The annual Christmas is almost there, and we've recently seen a lot of sweets on Christmas topics. It's a simple cake and it's Christmas. Let's do it together. It's gonna be a nice kaoker 1 smart oven. It is distributed by two high-precision temperature sensors to angular lines and achieves a precise temperature perception by blurring control algorithms. Three electro-thermal tubes achieve an infinity correction through the PID algorithm, are hotter and smoother. The internal temperature is very even. 25-45 °C, temperature deviation ± 1 °C; 150-230 °C, temperature deviation ± 3 °C even, multi-layer roast without pressure! The total temperature covers 25~230°C, fermentation, defrozen, dried fruit, baking, air blowing, barbeque, excellent。
