Red date drying dielectric property online detection device

Abstract

The invention discloses a red date drying dielectric property online detection device comprising a rack which is provided with a drying room and a control room. The rack is also provided with an air supply mechanism and an air exhaust pipe which are communicated with the drying room. The air supply mechanism is internally provided with a heating element. A control room is internally provided with an LCR digital bridge tester and an electric control unit. The support plate of the drying room is provided with a balance which is provided with a bracket with a tray. The tray is provided with a data acquisition device, a wireless transmitter, ventilation holes and a clamping mechanism. The clamping mechanism is provided with a dielectric test electrode connected with the data acquisition device. The data acquisition device is connected with the wireless transmitter. The LCR digital bridge tester, the heating element, the clamping mechanism and the wireless transmitter are connected with the electric control unit. The physical properties and the dielectric properties of the red date can be detected and monitored in real time online, and the detection result can be synchronously displayed so that operation is easy, use is convenient and the working efficiency is high; meanwhile, the red date does not need to be moved in the detection process so that the wholesomeness and the detection accuracy of the red date can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of fruit non-destructive testing equipment, in particular to an online testing device for the dried dielectric properties of red dates. Background technique [0002] At present, dielectric property testing is a non-destructive testing technology developed in recent years, which has important research value and great application potential in judging the ripeness and quality screening of fruits and vegetables. At this stage, there is no formed product on the dielectric characteristic testing platform. The dielectric characteristic testing for fruits and vegetables is based on the test system built in the laboratory. The test system includes the LCR bridge tester, which needs to be connected to a PC to perform Post data processing is not conducive to directly realize the detection of dielectric properties and the display of detection results on the embedded system. [0003] For example, the detection of the di...
