摘　　要：针对鱿鱼足人工裹粉时粉料容易受潮、利用率低,且鱿鱼足表面粉层分布不均匀、容易漏裹的问题,提出利用气流输送粉料、施加高压静电使粉料带上电荷进行鱿鱼足裹粉的方法。为研究相对湿度和静电电压对鱿鱼足裹粉速度和裹粉量的影响,以及鱿鱼足表面粉料的附着效果,设计了试验装置,设置了40%、60%、80%3种相对湿度和0、30、60、90 k V 4种静电电压,进行了不同相对湿度和静电电压下的鱿鱼足静电裹粉试验和离心式附着效果测试试验。结果表明:施加高压静电可提高裹粉速度和裹粉量;相对湿度为40%、静电电压为30 k V时,裹粉速度最快、裹粉量最大;相对湿度为60%时,提高静电压可显著提高裹粉速度和裹粉量;相对湿度为80%时,不同静电压下裹粉速度和裹粉量差异不明显;0~1 s内裹粉量增加最快,相对湿度为40%时,在0~0.5 s时间段内裹粉量的增加最显著;在相对湿度为60%、静电电压60 k V时进行鱿鱼足裹粉,粉料的附着效果较好。Adding seasoning powder to the surface of squid tentacles can increase its flavor and improve the appearance and taste after processing. At present,powder coating of squid tentacles are mainly done by manual work in Chinese aquatic products processing plants,the labor intensity is high,but the work efficiency is low. There were some deficiencies in the artificial squid tentacles coating,for example,in the process of coating,some powder was soaked by surface water on squid tentacles,which led to waste of powders because they can not be used again. Also,it was likely that the artificial coating of squid tentacles cause food contamination. During the process of coating,some areas were prone to be uncoated,and the thickness of the powder layer was not consistent. A new method of using air flow for powder conveying and applying high-voltage static electricity to charge the powder was proposed for powder coating. Due to the principle of that the same charges were repellent,the powder layer on squid tentacles surface was uniform. To obtain optimal coating conditions,electrostatic powder coating experimental device was designed and three relative humidities（ RH） of 40%,60%,80% and four voltages of 0 k V,30 k V,60 k V and 90 k V were setted for electrostatic powder coating test. The results of electrostatic coating experiments showed that the high-voltage static electricity can improve the coating speed and increase the coating mass,the increase of static voltage can significantly increase the coating speed and the coating mass with relative humidity of 60%,the coating effect was not significant when RH was 80%,the coating speed was the fastest and the coating mass was the maximum with voltage of 30 k V and relativehumidity of 40%. During the stage of 0 ～ 1 s,the amount of coating mass was increased the fastest,when relative humidity was 40%,the increase of coating mass was the most significant in 0 ～ 0. 5 s. To compare the adhesion effect under different coating conditions,a centrifugal device was designed and ma
