  • Method and apparatus for heating liquid samples, and a container for use in the apparatus
    Patent number: 5260019
    Abstract: In a method and an apparatus for heating large amounts of uniform milk samples (11) to about 40.degree. C. preparatory to laboratory analyses, the samples are currently introduced into a carrousel-like machine. The machine has two axially offset levels (II and III), one (III) of which being a transport level and the other (II) a heating chamber (7) in which the samples are heated by high frequency energy, preferably in the form of microwaves. The samples are introduced mechanically into the heating chamber and maintained there during heating with current measurement of their temperature. When the temperature measurement shows that the samples have reached a desired temperature, they are released and fall back to the transport level and are transported out of the machine.
