Chocolate and Confectionary

Rospen’s specialist weighing, metering and materials handling systems help manufacturers dose cocoa powders, sugars, inclusions and coatings with high accuracy, from small additions through to large-scale continuous processes. 

Value‑Added Chocolate, Reliably Delivered

Do you need to produce a wide range of chocolate bars, pralines, enrobed snacks or sugar confectionery on the same line, without compromising on accuracy? Rospen designs and supplies automated ingredient handling and feed systems that support rapid recipe changeovers while maintaining tight tolerances on every component.

• High‑accuracy loss‑in‑weight and continuous feeders for powders, granules and flakes, including cocoa, sugar, milk powders and starches.
• Proven solutions for dosing fragile or irregular inclusions such as nuts, cereal pieces, fruit, crisps and other particulates without excessive breakage.
• Centralised control and recipe management via PLC or PC/PLC systems, with full batch and traceability data available for QA and compliance.

From Raw Ingredients to Finished Mass: Cocoa, Sugar and Base Ingredient Handling

Whether you are handling bulk cocoa powder, icing sugar or minor ingredients, accurate and dust‑tight handling is essential for hygiene, safety and product quality. Rospen provides complete solutions from bulk intake through to process feed points.

• Silo and bulk bag systems for flour, sugar and cocoa, including ATEX‑compliant designs for Zone 20 and 21 environments where combustible dusts are present.
• Pneumatic and mechanical conveying options engineered to minimise degradation of fragile ingredients and to control dust emissions at transfer points.
• Integrated sieving, screening and conditioning to ensure a consistent feed to mixers, refiners and conches.

Gentle Handling of Fragile Confectionery Products

Chocolate and confectionery products often include delicate inclusions or formed pieces that can be easily damaged during handling. Drawing on decades of experience with particulates, granules, flakes and crisps, Rospen designs systems that preserve product integrity.

• Weigh belts, vibratory feeders and bespoke transfer solutions for friable and fragile products such as coated nuts, cereal clusters and aerated pieces.
• Vacuum and low‑velocity conveying configurations to reduce impact and abrasion, helping retain shape and appearance on finished products.
• Hygienic designs with easy access for cleaning and changeover to support allergen control and reduce downtime between products.

Accurate Feeding For Continuous And Batch Lines

Modern chocolate and confectionery plants increasingly rely on continuous processes for consistency and efficiency. Rospen’s weighing and feeding technologies integrate seamlessly with mixers, refiners, cookers, coating and enrobing lines.

• Continuous weighers, enclosed weigh screws, and weigh belts for real‑time mass flow measurement and control.
• Precision loss‑in‑weight feeders for minor and micro‑ingredients, ensuring stable feed to continuous mixers and cookers.
• Mixer weighing and batching systems that provide high‑accuracy dosing, recipe control and automated reporting for audits.

Built For Hygiene, Safety and Long‑Term Performance

Food safety, dust control and repeatable accuracy are critical in chocolate and confectionery manufacturing. Rospen designs and supplies complete systems that support your operational, quality and regulatory requirements over the full lifecycle.

• Designs aligned with food industry hygiene expectations, including smooth contact surfaces, appropriate finishes and options for CIP‑friendly layouts.
• ATEX‑rated equipment and systems where required, covering storage, conveying and dosing of combustible powders.
• End‑to‑end service covering system design, build, software, commissioning, training and ongoing support from an experienced in‑house team.
