Electric blast drying oven temperature suddenly too high those solutions?
Excessive temperature refers to the phenomenon that when the electric blast drying oven is first started up, the studio temperature exceeds the set temperature above 5℃, and then slowly decreases and stabilizes at the set temperature. Some pharmaceutical, biological, chemical, food, electronics and other industries are more sensitive to this phenomenon.
Although there is no limit index of temperature overshoot in the standard of electric blast drying oven, with the continuous improvement of control technology, the temperature overshoot of electric blast drying oven has been generally controlled below 2 ~ 3℃.
It is impossible to eliminate temperature overshoot completely. There are ways to bring the temperature overshoot to an acceptable level. Here are two options for users who have previously bought older products:
1. Empty container constant method; An empty box raises the temperature of the workshop to the required drying temperature and stabilizes it. Then the samples are quickly put into the workshop. This method should protect the operator from scalding. Pay more attention to the volatiles of the baked products because of volatile too fast and may produce new hazards.
2. Two-stage temperature rise method; First set the temperature of the instrument at 5-10 ℃ away from the required temperature difference, and then reset the temperature of the instrument at the required drying temperature after stabilization.
Proper use of oven
There are many kinds of electric drying oven, explosion-proof drying oven, electric heating blast drying oven and so on. Simply speaking, it is to use an adjustable and controllable heater to heat the heating items in a specific environment at a fixed temperature and time. The heater is usually heated by electric wire or quartz tube. The heating is controlled by a timer and an adjustable temperature switch [adjustable or power selected]. The other is over - temperature protection, generally by jumping - type temperature switch to complete.
