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 vacuum microwave drying process for cigars, 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 less than 6g and greater than or equal to 3g, small cigars with a weight 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 cigars in different drying devices according to their categories. In each drying device, cigars are placed in a single row, and no multiple rows are stacked.

[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 generating source and continue drying under the 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) The temperature of all d...

Abstract

The invention relates to the technical field of cigar drying, in particular to a vacuum microwave drying process for cigars. It includes the following steps: placing cigars in a single row in a drying device; adjusting the temperature in the drying device to -22--18°C, the vacuum degree to 0.04-0.08MPa, and after drying for 25-35 minutes, turn on the microwave source, Continue to dry for 35~65s at a power of 5~8KW; raise the temperature to 11~12°C, and balance the moisture of the cigars for 20~28h. In this application, through the combination of microwave and vacuum technology, under low pressure, the cigars can be dehydrated at low temperature, so that the water diffusion rate can be accelerated. At the same time, microwaves provide heat sources for vacuum drying, which can overcome the conventional convection method under vacuum. The disadvantage of slow heat conduction rate not only reduces the drying temperature, but also speeds up the drying speed, so it can better retain the original color, fragrance and other active ingredients of cigars, and obtain better drying quality.

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 handmade leaf type and leaf bundle type cigars, need secondary drying after processing. Generally, the balance method is adopted: balance under the conditions of temperature 12-15℃ and humidity 65±5.0% In about 7-10 days, the moisture content of cigars can reach 13.5-15%. During the balancing process, the cigarettes need to be regularly sorted, turned over, and replaced by layers to keep the moisture content of the cigarettes uniform and reduce the deformation of the cigarettes. broken, etc. This cigarette drying process takes a long time to balance, low production efficiency, low degree of automation, uneven moisture content, and all cigars are not classified and dried, and the pertinence is not strong. Dry cigars have excessive or excessive moisture content in the c...
