Dry milling and classification of sugar

The POITTEMILL Group offers a wide range of products for sugar, biscuits and confectionery.

Sugar is a sweet-tasting substance extracted mainly from sugar cane or sugar beet. It is an important component of our daily carbohydrate intake. Important industrial properties of food products containing sugar are flow properties, appearance, solubility, dust content and taste.

Depending on the level of purity required, sugar is clarified and crystallised repeatedly. In addition to coarse sugar, crystal sugar, used in domestic and industrial applications, requires the finest form of sugar, e.g. powdered sugar. This fine sugar is obtained by mechanically grinding crystal sugar with modern impact mills.

Our decades of experience combined with a sophisticated technology offering for applications in the processing stages of dry grinding and high-performance classification, as well as the proximity to our customers, lead to the design of machines that meet the standards of today and tomorrow.


Sustainable process solutions

Fully integrated solutions are the key to providing optimised processes that help you both reduce costs and make more sustainable use of valuable resources.

These systems are based on the principle of:
• Reliability and safety.
• Low operating and maintenance costs.
• Guaranteed hygienic, customer-oriented process solutions.
• Easy cleaning.
• Energy saving.

The diverse characteristics of powders in these types of industries require a combination of engineering skills and experience to design quality systems to meet the expectations of today’s and tomorrow’s customers.


Process testing and development

The POITTEMILL Group has its own scientific laboratory as well as a test center which is unique in France. It is in this test center that the dialogue between customers and the technical teams begins, but it is also here that detailed analyses of their raw materials are carried out in order to obtain complete information on the execution of the task set.

Our development and engineering team is always available to help you explore new and innovative processes and applications.

Our testing facilities offer exceptional opportunities to test ingredients, machines, parameters, and processes, whether in the laboratory, pilot or industrial scale, to ensure you achieve the necessary product quality and operating efficiency.
