Description

Device for improving alcoholization quality of tobacco

Technical Field

The application relates to the technical field of tobacco processing, in particular to a device for improving alcoholization quality of tobacco.

Background

The alcoholization of tobacco is an important link for improving the quality of tobacco. The tobacco is naturally alcoholized without special process equipment for 1-3 years. In order to shorten the tobacco alcoholization time and improve the tobacco alcoholization quality, the artificial alcoholization of tobacco becomes an important topic for the research of tobacco processing enterprises. After biochemical agents are added into the tobacco through artificial alcoholization, the tobacco is stored in alcoholization room under certain process conditions to accelerate the alcoholization speed of the tobacco and improve the alcoholization quality of the tobacco.

Currently, the alcoholization of tobacco is mainly to put tobacco materials into an alcoholization warehouse or a closed storage cabinet with constant temperature and humidity, almost all alcoholization is in a standing storage mode, and the temperature and oxygen required by alcoholization are supplemented into the alcoholization warehouse or the alcoholization storage cabinet through hot air introduced circularly.

However, in the alcoholization apparatus provided in the prior art, hot air for supplementing temperature and oxygen is often introduced from the top, bottom or even corners of the alcoholization cabinet, the heating of each layer of the tobacco material still in the alcoholization cabinet is not uniform, and the heating of the wind-exposed side and the wind-unexposed side of each layer of tobacco material is also not uniform. For example, CN201142926Y provides a multifunctional tobacco moisture balancing cabinet, in which a hot air inlet is provided at the bottom of the cabinet body, when the cabinet is used for storage, the tobacco leaves at the bottom and top layers are not uniformly heated and contacted with air, and because the time for the tobacco leaves to flow to a discharge port is 45min when the cabinet is used, the cabinet is more suitable for warming and humidifying before alcoholization. CN108713791A discloses a tobacco alcoholization apparatus and method, wherein hot air is introduced and steam is sprayed by a steam nozzle for humidification when a turnover cylinder is used for turning over materials, however, continuous multiple turning over can cause breakage, and further the integrity of tobacco materials is damaged.

Therefore, the temperature, humidity and oxygen content uniformity of the alcoholization environment are all the keys for improving the artificial alcoholization quality of the tobacco, and because the tobacco materials are tiled and have certain density during alcoholization, the above heating and humidifying modes are difficult to ensure that all the tobacco materials can be in full contact with air, so that the oxidation degree is not high, and the alcoholization quality is not favorably improved.

The first conveyor is provided with a material receiving end and a material dropping end, wherein the material receiving end is used for receiving materials, the material dropping end is used for dropping materials, obviously, at least two first conveyors which are arranged from top to bottom in a layered mode and are opposite to each other in conveying direction are arranged inside the alcoholization chamber 1, the material receiving end of the first conveyor at the uppermost layer corresponds to the material inlet 101 of the alcoholization chamber 1, and the material dropping end of the first conveyor at the lowermost layer corresponds to the material outlet 105 of the alcoholization chamber 1, so that the tobacco materials drop to the first conveyor at the next layer in sequence after falling from the material inlet 101 to the first conveyor at the upper layer, are in a state of freely falling and being capable of being turned over in the process of dropping to the first conveyor at the next layer, are finally conveyed to the material outlet 105 and can directly flow out of the alcoholization chamber 1 from the material outlet 105, or enter the material lifter 2 and are lifted to the first conveyor at the upper layer.

Wherein the first conveyor comprises at least a top conveyor 103 near the top of the alcoholization chamber 1, and a bottom conveyor 104 near the bottom of the alcoholization chamber 1. In the embodiment shown in fig. 1, the first conveyor is only provided with two conveyors, namely, the top conveyor 103 and the bottom conveyor 104, so as to fully balance the turnover effect and the breakage problem caused by blanking. Moreover, the material receiving end of the top conveyor 103 is arranged corresponding to the material inlet 101, and the material discharging end of the bottom conveyor 104 is arranged corresponding to the material outlet 105, so that tobacco materials entering the interior of the alcoholization chamber 1 from the material inlet 101 can fall to the material receiving end of the top conveyor 103, and fall to the material receiving end of the bottom conveyor 104 after being conveyed to the material discharging end of the top conveyor 103, and finally fall out of the alcoholization chamber 1 through the material outlet 105 at the material discharging end of the bottom conveyor 104.

With continued reference to fig. 1, a guide rake plate 109 is disposed above the blanking end of the first conveyor, wherein an included angle is formed between the axis of the guide rake plate 109 and the conveying direction of the tobacco material on the first conveyor, as shown by an included angle α in fig. 1, and the included angle α is 30 ° to 75 °, preferably 30 °, 45 °, 60 °, 70 °, or 75 °.

Wherein, the setting of direction harrow flitch 109 can play the effect to material direction and restriction throughput simultaneously to, owing to restricted the direction of dropping of tobacco material and the space that will pass through when dropping, consequently can make the tobacco material that is located the blanking end reach loose, ration and effect that drops in order, further promoted dropping of tobacco material dispersion, in order to guarantee that all tobacco materials and moist hot air contact more fully, promote the homogeneity of material and moist hot air contact. In one embodiment, the guide rake plate 109 may be a flat plate, and in another embodiment, the guide rake plate 109 may be provided with rake nails or the like near the blanking end. Preferably, the ends of the guide rake plate 109 extend at least to the central axis of the first conveyor to more effectively guide the tobacco material. More preferably, the axis of the guide rake plate 109 is a predetermined distance from a tangent to the first conveyor's axis parallel to the axis, for example, the oblique side of the angle α in fig. 1 can be regarded as a tangent to the first conveyor's axis parallel to the axis, and preferably, the predetermined distance is 2-15cm, more preferably 5cm or 10 cm.

The guide rake plate 109 with the above arrangement can also improve the accuracy of dropping the material to the receiving end of the lower first conveyor on the basis of guiding and limiting the throughput. Optionally, the first conveyors of the plurality of layers may be arranged in a layered and staggered manner, but the guide rake plates with the arrangement can also assist in shortening the length of the non-overlapping part of two adjacent first conveyors, so that the overall size of the alcoholization chamber is reduced, the structure in the alcoholization chamber is more compact, and the heat loss of wet hot air can be reduced.

Continuing to refer to fig. 1, the receiving end of the first conveyor is provided with a striker plate 110, preferably, an included angle is formed between the axis of the striker plate 110 and the central axis of the first conveyor, and the included angle is set so as to ensure that the dropped material can accurately fall to the receiving end of the first conveyor on the next layer, thereby avoiding loss caused by the falling material.

Wherein, the interior of the alcoholization chamber 1 is further provided with a grating sensor 107 for controlling the operation of the first conveyor, as shown in fig. 1, the grating sensor 107 is preferably arranged near the first conveyor, and can be used for controlling the start or stop of the first conveyor, for example, arranged at the receiving end of the top conveyor 103 for starting the first conveyor after sensing the material entering, and/or arranged at the blanking end of the bottom conveyor 104 for stopping the first conveyor after sensing the material being full, and also can be used for controlling the conveying speed of the first conveyor; it may also be used to control the level at which the material is laid on the first conveyor, for example being located at a specific height above the first conveyor, the first conveyor being activated when the tobacco material reaches the specific height.

As shown in fig. 1, a material lifter 2 is further disposed inside the chamber of the alcoholization chamber 1, wherein the material lifter 2 has a lifting inlet 201 adjacent to the outlet 105, and a lifting outlet 202 adjacent to the inlet 101, i.e. the lifting inlet 201 corresponds to the blanking end of the bottom conveyor 104, and the lifting outlet 202 corresponds to the receiving end of the top conveyor 103. Moreover, a flap door 203 for closing the discharge port 105 or lifting the inlet 201 is arranged at the discharge port 105, the flap door 203 is hinged with the alcoholization chamber 1 at the discharge port 105, when the flap door 203 is in a state of closing the discharge port 105 (i.e. the flap door 203 is in a state of blocking the discharge port 105 at the right side in fig. 1), the tobacco material conveyed to the blanking end of the bottom layer conveyor 104 is fed into the lifting inlet 201 of the material lifter 2 and lifted to the lifting outlet 202 by the material lifter 2, and then falls to the receiving end of the top layer conveyor 103 from the lifting outlet 202 through the material internal circulation feed port 102; when the flap door 203 is in a state of closing the lift inlet 201 (i.e., the flap door 203 is in a state of blocking the lift inlet 201 at the left side in fig. 1), the tobacco material conveyed to the blanking end of the bottom conveyor 104 can directly fall out of the alcoholization chamber 1 through the discharge port 105. So configured, when tobacco material enters the lifting inlet 201 from the material dropping end of the bottom conveyor 104 and falls out from the lifting outlet 202 to the material receiving end of the top conveyor 103, one material turning can be performed respectively.

In the embodiment shown in fig. 1, the opening direction of the lift inlet 201 is substantially perpendicular to the opening direction of the discharge port 105, and similarly, the opening direction of the lift outlet 202 is substantially perpendicular to the opening direction of the feed port 101. And the lifting outlet 202 is higher than the feeding inlet 101, because the lifting outlet 202 is still positioned inside the alcoholization chamber 1, the materials can be guided and fall onto the top conveyor 103 through the material internal circulation inlet 102. In another embodiment, the lift outlet 202 may be located outside the alcoholization chamber 1, i.e. the material may be poured into the alcoholization chamber 1 from the feeding inlet 101, or may be arranged in parallel with the material distribution cart 301 and the material may be distributed to the alcoholization chamber 1 by the material distribution cart 301.

Preferably, the material elevator 2 may be a vertical elevator. When the material elevator 2 is a vertical elevator, it may be various vertical elevators in the prior art, such as a vertical elevator having a plurality of vertically distributed lifting stages, and the plurality of lifting stages may continuously receive material one by one at the lifting inlet 201, so that the first conveyor may be continuously operated without being suspended while in use. The tipping end of the topping conveyor 103 may also be tipped in a number of ways as the tobacco material is lifted to the lift outlet 202, such as from the material recirculation inlet 102.

The arrangement of the material elevator 2 can realize circulation of the tobacco materials on the plurality of first conveyors in the alcoholization chamber 1, and realize continuous dynamic alcoholization, so that all the tobacco materials can be uniformly heated and wetted in the continuous conveying and falling and loosening processes of the tobacco materials, and the contact uniformity of the tobacco materials and air is further improved. In the prior art, although a plurality of conveyors capable of realizing layer-by-layer blanking are arranged in some alcoholization devices, the materials are conveyed to the conveyor at the last layer and then stopped to be conveyed and stood for alcoholization or directly flow out from a discharge port for other processes, so that the circulation in the alcoholization chamber 1 cannot be realized, and further the uniform alcoholization in the dynamic moving process is difficult to realize. Therefore, compared with the existing standing and stored alcoholization mode in which the warm and humid air can only blow towards the material in the vertical direction, the alcoholization in the dynamic moving process can enable the tobacco material to be contacted with the warm and humid air entering the alcoholization chamber in multiple directions and to be periodically turned over, so that the uniformity of the tobacco material being heated and wetted and contacted with the air is improved, and the alcoholization quality and efficiency can be effectively improved.

As shown in fig. 2, the alcoholization apparatus of the above embodiment further includes a material external circulation system 3, wherein the material external circulation system 3 includes a second conveyor 302 disposed outside the alcoholization chamber 1, and one end of the second conveyor 302 is located at the discharge port 105 of the alcoholization chamber 1 for receiving materials from inside the alcoholization chamber 1, and the other end is located at the feed port 101 of the alcoholization chamber 1 for feeding materials into the alcoholization chamber 1. In the embodiment shown in fig. 2, the second conveyor 302 comprises a plurality of endless sealing conveyors, and at least one of the plurality of sealing conveyors is a climbing sealing conveyor, for example a climbing conveyor feeding the infeed opening 101, so that the tobacco material at the outfeed opening 105 can be lifted from outside the alcoholization chamber 1 to be transported to the infeed opening 101. An end of the second conveyor 302 at the feed opening 101 may be connected to the distribution cart 301, for example, disposed above the distribution cart 301 to feed the distribution cart 301. In fig. 2, the direction of the arrow, i.e. the direction of the outward circulation transportation of the material, is shown, and it can be known from the direction indicated by the arrow that the tobacco material falling from the discharge port 105 is returned to the distribution vehicle 301 after being sequentially diverted by four sealed conveyors.

In the device, the arrangement structure of each circulating part in the alcoholization chamber 1 is compact, and the alcoholization parameter control risk is small; the arrangement of the second conveyor 302 in the material external circulation system 3 is equivalent to the extension of the conveying path of the tobacco material dynamic alcoholization, and each configuration device in the material external circulation system 3 is mature, so that the configuration operation of the second conveyor 302 in the actual production is more flexible and is not limited by space. Moreover, when a large amount of tobacco materials are alcoholized, the arrangement of the material external circulation system can also realize the continuous dynamic alcoholization of the large amount of materials, ensure the uniformity of alcoholization and further improve the efficiency of artificial alcoholization. Meanwhile, because the space inside the alcoholization chamber 1 is limited, if too many layers of first conveyors are arranged or only the materials are broken and crushed due to repeated turning circulation inside the alcoholization chamber 1, the tobacco materials are subjected to external circulation, so that the conveying distance of the materials can be prolonged, and the tobacco materials are prevented from being turned violently for many times.

The heating and humidifying device 303 is used for providing a temperature and humidity environment for the second conveyor 302, the heating and humidifying device 303 can be a heating and humidifying device provided in the prior art, the contact area of the material and the external environment is large due to the long path of the external circulation, and the set temperature and humidity are slightly higher than that of the warm and humid air circulation system 4. In addition, the independently arranged warm and humid air circulation system 4 and the warming and humidifying machine 303 can only start the warm and humid air circulation system 4 during the internal circulation, and can start the warm and humid air circulation system 4 and the warm and humid air circulation system at the same time during the external circulation, thereby being beneficial to saving energy and improving the working efficiency.

In a preferred embodiment, the tobacco alcoholization apparatus may be configured to preset the interval period between the inner circulation and the outer circulation of the tobacco material, for example, the flap gate 203 is controlled to close the discharge port 105, and the flap gate 203 is controlled to close the lifting inlet 201 after the tobacco material is subjected to the inner circulation for a certain period of time in the alcoholization chamber 1, so that the tobacco material flows out from the discharge port 105 to the second conveyor 302 for the outer circulation. In addition, in the actual alcoholization process, an interval period of dynamic cyclic alcoholization and static standing alcoholization can be set, for example, one cycle is performed at intervals of 2-10 days, the time length of each cycle is 2-8 hours, specifically, one cycle alcoholization can be performed at intervals of four days for tobacco lamina alcoholization, and one cycle alcoholization can be performed at intervals of seven days for tobacco stems, and the time length of each cycle is 6 hours.

The tobacco alcoholization apparatus provided in the above embodiment enables the tobacco material to realize double circulation in alcoholization, wherein the double circulation should be understood as warm and humid air circulation and tobacco material circulation. The device for alcoholizing the tobacco material improves the temperature, humidity and aerobic contact uniformity of the tobacco material in the alcoholizing process by the coupling of the circulation of the material internal circulation system in the alcoholizing chamber 1 and the warm and humid air circulation provided by the warm and humid air circulation system 4. Due to the complexity of fluid movement, in the process of providing circulating warm and humid air to the alcoholization chamber 1, the warm and humid air circulating system 4 ensures that the temperature and humidity of each point in the alcoholization chamber 1 are not uniform, and under the condition that the temperature and humidity difference objectively exists, all tobacco materials can equally pass through each point with the temperature and humidity difference through the circulation of the tobacco materials, so that the temperature and humidity in the alcoholization chamber 1 can be equally received by all the tobacco materials in the alcoholization process, and the uniformity of the alcoholization temperature and humidity of the tobacco materials is improved through the interaction of the warm and humid air circulation system and the tobacco material circulation system, particularly through the arrangement of the top conveyor 103, the bottom conveyor 104 and the material elevator 2 (or the second conveyor 302), so that the tobacco materials can turn over when being transported on the conveyors, and the inner-layer materials can randomly take to the outer layer in the turning process, while the outer material will also enter the inner layer, thus balancing the probability of contact between the tobacco material and oxygen. The two circulation systems of the material circulation and the warm and humid air circulation affect each other through coupling interaction, so that the alcoholization conditions are consistent, and the alcoholization quality of the tobacco material is improved.
