Gas-liquid synchronous mixing and puffing device and ice cream machine comprising same

Abstract

The invention discloses a gas-liquid synchronous mixing and puffing device and an ice cream machine comprising the same. The device comprises a piston cylinder A, a piston cylinder B, an air inlet channel, a feeding pipe, a discharging pipe and a driving device, under the action of the driving device; the piston cylinder A can pump outside air into a cylinder block A; meanwhile, the piston cylinder B can pump the slurry in a raw material cylinder into a cylinder block B; under the continuous action of the driving device, the piston cylinder A can inject air in the cylinder block A into the discharging pipe, meanwhile, the piston cylinder B can inject the slurry in the cylinder block B into the discharging pipe; air and slurry are synchronously injected into the discharging pipe; under thethrust action of a piston rod A and a piston rod B; air and the slurry can be fully mixed in the discharging pipe, so that the ice cream and the milkshake achieve a relatively good puffing effect, thewhole puffing device is basically not influenced by the viscosity and the particles of the slurry and is not easily blocked by the particles in the slurry, and the puffing rate of the ice cream and the milkshake can be relatively accurately controlled.

Description

technical field [0001] The invention relates to a gas-liquid synchronous mixing and puffing device and an ice cream machine comprising the same. Background technique [0002] When making ice cream and milkshake, the puffing rate has a very important influence on the quality and taste of ice cream and milkshake. The milkshake becomes a loose product with a good appearance and a smooth and smooth taste. [0003] In order to achieve the ideal effect of puffing ice cream and milkshakes, the existing ice cream machines and milkshake making machines basically install an puffing device at the position where the bottom of the raw material tank is connected to the feed pipe. Feed hole, the slurry enters the feed pipe through the feed hole, and then flows into the refrigeration cylinder. There is a vent hole on the upper end of the puffing device. When the slurry flows into the refrigeration cylinder, the air enters the refrigeration cylinder from the vent hole on the upper end of th...

[0003] In order to achieve the ideal effect of puffing ice cream and milkshakes, the existing ice cream machines and milkshake making machines basically install an puffing device at the position where the bottom of the raw material tank is connected to the feed pipe. Feed hole, the slurry enters the feed pipe through the feed hole, and then flows into the refrigeration cylinder. There is a vent hole on the upper end of the puffing device. When the slurry flows into the refrigeration cylinder, the air enters the refrigeration cylinder from the vent hole on the upper end of the puffing device. , the slurry is stirred and mixed with air, and frozen to make ice cream and milkshake with a certain expansion rate, but this kind of expansion device is greatly affected by the viscosity of the slurry and particles, and it is easy to be blocked by the particles in the slurry. The puffing rate of ice cream and milkshake is difficult to be accurately controlled, and in the refrigeration cylinder, the air and slurry liquid are mixed and stirred in a free-flowing state. The mixing effect of air and slurry liquid is poor, and ice cream and milkshake cannot Achieve better puffing effect, uneven puffing, low puffing rate, poor taste of ice cream and milkshake, not soft and smooth enough
