Process and apparatus for investigating and controlling changes of state

A process and apparatus for measuring rheological properties of semi-solid bodies. The apparatus comprises a vessel (4) containing the body (5 ) to be tested, a measuring head (3) immersed in the vessel (4) in the middle of the body, and a drive for driving the head (3) in rotation through the intermediacy of an axle. The driver imparts a sinusoidal or pseudo-sinusoidal rotational motion to the axle (2), a torque sensor (7) and an angle sensor (8) which are mounted on the axle (2) and are both connected to a processing device for processing information, such as a device for processing signals (9) connected to a microcomputer (10).

Process and apparatus for measuring rheological properties of semi-solid

A process of sterilization or decontamination of apparatus, characterized in that an aqueous solution containing at least 0.01% of a compound of the formula ##STR1## in which R represents a C.sub.5 -C.sub.14 n-alkyl radical in the form of the base or a salt thereof, is applied to the apparatus at a temperature in the range of 30.degree. to 120.degree. C. at atmospheric pressure. The process is suitable in particular for the sterilization of milk processing circulation equipment.
