Possible applications of fine ground sugar


Chocolate / Fillings: <20...30 µm Gap Mill (+ Air Classifier)
Cookies / Confectionary: <100...150 µm Universal Mill / UCOM
Instant Drinks: 100...600 µm Roller Mill


Bauermeister Gap Mills

If a fineness of up to 99 % < 40 µm is required, the Bauermeister Gap Mill is the perfect choice. For extrafine products the Gap Mill can be combined with a classifier to reach up to 99 % < 25 µm. Depending on the mill size and required fineness an output of up to 4,500 kg/h can be reached.

Bauermeister Universal Mills

Standard icing sugar fineness is required for many products such as biscuits, sweets and chewing gum and can be optimally produced on Bauermeister Universal Mills or on the Bauermeister Compact Grinding Plant.

Bauermeister Roller Mills

Bauermeister Roller Mills are recommended for sugar grinding when a relatively coarse particle size (>0.2 mm) in addition to a low amount of fines is required. A popular example is sugar intended for instant drink production.

Sugar Conditioning

Freshly ground icing sugar tends to clump together. Anti-caking agents such as starch or calcium silicate are often added in small amounts to prevent this. If an additive free product is favoured, conditioning is necessary to prevent clumping of the icing sugar. For this purpose, the icing sugar must be heated and moved. The excess moisture released during recrystallization must be removed. This is realized with two heating screw conveyors. The product is then cooled down again using a cooling screw conveyor.

After conditioning, the icing sugar is in a state of equilibrium with the environment and can be stored for a minimum of six months in conventional storage (max. 60 % RH) without clumping.
