INSTALLATION FOR THERMAL TREATMENT OF FROZEN DOUGH PIECES

摘要

FIELD: food industry.SUBSTANCE: installation for thermal treatment of frozen dough pieces contains a horizontally positioned cylindrical screen body where a cylindrical resonator chamber is coaxially positioned so that their generatrices interface in one line wherein a milling mechanism is embedded. There are gaps, sized less than a quarter wave length, along the side surfaces of the resonator chamber and the screen body; the gaps are positioned in a single vertical plane. The UHF generator unit is installed on the base of the screen body so that the radiator is located inside the resonator chamber where dielectric rolls rotating by means of the motor reducer are positioned along the gap 12. There are screen overlaps for power flow radiation restriction between the gaps.EFFECT: invention allows to intensify the dough pieces defrosting process.1 dwg
