鱿鱼足静电裹粉装置设计与参数试验优化
Design and Parameters Optimization of Electrostatic Powder Coating Device for Squid Tentacles
摘要
Abstract
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-vohage 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 kV,30 kV,60 kV and 90 kV 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 kV and relative humidity 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 made.The results of the test showed that the adhesion effect of powder was the best when the coating was done with relative humidity of 60% and voltage of 60 kV.The results can provide a reference for the design of later squid tentacles electrostatic coating equipment.关键词
