With these considerations in mind, tubular cable-drag conveyors are quickly becoming the conveyor of choice for coffee processors due to safe, gentle movement that minimizes dust hazard and product degradation while still offering high throughput. These conveyors provide versatile layouts and can be used to pick up coffee grounds from different sources for transport over long, complex routes to various destinations.

The distances and rate of speed required to move the material are also considerations. Does the conveyor need to pick up from, feed multiple locations, or follow a complex route around other equipment or structures? Are there any special safety considerations based on area classification, traffic, or other processes?

Although enclosed conveyors can be used effectively to convey powders in the food industry, the choice may be dictated by the specific product and size of powder.

However, there can be challenges in conveying these types of ingredients if the powder is sticky, hygroscopic, or tends to cake or pack. Powdered food products and ingredients can also present significant health and safety hazards when they become airborne and are combustible or have explosive properties.

The most critical aspect to consider is the type of product you’re trying to convey. Issues such as product flow, abrasiveness, and cohesiveness should always be considered, whereas product degradation or the need to maintain a blend may be key aspects to consider in some applications.

Flour
Flexible screw conveyors are an ideal choice for flour. The flexible screw conveyor’s only moving part, the spiral, continuously mixes as it conveys. The conveyor can be configured with a drop-out trap, quick-release flanges, and a reverse bung that facilitates hygienic flour conveying when switching between different batches of flour.

Tubular cable-drag conveyors are also enclosed and use cables with discs attached at set intervals within a tube to gently pull powder from inlets to discharges.
