MICROWAVE RADIATION DETECTOR AND HEAT TREATMENT DEVICE HAVING SAME Russian patent published in 2014 - IPC G01K11/00 G01J5/00 G01N22/00 G01N33/02 

FIELD: physics.

SUBSTANCE: disclosed is a heat treatment device designed for heat treatment of protein-containing food products (3) and having a microwave radiation detector (1) for measuring internal temperature of the protein-containing food product (3), movement means for moving the products (3) through the device in a movement direction (y-direction) such that the products (3) pass under a fixed detector (1), and heat treatment means controlled by a signal from the detector (1). The detector (1) has a sensitive surface of 0.1-180 mm², which detects microwave radiation emitted by the product and which faces the movement means. The detector is capable of measuring internal temperature of the product at a measurement wavelength which is shorter than length of the product in the horizontal direction (x-direction), perpendicular to the movement direction (y-direction).

EFFECT: high accuracy of obtained data.
