Food Additives and Food Supplements with many different Properties

A large group of polysaccharides and proteins which have a high capacity for gelling are known as hydrocolloids. A large number of these originate from nature most of them from the plant world. However, hydrocolloids can also be obtained from algae, bacteria and animal sources. The extraction of hydrocolloids is carried out using several very different processes and often the products obtained are further modified in order to regulate certain properties.

Hydrocolloids are used in the food industry as gelling- and thickening agents, stabilizers, humectants etc. Furthermore, their properties give each particular food its appearance and the usual (texture) mouth feel.

We can offer you the optimum solution for your requirements with NETZSCH´s proven technology including impact-, classifier-, jet- and fine-grinding mills.

Application Example Pectin

Pectins are plant-based polysaccharides which can be found in all hard plant parts, for example stems, flowers or leaves. Seen from a nutritional point of view pectins provide dietary fiber for humans, although they are used chiefly as gelling agents in the food industry. Pectins are essential ingredients of many products in the food- and pharma industries or are used in the manufacture of cosmetics.

Application Example Algae

Algae not only have a high content of minerals and trace elements, but are also rich in carbohydrates, unsaturated fatty acids and/or beta-carotenes. For this reason algae are interesting as a food – so far predominantly in South East Asia.

For special applications the individual ingredients are used or the degradability of algae is exploited and the products obtained through degradability used.

Application Example Cellulose and Cellulose Derivatives

Before cellulose and cellulose derivatives can be used in pharmaceutical products, a multistage processing is necessary.

With their precise and high number of cuts and the use of a screen insert and/or with a rotating classifier wheel to determine the final size, the fine-grinding mills CS-Z, SecoMy® and SecoMy® S by NETZSCH are an ideal solution for the first processing step. The cellulose powder obtained with these machines can be added straight away to the product (food) as a filler or an additive.

The powder obtained in this way can also be modified and by introducing various functional groups can give a multitude of cellulose derivatives which are characterized by certain particular properties such as solubility, viscosity, gelling power and -temperature or surface activity. With the NETZSCH impact mill the cellulose derivative can be ground down to various finenesses to suit your requirements exactly.

SecoMy® S Fine Cutting Mill

The fast operating fine cutting mills SecoMy® S are the choice for the pulverization of fibrous, ductile, soft, viscoplastic or temperature-sensitive products. In contrast to classic cutting mills, final finenesses of up to 45 μm can be reached in a one-step process with the SecoMy® S

Broyeur sélecteur type CSM

Le sélecteur dynamique à air intégré dans le corps de la chambre de broyage de ce broyeur à impact permet d’obtenir des particules fines avec une limitation de la taille de particule maximale bien définie. La sélection interne des particules grossières procure un procédé plus stable et plus économique en énergie que la sélection en circuit externe. Obtention de finesses de 10 à 150 µm (d97).

Tailles de machines disponibles avec puissances d’entraînement de 1,5 à 250 kW et volume d’air d’environ 50 à 26 000 Nm³/h.

Broyeur à impact Condux®

Le broyeur à impact mécanique ou broyeur centrifuge est habituellement utilisé sous la forme de broyeur à disques à broches, broyeur à rotor soufflant, broyeur à croix percutrice ou broyeur à disques à rainures. De nombreux produits et finesses sur des applications très variées sont traités avec le broyeur universel, qui offre de nombreuses possibilités de combinaisons avec un changement facile des rotors/stators. Obtention de finesses de 30 à 800 µm (d97).

Tailles de machines disponibles avec puissances d’entraînement de 1,1 à 250 kW et volume d’air d’environ 140 à 31 000 Nm³/h.

Broyeur à jets d'air et lit fluidisé type CGS

La combinaison d’un broyeur à jets d’air et d’un sélecteur dynamique à air représente la perfection du broyage fin et sec. Les granulométries finales les plus fines avec une limitation de taille de particule maximale deviennent reproductibles. Le développement des nouveaux systèmes e-Jet® et s-Jet® apporte constamment des nouveaux champs d’applications, avec des avantages aussi bien économiques que technologiques. Obtention de finesses de 1 à 70 µm (d97). Tailles de machines disponibles pour des volumes d’air de broyage d’environ 50 à 12 000 Nm³/h.
