Filtration of gelatine with ceramic membranes 

Gelatine is commonly used as a gelling agent in food, pharmaceuticals, photography and cosmetic manufacturing. And it is found in grocery store products like gummy sweets, yoghurt, marshmallows, gelatine desserts, and some ice creams and dips, so it is imperative no bone o hard connective tissue reaches the customer.

Gelatine filtration with ceramic membranes from atech ensures that neither the finest bone fragments nor hard connective tissue get into the end product.

A series of complex steps

The gelatine manufacturing process involves a series of complex steps, beginning with the washing and extracting of raw materials before the critical filtration stages due to the high level of contaminants solid matter present in the initial raw materials.

Ultrafiltration technologies with or without diafiltration remove not only salts but also the smallest impurities such as bitter substances or other taste and smell substances. In protein-water mixtures, depending on the pre-treatment, the impurities still remain, which can be separated from the desired product by using membranes.

A world leader in the development and production of gelatine and other advanced collagen proteins has been operating membrane filtration plants with atech membranes for clear filtration of gelatine for many years. Companies from all sectors, primarily from the food and pharmaceutical industries, the health & nutrition sector and the photographic industry are among his customers. Therefore, it is extremely important to supply only high-quality products

Atech multi-channel membranes with 6 mm channel diameter are characterized by their longevity and process stability even at extreme temperatures.

All raw materials and solutions are processed in such a way that as many components as possible of the raw material/product used can be utilised - fats, for example, profitably for the animal feed industry and treated water for further use in the process.
