FIELD: food industry.
SUBSTANCE: invention relates to sugar industry. Plant for production and drying of lump sugar includes: press for moulding sweet mass to produce lump sugar, heating device for heating and drying of lump sugar, conditioning device for cooling and drying of lump sugar and transportation means for transporting lump sugar from press to heating device and, therefrom, to conditioning integrated device. Heating device includes several heaters, each of which has microwave emitter which emits microwave radiation, and waveguide guide microwave radiation from microwave radiator into drying chamber, in which heating lump sugar. At that, every heater comprises valve located at waveguide which reverse radiation cannot pass in waveguide for said valve, which makes plant more flexible in use in comparison with other.
EFFECT: invention ensures increased service life of microwave radiator.
