美国索纳汀(SONOD-YNE)公司最近研制成功一种用于鱼粉生产的声波干燥设备。其特点是结构简单,没有运动部件,操作维修方便,效率高,节省能源,蒸发每公斤水份只需720—830千卡的热量,而通常的间接加热干燥设备则需1000——1400千卡的热量。干燥时间短,从原料到加工成成品仅需5分钟,所制得的鱼粉质量好,得率高,蛋白质,维生素等营养成份损失很少。声波干燥设备(又称SONUS)的主要工作部件是脉冲喷射器,其结构见图1。燃烧室(1)上有燃料进口(2),空气进口(3),电火花引
SONOD-YNE recently developed a sonicator for fishmeal production. Its characteristics are simple structure, no moving parts, easy operation and maintenance, high efficiency, energy saving, evaporation per kilogram of water only 720-830 kcal of heat, while the usual indirect heating and drying equipment will need 1000--1400 kcal The heat. Drying time is short, from raw materials to processed into finished products just 5 minutes, the quality of the prepared fish meal, high yield, protein, vitamins and other nutrients loss is very small. Sonic drying equipment (also known as SONUS) is the main part of the pulse jet injector, the structure shown in Figure 1. The combustion chamber (1) has a fuel inlet (2), an air inlet (3) and a spark plug
