Disc type recirculating air drying device and method

Abstract

The invention relates to the technical field of agriculture, in particular to a disc type recirculating air drying device and method applied to fruit such as apricot, walnut and red dates. The disc type recirculating air drying device is mainly composed of a coal hot air furnace, a heat insulation board, an air duct, a drying chamber, a moisture exhaust fan, a first circulating fan, a second circulating fan, a warm air chamber, a hot-blast stove, an electronic overturning plate a, an electronic overturning plate b, a horn mouth and a parallel stream diversion device. When the device works, the temperature and moisture of the interior of the drying chamber are monitored in real time through a temperature and moisture detection device, the current temperature and moisture are judged according to set temperature bounds, real-time change of heated air circulation methods is conducted according to a set drying technology, the drying effect that air circulation is achieved and disc dumping is avoided is realized, and fruit is collected and packaged or loaded to be stored or sold after the moisture content of the fruit meets the requirements.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a disc-type circulating air drying equipment and method for fruits such as apricots, walnuts, and jujubes. technical background [0002] At present, fruit planting is basically still in the state of small-scale self-employed farmers and extensive management of orchards. In order to harvest and sell as soon as possible, farmers often pick at one time, and they cannot be picked strictly according to the ripening time, and the maturity varies; the drying of the fruit is average. The natural drying method is used, which delays the time for the product to go on the market. During the natural drying process, it often encounters cloudy and rainy weather, and the fruit is easy to mold, grow hair, darken the color, and the product grade will decline. At present, the fruit drying room on the market can avoid the influence of the weather, but there is a phenomenon of uneven drying. In...

Problems solved by technology

[0002] At present, fruit planting is basically still in the state of small-scale self-employed farmers and extensive management of orchards. In order to harvest and sell as soon as possible, farmers often pick at one time, and they cannot be picked strictly according to the ripening time, and the maturity varies; the drying of the fruit is average. It adopts the natural drying method, which delays the time for the product to go on the market. During the natural drying process, it often encounters cloudy and rainy weather, and the fruit is easy to mold, grow hair, darken the color, and the product grade declines.

At present, the fruit drying room on the market can avoid the influence of the weather, but there is a phenomenon of uneven drying. In order to solve these problems, a disc-type circulating air drying equipment and method have been developed, which can ensure uniform drying and solve the problem of manual drying. Turnaround is labor-intensive and time-consuming
