用途及简介

1、DMH 系列净化对开门干燥灭菌烘箱，适用于只要行业的西林瓶，安瓿瓶、铝盖、金属及玻璃器皿件灭菌去热原和固体材料干燥灭菌。

2、DMH 系列净化对开门烘箱，控制系统先进灵敏、配备的可编程序控制器PLC人机界面触摸屏、微压差计、自动排湿阀门及特殊环境使用易燃气体浓度测试仪等一批关键元件均为日本、美国及中国台湾产。使烘箱的质量得到保障，完美的百级层流净化系统符合“GMP”规范要求。

3、DMH 系列产品可供用户选择，在配置和尺寸方面也可根据用户工艺要求、场地、产量订制。

4、工作原理：将装满物料的红盘、瓶子或小车放入箱内，启动PLC可编程序控制系统，内循环风机工作，加热，蝶阀同时开启，干燥箱迅速升温。在内循环风机作用下，热空气通过耐高温高效过滤器进入箱体，在微孔调节板作用下形成一个均匀分布空气向箱内传递，干燥空气洗手瓶子（物料、物品）表面的水分，进入加热通道蒸发排出、干空气在风机作用下定向循环流动，水蒸气排出。随着水蒸气逐渐减少、同时间隙性补充新鲜过滤空气，箱体内呈微正压状态，恒温借宿，过程控制完毕，开启送风或进水强制冷却，自动蝶阀进入关闭状态，声光提示开门出瓶。

Usage and Brief Introduction

1. DMH series purifying split-door drying sterilizing ovens are applicable to the bacteria-killing, pyrogen-removing and drying sterilization of solid objects such as Schering bottles, ampoule bottles, aluminum caps and metal or glass vessels.

2. DMH series purifying split-door ovens are the products of a new generation which have been developed in recent years by our company and have all passed certification in hundreds of pharmaceutical enterprises in China. The control system of the equipment is advanced and sensitive. A BATch of key components such as PLC programmable controller, man-machine interface touch screen, micro-manometer, automatic moisture-expelling valves, inflammable gas concentration tester and so on are all made in Japan, USA or Chinese Taiwan, thus providing a guarantee to the quality of the products. The perfect 100grade laminar flow purifying system conforms to the requirement of GMP norms.

3. DMH series products offer a choice of selection to the users. In terms of configuration and size, the product can be customized according to the usage, site, output and so on required by the users.

4. Operating principle: Place the baking pallets, bottles or trolley lOAded with the materials or objects into the oven and start PLC programmable control system. The blower for internal circulation operates; and heating starts. At the same time, the butterfly valve opens; and the temperature inside the drying oven rises rapidly. Under the action of the blower for internal circulation, dry hot air enters into the oven body through the high-temperature-resisting and high-efficiency filters. Under the action of micro-porous regulation, a homogeneously-distributed air is formed for transmission into the oven body. The dry air absorbs the moisture remaining on the surfaces of bottles（materials or objects）for its entrance into the heating channel, resulting in evaporation and outward expulsion. The dry air flows in directional circulation under the action of the blower for expulsion of water vapor. With the gradual reduction of water vapor and the simultaneous intermittent supplementation of fresh filtered air, the inside of the oven body exhibits the state of micro positive pressure. With the termination of the constant temperature, the process control coMES to an end. Delivery of air or forced cooling (with flow-in of water) starts; and the automatic butterfly valve enters the state of closure, giving an audio and visual alarm for opening the door and removing the bottles.
