Batch vacuum mixer for emulsion-based products

The production of creams or ointments can be either be a water in oil (w/o) or oil in water (o/w). When added to water, thickening, stabilizing and emulsifying ingredients can form agglomerates, in the same way that lumps can be formed in the oil phase. You thus need a solution capable of hydrating and dispersing the ingredients so well that the emulsion does not break during oil addition.

Modular designed mixing and dispersing solution

Designed by AZO LIQUIDS, the Batch vacuum processing plants type zoatec® BG can be used for mixing, dispersing, and emulsifying two different liquids, or liquids and dry powders.

Since it’s designed with standardized modules, the model can be adapted to different requirements with exceptional flexibility. This ensures shorter startup and installation times. AZO’s homogenizer has an innovative and unique configuration, making the homogenizer fully reachable from the outside. Thus, the entire working area can be removed without dismantling a lot of pipelines, making the cleaning and maintenance of the equipment very easy.

Moreover, the unit can be adapted to meet the current guidelines and standards for quality assurance, including Good Manufacturing Practice, SIP, and ATEX.

Apart from the pharmaceutical and cosmetics industry, for the production of ointments, gels and creams it can also be used for a wide range of liquid to paste-like applications in the food industry. These include sauces, ketchup, fish paste, marmalade and jam, chocolate fillings, concentrated soup, mayonnaise, dressings, cheese spread, and juices.
