Dual-mode rapid detection system and method for moisture in dry powder for fruits and vegetables

Abstract

The invention relates to a dual-mode rapid detection system for moisture in dry powder for fruits and vegetables, which is characterized in that: a power supply is connected to a microwave dielectricoscillator; the microwave dielectric oscillator is connected to a microwave signal amplifier; a microwave signal amplifier is connected to a material room; one end of a microwave signal receiver is connected to the material room, and the other end is connected to a detector; the detector is connected to an operational amplifier; the operational amplifier is connected to a voltmeter; the voltmeteris connected to a control unit; a volume-weight instrument is mounted at the bottom of the material room; and the volume-weight instrument is connected to the control unit through a data line. The invention also relates to a dual-mode rapid detection method for moisture in dry powder for fruits and vegetables, which comprises the following steps: 1) performing pretreatment of the material; 2) adding fruit and vegetable powder; 3) collecting signals; 4) processing signals; and 5) completing the detection. The invention has scientific and reasonable design and adopts the dual-mode detection modeof microwave detection and bulk density detection to improve the accuracy of moisture detection, thereby ensuring long-term storage and quality of the fruit and vegetable powder.

Description

technical field [0001] The invention belongs to the technical field of drying, and relates to moisture detection of dried fruit and vegetable powder, in particular to a dual-mode quick detection system and method for moisture of dried fruit and vegetable powder. Background technique [0002] Fresh fruits and vegetables have high moisture content and are prone to rot and deterioration. After the fresh fruits and vegetables are dried and processed into vegetable powder, the water content is reduced, which can prolong the storage period and reduce storage, transportation, packaging and other costs. At the same time, as food accessories, dried fruit and vegetable powder can be added to infant food, dairy products, and baked foods to improve food flavor, color, and nutritional value, thereby increasing the added value of the product. Therefore, in the process of food processing, the application of fresh fruits and vegetables into fruit and vegetable powder is very extensive. ...
