The design of the plant consists of a main operating vessel, jacketed for heating and cooling and thermal insulation, and equipped with an agitator with scrapers for a special macro-mixing of the product. Scrapers effectively remove the product from the container sides for maximum heat and cold dynamics in the thin film. The special geometry of the working tank insures lack of unmixed zones.

Capacity, depending on the application, ranges from 15 to 80 % of total volume of the vessel.

The main working element – the rotor-stator homogenizer – is installed in the bottom of the conical working vessel and provides emulsification and forced circulation of the product. The homogenizer has one main input, from the cone of the working vessel, and three auxiliary inputs, which are connected to the funnel or complementary tanks to add additional ingredients to the product.

When adding powdered ingredients directly into the strong vacuum created in the area of highest shear rate, the powder is immediately dispersed and wetted – thereby achieving complete wetting, de-agglomeration and the uniform distribution of solid particles in the liquid.

THE BASIC FEATURES OF THE VACUUM HOMOGENIZING PLANT INCLUDE:
a working tank, two tanks for additional ingredients, a homogenizing unit, a vacuum pump, lid lift, and automatic control system based on an industrial controller. Standard lid equipment includes an agitator drive, inlets fitted for vacuum connection and cleaning solutions, gauge, manhole and an inspecting glass.

If the manufacturer requires a product with unbroken solid components then the product is unloaded with the bottom pump, without using the homogenizer. Plant design complies with FDA GMP, and is convenient for inspection and cleaning; also, there are no «dead zones» while cooking and mixing.
