ABSTRACT:
The invention is concerned with the ultra-high temperature treatment of liquids, such as milk, with a minimum of thermal damage. The present invention provides a method and apparatus for indirect ultra-high temperature treatment of a liquid in which the flow rate of a liquid through a holding tube (20) is capable of being varied and in which the holding temperature of the liquid is selected between the characteristic holding temperature for that liquid and a temperature above the said characteristic holding temperature by a temperature control means (28).
The invention provides a method and apparatus for ultra-high temperature treatment which reduces the thermal damage to a product when variable plant throughputs are employed.
