The quality of the oven is guaranteed. The perfect hundred level flow purification system meets the requirements of GMP standards

3. The DMH series products are available for users to choose from, and the configuration and size can also be customized according to the user's purpose, venue, production volume, etc

4. Working principle: Put a baking tray, bottle, or cart filled with materials into the box, start the PLC programmable control system, the internal circulation fan works, heats, and the butterfly valve opens simultaneously, and the drying box quickly heats up. Under the action of the internal circulation fan, hot air enters the box through a high-temperature and high-efficiency filter, forming a uniformly distributed air that is transferred to the box under the micro pore regulation. Dry air absorbs the moisture on the surface of the bottle (material, item), enters the heating channel for evaporation and discharge, and dry air circulates in a directional manner under the action of the fan, while water vapor is discharged. As the water vapor gradually decreases and fresh filtered air is intermittently replenished, the inside of the box is in a positive pressure state, the constant temperature ends, and the process control is complete. Turn on the air supply or (water inlet) forced cooling, the automatic butterfly valve enters the closed state, and the sound and light prompt opens the door to discharge the bottle

Suitable for drying and sterilization of pharmaceutical glass bottles such as injection ampoules, penicillin bottles, and oral liquids in pharmaceutical factories, it has the characteristics of fast heating, uniform heat distribution, compact structure, and simple operation. The entire system is controlled by PLC and has functions such as process display, data and operation recording, fault display, etc., achieving automatic program control for temperature rise, insulation, moisture removal, and ventilation.

A plate filled with bottles (or materials) is placed into the box, and the PLC program control system is started. The heating system starts working, and the electric butterfly valve opens simultaneously. The temperature rises rapidly, and water vapor is quickly discharged from the opening of the electric butterfly valve. As the water vapor gradually decreases, the electric butterfly valve automatically closes, and fresh air is continuously replenished through a high-temperature resistant filter to form a balanced state inside the box

The heated dry air generates slight pressure under the action of the hot air fan, and enters the box through a high-temperature and high-efficiency filter. Under the action of the buffer fine-tuning plate, a uniform distributed airflow is formed and transmitted to the box. The hot dry air absorbs the moisture on the surface of the bottle and enters the exhaust channel for evaporation and discharge. The dry air circulates in a directional manner under the action of the hot air fan, and works in a sequential and timed manner to achieve sterilization and drying effects
