Description
Technical Field
The invention relates to the technical field of ice cream machines, in particular to a novel feeding puffing device and an ice cream machine with the same.
Background
The traditional ice cream machine has the following expansion modes:
1. the method has the advantages that the air adding device is not used, liquid ice cream materials freely enter the freezing cylinder from the material basin for refrigeration, the amount of air expanded by the liquid ice cream in the freezing cylinder is the amount of air in the liquid ice cream materials, and although the method does not increase components and cost, the air content of the ice cream is low, so that the expansion rate of the ice cream is low;
2. the device is provided with the puffing rod and the vent hole at the top of the puffing rod, liquid raw materials and air freely enter the freezing cylinder by utilizing the chimney principle, although the flow of feeding can be controlled by the feeding hole smaller than the feeding hole of the material basin, and simultaneously, a part of air freely enters, pressure cannot be formed in the freezing cylinder due to the fact that air is freely fed, and the puffing rate of the ice cream is improved slightly;
3. air is injected into the freezing cylinder by an air pump, liquid ice cream material enters the freezing cylinder from a powder basin discharging hole, and the air is directly mixed with the liquid ice cream material in the freezing cylinder, so that the method has the advantages that the puffing effect can be improved to a certain extent, the cost is low, and the defect that the air in the freezing cylinder escapes from the material basin due to the communication between the freezing cylinder and the material basin feeding/discharging hole, and the large pressure is difficult to achieve in the freezing cylinder, so that the puffing effect is difficult to further improve; meanwhile, after the ice cream in the freezing tank is aerated, mixed, puffed and formed, the volume of the ice cream in the freezing tank is relatively increased, the freezing tank is communicated with a feed port of the material basin, and when the air inlet control is not good, the formed solid ice cream with the expanded volume can return to the feed port of the material basin and reversely flow out; therefore, when the ice cream machine needs to feed materials from the feeding hole of the material basin while discharging materials, the liquid ice cream materials can be prevented from entering, so that the freezing cylinder or the discharging is difficult; in addition, after the ice cream material in the freezing cylinder reaches a certain pressure or when the air pump is stopped, the ice cream material returns to the air inlet pipe of the air in a reverse direction, so that the air inlet pipe is blocked, and the subsequent air inlet is influenced;
4. air is injected into the blanking hole of the material basin by an air pump, liquid ice cream enters the freezing cylinder from the blanking hole of the material basin, and the air of the air pump enters the freezing cylinder from the feeding hole and the raw material together, so that the air of the air pump is discharged from the feeding hole while entering the freezing cylinder, and the inside of the freezing cylinder is difficult to reach higher pressure, so that the puffing effect is difficult to further improve; meanwhile, as the feeding and the air inlet share the blanking hole of the material basin, the feeding of the liquid ice cream material is easily prevented when the air is fed, thereby causing the freezing cylinder;
5. after the material is pumped from the material basin by a mechanical pump and air is mixed, the mixture is extruded into the freezing cylinder by the discharging hole. Be equipped with special gear or piston structure and take out the material pump and take out liquid ice cream material to mix with the air that gets into in the pump body, blast pipe and the basin unloading hole through the pump body form sealed passageway, make blast pipe, the basin unloading hole of the pump body to the inside airtight space of a body that forms of freezing jar, constantly pressurize through the pump body can form higher pressure, its advantage lies in: the mixed high-pressure mixed liquid can be injected into the freezing cylinder, the expansion rate is high, and the feeding is stable and the discharge amount is large; the disadvantages are that: the pump body has high sealing requirement, complex structure and high processing precision, and a special high-power motor (usually matched with a speed reducing mechanism) is required to drive the pump body to operate, the scheme has high cost, the mechanism is inconvenient to mount, clean and maintain, and the equipment cost of the ice cream machine is greatly increased; meanwhile, as the driving mechanism and the pump body need to be lubricated and sealed, the failure of the components thereof can cause food contamination of the ice cream material, causing serious food safety problems.
6.
