Description

Technical Field

[0001] This utility model relates to a curing barn that facilitates air distribution and preserves the aroma of tobacco leaves, belonging to the field of curing barn technology. Background Technology

[0002] In existing tobacco curing barns, humidification and heating are typically carried out simultaneously during the curing process, with continuous dehumidification achieved through exhaust fans. This causes the tobacco aroma to continuously escape with the airflow during curing, resulting in a weakening of the aroma in the finished tobacco leaves. Furthermore, most existing curing barns have heating coils installed on the ground, relying on side wall vents to create a large-volume hot air circulation, which further exacerbates the loss of aroma components.

[0003] Therefore, there is a need for a new curing barn structure that can optimize airflow distribution and reduce aroma loss in order to improve the preservation of tobacco aroma. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a curing barn that facilitates air distribution and preserves the aroma of tobacco leaves, thereby optimizing airflow distribution within the barn, reducing aroma loss, and improving the preservation of tobacco aroma. This overcomes the shortcomings of existing technologies.

[0005] The objective of this utility model is achieved through the following technical solution: This utility model discloses a curing barn that facilitates air distribution and preserves the aroma of tobacco leaves. It includes a curing barn body, a tobacco loading chamber within the curing barn body, a tobacco hanging rack within the tobacco loading chamber, and a hot air inlet and outlet on the heat-insulating wall in the middle of the curing barn body. Absorbent cotton cloth is arranged along the longitudinal direction of the curing barn body on the upper part of the tobacco loading chamber. A slider that can move back and forth repeatedly along the longitudinal direction of the curing barn body is located on the upper side of the tobacco loading chamber. The slider is connected to a driving device. A water scraping device for scraping water off the absorbent cotton cloth and a water collection trough for collecting water are provided on the slider. The water collection trough is connected to a water guide trough that discharges water to the outside of the curing barn body. An external discharge pipe connected to the water guide trough is located outside the curing barn body.

[0006] The aforementioned squeegee is a clamp that holds the upper and lower sides of the absorbent cotton cloth.

[0007] The absorbent cotton fabric mentioned above consists of two layers arranged alternately.

[0008] The aforementioned driving device includes a fixed guide rod and a lead screw arranged along the longitudinal direction of the oven body, the slider is located on the lead screw, and a drive motor is provided on the outside of the lead screw.

[0009] As described above, there are two sliders arranged symmetrically on the left and right sides. Each slider is installed on a corresponding lead screw, and the drive motor is installed on one of the lead screws. A sprocket is provided between the outer ends of the left and right lead screws.

[0010] As mentioned above, a water-sealing elbow and a water-stop valve are installed on the external drainage pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the distributed arrangement of water-absorbing cotton cloth scraping devices, helps to distribute airflow. That is, the airflow blows downward through the gaps between the water-absorbing cotton cloth scraping devices, which improves the uniformity of the airflow of the scraping device in the curing barn. At the same time, during the tobacco curing process, the moisture produced by the tobacco leaves is absorbed by the water-absorbing cotton cloth scraping devices, and then discharged outside the curing barn through the scraping device, the water collection trough scraping device, the water guide trough scraping device, and the external drainage pipe scraping device. This avoids the need for strong airflow to remove moisture later, greatly reduces the loss of aromatics, and better preserves the aroma of the tobacco leaves.

[0012] 2. By moving the slider squeegee, the squeegee can scrape off the water on the absorbent cotton cloth. Specifically, the gap between the clamping squeegee and the clamping plate squeegee is small. During the movement, it can clamp the absorbent cotton cloth that has expanded due to water absorption or is relatively fluffy. As the clamping squeegee moves, the water absorbed by the absorbent cotton cloth will fall and be collected by the water collection tank squeegee.

[0013] 3. The absorbent cotton cloth wiper device consists of two layers arranged in an alternating pattern, which further facilitates airflow.

[0014] 4. The slider wiper unit consists of two symmetrically arranged pieces, each mounted on a corresponding screw-type wiper unit. The drive motor wiper unit is mounted on one of the screw-type wiper units. A sprocket wiper unit is located between the outer ends of the left and right screw-type wiper units. This sprocket wiper unit facilitates synchronous and unidirectional movement of the two screw-type wiper units. Furthermore, only one motor-driven wiper unit is required, which helps reduce costs.

[0015] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0025] like Figures 1-7As shown, this utility model discloses a curing barn that facilitates air distribution and preserves the aroma of tobacco leaves. It includes a curing barn body 1, a tobacco loading chamber 2 within the body 1, a tobacco hanging rack within the loading chamber 2, and a hot air inlet 3 and an air outlet 4 on the heat-insulating wall in the middle of the body 1. Absorbent cotton cloth 5 is arranged along the longitudinal direction of the curing barn body 1 on the upper part of the loading chamber 2. The two ends of the absorbent cotton cloth 5 are fixed to transverse fixing rods located on the front and rear sides of the loading chamber 2. A slider 6, which can move back and forth repeatedly along the longitudinal direction of the curing barn body 1, is located on the upper side of the loading chamber 2. The slider 6 is connected to a driving device, and a scraping device 7 for scraping water off the absorbent cotton cloth 5 is provided on the slider 6. The water collection trough 8 is connected to the water guide trough 9 that discharges water to the outside of the curing barn body 1. An external discharge pipe 10 connected to the water guide trough 9 is provided outside the curing barn body 1. This structure, through the distributed water-absorbing cotton cloth 5, helps to distribute the air, that is, the wind blows down through the gaps between the water-absorbing cotton cloth 5, which can improve the uniformity of the wind force in the curing barn body 1. At the same time, during the tobacco curing process, the moisture produced by the tobacco leaves is absorbed by the water-absorbing cotton cloth 5, and then discharged outside the curing barn through the water scraper 7, the water collection trough 8, the water guide trough 9 and the external discharge pipe 10, avoiding the need for a large wind to remove the moisture later, greatly reducing the loss of aromatics and better preserving the aroma of the tobacco leaves.

[0026] Furthermore, the squeegee 7 consists of clamping plates 11 that hold the upper and lower sides of the absorbent cotton cloth 5. With this structure, the movement of the slider 6 can drive the squeegee 7 to scrape off the water on the absorbent cotton cloth 5. Specifically, the gap between the clamping plates 11 is small, and during the movement, it can clamp the absorbent cotton cloth 5, which is swollen from absorbing water or is relatively fluffy. As the clamping plates 11 move, the water absorbed by the absorbent cotton cloth 5 will fall and be collected by the water collection tank 8.

[0027] Furthermore, the absorbent cotton cloth 5 consists of two layers arranged in an alternating pattern, which further facilitates airflow.

[0028] Furthermore, the driving device includes a fixed guide rod 12 and a lead screw 13 arranged along the longitudinal direction of the oven body 1. The slider 6 is located on the lead screw 13, and a drive motor 14 is provided on the outside of the lead screw 13. Specifically, a collar that is sleeved with the fixed guide rod 12 is provided on the slider 6. With this structure, the forward and backward movement of the slider 6 can be controlled by the rotation of the lead screw 13.

[0029] Furthermore, the sliders 6 are arranged symmetrically on the left and right, and each slider 6 is mounted on a corresponding lead screw 13. The drive motor 14 is mounted on one of the lead screws 13. A sprocket 15 is provided between the outer ends of the left and right lead screws 13. This sprocket 15 facilitates the synchronous and unidirectional movement of the two lead screws 13. At the same time, only one motor 14 is needed, which also helps to reduce costs.

[0030] Furthermore, a water-sealing elbow 16 and a water-stop valve are provided on the external drain pipe 10, so that the water-sealing elbow 16 can help prevent hot air and other substances from escaping outward.

[0031] When dehumidification is required, the drive motor 14 is started, the lead screw 13 rotates, and the slider 6 on it moves back and forth. During the movement, the clamp 11 on the slider 6 scrapes the water from the absorbent cotton cloth 5 and it enters the water collection trough 8 set on the slider 6. The water collection trough 8 connects with the water guide troughs 9 set on the left and right side walls of the drying chamber body. The upper end of the water guide trough 9 is open and the water guide trough 9 is closed on the outside of the drying chamber body 1. Then it connects with the external drain pipe 10. The water guide trough 9 is set at an angle, which is conducive to introducing water into the drain end and draining it through the external drain pipe 10. This can reduce the situation of dehumidification by strong wind.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
