Abstract

The invention relates to the tobacco industry and can be used in the development of promising technological schemes for tobacco production, in particular, enterprises for the integrated processing of tobacco raw materials and the production of cut tobacco. The aim of the invention is to reduce losses of tobacco raw materials and energy and labor costs. This is achieved by fermenting the tobacco in a loose mass, then directing it directly to the cutting, followed by drying and cooling. Along with cooling, additional loosening and dusting of tobacco is carried out. Next, shredded tobacco is packaged in plastic bags. When using tobacco of different cultivar types, tobacco bags are compiled before the fermentation process. 1 hp ff.

IND

The invention relates to the tobacco industry and can be used in the development of promising technological schemes for tobacco production, in particular, enterprises for the integrated processing of tobacco raw materials and the production of cut tobacco.

The purpose of the invention is to reduce the loss of raw tobacco and energy and labor costs.

The method is carried out as follows.

Tobacco raw materials are taken from deliverers and stored for some time in warehouses. The form of tobacco packaging intended for processing by the proposed method is not regulated. It can be bales and tobacco bales, i.e. the traditional form of its packaging. However, it is most expedient for processing according to the proposed method to harvest tobacco raw materials in loose weight - in boxes, bags and other containers. Such a simplified packing of tobacco reduces labor costs during the primary processing of raw materials in households, and also simplifies the technology of preparing it for fermentation. At the same time, both during the primary processing of tobacco and in preparing it for fermentation, not only labor costs but also energy consumption and raw material losses in production are reduced. Acceptance and storage of tobacco is carried out by a known technology.

The next group of operations is the preparation of tobacco for fermentation. This includes: selecting batches of tobacco for fermentation, clearing bales and bales, if the tobacco raw material comes in tight packaging, or loading the dispenser when harvesting raw materials in a loose mass, cleaning the tobacco from dust, sand and other impurities. In the production of cut tobacco from tobacco raw materials of several sorts of bag types, the required number of components is compiled when selecting tobacco batches for fermentation.

The tobacco thus prepared with a moisture content of 16-25% is fed for fermentation in a loose mass. In the production of cut tobacco from tobacco raw material of the same type, it is advisable to ferment tobacco leaves with sauces and shock absorbers in the amount of 1.5-2.0% by weight of tobacco using known recipes for this, When using different types and commercial types for producing tobacco raw tobacco The varieties of the components of the bags are fed into the installation one after the other. The mixing of tobacco in this case is carried out in the installation itself, the design of which provides the possibility of carrying out this process.

Hygrothermal treatment of tobacco in the installation is carried out with the following air parameters: in the conditioning zone - a temperature of 60-75 ° C, humidity 30-60%, in the area of fermentation, the temperature is 50-70 ° C,

humidity 75%; in the cooling zone, the temperature is 30-45 ° C, humidity 75-80%. Changing the parameters of air during its hygrothermal treatment (which is usually called fermentation) depending on the type and, mainly, on the moisture content of the tobacco raw material, stabilize the moisture content of the tobacco at unloading from the plant after fermentation. It must be within the optimum range for the process of cutting tobacco, i.e. from 18 to 19%.

After fermentation in loose weight, tobacco is sent directly to the cutting, mine, intermediate operations and processes performed in preparing the tobacco for cutting according to known technology. The cutting of tobacco is carried out on machines of the guillotine or rotary type, mainly according to the existing technology. However, in the production of shredded tobacco according to the proposed method, it is possible to cut tobacco at elevated temperatures without additional energy costs for heating the tobacco, using the heat supplied to the tobacco during fermentation. When cutting warmer tobacco, the amount of waste is reduced, and the quality of the fiber increases, which is a consequence of the increased elasticity of the tobacco leaf tissue with an increase in their temperature. The optimum temperature of the tobacco at which it is cut by the proposed method is 25-40 ° C.

After cutting, the tobacco fiber enters the pneumatic installation, where it is cleaned of impurities and dedusted. Here, too, large glueing of tobacco fibers is broken by the air flow.

The next process is suspending the cut tobacco to a moisture that is optimal for making cigarettes and cigarettes out of it. The drying is carried out mainly in a rotating drum with blades, equipped with a heating and air circulation system of known design. Suspended tobacco is produced within 3-5 minutes. During this time, the humidity of the tobacco decreases to 14.0-15.5%, the temperature rises to 35-45 ° C.

After the undercut, the cut tobacco is fed to the cooling in a pneumatic installation, in which, along with cooling, it is additionally loosened and dedusted. The temperature of the tobacco after cooling is 25-35 ° C, the humidity decreases slightly - by 0.1-0.2%.

Next, the shredded tobacco is packed in polyethylene sheds in a known manner, which are then placed in cardboard boxes. Volumetric, the density of tobacco 150- 300 kg / m, humidity 14-15%. Boxes with shredded tobacco are placed on pallets and stored in the warehouse for at least 2 days, and then transported to tobacco factories.

Example. Raw tobacco - non-fermented, large-leaved, of normal humidity (17-18%), Podolsky 1, 2 and 3 commercial grades were taken to the tobacco-fermentation plant in bales and sent to a warehouse for storage.

To the preparation of tobacco for fermentation, begin with the selection of a batch — the compilation

Chilled shred tobacco with a moisture content of 14.5% is packed in plastic bags with dimensions (55.5x90.0) cm, the weight of tobacco is about 10 kg. Bags of tobacco are sealed and placed in cardboard boxes, and in their absence - on pallets. After a stay for two days, the cut tobacco is sent out. The batch of tobacco in a batch is equal to the daily yield to the tobacco factory for the production capacity of the fourth-class fermentation canning cigarette, installation, in this case 4000 kg. Co-In the production of shredded tobacco, according to the job schedule, for example, shredded tobacco must be released.

The production of fine-cut tobacco for flavored

In this case, the batch includes the following quantities of tobacco served on a pinch, during which or after it, the tobacco leaves are cleaned of impurities. For better mixing, the bales of tobacco of 25 different varieties that are part of the batch are fed alternately to the nipping.

The tobacco prepared in this way is loaded into a loose-weight fermentation plant. Fermented tobacco in ustasigaret and pipe tobacco.
