Abstract

The invention discloses a method for improving the size uniformity of leaves after threshing. By combining suspension winnowing and air-suction pneumatic sorting, the winnowing frequency of the winnowing device is increased, and the amount of winnowing leaves is improved, and the tobacco stems The super large ones are separated separately for the separation of the tobacco stems. After the separation, the leaves are subjected to secondary winnowing and threshing. The leaf stems are moistened and cut into shreds separately, which controls the production of non-smoking substances in the process of tobacco leaf processing, and satisfies the refinement of cigarette manufacturers on the purity of tobacco sheets. and increase the processing flow rate, reduce production costs, and classify and beat the leaves, reduce the rate of broken tobacco, increase the rate of medium slices, and control the uniformity of tobacco leaves, which is beneficial to subsequent processing. The improvement provided by the present invention The method of blade uniformity has a remarkable effect, effectively improves the efficiency of threshing leaves, and improves the quality of finished tobacco tobacco, which is worth popularizing.

Description

A Method for Improving the Uniformity of Leaf Size after Threshing

technical field

The invention relates to the technical field of tobacco processing, in particular to a method for improving the size uniformity of leaves after threshing.

Background technique

In the production of threshing and redrying, the sheet shape of threshed tobacco directly affects the quality of tobacco, and is also one of the main factors affecting the filling capacity of rolled tobacco. In recent years, domestic and foreign studies on the relationship between the structure of shredded tobacco and the shape of tobacco sheets that meet the needs of high-speed cigarette rolling machines have shown that when the size of tobacco sheets is larger than 35 mm, the increase in filling capacity is not obvious, and it will affect the working efficiency of cigarette machines; When the size is less than 10 mm, the filling capacity of shredded tobacco drops sharply. Therefore, the optimum range of the size of the tobacco is 10-35mm, and the proportion of the cigarette between the large and medium slices after beating should be increased accordingly. In addition, in the subsequent processing of the leaf threshing section, the balanced ratio of length and width of threshing lamina can reduce the shrinkage rate of cured lamina, improve the pass rate and output rate of large and medium-sized lamina of finished tobacco, and increase the quality of cigarettes and duplication. Toast the economics of the business. However, at present, the post-threshing lamina produced by the threshing and re-baking line generally has problems such as a high rate of large sheets and unreasonable sheet shape structure, which leads to a high shrinkage rate of the post-cured lamina and affects the pass rate of large and medium-sized sheets of finished tobacco. , so need a kind of threshing method that improves the passing rate of the middle slice after threshing, reduce the amount of small leaves, reduce the amount of large leaves, in order to improve the quality of the sheet tobacco.

Contents of the invention

The purpose of the present invention is to remedy the defects of the prior art and provide a method for improving the uniformity of blade size after threshing.

The present invention is achieved through the following technical solutions:

A method for improving the size uniformity of leaves after threshing, comprising a base, air separation equipment, temperature increasing and humidifying equipment, leaf toppers and shredding equipment, the base is provided with a fixing groove, and the inner bottom wall of the fixing groove is provided with Through the leaf outlet on the bottom surface of the base, the air separation equipment is set in the fixed groove, the bottom of which communicates with the leaf outlet and is provided with a feeding port. There is a graded leaf building box inside the air separation equipment, which is divided into large, medium and small pieces. and petiole leaves, there is a conveyor belt at the bottom of the leaf building box, and the large and medium pieces are sent to the heating and humidifying equipment through the conveyor belt. After the tobacco leaves are loose and moist, they are sent to the leaf threshing equipment by the feeder for leaf threshing and screening, and the small pieces are bypassed. In the leaf beating process, after increasing the temperature and humidity, it is transported to the shredding process. The petiole leaves are sent to the petiole separation processor through another conveyor belt. After being cut, they are divided into two paths. In the shredded process, the leaf base part of the road is moistened and then separated from the stems. After separation, the leaves return to the air separation equipment for classification and immersion into the next process.

A method for improving the uniformity of blade size after threshing. The air separation equipment is a compound air separation machine, which is composed of a combination of suspension air separation and suction pneumatic conveying up and down. Tobacco leaves of different sizes are selected, and classified and stored according to the leaves with large leaves greater than 35mm, medium leaves with 10-35mm, and small leaves less than 10mm.

A method for improving the size uniformity of leaves after beating. The topper is a hybrid topper with a structure of a mixed rhombus frame, rectangular beating knives and trapezoidal beating knives. The beating roller is in the form of a disc Type structure, the knives are arranged in a straight line, and the shape of the knife is rectangular.

A method for improving the size uniformity of leaves after threshing, wherein the leaf stem separation device is also provided with a vibrating screen structure to screen the obtained leaf stems, and one path is tobacco stems with a diameter of 3-5mm and a length of 20-50mm , all the way to classify and collect tobacco stems with a diameter of 5-7mm and a length of 20-50mm.

The advantages of the present invention are: the method for threshing leaves provided by the present invention improves the air separation frequency of the air separator through the combination of suspension winnowing and suction pneumatic sorting, increases the amount of winnowing blades, and separates super large tobacco stems. Separation is carried out for the separation of tobacco stems. After the separation, the leaves are subjected to secondary winnowing and threshing, and the leaf stems are moistened and cut into shreds separately to control the production of non-smoking substances in the process of tobacco leaf processing, which meets the refined needs of cigarette companies for the purity of tobacco sheets. Moreover, the processing flow rate is improved, and the production cost is reduced. Classifying and beating the leaves reduces the rate of broken tobacco and increases the rate of middle slices, so that the uniformity of the tobacco leaves is controlled, which is beneficial to subsequent processing. The improved uniformity of the leaves provided by the present invention The method has remarkable effect, effectively improves the efficiency of leaf threshing, and improves the quality of finished cigarette, which is worth popularizing.
