Description

Technical Field

[0001] This utility model relates to the field of trehalose production, and in particular to a decolorization device for decolorizing trehalose solution. Background Technology

[0002] Trehalose is a natural disaccharide composed of two glucose molecules linked by an α-1,1 glycosidic bond. It is widely found in some fungi, bacteria, plants, and seaweed. Various technologies can be used to decolorize trehalose solutions. The specific equipment selection depends on the source of the trehalose solution, the degree of color, the decolorization effect requirements, and the production scale.

[0003] A search revealed Chinese Patent Publication No. CN216604954U, which discloses an activated carbon mixing device for decolorizing sugar solution. The device includes: a mixing chamber; a drive shaft rotatably mounted at the center of the mixing chamber, with one end extending outside the mixing chamber and fixedly connected to a drive motor for rotating it; several partition plates fixed to the drive shaft and evenly distributed around its circumference; a stirring mechanism positioned between two adjacent partition plates for stirring the sugar solution; an activated carbon assembly mounted on the stirring mechanism for decolorizing the sugar solution; an inlet pipe connected to the upper part of the mixing chamber; and an outlet pipe connected to the lower part of the mixing chamber. This allows the entire sugar solution decolorization process to proceed continuously without stopping the sugar solution delivery from the inlet pipe. The device features a clever and simple structure with a high degree of automation.

[0004] The aforementioned device, although it divides the space within the mixing chamber by setting partitions to allow the entire sugar solution decolorization process to proceed continuously without stopping the sugar solution delivery from the inlet pipe, generally requires tens of minutes for activated carbon decolorization. This device, however, has a short overall decolorization time because the sugar solution enters through the inlet pipe and is discharged once the partition moves to the desired location. Furthermore, its stirring mechanism lacks a drive motor and relies on the interaction of cylindrical spur gears and internal gears for rotation. The stirring rate depends on the moving speed of the partition plate, while the sugar solution does not remain in the mixing chamber for long. This leads to the risk of uneven mixing between the activated carbon and the sugar solution, affecting the decolorization effect and making the device impractical. Therefore, a decolorization device for seaweed sugar solution decolorization is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a decolorization device for decolorizing trehalose solution. It aims to improve upon the existing technology where the trehalose solution enters through the inlet pipe and is discharged once the partition moves to the desired position. This results in a short overall decolorization time. Furthermore, the stirring mechanism does not have a drive motor but is rotated by the combination of cylindrical spur gears and internal gears. The stirring rate depends on the moving speed of the partition plate, and the trehalose solution does not stay in the mixing tank for long. This leads to the risk of uneven mixing of activated carbon and trehalose solution, affecting the decolorization effect.

[0033] like Figure 3 - Figure 4 The drive assembly 31 includes a primary motor 311, which provides power to the assembly. The primary motor 311 is fixedly connected to the decolorizing tank 1. The output end of the primary motor 311 is fixedly connected to a rotating shaft 312, which is used to connect with the connecting shell 313. The rotating shaft 312 passes through the decolorizing tank 1 and is rotatably connected to the decolorizing tank 1. The lower part of the rotating shaft 312 is fixedly connected to the connecting shell 313, which is used to connect the various components. The connecting shell 313 is rotatably connected to the top of the inner wall of the decolorizing tank 1. A gear ring 314 is provided inside the connecting shell 313. The gear ring 314 is fixedly connected to the top of the inner wall of the decolorizing tank 1 and is used to drive the gear 322 to rotate. An auxiliary cylinder 315 is fixedly connected to the lower left side of the connecting shell 313, which is used to connect with the stirring assembly 32.

[0034] Furthermore, the stirring assembly 32 includes a stirring rod 321 for connecting to the stirring plate 323. The stirring rod 321 passes through the auxiliary cylinder 315 and is rotatably connected to the auxiliary cylinder 315. A gear 322 is fixedly connected to the top of the stirring rod 321 for engaging with the gear ring 314 to drive the stirring rod 321 to rotate. The gear 322 meshes with the gear ring 314. Multiple stirring plates 323 are fixedly connected to the outer wall of the stirring rod 321 for stirring the mixture.

[0035] Please see Figure 2 and Figure 5 The filtration mechanism 2 includes a housing 21 for connecting various components. A connecting pipe 13 passes through the housing 21 and is fixedly connected thereto. A filter cylinder 22 is fixedly connected inside the housing 21 for separating sugar solution and activated carbon. The connecting pipe 13 passes through the filter cylinder 22 and is fixedly connected thereto. A filter element 23 is provided in the middle of the filter cylinder 22 for conveying materials and assisting in the separation of sugar solution and activated carbon. It can convey the filtered activated carbon to the discharge pipe 212. A liquid outlet pipe 211 is fixedly connected to the left side of the bottom surface of the housing 21 for discharging the decolorized and filtered sugar solution. A discharge pipe 212 is fixedly connected to the right side of the bottom surface of the housing 21 for discharging the used activated carbon. A slope 213 is provided at the lower part of the inner wall of the housing 21 for guiding the sugar solution to the liquid outlet pipe 211.

[0036] Furthermore, the filter element 23 includes a second motor 231 for providing power to the component. The second motor 231 is fixedly connected to the housing 21.

[0037] Working principle: In use, the syrup to be decolorized is fed into the decolorization tank 1 through the inlet pipe 11, and then activated carbon is fed into the decolorization tank 1 through the feed pipe 12. Then, the first motor 311 is turned on, which drives the rotating shaft 312 to rotate. The connecting shell 313, which is fixed to the rotating shaft 312, will also be driven to rotate. When the connecting shell 313 rotates, it will drive the lower auxiliary cylinder 315 to move together. The stirring rod 321 connected to the auxiliary cylinder 315 will move accordingly, and the gear 322 will rotate around the gear ring 314. The gear 322 meshing with the gear ring 314 will also rotate, and the gear 322 will drive the stirring rod 321 fixed to it to rotate. The stirring rod 321 will then rotate. Plate 323 mixes the sugar solution and activated carbon in the decolorization tank 1, thereby enabling the activated carbon to assist in the decolorization of the trehalose solution. After the trehalose solution is decolorized, it can be sent into the filtration mechanism 2 through the connecting pipe 13. The mixture of sugar solution and activated carbon will fall into the filter cylinder 22, which will filter out the sugar solution and leave the activated carbon inside. The second motor 231 is turned on, which will drive the connecting shaft 232 to rotate. When the connecting shaft 232 rotates, the spiral blade 233 fixed to it will rotate accordingly, thereby conveying the activated carbon in the filter cylinder 22 towards the discharge pipe 212 until the activated carbon is discharged through the discharge pipe 212. At the same time, the sugar solution filtered out by the filter cylinder 22 will be sent out through the liquid outlet pipe 211.
