Material temperature measuring system and method for continuous production type freeze-drying equipment

The invention discloses a material temperature measuring system for continuous production type freeze-drying equipment. The freeze-drying equipment comprises a freeze-drying bin and a drying heating device arranged in the freeze-drying bin, wherein the drying heating device is provided with a plurality of layers of stacked heating plates; the material temperature measuring system comprises a plurality of temperature measuring devices arranged on the heating plates of the drying heating device; each temperature measuring device comprises a temperature measuring element, a stroke rod and a hydraulic oil cylinder for controlling the temperature measuring element to stretch and retract inwards; and when materials move from a feeding end to a discharging end along the freeze-drying bin, the temperature measuring devices detect temperature parameters of each sublimation interface of the materials in real time. As the temperature measuring devices adopt telescopic contact type temperature measuring elements and are
