Description

Drying device

Technical Field

The invention relates to agricultural product processing equipment, in particular to a drying device.

Background

China is the country with the largest output of fruits, vegetables and the like in the world at present. The total yield of garden fruits exceeds 1.51 hundred million tons, and the total yield of vegetables is 7.08 hundred million tons. In addition to direct sale of fresh produce, the time period is long for north and south shipping problems, and produce can mildew and rot during shipping. Thus, many agricultural products need to be made into dry products for long term storage, transportation and processing. Common traditional Chinese medicinal materials, flue-cured tobaccos, oilseeds, tea leaves and the like are all required to be dried, but a single-layer drying mode is generally adopted at present, the occupied area of equipment is large, and the efficiency is low.

Disclosure of Invention

The technical problem that this application embodiment will solve provides a compact structure and area is little drying device.

The embodiment of the application is realized by the following technical scheme:

the utility model provides a drying device, includes multistage platform and hot air device, and multistage platform includes shell, base and a plurality of workstation that superposes each other, and the appearance chamber that is used for holding the workstation is established to the cover of shell separation outside the base, and the workstation setting of bottommost layer is on the base, and hot air device's export intercommunication bottommost workstation.

Further, drying device still includes the vibrator, and the vibrator setting is on the base.

Furthermore, the vibration exciting frequency F of the vibrator is 100-2000 Hz, and the vibration amplitude A is 0.01-0.05 mm.

Further, the vibration excitation frequency F of the vibrator changes with the time T in a sine manner, and the vibration amplitude A of the vibrator changes with the time T in a cosine manner.

Furthermore, the bottom surface of the workbench is a screen surface, and the diameter d of screen holes on the bottom surface is 0-2 mm.

Furthermore, the hot air device also comprises a plurality of hygrothermographs, wherein the hygrothermographs are arranged in the containing cavity, and the hygrothermographs are controlled and connected with the hot air device.

The beneficial effects are that:

compared with the prior art, the drying device is provided with the shell, the base and the plurality of the working tables, the shell is separately covered outside the base to form the containing cavity, the working tables are mutually overlapped, so that the drying space is utilized to the maximum extent, the occupied area is small, the working table at the bottommost layer is arranged on the base, the air outlet of the hot air device is communicated with the working table at the bottommost layer, hot air automatically rises, and the air outlet of each working table is not required to be arranged, so that the structure is compact.

Drawings

The following detailed description of embodiments of the present application is provided in conjunction with the appended drawings, wherein:

fig. 1 is a schematic structural diagram of a drying device according to the present invention.

Detailed Description

In order to make those skilled in the art better understand the technical solutions of the embodiments of the present application, the embodiments of the present application are described in detail below with reference to the drawings, and the description in this section is only exemplary and explanatory, and should not have any limiting effect on the scope of the embodiments of the present application.

As shown in fig. 1, a drying device comprises a multi-stage platform 1 and a hot air device 2, wherein the multi-stage platform 1 comprises a shell 11, a base 12 and a plurality of working tables 13, the shell 11 is separately covered outside the base 12 to form a containing cavity 14 for containing the working tables 13, the working tables 13 are mutually overlapped and placed in the containing cavity 14, a drying space is utilized to the maximum extent, the structure is compact, the occupied area is small, the working table 13 at the bottommost layer is arranged on the base 12 for realizing support, an air outlet 21 of the hot air device 2 is communicated with the working table 13 at the bottommost layer, hot air blown out by the hot air device 2 automatically rises and passes through each working table 13 to realize drying of agricultural products such as tea leaves, traditional Chinese medicinal materials, flue-cured tobacco and oilseeds, and the like, and hot air does not need to be provided with a hot air inlet and outlet at each working table 13, the structure is compact, and, Secondary drying of agricultural products such as traditional Chinese medicinal materials, flue-cured tobacco and oilseeds is carried out, and finally hot air is blown out from a joint of the shell 11 and the base 12, so that the drying process of the agricultural products is realized.

In a preferred embodiment, as shown in fig. 1, the drying device further includes a vibrator 3, the vibrator 3 is disposed on the base 12, and the vibration of the vibrator 3 is transmitted to each work table 13 through the base 12, so that the agricultural product drying effect is good. According to actual requirements, the excitation frequency F of the vibrator 3 can be set to be 100-2000 Hz, the vibration amplitude A is 0.01-0.05 mm, and the agricultural products are not damaged due to violent vibration; in specific implementation, the vibration excitation frequency F of the vibrator 3 changes with the sine of time T, and the vibration amplitude a of the vibrator 3 changes with the cosine of time T, so as to ensure the uniformity of vibration and ensure that agricultural products can be dried.

In a preferred embodiment, as shown in fig. 1, the bottom surface 131 of the working table 13 is a sieve surface, and the diameter d of the sieve holes of the bottom surface 131 is 0-2 mm, so that the hot air can smoothly enter each working table 13, and the agricultural products in the previous working table 13 can not be mixed into the next working table 13.
