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

Moinho Classificador Modelo CSM

O classificador de ar dinâmico integrado na carcaça da câmara de moagem deste moinho de impacto, fabrica tamanhos de partículas finas com uma limitação da definição máxima dos tamanhos. A classificação interna de partículas mais grossas, resulta em um processo mais estável e econômico do que um moinho com circuito externo de classificação. Fineza aplicável entre 10 e 150 µm (d97). Tamanhos com capacidades entre 1.5 - 250 kW e volume de ar de aproximadamente 50 - 26,000 Nm³/h.

Moinho de Impacto Condux®

O moinho de impacto mecânico ou moinho centrífugo é normalmente operado na forma de um disco de moagem com pinos, moinho de rotor de pás ou disco ranhurado. Muitos produtos e finezas para uma ampla variedade de aplicações são processados com o moinho universal, com várias combinações de rotores e estatores que podem ser facilmente trocados. Apropriado para finezas entre 30 a 800 µm (d97).

Tamanhos com capacidade entre 1.1 - 250 kW e volume de ar de aproximadamente 140 - 31,000 Nm³/h.

Moinho de Jatos CGS

A combinação de um moinho de jatos e um classificador dinâmico a ar, representam moagem fina a seco em perfeição. A mais alta fineza com uma limitação exata de tamanho de partícula se torna reprodutível. O desenvolvimento dos novos métodos de moagem e-Jet® e s-Jet® de produção constante, interessam diferentes áreas de aplicação, tanto economicamente quanto tecnicamente. Apropriado para finezas entre 1 a 70 µm (d97). Os tamanhos de equipamentos para moagem a ar em volumes de aproximadamente 50 a 12,000 Nm³/h.
