspection Before Shipping:Quality is our lifeline. Every single conveyor undergoes a mandatory 2-hour no-load trial run, dynamic balance testing, and noise checks before leaving our factory. All equipment is fully certified with CE and ISO9001 quality management standards to guarantee flawless on-site performance.
Frequently Asked Questions About U-Trough Screw Conveyors
Q1: What is the difference between a U-trough and a tubular screw conveyor?
A1: A U-trough conveyor has a removable top cover, making it extremely easy to open, clean, and inspect. A tubular conveyor is completely sealed by nature and better suited for steep inclinations or higher pressure operations.
Q2: Which stainless steel grade should I choose, SS304 or SS316L?
A2: SS304 is excellent for standard food applications and mild chemicals. If you are handling highly corrosive materials (like sea salt or strong acids) or require strict pharmaceutical standards, SS316L is recommended.
Q3: Can these conveyors handle sticky or wet materials?
A3: Yes, but for sticky materials, we recommend using a Shaftless U-trough screw conveyor to prevent material build-up and clogging on the central shaft.
