First of all, the principle: electric thermostatic drying oven through the heating element of the gas or solid samples heated to the required temperature, maintained for a certain period of time, through appropriate ventilation or moisture absorption and other measures, so that the sample to achieve the desired drying effect. In addition to all the features of the electric constant temperature drying oven, the electric constant temperature drying oven also has the function of blower to force the samples to be circulated and dried.
Secondly, the characteristics: electric constant temperature drying oven has precise constant temperature control system, high precision temperature control, smooth operation, low power consumption, suitable for drying volatile substances and the need to maintain the shape of the sample of the goods. And the electric constant temperature blast drying oven not only has all the features of electric constant temperature drying oven, but also has the function of forced circulation drying of the samples with the blast, which can better improve the drying efficiency of the samples, and it is suitable for large-scale production and industrial fields.
Finally, the scope of application: electric constant temperature drying oven is suitable for drying samples in the laboratory, such as fibers, rubber, pharmaceuticals, food, chemical raw materials, metals, plastics, and other solid items and some chemical reagents, such as volatile or moisture-absorbent items of constant temperature drying. And the electric constant temperature blast drying oven is suitable for large-scale manufacturing and industrial fields, such as food, medicine, chemical, pharmaceutical, metallurgy, electronics, electrical appliances and other production links in the sample drying items.
In general, the blower drying oven and electric drying oven in principle, characteristics and scope of application of the differences, need to choose according to specific needs.
