摘要/Abstract

摘要： 以葡萄糖酸钙为研究对象进行了真空降温结晶实验，考察了温度、搅拌速率以及真空度等因素对葡萄糖酸钙真空冷却结晶的影响。结果表明，影响葡萄糖酸钙结晶率的因素先后顺序是真空度、结晶温度、转速，并且真空度的P值小于0.05，具有显著性。葡萄糖酸钙真空冷却结晶的最优工艺条件为结晶温度50 ℃、真空度0.095 MPa、转速100 r/min，该研究为葡萄糖酸钙真空闪发连续蒸发结晶技术与装置开发提供理论依据

Abstract: With calcium gluconate as the research object, a vacuum cooling crystallization experiment was performed to investigate the effects of time, temperature, stirring speed, and vacuum degree on the vacuum cooling crystallization of calcium gluconate. Results show that the factors affecting the crystallization rate of calcium gluconate are listed in the order of desceding degree of impact as vacuum degree, crystallization temperature, and stirring speed, among which the vacuum degree is a significant factor with P<0.05. The optimal process conditions for vacuum cooling crystallization of calcium gluconate are as follows: crystallization temperature is 50 °C, vacuum degree is 0.095 MPa, and stirring speed is 100 r/min. These results provide theoretical basis for technology and device development of calcium gluconate vacuum flash continuous evaporation crystallization.

Key words: calcium gluconate, vacuum cooling crystallization；crystallization temperature;stiring speed
