droogverstrooiingsmodule

Droogverstrooiingsmodule is a term used in Dutch technical literature to describe a modular device designed to disperse dry particulate matter into a process stream or environment in a controlled manner. The word combines droog (dry) with verstrooiingsmodule (dispersion module).

Purpose and function: The module provides precise control of the feed rate and spatial distribution of powders, supporting uniform coating, mixing, or downstream processing while minimizing agglomeration, bridging, and excessive dust generation.

Design and components: A typical droogverstrooiingsmodule includes a hopper or reservoir, a metering feeder (such as a screw, rotary vane, or diaphragm feeder), a dispersion head or nozzle, and an enclosure with sensors and a control unit. An optional air assist line can enhance dispersion. Materials are chosen for compatibility with the conveyed powder, with stainless steel and engineered polymers common choices.

Operating modes and integration: It can be fed by gravity, vibratory feeders, or screw feeders, and may use pneumatic or mechanical dispersion methods. The module is commonly integrated into packaging lines, coating or drying systems, and other process plants, often connected to a process control system for real-time adjustments of flow and distribution.

Safety and standards: Dry powder handling introduces dust and explosion hazards, so design considerations include dust containment, electrical grounding, proper sealing, and compliance with applicable standards and directives (such as ATEX in Europe) where relevant.
