Fine grinding and homogeneous mixing of nuts, seeds or beans in a PUC colloid mill

The Probst und Class colloid mill is often used for grinding peanuts, almonds, sunflower seeds, soybeans, or for the production of peanut butter
The production process is very simple: The seeds are introduced through a funnel into the vertical colloid mill, which grinds the nuts or seeds into a homogeneous pasty product.
In the production of Peanut Butter, the nuts go dry in the grinder and the fine butter comes out at the bottom. With other kinds of nuts that contain less oil, extra oil is sometimes added. The PUC Colloid mill simply distributes the oil homogeneously in the butter and creates a fine paste.
Even when extra ingredients have to be added to the product, this is no problem.

In the food industry, PUC mills are also used for the production of sauces, toppings and pastes. In other industries, products like animal feed, chemical pastes, grease and pigments are good examples of applications for these robust mills.
