  • Publication number: 20150330682
    Abstract: A direct expansion evaporator includes a feeding channel having a feeding end and a dispensing end for raw material feeding therethrough, and a heat exchange channel thermally communicating with the feeding channel for guiding refrigerant passing through the heat exchange channel to heat-exchange with the raw material to form a frozen product. The heat exchange channel has a pre-cooling portion and a freezing portion, wherein the heat exchange channel is configured to ensure a traveling time of the refrigerant at the pre-cooling portion to be longer than a traveling time of the refrigerant at the freezing portion. The raw material is guided to flow from the pre-cooling portion to the freezing portion so as to initially pre-cool the raw material and to substantially freeze the raw material to form the frozen product before the frozen product is dispensed at the dispensing end of the feeding channel.

  • Patent number: 9127869
    Abstract: A direct expansion evaporator includes an inner guiding duct defining a feeding channel for guiding raw material, and an outer guiding duct enclosing the inner guiding duct therewithin to form a heat exchange channel between the outer and inner guiding ducts for guiding refrigerant flowing along the heat exchange channel to heat-exchange with the raw material along the feeding channel, wherein a helix indention is formed at the outer guiding duct to form the heat exchange channel partitioned by a helix partition, wherein a peak of the helix partition is biased against an outer surrounding wall of the inner guiding duct to conceal the heat exchange channel along the inner guiding duct in a weld-less manner.
