Description

Cooling machine for ice cream Technical Field The utility model relates to the technical field of ice cream production equipment, in particular to a cooler for ice cream. Background An ice cream cooler is an indispensable device in the process of producing ice cream, and has the main function of rapidly and uniformly cooling ice cream raw materials. Conventional cooling methods include the use of ice water baths or direct freezing, but these methods have problems of uneven cooling, low efficiency, and difficulty in control. Along with the improvement of the ice cream market on the product quality and the production efficiency, modern ice cream coolers adopt more advanced designs, such as a double-layer cylinder structure (a cooling cavity is formed between an inner cylinder and an outer cylinder), and indirect cooling is performed by using a refrigerant medium so as to realize a more efficient and more uniform cooling effect. However, in practice, ice cream raw materials tend to adhere to the inner drum wall during cooling, resulting in local supercooling and even freezing, which not only affects the cooling efficiency, but may also result in reduced product quality. Therefore, how to effectively remove the ice cream materials on the cylinder wall becomes one of key points for improving the performance of the ice cream cooler. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, an object of the present utility model is to provide a cooler for ice cream, which is used for solving the problem that ice cream raw materials are easy to adhere to the inner cylinder wall surface during cooling in the prior art. To achieve the above and other related objects, the present utility model provides the following technical solutions: The cooling machine for the ice cream comprises a barrel body, wherein the barrel body comprises an inner barrel for containing ice cream raw materials, an outer barrel arranged on the periphery of the inner barrel, a cooling cavity for accommodating refrigerant media is formed between the inner barrel and the outer barrel, top plates are arranged at the tops of the inner barrel and the outer barrel, bottom plates are arranged at the bottoms of the inner barrel and the outer barrel, a feeding hole communicated with the inner barrel is formed in the top plates, a discharging hole for leading out the ice cream in the inner barrel to the outside is formed in the bottom plates, and a barrel wall scraping device is arranged in the inner barrel. According to the technical scheme, ice cream raw materials enter the inner cylinder through the feeding port on the top plate, the outer cylinder surrounds the periphery of the inner cylinder, and a cooling medium is placed in the cooling cavity between the inner cylinder and the outer cylinder. The refrigerant medium plays a role in absorbing heat of the ice cream raw material in the inner barrel through a heat exchange principle, so that the temperature of the raw material is reduced, and the ice cream raw material is gradually cooled. The cylinder wall scraping device arranged in the inner cylinder starts to work. During the cooling process of the ice cream raw materials, part of the raw materials can freeze and adhere to the wall of the inner barrel, and the barrel wall scraping device can scrape off the raw materials adhered to the barrel wall, so that the raw materials return to the inner barrel again to participate in the whole cooling and mixing process. The cooling device not only ensures the uniformity of raw material cooling in the inner cylinder and avoids the excessive cooling or freezing of the raw material at the cylinder wall, but also can improve the utilization rate of the raw material and prevent the waste of the raw material. In an embodiment of the present utility model, the cylinder wall scraping device includes an upper rotating block rotatably disposed on the top plate, a lower rotating block rotatably disposed on the bottom plate, a scraping assembly connected between the upper rotating block and the lower rotating block, and a driving assembly for driving the lower rotating block to rotate. According to the technical scheme, in the working process, the driving assembly drives the lower rotating block to rotate, and the lower rotating block transmits power to the upper rotating block through the scraping assembly, so that the lower rotating block and the upper rotating block synchronously rotate. The scraping component moves circularly on the inner cylinder wall surface along with the rotation of the upper and lower rotating blocks, scrapes down frozen materials attached to the cylinder wall, keeps the cylinder wall clean and promotes the uniform cooling of the materials. The scraped material is mixed into the inner barrel main body material again, uniform cooling is realized through the continuous effect of the refrigerant, and finally the material is discharged from the discharge port.
