CONVECTIVE AND VACUUM DRYER Russian patent published in 2015 - IPC F26B17/10 F26B5/04 

FIELD: heating, drying.

SUBSTANCE: invention relates to drying equipment, namely to drying devices with active hydrodynamic modes intended for drying of disperse materials in the suspended curled layer, and can be applicable in processing of agricultural products, producing of medical preparations, etc. The convective and vacuum dryer contains valves in the heat carrier supply pipelines, and the upper and lower parts of the cone cylindrical chamber contain hatches with electromagnet, and the cone cylindrical chamber has vacuum, temperature and humidity sensors, and pipelines with valves for connection of the vacuum pump are laid to the heat carrier pipelines. Valves in the heat carrier pipeline and in the discharge pipeline for connection of the vacuum pump, electromagnets in hatches, and also vacuum, temperature and humidity sensors are connected to the electronic control system.

EFFECT: invention shall provide decrease of costs of energy for drying, and also shortening time for the drying process.
