Abstract: A bake system comprises a baking unit for supporting object to be baked, and heating the object to be baked; a weight sensor for measuring weight of the object to be baked on the baking unit; the measurement being continuously performed in the baking process and outputting measuring values; and an operation unit receiving predetermined number of data from the converting unit and averaging the data continuously received from the converting unit for reduction of errors. The bake system detects the baking levels of the object to be baked by detection of the variations of the baking object in the baking proves. Therefore in the baking process, the heating temperature, time periods and other factors are controlled for getting final products with desired baking levels.
