Technical Field

The invention relates to a method for validating a homogenizer valve.

The invention proposed herein is used in the food industry, in particular in the dairy industry, or in the chemical, pharmaceutical or cosmetic industry. The invention can also be used in the field of manufacturing where homogenization is a step of the production process. For example, consider the production of carbon-based nanostructured materials such as graphene and carbon nanotubes or the cellular breakdown of yeast, algae, or microorganisms for the production of intracellular materials.

Background

Even in a variant, currently known embodiment, the homogenization device comprises a high-pressure pump and a homogenization valve which acts on the fluid product in order to:

-comminuting the particles of the fluid to make them uniform in size, to reduce the mean size and the variance of the distribution, in order to stabilize the product and increase its shelf life in the case of emulsions;

in the case of pharmaceutical applications, the destruction of the cell membrane in order to facilitate the extraction of the active ingredient;

-altering the structure of the particles in the case of chemical applications and cellulose or unicellular organisms.

For most products, the main parameters defining the level of homogenization are the average particle size and the standard deviation.

According to a known solution, the homogenization valve placed downstream of the piston pump comprises a first chamber receiving the fluid delivered from the pump at high pressure and a second chamber able to supply the exiting homogenization fluid at low pressure. Homogenization is obtained by forcing the fluid through the gap of reduced size obtained between the first and second chambers.

Both single and dual stage homogenizer configurations are known.

So far, the testing of the homogenisation device before installation includes mechanical and electrical tests.

The water is recirculated in the homogenizer valve and therefore the actual ability to reach the operating pressure of the valve design cannot be verified.
