Description

Tobacco curing barn

(1) Technical field:

The utility model relates to a roasting equipment, in particular to a roasting barn for flue-cured tobacco.

(2) Background technology:

Most of the traditional tobacco leaf processing adopts natural drying in the sun. This kind of processing is greatly affected by natural factors, and it will not be able to dry in rainy weather, which affects the quality of tobacco leaves. Later, some barns were also used for drying, but most of the barns were not well sealed, and the temperature and humidity of the barns could not be controlled, resulting in uneven heating. Drying means over-baking, which makes the tobacco leaves black and burnt, and the quality of the tobacco leaves cannot be guaranteed.

(3) Contents of the invention:

The purpose of the utility model is to provide a baking barn for flue-cured tobacco. The device is energy-saving and environment-friendly, has good sealing effect, is evenly heated, and can precisely control the temperature and humidity of the barn in real time, effectively ensuring the quality of tobacco leaves.

In order to achieve the above purpose, the utility model is a baking barn for flue-cured tobacco, which includes a tobacco chamber, a heating room, and a baking oven fixed in the heating room. An automatic temperature and humidity controller that controls the smoke chamber through sensors. There is a heat insulation wall between the left end of the smoke chamber and the right end of the heating chamber. The smoke chamber passes through the vents on the upper and lower parts of the heat insulation wall and the heating chamber. Connected, there is a multi-layer flue-curing rack in the smoking room, a door on the wall at the right end of the smoking room, and a dehumidification window on the upper part of the wall at the right end of the smoking room; a wall at the left end of the heating room A combustion-supporting fan is provided on the left side of the heating chamber. The combustion-supporting fan extends into the lower part of the oven in the heating chamber through a pipe. A circulating fan is installed above the oven in the heating chamber. A cold air inlet is provided on the upper part of the wall at the left end of the heating chamber. A chimney is arranged on the top of the wall above the heating chamber; the walls of the smoke chamber and the heating chamber are all made of thermal insulation materials.

In the above technical solution, since an automatic temperature and humidity controller is fixed on the outer wall of the baking barn to control the smoke chamber through sensors, the temperature and humidity in the smoke chamber can be precisely controlled in real time. A combustion-supporting fan is provided on the left side of the left end wall of the heating chamber and a circulation fan is provided above the baking oven in the heating chamber, which can make the tobacco leaves in the smoking chamber evenly heated and effectively ensure the quality of the tobacco leaves. The walls of the smoke chamber and the heating chamber are made of thermal insulation materials, with good sealing effect, energy saving and environmental protection.

(4) Description of drawings:

Fig. 1 is a structural cross-sectional view of a baking room for flue-cured tobacco of the present invention;

Fig. 2 is a three-dimensional structure schematic diagram of a curing barn for flue-cured tobacco of the present invention.

(5) Specific implementation methods:

Below in conjunction with accompanying drawing, a kind of curing barn for flue-cured tobacco of the present invention will be described in further detail.

It can be seen from Fig. 1 and Fig. 2 that a kind of baking and curing room for flue-curing tobacco in this embodiment includes a tobacco loading room 1, a heating room 2, and a baking furnace 3 fixed in the heating room 2. An automatic temperature and humidity controller 4 that controls the smoke chamber 1 through sensors is fixed on the wall, and an insulating wall 5 is provided between the left end of the smoke chamber 1 and the right end of the heating chamber 2. The ventilation openings 6 on the upper and lower parts of the heating wall 5 communicate with the heating chamber 2. A multi-layer flue-cured tobacco rack 7 is arranged in the tobacco chamber 1, and a tobacco chamber door 8 is provided on the wall at the right end of the tobacco chamber 1. The upper part of the wall at the right end of chamber 1 is provided with a dehumidification window 9. In this embodiment, the dehumidification window 9 adopts an aluminum alloy louver structure, and a dehumidification door is installed at the dehumidification outlet. On the left side of the wall at the left end of the heating chamber 2, a combustion-supporting fan 10 is provided. Circulation blower 11 is provided with cold wind air inlet 12 on the upper part of the wall body of left end of heating chamber 2, and is provided with exhaust chimney 13 on the wall top above heating chamber 2.

In this embodiment, by collecting the values of the dry-bulb and wet-bulb temperature sensors in the smoke chamber in real time, the opening and closing of the combustion-supporting fan 10, the circulation fan 11, the cold air inlet 12, and the humidity exhaust window 9 can be controlled, so as to control the temperature of the smoke chamber. Indoor temperature and humidity are accurately controlled in real time. In this embodiment, the walls of the smoke chamber 1 and the heating chamber 2 are all made of thermal insulation materials, and the door 8 of the smoke chamber adopts two opposite doors to ensure that the smoke chamber is fully open, and is suitable for various smoke loading methods. The thickness of the door is ≥50mm, and the door is made of color steel composite insulation board. The thickness of the color steel plate is ^≥0.375mm . Adopting the technical scheme of this embodiment, it is energy-saving and environment-friendly, has a good sealing effect, is evenly heated, and can precisely control the temperature and humidity of the baking barn in real time, effectively ensuring the quality of the tobacco leaves.

In this embodiment, the barn structure adopts the rising air flow, the circulation fan 11 blows downward, and the hot air enters the smoke chamber 1 from the vent at the lower end of the heat insulating wall 5 . According to the actual needs, the structure of the barn with downward airflow can be adopted. Compared with the structure of the barn with upward airflow, the installation position of the circulating fan is the same, but the installation angle of the fan blades is different, and the direction of rotation of the motor is opposite. the
