柠檬渣澄清甘蔗汁的研究

Study on clarification of sugarcane juice with lemon slag

摘要: 为了提高甘蔗汁的透光率,研究了用改性柠檬渣对甘蔗汁进行澄清。利用单因素考察改性柠檬渣的用量、振荡时间、振荡温度和振荡速度对甘蔗汁透光率的影响。并在此基础上设计了L9(34)振荡正交实验和离心实验。实验结果表明加入改性后的柠檬渣能明显提高甘蔗汁的透光率;最优振荡组合:振荡时间为70 min,振荡温度为30℃,振荡速度为100 r/min,40 m L甘蔗原汁中加入改性柠檬渣用量为0.1 g;最优离心组合为:离心机转速为7000 r/min,离心时间为15 min,离心次数为1。在此工艺条件下的甘蔗汁的透光率可达到94.7%。

Abstract: The sugarcane juice was clarified by the modified lemon slag in order to improve its transparency. The dosage of the modified lemon slag,vibration time,vibration temperature and speed were studied respectively.L9( 34) about the vibration and centrifugation experiments were studied on the base of the effect conditions above.The results showed that the transparency of sugarcane juice was improved obviously when the modified lemon slag was added. The optimum vibration time,the temperature and the speed were 70 min,30 ℃ and 100 r / min respectively.The transparency could be increased to 94.7% at the optimum centrifugation conditions( 7000 r / min,15 min) by adding lemon slag( 0.1 g) modified to the original sugarcane juice( 40 m L).
