Hydrocolloids

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.

Pectin

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

Molino clasificador CSM

Este molino de impacto cuenta con un clasificador dinámico por aire, integrado en la cámara de molienda, que permite la producción de partículas finas con un tamaño máximo definido y limitado. Gracias al proceso de clasificación interna de las partículas gruesas, se consigue un proceso más eficiente desde el punto de vista energético y de estabilidad, si se compara con un sistema con circuito de clasificación externo. Se emplea para finuras desde 10 a 150 µm (d97).

Tamaños de máquina desde 1.5 a 250 kW y volúmenes de aire de aprox. 50 - 26.000 Nm³/h.

Molino de impacto Condux®

El molino fino de impacto o molino centrífugo normalmente trabaja con las siguientes configuraciones: molino de disco con pins, de palas, de alas batidoras o molino con disco ranurado. Con el molino Universal se pueden procesar un amplio rango de productos y finuras, combinando y cambiando fácilmente distintos rotor y estátors. Se usa para finuras desde 30 a 800 µm (d97).

Tamaños de máquina desde 1,1 - 250 kW y volúmenes de aire de aprox. 140 - 31.000 Nm³/h.

Molino Jet de lecho fluidizado CGS

La combinación de un molino jet y un clasificador dinámico por aire, da como resultado una perfecta molienda en vía seca. Es posible alcanzar y reproducir la finura final deseada dentro de unos límites exactos de tamaño de partícula. El desarrollo de los nuevos e-Jet® y s-Jet®, está abriendo nuevos campos de aplicación, hasta ahora vedados a la molienda por chorro de aire, por razones económicas o técnicas. Es aplicable para finuras desde 1 a 70 µm (d97).

Tamaños de máquinas disponibles para volúmenes de aire de molienda desde aprox. 50 a 12.000 Nm³/h.
