Description

Technical Field

[0001] This utility model belongs to the field of microwave drying technology, specifically relating to a microwave drying device that can uniformly dry products. Background Technology

[0002] Microwave heating is a type of radiative heating where microwaves act directly on an object, heating it both inside and out simultaneously. It does not require heat transfer through convection or conduction, resulting in rapid heating, high thermal efficiency, short processing time, and uniform temperature throughout the material. Consequently, it saves energy, achieves high drying efficiency, and produces high-quality drying.

[0003] Current microwave drying equipment typically places solid products on a rotating tray inside the equipment. However, because the solid products are in contact with the tray, the area where they are in contact is obstructed, resulting in inconsistent drying effects between this area and the exposed areas. This leads to uneven drying of the moisture within the solid products. Furthermore, the solid products placed on the tray may move on their surface during the drying process, potentially colliding with the equipment's interior and hindering safe drying. Therefore, a microwave drying device capable of uniform drying is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a microwave drying device that can uniformly dry food, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a microwave drying device capable of uniform drying, comprising a drying chamber, a driving assembly, a microwave generating assembly, two waveguides, a conducting assembly, several fixing assemblies, and a supporting assembly, wherein the drying chamber comprises a chamber body;

[0006] The drive assembly includes a motor connected to the housing, the output shaft of the motor being connected to a drive gear, the drive gear meshing with a driven gear, and a first turntable connected inside the driven gear;

[0007] The microwave generating assembly includes a microwave transmitter body and a fixed plate. Several first pipes are opened in the surface of the fixed plate, two of which are connected to microwave transmitting tubes, two microwave transmitting tubes are connected to the housing, and the other two second pipes are connected to waveguides.

[0008] The conductive component includes a second turntable, a plurality of second pipes are opened inside the second turntable, a first bearing is connected inside the second turntable, and second bearings are connected to the outside of both the first and second turntables. The first bearing is connected to the outside of the waveguide, and the second bearing is connected to the inside of the housing.

[0009] The fixing component includes a first metal tube connected to the bottom of the second turntable, a second metal tube slidably connected inside the first metal tube, the first metal tube being connected to the top end of the second metal tube by a spring, the spring being located inside the first metal tube, the bottom ends of several first metal tubes being connected to a first plastic cap, and several second metal tubes being connected to the same pull plate.

[0010] The support assembly includes a third metal tube, several third metal tubes are connected to the upper surface of the first turntable, and the top ends of the several third metal tubes are connected to a second plastic cap. Several third pipes are opened inside the first turntable.

[0011] As a preferred embodiment, the chamber is provided with a first isolation chamber, two second isolation chambers and a drying chamber, and the front of the chamber is provided with an operation panel.

[0012] As a preferred embodiment, the front of the housing is rotatably connected to a baffle, and the baffle has an observation window inside.

[0013] As a preferred embodiment, the main body of the microwave transmitter is connected within the first isolation cavity, and both waveguides are connected within the second isolation cavity.

[0014] As a preferred embodiment, the emission port of the microwave transmitter body is connected to several first pipes, two of which are connected to microwave emission tubes and the other two are connected to waveguides.

[0015] As a preferred embodiment, the waveguide located above is connected to several second pipes, which are arranged in a circular array and are shaped as an inclination.

[0016] As a preferred embodiment, the second pipe is connected to the first metal pipe, and the first metal pipe is connected to the second metal pipe.

[0017] As a preferred embodiment, the waveguide located below is connected to several third pipes, which are connected to third metal pipes. The several third metal pipes are arranged in a circumferential array, and the shape of the third pipes is set to be inclined.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention controls the operation of the main body of the microwave transmitter. Microwaves are emitted into the drying chamber through two horizontal microwave transmitting tubes. Microwaves entering the second pipe move through the first metal tube into the second metal tube, and then through the first plastic cap into the solid product. Simultaneously, microwaves entering the third pipe move through the second plastic cap into the solid product. This allows the solid product to be dried from multiple directions using only one microwave transmitter, reducing drying costs. Furthermore, the first and second plastic caps in contact with the solid product can allow microwaves to pass through. While fixing the solid product, multiple first and second plastic caps can also uniformly contact and dry it with microwaves. By controlling the motor to operate, the rotating solid product can be dried evenly in all directions, ensuring the drying quality of the equipment.

[0020] This invention, through the arrangement of a pull plate, springs, first metal tubes, and second metal tubes, allows the upward-moving pull plate to drive several second metal tubes to slide upwards within several first metal tubes. Simultaneously, several springs contract, placing the solid product above several second plastic caps. Slowly releasing the pull plate causes the second metal tubes, under the spring force, to bring the first plastic caps into contact with the top of the solid product. This prevents the solid product from moving within the drying chamber during the drying process, ensuring safe drying. Furthermore, the adjustable spacing between the first and second plastic caps allows for the coordinated movement of the moving second and first plastic caps to secure solid products of different sizes, improving the applicability of the device.
