A drying device that can measure the color and shape changes of materials in real time

Abstract

The invention provides a drying device capable of measuring colors and form changes of materials in real time. The problems that an existing drying device cannot measure the colors and the form changes of the materials simultaneously and is lack of the capability of online testing can be solved. The drying device includes a material drying and weighing system, an air current circulation system, atemperature and humidity control system and a binocular stereo vision system, the material drying and weighing system includes an electronic scales, a material support which is arranged on the electronic scales and a material disc which is arranged on the material support, and the air current circulation system includes a centrifugal fan, a drying chamber and an air current circulation pipeline which communicates with the centrifugal fan and the drying chamber; and the binocular stereo vision system is arranged above the material drying and weighing system. According to the drying device capable of measuring the colors and the form changes of the materials in real time, the drying temperature, the air current speed, the air humidity and other drying parameters can be precisely controlled,and the online testing of the colors, the three-dimensional shapes and the moisture content of the materials in the drying process can be realized through the binocular stereo vision system and the material drying and weighing system.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a drying device capable of measuring the color and shape changes of materials in real time. Background technique [0002] Drying is an important part of agricultural product processing. During the drying process, in addition to the continuous reduction of the moisture content of the material, the color and shape of the material also change in real time. Color is one of the most important quality indicators of agricultural products. Consumers can immediately judge the quality of the product through the color of the product. The quality of the color directly determines the value of the product. The color change of the material during the drying process often indicates the occurrence of browning reaction, the degradation of heat-sensitive substances, and even the formation of some flavor substances. Therefore, the quality change of the material can be judged...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the present invention provides a drying device that can measure the color and shape changes of materials in real time to solve the problem that the existing drying devices cannot measure the color and shape changes of materials at the same time, and lack the ability of online detection. The device It can precisely control the drying parameters such as drying temperature, air velocity and air humidity, and realize the online detection of the color, three-dimensional shape and moisture content of the material during the drying process through the binocular stereo vision system and the material drying weighing system
