20120137719 | Direct expansion evaporator - 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. | 06-07-2012 |
20120219442 | Pump device for ice cream or yogurt machine - A pump device for a frozen product machine includes a pump casing, first and second rotor gear, and a sealing arrangement. The first and second rotor gears fit in a pumping cavity of the pump casing in a rotatably movable manner that creates a suction effect for pumping and mixing liquid mixture with air to produce a mixture product. The sealing arrangement includes a plurality of sealing elements provided between two outer side surfaces of the first and second rotor gears and inner side surfaces of the pump casing for ensuring the liquid mixture and air being sealed and mixed within the pumping cavity through the first and second rotor gears and for preventing the first and second rotor gears from being direct-surface contact of the pump casing. | 08-30-2012 |
20130145793 | Direct Expansion Evaporator - 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. | 06-13-2013 |
20130157556 | Air Inlet Arrangement for Ice Cream or Yogurt Machine - An air inlet arrangement for an ice cream machine or yogurt machine includes an air-solution tube supported in a solution container which is adapted for storing a predetermined volume of solution at a predetermined fluid elevation, and an air nozzle. The air-solution tube has an elongated structure defining a top end, a bottom end, and a process channel between the top end and the bottom end, wherein the air-solution tube has a height greater than the fluid elevation of the solution container, wherein a volume of the air-solution tube is such that the air-solution tube is arranged to contain 80 g or less of the solution. | 06-20-2013 |
20130279288 | Frosty swirl machine - A frosty swirl machine includes a housing, a funnel, an auger for swirling ice-cream with other additives to become a mixture, a driving unit, and a protective cap. The protective cap has a passage opening movably mounted at a mixture outlet of the funnel, in such a manner that the protective cap is capable of moving between a opened position and a closed position, wherein in the opened position, the protective cap is moved to align the passage opening with the mixture outlet of the funnel so as to allow the mixture to pour out of the funnel through the mixture outlet and the passage opening, wherein in the closed position, the protective cap is moved to block the mixture outlet so as to prevent the mixture from being poured out of the funnel. | 10-24-2013 |
20140348669 | Pump Device for Ice Cream or Yogurt Machine - A system includes a pump device for producing a mixture product, a casing having a concealed cavity for receiving the mixture product via the pump device; and a clutch unit operatively linked to the pump device for controllably maintaining an interior pressure of the concealed cavity at a predetermined threshold. Accordingly, the pump device is activated by the clutch unit for delivering the mixture product into the concealed cavity through an inlet of the casing until the interior pressure of the concealed cavity reaches the predetermined threshold and is deactivated by the clutch unit for stop delivering the mixture product into the concealed cavity when the interior pressure of the concealed cavity reaches the predetermined threshold. | 11-27-2014 |
20150330682 | Direct Expansion Evaporator - 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. | 11-19-2015 |
20160029661 | Frosty Swirl Machine - A frosty swirl machine includes a housing, a funnel, an auger for swirling ice-cream with other additives to become a mixture, and a protective cap. The protective cap has a passage opening movably mounted at a mixture outlet of the funnel, in such a manner that the protective cap is capable of moving between a opened position and a closed position, wherein in the opened position, the protective cap is moved to align the passage opening with the mixture outlet of the funnel so as to allow the mixture to pour out of the funnel through the mixture outlet and the passage opening, wherein in the closed position, the protective cap is moved to block the mixture outlet so as to prevent the mixture from being poured out of the funnel. | 02-04-2016 |
