Abstract

The utility model relates to baking and modulating equipment for fresh tobacco used for the producing and planting of baking tobacco. The tobacco baking machine is a rectangle box body which is composed of a metal frame and a metal composite plate. The box body is divided into three sections, namely, a tobacco loading chamber, an air channel equipment room and an instrument operational room. The bottom of the tobacco loading chamber is provided with a full hole plate jet flow blowing structure, the lower side of a bottom plate is a delivery conduit of a slope-shaped changeable sectional plane, the top of the bottom plate is provided with air return of small holes and a composite air channel of an air discharge changeable sectional plane, and the air return is composed of crosswise laying plates. Because of the structure, the temperature, humidity and velocity field in the tobacco loading chamber are uniform, the quality of baking tobacco leaves can be improved, and the baking quality can reach more than 95 percent. Because the structure of the metal composite plate is adopted, the energy loss is minimum, and energy consumption is reduced.

Description

The energy-saving baking cigarette of high efficiency machine

The utility model is in a kind of cured tobacco production plantation, the baking modulating equipment of bright cigarette.

At present, the equipment of domestic and international bright cigarette baking mainly is two kinds, the first " baking cigarette room ", it is by a houselet, establishes melt pit in the room, and dependence ground a heatable brick bed heated baking is hung the bright cigarette in the room, the baking cigarette puts in a skylight on the room, and the hole of blowing in down relies on free convection or installs electric fan additional and gets rid of moisture.Because temperature, humidity and velocity field are extremely inhomogeneous in its room, and the constant temperature instability, the fluctuation that heats up is big, so baking quality is very poor, and is general only 13～16%, and energy consumption is big.Another kind of baking cigarette equipment is baking cigarette machine, is assembled by metallic plate, generally adopts and establishes bar seam or mesh floor blowing in fuel oil, combustion gas or electricity consumption heated baking, the case, and the floor divides into the uiform section plenum chamber, and the case top is the uiform section air-return duct.Bright cigarette is hung and is adopted baroque compound cigarette folder, and tobacco leaf density is big.Wait reason to cause the temperature inside the box, humidity, velocity field inhomogeneous in sum, and gas-flow resistance is excessive, it is not smooth to ventilate, and energy consumption is big, and baking quality only reaches 70～80%.

The purpose of this utility model provides the energy-saving baking cigarette of a kind of high efficiency machine makes its inside have even temperature, humidity and velocity field, dries by the fire the cigarette quality to improve, and cuts down the consumption of energy.

The utility model is realized as follows, accompanying drawing is the structural representation of baking cigarette machine, as shown in the figure, the rectangular box that this baking cigarette machine is made up of metal framework and composite metal plate, this casing is divided into three sections, be cigarette-filling house [1], air channel equipment room [2] and instrument operation room [3] are by being covered with the full orifice plate jet distribution structure that the plate of flanging constitutes around ribbing under 5～10 millimeters the rectangle in aperture or the rectangle on it at cigarette-filling house's base plate [4].Being domatic variable cross-section air delivery duct [5] below base plate, is return air [6] and air draft [7] the variable cross-section compound air duct that has the canted-plate formation of aperture at its top.One end of exhausting duct is provided with the automatic exhaust valve of adjustable balanced type [8].Hang tobacco rod or the cigarette folder [13] that tobacco leaf uses and be placed on the longeron [12] that is contained on the metal framework, cigarette-filling house's one end is provided with the external door [14] for the loading and unloading tobacco leaf, and door is provided with the double-layer heat insulation observation window, and the other end is connected with air channel equipment room [2].Blower fan [10] in the equipment room of air channel is connected by up-small and down-big guiding airduct with heater [11], and to the full section air-supply in air delivery duct.The other end of air channel equipment room is connected with instrument operation room [3], is provided with equipment such as automaton and self-regulating air-valve [9] and water (vapour) valve in the instrument operation room.The other end of instrument operation room is provided with the external door [15] of coming in and going out for operating personnel, and equipment such as boiler and water pump connect the formation heating system with pipeline with heater outside baking cigarette box body.

The energy-saving baking cigarette of high efficiency described in the utility model machine can be made different capacity according to actual needs, and based on fire coal, also can change to fuel oil, combustion gas or electricity consumption.Because it has adopted variable cross-section, balanced ventilation road, inclined plane, has guaranteed that full orifice feeding is even.Owing to adopted the metal composite plate structure,, cut down the consumption of energy to reach the energy loss minimum.Because in cigarette-filling house and have than uniform temperature, humidity and velocity field, improved baking quality, baking quality can reach more than 95%.This baking cigarette machine be except that can carrying out the baking of tobacco leaf, can also be applied in agricultural part product as, seed, medicinal material, dried mountain products or the oven dry of raw material of industry product are used.
