Direct discharge descender for product handling
Efficiently transport granulated materials without compromising their integrity, ensuring consistent flow rates and seamless integration into your existing production line.

Conveys and Discharges Granular Products Safely
The DED – Direct Discharge Descender from GEA is engineered to deliver seamless product transfer within food, beverage, and pharmaceutical manufacturing settings. This equipment’s continuous-section monolithic spiral, crafted entirely from stainless steel, facilitates efficient and gentle transport of granules, powders, and pellets directly to packaging or subsequent processing stages. The design prevents product degradation by eliminating joints and maintaining a constant speed descent, which is crucial for preserving the integrity of delicate materials like dairy creamers and confectionery bits.
Supporting a variety of products such as protein powders, detergent granules, and pharmaceutical tablets, the DED assures smooth integration within existing production lines. It is particularly suitable for industries needing precise handling to avoid cross-contamination or product damage. The spiral’s diameter is tailored to specific capacity needs, and optional features like rotating product outlets and gate valves enhance operational flexibility.
GEA’s descender also addresses energy efficiency with its innovative spiral support arms designed to prevent product clogging, thereby minimizing downtime. A polycarbonate cover runs the length of the descender, offering protection and containment. Compliance with industry standards ensures suitability in diverse applications, making the DED a versatile choice for manufacturers focused on maintaining high-quality outputs.
