By eliminating internal bearings, hangers, and crevices where material can lodge, easy-clean conveyors leave no blind spots for bacterial growth or residual powders. Regular wash-downs completely sanitize the smooth stainless steel contact surfaces, making them fully compliant with strict Australian sanitary standards for food, dairy, and pharmaceuticals.

An easy-clean flexible screw conveyor is engineered with a quick-release end cap and a heavy-duty U-bolt assembly. This specialized setup allows machine operators to fully uncouple and pull out the inner coreless screw auger straight from the bottom end of the unit. The entire food-grade tube can then be flushed and fully sanitized without requiring any special tools or ladders, dropping batch changeover cleaning times down to under 5 minutes.

The main difference is the housing and routing flexibility:

·  Flexible Screw Conveyor (FSC): Uses a flexible or rigid plastic tube (or casing) and runs at low speed. The lack of internal bearings allows it to bend around fixed obstacles and convey at steep inclines more than 45 degrees.

·  Rigid Screw Conveyor (Auger): Uses a fixed metal trough or casing with internal bearings. It is limited to straight line transfers (horizontal or shallow incline, typically max. 25 degrees).

The primary limitation is its gentle handling capability compared to other conveyors. Since the helix pushes and tumbles the material, it is not ideal for highly fragile or friable materials (like certain delicate cereals or snack foods) that may break down or suffer degradation during transfer.

A flexible screw conveyor (also known as a helix conveyor or screw auger) is a simple, mechanical conveying system that uses a rotating helical spiral inside a stationary, flexible or rigid tube. The spiral pulls the material along its length, allowing the conveyor to move product with higher inclined angle more than 45 Degrees.

The key benefits include:

Easy to clean: Conveyors are often designed to disassemble quickly (e.g., in 5 minutes) for thorough wash-down and sanitation.

Simple Design & Low Maintenance: A single helicoid screw rotates inside a fixed tube, requiring only fewer components and a single drive point, which minimizes maintenance needs.

Long distance & Height: These conveyors can convey materials over distances up to 80 ft (24.4 m) and achieve discharge heights up to 40 ft (12.2 m)

Cost-Effective: They are generally a lower-cost option compared to complex pneumatic or bucket elevator systems.
