Elaborate washing machine and attendant handling lemons for the Exchange Products Company in Corona, California, ca.1930

Photograph of an elaborate washing machine and attendant handling lemons for the Exchange Products Company in Corona, California, ca.1930. The company produces citric acid, oil of lemon, pectin, etc. The man faces the background in lightly-colored coveralls and a hat as he works lemons through the large washing machine in front of him. The lemons appear to enter the machine from a conveyer belt near the ceiling on the left, get hand washed by the attendant, fall on the right to a pool with three rollers below and flow towards the left. Water has spilled into the foreground where a stool stands to assist the attendant to the machine.

本照片拍摄于约1930年，展现了加利福尼亚州科罗纳市Exchange Products Company厂区内，一台精巧的大型柠檬清洗机与操作人员处理柠檬的场景。该公司主营柠檬酸、柠檬精油、果胶等产品。画面中，操作人员身着浅色工装、头戴帽子，背向取景背景，正操作身前的大型清洗机处理柠檬：柠檬从左侧靠近天花板的传送带送入设备，经手工清洗后落入右侧下方带有三个滚筒的水槽，并向左流动。画面前景区域有水溢出，一旁放置了一张高脚凳，方便操作人员靠近设备。
