HYGIENIC COOLING CHANNEL Russian patent published in 2016 - IPC A23G7/00 F25D13/06 

FIELD: heating.

SUBSTANCE: cooling channel to cool the cooled products contains cooling tower with inlet and outlet ends, driven conveyor with installed cooled product, which is transported through the cooling tower, casing enclosing the conveyor and creating cooling zone in the conveyor area, filtering unit for air filtering, cooling unit to cool cooling zone, and at least one fan in thermodynamical interaction with cooling unit. The cooling unit and fan are installed in casing section made separately from the cooling zone, and sealed from it. Between the fan and cooling zone for the cooled air supply only communication by fluid is provided. The filtering unit is installed before the cooling unit relatively to the air flow. Cooling unit contains heat exchanger being in thermodynamical interaction with environment, it is installed in heat exchange chamber. Filtering chamber is separated from cooling zone and is sealed from it, it is connected by fluid with the cooling unit via the filtering chamber. Heat exchange, filtering and ventilation chambers project beyond the conveyor to both its sides.

EFFECT: use of this group of inventions ensures long-term cooling of the product without microorganisms origin.
