Description

Technical Field

[0001] The invention belongs to the technical field of cheese mixing and stirring, and particularly relates to a cheese mixing and stirring method and system. Background Art

[0002] In the cheese production process, stirring the curd mixture is a crucial step, and the stirring process will directly affect the texture, taste and quality of the final cheese product. The traditional cheese mixing and stirring method mainly relies on manual operation and simple mechanical equipment, which has many shortcomings. For example, when manually identifying the type, size and weight of the curd mixture, it is not only inefficient, but also difficult to achieve precise control, resulting in inaccurate feed amount, affecting the uniformity and quality stability of the cheese. In addition, the traditional stirring method can often only achieve stirring in a single direction, with limited stirring effect, and it is difficult to fully mix the curd.

[0003] At the same time, monitoring the solid-liquid separation effect and concentration during the mixing process is also a major problem. Traditional methods usually rely on manual observation and empirical judgment, lacking real-time and accuracy, resulting in the difficulty of achieving the ideal concentration and texture of cheese products. In addition, the clogging problem of the filter mechanism also occurs from time to time, which not only affects the mixing efficiency, but may also cause damage to the equipment.

[0004] In addition, the control of temperature, humidity and pH value during the cheese mixing process is crucial to the quality of cheese. The traditional method usually adopts the method of setting fixed temperature, humidity and pH value, but this method lacks the ability to automatically adjust according to real-time conditions, making it difficult to maintain consistent quality of cheese products.

[0005] With the development of intelligent and automated technologies, the cheese production industry has also begun to explore the application of new technologies in the cheese mixing process. However, the existing intelligent cheese mixing process still has some shortcomings, such as high energy consumption, imperfect remote monitoring and intelligent early warning functions.
