Description

Technical Field

[0001] The utility model relates to the technical field of ice cream machines, in particular to an ice cream puffing device. Background Art

[0002] Ice cream is a frozen product that is deeply loved by people. It is made of drinking water, milk, milk powder, cream, sugar and other raw materials, with appropriate amount of food additives added. It is made into a frozen food through mixing, sterilization, homogenization, aging, freezing and hardening processes. When making ice cream, usually the ice cream ingredients are added into the barrel first, then the lid is closed and the ice cream machine is started. It is easy to operate. In addition to the flavor of the ice cream itself, another important factor that makes ice cream popular among people is the condensation puffing of the ice cream. If the puffing effect of the ice cream produced is good, the taste of the ice cream will be greatly improved.

[0003] The condensation and puffing of existing ice cream is mainly achieved by pumping air into a mixing cylinder. While the raw materials are condensed in the mixing cylinder, they are mixed with the pumped air, thereby achieving the effect of condensation and puffing. However, due to the puffing structure of pumping air into the mixing cylinder, the raw materials and the air are not mixed evenly in the mixing cylinder, so that the puffing effect of the produced ice cream is poor and the taste is not good. In addition, when the liquefaction degree of the ice cream raw materials is low, it is easy to flow back from the air outlet to the air inlet pipe. Therefore, an ice cream puffing device is proposed.

[0028] Please refer to Figure 1-Figure 4 The utility model provides a technical solution: an ice cream puffing device, including a stirring cylinder 1 and an oxygen pump 13, the top inner surface of the stirring cylinder 1 is rotatably connected with a stirring shaft 2, the top outer surface of the stirring cylinder 1 is fixedly installed with a motor 15, the output end of the motor 15 is fixedly connected with the stirring shaft 2, the outer surface of the stirring shaft 2 is fixedly connected with a plurality of stirring rods 3, the stirring shaft 2 and the stirring rods 3 are both hollow, the interior of the stirring shaft 2 is fixedly connected with an air inlet pipe 4, the interior of the stirring rod 3 is fixedly connected with a transverse pipe 5, the transverse pipe 5 is connected with the air inlet pipe 4, the air inlet pipe 4 rotates and penetrates the bottom outer surface of the stirring cylinder 1, and the oxygen pump 13 is installed on the top outer surface of the stirring cylinder 1, and the oxygen pump 13 is installed on the top outer surface of the stirring cylinder 1, and the output end of the motor 15 is fixedly connected with the stirring shaft 2, and the outer surface of the stirring shaft 2 is fixedly connected with a plurality of stirring rods 3, and the stirring shaft 2 and the stirring rods 3 are both hollow, the interior of the stirring shaft 2 is fixedly connected with an air inlet pipe 4, the interior of the stirring rod 3 is fixedly connected with a transverse pipe 5, the transverse pipe 5 is connected with the air inlet pipe 4, the air inlet pipe 4 rotates and penetrates the bottom outer surface of the stirring cylinder 1, and the oxygen pump 13 is installed on the top ... The output end of the pump 13 is fixedly connected to a delivery pipe 14, and the other end of the delivery pipe 14 away from the oxygen pump 13 is fixedly connected to the air inlet pipe 4. The top outer surface of the cross pipe 5 is fixedly connected to the air outlet pipe 6, and the top outer surface of the air outlet pipe 6 is fixedly connected to a connecting pipe 7, and the top outer surface of the connecting pipe 7 is provided with an air outlet hole 12, and the bottom outer surface of the connecting pipe 7 is provided with a through hole 11, which is connected to the air outlet pipe 6. The top inner surface of the connecting pipe 7 is fixedly connected to two first elastic members 8, and the bottom outer surfaces of the two first elastic members 8 are fixedly connected to a cross plate 9, and the bottom outer surface of the cross plate 9 is fixedly connected to a blocking block 10.

[0029] The ice cream raw materials are transported into the mixing cylinder 1, and the ice cream machine is turned on. The motor 15 drives the stirring shaft 2 to rotate, driving the stirring rod 3 to stir the ice cream raw materials. When the oxygen pump 13 works, oxygen is transported to the intake pipe 4 through the delivery pipe 14. The oxygen enters the horizontal pipe 5 through the intake pipe 4. As the amount of oxygen increases, the air pressure increases. Under the action of the air pressure, Figure 4As shown, the blocking block 10 is pushed to move upward, the first elastic member 8 is compressed, and then the through hole 11 is connected, and oxygen enters the connecting pipe 7 through the through hole 11, and is discharged through the air outlet 12 and sprayed toward the ice cream raw materials. As the ice cream is stirred, the oxygen is fully mixed with the ice cream raw materials to improve the puffing effect, and the hardness of the ice cream is controlled by controlling the amount of gas delivered by the oxygen pump 13, thereby improving the taste of the ice cream. After the oxygen pump 13 stops delivering oxygen, the first elastic member 8 drives the cross plate 9 to make the blocking block 10 block the through hole 11 to prevent the ice cream from flowing back into the air outlet pipe 6.

[0030] In some embodiments, Figure 5 As shown, the top outer surface of the mixing tank 1 is fixedly connected to a pressure relief cylinder 16, the top inner surface of the pressure relief cylinder 16 is fixedly connected to a second elastic member 17, the bottom outer surface of the second elastic member 17 is fixedly connected to a piston 18, the piston 18 is movably connected to the inside of the pressure relief cylinder 16, and a pressure relief hole 19 is opened on the outer surface of the pressure relief cylinder 16, and the pressure relief hole 19 is located above the piston 18.

[0031] When oxygen is transported into the mixing tank 1, the air pressure will increase. When the air pressure in the mixing tank 1 reaches a certain level, the air pressure squeezes the piston 18, causing the second elastic member 17 to be compressed. When the piston 18 moves to above the pressure relief hole 19, the gas is discharged to balance the pressure.

[0032] In some embodiments, a sealing ring is provided on the outer surface of the bottom of the rotation point between the air inlet pipe 4 and the stirring cylinder 1 .

[0033] In this embodiment, the sealing performance of the rotation point between the air inlet pipe 4 and the stirring rod 3 is increased by a sealing ring.

[0034] like Figure 4 As shown, in some embodiments, the blocking block 10 is in the shape of a truncated cone with a larger top and a smaller bottom, and a sealing gasket is fixedly connected to the outer surface of the blocking block 10 .

[0035] The truncated cone-shaped blocking block 10 with a larger top and a smaller bottom facilitates the blocking block 10 to block the through hole 11 , and the sealing gasket increases the sealing performance between the blocking block 10 and the through hole 11 .

[0036] In some embodiments, Figure 4 As shown, the inner surface of the connecting pipe 7 is fixedly connected to two vertical rods, the horizontal plate 9 is movably sleeved on the outer surfaces of the two vertical rods, and the two first elastic members 8 are respectively sleeved on the outer surfaces of the two vertical rods.

[0037] like Figure 4 As shown, in some embodiments, the horizontal plate 9 is limited by two vertical rods to prevent the block 10 from being unable to accurately correspond to the through hole 11 when the first elastic member 8 is reset.

[0038] In some embodiments, the air intake pipe 4 and the cross pipe 5 are both hard pipes, and a rotary joint is provided at the connection between the air intake pipe 4 and the delivery pipe 14 .

[0039] The rotary joint and the hard air inlet pipe 4 are used to prevent the delivery pipe 14 and the air inlet pipe 4 from being entangled during rotation, thereby causing the delivery pipe 14 to be blocked.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
