Description

Technical Field

[0001] The utility model relates to the technical field of tagatose crystallization, in particular to a tagatose crystallization device. Background Art

[0002] A tagatose crystallization device is specially designed for producing tagatose. Its main purpose is to improve production efficiency and product quality through efficient evaporation and crystallization process. Air-cooled crystallization: using cooling medium (such as air or water) to cool the solution so that the solute precipitates crystals in a supersaturated state. Air-cooled crystallization has the advantages of simple equipment and convenient operation, but it is necessary to pay attention to controlling the cooling speed and temperature distribution uniformity;

[0003] After searching, the utility model with the announcement number CN215462137U discloses a crystallization device for tagatose. Although the utility model patent solves the problem that the liquid concentration is first increased by evaporation and then cooled for crystallization in the prior art, it is necessary to first cool down the heated tank body and then perform the cooling process. When crystallizing again, it is necessary to heat up again, which consumes a lot of energy, slows the crystallization process, and cannot be continuously produced; however, the utility model patent has the following problems:

[0004] First, excessive stirring during the crystallization process can easily cause too many small particles to be produced during the crystallization process, affecting the quality of tagatose crystals. This utility model patent uses a second motor to drive a stirring blade to stir tagatose, promoting uniform contact between tagatose and cold air, allowing tagatose to crystallize quickly, making it difficult to control the quality of tagatose crystals;

[0005] Second, the utility model patent requires that the tagatose crystals in the crystallization tank be completely precipitated before the next batch of tagatose crystals can be precipitated. The continuity of the processing is low and the crystallization efficiency is low;

[0006] 3. When the temperature is lowered, tagatose crystals in the tagatose solution are precipitated, and a saturated mother liquor is produced at the same time. The utility model patent needs to perform filtering and drying again to obtain tagatose crystals, which is a relatively troublesome process.

[0007] Therefore, a tagatose crystallization device is proposed. Utility Model Content

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

One end of the connecting rod 18 is hinged with a connecting rod 29, and one end of the connecting rod 29 is hinged with a hinged rod 10. The end of the hinged rod 10 away from the connecting rod 29 is hinged with a connecting block 11. The bottom of the connecting block 11 is fixedly connected with a limiting rod 12, and an arc groove 13 is provided on one side of the limiting rod 12. The limiting rod 14 is slidably connected inside the limiting rod 12, and the limiting rod 14 is fixedly connected to the inner wall of the crystallization box 1.

[0029] The top of the crystallization box 1 is connected with a feed pipe 15, the outer wall of the crystallization box 1 is connected with an air conditioner, the exhaust hole of the air conditioner is connected with the crystallization box 1, a discharge port 18 is provided on one side of the crystallization box 1, a filter plate 19 is fixedly connected inside the discharge port 18, the filter plate 19 is fixedly connected with a group of scrapers 5 located below, and a drain port 20 is connected at the bottom of the crystallization box 1. A fan 21 is fixedly connected to the inner wall of the crystallization box 1, and the fan 21 is located above the filter plate 19. The fan 21 dries the crystals of tagatose precipitated on the upper surface of the filter plate 19, and further cools down, thereby improving the crystallization efficiency of tagatose. The exhaust port of the air conditioner is connected with an exhaust duct 17, and two groups of exhaust ducts 17 are provided, and the two groups of exhaust ducts 17 are respectively located on one side of the two groups of transmission rollers 4. A baffle 23 is slidably connected to the outer wall of a group of transmission rollers 4 located above, and the baffle 23 is against the outer wall of the transmission roller 4. The baffle 23 prevents the concentrated tagatose solution entering the crystallization box 1 from the feed pipe 15 from flowing out. A base 22 is fixedly connected to the bottom of the crystallization box 1, and the motor 1 2, the motor 2 7, the air cooler and the fan 21 are electrically connected to the external power supply. The air cooler and the fan 21 are prior arts well known to those skilled in the art, so they are not described in detail.

[0030] When the utility model is working: the motor 1 2 is started, the motor 1 2 drives the pulley 3 and the driving roller 4 to rotate, and the upper driving roller 4 rotates with the cooperation of the driving belt 6, the air conditioner is started, and the air conditioner discharges the generated cold air to the two groups of driving rollers 4 through the two exhaust pipes 17, so that the temperature of the driving rollers 4 is reduced, and the tagatose liquid that meets the requirements of tagatose crystallization is slowly poured into the crystallization box 1 through the feeding pipe 15, and the tagatose liquid falls on the surface of the upper driving roller 4, and the motor 2 7 is started, the motor 2 7 drives the connecting rod 1 8 to rotate, the connecting rod 1 8 drives the connecting rod 2 9 and the hinged rod 10 to move, and the hinged rod 10 drives the connecting block 11 and the limiting rod 12 to move.

The tagatose liquid falling on the surface of the upper transmission roller 4 is spread out by linear motion, and the cold air discharged from the exhaust duct 17 preliminarily cools the spread tagatose liquid and precipitates a small part of tagatose crystals. During the rotation of the upper transmission roller 4, the upper scraper 5 scrapes off the cooled tagatose liquid and crystals, and the scraped tagatose liquid and crystals fall on the surface of the lower transmission roller 4. During the rotation of the lower transmission roller 4, the tagatose liquid is driven to cool down for a second time, so that all crystals are precipitated. The precipitated crystals are scraped off by the scraper 5 below, and the fan 21 is started. The fan 21 directly blows air to the crystals to dry them, and then they are discharged from the discharge port 18 along the filter plate 19. At the same time, the mother liquor generated is filtered by the filter plate 19 and discharged from the discharge port 20. The processed tagatose is directly dried and filtered, and no secondary processing is required, which has high efficiency. Tagatose is less stirred during the crystallization process, so that fewer small particles are produced during the crystallization process, thereby improving the quality of tagatose crystals; at the same time, tagatose crystals can be precipitated continuously with high efficiency, and the secondary cooling makes the tagatose crystal precipitation rate high.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
