Skid for the production of icing sugar

Processed product: crystal sugar / icing sugar 

Preparation of food mixtures 

Food processing company involved in the preparation of food mixes in powder form.

Our customer processes four tons of icing sugar daily for the preparation of its final recipes. Historically supplied with icing sugar, the client decided to entrust Palamatic Process with the realization of a skid for the production of icing sugar. This icing sugar production unit is composed of a bulk bag loader, dosing screw, pin mill, buffer hopper and a bag/drum filling station.
The handling of the bulk bags is carried out by the operator via a stacker. Handling bulk bags at the inlet of the production line provides less operator intervention compared to equipment using 50 lb sacks.
The bulk bag discharge and its feeding screw ensure volumetric dosing of the crystal sugar at the mill inlet. Given the explosive nature of sugar, the whole line is designed to meet the hazardous area classification. A flame barrier rotary airlock, as well as slam shut valves and explosion vents ensure the safety of the grinding line. The plant is approved to ATEX 20 standard and regulations.

The Palamatic Process Model UM 500 pin mill is located in the production area where incoming air is dehumidified and temperature controlled which are important factors for providing high quality milling results. The process of milling sugar, or any other type of powder, causes the product temperature to rise. This can strongly impact the behaviour of the powder even resulting in melting the material.
Similarly, during the powder grinding operation, moisture can be released when the grain is "broken/ground". This released moisture must be absorbed by dry processed air in order to avoid any risk of caking. In the case of sugar, a threshing hopper ensures the gradual cooling of the product and pass through air picks up the released moisture .  
The buffer hopper is made of mirror-polished stainless steel with injection of fresh and dry air. The bagging unit allows the operator to pack bags of icing sugar at the exact weight required by the production line recipe sheets. Therefore this sugar grinding plant provides a safe and on-demand production of icing sugar for the whole production plant.
