Description

A method for sorting and packing tobacco slices based on their size

technical field

The invention relates to the technical field of tobacco threshing and redrying processing, in particular to a method for classifying and packaging tobacco sheets based on the size of the tobacco sheets after threshing and redrying.

Background technique

At present, the basic process of tobacco sheet packaging is as follows: the loose leaves with a moisture content of 11-13% after rebaking are measured, pre-pressed, re-weighed, packaged and labeled according to certain packaging specifications and quality. The moisture content of the leaf, the packing density and the temperature of the box core will all have an impact on the alcoholization process of the tobacco sheet, thereby affecting the sensory quality of the cigarette product.

With the continuous improvement of quality requirements for Chinese-style cigarettes, the grouping of tobacco leaves in the shredded process has become an industry consensus. At present, group processing is mainly based on the research and analysis of raw material processing characteristics, sensory characteristics and chemical characteristics, to establish the basic principles of raw material grouping, and to determine the appropriate processing routes, processing conditions and flavoring for different modules. However, no attention has been paid to the physical form of the product in the process of silk making. How to realize the differentiated alcoholization rate of tobacco sheets with different physical shapes, and provide conditions for the process of classifying silk with different leaf sizes, there is no relevant solution in the prior art.

Contents of the invention

The purpose of the present invention is to overcome the disadvantages of the prior art, provide a method for classifying and packaging tobacco sheets based on the size, and provide conditions for realizing the classification and shredding of different leaf sizes.

The purpose of the present invention is achieved through the following technical solutions: a method for classifying and packaging tobacco sheets based on the size of the tobacco sheets, during the threshing and re-baking process, the leaves after the threshing and re-baking are classified according to the blade size, Then they are packaged into finished cigarette packs according to the specifications.

The classification is carried out according to principle 1: according to the diameter of the leaves, the leaves are divided into four categories: large, medium, small, and fragments. Among them, the leaves with a diameter range of more than 20mm are large pieces, and the leaves with a diameter range of 10mm to 25mm are Medium slices, leaves with a diameter ranging from 5 mm to 15 mm are small slices, and leaves with a diameter range of less than 5 mm are small slices.

The classification can also be carried out according to the second principle: according to the diameter of the leaves, the leaves are divided into three categories: large and medium pieces, small pieces, and fragments. Among them, leaves with a diameter range of 15 mm or more are large and medium pieces, and the diameter range is 5 mm to 15 mm. The leaves between them are small pieces, and the leaves with a diameter range of less than 5mm are fragments.

The classification preferably adopts an orifice vibrating screen.

The present invention has the following advantages:

1) Realize the classification and packaging according to the size of the leaves, which lays the foundation for the grouping processing of the silk thread, which is conducive to the improvement and promotion of the quality of cigarette products.

2) Through differentiated processing paths and processing intensity, the crushing loss of large, medium and small cigarette chips can be effectively reduced, raw materials can be saved, and costs can be reduced.

3) The difference in the physical shape and packing density of tobacco sheets creates conditions for the selection of alcoholization speed.

4) Minor changes to the existing rebaking production line, easy to implement. The invention is easy to operate and has good application prospects.

FIG. 1 is a schematic process flow diagram of Embodiment 1 of the present invention.

detailed description

Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

Example 1:

As shown in Figure 1, a method of sorting and packing based on the size of the tobacco slices. In the process of threshing and re-baking, the leaves after threshing and re-baking are classified according to the size of the leaves, and then packed according to the specifications. into finished cigarette packs.

The classification preferably adopts an orifice vibrating screen.

The classification principle is as follows: according to the diameter of the leaves, the leaves are divided into three categories: large and medium pieces, small pieces, and fragments. Among them, the leaves with a diameter range of 15 mm or more are large and medium pieces, and the leaves with a diameter range of 5 mm to 15 mm It is a small piece, and the leaves with a diameter range of less than 5mm are fragments.

After different leaves are sorted and packaged, they are sent to the warehouse for targeted alcoholization and use as rebaked finished cigarette packs.

After using this method for classification and packaging, for the subsequent classification and alcoholization, the silk thread is grouped and processed. The subsequent process can adopt targeted processing methods and parameters according to the quality characteristics of different leaves, which provides a basis for effectively comprehensively improving the quality of cigarettes.

Example 2:

A method for classifying and packaging tobacco sheets based on the size of the tobacco sheets. In the process of threshing and re-baking, the leaves after threshing and re-baking are classified according to the size of the leaves, and then packed into finished cigarette packs according to specifications.

The classification is based on the principles: according to the diameter of the leaves, the leaves are divided into four categories: large, medium, small, and fragments. Among them, the leaves with a diameter of more than 20 mm are large, and the leaves with a diameter of 10 mm to 25 mm are medium. The leaves with a diameter ranging from 5mm to 15mm are small pieces, and the leaves with a diameter of less than 5mm are small pieces.

The classification preferably adopts an orifice vibrating screen.

After different leaves are sorted and packaged, they are sent to the warehouse for targeted alcoholization and use as rebaked finished cigarette packs.

After classification and packaging by this method, for the subsequent classification alcoholization and group processing of silk thread, the subsequent process can adopt targeted processing methods and parameters according to the quality characteristics of different leaves, which provides a basis for effectively comprehensively improving the quality of cigarettes.
