Refines and Grinds Cocoa and Chocolate Products
The CAO 2000 from Caotech is a low-speed, agitated-type ball mill designed specifically for the fine grinding of cocoa liquor and chocolate mixtures. This equipment stands out for its reliable performance in processing challenging materials such as creams, bread spreads, and fat-based compounds. Capable of integrating with mixers and refiner conches, it supports versatile production lines for batch operations in the food and confectionery industries.
With a capacity of up to 2,000 kg/h for cocoa liquor and up to 1,000 kg/h for chocolate using powdered sugar, the CAO 2000 meets diverse production needs. Its direct drive design ensures energy efficiency and minimal heat development, reducing operational costs and maintaining product quality. Constructed to require no special foundation, it offers ease of installation and low maintenance demands.
Ideal for applications in chocolate manufacturing, bakery, and dairy facilities, the mill ensures consistent end-fineness, up to 99.9% through a 75-micron sieve, contributing to the production of high-quality chocolate bars, praline fillings, and compound coatings. Hands-on engineering support and custom configurations are available to suit specific operational requirements, making it a valuable asset in optimizing your processing plant’s efficiency.
