Problems solved by technology

[0003] At present, a variety of tobacco stem pressing technology has been developed in the industry, but the pressed stem slices show thick and stiff stem slices in the subsequent silk-making process, and the prepared cut stems are poor in elasticity and appear needle-shaped, which is greatly broken. , poor blending uniformity with shredded leaves, etc., which limits the proportion and scope of use of microwave-expanded shredded stems in cigarette products, and affects the utilization rate of microwave-expanded cut tobacco stems
[0004] In order to improve the expansion quality and utilization rate of tobacco stems, a variety of tobacco stem pressing technology has been developed in the industry. However, the obtained stem slices are thick and stiff. The silk has poor elasticity and is needle-shaped, with many stalks, and the blending uniformity with leaf silk is poor
None of the current technologies can fully meet the technical needs of the tobacco industry to increase the use value of tobacco stems, which limits the utilization rate of tobacco stems and the proportion and scope of raw materials used in cigarette products

Embodiment 1

[0019] The expanded tobacco stems (expansion degree 380%) after microwave expansion are subjected to first-level stem pressing. After the stalk pressing, three-stage stalk pressing is carried out. After three step-by-step stalk pressing, stalks with a thickness of 0.2mm are produced; the stem foam collection device equipped on the first-level, second- and third-level stalk-pressing devices F, collect the stalk foam produced during the stalk pressing process.

Embodiment 2

[0021] The expanded tobacco stems (expansion degree: 280%) that have been expanded by microwaves are subjected to first-stage compression, the thickness of the stem after compression is 0.9mm, and then the second-level compression is performed, and the thickness of the stem is 0.65mm. After the second-stage stalk pressing, carry out the third-stage stalk-pressing, and after three steps of step-by-step stalk-pressing, the stalks with a thickness of 0.4mm are produced; The collecting device F is used to collect the stem foam generated in the process of pressing the stem.

Embodiment 3

[0023] The expanded tobacco stems (expansion degree: 150%) that have been expanded by microwaves are subjected to first-stage pressing, the thickness of the stem slices is 1 mm, and then the second-stage pressing is performed, and the thickness of the stem slices is 0.7 mm. After the second-stage stalk pressing, carry out the third-stage stalk-pressing, and after three steps of step-by-step stalk-pressing, a stalk with a thickness of 0.4mm is produced; Device F is used to collect the stem foam generated during the stem pressing process.

Abstract

The invention provides a method and apparatus for tobacco stem stagewise sheeting by microwave expansion. The method includes: subjecting microwave-expanded tobacco stems (150%-180% in expansion) to primary stem sheeting, with tobacco sheet thickness being 0.8-1 mm after primary stem sheeting, performing secondary stem sheeting then to obtain thickness of 0.5-0.7 mm, and performing tertiary stem sheeting after secondary stem sheeting to obtain stem sheets having a thickness of 0.2-0.4 mm after triple stagewise stem sheeting. A press roller A and a press roller B form a primary sheeting unit, a press roller C and a press roller D form a secondary sheeting unit, and a tertiary sheeting unit is composed of press rollers D and E. The microwave-expanded tobacco sheets are produced by means of stagewise decrease from great thickness to little thickness, roller sticking rarely occurs during stem pressing by microwave expansion, the obtained stem sheets are uniform in thickness, subsequent shred productivity is significantly improved, few dregs occur, and stem slivers rarely form.

Description

technical field [0001] The invention relates to a method and a device for stepwise pressing stem slices of microwave-expanded tobacco stems, belonging to the technical field of tobacco processing. Background technique [0002] After the tobacco stems undergo the microwave expansion process, the woody gas and miscellaneous gases of the tobacco stems are reduced and the aroma is improved, and the inside of the tobacco stems is porous, which is easy to absorb the feed liquid for quality improvement; It is easier to press into flakes, and it is not easy to break after pressing, and it is easy to further cut into stems for use. [0003] At present, a variety of tobacco stem pressing technology has been developed in the industry, but the pressed stem slices show thick and stiff stem slices in the subsequent silk-making process, and the prepared cut stems are poor in elasticity and appear needle-shaped, which is greatly broken. , Poor uniformity of blending with shredded leaves, e...
