Abstract
The invention discloses a cut tobacco drying process, which comprises the following steps: adding 300-320KG/H steam into the hot air duct 15 seconds after the tobacco shreds enter the belt weigher before the tobacco shred baking tube, reducing the steam to about 150-200KG/H after 180 seconds, and closing the steam after 240 seconds; and after the current is cut off for 240 seconds by the belt weigher in front of the cut tobacco drying pipe, 300KG/H steam is sprayed into the hot air pipe, and after the steam is sprayed for 230 seconds and 260 seconds, the exhaust air door is closed. The device comprises a silk drying pipe, a hot air pipe, a heating circulating pump and a hot air circulating pipe, wherein the silk drying pipe, the hot air pipe, the heating circulating pump, the hot air circulating pipe and the silk drying pipe are sequentially connected to form hot air circulation of the silk drying pipe, a steam injection pipe is arranged on the hot air pipe, and the other end of the steam injection pipe is connected with a steam generator. The invention sprays steam to the hot air pipe at the beginning and the end of the cut tobacco drying, can improve the moisture of the cut tobacco and greatly reduce the scrap quantity of the cut tobacco during the cut tobacco drying.
Description
Technical field
The present invention relates to a kind of baking tabacco scrap technology.
Background technology
Existing baking tabacco scrap is that pipe tobacco is removed most moisture by the baking fiber tube, reach the purpose of oven dry pipe tobacco, but in existing baking tabacco scrap process, because the temperature of baking fiber tube is higher, the captacula of pipe tobacco and tailfiber dehydration too much become fragile, cause pipe tobacco to scrap, about about 26 kilograms of the captacula that the production of each baking silk is scrapped, about 35 kilograms of tailfibers.
Summary of the invention
The purpose of this invention is to provide a kind of baking tabacco scrap technology, to overcome the shortcoming that captacula and tailfiber descend and become fragile too much and cause pipe tobacco to scrap because of moisture in the existing baking tabacco scrap process.
Another object of the present invention provides a kind of baking tabacco scrap device.
For realizing above-mentioned purpose, baking tabacco scrap technology of the present invention may further comprise the steps:
1) belt conveyer scale adds 300-320KG/H steam in hot-blast main after 15 seconds before pipe tobacco enters the baking fiber tube, is reduced to about 150-200KG/H 220-260 steam off after second after 180 seconds;
2) 300KG/H steam is sprayed in the belt conveyer scale cutout in warm-air pipe after 240 seconds before the baking fiber tube, sprays 230-270 and closes the waste gas air door after second.
In the step 1) of above-mentioned baking tabacco scrap technology, at first preheating baking fiber tube is 3-5 minute, stop to heat 5-8 minute after, feed intake again.
Above-mentioned steps 1) in, pipe tobacco enters belt conveyer scale steam off after 240 seconds before the baking fiber tube.
Above-mentioned steps 1) in, pipe tobacco enters belt conveyer scale steam off after 260 seconds before the baking fiber tube.
Described step 2) in, uperize is closed the waste gas air door after 260 seconds.
A kind of baking tabacco scrap device, comprise baking fiber tube, warm-air pipe, heat cycles pump, hot air circulation pipe, baking fiber tube, warm-air pipe, heat cycles pump, hot air circulation pipe, baking fiber tube connect to form the hot air circulation of baking fiber tube successively, warm-air pipe is provided with steam-jet siphon, and the other end of steam-jet siphon is connected with steam generator.
Advantage of the present invention:
1) belt conveyer scale added steam before pipe tobacco entered the baking fiber tube in hot-blast main after 15 seconds, and pipe tobacco captacula moisture can reach 8%-10%, and the pipe tobacco feel is more soft and moist, and pipe tobacco captacula learies about 26 kilograms during by uperize not drop to the 0-5 kilogram.
2) before the baking fiber tube belt conveyer scale cutout after 240 seconds in warm-air pipe uperize, make pipe tobacco tailfiber moisture rise to 12%-13.5% and continue about two minutes by about 10%, significantly improved the moisture of pipe tobacco in these two minutes, the learies of tailfiber never about 35 kilograms during uperize drops to about 25 kilograms.
Description of drawings
Fig. 1 is the structure chart of baking tabacco scrap device.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
The specific embodiment
Referring to Fig. 1, Fig. 1 is the structure chart of baking tabacco scrap device, and 1 is the baking fiber tube, 2 is warm-air pipe, and 3 for advancing the silk mouth, and 4 is filament mouth, 5 is the waste gas air door, 6 is the heat cycles pump, and 7 is steam-jet siphon, and 8 is steam generator, 9 is the hot air circulation pipe, baking fiber tube 1, warm-air pipe 2, heat cycles pump 6, hot air circulation pipe 9, baking fiber tube 1 connect to form the hot air circulation path of baking fiber tube 1 successively, and warm-air pipe 2 is provided with steam-jet siphon 7, and the other end of steam-jet siphon 7 is connected with steam generator 8.
Embodiment 3, and preheating baking fiber tube 5 minutes stopped to heat 8 minutes, and preceding belt conveyer scale charging added 320KG/H steam after 15 seconds in hot-blast main, be reduced to 200KG/H after 180 seconds, and steam off after 220 seconds produces 6 kilograms of captaculas; 300KG/H steam is sprayed in the belt conveyer scale cutout in warm-air pipe after 240 seconds before the baking fiber tube, sprays and closes the waste gas air door after 270 seconds, produces 23 kilograms of tailfibers.
