Laboratory winnowing system for cocoa beans
In the production of high-quality chocolate, one of the critical steps is the accurate separation of cocoa nibs from shells after the beans have been roasted. Inefficiency at this stage can lead to a lower yield and increased waste, directly impacting overall production quality and cost.
Crush and separate cocoa beans precisely
The LAB Winnower from Bühler is designed to handle the demanding requirements of cocoa bean processing. This compact and effective system crushes cocoa beans and separates the shells from the nibs with exceptional precision through sieving and air classification. Equipped with a frequency-controlled crusher, the LAB Winnower ensures maximum yield by matching crushing intensity to different bean characteristics, thus producing a low volume of fines. The adjustable air classification process further enhances product quality by enabling precise control over the separation of nibs and shells. With a throughput capacity of up to 150 kg/h, the system allows for continuous quality analysis and control by taking samples from each sieve deck. Additionally, the LAB Winnower’s closed design minimizes dust pollution, ensuring a hygienic processing environment that meets high food safety standards through its fully stainless steel processing zone.
