A processing technology for improving the utilization rate of expanded cut stem raw materials

Abstract

The invention relates to a processing technology for improving the utilization rates of expanded cut stem raw materials for tobacco. The technology comprises the fifteen steps of tobacco stem screening, tobacco stem microwave expansion, expanded tobacco stem humidification and storage, expanded course tobacco stem slicing, expanded fine tobacco stem sheeting, stem sheet feeding and storage, cut stem sheet shredding, pressed stem sheet shredding, expanded fine tobacco stem shredding, primary cut stem feeding and storage, cut stem shaping and drying, secondary cut stem feeding and storage, press-cut stem flavoring and storage, primary cut stem flavoring and storage and mixed cut stem flavoring and storage. According to the processing technology, different processing processes are adopted according to the cut stem raw materials with different sizes, relatively fine cut stems and fine cut stems which are difficult to process by the conventional technology are fully utilized, the application range of the microwave-expanded cut stems in cigarette making is expanded, the utilization rates are improved, the sensory quality of a microwave-expanded cut stem product is improved, the microwave-expanded cut stem series products with constant physical property and diversified sensory characteristics are obtained, and the purposes for reducing the harmful components in the smoke, reducing the cost and increasing the effect are realized.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a processing technology for improving the utilization rate of raw materials of expanded cut stems. Background technique [0002] With the development of processing technology for expanded cut stems, the existing mainstream expansion technologies mainly include microwave expansion and high temperature and high humidity expansion. Conventional microwave expanded tobacco stem slicing and shredding process is: microwave expansion of tobacco stems, storage of stems, moisture regain, storage of stems, cutting of stems, storage of stems, cutting of stems, feeding, storage of shreds, drying, and flavoring. The process flow is as follows: figure 1 The conventional high-temperature and high-humidity expanded tobacco stem pressing and shredding process is: washing the stem, storing the stem, once pressing the stem, cutting the stem, high temperature and high humidity,...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: (1) If steam explosion is used to expand, the woodiness of the finished stem shreds will be heavy, which will affect the sensory quality

(2) If microwave expansion is used, the moisture content of the microwave-expanded tobacco stems is low, and the texture is relatively brittle. After expansion, the sorting is easy to form fragments, which has a great impact on the subsequent processing technology and has a certain impact on the size uniformity of the finished cut stems.

(3) When the raw materials of tobacco stems of different sizes are subjected to microwave expansion treatment at the same time, the expansion uniformity is poor. When the large-sized tobacco stems reach the appropriate expansion degree, the smaller-sized tobacco stems have already begun to coke, resulting in a scorched smell. affect sensory quality

This method has the following disadvantages: (1) The thin stems are removed as debris, resulting in low comprehensive utilization of raw materials

(2) If the conventional method of pressurization, heating and humidification is used to expand, the finished stem shreds will have a heavy woodiness, which will affect the sensory quality.
