Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a principle of heating and dehydrating using microwave technology, which effectively solves the situation that the moisture content of the tobacco leaves after drying is not uniform due to the different moisture content of the tobacco leaves before drying and the different positions of the tobacco leaves; At the same time, because the microwave heating and dehydration process is a uniform process, the tobacco leaves will not be curled, and the adults, larvae and eggs of harmful tobacco insects can be effectively killed. The method of using microwave technology for tobacco leaf threshing and redrying

Embodiment 1

[0013] Embodiment 1: The method steps are as follows 1. Leaf distribution: the tobacco leaves are evenly and neatly placed on the conveyor belt, and the heads are in the same direction;

[0014] 2. Untie the handle: Untie the cigarette handle with a mechanical rotary knife, and the untie rate is 80%;

[0015] 3. Moisturizing: heat and humidify the tobacco leaves to make the tobacco leaves soft and loose, and improve the processing resistance of the tobacco leaves. After moistening the leaves, the moisture content of the tobacco leaves reaches 17%, and the temperature reaches 50°C;

[0016] 4. Threshing and destemming: use a leaf thresher and an air separator to separate the tobacco stems and leaves of the tobacco leaves; the moisture content of the separated leaves is 15%;

[0017] 5. Microwave drying: spread the leaves evenly on the mesh belt, the thickness of the leaves is uniform, and then use microwaves to dry the leaves, so that the water content of the leaves is dried fr...

Embodiment 2

[0019] Embodiment 2: the method steps are as follows: 1, leaf distribution: the tobacco leaves are evenly and neatly placed on the conveyor belt, and the direction of the head is consistent;

[0020] 2. Untie the handle: Untie the cigarette handle with a mechanical rotary knife, and the untie rate is 90%;

[0021] 3. Moisturizing: heat and humidify the tobacco leaves to make the tobacco leaves soft and loose, and improve the processing resistance of the tobacco leaves. After moistening the leaves, the moisture of the tobacco leaves reaches 20%, and the temperature reaches 70°C;

[0022] 4. Threshing and destemming: use a leaf thresher and an air separator to separate the tobacco stems and leaves of the tobacco leaves; the moisture content of the separated leaves is 18%;

[0023] 5. Microwave drying: spread the leaves evenly on the mesh belt, the thickness of the leaves is uniform, and then use microwaves to dry the leaves, so that the water content of the leaves is dried from ...

Abstract

A microwave technology for treating tobacco leaves includes uniformly and orderly spreading tobacco leaves on conveying belt, heating to 50-70 deg.C while moistening it, separating out stems, microwave drying, and packing.

Description

(1) Technical field [0001] The invention relates to a tobacco leaf redrying process, which belongs to the technical field of tobacco leaf treatment. (2) Background technology [0002] At present, in the process of tobacco leaf threshing and redrying, the tobacco leaf drying process uses steam for heat exchange, and then circulates hot air to dry the tobacco leaves. Due to the different moisture content of the tobacco leaves before drying, the thickness of the tobacco leaves during drying due to the thickness of the tobacco leaves. The positions are also different, which means that the dehydration of the tobacco leaves is also different during the drying process, resulting in poor moisture content uniformity after the tobacco leaves are dried. At the same time, due to the different moisture content of the tobacco leaves before drying, the tobacco leaves are prone to curling during the drying process, and the tobacco leaves are folded in the final packing process, which affect...
