Description

Technical Field

[0001] This utility model relates to the field of maltol preparation technology, specifically a distillation apparatus for the preparation of natural maltol. Background Technology

[0002] Maltol is a white to slightly yellow crystalline compound with a caramel aroma and sweet taste. It is widely used in food, daily chemical and pharmaceutical fields. Natural maltol is mainly prepared by plant extraction or microbial fermentation, but the raw materials are often accompanied by a large number of impurities, which need to be purified by distillation.

[0003] A search revealed a Chinese patent with publication number CN214388939U, which discloses a multifunctional distillation apparatus for ethyl maltol. The apparatus includes a distillation tank, a right-side support leg, a residue cleaning rack structure, a cooling crystallization tank, a left-side support leg, a multi-layer filter rack structure, a uniform feed rack structure, a steam connection pipe, a flange, a spiral tube, a condenser, a discharge frame, an end cap, a moisture discharge valve, and a guide plate. The right-side support leg is welded to the four lower corners of the distillation tank. The residue cleaning rack structure is installed at the lower part of the distillation tank. The cooling crystallization tank is located on the left side of the distillation tank.

[0004] In the above-mentioned technology, the solution in the distillation tank is heated by the design of serpentine heating tubes and annular heating tubes. However, neither serpentine heating tubes nor annular heating tubes can move, resulting in low fluidity of the solution in the distillation tank. This leads to uneven heating of the solution in the distillation tank, resulting in low evaporation efficiency of the distillation device during use. Utility Model Content

[0005] The purpose of this invention is to provide a distillation apparatus for the preparation of natural maltol, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a distillation apparatus for the preparation of natural maltol, comprising a tank, and further comprising:

[0007] There are four trays, which are fixedly connected inside the tank.

[0008] Multiple U-shaped tubes are provided and fixedly connected to the top of the tower plate, with one end of the U-shaped tube connected to the bottom of the tower plate;

[0009] The exhaust pipe is fixedly connected to the top of the tank and communicates with the tank.

[0010] The turbine is connected to the inside of the exhaust pipe.

[0011] A rotating shaft is fixedly connected to the bottom of the turbine. The rotating shaft is rotatably connected to the tower plate. Stirring blades are fixedly connected to both ends of the bottom of the rotating shaft.

[0012] Preferably, an arc-shaped plate is fixedly connected to the top edge of the tower plate, and the surface of the tower plate is provided with multiple through holes.

[0013] Preferably, a baffle is fixedly connected to the opening of the arc-shaped plate of the tower plate, the height of the baffle is lower than the height of the arc-shaped plate, and the four baffles are staggered.

[0014] Preferably, the bottom of the tank is conical, and a heating pipe is fixedly connected to the bottom of the outer wall of the tank, with the heating pipe spirally arranged on the outer wall of the tank.

[0015] Preferably, the tank has a feed pipe at one end of the top and a discharge pipe at the bottom.

[0016] Preferably, a valve is installed at one end of the discharge pipe, and four support legs are fixedly connected to the outer wall of the tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention heats the solution in the tank using a heating tube to generate steam. When the steam flows through the exhaust pipe, it drives the turbine to rotate, which in turn drives the rotating shaft and stirring blades to rotate, thereby stirring the solution in the tank, increasing the fluidity of the solution in the tank, and ensuring that the solution in the tank is heated evenly.

[0019] This invention uses an arc-shaped plate and baffle design to allow some solution to accumulate at the top of the tray, and a U-shaped tube design to allow steam to pass through the tray. When the steam exits from one end of the U-shaped tube, it comes into contact with the solution accumulated on the tray, thereby preheating the solution on the tray and improving the heating efficiency of the subsequent solution.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution: such as Figures 1-5 The distillation apparatus shown includes a tank 1, a tower plate 2, a U-shaped tube 3, an exhaust pipe 4, a turbine 5, and a rotating shaft 6. Four tower plates 2 are fixedly connected inside the tank 1. Multiple U-shaped tubes 3 are fixedly connected to the top of the tower plates 2, with one end of each U-shaped tube 3 communicating with the bottom of the tower plate 2. The exhaust pipe 4 is fixedly connected to the top of the tank 1 and communicates with the tank 1. The turbine 5 is rotatably connected inside the exhaust pipe 4. The rotating shaft 6 is fixedly connected to the bottom of the turbine 5 and rotatably connected to the tower plates 2. Stirring blades 7 are fixedly connected to both ends of the bottom of the rotating shaft 6. A feed pipe 12 is provided at one end of the top of the tank 1, and a discharge pipe 13 is provided at the bottom of the tank 1.

[0028] Specifically, since natural maltol contains many impurities, it needs to be distilled to purify it. First, the maltol solution is injected into the tank 1 through the feed pipe 12. During this process, the solution falls onto the tray 2 and flows until it reaches the bottom of the tank 1. At this point, the bottom of the tank 1 can be heated, causing the maltol in the solution to turn into vapor and move upward. As the vapor moves upward, it passes through the U-shaped pipe 3 through the tray 2 and comes into contact with the solution on the tray 2, thus preheating the solution on the tray 2. When the vapor moves into the exhaust pipe 4, the turbine 5 rotates under the drive of the vapor, which in turn drives the rotating shaft 6 and the stirring blade 7 to rotate. When the stirring blade 7 rotates, it agitates the solution at the bottom of the tank 1, thereby increasing the fluidity of the solution in the tank 1 and ensuring that the solution in the tank 1 is heated evenly, thereby improving the evaporation efficiency.

[0029] An arc-shaped plate 8 is fixedly connected to the top edge of the tower plate 2, and multiple through holes 9 are provided on the surface of the tower plate 2; a baffle 10 is fixedly connected to the opening of the arc-shaped plate 8 on the tower plate 2, and the height of the baffle 10 is lower than the height of the arc-shaped plate 8, and the four baffles 10 are staggered.

[0030] Specifically, the design of the arc plate 8 and baffle 10 allows a portion of the solution to accumulate at the top of the tray 2. The exhaust pipe 4 of the U-shaped tube 3 is located below the baffle 10. Therefore, when steam is discharged from the U-shaped tube 3, it will come into contact with the solution accumulated on the tray 2, thereby improving the preheating effect of the steam on the solution on the tray 2. When the operator continuously injects solution into the tank 1, the liquid level of the solution will exceed the top of the baffle 10 and flow to the bottom of the tray 2. When the injection of solution into the tank 1 stops, the solution accumulated at the top of the tray 2 will gradually flow to the bottom of the tank 1 through the through hole 9. In actual operation, the drainage volume of all through holes 9 on a single tray 2 needs to be much smaller than the water volume injected into the tank 1 so that the solution can accumulate smoothly at the top of the tray 2.

[0031] The bottom of the tank 1 is conical, and a heating pipe 11 is fixedly connected to the bottom of the outer wall of the tank 1. The heating pipe 11 is spirally arranged on the outer wall of the tank 1.

[0032] Specifically, by supplying a high-temperature medium, such as high-temperature steam or hot water, into the heating pipe 11, the bottom of the tank 1 can be heated when the high-temperature medium flows in the heating pipe 11, thereby heating the solution in the tank 1.

[0033] A valve 14 is installed at one end of the discharge pipe 13, and four support legs 15 are fixedly connected to the outer wall of the tank body 1;

[0034] Specifically, when the maltol component in the solution inside tank 1 has evaporated completely, valve 14 can be opened to allow the remaining impurity solution in tank 1 to be discharged through discharge pipe 13.

[0035] Working Principle: Since natural maltol contains many impurities, it needs to be distilled for purification. First, the maltol solution is injected into tank 1 through feed pipe 12. During this process, the solution falls onto tray 2. The arc-shaped plate 8 and baffle 10 on tray 2 allow some solution to accumulate at the top. In actual operation, the drainage volume of all through-holes 9 on a single tray 2 needs to be much less than the inflow volume into tank 1. This ensures that solution accumulates smoothly at the top of tray 2. As the operator continuously injects solution into tank 1, the solution... The liquid level will exceed the top of the baffle 10 and flow below the tray 2 until it falls to the bottom of the tank 1. At this time, a high-temperature medium, such as high-temperature steam or hot water, is supplied to the heating pipe 11. When the high-temperature medium flows in the heating pipe 11, it can heat the bottom of the tank 1, thereby heating the solution in the tank 1. This causes the maltol in the solution to turn into vapor and move upward. During the upward movement of the vapor, it will pass through the U-shaped tube 3 and through the tray 2. When the vapor exits from the U-shaped tube 3, it will come into contact with the solution accumulated on the tray 2, thereby preheating the solution on the tray 2.

[0036] When the steam moves into the exhaust pipe 4, the turbine 5 rotates under the drive of the steam, which in turn drives the shaft 6 and the stirring blade 7 to rotate. When the stirring blade 7 rotates, it agitates the solution at the bottom of the tank 1, thereby increasing the fluidity of the solution in the tank 1 and ensuring that the solution in the tank 1 is heated evenly, thus improving the evaporation efficiency. When the injection of solution into the tank 1 stops, the solution accumulated at the top of the tray 2 will gradually flow to the bottom of the tank 1 through the through hole 9. When the maltol component in the solution in the tank 1 has evaporated completely, the valve 14 can be opened, so that the remaining impurity solution in the tank 1 can be discharged through the discharge pipe 13.
