[0028] A vacuum tube 24 is provided on the feed shaft 22 for vacuuming the conical drum 1. The vacuum tube 24 is provided at the end of the feed shaft 22 because more air is taken in at the feed tube 221 due to the feeding. The vacuum tube 24 is provided here to improve the vacuuming efficiency.

[0029] The feed pipe 221 is passed through the feed shaft 22, and the discharge pipe 321 is passed through the discharge sealing sleeve 3. Electromagnetic valve control switches can be set on the feed pipe 221 and the discharge pipe 321 to ensure the vacuum degree in the conical roller 1 when there is no need to feed or discharge; the feed pipe 221 is connected to the feed bin, and the feed bin can be fed by vibration feeding; the discharge pipe 321 is connected to the finished product bin, and because the finished product bin is communicated with the conical roller 1, the air in the finished product bin 1 can be extracted in advance to make it reach a vacuum state.

[0030] In one embodiment of the present application, preferably, Figures 1 to 5 As shown, tracks are provided on the side walls of the feed cylinder 12 and the discharge cylinder 13 , and the tracks are divided into a feed track 121 and a discharge track 131 , and the tracks are respectively mounted on supporting bearings provided on the feed base 4 and the discharge sealing sleeve 3 .

The gear ring 122 is provided on the feed cylinder 12. On the one hand, the diameter of the gear ring 122 is maximized to reduce the speed of rotation; on the other hand, a discharge sealing sleeve 3 is provided on the discharge cylinder 13.

[0032] In one embodiment of the present application, preferably, Figure 2 , Figure 3 As shown, a plurality of discharge holes 103 are provided on the side wall of the discharge cylinder 13, and the discharge holes 103 are arranged in a ring array on the side wall of the discharge cylinder 13. The discharge sealing sleeve 3 is sleeved on the outer wall of the discharge cylinder 13 and seals the discharge holes 103. When the conical drum 1 rotates, the discharge pipe 321 is always connected to one or two discharge holes 103. The discharge track 131 is arranged on the inner side of the cone barrel 11 closer to the discharge holes 103, so as to provide better support.

[0033] In one embodiment of the present application, preferably, the inner wall of the conical drum 1 is provided with a coating for reflecting microwaves, which can improve the microwave reflection efficiency in the conical drum 1 to improve the drying efficiency.

[0034] In one embodiment of the present application, preferably, Figures 1 to 5 As shown, a liquid cooling pipe 25 is also provided on the shaft bracket 2. The liquid cooling pipe 25 is passed through the feed shaft 22 and / or the discharge shaft 23. The liquid cooling pipe 25 dissipates heat for the microwave emitting assembly 211. One or more liquid cooling pipes 25 may be provided. The liquid inlet end and the liquid outlet end of the liquid cooling pipe 25 may be selectively passed through the feed shaft 22 and / or the discharge shaft 23.

[0038] According to the raw material drying device for processing vegetable seasoning packets of the utility model, when the conical drum 1 rotates, the shaft support 2 coincident with the axis thereof does not rotate, so the feed shaft 22 and the discharge shaft 23 at both ends of the shaft support 2 can be penetrated by a feed pipe 221, a vacuum tube 24, a cold liquid tube 25 and a wiring harness of a microwave emitting assembly 211, etc.; in order to ensure the sealing inside the conical drum 1, a discharge sealing sleeve 3 is provided at the discharge end, so that the conical drum 1 is not connected to the outside atmosphere and the vacuuming efficiency is reduced; the drum is set to be conical, so that the material at the feed end can be transported at a longer distance, and the utilization rate of microwaves can be improved; because there is a higher vacuum degree inside the conical drum 1, the boiling point of water is lower, and the water vaporizes very quickly, but the vacuum degree has no significant effect on the microwave, so the drying efficiency is higher.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
