FIELD: food industry.
SUBSTANCE: invention relates to food industry, in particular, to devices for thermal treatment of loose food product with usage of a heat medium represented mainly by air. The installation has a closed main air circuit with an air chamber, a cyclone, the main circuit air supercharger, heater with a filtering element that are all interconnected by means of a closed air duct system 6. The installation contains a charging vessel connected to the working chamber by means of the charging damper. A grid is installed at the working chamber inlet so that to enable organisation of circulation and whirling movement of the product being treated in such grids to ensure intensive and uniform roasting of the product. The cooler interacts with the working chamber and is connec6ted to it by means of the discharging damper. The cooler has a discharging damper of its own. The cooler air supercharger connects (via its outlet nipple) the cooler exhaust air flow to the air flow from the main circuit air supercharger. The working chamber is equipped with a transition nipple.
EFFECT: invention implementation allows to enhance the ready product quality.
