Abstract
A heat exchange apparatus for use in the production of sugar confectionery or for tempering chocolate including a vessel with a tubular heat transfer surface. The vessel defines an inlet and outlet higher than the inlet. Heat exchangers, such as steam jackets and modulating valves are provided for supplying heat to or removing heat from the heat transfer surface. A shaft is located longitudinally along the length of the vessel and is provided with at least one piston. The shaft is reciprocated in the vessel so that the product is agitated and substantially the entire heat transfer surface of the vessel is swept by the piston during each reciprocation cycle.
Claims15
A heat apparatus for use in the production of a confectionery or chocolate product comprising a vessel with a tubular heat transfer surface, said vessel defining an inlet and an outlet, heat exchange means for supplying heat to or removing heat from the heat transfer surface, a shaft located longitudinally along a length of the vessel and provided with at least one piston, and means for reciprocating said shaft within the vessel whereby substantially entirely said heat transfer surface of the vessel is swept by the piston during at least each reciprocation cycle, and wherein the heat exchange means are supplied with a heat transfer fluid from a modulating valve, and in that, at least one sensor is interactive with said vessel so as to deduce a temperature within the vessel, and control means are provided for controlling operation of the modulating valve to increase or to restrict a rate at which the heat transfer fluid is supplied to the heat exchange means dependent on said temperature.
An evaporation apparatus for use in the manufacture of sugar confectionery comprising a vessel with a tubular heat transfer surface and defining an inlet and an outlet positioned higher than the inlet, and heat supply means for supplying heat to the heat transfer surface, a shaft located longitudinally along a length of the vessel and provided with a plurality of spaced pistons, and means for reciprocating said shaft within the vessel whereby substantially entirely said heat transfer surface of the vessel is swept by the pistons during at least each reciprocation cycle, and wherein the heat supply means are supplied with a heat transfer fluid from a modulating valve, and in that at least one sensor is provided for deducing a temperature within the vessel, and control means are provided for controlling operation of the modulating valve to increase or to restrict a rate at which the heat transfer fluid is supplied to the heat supply means dependent on said temperature.
A chocolate tempering apparatus comprising a vessel with a tubular heat transfer surface and defining an inlet and an outlet positioned higher than the inlet, and heat exchange means for transferring heat to or from the heat transfer surface, a shaft located longitudinally along a length of the vessel and provided with a plurality of spaced pistons, and means for reciprocating said shaft within the vessel whereby substantially entirely said heat transfer surface of the vessel is swept by the pistons during at least each reciprocation cycle, and wherein the heat exchange means are supplied with a heat transfer fluid from a modulating valve, and in that at least one sensor is is adapted to deduce a temperature within the vessel and control means are provided for controlling operation of the modulating valve to increase or to restrict the rate at which the heat transfer fluid is supplied to the heat exchange means dependent on said temperature.
