Intelligent microwave continuous drier and control method thereof

Abstract

The invention discloses an intellectualized microwave continuous drier and a control method thereof; the drier comprises a rack, a conveying belt, a conveying belt wheel, a driving motor, an instrument control box and a computer; two ends of the conveying belt are respectively provided with a feed hopper and a discharge hopper and the conveying belt runs through a plurality of microwave drying cavities with doors; each microwave drying cavity is internally provided with a microwave magnetron, a temperature sensor, a humidity sensor and a speed-regulating fan; the feed hopper and the discharge hopper are respectively provided with a moisture sensor, and the conveying belt is driven by a speed-regulating motor controlled by a frequency converter. A control system can automatically draw variation curves of the temperature and the humidity of the materials in each drying cavity and the water content ratio of the discharged materials in the drying process of the materials in shorter time according to the collected data of the temperature, the humidity and the water content ratio of the materials in the drying process of the materials, can optimize control parameters continuously according to the change of the temperature, the humidity and the water content ratio in the drying process of the materials, and can regulate the system parameters automatically and realize the dynamic optimization of the drying technique parameters.

Description

technical field [0001] The invention relates to a microwave dryer for processing agricultural by-products, in particular to an intelligent microwave continuous dryer and a control method thereof. Background technique [0002] If the agricultural by-products such as Chinese herbal medicines, tea leaves, grains, fruits and vegetables cannot be dehydrated in time after harvest, they will rot and deteriorate, which will reduce the quality and affect storage and normal use. At present, microwave drying technology has been widely used in the dehydration processing of grain, fruits and vegetables, Chinese herbal medicine, tea, etc., but the degree of automation of the drying device is low, the operation is inconvenient, the statistical analysis of data is cumbersome, and the efficiency is low. Develop an intelligent microwave continuous dryer, which can detect the temperature, material moisture content, drying rate and humidity in the drying chamber in real time during the drying p...
