Especially suited for the freezing of juices and similar products, it has a cooling tank (2) that supplies the product by means of an impelling pump (4) to a freezing chamber (5) to which a liquefied gas at a temperature of around -140ºC, preferably nitrogen, in addition to pressurised air through an electro-valve (12) are also supplied, producing both the transformation of the juice into micro-drops or pellets and the instant freezing thereof inside the freezing chamber (5), which exit the chamber through one or more dispensing valves (14), said freezing not entailing a reduction in the original characteristics of the juice, in terms of its vitamin, protein and enzyme content.
