Description

Technical Field

[0001] This utility model relates to the field of tobacco technology, and in particular to a rotary tobacco roasting machine. Background Technology

[0002] Tobacco is an annual herbaceous plant belonging to the genus Nicotiana in the family Solanaceae. Tobacco curing is a core step in the tobacco production process and plays a decisive role in the final quality of tobacco.

[0003] Currently, existing curing machines use a static curing method, where the tobacco leaves remain stationary in the curing chamber. This results in uneven heating of the tobacco leaves in different locations within the chamber. Tobacco leaves closer to the heat source may become scorched due to overheating, affecting the taste and aroma of the tobacco. Tobacco leaves farther from the heat source may be under-cured, leading to the tobacco leaves failing to meet quality standards in terms of color and texture. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven heating of tobacco leaves caused by existing static curing methods, and to propose a rotary tobacco curing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary tobacco curing machine includes a drying chamber. Rotary discs are rotatably engaged on both inner walls of the drying chamber. Two second clamping plates are fixedly connected between the two rotating discs. A first clamping plate is connected to the top of the second clamping plates via a hinge. A latch is fixedly connected to one side of the first and second clamping plates. A connecting plate is fixedly connected to one side of one of the rotating discs. The circumference of the connecting plate is provided with multiple sliding grooves. A mounting frame is fixedly connected to one outer wall of the drying chamber. A motor is fixedly connected to the top of the mounting frame. A connecting rod is fixedly connected to the output end of the motor. A lever is fixedly connected to the other end of the connecting rod. The lever can be engaged in the sliding groove.

[0007] Furthermore, a sealing door is rotatably connected to one side of the drying oven, and a handle is fixedly connected to the outer wall of one side of the sealing door.

[0008] Furthermore, a dustproof net is snapped onto the bottom of the drying oven, and two fans are fixedly connected between the inner walls on both sides of the drying oven, located above the dustproof net.

[0009] Furthermore, heating tubes are fixedly connected between the inner walls of both sides of the drying oven, and the heating tubes are located at the bottom of the first clamping plate and the second clamping plate.

[0010] Furthermore, the top of the drying oven is fitted with an observation window, and the top of the drying oven is provided with an air vent.

[0012] Furthermore, a handle is fixedly connected to one side of the outer wall of the first clamping plate, and the outer wall of the handle is provided with an anti-slip pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor, the connecting rod rotates, causing the lever to engage in the groove. The lever then rotates the connecting disc, which in turn rotates the rotating disc, causing the first and second clamping plates to rotate. This process rotates and dries the tobacco leaves, resulting in uniform drying of the tobacco leaves.

[0015] 2.
