Abstract
The invention relates to a method for obtaining a product in the form of deep-frozen granules, particles of beads having a high dissolved-gas content from a liquid, semi-liquid or paste-like matrix, that comprises two subsequent steps: a matrix gasification step that comprises the incorporation of gas at a pressure higher than 2 bars; and a quick deep-freezing step using a cryogenic fluid.
Claims5
A method for obtaining a deep-frozen product starting from a liquid matrix, the method comprising:
- a gasification step of the liquid matrix by incorporating gas under a pressure between 2 bar and 10 bar in order to dissolve gas in the liquid matrix, wherein said gas is one of nitrogen, nitrous oxide, and a noble gas;
- a deep-freezing step of the liquid matrix after the gasification step with liquid nitrogen, the deep-freezing step occurring at a pressure between 2 bar and 10 bar;
- and
- obtaining the deep-frozen product in a form of deep-frozen granules, particles or beads, which are dense contain dissolved gas and have a size of 1 mm-2 cm.
A method for obtaining a deep-frozen product starting from a matrix having a liquid, semi-liquid or a pasty viscosity, the method comprising:
- a gasification step of the matrix having the liquid, semi-liquid or pasty viscosity by incorporating gas under a pressure between 2 bar and 10 bar in order to dissolve gas in the matrix, wherein said gas is one of nitrogen, nitrous oxide, and a noble gas;
- a deep-freezing step of the matrix after the gasification step with liquid nitrogen, the deep-freezing step occurring at a pressure between 2 bar and 10 bar;
- and
- obtaining the deep-frozen product in a form of deep-frozen granules, particles or beads, which are dense contain dissolved gas.
