Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical ice making, in particular to a medical physiological saline ice smoothie making device. Background Art
[0002] In the medical field, saline is a standard medical product because its osmotic pressure is roughly the same as that of normal human plasma and tissue fluid. Therefore, it is widely used in wound treatment, intravenous injection and other scenarios. During medical surgery, low temperatures are often required to protect limbs or organs from low temperatures. For example, in limb or organ transplantation surgery, tiny ice bodies made of saline are often used to wrap and refrigerate the transplanted limbs or organs. In cardiac surgery, small ice bodies made of saline are often needed for myocardial protection and re-beating. Small ice bodies of saline are mainly used for myocardial protection. By providing a low-temperature environment for the heart during surgery, the heart's metabolic rate is slowed down, and myocardial oxygen consumption is reduced, thereby protecting myocardial cells from damage. As a myocardial protection measure, saline ice has important medical value in cardiac surgery. It helps reduce surgical risks, improve surgical success rates, and also helps patients recover after surgery.
[0003] In most hospitals, because the freezing point of physiological saline is lower than that of pure water and has a higher requirement for a sterile environment, there is no special equipment for making sterile small ice bodies. In traditional medical processes, large pieces of physiological saline ice need to be cut into small pieces manually. In this cutting process, not only is manpower wasted, but the sterile environment is difficult to maintain completely, and the cut ice is easily contaminated. In addition, the cut ice is large and usually has sharp edges. The ice even needs to be like a blade. Therefore, in the process of wrapping limbs or organs, it is not only difficult to wrap, but also easy to scratch the limbs or organs during wrapping. Summary of the invention

[0019] (III) Beneficial effects: Compared with the prior art, the present invention provides a medical saline ice smoothie manufacturing device, which has the following beneficial effects: 1. The medical saline ice smoothie making equipment uses an independent ice making device with a detachable ice making cylinder, which can ensure a sterile environment for making ice smoothies; through the rotation of the ice making cylinder, the saline inside the ice making cylinder is always in motion, which ensures the heat exchange between the saline inside the ice making cylinder and maintains a uniform heat distribution in the cylinder, so that local overcooling will not occur, so that large pieces of ice are formed inside the ice making cylinder; at the same time, the cavity design on the upper part of the ice making cylinder, on the one hand, prevents the increase or decrease in volume when the ice body is formed in the ice making cylinder from causing damage to the ice making cylinder body, and at the same time, the upper part of the ice making cylinder has a larger horizontal area, which can accommodate more tiny ice bodies. These ice bodies will not contact the side walls of the ice making cylinder when they are on the upper plane inside the ice making cylinder, so the tiny ice bodies will not release heat and condense into one, thereby ensuring the dispersion of the ice body; through the design of the forward and reverse rotation of the turntable, a stable liquid flow direction will not be formed inside the ice making cylinder, further eliminating the possibility of condensation and diffusion of tiny ice bodies. In this way, the small ice bodies formed in the ice making cylinder can be kept in the initial freezing state, forming a state similar to smoothie. After the smoothie is formed for a period of time, the ice making cylinder is removed from the turntable. At this time, the ice making cylinder is in a state of ice and water mixing. The liquid saline can be poured out as needed, and only the smoothie part can be used, or the saline mixed with the smoothie can be used together.
[0020] This naturally condensed ice structure not only has a smaller ice body, but also fits the organs more closely during medical treatment, and has a better refrigeration retention effect. It also has no sharp edges and will not cause damage to the wrapped and refrigerated organs or limbs. At the same time, because this ice body is formed at 0 degrees, it will not cause frostbite when refrigerating living organs or limbs.
[0021] 2. The medical saline ice smoothie making equipment, through the design of the refrigeration module and the cold air port in the cold air cavity, can directly and efficiently transmit the cold air to the ice-making cylinder in the refrigeration cavity. The cold air port and the ice-making cylinder rack on the turntable are set at the same height to ensure that the cold air can evenly cover each ice-making cylinder and avoid local overheating or overcooling. The rotating design of the turntable allows the ice-making cylinder to continuously change its position in the refrigeration cavity, further enhancing the uniformity of the refrigeration effect. Compared with static refrigeration, this dynamic refrigeration method can more effectively reduce the temperature of the saline solution and accelerate the process of reaching the freezing point. The shear force and friction force generated during the rotating stirring process play a key role in the formation and distribution of ice crystals. The action of these forces helps to break larger ice crystal particles into smaller particles and make them more evenly distributed in the saline solution. The ice crystals can be further disrupted by constantly changing the rotation direction of the turntable. The growth direction of the ice is prevented from forming larger ice cubes. This dynamic control process ensures the fineness and uniformity of the smoothie product. The motor drives the turntable to rotate through the connecting rod to realize the automatic stirring and refrigeration of the ice cylinder. This design not only improves the ice-making efficiency, but also reduces the labor intensity of medical staff. At the same time, the direct contact between the cold air outlet and the ice cylinder, and the uniform distribution of cold air in the refrigeration chamber, accelerate the cooling process of the saline solution and shorten the ice-making time. The cylinder cover in the ice cylinder, the part in contact with human hands, and the ice cylinder rack are made of polymer materials. This material has good thermal insulation performance and low-temperature tolerance, and can avoid low-temperature damage when in contact with human hands. The entire ice-making process has a high degree of automation. Medical staff only need to put the ice cylinder into the ice maker, set the parameters and wait. This convenient operation method improves the work efficiency of medical staff.
[0022] 3. The medical saline ice smoothie making equipment, through the rectangular grid hole design of the array on the ice tube rack, not only ensures that the ice tube can directly contact the cold air, but also realizes efficient heat exchange between the cold air and the saline through the optimization of the grid hole area (not less than 70% of the surface area of the ice tube rack and not more than 80%). This design not only ensures sufficient cold air circulation area, but also ensures the structural strength of the ice tube rack. The tube rack is damaged during the rotation process. The gapless design between the ice outer cylinder and the ice inner cylinder further improves the heat exchange efficiency. Since the outer wall surface of the ice inner cylinder is in close contact with the inner wall surface of the ice outer cylinder, the cold air can be more effectively transferred to the saline, which accelerates the cooling process of the saline. Due to the rotation of the ice tube on the turntable, the grid hole The design also promotes the uniform flow of cold air around the ice cylinder, further enhancing the uniformity of the refrigeration effect. The design without gaps between the outer ice cylinder and the inner ice cylinder not only improves the heat exchange efficiency, but also enhances the structural stability and durability of the ice cylinder. Since there is no gap between the two, deformation or damage caused by thermal expansion and contraction is avoided. The design of the grid hole makes it more convenient to clean and maintain the ice cylinder rack and the ice cylinder. Since the grid hole is a through hole, cold air can pass through smoothly, and it is also convenient for cleaning fluid or cleaning tools to enter, thereby effectively cleaning the ice cylinder rack and the inside of the ice cylinder. In addition, the ice cylinder consists of a cylinder cover, an outer ice cylinder and an inner ice cylinder. This modular design is also convenient for disassembly and assembly, further facilitating cleaning and maintenance.
[0023] 4. The medical saline ice smoothie making equipment is designed with mutually matching threads at the barrel openings of the ice-making inner barrel and the ice-making outer barrel. This design allows the two to fit more closely when connected, thereby improving the sealing performance. At the same time, the inner wall of the barrel cover is also provided with threads corresponding to the ice-making outer barrel and the ice-making inner barrel, and a sealing ring is also provided at the barrel opening position in contact with the ice-making inner barrel, further enhancing the sealing effect. This design can prevent cold air from leaking during the refrigeration process and ensure the refrigeration effect. The card blocks in the circumferential array on the side of the barrel cover cooperate with the annular card grooves on the outermost connecting columns of the ice-making barrel rack, so that the ice-making barrel can be stably fixed when placed in the ice-making barrel rack. This design not only prevents the ice-making barrel from shaking or falling off during the rotation process, It also ensures that cold air can be evenly transmitted to the ice cylinder. The protrusion formed by the inward depression of the groove can produce a stirring effect during the rotation, which helps to break up the ice crystal structure that has been formed and disperse it into smaller particles, further improving the quality of the smoothie. The tail fin provided at the tail end of the ice-making outer cylinder not only increases the surface area of the ice-making outer cylinder, but also improves its structural strength through the circumferential array of reinforcement ribs. This design enables the ice-making cylinder to be more stably fixed on the ice-making cylinder frame during rotation, preventing deformation or damage caused by rotation. At the same time, a depression with the same shape as the tail fin is provided in the turntable. This design not only facilitates the placement and fixation of the ice-making cylinder, but also ensures the stability of the ice-making cylinder during rotation.
[0024] 5. The medical saline ice smoothie making equipment, through the breathable bottom plate arranged at the bottom of the refrigeration cavity, allows the cold air in the cold air cavity to flow smoothly into the refrigeration cavity, providing necessary cooling conditions for the ice making process. At the same time, the first radiator under the breathable bottom plate can effectively reduce the temperature of the air in the cold air cavity, ensuring the continuous and stable refrigeration effect. The heat dissipation cavity and the second radiator arranged at the bottom of the ice making machine body constitute an efficient heat dissipation system. The heat generated by the first radiator during the refrigeration process can be quickly discharged through the heat dissipation cavity and the second radiator, avoiding heat The accumulation inside the ice maker ensures the long-term stable operation of the ice maker. The design of the breathable bottom plate not only ensures the smooth circulation of cold air, but also improves the heat exchange efficiency by increasing the contact area with the refrigeration chamber. This allows the cold air to more fully exchange heat with the saline in the ice cylinder, accelerating the formation of ice crystals and the preparation process of smoothies. The heat dissipation cavity is connected front to back and is equipped with a ventilation plate. The dense through holes on the ventilation plate can effectively promote air circulation and heat dissipation. This design not only improves the heat dissipation efficiency, but also avoids the overheating of the ice maker caused by poor heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] See also Figure 1-Figure 6 A medical saline ice smoothie making device comprises an ice making machine body 1, a refrigeration chamber 11 is provided in the ice making machine body 1, an ice making cylinder 12 of sealed saline is installed in the refrigeration chamber 11, the ice making cylinder 12 is a container for making ice smoothies, and cold air is passed into the refrigeration chamber 11. This part of the structure is the same as the principle structure of a traditional refrigerator, and will not be described in detail here.
[0029] In this embodiment, a turntable 13 that rotates forward and reverse is provided in the refrigeration chamber 11, and the ice-making cylinder 12 is detachably assembled relative to the turntable 13. The ice-making cylinder 12 is assembled on the turntable 13. The turntable 13 drives the ice-making cylinder 12 to rotate forward and reverse along a transverse rotation axis. The transverse rotation axis refers to a horizontal rotation axis or a rotation axis with a smaller angle to the horizontal axis. It is necessary to ensure that a transverse cavity is maintained above the physiological saline solution inside the ice-making cylinder 12 during its rotation.
[0030] The medical saline ice smoothie making device comprises an ice machine body 1, the structure of the ice machine body 1 is similar to that of a refrigerator, a refrigeration chamber 11 and a cold air chamber 21 are arranged in the ice machine body 1, the refrigeration chamber 11 is used to place an ice making cylinder 12 filled with saline, a refrigeration module is arranged in the cold air chamber 21, and cold air is passed into the refrigeration chamber 11, a vertical array of turntables 13 are arranged on the inner wall of the refrigeration chamber 11, and the turntables 13 pass through the wall of the refrigeration chamber 11 and pass out from the back of the ice machine body 1, see Figure 4 and Figure 7 The turntable 13 is located in the refrigeration chamber 11 and can rotate, and is provided with an ice-making cylinder rack 132 on which the ice-making cylinder 12 can be placed. The ice-making cylinder rack 132 rotates with the turntable 13. A motor 131 is provided on the back of the ice-making machine body 1. The motor 131 is connected to the rotatable part of the turntable 13 through a connecting rod 134 and drives the rotation. A cold air port 14 connected to the cold air chamber 21 is provided on the inner wall of the side of the refrigeration chamber 11. The cold air port 14 is provided in the same number as the turntable 13 and is provided at the same horizontal height. The cold air chamber 21 is provided with an air pump 22 at the corresponding position of the cold air port 14. When driving the turntable 13 to rotate, the motor 131 changes the rotation direction every 10-15 seconds. During the rotation of the turntable 13, the ice-making cylinder 12 located on the ice-making cylinder rack 132 can contact the cold air ejected from the cold air port 14.
[0031] Medical personnel add a certain amount of physiological saline into the ice-making inner cylinder 123, and the ice-making inner cylinder 123 cannot be completely filled. The ice-making inner cylinder 123 is placed into the ice-making outer cylinder 122, and the cylinder cover 121 is rotated to cover it to achieve sealing and fixation, and the entire ice-making cylinder 12 is placed into the ice-making cylinder frame 132 in the refrigeration chamber 11 of the ice-making machine body 1. A cold air port 14 is provided on the side of the refrigeration chamber 11. The cold air port 14 is arranged at the same height as the ice-making cylinder frame 132 located on the turntable 13, so that cold air can be sprayed onto the ice-making cylinder 12. Because the ice-making cylinder frame 132 is arranged on the rotatable part of the turntable 13, the turntable 13 is driven by the motor 131 and the connecting rod 134 to drive the ice-making cylinder frame 132 to rotate, so that The ice-making cylinder 12 rotates in the refrigeration chamber 11 to receive the cold air ejected from the cold air port 14, and the whole can be evenly cooled to below the freezing point, so that the phase change of water occurs, that is, from liquid to solid. As the temperature decreases, the water molecules in the saline solution begin to slow down their movement and gradually approach the freezing point. When approaching the freezing point, the interaction force between the water molecules increases, and tiny ice crystal nuclei begin to form. When the temperature drops below the freezing point, the ice crystal nuclei begin to grow rapidly to form ice crystals. When the ice-making cylinder 12 is rotated, the shear force and stirring effect generated will destroy the larger ice crystals that have been formed and disperse them into smaller ice crystal particles. The saline solution generates a rotating flow in the cylinder, forming a stirring effect, which helps The ice crystal structure that has been formed is broken and dispersed into smaller particles. When the ice making cylinder 12 rotates in a certain direction, the ice crystals in the saline solution will be distributed with the rotating flow, but long-term rotation in a single direction may cause ice crystals to aggregate in certain areas to form larger ice crystal clumps. Changing the rotation direction can further disrupt the growth direction of the ice crystals and prevent them from forming larger ice cubes. Changing the rotation direction can disrupt this aggregation trend and make the ice crystals more evenly distributed in the cylinder to prevent them from forming larger ice cubes. The shear force and friction force generated by the rotating stirring have an important influence on the formation and distribution of ice crystals. The action of these forces helps to break larger ice crystal particles into smaller particles and make them more even. The ice crystal particles in the saline solution are gradually distributed in the saline solution. As time goes by and the rotation and stirring are continued, the ice crystal particles in the saline solution gradually become small and uniform. When the ice crystal particles are small enough and evenly distributed, a smoothie-like product is formed. The medical staff can take out the ice barrel 12 and pour out the ice smoothie in the barrel for use. In addition, the rotation and stirring can also promote the transfer and distribution of heat, making the temperature in the saline solution more uniform, which helps to avoid abnormal ice crystal growth caused by local overheating or overcooling. In addition, the barrel cover 121 in the ice barrel 12 and the part that contacts the human hand during the use process, and the ice barrel frame 132 are made of polymer materials to avoid injuries caused by low temperature residue when in contact with the human hand.
[0032] To ensure that the physiological saline in the ice making cylinder 12 forms a fine smoothie, the temperature of the refrigeration environment must be low enough to ensure that the physiological saline can quickly reach below the freezing point and undergo a phase change, which is the basic condition for the formation of ice crystals. At the same time, the stability and uniformity of the refrigeration environment are also very important. If the temperature fluctuates too much or is unevenly distributed, it may cause inconsistent growth rates of ice crystals, thereby affecting the fineness of the smoothie. Through the equal height setting of the cold air port 14 and the turntable 13, the cold air ejected from the cold air port 14 can form an airflow flowing around the ice making cylinder, so that the overall temperature drops more evenly. At the same time, when the cold air flows out of the cold air port, it contacts the ice making cylinder 12, increasing the ice making efficiency. Changing the rotation direction not only enhances the stirring effect, but also promotes the dispersion and uniform distribution of ice crystals. This helps prevent ice crystals from excessively gathering in certain areas and forming larger ice cubes. By constantly changing the rotation direction and adjusting parameters such as stirring intensity and time, the growth process and distribution state of ice crystals can be accurately controlled, thereby producing a fine smoothie product that meets the requirements.
[0033] See also Figure 6-Figure 7 The ice-making cylinder frame 132 is provided with rectangular grid holes, which are through holes. The grid hole area is not less than 70% and not more than 80% of the surface area of the ice-making cylinder frame 132, so that the cold air can pass through the ice-making cylinder frame 132 and contact the ice-making cylinder 12. At the same time, the ice-making cylinder 12 has a certain structural strength to avoid damage during the rotation process. The ice-making cylinder 12 is composed of a cylinder cover 121, an ice-making outer cylinder 122, and an ice-making inner cylinder 123. After the physiological saline is added into the ice-making inner cylinder 123, The ice-making outer cylinder 122 is placed in the ice-making outer cylinder 122 and is tightly sealed by the cylinder cover 121. There is no gap between the ice-making outer cylinder 122 and the ice-making inner cylinder 123. The outer wall surface of the ice-making inner cylinder 123 is in close contact with the inner wall surface of the ice-making outer cylinder 122. At the same time, a uniform array of grid holes is provided in the ice-making cylinder frame 132 so that the ice-making cylinder 12 can directly contact the cold air, and there is no gap between the ice-making outer cylinder 122 and the ice-making inner cylinder 123, thereby improving the heat exchange efficiency between the saline solution in the ice-making cylinder 12 and the cold air.
[0034] See also Figure 8-Figure 9 The length of the ice-making inner cylinder 123 is greater than that of the ice-making outer cylinder 122. When the ice-making inner cylinder 123 is placed in the ice-making outer cylinder 122, the opening of the ice-making inner cylinder 123 exceeds the opening of the ice-making outer cylinder 122. The portion of the ice-making inner cylinder 123 exceeding the opening of the ice-making outer cylinder 122 is provided with threads. The opening width of the ice-making outer cylinder 122 is greater than that of the ice-making inner cylinder 123, and threads are provided on the side of the opening. The cylinder cover 121 is in a convex shape, and the inner wall is provided with threads corresponding to the ice-making outer cylinder 122 and the ice-making inner cylinder 123. A sealing ring is provided in the cylinder cover 121 at the position that contacts the opening of the ice-making inner cylinder 123, so that the cylinder cover 121 can seal and fix the ice-making inner cylinder 123 and the ice-making outer cylinder 122.
[0035] See also Figure 10-13The cylinder cover 121 has a card block 1211 arranged in a circular array on the side surface, and the outermost side of the ice-making cylinder frame 132 is provided with a connecting column 1321, and the connecting column 1321 is provided with an annular card groove 133, and the annular card groove 133 is annular in shape as a whole, and is provided with a card groove of the same shape as the card block 1211. When the ice-making cylinder 12 is placed in the ice-making cylinder frame 132, the card block 1211 can be inserted into the card groove of the annular card groove 133, and the tail end of the ice-making outer cylinder 122 is provided with a tail end fin 1221. The tail end fin 1221 is a circular protrusion and is formed by a circumferential array of reinforcing ribs on the side of the protrusion. The turntable 13 is provided with a depression with the same shape as the tail end fin 1221. The side of the ice-making inner cylinder 123 is provided with a groove 1231, which is recessed inwardly. There is a protrusion on the inner wall of the ice-making inner cylinder 123 due to the inward recess of the groove 1231. The coordinated use of the tail end fin 1221 and the block 1211 ensures the synchronous rotation of the ice-making cylinder 12 and the turntable 13.
[0036] See also Figure 1-Figure 5 A breathable bottom plate 111 is provided at the bottom of the refrigeration cavity 11, and the bottom of the breathable bottom plate 111 is connected to the cold air cavity 21. A first radiator 23 is provided below the breathable bottom plate 111. The first radiator 23 is used to cool and reduce the air temperature in the cold air cavity 21. A heat dissipation cavity is provided at the bottom of the ice maker body 1, and a second radiator 24 is provided in the heat dissipation cavity. The heat generated by the first radiator 23 during cooling is discharged from the second radiator 24. The heat dissipation cavity is connected front to back and is provided with a ventilation plate 102, and the ventilation plate 102 is densely covered with through holes.
[0037] See also Fig.14 When the ice making cylinder 12 and the ice making cylinder frame 132 are specifically designed, the cross-sectional structure of the cylinder body can also be designed to be elliptical. During the rotation of the elliptical ice making cylinder 12, the level of the saline solution will change with the rotation, and at the same time, the cavity above the saline solution will change, which reduces the accumulation of ice smoothies during the rotation process, making the produced ice smoothies more delicate. At the same time, due to the change of the saline solution level, its center of gravity ( Fig.14 The black circle in the middle) will also produce an up-and-down displacement, causing it to have an up-and-down shaking effect. In addition, during the formation of physiological saline in the ice making cylinder 12, the ice smoothie is gathered in the upper part of the ice cylinder 12. During the rotation of the elliptical ice making cylinder 12, the shaking effect of the ice smoothie inside is more obvious, which can effectively prevent the ice body inside from condensing into one body and forming larger ice blocks, thereby ensuring the fineness of the ice smoothie formed inside the ice making cylinder 12.
[0038] Working principle: Medical personnel add a certain amount of physiological saline into the ice-making inner cylinder 123, and the ice-making inner cylinder 123 cannot be completely filled. The ice-making inner cylinder 123 is placed into the ice-making outer cylinder 122, and the cylinder cover 121 is rotated to seal and fix it. The entire ice-making cylinder 12 is placed into the ice-making cylinder rack 132 in the refrigeration chamber 11 of the ice-making machine body 1. A cold air port 14 is provided on the side of the refrigeration chamber 11. The cold air port 14 is arranged at the same height as the ice-making cylinder rack 132 located on the turntable 13, so that cold air can be sprayed onto the ice-making cylinder 12. Because the ice-making cylinder rack 132 is arranged on the rotatable part of the turntable 13, the turntable 13 is driven by the motor 131 and the connecting rod 134 to drive the ice-making cylinder rack 132 to rotate, so that the ice-making cylinder 12 rotates in the refrigeration chamber 11 to receive the cold air. The cold air ejected from the opening 14 can evenly cool the whole. At the same time, the ice-making cylinder frame 132 is provided with a uniform array of grid holes so that the ice-making cylinder 12 can directly contact the cold air, and there is no gap between the ice-making outer cylinder 122 and the ice-making inner cylinder 123, which improves the heat exchange efficiency between the physiological saline in the ice-making cylinder 12 and the cold air, and reduces its temperature to below the freezing point, thereby causing a phase change of water, that is, from liquid to solid. As the temperature decreases, the water molecules in the physiological saline begin to slow down their movement and gradually approach the freezing point. When approaching the freezing point, the interaction force between the water molecules increases, and tiny ice crystal nuclei begin to form. When the temperature drops below the freezing point, the ice crystal nuclei begin to grow rapidly to form ice crystals. When the ice-making cylinder 12 is rotated, the shear force and stirring effect generated will destroy the larger ones that have been formed. The ice crystals are dispersed into smaller ice crystal particles. The saline solution generates a rotating flow in the cylinder to form a stirring effect, which helps to break up the ice crystal structure that has been formed and disperse it into smaller particles. When the ice making cylinder 12 rotates in a certain direction, the ice crystals in the saline solution will be distributed along with the rotating flow. However, long-term rotation in a single direction may cause the ice crystals to gather in certain areas to form larger ice crystal agglomerates. Changing the rotation direction can further disrupt the growth direction of the ice crystals and prevent them from forming larger ice cubes. Changing the rotation direction can disrupt this aggregation trend and make the ice crystals more evenly distributed in the cylinder to prevent them from forming larger ice cubes. The shear force and friction force generated by the rotating stirring have an important influence on the formation and distribution of ice crystals. The action of these forces helps to disperse larger ice crystals. Large ice crystal particles are broken into smaller particles and distributed more evenly in the saline solution. As time goes by and the rotation and stirring are continued, the ice crystal particles in the saline solution gradually become small and uniform. When the ice crystal particles are small enough and evenly distributed, a smoothie-like product is formed. Medical staff can take out the ice barrel 12 and pour out the smoothie in the barrel for use. In addition, the rotation and stirring can also promote the transfer and distribution of heat, making the temperature in the saline solution more uniform, which helps to avoid abnormal ice crystal growth caused by local overheating or overcooling. In addition, the barrel cover 121 in the ice barrel 12 and the part that contacts the human hand during the use process, and the ice barrel frame 132 are made of polymer materials to avoid injuries caused by residual low temperature when in contact with the human hand.
