Precautions when using hot air circulation oven:
1. The hot air circulation oven should be placed at a clean indoor level. Keep it dry, prevent moisture and moisture, and prevent corrosion. Hot air circulation oven working temperature: room temperature +10--300 °C, any temperature can be set, temperature uniformity: plus or minus 1.5%.
2, there must be a certain space for the hot air circulation oven to be placed, and there should be a certain distance from the wall on all four sides. It is recommended to have more than 2 meters. Hot air circulation oven duct: double air duct, horizontal or vertical circulation. Shell material: Q235 carbon steel cold-rolled sheet metal plate bending welding rivet splicing. Hot air circulation oven liner and duct system material: brushed stainless steel plate sheet metal bending machine punching
3, hot air circulation oven check voltage before use, the smaller hot air circulation oven required voltage is 220V, the larger to hot air circulation oven required voltage is 380V (three-phase four-wire), according to the hot air circulation oven power consumption installed enough Capacity power knife. And choose the right power cable. Also work on the grounding wire. Hot air circulation oven safety protection: leakage protection, open circuit protection, motor overload protection, grounding protection
4. After the above work is ready, the sample can be placed in the hot air circulation oven, then connected to the power supply, the hot air circulation oven switch, the hot air circulation oven with the air blowing device, and the blower must be turned on during heating and constant temperature. Otherwise, the temperature of the studio is uniform and the heating element may be damaged. Then adjust the temperature of the suitable test products, and the hot air circulation oven will enter the working state.
5, the baked goods can not be arranged too densely, the hot air circulation oven bottom (heat sink) can not put items, so as not to affect the hot air circulation, prohibiting the burning of flammable, explosive items and volatile and corrosive items. Hot air circulation oven heater: Far-infrared dust-free stainless steel tubular electric heater with continuous service life of 50,000-60,000 hours.
6. After the baking is finished, cut off the power supply before opening the studio door. Remember not to touch the baked items directly with the hand. Use special tools or insulated gloves to take the baked items to avoid burns.
7. The hot air circulation oven should be kept clean in the working room.
8. When using a hot air circulation oven, the temperature should not exceed the high temperature of the hot air circulation oven, and the general hot air circulation oven is below 250 degrees. Hot air circulation oven constant temperature timing: 0.01--99.99 hours, time to cut off heating, buzzer prompt
