Description

Technical Field

[0001] The invention relates to the technical field of aspartame production equipment, in particular to a novel cooling device used in aspartame production. Background Art

[0002] Aspartame is a non-carbohydrate artificial sweetener with poor thermal stability. It is relatively stable below 55°C and relatively stable between pH 2 and 4. Its hydrochloride has a large solubility. In the current aspartame neutralization crystallization reaction device, in order to prevent the local pH of the aspartame hydrochloride solution from exceeding the standard and causing new impurities to be generated, it is generally stirred by a stirring device when the alkali solution is added. The neutralization reaction generally releases a large amount of heat when it occurs. If there is no cooling device, the mixed solution will cause the aspartame to decompose due to the high temperature.

[0003] The existing Chinese patent with the announcement number CN216172281U discloses a neutralization reaction device for aspartame production, including a neutralization tank body loaded with aspartame hydrochloride solution, a feed port for adding aspartame hydrochloride solution connected to the tank top of the neutralization tank body, and a neutralization mechanism for neutralizing the aspartame hydrochloride solution installed on the neutralization tank body; the neutralization mechanism includes a stirring tube with a sealed lower end, the stirring tube is rotatably connected to the center of the tank top of the neutralization tank body through a sealed bearing, and the two ends of the stirring tube pass through the sealed bearing and extend outward, the stirring tube located outside the neutralization tank body is connected to the tank top of the neutralization tank body through a drive assembly, and a plurality of stirring blades are fixedly sleeved on the tube wall of the stirring tube located inside the neutralization tank body at uniform and equidistant intervals in the vertical direction.

[0004] Regarding the above-mentioned related technologies, it is found that during the existing aspartame production and stirring process, The tank's heat dissipation relies primarily on natural heat dissipation, which is slow and prevents timely heat dissipation, thus affecting the normal production of aspartame. Furthermore, traditional impellers have a simple structure, typically consisting of a single blade, resulting in poor stirring and inadequate mixing of the material. This prevents the material from evenly contacting the cooling tube during the cooling process, leading to uneven cooling quality and ultimately affecting the quality of aspartame.
