SRH type double door hot air circulation oven
1.Introduction
This machine is designed to sterilize and dry various types of rubber stoppers, aluminum lids, and bottle components. It utilizes stainless steel heating rods for rapid heating and employs a direct cooling fan for hot air circulation, ensuring efficient sterilization. The machine features automatic display and control settings, enabling users to monitor and record temperature parameters. Additionally, it includes alarms for over-temperature and timely alerts. Equipped with a high-temperature 100 clean device in the hot air circulation area, it complies with GMP specifications. The two-door design, along with an interlock device, guarantees adherence to cleanliness requirements in the designated area.
2.Function
1. The maximum temperature in the oven work area is 350 ℃.
2. The operating temperature is set at 200 ℃, with actual fluctuations within ± 2-3 ℃. The touch screen display allows users to maintain a constant temperature at 200 ℃.
3. During normal operation, the initial heating phase is accompanied by automatic opening of the air duct valve to discharge moisture. Once the set temperature is reached, the insulation phase begins, during which the door is closed. Upon reaching the set time, the system automatically enters the forced air cooling phase.
4. Forced air cooling involves opening the outlet valve and activating the high-temperature exhaust fan, while the circulating fan continues to operate (it is not shut off). This process facilitates rapid cooling of the oven as hot air is gradually replaced by cooler external air. The inlet and outlet of the airflow are equipped with hundred filters to prevent the entry of dirty air during insulation or inactive phases.
5. The touch screen interface provides real-time monitoring of the circulating fan, exhaust fan, heating pipe, inlet valve, and outlet valve, displaying their current operational status.
