TRAY EAZVAC架式真空干燥机

TRAY EAZVAC架式真空干燥机
很多时候,在化学加工工业,我们面临着困难,物料的干燥由于高毒性的特点,吸湿性质,热敏感。

为了解决上述的问题,使用真空干燥机在以被干燥的物料的沸点放入,整个系统是一个封闭的循环。没有污染时,由于闭合设计。任何演变都在干燥过程中的蒸汽通过一个连接的换热器中被冷却下来,并收集在一个接收容器
EazVac真空干燥机溶剂萃取系统结合时,保证了几乎所有的蒸发蒸气回收和冷凝在一个接收容器是真空的。

工作原理
EazVac真空干燥机基本上是在真空条件下工作的托盘式干燥设备。它干燥的传导原则。有许多其上载的产品的托盘放在干燥机内的货架。最顶部的货架是一个虚拟的货架,以确保适当的加热和阻止干燥的粉末,从到溶剂萃取系统中逸出。

货架制造之间放置的挡板暨加强筋的中空结构。每个架子上有一个入口和出口喷嘴。每个搁板通过这些喷嘴连接到一个入口和出口接头连接器。热介质通过入口的页眉和反过来每个货架。热介质流经蛇形的方式确保传热快的表面,这反过来又加热放置在货架上的托盘货架。热媒体流通过出口从货架上。

入口和出口集管的设计使得平均分配到每一个架子的加热介质的流动。

干燥室被构造从繁重的厚度板,以确保有没有屈曲的真空操作期间。附加嘁线圈中所提供进一步身体变硬,也通过热媒。室设置有具有足够的锁定装置的一个沉重的门。

通过蒸汽柱连接到管壳式换热器,而这又是连接到一个冷凝物接收容器的干燥室。真空被施加到冷凝水的耳麦。蒸气进化后,它被冷却的换热器中,在干燥过程中被收集在接收器。

待冷却的蒸气通过直通的换热器的管侧。当冷却水通过的壳侧。冷却线圈在冷凝液中的接收容器的存在,进一步冷却进入接收容器之前,它是任何蒸汽进入真空泵。

凝结水接收容器被连接到一个真空陷阱,以确保任何未冷却的蒸汽所产生的接收容器被捕获并允许蒸汽很小的内容传递到真空泵。

TRAY EAZVAC SHELF DRYER
Many a times, in the chemical process industries, we are faced with difficulties in drying materials due to high toxic contents, hygroscopic in nature, heat sensitive.

To solve the above problems, vacuum dryers are used where the boiling point of the materials to be dried is brought down and the entire system is in a closed loop. No contamination occurs, due to the closed arrangement. Any vapours evolved during the drying process is cooled down through a connected Heat Exchanger and collected in a reciever
The EazVac Shelf Dryer when combined with a solvent extraction system, ensures that almost all of the evaporating vapours is recovered and condensed in to a reciever which is vacuumised.

Working principle
The EazVac Shelf Dryer is basically a tray dryer working under vacuum conditions. It dries on the conduction principle. There are a number of shelves inside the dryer on which the product laden trays are placed. The top most shelf is a dummy shelf to ensure proper heating and to block dried powder from escaping into the solvent extraction system.

The shelves are manufactured in hollow construction with baffles cum stiffeners placed in between. Each shelf has an inlet and outlet nozzle. Each shelf is connected through these nozzles to an Inlet and Outlet Header. Hot media is passed through the Inlet Header and in turn to each shelf. The hot media flows through the shelves in a serpentine fashion ensuring faster heat transfer to the surface, which in turn heats up the Trays placed on the shelves. The hot media flows out from the shelves through the Outlet Header.

The Inlet and Outlet Headers are designed such that the flow of the heating media is equally distributed into the each of the shelves.

The Dryer chamber is constructed from heavy thickness plates to ensure that there is no buckling during the vacuum operation. Additional limpet coils are provided to further stiffen the body and also to pass the hot media. The chamber is provided with a heavy door with a adequate locking arrangement.

The Dryer Chamber is connected through a vapour column to a Shell & Tube type Heat Exchanger, which in turn is connected to a Condenstate Reciever. Vacuum is applied to the condensate reciver. Vapour evolved during the drying process is collected in the receiveR after it is cooled in the Heat Exchanger.

The vapour to be cooled is passed thru the tube side of the Heat Exchanger. While cooling water is passed thru the shell side. A cooling coil is present in the condensate reciever, to further cool any vapours entering the reciever before it is goes into the vacuum pump.

The Condensate Reciever is connected to a Vacuum Trap, to ensure that any uncooled vapours arising from the reciever is trapped and allowing very minimal contents of the vapour to pass into the Vacuum Pump.

Salient Features of the EazVac Shelf Dryer
