Description

Technical Field

[0002] Menthol is an organic substance with the chemical properties of colorless needle-shaped crystals and a refreshing mint aroma. It is soluble in organic solvents such as ethanol, acetone, ether, chloroform and benzene, and slightly soluble in water. It is chemically stable and can evaporate with steam. Menthol is produced in the leaves and is the main component of peppermint oil. The freeze-out method is a method based on the difference in freezing points between different components in the mint flavor mixture. It solidifies and precipitates high-melting-point substances by cooling them down and separates them from other liquid components.

[0003] During freeze-out, the menthol crystallization needs to be left to stand for a period of time so that the impurities and water in the solution can be precipitated, and the upper clear liquid is taken for freeze-out, which is a relatively troublesome operation and requires a new carrying space; and the temperature inside the space is lowered by a freeze-out crystallization device so that the placed menthol solution can be cooled and freeze-out, but the refrigerant action position and action area inside the freeze-out device are fixed, so that the temperature inside the freeze-out space is prone to form a step difference, and the temperature of different areas of the static menthol solution is different, which requires different cooling time and efficiency in different areas when the menthol solution is freeze-out crystallized, and it is necessary to wait for the menthol solution in the area with slow cooling rate to freeze-out crystallize before completing this step, so that the required freeze-out crystallization time is longer, resulting in low freeze-out crystallization efficiency.

The inner wall of the protective outer shell 1 is rotatably connected to two driving shafts 3 for driving the storage barrel 2. The two driving shafts 3 are fixedly connected to the bottom ends of the corresponding storage barrels 2, and the bottom ends of the two driving shafts 3 are fixedly connected to transmission shafts 31. A synchronously rotating transmission belt 32 is arranged between the two transmission shafts 31, and the two transmission shafts 31 are rotatably connected through the synchronously rotating transmission belt 32.

[0020] In this embodiment, the protective outer shell 1 supports and protects the components of the device from the outside. The protective outer shell 1 forms a connected cavity through two inner grooves 12. The blocking top cover 13 blocks the top of the internal cavity of the protective outer shell 1 to prevent the external air from exchanging with the internal air of the protective outer shell 1 when the device is in use. The size of the top feed port 121 corresponds to the inner diameter of the storage barrel 2. The storage barrel 2 carries the menthol solution. The menthol solution is put into the storage barrel 2 through the top feed port 121. The storage barrel 2 supports the telescopic machine 21, and the telescopic machine 21 separates the partition 2. 2 is supported and driven. When the separation partition 22 is opened, the menthol solution stored in the storage barrel 2 can flow in series. After the menthol solution in the storage barrel 2 is left to stand and stratify, the separation partition 22 is closed to achieve sealing of the separation partition 22 to separate the internal space of the storage barrel 2, so that the menthol solution above the separation partition 22 is the clear liquid, and the impurities and water below the separation partition 22 are, and the menthol solution can be frozen out without taking out the clear liquid separately. The inner tank 12 gives way to the storage barrel 2. The storage barrel 2 is designed to rotate inside the inner tank 12. The protective outer shell 1 is provided with For the driving element driven by one of the transmission shafts 31, when the transmission shaft 31 rotates, the other transmission shaft 31 is driven to rotate through the synchronously rotating transmission belt 32, so that the two transmission shafts 31 can realize synchronous rotation, and the two transmission shafts 31 drive the two storage barrels 2 to realize synchronous rotation. When the storage barrel 2 rotates, the menthol solution clear liquid inside is driven to rotate, and the cooling machine 11 is controlled to output cold air. The cold air output by the cooling machine 11 acts on the two storage barrels 2. The storage barrel 2 is made of a material with good thermal conductivity. The storage barrel 2 transfers the cold air temperature to the menthol solution inside, so that the menthol solution The menthol solution is driven to rotate by the two storage barrels 2 so that different angular positions of the storage barrel 2 can correspond to the cooler 11 alternately, so that the areas at different angular positions of the storage barrel 2 can evenly receive the cold air output by the cooler 11, thereby increasing the temperature uniformity at different positions of the storage barrel 2, and thus enabling the menthol solution in the ear canal of the storage barrel 2 to achieve a more uniform and stable cooling treatment, so that the difference in cooling time and efficiency in different areas when the menthol solution is freeze-thawed and crystallized is reduced, thereby reducing the required freeze-thaw crystallization time and improving the freeze-thaw crystallization work efficiency.

[0022] A plurality of airflow guide plates 14 for guiding the airflow output by the cooler 11 are fixedly connected to the inner walls of the two inner grooves 12. The plurality of airflow guide plates 14 are evenly distributed, and the plurality of airflow guide plates 14 are used to prevent contact with the storage barrel 2. The cross-sections of the plurality of airflow guide plates 14 are all triangular. When the cold airflow output by the cooler 11 diffuses and flows into the inner groove 12, the cold airflow is affected by the airflow guide plates 14 and changes direction, thereby increasing the effect of the cold airflow on the storage barrel 2, thereby improving the efficiency of the storage barrel 2 in driving the menthol solution to cool down, and the airflow guide plates 14 will not interfere with the rotation of the storage barrel 2.

[0023] An inner cavity 221 is provided in the separation baffle 22, and a plurality of liquid flow holes 23 are provided on the separation baffle 22. The inner cavity 221 is connected with the inner space of the storage barrel 2 through the plurality of liquid flow holes 23. The storage barrel 2 realizes the ability of the upper and lower liquids of the separation baffle 22 to intersect and flow through the plurality of liquid flow holes 23. The solution passes through the liquid flow holes 23 into the inner cavity 221, and then the solution is discharged through the inner cavity 221, thereby realizing the static stratification of the solution inside the storage barrel 2.

[0024] The inner wall of the inner cavity 221 is rotatably connected to a rotating disk 24, and a plurality of rotating sealing plates 241 for sealing the liquid flow holes 23 are fixedly connected to the side walls of the rotating disk 24, and the rotating sealing plates 241 are rotatably connected to the inner wall of the inner cavity 221; the rotating sealing plates 241 are used to seal the separation baffle 22, and the rotating disk 24 supports and drives the plurality of rotating sealing plates 241. The inner wall of the telescopic machine 21 is provided with a driving element for acting on the rotating disk 24, so that the rotating disk 24 can drive the rotating sealing plates 241 to rotate. When the solution is allowed to stand and stratify, the rotating disk 24 is controlled to drive the plurality of rotating sealing plates 241 to rotate to seal the plurality of liquid flow holes 23, so that the separation baffle 22 can separate the upper and lower layers of solution inside the storage barrel 2 to prevent impurities and moisture from flowing upward.

[0026] The working principle and use process of the utility model are as follows: when the menthol solution is subjected to freeze-out crystallization treatment, the blocking top cover 13 is controlled to slide upward and separate from the protective outer shell 1, and then the menthol solution is put into the storage barrel 2, and then the blocking top cover 13 is closed. After the stratification of the solution inside the storage barrel 2 is completed, the two rotating disks 24 are controlled to rotate, and the rotating disks 24 drive the corresponding rotating blocking plates 241 to rotate, and the rotating blocking plates 241 rotate to block the liquid flow holes 23, so that the separation partition 22 can separate the upper and lower layer solutions inside the storage barrel 2 to prevent impurities and moisture from flowing upward, and the menthol solution clear liquid can be frozen out without taking out the menthol solution separately, and then the cooling machine 11 is controlled to output cold air, and the cold air output by the cooling machine 11 acts on the two storage barrels 2, and the storage barrel 2 transmits the cold air temperature to the menthol solution inside, so that the menthol solution can be frozen out. The alcohol solution is cooled and frozen, and then the transmission shaft 31 is controlled to rotate. When the transmission shaft 31 rotates, the synchronously rotating transmission belt 32 drives another transmission shaft 31 to rotate, so that the two transmission shafts 31 can achieve synchronous rotation, and the two transmission shafts 31 drive the two storage barrels 2 to achieve synchronous rotation. When the storage barrel 2 rotates, the menthol solution clear liquid inside is driven to rotate, so that different angular positions of the storage barrel 2 can alternately correspond to the cooling machine 11, so that the areas at different angular positions of the storage barrel 2 can evenly receive the cold air output by the cooling machine 11, thereby increasing the temperature uniformity of different positions of the storage barrel 2, and thereby enabling the ear canal menthol solution in the storage barrel 2 to achieve more uniform and stable cooling treatment, so that the difference in cooling time and efficiency in different areas when the thin alcohol solution is frozen and crystallized is reduced, thereby reducing the required freezing and crystallization time and improving the working efficiency of freezing and crystallization.
