Problems solved by technology

In fact, when the steam pressure is greater than 6 bar, the tobacco stems have been completely defibrated. After 1-3 minutes of treating the tobacco stems with 8-10 bar superheated steam, the tobacco stems may be partially decomposed into pulp, which is not conducive to the next step of pressing and cutting.

Embodiment

[0025] Embodiment: the tobacco stem pretreatment process of the present embodiment is carried out as follows:

[0026] A, the tobacco stems are screened to remove impurities, and the impurity removal process includes using screening and impurity removal equipment to screen out broken stems and dust in the tobacco stems and remove impurities such as hemp in the tobacco stems;

[0027] B. Place the tobacco stems after sieving and removing impurities in saturated steam with a pressure of 1.5-4.0 bar and a temperature of 110-143°C for 1-10 minutes;

[0028] C. After the moisture content of the tobacco stems treated with saturated steam reaches 18-30%, the stems are pressed and cut.

[0029] In specific implementation, the pressure of the saturated steam is preferably 2.0-3.0 bar, and the processing time of the tobacco stems in the saturated steam is preferably 3-5 minutes; after the moisture content of the tobacco stems is preferably 20-25%, it is Squeeze and cut stems.

Abstract

The invention discloses a tobacco stalk pretreatment process. The process comprises the following steps of: A, removing impurities from tobacco stalks by screening, namely, screening broken stalks and dust in the tobacco stalks and removing impurities such as untarred jute spun yarn and the like in the tobacco stalks by using screening and impurity-removing equipment; B, putting the screened tobacco stalks from which the impurities are removed into saturated steam at the temperature of between 110 and 143 DEG C and under the pressure of between 1.5 and 4.0 bar to process for 1 to 10 minutes; and C, pressing and cutting the tobacco stalks after the water content of the tobacco stalks treated with the saturated steam is up to 18 to 30 percent. The tobacco stalks pretreated by the process have no water stain on surfaces, uniform internal and external water content and high flexibility, and subsequent stalk pressing and cutting qualities are improved effectively.

Description

Technical field: [0001] The invention relates to a pretreatment process for tobacco stems, in particular to a technique for moistening tobacco stems with saturated steam. Background technique: [0002] Tobacco stem pretreatment mainly refers to the warming and humidification of tobacco stems. The purpose is to make the fibrous tissue and cells of tobacco stems fully and evenly absorb water, so as to improve the softness, plasticity and processing resistance of tobacco stems, so as to meet the requirements of pressing stems. And the process requirements of cutting stems, reduce the breakage and ash loss of tobacco stems in the process of pressing and cutting. [0003] At present, the tobacco stem pretreatment process commonly used in the tobacco industry is: the original stem is gradually rehydrated to the required moisture content through several stages of processing. Fully hygroscopic, storage time may be as long as 24 hours. After storing the stems, it is generally neces...
