Decanter for the food industry DDF series

for the beverage industrycentrifugalhorizontal

Overview
The DDF Series decanter centrifuge is a horizontal, continuous‑operation unit available in 2‑phase or 3‑phase configurations with continuous solids discharge via a scroll conveyor. The dual‑drive arrangement with variable differential speed delivers controlled separation for food and beverage processing applications.

Food & Beverage Industry Applications
The DDF Series is engineered for fruit and vegetable processing, beverage production and by‑product treatment, enabling clarification, dewatering and valorization of process streams.

Key Processing Capabilities

• Juice Clarification — Reduces suspended solids in fruit and vegetable juices to improve clarity and downstream filtration performance.
• Pulp Concentration — Efficient dewatering of pulp and by‑products to increase solids concentration and reduce transport, drying and disposal costs.

Process Advantages
The DDF Series combines effective liquid clarification with high solids dewatering in a single continuous step, improving product quality and operational efficiency while enabling consistent process control.

Hygienic Design & Food Safety
All food‑contact components are manufactured from food‑grade stainless steel and the unit is compatible with CIP systems. Polished contact surfaces and sanitary design minimize product retention and support hygienic operation.

Product Features

• Maximum Performance — High G‑force from a high‑speed rotating bowl for effective solid/liquid separation.
• Flexible Configuration — Choices of construction materials, wear protection, motor power and gearbox torque.
• Touch Panel — PLC with HMI for automatic modes, sludge dryness adjustment, parameter setting and alarm monitoring.
• High Hygiene — Food‑grade materials and lubricants, grooved inner bowl and polished surfaces to reduce product build‑up.
• Product Based Performance — Variable conveyor speed to control solids conveying rate and final dryness.
• Dual Drive — Main motor for the bowl and secondary motor for the conveyor, both VFD‑driven and linked via a high‑torque gearbox without friction clutch.
