Description

TECHNICAL FIELD

[0001] The utility model relates to microwave drying machine technical field especially relates to a large -scale rice microwave drying machine. BACKGROUND

[0002] Rice needs to be dried after harvesting to reduce the moisture content and facilitate storage. Traditional drying methods, such as flame, hot air, steam, and electric heating, are all external heating drying methods. After the material surface absorbs heat, heat is transmitted and penetrates to the inside of the material, and then the temperature rises and dries. In traditional drying processes, to increase the drying speed, the external temperature needs to be raised and the temperature difference gradient needs to be increased. However, this easily causes the phenomenon of material surface scorching and inside drying. Therefore, the traditional heating drying method has a small application range. In addition, the traditional heating drying method has low thermal efficiency, resulting in low energy conversion rate and serious energy consumption waste. Microwave drying is completely different. During drying, microwave energy directly acts on the medium molecules to convert into heat energy. Since microwaves have penetrating properties, the inside and outside of the medium are heated simultaneously, and heat conduction is not required. Therefore, the heating speed is very fast. For rice with a water content of less than 30%, the drying speed can be shortened by hundreds of times. At the same time, regardless of the shape of the object, since the inside and outside of the object are heated simultaneously, the temperature difference between the inside and outside of the material is small, and the heating is uniform. This method does not produce the scorching outside and drying inside phenomenon that occurs in conventional heating, greatly improving the drying quality.

[0003] However, the existing large-scale rice microwave drying machine is prone to accumulate rice at the feeding port during actual use, causing the feeding port to be blocked and making it inconvenient to improve the feeding speed. UTILITY MODEL CONTENTS
