Problems solved by technology

The ambient humidity and temperature in this method are suitable for the production of tobacco worms, and there is a risk of pests
[0004] In addition, although many techniques for drying tobacco products have been disclosed at present, they are all aimed at traditional flue-cured tobacco products, and cigars are tobacco products rolled from dried and fermented tobacco. None of the drying methods of flue-cured tobacco can be directly applied to cigar drying

Embodiment 1

[0026] A cigar vacuum microwave drying process, comprising the following steps:

[0027] (1) Cigars are divided into large cigars with a weight greater than or equal to 6g, medium cigars with a weight of less than 6g and greater than or equal to 3g, small cigars with a weight of less than 3g and greater than or equal to 1.2g, and miniature cigars with a weight of less than 1.2g.

[0028] (2) Place the cigars in different drying devices according to their categories. In each drying device, the cigars are placed in a single row and not stacked in multiple rows.

[0029] (3) Adjust the temperature in all drying devices to -20°C and the vacuum degree to 0.06MPa. After drying cigars of various quality categories for 30 minutes, turn on the microwave source and continue drying at a microwave power of 6KW. When microwave drying, the drying time is 60s for large cigars, 50s for medium cigars, 45s for small cigars and 40s for micro cigars.

[0030] (4) Raise the temperature of all dry...

Embodiment 2

[0035] A cigar vacuum microwave drying process, comprising the following steps:

[0036] (1) Cigars are divided into large cigars with a weight greater than or equal to 6g, medium cigars with a weight of less than 6g and greater than or equal to 3g, small cigars with a weight of less than 3g and greater than or equal to 1.2g, and miniature cigars with a weight of less than 1.2g.

[0037] (2) Place the cigars in different drying devices according to their categories. In each drying device, the cigars are placed in a single row and not stacked in multiple rows.

[0038] (3) Adjust the temperature in all drying devices to -22°C and the vacuum degree to 0.04MPa. After drying cigars of various quality categories for 25 minutes, turn on the microwave source and continue drying at a microwave power of 5KW. Under the microwave, the jumbo cigars dry in 55 seconds, the medium cigars in 45 seconds, the petites in 40 seconds, and the micro cigars in 35 seconds. At the same time, when dry...

Embodiment 3

[0044] A cigar vacuum microwave drying process, comprising the following steps:

[0045] (1) Cigars are divided into large cigars with a weight greater than or equal to 6g, medium cigars with a weight of less than 6g and greater than or equal to 3g, small cigars with a weight of less than 3g and greater than or equal to 1.2g, and miniature cigars with a weight of less than 1.2g.

[0046] (2) Place the cigars in different drying devices according to their categories. In each drying device, the cigars are placed in a single row and not stacked in multiple rows.

Abstract

The invention relates to the technical field of cigar drying, in particular to a cigar vacuum microwave drying process. The method comprises the following steps: placing cigars in a single row in a drying device; adjusting the temperature in the drying device to be -22 to -18 DEG C and the vacuum degree to be 0.04-0.08 MPa, drying for 25-35 minutes, starting a microwave generation source, and continuously drying for 35-65 seconds under the microwave power of 5-8 KW; and heating to 11-12 DEG C, and balancing the moisture of the cigar for 20-28 hours. According to the process, through combination of microwave and vacuum technologies, cigars can be dehydrated at a low temperature and the moisture diffusion rate can be increased at a low pressure, and meanwhile, microwaves provide a heat source for vacuum drying, so that the defect of low heat conduction rate of a conventional convection mode in a vacuum state can be overcome, the drying temperature is reduced, the drying speed is increased. Therefore, the original color, aroma and taste and other effective components of the cigars can be better retained, and better drying quality is obtained.

Description

technical field [0001] The invention relates to the technical field of cigar drying, in particular to a vacuum microwave drying process for cigars. Background technique [0002] Conventional cigars, especially hand-leaf and leaf-bunch cigars, need to be dried twice after processing. Generally, the balance method is used: balance at a temperature of 12-15°C and a humidity of 65±5.0%. In about 7-10 days, the moisture content of the cigars reaches 13.5-15%. During the balance process, the cigarettes need to be sorted out regularly, turned over, changed layers and other related treatments to keep the moisture content of the cigarettes uniform and reduce the deformation of the cigarettes. Broken etc. This kind of cigarette drying process takes a long time to balance, low production efficiency, low degree of automation, uneven moisture in cigarettes, and all cigars are not classified and dried, and the pertinence is not strong. Dry cigars have excessive or excessive moisture cont...
