Drainage dry air dryer

Abstract

The invention relates to a drainage type drying air drying device, which comprises a drying box and a drying air generator, and a drying object pallet with a hot air outlet is arranged inside the drying box. The hot and humid air cooling box and the heat exchange box are arranged side by side in the dry air generator, and the lower part of the hot and humid air cooling box and the heat exchange box are provided with cold air pipes respectively connected to the bottom of the hot and humid air cooling box and the heat exchange box . One end of the hot and humid air pipe is connected to the upper end of the hot and humid air cooling box, and the other end of the hot and humid air pipe penetrates into the upper end of the drying box. One end of a dry air pipe is connected to the upper end of the heat exchange box, the other end of the dry air pipe penetrates into the bottom end of the dry box, and a drain pipe is connected to the lower end of the hot and humid air cooling box. The invention has the characteristics of continuous supply of dry and constant temperature air, fast drying speed, remarkable energy-saving effect, free adjustment of temperature and humidity, simple structure, and convenient use.

Description

technical field [0001] The invention relates to a drying device, especially a drainage type drying air drying device, which is suitable for drying various items, and is especially suitable for making seed specimens, wax leaf specimens, medicinal material specimens and the like during the general survey of plant resources. Background technique [0002] At present, drying devices such as drying ovens and blast drying ovens often use the small ambient temperature difference of the drying oven, that is, the difference in water dissolution in the air generated by the heating of the drying oven to absorb the moisture of the drying body and discharge the moisture through small louvers. To the outside of the small environment, and then add air from outside the small environment for heating, so as to dry the items to be dried. When using this method, the drying speed of the item depends on the temperature inside the drying box and the humidity of the environment outside the drying bo...

AI Technical Summary

Problems solved by technology

When using this method, the drying speed of the item depends on the temperature inside the drying box and the humidity of the environment outside the drying box, that is, when the temperature inside the drying box is relatively high and the external environment of the drying box is relatively dry, the drying effect of the item will It will be more ideal; when the temperature inside the drying box is relatively low and the external environment of the drying box is relatively humid, the drying effect of the items is not ideal, and it may even cause some items to become moldy and rot before the drying is over.

Especially for seeds and medicinal materials, the inability to obtain ideal drying and shade-drying effects has become a bottleneck that is difficult to guarantee their quality.
