Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature detection, and in particular to an infrared temperature sensing device for food electron accelerator irradiation. Background Technology
[0002] With social development, the application of food electron accelerator irradiation technology in food processing is becoming more and more widespread. Especially for frozen foods, accurate temperature detection is the key to ensuring irradiation quality. Frozen foods have strict requirements for temperature rise during the irradiation process. Excessive irradiation time may cause product temperature loss, affecting quality and even causing safety problems. Therefore, it is necessary to trace and automatically control the irradiation temperature of products in real time.
[0003] However, existing detection methods mainly rely on manual use of traditional infrared detectors. These devices require fixed single-point detection and cannot perform full-coverage temperature monitoring of continuously moving materials on the conveyor belt. They are prone to missing temperature anomalies, which can lead to some materials losing temperature or uneven irradiation due to improper temperature control, affecting product quality stability. At the same time, manual operation is inefficient and cannot meet the real-time monitoring needs of large-scale production. Utility Model Content
