Energy-saving Chinese date drying bin

Abstract

The invention relates to an energy-saving Chinese date drying bin, belongs to the field of the agricultural product drying equipment, and particularly relates to drying equipment for drying stored and harvested Chinese dates of regions with arid climate and large temperature difference. The energy-saving Chinese date drying bin comprises support legs, a bin bottom plate, a bin gate, an external bin plate, a bin cover, a wind-proof cover plate, an internal bin plate, and an unpowered fan. Chinese dates are put in a cavity between the external bin plate and the internal bin plate. The pressure difference of the bottom outside the drying bin and the top part in the drying bin is generated by utilizing the stack effect and the assist of the unpowered fan, so that the air movement is formed. The air enters from a vent hole, and penetrates a Chinese date layer in the middle to take gasified moisture in the Chinese dates away, an air flow flowing upwards is concentrated and formed in an air channel chamber of the internal bin plate, and finally, the air flow is exhausted from the unpowered fan on the top, so that the aim of removing the moisture and drying the Chinese dates. According to the energy-saving Chinese date drying bin, the investment is low, and no operating cost is required. The energy-saving Chinese date drying bin adopts normal temperature air to dry the Chinese dates, so that the energy-saving Chinese date drying bin has the advantages of stability in keeping the quality of the Chinese dates, energy saving, labor saving, and reduction in environmental pollution. Moreover, the energy-saving Chinese date drying bin has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the field of drying equipment for agricultural products, and in particular relates to a drying equipment suitable for dry storage of harvested jujube in areas with dry climate and large temperature difference. Background technique [0002] Freshly harvested jujubes (water content 65%-70%) are stored at room temperature for a short time and are extremely perishable. Therefore, during the harvest season, jujubes urgently need to be dried after being picked to keep their moisture content below 25%. In the middle of the prior art, jujube is dried and usually adopts natural airing and two methods of artificial drying. Natural drying requires fine weather, choosing a suitable site, flipping during the day, collecting and covering at night, and paving the next morning. The workload is heavy and human resources are seriously wasted. And because the open air is aired for a long time, the surface dust accumulation of the dried jujube af...
