卧螺离心机是实现籽瓜全利用加工生产线下游工艺中籽瓜皮瓤混合液固液分离的核心设备，其分离性能的好坏直接影响到后续设备的分离效果，从而最终影响到籽瓜皮瓤的利用率和产品品质.针对这一问题，以适用于籽瓜全利用加工生产线的 LW450×1800—N 型卧螺离心机，依据影响其分离效果的主要性能参数，对其工作性能进行正交试验研究.结果表明：影响卧螺离心机清液含固率的主次因素依次为：转鼓转速、转鼓与螺旋差转速、液位差半径；影响卧螺离心机清液还原糖保留率的主次因素依次为：转鼓转速、液位差半径、转鼓与螺旋差转速.综合考虑试验因素对卧螺离心机分离性能的影响大小与生产工艺要求，卧螺离心机的优化工作参数为：转鼓转速为2500 r/min、转鼓与螺旋差转速24 r/min、液位半径154 mm.重复试验验证结果表明：最优参数工作下的清液含固率为2.28%，还原糖保留率为96.69%.

Decanters is the key equipment to achieve watermelon flesh mixed skin solid-liquid separation in downstream processes of production line of full use of watermelon,the separation performance has a di-rect impact on the subsequent separation equipment,which ultimately affects the watermelon flesh mixed skin utilization and product quality.To solve this problem,to apply to LW450 × 1800-N-type Decanters of the production line,according to the separation of the effects of its main performance parameters,orthogo-nal experimental study on its performance.The results showed that the primary and secondary factors of affect the serum-containing solid rate of Decanters were as drum speed,drum and the screw speed differ-ence,level difference radius.The primary and secondary factors of affect the sugar retention rate of decant-ers were as drum speed,level difference radius,drum and the screw speed difference.Considering the exper-imental factors on the separation performance of decanters and production process requirements,optimize operating parameters of decanters were as drum speed of 2 500 r/min,drum and the screw speed difference of 24 r/min,level difference radius of 154 mm.Repeated test validation results showed that worked under the optimal parameters,the supernatant containing solid rate was 2.28%,the sugar retention rate was 92.69%.
