Description

Technical Field

[0001] This utility model relates to the field of tagatose fermentation technology, and in particular to a stirring structure for a tagatose fermentation device. Background Technology

[0002] Taat sugar is a multifunctional healthy sugar, mainly derived from lactose in milk. Its taste is similar to sucrose, perfectly satisfying people's innate love of sweets. Taat sugar is a boon for people with diabetes, obesity, sub-health conditions, or those pursuing a healthy lifestyle. It allows these groups to continue enjoying sweets despite health concerns, improving their quality of life and enabling them to live a healthy life accompanied by rich, sweet flavors.

[0003] Publication No. CN221868441U discloses a reaction apparatus for tagatose, relating to the technical field of compound reaction equipment. It includes a reaction vessel body, a combined cover, an emulsifier structure, and a stirring shaft structure. The emulsifier shaft is connected to the output end of a first motor, and crushing components are symmetrically arranged on the outside of the emulsifier shaft. The stirring shaft is connected to the output end of a second motor, and an anchor-type component is installed at the bottom end of the stirring shaft. This invention, by incorporating components such as the emulsifier structure and the stirring shaft structure, utilizes a combination of reaction stirring and emulsifier in its tagatose reaction vessel compared to traditional reaction vessels. This significantly improves the contact between reactants and greatly increases the dispersion of materials in the system, promoting the reaction. It effectively solves the problem of the intermediate state where the polyhydroxyl groups of sugar compounds mix with water, resulting in a viscous mixture that is almost impossible to stir with traditional methods.

[0004] In existing technologies, although stirring devices can mix the substances in the tank evenly, continuous stirring generates heat and does work on the stirred substances, further increasing their temperature. Temperature changes can easily affect the fermentation of tagatose. Therefore, there is a need to propose a stirring structure for a tagatose fermentation device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where continuous stirring generates heat and does work on the stirred substance, further increasing its temperature, which can easily affect the fermentation of tagatose. Therefore, this invention proposes a stirring structure for a tagatose fermentation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stirring structure for a tagatose fermentation device includes a fermentation tank with a feed hopper at the top. A pair of cooling and stirring mechanisms are installed inside the fermentation tank. A drive mechanism for rotating the pair of cooling and stirring mechanisms is located at the top of the fermentation tank. A circulating liquid delivery mechanism is also located at the top of the fermentation tank. Each cooling and stirring mechanism includes a pair of rotating tubes installed inside the fermentation tank. The top and bottom ends of the pair of rotating tubes rotatably penetrate the top and bottom ends of the fermentation tank, respectively. Several sets of stirring blades are evenly and uniformly fixedly installed on the pair of rotating tubes. The sets of stirring blades on the pair of rotating tubes are staggered. Cooling chambers are formed inside the stirring blades and are connected to the rotating tubes.

[0008] This device is used to cool the materials in the fermentation tank while stirring them. External liquid enters the rotating tube and is simultaneously transported to the cooling chamber inside the stirring blade. As the rotating tube drives the stirring blade to rotate, it stirs the materials. The liquid in the rotating tube and the cooling chamber cools the materials and absorbs the heat generated during the stirring process, preventing the heat from affecting the fermentation of tagatose.

[0009] Preferably, the driving mechanism includes a fixed mounting frame fixedly installed on the top of the fermenter, a drive motor fixedly installed inside the fixed mounting frame, a drive gear coaxially fixedly connected to the output shaft of the drive motor, a pair of driven gears symmetrically arranged on both sides of the drive gear, the pair of driven gears meshing with the drive gear, and the pair of driven gears respectively coaxially fixedly connected to the top ends of a pair of rotating tubes;

[0010] Used to drive the rotating tube to rotate, start the drive motor, drive the drive motor to drive the drive gear to rotate, drive the drive gear to drive a pair of driven gears to rotate, and the pair of driven gears to drive a pair of rotating tubes to rotate.

[0011] Preferably, the circulating infusion mechanism includes a pair of upper rotating joints and a pair of lower rotating joints. The pair of upper rotating joints are rotatably installed at the top of a pair of rotating tubes, and an inlet pipe is rotatably installed at the top of the pair of upper rotating joints. The pair of lower rotating joints are rotatably installed at the bottom of a pair of rotating tubes, and a drain pipe is rotatably installed at the bottom of the pair of lower rotating joints.

[0012] A circulation pump is fixedly installed at the top of the fermenter. The circulation pump is connected to a liquid extraction pipe and a liquid delivery pipe. The liquid extraction pipe is connected to a water source, the liquid delivery pipe is connected to a pair of liquid inlet pipes, and the end of the liquid outlet pipe is connected to a water source.

[0013] The connection between the upper rotary joint and the rotary pipe and the inlet pipe is sealed, and the connection between the lower rotary joint and the rotary pipe and the outlet pipe is sealed.

[0014] This device is used to circulate and transport liquid from the water source into the rotating pipe. When the circulation pump is started, the liquid in the water source passes through the suction pipe, delivery pipe and inlet pipe in sequence, and then through the upper rotating joint into the rotating pipe. Finally, it returns to the water source through the lower rotating joint and the drain pipe. This cycle repeats continuously. At the same time, the rotation of the upper and lower rotating joints prevents the liquid from being transported smoothly when the rotating pipe rotates.

[0015] Preferably, the bottom of the fermentation tank is connected to a discharge pipe, an electromagnetic valve is fixedly installed on the discharge pipe, and several support legs are fixedly installed at the bottom of the fermentation tank.

[0016] Used to discharge fermented tagatose from the discharge pipe.

[0017] This utility model has the following beneficial effects:

[0018] 1. By setting up a cooling and stirring mechanism, external liquid enters the rotating tube and is simultaneously transported to the cooling chamber inside the stirring blade. When the rotating tube drives the stirring blade to rotate, it stirs the material. The liquid in the rotating tube and the cooling chamber cools the material and absorbs the heat generated during the stirring process, thus preventing the heat from affecting the fermentation of tagatose.

[0019] 2. By setting up a circulating infusion mechanism and starting the circulating pump, the liquid in the water source passes through the suction pipe, infusion pipe and inlet pipe in sequence, and then is transported to the rotating pipe through the upper rotating joint. Finally, it returns to the water source through the lower rotating joint and the drain pipe. This cycle repeats continuously. At the same time, the rotation of the upper and lower rotating joints prevents the liquid from being transported smoothly when the rotating pipe rotates. Attached Figure Description
