Description

An energy-saving drying device for granular materials with a fan

technical field

The utility model belongs to the technical field of a drying device structure, in particular to the technical field of an energy-saving drying device for granular materials such as nuts and grains.

Background technique

When the existing granular materials such as nuts are being dried, they are poured into the drying chamber of the drying chamber at one time. The hot air chamber is located below the drying chamber, and the hot air blown by the hot air blower is introduced into the hot air chamber. The metal mesh in between dries the materials in the drying chamber, and the hot air flows upwards through the gaps between the granular materials to dry the materials. However, the height of the general drying chamber is 2.5~3m. At such a height, when the materials in the lower layer of the drying chamber have reached the drying standard, the materials in the middle and upper layers have not yet reached the drying standard, so the drying time should be prolonged or the hot air and wind force of drying should be increased. When the temperature is high, when the materials in the upper and middle layers reach the drying standard, the materials in the lower layer have already been over-dried, and they have cracked or broken, reducing or even losing their commodity value.

The beneficial effects of the utility model are:

1) Dry evenly, adopt the method of setting a ventilation pipe in the drying room and opening air holes on the ventilation pipe, so that the hot air can directly rise to the middle and upper parts of the drying room, so that the materials in the middle and upper parts can be dried by hot air function, so that the materials in the middle and upper parts can be dried to the same degree as the lower part; by changing the direction of the hot air, the materials can be heated evenly.

2) Energy saving, the utility model can utilize wind heat as much as possible, and make it possible to evenly heat the upper, middle and lower parts of the material at the same time, increasing the heating efficiency, the material does not move while the hot air moves, It avoids the huge energy consumption of traditional stirring method to make the material heated evenly, so it can greatly save energy.

3) After the material is dried, open the discharge port, relying on gravity, the material can be automatically discharged out of the bin.

4) The drying chamber can be equipped with an insulation layer according to the needs, which can further improve the utilization rate of heat energy and reduce energy consumption.

5) Increase the wind pressure, air supply volume, and uniform air supply: the use of fans can greatly increase the air supply volume, and the air supply can be uniform, which can shorten the drying time of materials.

Below with regard to accompanying drawing and specific embodiment, the utility model is further explained.
