The first-hand information that engineering design must master, the dishes set by users and the maximum number of diners are the main basis for plane layout design, and the main equipment, quantity and model can be determined accordingly. Users can supply energy sources, such as boiler steam, diesel oil, gas types, power supply (220V/380V), kitchen plane structure, size diagram and space height structure diagram. Basic user requirements: such as pipeline direction, sewage outlet, fan positioning, etc. Understand the investment situation of users from the side. Kitchen equipment layout heating equipment and quantity estimation: the first condition of kitchen layout is to meet the requirements of cooking technology, try to avoid the intersection of cold and hot, cleaning materials and dirt, and make each working area work nearby. Fully understand the kitchen space, plane topography, and the layout direction of heating equipment, and strive to make the smoke exhaust fresh air system less bent, short in distance and convenient to install.
