Description

Technical Field

[0001] This utility model relates to the field of fructose production technology, and in particular to a crystallization tank for fructose production. Background Technology

[0002] As an important natural sweetener, fructose crystallization is a crucial step in its industrial production, determining the purity and particle uniformity of the product. Traditional fructose crystallization processes often employ jacketed crystallizers, where cooling water or a heating medium is circulated through an external jacket to control the temperature of the solution inside the tank and induce crystallization.

[0003] However, most existing crystallizers use a single jacket structure, with cooling water entering from the bottom and flowing out from the top, forming a unidirectional flow. While this design can achieve basic cooling, the cooling water is unevenly distributed within the jacket, and the heat transfer efficiency varies significantly at different heights of the tank wall, making it difficult to meet the high requirements for temperature uniformity in fructose crystallization.

[0004] Therefore, this application provides a crystallization tank for fructose production to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a crystallization tank for fructose production, which solves the problem that existing crystallization tanks mostly adopt a single jacket structure, with cooling water entering from the bottom of the jacket and flowing out from the top, forming a unidirectional flow that leads to uneven distribution of cooling water in the jacket, differences in heat transfer efficiency in different height areas of the tank wall, and difficulty in meeting the high requirements of temperature uniformity for fructose crystallization.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A crystallization tank for fructose production includes a tank body. Two parallel vertical water distribution tanks are fixed on one side of the tank body. Connecting pipes are fixed to the outer sides of the two water distribution tanks. Multiple water distribution pipes for extending into the interlayer of the tank body are fixed to the inner side of each water distribution tank. The internal interlayer of the tank body is divided into multiple cooling chambers from top to bottom. The multiple cooling chambers are respectively connected to the water distribution pipes at corresponding positions.

[0008] The top of the tank has an annular connecting cavity, which is connected to the cooling cavity located at the top. A motor is fixed to the top of the tank, and the motor shaft extends into the tank and is fixed with a vertical stirring shaft. A U-shaped stirring tube adapted to the inner cavity of the tank is fixed to the bottom of the stirring shaft, and the top of the U-shaped stirring tube is connected to the connecting cavity.

[0009] Optionally, the tops of the two U-shaped stirring tubes are jointly fixed with a horizontal movable ring, which is rotatably mounted on the bottom surface of the connecting cavity and sealed.

[0010] Optionally, the movable ring is located inside the connecting cavity, and the outer side of the connecting cavity is connected to the cooling cavity located at the top via a pipe.

[0011] Optionally, the water distribution tank is hollow inside, and the connecting pipe is connected to multiple water distribution pipes.

[0012] Optionally, the cooling chamber is located at the position of the water distribution tank, forming two ends, and the two ends of the cooling chamber are respectively connected to the connecting pipes on the two water distribution tanks, forming water inlet and water outlet through the two water distribution tanks respectively.

[0013] Optionally, the movable ring is provided with a water inlet that connects to the inside of the U-shaped stirring tube.

[0014] Optionally, the top of the tank is provided with a feed inlet, the bottom midpoint of the tank is provided with a discharge outlet, and the bottom edge of the tank is provided with at least three support feet.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation of the water distribution tank and the multiple cooling chambers in the interlayer of the tank, the cooling water can be evenly distributed into the multiple cooling chambers through the water distribution tank, thereby forming multiple cooling water channels in the tank and ensuring the cooling effect of the cooling water.

[0017] In the above solution, thanks to the cooperation of the motor, stirring shaft, U-shaped stirring tube, moving ring and connecting cavity, the U-shaped stirring tube can be connected to the cooling cavity. While the fructose material in the tank is stirred by the U-shaped stirring tube, the cooling water flowing through it is used to further cool it down. Compared with the existing technology that uses a single jacket to cool from the outside to the inside, the U-shaped stirring tube can also cool the material located in the middle of the tank, further improving the cooling effect.

[0018] In summary, this device employs multi-turn uniform flow cooling and simultaneous stirring cooling, which effectively improves the uniformity of cooling, facilitates the crystallization efficiency of fructose, and yields excellent results. Attached Figure Description

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a crystallization tank for fructose production, including a tank body 1. The top of the tank body 1 is provided with a feed inlet 101, the bottom midpoint of the tank body 1 is provided with a discharge outlet 102, and the bottom edge of the tank body 1 is provided with three support feet 103.

[0033] Two parallel vertical water distribution tanks 2 are fixed on one side of the tank body 1. A connecting pipe 201 is fixed on the outer side of each of the two water distribution tanks 2. Multiple water distribution pipes 202 for extending into the interlayer of the tank body 1 are fixed on the inner side of each water distribution tank 2. The internal interlayer of the tank body 1 is divided into multiple cooling chambers 3 from top to bottom. The multiple cooling chambers 3 are respectively connected to the water distribution pipes 202 at corresponding positions.

[0034] The water distribution tank 2 is hollow inside, and the connecting pipe 201 is connected to multiple water distribution pipes 202, allowing the water distribution tank 2 to receive cooling water externally through the connecting pipe 201 and to distribute the water through the water distribution pipes 202. The cooling chamber 3 is located at the water distribution tank 2 and is divided into two ends, with each end connected to a connecting pipe 201 on one of the two water distribution tanks 2. The two water distribution tanks 2 form an inlet and an outlet for water, respectively. Therefore, the multiple cooling chambers 3 inside the tank 1 form multiple cooling water cooling channels, which can improve the cooling effect.

[0035] Cooperate Figure 4As shown, the top of the tank 1 is provided with an annular connecting cavity 4, which is connected to the cooling cavity 3 located at the top. A motor 5 is fixed to the top of the tank 1, the shaft of the motor 5 extends into the tank 1, and a vertical stirring shaft 6 is fixed thereon. A U-shaped stirring tube 7 adapted to the inner cavity of the tank 1 is fixed to the bottom of the stirring shaft 6, and the top of the U-shaped stirring tube 7 is connected to the connecting cavity 4.

[0036] Specifically, a horizontal movable ring 8 is fixed to the top of both U-shaped stirring tubes 7. The movable ring 8 is rotatably mounted on the bottom surface of the connecting cavity 4 and is sealed. The movable ring 8 is located inside the connecting cavity 4, and the outer side of the connecting cavity 4 is connected to the cooling cavity 3 located at the top through several pipes. The movable ring 8 has a water inlet 801 that connects to the inside of the U-shaped stirring tube 7. Therefore, the cooling water in the cooling cavity 3 located at the top will also flow into the U-shaped stirring tube 7 through the connecting cavity 4, and with the rotation and stirring of the U-shaped stirring tube 7, it will cool and crystallize the fructose material located in the middle of the tank 1, further improving the cooling effect.

[0037] The working principle provided by this utility model is that, in use, the crystallization tank for fructose production has multiple rings of cooling chambers 3 arranged in the interlayer of the tank body 1. Each ring of cooling chamber 3 is evenly connected to two water distribution boxes 2, so that cooling water can be evenly distributed into the multiple rings of cooling chambers 3 through the water distribution boxes 2, thereby forming multiple rings of cooling water channels in the tank body 1 to ensure the cooling effect of the cooling water.

[0038] Meanwhile, as the motor 5 drives the U-shaped stirring tube 7 to stir the fructose material in the tank 1, the cooling chamber 3 located at the bottom will send cooling water into the connecting chamber 4 through a pipe, and then into the U-shaped stirring tube 7 through the water inlet 801 on the movable ring 8, so that the U-shaped stirring tube 7 is also filled with cooling water. Thus, while using the U-shaped stirring tube 7 to stir the fructose material in the tank 1, the cooling water flowing through it can be used to further cool it down. Compared with the existing technology that uses a single jacket to cool from the outside to the inside, the U-shaped stirring tube 7 can also cool the material located in the middle of the tank 1, further improving the cooling effect.

[0039] In summary, this device employs multi-turn uniform flow cooling and simultaneous stirring cooling, which effectively improves the uniformity of cooling, facilitates the crystallization efficiency of fructose, and yields excellent results.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
