With the rapid development of science and technology, the application of electric blast drying ovens is becoming more and more extensive, and it is also highly valued by environmental test equipment manufacturers. Beijing Yashilin brand drying ovens have first-class quality and excellent performance. They are laboratory drying and baking. And one of the ideal choices for sterilization, when choosing an electric blast drying oven, you need to pay attention to the following points:
1. There are two types of electric blast drying oven: desktop structure and vertical structure. Desktop structure (desktop electric blast drying oven) means that the cabinet and auxiliary cabinet (control panel) are distributed on the left and right, the air duct is located on the rear side, the wind forms horizontal convection in the working room, and the studio volume is from 30L to 240L The vertical structure (vertical blast drying box) box and auxiliary box are distributed up and down, the wind forms vertical convection in the working chamber, and the volume of the vertical structure studio is from 30L to 620L or more.
2. The selection of the size of the electric blast drying box: the size of the working room can be determined according to the size and number of the test items. During the drying process, the number and arrangement of laboratory test items affect the uniformity of the temperature in the working room. When the requirements for temperature uniformity are relatively high, it is recommended to reduce the number of samples or choose a larger type of drying oven to ensure hot air convection in the working room. The sample specimens should maintain a gap of 2 ~ 3cm or more from the inner wall or the air inlet and outlet, which is conducive to the hot air convection inside the studio.
3. The relationship between the choice of temperature range and the use temperature: There are three temperature ranges for the Yashilin brand electric blast drying oven: RT + 10 ~ 200 ℃, RT + 10 ~ 250 ℃, RT + 10 ~ 300 ℃. The appropriate temperature range can be selected according to the drying conditions of the items.
4. The normal heating rate of the electric blast drying oven is generally on average 2 ~ 8 ℃ / min. The temperature rises quickly at low temperature and slow at high temperature. The heating rate can be increased by increasing the heating power. However, as the heating power of the drying oven increases, the temperature overshoot at constant temperature also increases.
5. If you need to carry out multi-stage temperature rise, heat preservation control or enter and control the temperature rise rate, you need to choose a programmable temperature controller.
6. If the dried sample is humid and needs to be dried quickly, please specify when ordering, we will customize the rapid drying box for you.
7. The electric blast drying oven can be equipped with lead test holes (for energizing the samples or for leads). The diameter of the lead holes can be selected from 25, 50, 80 to 100mm.
