TOROIDAL APPARATUS FOR PRODUCTION OF FRUIT AND VEGETABLE CHIPS Russian patent published in 2013 - IPC A23L1/00 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. The toroidal apparatus for production of fruit and vegetable chips includes a toroid-shaped sectional body positioned on a slanted surface, sectional working chambers installed in guides so that to enable movement on spherical wheel supports and equipped with buffers attached to the axles, loading and discharge bins, a steam conduit, moisturisers and a drive; the novelty consists in the fact that serially interconnected sections are positioned inside the toroid-shaped sectional body, such as: the raw material pre-heating section, a convective drying section, a preliminary hydrothermal treatment (PHTT) section (positioned between the UHF drying sections) and the dry product cooling section; the convective drying section is equipped with a recirculation circuit for the heat medium supply; the PHTT section is equipped with moisturisers, a heat exchanger and a circulation pipeline with a pump; the UHF drying sections are connected, via the steam conduit, to the PHTT section for the liquid pre-heating and are equipped with UHF units having magnetrons (positioned inside the section in a successively alternating way), waveguides and antenna radiators; before the first UHF drying section a trap is installed; the dried product cooling section is separated from the UHF drying section by a protective region having a rectangular cross-section; the guides before the discharge bin are arranged along a helical line so that to enable the sectional working chambers turnover relative to the torus ring cross-section axle without return to the initial position.

EFFECT: proposed is a toroidal apparatus for production of fruit and vegetable chips.
