Embodiment 1

[0017] Example 1, such as figure 1 Shown is an electric heating two-stage Polygonatum odoratum dryer of the present invention, including a power supply 11, a control device connected to the power supply 11 through an electric wire 10, a heating device connected to the control device, and a heating device connected to the heating device. Drying unit connected to the unit.

[0018] The drying device includes a heat exchange chamber 1, a drying chamber 4 located above the heat exchange chamber 1, a secondary drying chamber 15 connected to the drying chamber 4 through a heat conduction channel 14, and a secondary drying chamber 15 located in the drying chamber. 4 and the conveyor belt 5 in the secondary drying chamber 15.

[0019] An air inlet is arranged at the bottom of the heat exchange chamber 1, and an inlet switch cover is arranged on the air inlet. A partition 2 is arranged between the heat exchange chamber 1 and the drying chamber 4, and rectangularly arranged pores are ...

Embodiment 2

[0025] Embodiment 2, embodiment 2 is different from embodiment 1 in that the area of ​​the pores on the partition 2 accounts for 80% of the entire partition 2 area, and on the basis of embodiment 1, in the secondary drying chamber 15 An outer conveyor belt is arranged between the discharge port 3 and the feed port 6 of the drying chamber 4, and the outer conveyor belt transfers the materials coming out of the secondary drying chamber 15 to the drying chamber 4 for drying again. The transmission speed of the conveyor belt 5 in the secondary drying chamber 15 is the same as that of the conveyor belt 5 in the drying chamber 4 .

[0026] The application method of the present invention: when starting to work, turn on the power supply 1, the resistance wire 12 starts to heat, and at the same time, the inlet switch cover located at the lower part of the heat exchange chamber is opened. When the heating wire heats the surrounding air, the heated air rises and new cool air is added. T...

Abstract

The invention discloses an electric heating two-stage polygonatum odoratum drying machine and an application method thereof. The electric heating two-stage polygonatum odoratum drying machine comprises a power supply, a control device connected with the power supply, a heat supplying device connected with the control device and a drying device connected with the heat supplying device, wherein the drying device comprises a heat exchange chamber, a drying chamber arranged above the heat exchange chamber, a secondary drying chamber connected with the drying chamber through a heat conducting channel and a conveyor belt arranged in the drying chamber; a separating plate is arranged between the heat exchange chamber and the drying chamber, air holes are formed in the separating plate, the drying chamber is communicated with outside through the air holes, and the conveyor belt is connected with a feeding hole and a discharging hole. The electric heating two-stage polygonatum odoratum drying machine has the advantages that heat energy provided by a heating unit is fully utilized, and polygonatum odoratum is subjected to two-stage drying; meanwhile, intelligent control equipment is adopted, so that quality of the dried polygonatum odoratum is improved and stabilized, and labour intensity of an operator is reduced.

Description

technical field [0001] The invention relates to a drying device, in particular to an electrically heated two-stage Polygonatum odoratum dryer and an application method thereof. Background technique [0002] In the drying process of walnuts, chestnuts and other Polygonatum odoratum, it usually needs to be dried more than twice to make the walnuts, chestnuts and other Polygonatum odoratum meet the quality requirements. Existing Polygonatum odoratum drying machine directly uses heating device to heat air, then dries Polygonatum odoratum with heated hot air. During the heating process, the waste heat is directly discharged out of the equipment, which is not fully utilized, and the waste of resources is serious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electrically heated two-stage Polygonatum odoratum dryer, which can make full use of the heat energy provided by the heating device to perform secondary dr...
