Energy-saving downdraft barn with uniform air supply

Abstract

The invention discloses an energy-saving type air flow falling type intensive baking room with an air supply function. The energy-saving type air flow falling type intensive baking room comprises a heating chamber and a tobacco containing chamber, wherein the heating chamber and the tobacco containing chamber are partitioned by a public wall; a hot air channel, a hot air return opening and a moisture exhaust opening which penetrate through the public wall are formed in the public wall; a main air inlet is formed in the top of the public wall; a side surface air inlet is formed in the wall surface on each of two sides of the tobacco containing chamber; the hot air channel is of a horn structure of which the width is gradually increased from the heating chamber to the tobacco containing chamber; partition plates are respectively arranged on two sides of the hot air channel and partition the hot air channel into a main hot air channel and side surface hot air channels. According to the energy-saving type air flow falling type intensive baking room, the main hot air channel is of the trapezoid horn structure, so that hot air in the heating chamber is sprayed out from a horn to facilitate hot air mixing disturbance; therefore, the area of a main hot air opening is enlarged, the dead corner region between the heating chamber and the tobacco containing chamber is eliminated, and the hot air entering the tobacco containing chamber from the heating chamber can fully bake tobaccos in the tobacco containing chamber.

Description

technical field [0001] The invention relates to tobacco leaf processing equipment, in particular to a flue-cured barn, in particular to an energy-saving air-flow descending intensive barn with uniform air supply. Background technique [0002] my country is a big tobacco producing country, and there are many tobacco leaf curing houses. The curing quality of tobacco leaves is affected by the temperature and humidity in the smoking room, and the hot air circulation from the heating room to the smoking room determines the temperature and humidity of the smoking room, which directly affects the quality and benefit of tobacco leaves during the tobacco processing process. At present, my country's tobacco leaf curing equipment has begun to build and use dense curing rooms on a large scale. Although it is a forced hot air circulation curing, its overall structure design and construction are random, and there are many defects in the design of the hot air channel structure, which leads...

Problems solved by technology

At present, my country's tobacco leaf curing equipment has begun to build and use intensive curing rooms on a large scale. Although it is a forced hot air circulation curing, its overall structure design and construction are random, and there are many defects in the design of the hot air channel structure, which leads to The indoor temperature and humidity distribution is extremely uneven and difficult to control, there is a dead angle of air flow, the temperature, humidity and wind speed in the horizontal and vertical directions are very different, the changes in the tobacco leaves are very different, and the curing process is inconsistent, which affects the curing quality of the tobacco leaves. Extended baking time, increased energy consumption and baking costs
