Description

Electric heating naan pit and manufacturing method thereof

Technical Field

The invention relates to the field of barbecue equipment, in particular to an electric heating crusty pancake pit and a manufacturing method thereof.

Background

The naan is the most important food indispensable to the daily life of the masses in the Uygur family, and is also one of special foods in the Uygur family dietary culture. Uygur nationality has been eating naan for over 2000 years. The variety of the crusty pancake is many, and about more than 50.

The naan is generally baked in a naan pit made of saline-alkali soil (also mirabilite, sodium nitrate or sodium nitrate), a naan pit is dug in the wild in the production of Uygur people, the naan pit is made of Sinkiang saline-alkali soil, matches are burned into charcoal in the naan pit, the cooked pancake is pasted on the wall of the hot naan pit, and the naan pit is baked for a while, very crispy and delicious and good in flavor.

The crusty pancake has fragrant and crisp flavor because the crusty pancake is baked by being stuck to the wall of a saline-alkali crusty pancake pit with a fire at the bottom. According to local conditions, the materials for making crusty pancake are different for different nationalities and different regions, for example, for the Tajike in Pamier plateau, the crusty pancake is built by stones and the inside of the crusty pancake is pasted by soil. The Nang pit in northern Xinjiang is generally built by soil blocks or soil or bricks (baked bricks or soil bricks) and soil sand, but the Nang pit has no history of saline-alkali soil, and the baked Nang pit is not delicious and crisp. At present, most crusty pancake pits in cities are punched by steel plates, saline-alkali soil is not easy to find, and the crusty pancake pits are convenient to use and gradually become the mainstream of the city crusty pancake pits.

Along with the development of the society, in order to meet the requirement of no environmental pollution, a modern baking oven which uses electricity and gas for baking is produced in the aspect of heating, a heating wire is uniformly wound on the inner (or outer) side wall or the inner wall of a crusty pancake pit on electricity, or an electric heating rod is penetrated in the wall of the crusty pancake pit for supplying heat, the crusty pancake baked by the novel baking oven is baked under the condition of no fire and high temperature heat energy, no heat source is used for radiating the surface of the crusty pancake in the crusty pancake pit, the external surface of the crusty pancake cannot achieve the effects of golden yellow, bright and crisp, the bottom surface of the crusty pancake is not cooked uniformly, and the crusty pancake is just stuck to the corresponding part of the heating wire or the electric heating rod and is not cooked uniformly. When the heating wire is coiled on the crusty pancake pit wall or the electric heating rod is threaded in the crusty pancake pit wall, the temperature close to the heating wire or the electric heating rod is high, the temperature deviated from the heating wire or the electric heating rod is low, the temperature difference is large, saline-alkali soil is granular material, the heat transfer efficiency between molecules is poor, the temperature difference between adjacent particles is large, therefore, the saline-alkali soil crusty pancake pit in which the electric heating material is arranged next to the skin is not broken due to nonuniform heating in one month, the heating wire is easy to burn off, and the maintenance cost is increased invisibly. The gas stove is arranged at the bottom of the crusty pancake pit for heating by using gas, so that the temperature in the crusty pancake pit is higher, the crusty pancake pit is unsafe, the heat dissipation is uneven due to open fire, the outer surface and the bottom surface of the crusty pancake are unevenly heated, the bottom surface of the crusty pancake is not radiated by a heat source, and the effects of golden yellow, bright and crisp are not achieved. The salt-alkali soil crusty pancake pit which is bonded by electricity or gas is not firm, can be only manufactured in situ, can be used in situ and cannot be carried, and once the salt-alkali soil crusty pancake pit is carried, the wall of the salt-alkali soil crusty pancake pit is easy to break.
