Abstract
The heat exchanger is provided with a plurality of recirculating needles each having an outer tube having one end thereof terminated in a closed needle point and an inner tube disposed within the outer tube having one end thereof spaced from the needle point and providing a predetermined clearance along its length between the outer wall of the inner tube and the inner wall of the outer tube. The clearance of each needle is in communication with a pressurized heat transferring medium supply manifold and the inner tube is in communication with a discharge and return manifold. The clearance and inner tube of each needle provides a needle that circulates the pressurized heat transferring medium therethrough. The pressurized heat transferring medium may be hot to heat the meat into which the needles are inserted, or the pressurized heat transferring medium may be cold to chill the meat into which the needles are inserted.
