CRYOGENIC COAGULATOR Russian patent published in 1997 - IPC

FIELD: agriculture. SUBSTANCE: cryogenic coagulator has hollow housing formed as cylinder having upper base formed as funnel oriented with its neck portion into housing cavity and lower hemispherical base oriented with its convex part into cylinder cavity. Lower base is provided with plates connected with it and oriented inside the cylinder perpendicular to its axis. Housing is made double-walled to reduce heat loss and wall space is vacuumized. Plates on lower base allow optimum base temperature to be maintained by intensified heat-exchange process between base, refrigerant and animal skin surface. EFFECT: increased efficiency, simplified construction, reduced process time. 2 cl, 2 dwg
