Abstract

The invention relates to an industrial cooking machine control system and method. The method comprises the following steps: acquiring a rice cooking temperature reference curve of different varieties of rice; monitoring the pot bottom heating temperature in real time, and determining the temperature error between the pot bottom heating temperature at each moment and the corresponding expected temperature, wherein the expected temperature is determined according to the rice cooking temperature reference curve; according to the temperature error, controlling the speed of transporting the cooking pot to the cooking machine module by the transmission device; and according to the temperature error, controlling the opening degree of a natural gas adjusting valve through a PID fuzzy control algorithm, so that closed-loop adjustment is conducted on the pot bottom heating temperature. Different rice cooking temperature reference curves are determined according to different rice varieties, closed-loop control over the pot bottom heating temperature is achieved by monitoring the pot bottom heating temperature and adjusting the opening degree of the natural gas automatic adjusting valve through an intelligent control algorithm, and efficient and energy-saving cooking control over the industrial cooking machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of industrial rice cooking, in particular to an industrial rice cooking machine control system and method. Background technique [0002] Large-scale rice processing equipment (industrial rice cooker) is represented by rice production line, mainly including rice washing machine, rice cooker, loosening machine and other related equipment. Its cooking capacity can reach 600kg / h. Due to its relatively large size, currently It is mainly used in large-scale unit canteens, hotels, restaurants and other catering establishments. Existing industrial rice cooking machines have the characteristics of automation, but on the one hand, the existing industrial rice cooking machines use fixed parameters to cook rice, failing to consider the cooking requirements of different varieties of rice, and the degree of intelligence is not high enough. It is difficult to meet the requirements of the taste, and only when experienced o...
