Abstract

The invention provides a method for preparing products of silk-shaped tobacco stalks. The method is characterized by mainly comprising the following steps: 1) pre-treating the tobacco stalks; 2) the primary defibrination of the pre-treated tobacco stalks to make the water content of the tobacco stalks reach 30 to 60 percent; 3) twisting the tobacco stalks undergoing the primary defibrination into cut stems, of which the width is 1.2 to 2.0mm and the length is 2.0 to 30.0mm; and 4) drying the twisted cut stems until the water content of the cut stems reaches 10 to 13 percent, and perfuming the cut stems by process. In the method, an input-output ratio in actual production is high, and the prepared cut stems do not retain bad aftertaste after being smoked, so that the intrinsic quality is improved; the fill value is high, and the feeding uniformity is good; the colors and shapes of the products of silk-shaped tobacco stalks of the invention are close to the cut tobacco, the distribution of the products of the invention in cigarettes is more uniform than that of the conventional cut stems and tobacco stalk particles, and the rolling performance of the cut stems are improved.

Description

A kind of preparation method of products of silk-shaped tobacco stalks

Technical field

The present invention relates to technical field of tobacco processing, specifically a kind of preparation method of products of silk-shaped tobacco stalks.

Background technology

The offal handling process that the technology for making tobacco threds of cigar mill is commonly used comprises: preliminary treatment (comprising that screening, moisture regain, Terrier Storage, offal heat), press that stalk is cut stalk, stem expands and drying, stem selection by winnowing, operation such as feed in raw material.Have and cut or directly cut stem after earlier swollen, also have and adopt different swelling agents, use microwave or additive method to make expanded cut stem in addition.These technologies are all inevasible to exist following problem: 1. raw material availability is not high, makes input-output ratio low; (2. can not effectively remove the wooden assorted gas in the offal; 3. very difficult mode through flavoring and casing thoroughly improves it and sucks pleasant impression, coordinates the whole fragrance of cigarette product; 4. fundamentally not improving offal stem quality, is sheet on its physical behavior, and color is also big with leaf silk difference, causes post-order process middle period silk and stem to mix and joins inequality.Above deficiency has influenced the stem quality, has restricted the application of offal in medium-to-high grade cigarette.

Chinese patent 200410040042.4 discloses a kind of method of utilizing rubbing offal to be processed into expanded cut stem; Comprise regaining moisture of cabo, beat stalk, wash stalk, Terrier Storage, offal secondary humidification, press stalk, rub operations such as stalk, stem expansion drying with the hands; Though can obtain and the approaching expanded cut stem of pipe tobacco shape, its complex process only replaces cutting stalk with rubbing stalk with the hands than common process; And do not have " the mechanical screws formula is rubbed the stalk machine with the hands " of moulding at present, patent working property is poor.

Summary of the invention

The objective of the invention is the problem to the prior art existence, a kind of preparation method of products of silk-shaped tobacco stalks is provided, this method may further comprise the steps:

1) offal is carried out preliminary treatment;

2) pretreated offal is tentatively separated fibre, make its moisture content reach 30%～60%;

3) will tentatively separating offal behind the fibre, to be twisted into width be 1.2mm～2.0mm, and length is at the stem of 2.0mm～30.0mm;

4) stem after the stranding is dried to moisture content 10%～13%, then by the technology perfuming.

Offal preliminary treatment described in the step 1) comprises the assorting room that metal, impurity in the offal are rejected; Sorting comprises drainage wind branch, dedusting, metal rejecting; Put into the hot water lixiviate to offal 1～2 time then, each 30min, 60 ℃～90 ℃ of water temperatures; The hot water of lixiviate is 1 times～9 times (being preferably 3 times～6 times) of offal weight, and the abundant moisture absorption of offal is run through.

Above-mentioned steps 3) in; The stem length of tentatively separating behind the fibre is preferably 2.0mm～30.0mm; Tentatively separating fine effect is to make offal further loose, soft; And the part Free water in the offal extruded, be convenient to the processing of subsequent handling, this operation can be passed through press master, disc mill, tobacco stem flattener or squeezer and realize; Tentatively separate offal behind the fibre and at moisture content be under the condition of 30%～60% (being preferably moisture content 30%～40%) and rub stalk with the hands, this process can realize through double helix roller type paste mill or high concentration plate mill.

The present invention's input-output ratio in actual production is high, and prepared stem is sucked no bad pleasant impression, and interior quality improves; The filling value is high, and feeding homogeneity is good; Its color, shape and pipe tobacco are approaching, and more traditional stem that in cigarette props up, distributes, cabo particle are even, have improved the cigarette performance of stem.
