马铃薯去皮机设计 摘要 在很多蔬菜和水果的加工中，都需要进行去皮处理，从而除去不需要的部分来改善食用和外观。为了降低成本和避免浪费，去皮要求尽量减少可食用部分的丢失。这里，介绍摩擦去皮方法：将果蔬放在旋转圆筒内，在圆筒内壁（焊接金刚砂）的摩擦作用下，将表皮除去，同时用水冲洗。在电动机带动下，通过齿轮和传动轴带动圆盘旋转，圆盘表面有凸起部分，当马铃薯落入圆盘时，产生上下翻滚同时在离心力作用下与圆筒内壁摩擦作用，圆筒内壁焊接有金刚砂棒，保证去除马铃薯的表皮，而圆盘结构使得马铃薯上下翻滚从而表面与圆筒充分接触，大大减小了去皮的死角。启动装置的同时用喷着从圆筒上方喷入清水，及时将皮屑冲洗并顺着清洗槽排除，保证装置的正常运行，提高去皮的效率。同时这种方法的优点是室温下进行，耗能低，成本低廉，造成浪费少。 关键词：马铃薯;去皮机;机械设计；食品机械 Abstract I
