Energy-saving updraft barn with uniform air supply

Abstract

The invention discloses an energy-saving airflow rising type bulk curing barn capable of achieving uniform air supply. The bulk curing barn comprises a heating chamber and a tobacco charging chamber, wherein the heating chamber and the tobacco charging chamber are separated through a party wall, a hot air channel, a hot air return port and moisture discharge outlets penetrating through the party wall are formed in the party wall, a main air inlet is formed in the bottom of the party wall, two lateral walls of the tobacco charging chamber are each provided with a lateral air inlet, the hot air channel is of a horn mouth structure which becomes wider gradually from the heating chamber to the tobacco charging chamber, and partition boards are arranged on the two sides of the hot air channel respectively to divide the hot air channel into a main hot air channel body and side hot air channel bodies. The main hot air channel body is arranged to be of a trapezoid horn mouth structure, hot air in the heating chamber is sprayed out from the horn mouth so that mixing and disturbance of hot air can be facilitated, the area of the main hot air inlet is increased, the dead corner area between the heating chamber and the tobacco charging chamber is eliminated, and then tobacco leaves in the tobacco charging chamber can be fully cured by the hot air entering the tobacco charging chamber from the heating 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 ascending dense 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 to T...

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
