Description

Technical Field

[0001] The utility model relates to the field of tobacco processing, in particular to a cigar core pretreatment device. Background Art

[0002] As the most central part of the cigar, the cigar core occupies most of the entire cigar and is the key to determining the taste of the cigar. In the production process of traditional handmade cigar cores, whole tobacco leaves of different varieties are used in proportion to form a unique cigar flavor. Cigar core pretreatment is an important process before the cigar core tobacco leaves are rolled, mainly to achieve the loosening and rehydration of the whole tobacco leaves. In China, the current method of pretreatment of cigar cores is mainly to manually lay the tobacco leaves on a horizontal surface and then rehydrate the tobacco leaves through a sprayer. This method is not only inefficient, but also difficult to ensure the uniformity of the moisture content of the tobacco leaves. In the production process of cigarette silk, although there is a loosening and rehydration device, the whole cigar tobacco leaf is larger in volume and lower in moisture content than the flue-cured tobacco leaf. When loosening and rehydrating, the rake nails of the roller are easy to damage the tobacco leaves and entangle them on the rake nails, and it is difficult to achieve the effect of loosening and rehydrating the whole cigar tobacco leaf. Utility Model Content

[0003] The utility model aims to design a cigar core pretreatment device in order to solve the problems in the existing cigar core pretreatment process.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] The utility model provides a cigar core pretreatment device, comprising a tobacco leaf uniformity device, a roller, a water adding system, a steam nozzle, a tobacco leaf output device, and a PLC; the tobacco leaf uniformity device is arranged at the front end of the roller, and is responsible for sending the tobacco leaves into the roller after loosening, the inlet end of the roller is higher than the outlet end, the steam nozzle is arranged on the steam pipe at the inlet of the roller, the tobacco leaf output device is arranged behind the roller, and the tobacco leaves that have been subjected to moisture conditioning treatment are transported to the downstream process, and the water adding system is connected with the PLC.

[0006] As a preferred embodiment of the present invention, the tobacco leaf uniformity device is a first vibrating conveyor.

[0007] As a preferred embodiment of the present invention, the inner wall of the drum is provided with a plurality of guide plates staggeredly distributed on the drum wall along the axial direction of the drum.

[0008] As a preference of the present utility model, the water adding system includes a primary water adding system and a secondary water adding system. The primary water adding system includes a primary water adding nozzle, a primary water adding pipeline, and a primary water adding diaphragm valve; the secondary water adding system includes a secondary water adding nozzle, a secondary water adding pipeline, a secondary water adding solenoid valve, and a water adding pump. The primary water adding system is installed at the front end inside the drum, and the secondary water adding system is installed at the end inside the drum. The primary water adding nozzle is installed at the front end inside the drum and is controlled by the primary water adding diaphragm valve through the primary water adding pipeline. The secondary water adding nozzle is installed at the end inside the drum and is controlled by the secondary water adding solenoid valve through the secondary water adding pipeline. The primary water adding system controls the opening degree of the diaphragm valve and the solenoid valve in the water adding pipeline through the PLC to add water in a fixed proportion to achieve the primary moisture regain of the tobacco leaves. The secondary water adding system obtains the moisture content of the tobacco leaves at the outlet of the drum through the PLC, and uses PID control to control the frequency of the water adding pump and the solenoid valve in the water adding pipeline to achieve the secondary precise water adding and moisture regain of the tobacco leaves.

[0009] As a preference of the present utility model, the primary water adding system further includes an inlet moisture infrared detector arranged at the inlet of the drum to detect the moisture content of the tobacco leaves processed by the tobacco leaf uniform device.

[0010] As a preference of the present utility model, the secondary water adding system further includes an outlet moisture infrared detector arranged at the outlet of the drum to detect the moisture content of the moisture regained tobacco leaves conveyed out of the drum.

[0011] As a preference of the present utility model, a compressed air nozzle is further installed in the middle of the drum. The compressed air nozzle in the middle of the drum periodically blows the tobacco leaves attached to the inner wall of the drum to prevent some tobacco leaves from adhering to the inner wall for a long time, resulting in uneven water addition. By blowing air onto the inner wall, the tobacco leaves are made to fall off the inner wall, reducing the tobacco leaves adhering to the inner wall, and performing another loosening and moisture regain.

[0012] As a preference of the present utility model, the compressed air nozzle adopts two nozzles with an included angle of 180 degrees and is fixed on a stainless steel compressed air pipe along the axis of the drum.

[0013] As a preference of the present utility model, a second vibrating conveyor is further arranged at the outlet end of the drum.

[0014] When the equipment operates, the drum first starts to preheat, the steam nozzle is opened to make the temperature inside the drum reach the set value; the tobacco leaves are conveyed onto the first vibrating conveyor to start the loosening process of the tobacco leaves; when the tobacco leaves enter the drum, the primary water adding nozzle performs the first fixed ratio water addition to the tobacco leaves through steam ejection; when the tobacco leaves are conveyed to the middle of the drum, the compressed air nozzle performs intermittent blowing to further loosen and moisture regain the tobacco leaves; when the tobacco leaves are conveyed to the end of the drum, the second feedback water addition is performed to the tobacco leaves.

[0015] The guide plates on the inner wall of the drum are distributed along the axial direction of the drum. There is a certain interval between each guide plate, and they are staggeredly distributed on the entire drum wall. The guide plates on the drum wall can further loosen the tobacco leaves and avoid damage to the tobacco leaves caused by the rake nails and entanglement on the rake nails.

[0016] The beneficial effects of the present utility model are as follows: By installing compressed air nozzles on the cylinder body, the moisture regain of the tobacco leaves can be made more uniform and the loosening effect is better. By replacing the rake with guide plates on the drum wall, damage to the tobacco leaves is avoided. Two water additions are adopted. The first water addition is in a fixed ratio to quickly regain the moisture of the tobacco leaves, and the second water addition is controlled by PID to achieve precise control of the water addition to the tobacco leaves, making the moisture regain effect better. By pre-treating the cigar filler with this device, not only the efficiency is improved, but also the loosening and moisture regain effects are better. Brief Description of the Drawings

[0026] The following will describe in detail the specific embodiments of the present utility model with reference to the figures.

[0027] As shown in the attached Figure 1-2As shown in the figure, this embodiment provides a pre-treatment device for cigar filler, which includes a first vibrating conveyor 1, a deflector 2, a compressed air nozzle 3, a steam diaphragm valve 4, a compressed air solenoid valve 5, a steam nozzle 6, a primary water addition nozzle 7, a secondary water addition nozzle 8, a secondary water addition solenoid valve 9, a water pump 10, a primary water addition diaphragm valve 11, a drum 12, an inlet moisture infrared detector 13, and an outlet moisture infrared detector 14. The vibrating conveyor 1 is installed at the inlet of the drum 12. The compressed air pipe extends into the interior of the drum 12 through the inlet of the drum 12, and a compressed air solenoid valve 5 is installed on the pipeline. The compressed air nozzle 3 is installed on the compressed air pipe inside the drum 12. The steam nozzle 6 is installed on the steam pipeline at the inlet of the drum, and a steam diaphragm valve 4 is installed on the steam pipeline. The deflectors 2 are evenly and staggeredly installed on the inner wall of the drum 12. The primary water addition nozzle 7 is installed at the inlet of the drum, and a primary water addition diaphragm valve 11 is installed on the primary water addition pipeline. A secondary water addition nozzle 8 is installed above the outlet of the drum 12. The opening and closing of the water addition function are realized through the secondary water addition solenoid valve 9 on the secondary water addition pipeline, and the water pump 10 realizes the precise control of water addition.

[0028] During the operation of the equipment, the cigar filler tobacco leaves are conveyed to the first vibrating conveyor 1. After the tobacco leaves are loosened, they enter the interior of the drum 12. When the tobacco leaves enter the interior of the drum 12, the temperature inside the drum 12 is kept constant by controlling the opening degree of the steam diaphragm valve 4. At the same time, the primary water addition diaphragm valve 11 is controlled to add water to the tobacco leaves in a fixed proportion for the first time. Under the action of the rotation of the deflector 2 and the drum 12, the tobacco leaves are gradually conveyed to the end of the drum 12. When the tobacco leaves are conveyed to the middle position of the drum 12, the compressed air nozzle 3 blows the inner wall of the drum 12, so that the tobacco leaves are loosened inside the drum 12 and fully contact and absorb the applied water. At the same time, under the action of the compressed air blowing, the tobacco leaves adhering to the inner wall of the drum 12 are also blown off, ensuring the uniformity of water addition. When the tobacco leaves enter the end of the drum 12, the secondary water addition solenoid valve 9 is opened. By obtaining the moisture content of the inlet moisture infrared detector 13 and the outlet moisture infrared detector 14, the water pump 10 is controlled by using a PLC controller and PID regulation method to adjust the water addition amount of the secondary water addition, so as to realize the precise control of water addition to the cigar filler tobacco leaves. The fully rehumidified tobacco leaves leave the drum 12 and enter the second vibrating conveyor 15 to be conveyed to the subsequent processes.

[0029] As a preferred embodiment of the present invention, the compressed air nozzle 3 is fixed on a stainless steel compressed air pipe along the axis of the drum by using two nozzles with an included angle of 180 degrees.

[0030] As a preferred embodiment of the present invention, a second vibrating conveyor 15 is further provided at the outlet end of the drum 12.

[0031] Although the present invention has been described herein with reference to illustrative embodiments thereof, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited by the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
