Cocoa powder is a fine, hygroscopic, and cohesive bulk material used in bakery, confectionery, beverage, and dairy production. A well-designed pneumatic conveying solution moves it safely from storage, sieving, mixing, or packing areas while preventing contamination, dust leakage, and product degradation. Our custom systems match your capacity, plant layout, process conditions, and food safety requirements.

We design complete cocoa powder conveying systems based on a detailed analysis of particle size, bulk density, moisture, flowability, and abrasiveness. This information determines the correct pipeline diameter, air velocity, pressure, filter area, and feeding device. The result is stable, continuous, and gentle transfer with minimal degradation and no dust escape.

Depending on your process, we provide dilute phase and dense phase pneumatic conveying. Dilute phase uses higher air velocity and is appropriate for short to medium distances. Dense phase uses low velocity and high pressure to push plugs of cocoa powder gently through the pipe, reducing energy use, degradation, and pipe wear on longer layouts.

Our vacuum conveying systems are excellent for bag dumping, silo discharge, and feeding packaging lines. Negative pressure keeps dust inside the pipe and allows multiple pickup points. Positive pressure systems move large volumes over longer distances and use rotary airlocks, diverters, filters, and receivers to feed several production lines automatically.

All product contact components are manufactured from stainless steel with food-grade surface finishes. The system typically includes a receiving hopper, rotary airlock, blower, filter receiver, pulse-jet dust collector, level sensors, pressure transmitters, valves, and a control panel. Gaskets and seals are selected for food contact compliance and can be cleaned easily during changeovers.

Since cocoa powder is a combustible dust, safety is a core part of our design. Earthing, bonding, explosion venting, suppression, and isolation devices are supplied where required by a dust explosion risk assessment. Pressure monitoring, filter differential pressure checks, overpressure protection, and automatic shutdown controls protect personnel and equipment.

Modern systems use PLC and HMI controls to manage start-up, air flow, filter cleaning, material level, discharge sequence, and alarms. Communication with plant management software allows real-time monitoring of conveying rate, energy consumption, and maintenance alerts. Automated operation improves consistency, traceability, and overall production efficiency.

With a pneumatic conveying system, you eliminate manual scooping, reduce labor costs, increase capacity, and protect operators from dust. Closed pipe transport prevents contamination, preserves moisture balance, and provides consistent feeding to mixers, molds, and packing machines. Compact pipe routes free floor space and allow flexible routing around existing equipment.

Our systems are used for dosing cocoa powder into chocolate mass, cocoa beverages, bakery premixes, dairy drinks, ice cream mixes, and confectionery products. We handle natural and alkalized cocoa, low-fat and high-fat grades, and blended fine powders. Conveying parameters are adjusted to avoid caking, fat migration, segregation, and flavor contamination between batches.

Every conveying line is treated as a custom project. We consider line length, number of pickup and discharge points, height, available space, utilities, and future expansion. We assemble and test the system before delivery, provide layout and electrical documentation, and support installation, commissioning, and operator training.
