2. Heating uniformity. Ignite the Buffy furnace and check whether the temperature in each position in the furnace is uniform. The temperature difference between the center position and the edge position should be within 30 C. Uneven temperature distribution will affect the cooking effect.
3. Fire layer effect. Put some boards around the hearth of Buffy furnace, and check whether the boards are in good condition after 30 minutes of ignition. Check whether the thermal insulation layer and insulation layer of Buffy furnace have played a good role in fire prevention.
4. Smoke exhaust effect. After the Buffy furnace is ignited, check whether the exhaust pipe is unobstructed and whether the flue gas is unobstructed. Smooth smoke exhaust is one of the important measures for kitchen safety and fire prevention.
5. Temperature holding time. Heat 300ml of water to 60°C, then turn off the power supply of Buffy furnace, and check whether the water temperature is kept above 55°C after 4 hours. Check the thermal insulation capacity of Buffy furnace, which can continuously provide energy for the cooking process.
6, easy to clean. Check whether the internal structure of Buffy furnace is flat and smooth, and whether there are any gaps in it. Smooth and flat cooktops are easy to clean, which is also one of the requirements of hotels for kitchen equipment.
