Working principle:
The vertical crystallizer works according to the principle that the solubility of the crystal in solution decreases with the decrease of temperature. According to the production process requirements of different materials, a crystal solution in a subsaturated state or a saturated state is sent to the crystallizer body, and circulating cooling water is passed into the cold removal component. Since the temperature of the circulating cooling water is lower than the temperature of the crystal solution, the solution exchanges heat with the circulating water, the solution temperature begins to decrease, and the solubility of the crystal decreases accordingly. The solute precipitates in a crystal state. The flow of the cooling water takes away the high-temperature solution itself and the crystallization heat generated when the crystal precipitates, causing the solution temperature to continuously decrease and the crystal to continue to precipitate. Thus, the crystallization process is completed.
The vertical continuous crystallizer is different from the horizontal crystallizer. It is a continuous crystallization, which is a transformation process from the liquid phase to the solid phase. This process includes mixing, cooling, crystal cultivation, precipitation, and growth. The sugar liquid enters the cylinder of the crystallizer until it is scraped out, and crystallization is achieved through displacement. During the production process, the feed volume and the discharge volume are basically balanced, and the feed volume can be continuously operated for several months.
During the production process of the vertical crystallizer, the material is in the vertical direction of the cylinder. At different temperatures, the cooling elements are extruded up and downward toward a vertically folded spring-shaped linear movement, and at the same time, the free fall movement is also possible under the action of gravity and static pressure; the material completes the specified stroke and cleanliness, and the temperatures of each place and each cooling interval are different, and the material properties are also different. The crystal content gradually increases from top to bottom, reaching the bottom content is greater than 50%.
For products that require product particle size, the vertical crystallizer can control the precipitation of the crystal. By adjusting the circulating water flow, the solution can be cooled down according to a predetermined crystallization curve to ensure that the crystal particle size meets the requirements and make the particle size uniform.
