AI Technical Summary
In existing technologies, the formation of a water film on the surface of temperature sensors in high humidity environments leads to overestimation of temperature readings, misjudging that the fresh food packets are not sufficiently cooled, causing disorder in the loading sequence, and increasing fuel and labor costs.
A programmable pulsed compressed air purging solenoid valve assembly is used to purify the surface of the temperature sensor probe with pulsed air to remove the high-temperature water film. The water film residue is judged by the variance of the rapid cooling temperature fluctuation. The maximum injection pressure and the highest blowing frequency are used for powerful blowing to ensure accurate temperature measurement.
This effectively avoids priority transportation rights caused by misjudgment of water film, prevents queue jumping during loading, reduces fuel and labor costs, and ensures food safety and transportation efficiency.
