Li Ziqi bread kiln principle

The principle of Li Ziqi Bread Kiln is to bake food by radiant heat of kiln body insulation. Li's bread kiln is a kind of earthen kiln, with simple manufacturing process, good cooking effect and long key heat preservation time. Li's bread kiln is divided into thermal insulation layer, thermal insulation layer and structural layer, which takes a long time from design, manufacture to completion.

The insulation layer of Li Ziqi bread kiln is composed of soil and sand. Soil can be selected from loess at home, but loess also needs to be tested to know the proportion of sand. There should not be too much sand, otherwise the kiln shape is unstable, and there should not be too little sand, otherwise the soil is too sticky and the kiln will crack.

The insulation layer is an empty glass bottle, and the glass bottle and stone play the role of reducing heat loss and insulation. The structural layer consists of soil, sand and straw. The mixing of straw with soil and sand can increase the toughness of the kiln itself, and the air brought by straw will not crack the kiln itself. The shape of the bread kiln can be used freely. After the overall shape of the bread kiln is successfully made, it needs to be dried naturally, then the kiln is opened and then set on fire. After a long period of use, the food made by the bread kiln is more delicious.
