[0002] Medicinal materials refer to raw materials derived from plants, animals or minerals and used for the treatment, prevention and diagnosis of diseases. After corresponding processing, medicinal materials can be made into drugs. For example, traditional Chinese medicine (TCM) medicinal materials are raw materials used in TCM for the prevention, treatment and diagnosis of diseases, mainly derived from natural plants, animals and minerals. TCM medicinal materials have a long history and unique treatment theories and are widely used in TCM clinical practice.

[0003] A microwave tunnel for drying medicinal materials is a device for drying TCM medicinal materials. It combines microwave heating technology and a tunnel-type transmission structure and can efficiently and evenly dry TCM medicinal materials.

[0004] The structure of the microwave tunnel for drying medicinal materials in the prior art, for example, the tunnel-type microwave drying equipment with high safety factor disclosed in Chinese Patent No. 201721218092.6, has a blocking mechanism slidably arranged in its microwave heating chamber. The blocking mechanism is fixedly connected to a telescopic cylinder used to control the jitter and blanking of the blocking mechanism, which can prevent medicinal materials from sticking to the inner wall of the microwave heating chamber. However, the above equipment still has the following deficiencies: due to the large length of the tunnel structure, the installation of the filter screen of its blocking mechanism is difficult, which reduces the installation and commissioning efficiency. At the same time, due to the lack of moisture exhaust measures, moisture may accumulate and affect the drying effect.

[0025] According to an embodiment of the present utility model, a microwave tunnel for drying medicinal materials is provided.

[0026] Now, the present utility model will be further described in combination with the drawings and specific implementation manners. As Figures 1-5 shown, the microwave tunnel for drying medicinal materials according to an embodiment of the present utility model includes a support 1. A microwave heating box 2 is provided at the top end of the support 1. A plurality of observation windows 3 are provided on the side wall of the microwave heating box 2.

[0027] Among them, microwave heating is a heating method that utilizes the heat energy generated when electromagnetic waves propagate in a substance. It causes polar molecules (such as water molecules) in the substance to vibrate rapidly in the microwave field, generating frictional heat, thereby raising the temperature of the substance itself. After the microwave energy is generated by a microwave generator (such as a magnetron) in the microwave heating chamber 2, it is transmitted into the microwave heating chamber 2 and comes into contact with the medicinal materials. The microwave penetrates the medicinal materials, causing the water molecules inside and on the surface to vibrate and generate heat energy, quickly heating the medicinal materials.

[0028] With the above solution, the utility model can perform microwave drying on traditional Chinese medicine medicinal materials, improve the installation and debugging efficiency of the filter screen body 505, reduce the risk of medicinal materials sticking, and through the efficient and uniform dehumidification mechanism 6, timely discharge the moisture generated during the drying process, improving the drying effect.

[0029] In one embodiment, for the above-mentioned separable filter screen mechanism 5, the separable filter screen mechanism 5 includes fixing blocks 501 arranged inside the microwave heating chamber 2 and on both sides of the conveyor 4. A T-shaped groove 502 is provided inside the fixing block 501, and a T-shaped slider 503 is arranged inside the T-shaped groove 502. A frame 504 is arranged between the tops of the two T-shaped sliders 503, and a filter screen body 505 is arranged inside the frame 504; connection blocks 506 are arranged at both ends of the fixing block 501, an installation plate 507 is arranged at the end of the connection block 506 away from the fixing block 501, a first bolt 508 is screwed inside the installation plate 507, and a rubber baffle 509 is arranged between the first bolt 508 and the T-shaped slider 503; a number of threaded holes 510 are arranged at one end of the fixing block 501 close to the connection block 506, a number of second bolts 511 are arranged inside the connection block 506, and the threaded ends of the second bolts 511 are connected to the threaded holes 510, so that the length of a single filter screen body 505 becomes smaller, the installation of the filter screen body 505 is more convenient, the filter screen body 505 effectively prevents the medicinal materials from sticking to the inner wall of the microwave heating chamber 2, improving the drying efficiency and product quality; and the filter screen bodies 505 are fixed at both ends of a number of filter screen bodies 505 to prevent the filter screen bodies 505 from shifting during use.

[0030] The working principle of the separable filter screen mechanism 5 is as follows: Each filter screen body 505 is connected inside the frame 504, the bottom of the frame 504 is connected to the T-shaped groove 502 through the T-shaped slider 503, and a number of filter screen bodies 505 are arranged end to end in the microwave heating chamber 2; the first bolts 508 arranged at both ends of the fixing block 501 abut against the side wall of the T-shaped slider 503 at the end of the T-shaped slider 503 through the rubber baffle 509, so that a number of filter screen bodies 505 are kept stable and will not slide.

[0031] In one embodiment, for the above-mentioned dehumidification mechanism 6, the dehumidification mechanism 6 includes a plurality of first dehumidification blowers 601 arranged at the top of the microwave heating chamber 2, and a top moisture exhaust pipe 602 is arranged at the top of the first dehumidification blower 601; a plurality of side moisture exhaust pipes 603 are arranged on the side wall of the top moisture exhaust pipe 602, and a second dehumidification blower 604 is arranged in the side moisture exhaust pipe 603, so as to quickly and effectively discharge moisture and maintain a dry environment. The design of the top moisture exhaust pipe 602 and the side moisture exhaust pipes 603 improves the dehumidification efficiency and reliability.

[0032] The working principle of the dehumidification mechanism 6 is as follows: The first dehumidification blower 601 and the second dehumidification blower 604 are started through an externally provided control panel, and moisture begins to be discharged from the top of the microwave heating chamber 2 and enters the top moisture exhaust pipe 602. The top moisture exhaust pipe 602 directly discharges a part of the moisture, and guides the other part to each side moisture exhaust pipe 603, and is further discharged by the second dehumidification blower 604.

[0033] Among them, the first dehumidification blower 601 and the second dehumidification blower 604 discharge the wet air from the microwave heating chamber 2 through forced ventilation, preventing moisture from accumulating in the microwave heating chamber 2 and maintaining a dry environment.

[0034] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0035] In actual application, traditional Chinese medicine materials are continuously conveyed into the microwave heating chamber 2 by a conveyor 4. The materials are dried by the microwave heating chamber 2. A plurality of filter mesh bodies 505 can prevent the materials from sticking to the three-dimensional inner wall of the microwave heating chamber 2. The materials in the microwave heating chamber 2 are quickly heated by microwave energy, and the internal moisture evaporates. The moisture generated during the microwave heating process is quickly discharged through the dehumidification mechanism 6. The operator can monitor the drying process of the materials in real time through the observation window 3 on the side wall of the microwave heating chamber 2.

[0036] In summary, the present invention can perform microwave drying on traditional Chinese medicine materials, improve the installation and debugging efficiency of the filter mesh body 505, reduce the risk of material adhesion, and timely discharge the moisture generated during the drying process through an efficient and uniform dehumidification mechanism 6, improving the drying effect.
