Flue-cured tobacco upper smoke baking method

Abstract

The invention discloses an upper cured tobacco baking method belonging to the field of cured tobacco baking concocting technology. The feed preparation procedure selects the upper tobacco in delay harvest or half plant harvest mode which harvests leaf and main trunk one time. Rod hanging procedure bakes the half plant of upper cured tobacco stem and leaf together without separating the same. Baking procedure employs three-section baking method, wherein all sections of the baking time are prolonged for more than 3 hours, and the early temperature of bake-yellowing is reduced for 1 to 2 DEG C. After-baking procedure picks the leaf off from the trunk when the leaf becomes a little soft and the main trunk becomes hard and brittle after being taken off from bed. The invention can, in average, enhance orange smoke rate of the upper tobacco for 5.0 % and first-rate tobacco rate for about 4.0 %, price of original tobacco for 1 Yuan per kilogram.

Description

technical field

[0001] The invention belongs to the technical field of flue-cured tobacco curing and modulation. Especially for the roasting and modulation of the upper part of the flue-cured tobacco

[0002] technology field. Background technique

[0003] The availability of the upper tobacco leaves in the prior art is not good, and the industrial demand is relatively small, which causes the contradiction between agricultural production and industrial demand. The existing curing method is to adopt 4-6 pieces of tobacco leaves of the upper part of the tobacco to be harvested in slices at one time, and after harvesting, the slices are tied to the rods, and the roasting is carried out according to the traditional three-stage baking method. When tying the poles, every two leaves are bundled, with the back of the leaves facing outwards, and tied with hemp rope. Three-stage baking is generally divided into three stages: 38-42°C yellowing period, 50-55°C...
