Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cigarette processing, in particular to a device for recovering and blending dried leaf shreds, dried head and dried tail leaf shreds. Background Art
[0002] The leaf silk drying process is an important process in the silk making process. Its process tasks are to remove part of the moisture in the leaf silk to meet the processing requirements of the subsequent process; to improve the filling capacity and processing resistance of the leaf silk to achieve the coordination between the two; and to improve and enhance the sensory quality of the leaf silk. Therefore, the moisture content of the leaf silk after drying is a key indicator affecting the quality of winding and sensory quality. However, during the production process of the leaf silk drying machine, at the beginning and end of production or when the equipment stops abnormally due to a fault, due to the small material flow of the leaf silk, the required dehydration amount is less than the actual dehydration capacity of the leaf silk drying machine, and a certain weight of dry head and dry tail leaf silk will inevitably be produced. In actual production, although the weight of the dry head and dry tail leaf silk can be controlled by adjusting the parameters of the leaf silk drying machine, due to the delay in the acquisition of the front and rear feedback signals of the leaf silk drying machine, the lag in the adjustment of the outlet moisture content, and the thermal inertia of the internal environment of the leaf silk drying machine equipment, more dry head and dry tail leaf silk is often produced. In the subsequent rolling process, the dry head and tail leaf shreds are very easy to break due to their poor processing resistance due to their low moisture content, which causes an increase in leaf consumption per box. In addition, the dry head and tail leaf shreds produced under excessively high processing intensity affect the sensory quality of cigarettes.
[0003] At present, there are mainly the following methods for processing the dried head and tail leaf silk in the silk making process:
[0004] (1) Use the parameters of the leaf dryer to adjust and control the weight of the leaf silk at the beginning and end of the dry period, such as lowering the preheating drum wall temperature at the beginning of the material to reduce the conduction of heat energy, or increasing the drum speed and reducing the hot air speed at the end of the material to reduce the residence time of the material in the drum dryer and the conduction of heat energy.
[0005] (2) In the expansion process, the moisture content of the head and tail materials is increased by increasing the steam flow rate.
[0006] (3) Artificially connect the dried head and tail leaves of high-end cigarettes, and then downgrade them and artificially mix them back.
[0007] Among the above three methods, method (1) has a limited adjustable range of leaf shreds machine parameters, and the weight of the dried leaf shreds at the beginning and end is limited, and the leaf shreds with a lower moisture content are still produced in the later process, which increases the crushing and deteriorates the sensory quality; method (2) has a limited water addition capacity in the expansion process (2%-3%), and the drying process is mainly a heat conduction effect. Therefore, the limited water addition to the beginning and end materials does not significantly reduce the weight of the dried leaf shreds at the beginning and end, and it is easy to cause erroneous feedback from the leaf shreds machine program; method (3) has no effect on the sensory quality of high-end cigarettes, but the downgrading and back-mixing of leaf shreds with a lower moisture content will inevitably lead to an increase in the crushing of low-end cigarettes, still causing the loss of raw materials and increasing labor.

The utility model has a clear structure, is easy to manufacture, occupies a small space, and has a significant small-scale humidification effect.
[0034] Embodiment 1:
[0035] See also Figure 1-2 As shown, the utility model is a device for recovering and blending dried leaf shreds at the head and tail of dried leaf shreds, comprising a leaf shred machine 1, the outlet of the leaf shred machine 1 is connected to a first discharging conveyor belt 9 through a first discharging vibration trough 3, the first discharging vibration trough 3 is provided with a first moisture meter 2 and a flap door 4, the lower part of the flip door 4 is provided with a recovery and blending bypass 16, one end of the recovery and blending bypass 16 is connected to the lower part of the flip door 4, and the other end is connected to the first discharging conveyor belt 9; the recovery and blending bypass 16 is provided with a sealed cabinet 6, and a constant temperature and humidity chamber 15 is provided in the sealed cabinet 6. When the humidity of the leaf shreds at the outlet of the leaf shred machine 1 measured by the first moisture meter 2 is less than a set value, the flap door 4 flips, and the leaf shreds enter the sealed cabinet 6 through the recovery and blending bypass 16, are rehumidified by the constant temperature and humidity chamber, and are conveyed back to the first discharging conveyor belt 9 for blending after rehumidification.
[0036] In addition to the original conveyor belt of the dried leaf shreds production line, an additional recovery and blending bypass 16 is added, a sealed storage cabinet 6 is set on the recovery and blending bypass 16, and a constant temperature and humidity chamber 15 is set in the sealed storage cabinet 6.

[0042] The working principle and working process of this utility model:
[0043] When the first moisture meter 2 at the discharge port of the leaf drying machine 1 detects that the moisture content of the material is less than 11%, the flap door 4 of the first discharge vibration trough 3 is opened, the feeding conveyor belt is started 5, and the material enters the sealed storage cabinet 6 with constant temperature and humidity function for moisture rehydration for more than 2 hours, and the treated leaf shreds are mixed back during the production of low-end cigarettes. When low-end cigarettes are produced, the discharge end of the sealed storage cabinet 6 with constant temperature and humidity function is started, and the treated leaf shreds are mixed through the second discharge vibration trough 7 and the second discharge conveyor belt 8 to the first discharge conveyor belt 9 for downgraded mixing.
[0044] In short, the utility model solves the difficult problems of recycling, rehumidifying and blending the dry head and tail leaf shreds produced by the leaf drying machine.
