DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0026] Embodiment one: please refer to Figure 1 - Figure 6The utility model provides following technical scheme: a drying machine for trichloro sucrose production, including shell 1, both sides of shell 1 inside are fixedly connected with side plate 3, and shell 1 opposite side plate 3 top and both sides form the package structure, and one side of shell 1 is equipped with exhaust window 2, be equipped with drying structure between two exhaust windows 2, and drying structure includes four transmission rollers 4 rotationally connected between two exhaust windows 2, and four transmission rollers 4 outside rotationally connected with conveyer belt 5, conveyer belt 5 forms trapezoidal structure, and conveyer belt 5 top is provided as inclined plane, and exhaust window 2 is located in conveyer belt 5 top lower end, simultaneously, transmission roller 4 is driven by motor, shell 1 bottom is equipped with the collection structure of collecting material, two exhaust windows 2 inside top fixedly connected with heating fin 6, and heating fin 6 is equidistantly distributed between two exhaust windows 2, and heating fin 6 inside fixedly connected with electric heating wire 7 of S shape structure distribution, heating fin 6 and conveyer belt 5 top inclined plane are in parallel distribution, and heating fin 6 top is equipped with three equidistantly distributed suction fans 8, and suction fan 8 is fixedly connected with shell 1, conveyer belt 5 top inclined plane higher end is equipped with liquid supply pipe 9, and both ends of liquid supply pipe 9 are fixedly connected with the outside of side plate 3 through support, and liquid supply pipe 9 extends to shell 1 inside, liquid supply pipe 9 bottom fixedly connected with equidistantly distributed spray head 10, and liquid supply pipe 9 is connected with solution supply equipment through pipeline, spray head 10 and conveyer belt 5 top inclined plane are vertically distributed, and be equipped with isolation plate 11 between spray head 10 and heating fin 6.

[0027] First, through pipeline, trichloro sucrose solution supply equipment and liquid supply pipe 9 are connected with each other, and then the trichloro sucrose solution is uniformly sprayed on the outside of the conveyer belt 5 through the multiple spray heads 10 at the bottom of the liquid supply pipe 9, so that the trichloro sucrose solution forms a uniform film on the outside of the conveyer belt 5. At this time, the transmission roller 4 is driven to rotate by the motor, and then the conveyer belt 5 is driven to rotate on its outside by the rotation of the transmission roller 4. At this time, the conveyer belt 5 will drive the trichloro sucrose solution on its outside to move towards the direction of the exhaust window 2.

[0028] During the movement of the trichloro sucrose solution, the electric heating wire 7 is powered to heat, and then the heating fin 6 is heated. The heat of the electric heating wire 7 is uniformly projected on the trichloro sucrose solution through the heating fin 6, and the trichloro sucrose solution is heated, and then the moisture in the trichloro sucrose solution is evaporated. At the same time, the suction fan 8 is started to suck the external gas into the inside of the shell 1. At this time, the external air will pass through the multiple heating fins 6 inside, and then the external gas is heated. At the same time, the high-temperature gas after heating will evaporate the moisture in the trichloro sucrose solution. After the gas enters the inside of the shell 1 through the suction fan 8, it will be discharged from the inside of the shell 1 through the exhaust window 2. In the process of gas flow, the water vapor in the inside of the shell 1 is taken away, so as to complete the drying treatment of the trichloro sucrose solution.

[0029] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] When the sucralose solution is dried, sucralose crystals will be formed, at this time, the sucralose crystals will be attached to the outer side of the conveying belt 5, when the sucralose crystals move with the conveying belt 5 to the bottom of the conveying belt 5, at this time, the rotating block 15 is driven to rotate by the motor, and the two vibration rollers 16 are driven to rotate around them by the rotating block 15. The vibration roller 16 will periodically impact the conveying belt 5. Since the conveying belt 5 is elastic, the bottom of the conveying belt 5 will vibrate with the impact of the vibration roller 16, and the sucralose crystals on the bottom of the conveying belt 5 will fall off due to the vibration of the conveying belt 5. At this time, the base 12 and the drawer 13 at the bottom of the conveying belt 5 will collect the sucralose crystals. The collected sucralose crystals will fall on the top of the drawer 13, at this time, the drawer 13 can be pulled out from the inside of the base 12 to concentrate the sucralose crystals.

[0031] When the sucralose crystals on the bottom of the conveying belt 5 are not completely removed, the outer side of the conveying belt 5 will pass through the scraper 14 at this time. Since the scraper 14 is wedge-shaped and the scraper 14 and the conveying belt 5 are in close contact, the scraper 14 will scrape the outer side of the conveying belt 5, thereby separating the residual sucralose crystals on the outer side of the conveying belt 5 from the conveying belt 5.

[0032] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for part of the technical features, any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
