CMC-ATEX System for the production of hydroalcoholic gel

Hydrocolloid compounds are usually available in dry powder form, which must be diluted in water to obtain the desired colloidal solution.
When these powders come into contact with water, lumps quickly form and it is difficult to obtain a homogeneous mixture using a conventional agitator. To overcome this problem, this mixing unit incorporates a rotor-stator mixer at the bottom of the tank that shears the product, thereby increasing the water-additive contact area.
A cowles-type agitator fitted in the tank allows efficient circulation of the powder to the mixer lower head and also helps improve the dispersion time.
A product can become very viscous when the process requires using high concentrations of gelling agents, so using an additional anchor type agitator to ensure a completely mixed product may be necessary.
With its standard configuration, this equipment is set up to work with products up to 5000 cP. The configuration can be adapted accordingly for use with more viscous products.
