Problems solved by technology

The experimental results showed that the initial moisture content of the tobacco stems was adjusted to 40%-50% for steaming treatment. With the prolongation of steaming time, the moisture content of the tobacco stems increased rapidly from the initial value to 58.14%. The moisture content of the tobacco stems changed after 10 minutes. Therefore, 10 minutes is determined to be the best steaming time for tobacco stems; the initial moisture of tobacco stems is controlled at 40%-50%, and the moisture after steaming treatment reaches 55%-60%. Good; after steaming, the tobacco stems are single-stage rubbed, and the pass rate of the cut stems is 48.63%. fine fraction

Abstract

The invention discloses a method and device for extracting and scattering tobacco stems synchronously. The method comprises the step one of carrying out feeding, wherein the tobacco stems and solvent are fed into a storage tank according to the set proportion; the step two of carrying out stirring, wherein a push type paddle stirrer is started, and the materials in the step one are stirred and mixed uniformly to obtain a tobacco stem mixture; the step three of carrying out scattering while carrying out extracting, wherein a scattering machine is started, the tobacco stem mixture in the storage tank enters the scattering machine under action of stirring and driving force of the push type paddle stirrer, and then flows back to the storage tank through a circulating pulp pipe by utilizing the centrifugal pumping action generated by a rotor and pulp separating blades, so that the materials are extracted and scattered in a circulating mode; the step four of carrying out secondary extracting, wherein the scattering machine is closed for carrying out secondary extraction. While extracting and scattering are completed, the purposes of high extracting efficiency, good scattering quality and low energy consumption are achieved.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves by the papermaking method, and in particular relates to a method and a device for simultaneously extracting and defoliating tobacco stems. Background technique [0002] At present, there are mainly two methods for extraction and deflaking of tobacco stems in the field of papermaking reconstituted tobacco leaves, one is to decompose first and then extract, and the other is to extract and then decompress. [0003] The tobacco stem extraction process currently generally adopts the method of container + hot water + stirring + auxiliary. The mainstream equipment includes leaching tank, multi-functional extraction tank, dynamic extraction tank, heat reflux extraction and concentration unit, ultrasonic enhanced extraction, microwave extraction and other process equipment. Ultrasonic enhanced extraction and microwave extraction are newly developed extraction processes in recent years....
