Abstract

The invention provides an online detection device and method for the physical property change of a fruit and vegetable drying process. The device consists of a stereoscopic visual detection apparatus,a dynamic weighing apparatus, a drying apparatus for drying treatment of materials, an electronic control unit and a computer. The stereoscopic visual detection apparatus is located above the dryingapparatus, and includes a light source box, and a left camera, a right camera, a camera fixed plate, adjusting units and strip light sources that are disposed in the light source box. The dynamic weighing apparatus includes a weighing sensor and two vertical support rods, the top ends of the support rods stretch into a drying chamber and are fixed to a pallet pedestal, and the bottom ends are in connection with the dynamic weighing sensor. The device and method provided by the invention can achieve online detection of the water content, shape, color and three-dimensional shape change of fruitsand vegetables under different drying processes, and provide theoretical guidance and detection basis for optimization of the hot air drying process.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to an on-line detection device and method for physical property changes in the drying process of fruits and vegetables. Background technique [0002] Dried fruit and vegetable products are increasingly becoming the best-selling food sought after by people. On the one hand, because its products can maintain the original appearance, flavor and nutritional content of fruits and vegetables to the greatest extent. On the other hand, the water content of fruits and vegetables is reduced after heating and drying, and the volume is greatly reduced, which can prolong the shelf life and facilitate storage and transportation. [0003] At present, the drying technologies commonly used for fruits and vegetables include hot air drying technology, vacuum freeze drying technology, variable temperature difference puffing drying technology, microwave vacuum drying technology,...
