Pressure Spray Drying Equipment (CE Approved)

1.概述Descriptions

本机组是一种可以同时完成干燥和造粒的装置。按工艺要求可以调节料液泵的压力、流量、喷孔的大小、得到所需的按一定大小比例的球形颗粒。

本机组工作过程为：料液通过隔膜泵高压输入，喷出雾状液滴，然后同热空气并流下降，大部分粉粒由塔底排料口收集，废气及其微小粉末经旋风分离器分离，废气由排风机排出，粉末由设在旋风分离器下端的收粉筒收集，风机出口处还可装备二级除尘装置，回收率在 96-98% 以上。

本机组与物料接触部分的塔体、管道、分离器的材料，均采用 SUS304 制作 。在塔体内部与外壳之间有足够的保温层 ，填充材料为超细玻璃棉，塔体设有观察门、视镜、光源及控制仪表、由电器控制操作台控制和显示。

本机组的热源装置采用蒸汽加热或电加热器，具有操作方便、启动快、结构紧凑、热风干净清洁等优点。另外在电气控制柜内装有电加热器的控制调节装置，使进口温度无级调节。对于缺电地区可采用蒸汽加热或燃煤、燃油热风炉等方式，局部或全部代替电加热装置。本厂可根据用户的实际需要提供不同的加热方式。

The unit is a device that can simultaneously dry and granulate. According to the process requirements can adjust the material pump pressure, flow, the size of the nozzle, get the required size of the spherical particles.

The working process of the unit is: the liquid material feed in through the diaphragm pump with high pressure , spray mist droplets, and then with the hot air co-current decline, most of the powder collected from the bottom of tower , the exhaust and its small powder seperated by the cyclone , the exhaust gas discharged by the exhaust fan, the powder collected by the cyclone separator in the bottom of the collection tube , fan outlet can also be equipped with secondary dust removal device, the recovery rate of 96-98% or more.

The unit in contact with raw material made of SUS304 . There is enough insulation layer between the tower body and the shell, the filling material is ultra-fine glass wool, the tower body has observation door, sight glass, light source and control instrument, controlled and displayed by the touch screen .

The heat source device using steam heating or electric heater, with easy operation, fast start, compact structure, hot air clean and so on. Also in the electrical control cabinet equipped with electric heater control and adjustment device, so that the inlet temperature stepless adjustment. For the power shortage area can be used steam heating or coal, fuel hot air furnace, etc., local or all instead of electric heating device. The factory can be based on the actual needs of users to provide different heating methods.

2、特点Features
