Bead Mills / Mixers / Deaerators

Ball mills, nano mills, in-line mixers, planetary mixers, vertical disk mill, basket mills, degassers, dissolvers – these are the facilities that have won approval of GRUPA WOLFF’s customers. They distinguish themselves in the market through high standards of workmanship, reliability and a long service life.

Chocolate production lines are a separate segment of that part of our offer. We are proud of a number of a number of successful installations at large confectioneries in Poland.

We offer a selection of a proper device, installation works in a full extent, commissioning and service of the already installed equipment. Our offer also includes original spare parts for the equipment sold.

1. WET GRINDING

Depending on application and the required final fineness of grinding, we may offer various mills, including those milling to nanoparticles. Both the horizontal mill and the vertical one mill consist of a milling chamber filled with grinding media which crumble the product through collisions with product particles. The movement of grinding media is generated through a rotating mixer shaft with additional elements intensifying the milling process (disk with various shapes, pins). Additionally, the mill is equipped with a properly designed separator that set apart grinding media from the product living the milling chamber. The horizontal mill ensures a uniform distribution of grinding media in the milling chamber and thereby improves the milling process quality.

For milling frequently changed products, we recommend the basket mill which is operated in a periodically recurrent mode. Grinding media are closed in a basket immersed in a tub with a product. Once the process is completed, a tab with a new production batch (new product) can be placed.

2. MIXING AND DISPERSION

Depending the product viscosity and characteristics, we can offer you various machines for mixing and dispersion. The most popular of them is a dissolver which is intended for dispergation of powders in fluids. There is a dispersing disk mounted on a mixer shaft. One can regulate the disk speed and the height at which it is immersed in the tub. In the standard version, the mixing and dispersion process is conducted in mobile tubs; for larger batches (over 1000 litres), we offer innovative stationary dissolvers in case of which a separation of mixing and dispersing functions results in a significant reduction of power consumption.

We recommend the in-line mixer especially for products with high a content of solid particles, low content of solid particles in a large liquid volume and those containing wetted solid particles. Depending on the product characteristics, the product batch size for the in-line mixer is 100 to 15000 L (for the laboratory device: 15 to 300 L).

The planetary mixer is intended for mixing high viscosity products (up to 10000 Pas) and products particularly sensitive to high temperature. Different mixers ensure delicate mixing of products. It is available in two versions: high-speed (a combination of al low-speed mixer and a high-speed one) and low-speed (with two low-speed mixers).

3. VACUUM DEGASSERS

The Netzsch vacuum degasser is intended for removing air (gases) form the product and thereby, for improving its quality and durability. The machine operates on the principle of rotation of a thin layer of the product and may be applied for different types of products. Depending on the product viscosity, the degasser capacity may be 50 to 4000 kg/h (for the laboratory device: 20 to 200 kg/h). The deaerator may be operated in a periodically recurrent mode or, at greater efficiencies, it may be included into a production line and operate continuously.

4. LINES FOR PRODUCTION OF CHOCOLATE AND CHOCOLATE MASSES

The chocolate production process consists of the following stages: raw materials preparation (initial grinding of sugar, melting of cocoa pulp and cocoa butter), dry and wet conging process and refinement (grinding of chocolate mass).

An innovative conge allows to apply a smaller amount of fat in the dry conging process and thereby to shorten the production process and reduce power consumption. Due to the equipment compact design, it is easy to increase the system productivity through purchasing subsequent equipment modules. The smallest chocolate production line is operated periodically and the production lot size is 25 – 50 kg.

The production of chocolate masses (fillings, toppings, creams for bakery products) proceeds analogously a chocolate production with the only difference that there is no dry or wet conging process due to a higher vegetable fat content in the product.

  • Chocolate topping production line
  • Chocolate-like mass production line
