Automatic chocolate processing line
Transform your production by automating the complete chocolate-making process—from precise ingredient weighing to fine grinding—ensuring consistent quality for a variety of delicious chocolate and spread products.

Processes Chocolate and Compound Coatings Continuously
The CAO 3000[2]-CHOC IN-LINE from Caotech is a fully automatic production line designed to simplify the complexity of chocolate and fat-based compound manufacturing. This system is distinguished by its integration of two low-speed agitated ball mills and a Mini Mix unit, enabling PLC-controlled weighing, mixing, conching, and fine grinding. Ideal for producing chocolate bars, spreads, and coatings, it boasts a processing capacity of up to 1,500 kg/h using crystal sugar. It offers energy-efficient operations with low heat development, reducing maintenance time and ensuring constant product quality. Its compact design requires minimal floor space and no foundation, enhancing adaptability in various production settings. Additionally, automatic feeding systems for ingredients such as fats, lecithin, and aromas streamline the continuous production process.
