As an efficient freezing method, immersion freezing technology is based on immersing the frozen items in a low-temperature freezing liquid. This technology uses the fact that the heat transfer rate between the liquid and solid (or liquid) interface is much higher than the heat transfer rate between the gas and solid (or liquid) interface, achieving an efficient heat exchange effect of 20 to 40 times. Through direct heat exchange, immersion freezing can achieve rapid freezing of food, and at the same time has significant advantages such as low energy consumption and high freezing quality, showing broad development prospects.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-11 A refrigerator is shown, comprising an equipment body 1, wherein the equipment body 1 is provided with an equipment cavity 11, wherein the equipment body 1 comprises a refrigeration component 12 located in the equipment cavity 11 and in contact with alcohol, an exhaust component 13 located at the top of the equipment cavity 11, a conveying component 14 located in the equipment cavity 11, a condensing circulation component 17 located outside the equipment body 1 and connected to the equipment cavity 11 and the exhaust component 13 respectively, an input component 15 and an output component 16 connected to the equipment cavity 11 and connected to both ends of the conveying component 14 respectively, when materials enter and exit the outside, the equipment cavity 11 remains sealed to prevent alcohol from volatilizing to the outside of the equipment cavity 11.

[0029] The present invention sets a refrigeration component 12 in contact with alcohol in the inner cavity 11 of the device, and sets an exhaust component 13 on the top of the inner cavity 11 of the device, and accelerates the volatilization speed of alcohol through the exhaust component 13, and guides the alcohol vapor to flow upward from the bottom of the inner cavity 11 of the device until it reaches the top, ensuring that the alcohol vapor can cover the surface of the food, which can not only achieve the effect of rapid cooling and shortening the freezing time, but also effectively reduce energy consumption; in addition, the refrigeration component 12 cools the alcohol to below -35°C to achieve the purpose of quick freezing food, and the exhaust component 13 is mainly used to generate a slight negative pressure in the inner cavity 11 of the device to prevent the alcohol from volatilizing to the outside of the inner cavity 11 of the device and causing danger; in addition The present invention also arranges a conveying component 14, an input component 15 and an output component 16 in the device cavity 11, which not only ensures that the food can be automatically input into the device cavity 11 through the input component 15, and the frozen food can be automatically output through the output component 16, but also ensures the stable movement of the food during the freezing process through the conveying component 14, so that each piece of food can be fully frozen; in addition, the present invention also arranges a condensation circulation component 17 connected to the device cavity 11 and the exhaust component 13 on the outside of the device body 1, respectively, to ensure that the alcohol vapor sucked by the exhaust component 13 enters the condensation circulation component 17 and is re-condensed and liquefied for use by the device body 1.

[0030] Specifically, the refrigeration component 12 is located at the bottom of the equipment cavity 11 and is in contact with the liquid alcohol. The liquid alcohol is cooled by the refrigeration component 12, and the volatilization rate of the liquid alcohol is accelerated by the exhaust component 13, thereby prompting the alcohol vapor to move upward. When the alcohol vapor meets the food, the alcohol vapor will adhere to the surface of the food and transfer the cooling temperature to the food, thereby increasing the cooling rate of the food; further, since the temperature at which the alcohol condenses and solidifies is much lower than the freezing temperature of conventional freezing equipment, the equipment body 1 can accelerate the cooling of the food by lowering the temperature without worrying about the problem of alcohol condensation and solidification; further, by arranging the conveying component 14, the input component 15 and the output component 16 in the equipment cavity 11, the food can be automatically frozen through the equipment body 1, and ensure smooth movement throughout the freezing process to ensure that each piece of food can obtain a consistent freezing effect; further, by arranging the input component 15 and the output component 16, it is more convenient for the operator to place the food, and the automatic discharge of the frozen food is realized; further, the conveying component 14 can also adjust the conveying speed according to the freezing requirements of the frozen food, thereby ensuring that the food achieves an ideal freezing effect; further, the use of The alcohol is food grade alcohol. In addition, since the alcohol is volatile, the alcohol will evaporate on its own after the food is discharged from the inner cavity 11 of the device. Furthermore, by arranging a condensation circulation component 17 which is respectively connected to the inner cavity 11 of the device and the exhaust component 13 on the outside of the device body 1, it is ensured that the alcohol vapor sucked by the exhaust component 13 enters the condensation circulation component 17 and is re-condensed and liquefied for use by the device body 1, thereby realizing the recycling of alcohol, effectively reducing energy consumption and reducing resource waste. Furthermore, in some embodiments, the exhaust component 13 is also provided with a device to prevent moisture from entering the condensation circulation component 17 through the exhaust component 13. The moisture drying component can be used to absorb moisture but not alcohol vapor. The moisture drying component uses substances such as calcium chloride or magnesium sulfate. Furthermore, the refrigeration component 12 allows the alcohol to be cooled to below -35°C to achieve the purpose of freezing food faster, and the exhaust component 13 can also generate a slight negative pressure in the device cavity 11 by sucking alcohol vapor, thereby preventing the alcohol vapor from evaporating to the outside of the device cavity 11 and causing danger, thereby achieving a sealed state of the device cavity 11. The sealed state here means that alcohol will not evaporate to the outside of the device cavity 11 through the input component 15 and the output component 16.

[0031] Further, such as Figure 1-11A refrigerator is shown, wherein the conveying component 14 is provided with an input portion 141 connected to the input component 15, an output portion 142 connected to the output component 16, and a conveying portion 143 connecting the input portion 141 and the output portion 142, the conveying portion 143 is located below the input component 15 and the output component 16, the input portion 141 is inclined from the input component 15 toward the conveying portion 143 side, the output portion 142 is inclined from the output component 16 toward the conveying portion 143 side, and the height H1 of the center of the input component 15 from the ground is greater than the height H2 of the center of the output component 16 from the ground.

[0032] The present invention arranges the conveying part 143 below the input component 15 and the output component 16, and the input part 141 is inclined from the input component 15 to the conveying part 143, so as to ensure that the food can move along the inclined input part 141 to the conveying part 143 near the bottom of the equipment cavity 11 after entering the equipment cavity 11, thereby ensuring that the food is in the best freezing area and enhancing the freezing effect; further, by arranging the output part 142 from the output component 16 to the conveying part 143, the frozen food can be lifted along the output part 142 and discharged through the output component 16. This arrangement ensures the height of the output port and provides more collection space for the food after passing through the lower part of the output component 16; further, the present invention ensures the smooth input of the food in the equipment cavity 11 by setting the height H1 of the center of the input component 15 from the ground to be higher than the height H2 of the output component 16. This arrangement effectively utilizes the gravity effect of the food itself, so that the food can naturally slide from a higher position to the conveying component 14 at a lower position, thereby improving the operating efficiency.

[0033] Further, such as Figure 1 A freezer is shown, wherein the conveying assembly 14 is further provided with a material pressing assembly 144 located above the conveying portion 143 .

[0034] The present invention arranges a material pressing assembly 144 above the conveying portion 143, and enables the material pressing assembly 144 to cooperate with the conveying portion 143, the input portion 141 and the output portion 142 to press the food, thereby ensuring the stability of the food during the conveying process. This arrangement not only realizes the stable conveyance of the food and avoids the situation where the food cannot be conveyed according to the predetermined route and speed, but also more effectively ensures that the appropriate intervals are maintained between the foods, so that each piece of food can be evenly exposed to the low-temperature environment, thereby ensuring the freezing effect.

[0035] Further, such as Figure 1-11A refrigerator is shown, wherein the input component 15 includes an input piece 151 rotatably connected to the device body 1, the input piece 151 is provided with a first rotating part 1511 located at both ends and rotatably connected to the device body 1, a plurality of first baffle plates 1512 located on the circumferential side and extending in the radial direction, and a first baffle plate 1513 extending from the first baffle plate 1512 to the rotation direction of the input piece 151 and in the circumferential direction, and the two first baffle plates 1512 enclose a feed cavity 1514.

[0036] The present invention rotatably connects the feed member 151 with the equipment body 1 through the first rotating part 1511, and sets a plurality of independently separated feed chambers 1514 on the feed member 151, so that the operator can place the food in the feed chamber 1514, and as the feed member 151 rotates, the food automatically falls into the input part 141 when it reaches a specific position. This arrangement ensures that the food can fall into the conveying component 14 evenly and dispersedly, effectively avoiding the occurrence of accumulation. Furthermore, the first barrier The plate 1512 is provided with a first baffle plate 1513 extending circumferentially in the direction of rotation of the feed piece 151, so that the first baffle plate 1512 can cover most of the area of ​​the feed chamber 1514, effectively preventing the food from escaping from the feed chamber 1514 due to centrifugal force during the rotation of the feed piece 151. At the same time, when the feed chamber 1514 rotates to the side of the input part 141, the food can smoothly pass through the unblocked part to escape from the feed chamber 1514 and reach the input part 141, thereby improving the reliability of the entire process.

[0037] Further, such as Figure 1-11 A refrigerator is shown, wherein the input component 15 also includes a first shielding component 152 arranged on the outside of the feed piece 151 and connected to the equipment body 1, the first shielding component 152 is used to shield the feed cavity 1514, the first shielding component 152 is located on one side of the input part 141 and a first avoidance hole 1521 is also provided on the opposite side of the input part 141, and the cross-section of the feed piece 151 is circular.

[0038] The present invention provides a first shielding component 152 located outside the feeding member 151 and surrounding the feeding member 151, and the first shielding component 152 is located on one side of the input part 141 and a first avoidance hole 1521 is provided on the opposite side of the input part 141. This arrangement not only ensures that the operator can normally put the food into the feeding cavity 1514 from the opposite side of the input part 141, but also ensures that the food can smoothly leave the feeding cavity 1514 from the side of the input part 141 and reach the input part 141; further, the arrangement of the first avoidance hole 1521 effectively shields the rest of the feeding cavity 1514. 14, so that food can only enter and exit from the two designated feeding chambers 1514. This arrangement not only further prevents the food from leaving the feeding chamber 1514 prematurely due to the centrifugal force during the rotation of the feeding piece 151, but also reduces the possibility of external air and pollutants entering the equipment cavity 11 through the remaining feeding chambers 1514, thereby maintaining the dryness and cleanliness of the equipment cavity 11 and improving food safety and sanitary conditions; further, the cross-section of the feeding piece 151 is circular, so that the feeding piece 151 can occupy less space when rotating, thereby effectively reducing the overall space of the equipment body 1.

[0039] Further, such as Figure 1-11 A refrigerator is shown, wherein the input component 15 further includes an expansion component 153 connected to the first shielding component 152 and the device body 1 respectively, and the expansion component 153 is provided with an expansion cavity 1531 connected to the device cavity 11.

[0040] The utility model provides an expansion component 153 connected to the first shielding component 152 and the device body 1, and provides an expansion cavity 1531 in the expansion component 153, thereby providing sufficient space for the process of food reaching the input part 141 from the feeding cavity 1514. When the food rotates to the side of the input part 141 through the feeding piece 151, the food will fall out of the feeding cavity 1514 to the input part 141, or when the feeding piece 151 rotates at a faster speed, the food will even be thrown out of the feeding cavity 1514 to the input part 141 in a certain parabola, and the expansion cavity 1531 ensures that there is enough space for the food to fall into the input part 141, thereby avoiding the collision of food due to insufficient space.

[0041] Further, such as Figure 1-11 A refrigerator is shown, wherein the output component 16 includes a discharge piece 161 rotatably connected to the device body 1, the discharge piece 161 is provided with a second rotating part 1611 located at both ends and rotatably connected to the device body 1, a plurality of second baffle plates 1612 located on the circumferential side and extending in the radial direction, and a second baffle plate 1613 extending from the second baffle plate 1612 to the rotation direction of the discharge piece 161 and in the circumferential direction, and the two second baffle plates 1612 enclose a discharge cavity 1614.

[0042] The present invention connects the discharging member 161 to the equipment body 1 through the second rotating part 1611, and sets a plurality of independently separated discharging chambers 1614 on the discharging member 161, so that when the food reaches the discharging member 161 from the output part 142, the food can be separated separately through the discharging chamber 1614, and with the rotation of the discharging member 161, the food is transported to the outside of the equipment cavity 11 for further collection or directly enters the next process; further, the second baffle plate 1612 is provided with a rotation direction of the discharging member 161 and The second baffle plate 1613 extending in the circumferential direction enables the second blocking plate 1612 to cover most of the area of ​​the discharge chamber 1614, effectively preventing the food from prematurely escaping from the discharge chamber 1614 when the discharge chamber 1614 rotates to the outside of the equipment cavity 11, resulting in the food not being able to accurately fall into the predetermined position. At the same time, when the discharge chamber 1614 rotates to the side of the output part 142, the food can smoothly enter the discharge chamber 1614 through the unblocked part and be transported to the outside of the equipment cavity 11, thereby improving the reliability of the entire process.

[0043] Further, such as Figure 1-11 A freezer is shown, wherein the output component 16 also includes a second shielding component 162 arranged on the outside of the discharge piece 161 and connected to the equipment body 1, the second shielding component 162 is used to shield the discharge cavity 1614, the second shielding component 162 is located on one side of the output part 142 and a second avoidance hole 1621 is also provided on the opposite side of the output part 142, and the cross-section of the discharge piece 161 is circular.

[0044] The present invention provides a second shielding component 162 located outside the material discharging member 161 and surrounding the material discharging member 161, and the second shielding component 162 is located on one side of the output portion 142 and a second avoidance hole 1621 is provided on the opposite side of the output portion 142. This arrangement not only ensures that the food can smoothly fall into the material discharging member 161 from the side of the output portion 142, but also ensures that the food can escape from the material discharging cavity 1614 from the opposite side of the output portion 142; further, the arrangement of the second avoidance hole 1621 effectively blocks the rest of the material discharging cavity 1614, so that the food can only The food enters and exits from the two designated discharge chambers 1614. This arrangement not only further prevents the food from prematurely escaping from the discharge chamber 1614 due to the centrifugal force during the rotation of the discharge piece 161, but also reduces the possibility of outside air and pollutants entering the equipment cavity 11 through the remaining discharge chambers 1614, thereby maintaining the dryness and cleanliness of the equipment cavity 11 and improving food safety and sanitary conditions; further, the discharge piece 161 is circular in cross-section, so that the discharge piece 161 occupies less space when rotating, thereby effectively reducing the overall space of the equipment body 1.

[0045] Further, such as Figure 1-11In the freezer shown in the figure, the device body 1 is located on one side of the condensing circulation component 17 and is also provided with a liquid inlet 111 which is connected to the device inner cavity 11 and the condensing circulation component 17 respectively; the condensing circulation component 17 is provided with a connecting component 171 which is connected to the exhaust component 13, and a ventilation component 173 for discharging or inhaling gas.

[0046] The present invention provides a liquid inlet 111 which is respectively connected to the device inner cavity 11 and the condensation circulation component 17 on one side of the device body 1 located at the condensation circulation component 17, so that the condensation circulation component 17 can be connected to the device inner cavity 11 through the liquid inlet 111, ensuring that the condensed liquid alcohol can flow back to the device inner cavity 11 for reuse by the device body 1; further, by providing a connecting component 171 connected to the exhaust component 13 on the condensation circulation component 17, the connecting component 171 can guide the alcohol vapor extracted by the exhaust component 13 into the condensation circulation component 17; further, by providing a ventilation component 173 for discharging or inhaling gas on the condensation circulation component 17, the condensation circulation component 17 can maintain the air pressure balance inside the condensation circulation component 17 through the ventilation component 173; further, the ventilation component 173 also allows the operator to pour liquid alcohol into the ventilation component 173, thereby replenishing the liquid alcohol into the device inner cavity 11, effectively simplifying the steps for the operator to replenish alcohol.

[0047] Further, such as Figure 1-11 The freezing method shown comprises the following steps: S1, the refrigeration component 12 is in contact with liquid alcohol, and the liquid alcohol is accelerated to volatilize through the exhaust component 13 and causes the alcohol vapor to rise; S2, the input component 15 transports the food to the conveying component 14 to contact with the alcohol vapor for cooling, and outputs the food through the output component 16; S3, part of the alcohol vapor is absorbed by the exhaust component 13 and enters the condensation circulation component 17 for liquefaction treatment.

[0048] The present invention provides a freezing method for a freezer, the core of which is to achieve a high-efficiency freezing effect of food and effectively reduce resource waste by cooperating with a refrigeration component 12, an exhaust component 13, a condensation circulation component 17, an input component 15, a conveying component 14 and an output component 16, and by using alcohol as a freezing medium; further, in the freezing method, first, the input component 15 conveys the food to be frozen to the conveying component 14, and the refrigeration component 12 contacts with liquid alcohol in the equipment cavity 11, and accelerates the volatilization of alcohol through the exhaust component 13, so that the alcohol vapor can rise and contact the food on the conveying component 14, quickly covering the surface of the food, thereby This setting can achieve the effect of rapid cooling, and achieves a faster and more uniform freezing effect than traditional freezing methods, thereby effectively shortening the freezing time; further, after the food is effectively frozen, it is output from the device cavity 11 through the output component 16, and the alcohol vapor is absorbed by the exhaust component 13 and enters the condensation circulation component 17 for liquefaction treatment, and then the liquefied alcohol can be reused by the device body 1. This setting ensures the efficient utilization of alcohol as a cooling medium, which not only effectively reduces the waste of resources, but also effectively prevents alcohol from being discharged into the air and polluting the environment; further, the temperature of the device cavity 11 in the present invention is minus 18°C ​​to minus 30°C.

[0049] like Figure 1-8 As shown, the refrigerator embodiment of the present invention is as follows: Embodiment 1: In this embodiment, a freezer is provided, the purpose of which is to improve the freezing efficiency of food and reduce the energy consumption of the freezer. The freezer is mainly composed of a device body 1, which is provided with a device cavity 11, and further includes a refrigeration component 12 located at the bottom of the device cavity 11, an exhaust component 13 located at the top of the device cavity 11, and a condensation circulation component 17 located outside the device body 1 for condensing liquefied alcohol vapor for reuse by the device body 1. Liquid alcohol in contact with the refrigeration component 12 is also placed at the bottom of the device cavity 11.

[0050] When the freezer is started, the refrigeration component 12 located at the bottom of the equipment cavity 11 starts to operate, cools the liquid alcohol, accelerates the volatilization of the alcohol through the exhaust component 13, and absorbs the alcohol vapor to the top of the equipment cavity 11, so that the alcohol vapor is fully in contact with the surface of the food, achieving rapid cooling of the food, greatly shortening the freezing time. Among them, because the temperature at which alcohol condenses and solidifies is much lower than the freezing temperature of conventional freezing equipment, there is no need to worry that the alcohol will solidify within this temperature range, ensuring the heat exchange effect. In addition, in this embodiment, the temperature of the equipment cavity 11 is minus 18°C ​​to minus 30°C.

[0051] In addition, the alcohol vapor collected by the exhaust component 13 enters the condensation circulation component 17 for liquefaction treatment, and the alcohol after the liquefaction is temporarily stored in the device cavity 11 or directly used by the device body 1 In addition, in order to ensure that the food can smoothly enter, pass through and leave the device cavity 11, the device body 1 in this embodiment is also provided with a conveying component 14 located in the device cavity 11, and an input component 15 and an output component 16 respectively located at both ends of the device body 1 and connected to both ends of the conveying component 14, so that the food can be automatically delivered into the device cavity 11 through the input component 15. Among them, the conveying component 14 transports the food at a preset speed so that each piece of food can be evenly exposed to the alcohol vapor to obtain a consistent freezing effect. In addition, the conveying component 14 can also adjust the conveying speed according to different freezing requirements to achieve an ideal freezing effect. When the food is frozen, it will be automatically discharged through the output component 16. The whole process does not require manual intervention, which improves the convenience of operation. Furthermore, the refrigeration component 12 allows the alcohol to be cooled to below -35°C to achieve the purpose of freezing food faster, and the exhaust component 13 can also generate a slight negative pressure in the device cavity 11 by sucking alcohol vapor, preventing the alcohol vapor from evaporating to the outside of the device cavity 11 and causing danger, thereby achieving a sealed state of the device cavity 11. The sealed state here means that alcohol will not evaporate to the outside of the device cavity 11 through the input component 15 and the output component 16.

[0052] In addition, since food-grade alcohol is used in this embodiment, its volatility means that once the food leaves the inner cavity 11 of the device, the residual alcohol will evaporate naturally and will not contaminate the food or affect the taste.

[0053] Embodiment 2: The present invention includes the features of embodiment 1, and differs from embodiment 2 in that the conveying component 14 in this embodiment is provided with an input portion 141 connected to the input component 15, an output portion 142 connected to the output component 16, and a conveying portion 143 connecting the input portion 141 and the output portion 142. By arranging the conveying part 143 below the input component 15 and the output component 16, and the input part 141 is inclined from the input component 15 to the conveying part 143, it is ensured that after the food enters the equipment cavity 11, it can move along the inclined input part 141 to the conveying part 143 near the bottom of the equipment cavity 11, thereby ensuring that the food is in the best freezing area and enhancing the freezing effect; in addition, by arranging the output part 142 from the output component 16 to the conveying part 143, the frozen food can be lifted along the output part 142 and discharged through the output component 16. This arrangement ensures the height of the output port and provides more collection space for the food after passing through the lower part of the output component 16; in addition, this embodiment effectively utilizes the gravity effect of the food itself by setting the height H1 of the center of the input component 15 from the ground to be higher than the height H2 of the output component 16, so that the food can naturally slide from a higher position to the conveying component 14 at a lower position, ensuring the smooth input of the food in the equipment cavity 11.

This arrangement not only further prevents food from prematurely escaping from the discharge chamber 1614 due to centrifugal force during the rotation of the discharge member 161, but also reduces the possibility of outside air and pollutants entering the equipment cavity 11 through the remaining discharge chambers 1614, thereby maintaining the dryness and cleanliness of the equipment cavity 11 and improving food safety and sanitary conditions; in addition, the discharge member 161 is circular in cross-section, so that the discharge member 161 can occupy less space when rotating, thereby effectively reducing the overall space of the equipment body 1.

[0060] Embodiment nine: The present invention includes the features of Embodiment 8, and is different from Embodiment 8 in that, in this embodiment, a liquid inlet 111 is provided on one side of the condensation circulation component 17 of the device body 1, which is connected to the device inner cavity 11 and the condensation circulation component 17 respectively, so that the condensation circulation component 17 can be connected to the device inner cavity 11 through the liquid inlet 111, thereby ensuring that the condensed liquid alcohol can flow back to the device inner cavity 11 for reuse by the device body 1; in addition, a connecting component 171 connected to the exhaust component 13 is provided in the condensation circulation component 17, so that the connecting component 171 can guide the alcohol vapor extracted by the exhaust component 13 into the condensation circulation component 17; then, a ventilation component 173 for discharging or inhaling gas is provided in the condensation circulation component 17, so that the condensation circulation component 17 can maintain the air pressure balance inside the condensation circulation component 17 through the ventilation component 173; in addition, the ventilation component 173 also allows the operator to pour liquid alcohol into the ventilation component 173, thereby replenishing the liquid alcohol into the device inner cavity 11, effectively simplifying the steps for the operator to replenish alcohol.

[0061] Embodiment ten: The present invention includes the features of Embodiment 9, and is different from Embodiment 9 in that the condensation circulation component 17 is only used for condensing alcohol vapor and collecting the condensed and liquefied alcohol.

[0062] Embodiment eleven: The present invention includes the features of embodiment nine, and differs from embodiment nine in that the condensation circulation component 17 is further provided with a liquid outlet component 172 connected to the liquid inlet 111, and the liquid outlet component 172 is provided with a backflow prevention component 1721 to prevent alcohol in the equipment inner cavity 11 from entering the condensation circulation component 17 through the liquid outlet component 172.

[0063] Embodiment 12: The present invention includes the features of Example 11, and differs from Example 11 in that the device body 1 also includes a first dehumidification device 154 located in the expansion cavity 1531, and a second dehumidification device 18 close to the output component 16, so as to reduce the moisture in the external air after entering the device cavity 11 through the input component 15 and the output component 16, and reduce the problem of moisture in the air freezing in the device cavity 11.

[0064] Embodiment 13: The present invention includes the features of the twelve embodiment, and the difference from the twelve embodiment is that a moisture drying component is further provided in the exhaust component 13 to prevent moisture from entering the condensation circulation component 17 through the exhaust component 13, so as to prevent moisture from freezing and clogging in the connection component 171. In addition, the temperature in the condensation circulation component 17 is about minus 30 degrees, so that part of the alcohol can condense. In addition, the moisture drying component can be used to absorb moisture but not alcohol vapor. The moisture drying component can use materials such as calcium chloride, magnesium sulfate or color-changing silica gel. The use of color-changing silica gel can facilitate observation of whether the silica gel needs to be replaced, and the color-changing silica gel can be reused after drying.

[0065] Embodiment 14: This embodiment proposes a freezing method. One of the existing freezing methods is: the existing freezing equipment usually uses a compressor refrigerant to create a low temperature environment, so that the food is gradually cooled until it is completely frozen. However, the existing freezing method needs to keep the air dry to prevent the moisture in the air from freezing, etc., resulting in low temperature transfer efficiency with the food, making the freezing process of the food take a long time. If you try to speed up the cooling speed by lowering the temperature of the freezing equipment, it will increase energy consumption, thereby increasing operating costs.

[0066] The freezing method of the present invention is as follows: the refrigeration component 12 and the liquid alcohol are both located at the bottom of the equipment cavity 11, and the liquid alcohol soaks the refrigeration component 12. When the equipment is running, the temperature of the equipment cavity 11 is between -18°C and -30°C. The volatilization rate of the liquid alcohol at the bottom of the equipment cavity 11 is accelerated by the exhaust component 13 at the top of the equipment cavity 11, so that the alcohol vapor rises from the bottom of the equipment cavity 11 to the top of the equipment cavity 11. When the alcohol vapor reaches the top of the equipment cavity 11, it will be sucked in by the exhaust component 13 and transported to the condensation circulation component 17 to liquefy the alcohol vapor, so that it can be reused by the equipment.

[0067] During the operation of the device, when the food is transported from the input assembly 15 to the conveying assembly 14 located in the inner cavity 11 of the device, the rising alcohol vapor will contact the food and exchange heat with it, thereby accelerating the cooling speed of the food. The user can set the conveying speed of the conveying assembly 14 according to the cooling time required by the user to ensure that the food is fully cooled when it reaches the output assembly 16. After cooling, the food is output through the output assembly 16.

[0068] Embodiment 15: The difference between the freezing method in this embodiment and that in Embodiment 14 is that after the alcohol vapor is liquefied by the condensation circulation component 17 , it can automatically flow back to the inner cavity 11 of the device from the condensation circulation component 17 .

[0069] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
