Description

Technical Field

[0002] Carbon dioxide hydrate is an inclusion compound formed by a hydrogen bond network between water molecules and the guest molecule carbon dioxide. Traditionally, carbon dioxide hydrates require low temperature and high pressure to form, and are primarily targeted at applications in carbon capture and storage technologies using the hydrate method. Applications in the food industry require milder temperature and pressure conditions for preparation and storage, and must meet food safety standards and be non-hazardous. Currently, sparkling ice (carbon dioxide hydrate) has not been applied to beverages or foods. Although various liquid carbonated beverages and other bubbling beverages are currently available on the market, such as sparkling water and soda water, these are all achieved by directly adding carbon dioxide gas or sodium bicarbonate.

[0017] In a second aspect, a method for preparing bubble ice is provided, which is performed using the preparation device described in the first aspect, comprising the following steps:

[0018] (1) injecting a predetermined amount of water-containing liquid into each grid of the grid in the bubble ice generating chamber through a liquid injection system according to a predetermined gas-water volume ratio, thereby maintaining the temperature in the bubble ice generating chamber at a first temperature;

[0019] (2) starting the disturbance system and injecting carbon dioxide gas of a predetermined pressure into the bubble ice generating chamber through the gas source supply system, wherein the water-containing liquid and the carbon dioxide gas generate bubble ice under the disturbance of the disturbance system at the second temperature;

[0020] (3) After the bubble ice is generated, the air release valve is opened, and the bottom of the bubble ice generating chamber is opened to connect the bubble ice generating chamber with the ice storage chamber so that the bubble ice enters the ice storage chamber.

[0021] Preferably:

[0022] When the disturbance system is a stirring device and the preparation device further includes a compression system, in step (2), after carbon dioxide gas of a predetermined pressure is injected into the bubble ice generation chamber through the gas source supply system, the gas source supply system is closed after the carbon dioxide is dissolved in water and equilibrium is reached, and bubble ice is generated at the second temperature; in step (3), the bubble ice is compressed into bubble ice of smaller volume through the compression system and then pushed into the ice storage chamber.

The present invention proposes a bubble ice preparation scheme with both continuous bubble release and low temperature maintenance functions to solve the problem of deterioration of taste of existing bubble beverages after secondary use. The present invention studies and prepares bubble ice (also known as jumping ice, exploding ice, etc.) with high carbon dioxide content, rich bubble content and small volume. By optimizing the preparation process and parameters, the production and storage conditions of bubble ice are reduced, and the bubble ice can be produced safely and efficiently under mild conditions. The self-protection effect of carbon dioxide hydrates is used to achieve long-term refrigeration and bubble supply of bubble ice. When used, bubble ice has the advantages of both refrigeration and large bubble production. The bubble ice itself also has a self-protection effect and is not easy to melt. Combined with food or beverages, it can enrich the taste, provide consumers with more choices, and bring innovation to the food industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present invention is further described below through various examples.

[0051] Example 1

[0052] like Figure 1-Figure 3 As shown, the bubble ice preparation device includes a bubble ice generation system, an air supply system, a liquid injection system, a circulating refrigeration system, a compression system, a data acquisition and control system, an air release valve, an ice storage chamber, a stirring device 17, a temperature sensor and a pressure sensor.

[0053] The bubble ice making system includes a bubble ice making chamber 1 and a mesh grid 2. The mesh grid 2 is connected to the side wall of the bubble ice making chamber 1. Each grid of the mesh grid provides a space for bubble ice making. The bottom of the mesh grid 2 is at a predetermined distance from the bottom 15 of the bubble ice making chamber 1 (this distance is preferably 2-3 cm so as not to affect stirring by a stirring device and compression of the bubble ice by a subsequent compression system). The stirring device 17 is disposed at the bottom 15 of the bubble ice making chamber 1 and is located between the bottom of the mesh grid 2 and the bottom 15 of the bubble ice making chamber 1. The ice storage chamber 5 is located below the bottom 15 of the bubble ice making chamber 1. The bottom of the bubble ice making chamber 1 can be opened and closed to connect or seal the bubble ice making chamber 1 with the ice storage chamber 5. When the bottom 15 of the bubble ice generating chamber 1 is closed so that the bubble ice generating chamber 1 and the ice storage chamber 5 are in a sealed state, bubble ice is prepared. When the bottom 15 of the bubble ice generating chamber 1 is opened so that the bubble ice generating chamber 1 and the ice storage chamber 5 are in a connected state, the bubble ice cubes compressed by the compression system enter the ice storage chamber 5.

[0054] Each grid of the grid is open at the top and bottom and has a predetermined depth. A water-containing liquid is injected into the grid of the bubble ice generation chamber in a measured amount through a liquid injection system to confine the formation of bubble ice primarily within the grid, facilitating the subsequent compression system to compress the generated bubble ice.

[0055] Preferably, the grid is made of food-grade stainless steel, such as 304 stainless steel. The grid can be composed of a plurality of rectangular grids (open at the top and bottom) of a predetermined depth. Preferably, both the aqueous liquid and the carbon dioxide gas are edible, so that the bubble ice produced by the production apparatus of the present invention can be directly used in food or beverages.

[0056] Preferably, the stirring device 17 is connected to the middle area of ​​the bottom of the bubble ice generating chamber 1 to disturb the substances in the entire bubble ice generating chamber 1. When the bottom of the bubble ice generating chamber 1 is controlled to open and close, the stirring device 17 and the bottom of the bubble ice generating chamber 1 can be opened and closed as a whole to facilitate the subsequent compression and delivery of the bubble ice to the ice storage chamber.

[0057] Preferably, the preparation device further comprises a visualization window 3, which is provided on the side wall of the bubble ice forming chamber 1 at a position corresponding to the grid (covering the grid), so that the formation of bubble ice solids in the grid can be observed through the visualization window.

[0058] Preferably, the preparation apparatus further comprises a monitoring device (such as a camera, not shown in the figure), which is located outside the visualization window and is used to take pictures of the bubble ice production chamber.

[0059] The gas supply system is connected to the bubble ice making chamber 1 and is used to supply carbon dioxide gas at a predetermined pressure and volume to the bubble ice making chamber 1. Preferably, the gas supply system includes a carbon dioxide cylinder 6, a gas valve 12, and a pressurizing device 7 (preferably a pressurizing pump). The carbon dioxide cylinder 6 is connected to the bubble ice making chamber 1 via the gas valve 12 and the pressurizing device 7. Preferably, the pressure of the carbon dioxide cylinder 6 when fully loaded does not exceed 6 MPa, and the volume of the carbon dioxide cylinder 6 does not exceed half of the total volume of the preparation apparatus. The gas cylinder loading area has a fixed position and a quick-release valve, allowing for quick and easy replacement of the carbon dioxide cylinder if it runs out of gas. The connection between the gas cylinder and the gas pipeline is controlled by a gas valve 12. The pressurizing device 7 is connected to the gas pipeline. If the pressure in the carbon dioxide cylinder 6 does not meet the required injection pressure, the pressurizing device 7 automatically opens to increase the gas in the gas pipeline to the required pressure and then closes, ensuring that the carbon dioxide gas is injected into the bubble ice making chamber 1 at the predetermined pressure during the bubble ice preparation process.

[0060] The liquid injection system is connected to the bubble ice making chamber and is used to supply a predetermined volume of aqueous liquid to the bubble ice making chamber. Preferably, the liquid injection system includes a liquid bottle 8, a liquid valve 14, and a liquid injection device 9 (preferably, a liquid injection pump). The liquid bottle 8 is connected to the bubble ice making chamber 1 via the liquid injection device 9 and the liquid valve 14. The aqueous liquid is delivered to the bubble ice making chamber by increasing a certain pressure, and the system automatically closes when the predetermined volume is reached.

[0061] The circulating refrigeration system is connected to the bubble ice production chamber and the ice storage chamber, respectively, and is used to control the bubble ice production chamber and the ice storage chamber at a predetermined temperature. Preferably, the circulating refrigeration system adopts a coil circulation refrigeration method, and the cold coil 10 in the circulating refrigeration system is attached to the surrounding walls of the bubble ice production chamber 1 and the ice storage chamber 5. Of course, the circulating refrigeration system also has the necessary compressor and fan to dissipate the heat generated by refrigeration.

[0062] The compression system is connected to the top of the bubble ice production chamber and is used to compress the bubble ice after it is produced. Preferably, the compression system 4 includes a drive device 41 and a compression push rod 42 connected to the drive device 41. The compression push rod 42 extends through the top of the bubble ice production chamber 1 and is driven by the drive device 41 to move up and down within the bubble ice production chamber 1. The bottom end 421 of the compression push rod 42 is flexible and has a shape that matches the mesh grid 2. For example, if the mesh grid is rectangular, the bottom end of the compression push rod 42 can also be shaped like a rectangular grid, so as to accurately compress the volume of the bubble ice in each mesh grid.

[0063] The air release valve 11 is connected to the bubble ice generating chamber 1. Before compression, the excess carbon dioxide in the bubble ice generating chamber 1 is released into the ice storage chamber 5 through the air release valve 11. On the one hand, the pressure is released to ensure that the compression push rod 42 is quickly pushed downward and each ice cube in the mesh grid is pushed into the ice storage chamber according to the flexible module at the bottom end of the compression push rod 42; on the other hand, the excess carbon dioxide released into the ice storage chamber can prevent the bubble ice from decomposing.

[0064] The temperature sensor (not shown) and the pressure sensor (not shown) are both connected to the bubble ice generating chamber and are used to detect the temperature and pressure in the bubble ice generating chamber.

[0065] The data acquisition and control system 13 is used to collect data from various sensors and coordinate the operation of various components. Specifically, the data acquisition and control system 13 can be connected to the bubble ice generation system, air supply system, liquid injection system, circulating refrigeration system, stirring device, air release valve, compression system, temperature sensor and pressure sensor to coordinate and control their operation. In this example, more specifically:

[0066] The data acquisition and control system collects data from temperature sensors, pressure sensors, etc., and dynamically controls the operation of other components based on the collected data.

[0067] The data acquisition and control system is connected to the driving device 41 in the compression system, and is used to start the compression system to compress the generated bubble ice after the bubble ice is generated.

[0068] The data acquisition and control system is respectively connected to the gas valve and the pressurizing device in the gas supply system, and is used to control the gas supply system to inject or stop injecting carbon dioxide gas into the bubble ice forming chamber 1 .

[0069] The data acquisition and control system is respectively connected to the liquid valve in the liquid injection system and the liquid injection device, and is used to control the liquid injection system to inject or stop injecting the water-containing liquid into the bubble ice forming chamber 1 .

[0070] The data acquisition and control system is connected to the bottom of the bubble ice generating chamber to control the opening and closing of the bottom of the bubble ice generating chamber and the stirring device as a whole to make the bubble ice generating chamber 1 and the ice storage chamber 5 closed or connected.

[0071] The data acquisition and control system is connected to the air release valve to control the opening or closing of the air release valve.

[0072] The data acquisition and control system is connected to the stirring device to control the operation of the stirring device.

[0073] The data acquisition and control system is connected to the circulating refrigeration system to control the operation of the circulating refrigeration system.

[0074] Using the above-mentioned bubble ice making device, a method for making bubble ice includes the following steps:

[0075] (1) A predetermined amount of water-containing liquid is injected into each grid of the grid in the bubble ice generating chamber through a liquid injection system according to a predetermined gas-water volume ratio (i.e., the volume ratio of carbon dioxide gas to water in the water-containing liquid), and the temperature in the bubble ice generating chamber is maintained at a first temperature (for example, the first temperature may be room temperature or may be equal to a second temperature).

[0076] (2) Turn on the stirring device and inject carbon dioxide gas of a predetermined pressure into the bubble ice generating chamber through the gas supply system. After the carbon dioxide is dissolved in the water to a equilibrium state, turn off the gas supply system.

[0077] (3) at the second temperature, under the stirring of the stirring device, the water-containing liquid and the carbon dioxide gas generate bubble ice; in step (3), by dissolving saturated carbon dioxide and gaseous carbon dioxide under severe mechanical disturbance conditions, the bubble ice is promoted to rapidly nucleate and generate in large quantities. The bubble ice generation method of the present invention cleverly adopts a method of mechanical disturbance coupled with a grid confined space, so that the bubble ice can rely on the wall surface to quickly climb the wall and generate within the specified grid area.

[0078] (4) After the bubble ice is generated, the air release valve is opened, the bubble ice is compressed into a smaller volume of bubble ice through the compression system, and the bottom of the bubble ice generating chamber is opened to connect the bubble ice generating chamber with the ice storage chamber so that the bubble ice is pushed to the ice storage chamber.

[0079] The content of bubble ice prepared by the preparation device of the present invention is 10-50 v / v, and the generation time does not exceed 15 minutes.

[0080] Preferably, the predetermined gas-liquid volume ratio in step (1) is 1:1 to 5:1. The selected gas-liquid ratio should not be too low or too high. A too low ratio will affect the final yield of bubble ice, while a too high ratio will affect the gas content in the bubble ice.

[0081] Preferably, the first temperature is 0-20°C;

[0082] Preferably, the predetermined pressure in step (2) is not higher than 4 MPa.

[0083] Preferably, the rotation speed of the stirring device in step (2) and step (3) is independently 500 r / min to 1000 r / min.

[0084] Preferably, the second temperature in step (3) is 0-5°C.

[0085] Preferably, in step (2), when the pressure in the bubble ice generating chamber is at a constant pressure within the range of 1-3 MPa and the pressure drop is less than 0.01 MPa, it is considered that the dissolution equilibrium of carbon dioxide in water is reached.

[0086] Preferably, in step (3), the formation of bubble ice is determined by at least one of visual observation, pressure drop (pressure drop rate greater than 0.2 MPa / min) and temperature fluctuation (temperature fluctuation greater than 1°C). If the formation is slow or the amount of bubble ice generated is small (preferably, if the amount of bubble ice generated within 10 minutes is less than 10 v / v, it is considered that the formation is slow or the amount of bubble ice generated is small), the rotation speed of the stirring device is increased and / or the temperature is lowered to accelerate the formation of bubble ice.

[0087] Preferably, in step (4), when the pressure drop rate in the bubble ice generating chamber is less than 0.01 MPa / h, or when the amount of bubble ice generated is ≥10 v / v, it is considered that the bubble ice generation is completed.

[0088] Preferably, steps (1) to (4) are repeated to continuously generate bubble ice.

[0089] In the present invention, the aqueous liquid can be edible, for example, pure water, or water with other edible additives (such as sugars, amino acids, various beverages, beer, etc.). Edible liquids (such as various beverages, beer, etc.) can also be directly used as the medium for generating bubble ice, as long as the gas-water volume ratio meets the predetermined requirements during the preparation of the bubble ice.

[0090] In the present invention, the carbon dioxide gas can be edible, and its purity is ≥99.99%. The carbon dioxide must be in a gaseous state, and its temperature and pressure conditions are relatively harsh and must be lower than the liquefied and supercritical conditions. The temperature in the carbon dioxide cylinder 6 is not higher than 293K, and the maximum pressure is not higher than 4MPa.

[0091] Example 2

[0092] like Figure 4 As shown, the bubble ice production device includes a bubble ice generation system, an air supply system, a liquid injection system, a circulating refrigeration system, a data acquisition and control system, a gas release valve, an ice storage chamber, a bubbling device 16, a temperature sensor, and a pressure sensor. Note: In Example 2, components identical to those in Example 1 are denoted by the same reference numerals.

[0093] The bubble ice making system includes a bubble ice making chamber 1 and a mesh grid 2. The mesh grid 2 is connected to the side wall of the bubble ice making chamber 1. Each grid of the mesh grid defines a space for bubble ice making. The bottom of the mesh grid 2 is movably connected to the bottom 15 of the bubble ice making chamber 1. The ice storage chamber 5 is located below the bottom 15 of the bubble ice making chamber 1. The bottom of the bubble ice making chamber 1 can be opened and closed to allow the bubble ice making chamber 1 and the ice storage chamber 5 to be connected or closed. When the bottom 15 of the bubble ice making chamber 1 is closed, bubble ice is prepared. When the bottom 15 of the bubble ice making chamber 1 is opened, allowing the bubble ice making chamber 1 and the ice storage chamber 5 to be connected, the generated bubble ice cubes enter the ice storage chamber 5.

[0094] The bubbling device 16 includes a number of air tubes 161 corresponding to the number of meshes in the mesh grid. Each air tube 161 is inserted into each mesh of the mesh grid and immersed in the aqueous liquid within the mesh. The gas supply system is connected to the air tubes 161 to supply carbon dioxide gas at a predetermined pressure and volume to the bubble ice production chamber through the air tubes 161. In this example, more specifically, the bubbling device 16 also includes a horizontal straight tube 162. The bubbling device 16 is located within the bubble ice production chamber. The upper end of each air tube 161 is connected to the horizontal straight tube 162, and the lower end is inserted into each mesh of the mesh grid and immersed in the aqueous liquid within the mesh. The horizontal straight tube is connected to the gas supply system. In this example, a bubbling device is used instead of the stirring device and the compression system of Example 1. Since air is blown in each grid on the grid, the spacing between the bottoms of the grid is less than 0.5 cm. When carbon dioxide gas is injected, the gas flowing out of each air pipe can not only play a disturbing role, but also quickly generate bubble ice with the water-containing liquid. After the generation, the bottom baffle of the bubble ice generating chamber is opened, and the temperature in the bubble ice generating chamber is raised to a predetermined temperature through the circulating refrigeration system, and the bubble ice naturally falls into the ice storage chamber.

[0095] Each grid of the grid is open at the top and bottom and has a predetermined depth. A water-containing liquid is injected into the grid of the bubble ice generation chamber in a measured amount through a liquid injection system to confine the formation of bubble ice primarily within the grid, facilitating subsequent compression of the generated bubble ice by a compression system.

[0096] Preferably, the grid is made of food-grade stainless steel, such as 304 stainless steel. The grid can be composed of a plurality of rectangular grids (open at the top and bottom) of a predetermined depth. Preferably, both the aqueous liquid and the carbon dioxide gas are edible, so that the bubble ice produced by the production apparatus of the present invention can be directly used in food or beverages.

[0097] Preferably, the preparation device further comprises a visualization window 3, which is provided on the side wall of the bubble ice forming chamber 1 at a position corresponding to the grid (covering the grid), so that the formation of bubble ice solids in the grid can be observed through the visualization window.

[0098] Preferably, the preparation apparatus further comprises a monitoring device (such as a camera, not shown in the figure), which is located outside the visualization window and is used to take pictures of the bubble ice production chamber.

[0099] The gas supply system is connected to the bubble ice making chamber 1 and is used to supply carbon dioxide gas at a predetermined pressure and volume to the bubble ice making chamber 1. Preferably, the gas supply system includes a carbon dioxide cylinder 6, a gas valve 12, and a pressurizing device 7 (preferably a pressurizing pump). The carbon dioxide cylinder 6 is connected to the bubble ice making chamber 1 via the gas valve 12 and the pressurizing device 7. Preferably, the pressure of the carbon dioxide cylinder 6 when fully loaded does not exceed 6 MPa, and the volume of the carbon dioxide cylinder 6 does not exceed half of the total volume of the preparation apparatus. The gas cylinder loading area has a fixed position and a quick-release valve, allowing for quick and easy replacement of the carbon dioxide cylinder if it runs out of gas. The connection between the gas cylinder and the gas pipeline is controlled by a gas valve 12. The pressurizing device 7 is connected to the gas pipeline. If the pressure in the carbon dioxide cylinder 6 does not meet the required injection pressure, the pressurizing device 7 automatically opens to increase the gas in the gas pipeline to the required pressure and then closes, ensuring that the carbon dioxide gas is injected into the bubble ice making chamber 1 at the predetermined pressure during the bubble ice preparation process.

[0100] The liquid injection system is connected to the bubble ice making chamber and is used to supply a predetermined volume of aqueous liquid to the bubble ice making chamber. Preferably, the liquid injection system includes a liquid bottle 8, a liquid valve 14, and a liquid injection device 9 (preferably, a liquid injection pump). The liquid bottle 8 is connected to the bubble ice making chamber 1 via the liquid injection device 9 and the liquid valve 14.

Preferably, the circulating refrigeration system adopts a coil circulation refrigeration method, and the cold coil 10 in the circulating refrigeration system is attached to the surrounding walls of the bubble ice production chamber 1 and the ice storage chamber 5. Of course, the circulating refrigeration system also has the necessary compressor and fan to dissipate the heat generated by refrigeration.

[0102] The air release valve 11 is connected to the bubble ice generating chamber 1. After the bubble ice generation is completed, the excess carbon dioxide in the bubble ice generating chamber 1 is released into the ice storage chamber 5 through the air release valve 11. The released excess carbon dioxide enters the ice storage chamber to prevent the bubble ice from decomposing.

[0103] The temperature sensor (not shown) and the pressure sensor (not shown) are both connected to the bubble ice generating chamber and are used to detect the temperature and pressure in the bubble ice generating chamber.

[0104] The data acquisition and control system 13 is used to collect data from various sensors and coordinate the operation of various components. Specifically, the data acquisition and control system 13 can be connected to the bubble ice generation system, air supply system, liquid injection system, circulating refrigeration system, air release valve, compression system, temperature sensor, and pressure sensor to coordinate and control their operation. In this example, more specifically:

[0105] The data acquisition and control system collects data from temperature sensors, pressure sensors, etc., and dynamically controls the operation of other components based on the collected data.

[0106] The data acquisition and control system is respectively connected to the gas valve and the booster device in the gas supply system, and is used to control the gas supply system to inject or stop injecting carbon dioxide gas into the bubble ice forming chamber 1, and to control the bubbling rate of the bubbling device.

[0107] The data acquisition and control system is respectively connected to the liquid valve in the liquid injection system and the liquid injection device, and is used to control the liquid injection system to inject or stop injecting the water-containing liquid into the bubble ice forming chamber 1 .

[0108] The data acquisition and control system is connected to the bottom of the bubble ice generating chamber to control the opening and closing of the bottom of the bubble ice generating chamber to make the bubble ice generating chamber 1 and the ice storage chamber 5 in a closed state or a connected state.

[0109] The data acquisition and control system is connected to the air release valve to control the opening or closing of the air release valve.

[0110] The data acquisition and control system is connected to the circulating refrigeration system to control the operation of the circulating refrigeration system.

[0111] Using the above-mentioned bubble ice making device, a method for making bubble ice includes the following steps:

[0112] (1) A predetermined amount of water-containing liquid is injected into each grid of the grid in the bubble ice generating chamber through a liquid injection system according to a predetermined gas-water volume ratio (i.e., the volume ratio of carbon dioxide gas to water in the water-containing liquid), and the temperature in the bubble ice generating chamber is maintained at a first temperature (for example, the first temperature may be room temperature or may be equal to a second temperature).

[0113] (2) Turning on the gas supply system, injecting carbon dioxide gas of a predetermined pressure into the bubble ice generating chamber through the gas supply system, and controlling the bubbling rate of the bubbling device.

[0114] (3) at the second temperature, under the disturbance of the bubbling device, the water-containing liquid and the carbon dioxide gas generate bubble ice; in step (3), by dissolving saturated carbon dioxide and gaseous carbon dioxide under the disturbance of the bubbling device, the bubble ice is promoted to rapidly nucleate and generate in large quantities. The bubble ice generation method of the present invention cleverly uses the method of coupling the gas disturbance of the bubbling device with the confined space of the grid, so that the bubble ice can rely on the wall surface to quickly climb the wall and generate in the specified grid area.

[0115] (4) After the bubble ice generation is completed, the air supply system is turned off, the air vent valve is opened, and the bottom of the bubble ice generation chamber is opened so that the bubble ice generation chamber and the ice storage chamber are connected. The temperature in the bubble ice generation chamber is controlled by the circulating refrigeration system to be 2-3°C higher than the temperature at the end of the bubble ice generation, so that the bubble ice falls naturally into the ice storage chamber.

[0116] The content of bubble ice prepared by the preparation device of the present invention is 10-50 v / v, and the generation time does not exceed 15 minutes.

[0117] Preferably, the predetermined gas-liquid volume ratio in step (1) is 1:1 to 5:1. The selected gas-liquid ratio should not be too low or too high. A too low ratio will affect the final yield of bubble ice, while a too high ratio will affect the gas content in the bubble ice.

[0118] Preferably, the first temperature is 0-20°C;

[0119] Preferably, the predetermined pressure in step (2) is not higher than 4 MPa.

[0120] Preferably, the bubbling rate of the bubbling device is 2 ml / min to 20 ml / min.

[0121] Preferably, the second temperature in step (3) is 0-5°C.

[0122] Preferably, in step (3), the formation of bubble ice is determined by at least one of visual observation, pressure drop (pressure drop rate greater than 0.2 MPa / min) and temperature fluctuation (temperature fluctuation greater than 1°C). If the formation is slow or the amount of formation is small (preferably, if the amount of bubble ice generated within 10 minutes is less than 10 v / v, it is considered that the formation is slow or the amount of formation is small), the bubbling rate of the bubbling device is increased and / or the temperature is lowered to accelerate the formation of bubble ice.

[0123] Preferably, in step (4), when the pressure drop rate in the bubble ice generating chamber is less than 0.01 MPa / h, or when the amount of bubble ice generated is ≥10 v / v, it is considered that the bubble ice generation is completed.

[0124] Preferably, steps (1) to (4) are repeated to continuously generate bubble ice.

[0125] In the present invention, the aqueous liquid can be edible, for example, pure water, or water with other edible additives (such as sugars, amino acids, various beverages, beer, etc.). Edible liquids (such as various beverages, beer, etc.) can also be directly used as the medium for generating bubble ice, as long as the gas-water volume ratio meets the predetermined requirements during the preparation of the bubble ice.

[0126] In the present invention, the carbon dioxide gas can be edible, and its purity is ≥99.99%. The carbon dioxide must be in a gaseous state, and its temperature and pressure conditions are relatively harsh and must be lower than the liquefied and supercritical conditions. The temperature in the carbon dioxide cylinder 6 is not higher than 293K, and the maximum pressure is not higher than 4MPa.

[0127] Example 3

[0128] Using the bubble ice making device of Example 1 or 2, a method for making bubble ice includes the following steps:

[0129] (1) A predetermined amount of edible aqueous liquid is injected into the bubble ice generating chamber through a liquid injection system at a gas-water volume ratio of 3:1, and the temperature in the bubble ice generating chamber is maintained at room temperature; in this example, the edible aqueous liquid is purified water.

[0130] (2) If the bubble ice preparation device of Example 1 is used, the stirring device is turned on and the speed is set to 500 r / min. According to the carbon dioxide phase equilibrium line, edible grade carbon dioxide gas at a predetermined pressure (not higher than 4 MPa) is injected into the bubble ice generation chamber through the gas supply system, so that the carbon dioxide quickly dissolves in the water. After the carbon dioxide dissolves in the water at equilibrium (the pressure in the bubble ice generation chamber is monitored by the data acquisition and control system. When the pressure in the bubble ice generation chamber is at a constant pressure within the range of 1-3 MPa and the pressure drop is less than 0.01 MPa, it is considered that the dissolution equilibrium is reached), the gas supply system is turned off. In this case, the edible grade carbon dioxide gas is injected into the bubble ice generation chamber and dissolved for 2 minutes to reach the dissolution equilibrium.

[0131] If the bubble ice making device of Example 2 is used, the gas supply system is directly turned on, and food-grade carbon dioxide gas at a predetermined pressure (not higher than 4 MPa) is injected into the bubble ice making chamber through the gas supply system. The bubbling rate of the bubbling device is controlled to 10 ml / min, and the bubbling is continued until the bubble ice is completely formed, and then the gas supply system is turned off.

[0132] (3) Under dynamic conditions, the temperature in the bubble ice generation chamber is lowered to 5°C (cooling rate ≥ 2K / min) by a circulating refrigeration system. Under the stirring of the stirring device or the disturbance of the bubbling device, the water-containing liquid and the carbon dioxide gas generate bubble ice. In this example, the temperature in the bubble ice generation chamber is lowered to the target temperature within 5 minutes. The dynamic conditions refer to: during the process of bubble ice generation, the formation of bubble ice is determined by at least one of visual observation, pressure drop (pressure drop rate greater than 0.2MPa / min) and temperature fluctuation (temperature fluctuation greater than 1°C). If the generation is slow or the amount of bubble ice generated is small (preferably, if the amount of bubble ice generated within 10 minutes is less than 10 v / v, it is considered that the generation is slow or the amount of bubble ice generated is small), the rotation speed of the stirring device is increased (such as increasing the rotation speed to 800r / min, 1000r / min, etc., higher than the original setting of 500r / min), the bubbling rate of the bubbling device is increased, and / or the temperature is lowered (such as lowering the temperature to 0°C) to accelerate the generation of bubble ice.

[0133] (4) After the bubble ice generation is completed (when the pressure drop rate in the bubble ice generation chamber is less than 0.01 MPa / h, or when the amount of bubble ice generated is ≥10 v / v, the bubble ice generation is considered to be completed), open the air release valve to release the unreacted carbon dioxide into the ice storage chamber to protect the bubble ice:

[0134] When the bubble ice making device of Example 1 is used, since the bottom end of the compression push rod 42 is flexible and has a shape matching the mesh grid 2, the bubble ice in the mesh grid is compressed into smaller bubble ice through the compression push rod 42 in the compression system, and at the same time, the bottom of the bubble ice generating chamber is opened to connect the mesh grid with the ice storage chamber so that the bubble ice enters the ice storage chamber.

[0135] When the bubble ice preparation device of Example 2 is used, the temperature in the bubble ice generation chamber is controlled by the circulating refrigeration system to be 2-3°C higher than the temperature at the end of the bubble ice generation. For example, if the temperature in the bubble ice generation chamber is 5°C at the end of the bubble ice reaction, the temperature in the bubble ice generation chamber is controlled to 7-8°C by the circulating refrigeration system, so that the bubble ice naturally falls off into the ice storage chamber.

[0136] (5) Steps (1) to (4) can be repeated to continuously generate bubble ice (during the continuous generation process, the temperature in step (1) can be maintained at the temperature of the bubble ice generation chamber when the bubble ice last entered the ice storage chamber).

[0137] The actual bubble ice (edible) prepared in Example 3 is as follows Figure 5 As shown in the scanning electron microscope (SEM) images of bubble ice at different magnifications, Figure 6-Figure 7 As shown, carbon dioxide hydrate crystals are clearly visible in the figure. Figure 8 This is a Raman comparison of the bubble ice produced in Example 3 and ordinary ice (made from pure water). The bubble ice produced in Example 3 has a distinct peak for carbon dioxide hydrate. When the bubble ice is placed in water, the hydrogen bonds within the carbon dioxide hydrate break, allowing the carbon dioxide molecules within the hydrate cages to diffuse out, forming bubble ice water. This achieves both refrigeration and bubble generation.

[0138] Example 4

[0139] The difference from Example 3 is that the edible aqueous liquid is apple flavored soda drink + water, and the resulting bubble ice can be named apple flavored bubble ice, such as Figure 9 and Figure 10 shown.

[0140] Example 5

[0141] The difference from Example 3 is that the edible aqueous liquid is cola + water, and the resulting bubble ice can be named cola bubble ice, such as Figure 11 shown.

[0142] Example 6

[0143] The difference from Example 3 is that the edible aqueous liquid is beer+water.

[0144] like Figure 12 The figure shows the generation amount of different types of bubble ice in Examples 3-6. It can be seen that under the preparation device and method of the present invention, the generation amount of bubble ice can exceed 10v / v within 5 minutes.

[0145] Example 7

[0146] The difference from Example 3 is that the aqueous liquid is essential oil (or perfume) + water.

[0147] The present invention provides a brand-new choice for places and people who need cold drinks and refreshing foods. The prepared product, bubble ice (carbon dioxide hydrate), is innovative, interesting and convenient. Compared with traditional carbonated beverages, it has the properties of a cold drink and can be directly added to ordinary beverages or wine to replace the effect of refrigerated bubble water. Compared with traditional refreshing foods, bubble ice can be eaten directly or can be directly made into products with a bubble taste (such as bubble ice cream), which can give consumers more choices. The bubble ice of the present invention can fill the gap in beverages and refreshing foods, and can effectively solve the problems of existing beverages without bubbles and bubble drinks with insufficient bubbles, bringing innovation to the food industry.

[0148] Application scenarios of the present invention may include:

[0149] 1. By preparing bubble ice and adding it directly to pure water, regular beverages and alcoholic beverages, a dual improvement of existing beverages can be achieved. It can not only lower the temperature of the beverage but also increase the bubble content of the beverage, enriching the taste of the beverage. Especially in summer, people need a lot of cold drinks, or drinks with bubbles that stimulate the taste. The addition of bubble ice can meet the requirements of consumers.

[0150] 2. By adding sugars and other additives (such as cola, apple-flavored soda, and beer), bubbly ice products with varying tastes can be created. In high-temperature regions (average annual temperature > 25°C), convenience store cold chain systems can enhance product premiums through differentiated bubble textures. For example, in summer, the market for refreshing foods (such as ice cream) is huge. To address the severe homogeneity of cold drink products in high-temperature environments, bubbly ice cream can be created, allowing consumers to experience the original dessert-like texture of ice cream with the added layer of bubbly. The slight vibration frequency (50-100Hz) generated by the bursting bubbles aligns with the tactile sensitivity range of the tongue, enhancing pleasure. The microbubbles absorb heat during phase transition, accelerating the instantaneous cooling rate upon ingestion, significantly enhancing the duration of the refreshing sensation and enriching the existing ice cream product offerings.

[0151] 3. Bubble ice with health functions and active factors can be prepared by adding appropriate amounts of amino acids (such as leucine, methionine, tryptophan, etc.) or vitamins (such as vitamin A, vitamin B, vitamin C and vitamin D, etc.). Adding amino acids or vitamins can not only prepare bubble ice with health functions but also accelerate the kinetics of bubble ice formation, killing two birds with one stone and significantly accelerating the ice making efficiency and bubble ice formation content.

[0152] 4. To address the problem of insufficient bubbles and lack of cooling sensation after a second consumption of a bubble drink, the bubble ice of the present invention can quickly and continuously replenish bubbles and quickly reduce the temperature. In the hot summer season, people usually like to drink cold drinks (such as cola, apple-flavored soda, beer, etc.), and as the flavors of drinks diversify, people begin to gradually pursue the unique taste brought by drinks. Bubble drinks such as sparkling water and carbonated drinks themselves have a bubbly taste, but because the gas in the liquid is unstable and easily escapes into the gas phase, bubble drinks generally have no bubble taste after a second use or when left for a long time, and the taste of cold drinks becomes worse when the temperature rises. There is currently no solution to this problem, and adding bubble ice will solve the above two problems at the same time. While quickly replenishing bubbles, the decomposition of bubble ice has the property of absorbing heat, which will quickly lower the liquid temperature so that the drink has bubbles and a cold drink taste again, thereby improving the drinkability of the original drink. This is especially true for large-bottle canned bubble drinks, as it can reduce the waste of drinks and increase the value of the drinks.

[0153] 5. For special settings requiring visual effects and scented atmospheres, we propose a method that uses bubble ice to lock in essential oils, which then melts to release fragrance. In ceremonial or romantic settings (such as the seaside), this oil-locked bubble ice can be used as a decorative element, scent enhancer, and visual sensory element. Upon melting, it releases mist and fragrance, creating a unique and romantic atmosphere. The type of locked essential oil can be selected based on scent. This enriches the range of existing perfumes and the display of scented accessories, enhancing the quality and value of perfumes or fragrances through a unique visual experience.
