Benefits of technology

The patent text describes a method for making cut stems that have more capacity for filling. This means that the stems can hold more liquid or other substances when used in applications such as food or medicine. The goal of the invention is to improve the efficiency and performance of cut stems in these areas.

Problems solved by technology

In the former method, however, there is a limit to reducing the thickness of the rod-like stem material.
In addition, the spreading treatment only crushes the rod-like stem material, and the surface of the rod-like stem material is still covered with a hard epidermis.
As a result, it is difficult to obtain cut stems with high filling capacity even if the rod-like stem material is subjected to shredding and expansion treatments after rolling.
Further, in the latter method, the rod-like stem material includes curved stems or long stems (for example, having a length exceeding 20 cm), and thus it is not practical to successively cut the rod-like stem material in an axial direction.

example 1

[0063]Flue-cured rod-like stems (water content: 26% by weight) made in Brazil were prepared as the rod-like stem material.

[0064]Rollers having the following shapes and peripheral velocities were used as the first and second rollers 31 and 32 in FIG. 3.

[0065]Roller width; 400 mm,

[0066]Roller diameter; 300 mm,

[0067]Cogs on outer peripheral surface of the roller; 8 cogs per inch,

[0068]Height of cogs: 1 mm,

[0069]Interval between the rollers (interval between the tops of the cogs of the first roller and the tops of the cogs of the second roller); 0.7 mm,

[0070]First roller 31: 120 rpm, peripheral velocity of 113 m / minute,

[0071]Second roller 32; 60 rpm, peripheral velocity of 56.5 m / minutes.

[0072]First, the flue cured rod-like stems made in Brazil were supplied from the vibrating feeder 39 to the space between the first and second rollers 31 and 32 rotating under the above conditions at a speed of 300 kg / hr. The flue cured rod-like stems were torn while passing through the first and second...

example 2

[0074]Expanded cut stems were manufactured by a method similar to Example 1, except that the first and second rollers 31′ and 32′ illustrated in FIG. 4 had the following shape and peripheral velocities.

[0075]Roller width; 400 mm,

[0076]Roller diameter; 300 mm,

[0077]Grooves in outer peripheral surface of the roller; 1 groove per inch,

[0078]Depth of groove: 0.5 mm,

[0079]Interval between the rollers (interval between their outer peripheral surfaces); 0.7 mm,

[0080]First roller 31: 120 rpm, peripheral velocity of 113 m / minute,

[0081]Second roller 32: 60 rpm, peripheral velocity of 56.5 m / minute.

Abstract

Method of manufacturing a cut stem with increased filling capacity comprises tearing a rod-like stem material having a water content of 20 to 50% by weight, shredding the torn rod-like stem material, and subjecting the rod-like cut stem material to expansion treatment.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Divisional of U.S. patent application Ser. No. 14 / 038,444, filed on Sep. 26, 2013, which is a Continuation Application of PCT Application No. PCT / JP2011 / 057869, filed Mar. 29, 2011, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method of manufacturing cut stem, a cut stem manufacturing apparatus, and cut stem.[0004]2. Description of the Related Art[0005]Rod-like stems are separated from tobacco leaves, and include internal tissues and an integument existing on a surface of the internal tissues. The rod-like stems occupy 20 to 30% by weight of tobacco leaves. Rod-like cut stems (cut stems) are used for cut tobacco together with cut lamina, from which stems has been removed, for the purpose of effective use of tobacco material. Cut stems are generally obtained by rolling and shredding rod-like stem mat...
