Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a heating device for tobacco sugar. Background Technology

[0002] In the cigarette manufacturing process, sugar is added to the tobacco leaves. This sugar mainly consists of sugars, tobacco extract, and flavorings. Spraying the sugar evenly onto the leaves allows them to absorb the liquid, improving the aftertaste, masking impurities, enhancing the aroma, and improving the physical properties of the tobacco. Because the sugar contains sugar, it has a high viscosity and contains many impurities. Therefore, the sugar needs to be heated to ensure its fluidity, prevent blockage of the filling structure, and improve the absorption of the sugar by the tobacco leaves.

[0003] In the industry, steam pipes are commonly used to heat sugar syrups, resulting in rapid heating. However, due to the physical properties of steam, issues such as excessive preheating temperature and temperature fluctuations in the sugar syrup can occur. Excessive steam temperature can lead to caramelization of the sugar syrup, which requires disposal and results in significant waste.

[0004] Patent document CN215494738U discloses a self-circulating constant temperature control device for tobacco syrup, including a syrup pipeline, a water supply pipeline, a steam coil, a preheating pipeline, a circulation pipeline, a syrup tank, a hot water tank, a pneumatic actuator, a one-way variable pump, a stirring motor, a temperature sensor, a ball valve, and a PLC controller. It achieves stable preheating and heating of the syrup through water bath heating. This prior art converts steam heat into hot water heat before using the hot water to heat the syrup. While this improves the temperature stability of the syrup, it also suffers from a slow heating rate. Utility Model Content

Detailed Implementation

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] A heating device for tobacco sugar, such as Figure 1 As shown, the system first includes a sugar container 1. The sugar container 1 includes an outer shell and an inner shell, with an external heating chamber 11 formed between the outer and inner shells, and a liquid storage chamber 12 formed within the inner shell. Simultaneously, a filter barrel 121 is provided within the liquid storage chamber 12, further dividing the liquid storage chamber 12 into a coarse sugar chamber located within the filter barrel 121 and a fine sugar chamber located between the filter barrel 121 and the inner shell. The inlet of the sugar container 1 communicates with the coarse sugar chamber, and the outlet communicates with the fine sugar chamber. The filter barrel 121 is further configured as follows: the filter barrel 121 includes a first shell with a larger outer diameter and a second shell with a smaller outer diameter. The first and second shells each have openings, and the opening of the first shell communicates with the corresponding opening of the second shell through a connecting pipe, forming a filter hole 121a within the connecting pipe. The opening of the first shell and the opening of the second shell are respectively the outlet and inlet of the filter hole 121a. The space between the outer walls of the first shell, the second shell, and the connecting pipe is hollow, forming an internal heating chamber 121b. By introducing a heat source with a temperature that meets the heating requirements of the sugar into the outer heating chamber 11 and the inner heating chamber 121b, the sugar can be heated from both inside and outside, resulting in a fast heating speed.

[0025] In some embodiments, the inner shell is provided with a plurality of filter barrels 121, which are sequentially nested together. The outer diameters of each filter barrel 121 increase sequentially with the central axis of the sugar tank 1 as their central axis. The innermost filter barrel 121 with the smallest outer diameter is connected to the inlet of the sugar tank 1; the cavity between the outermost filter barrel 121 with the largest outer diameter and the inner shell is connected to the outlet of the sugar tank 1. The arrangement of the plurality of filter barrels 121 can, on the one hand, increase the number of filtrations of the sugar, further improving the quality of the sugar; on the other hand, it also forms a plurality of internal heating chambers 121b within the liquid storage chamber 12, further increasing the heating rate.

[0026] In some embodiments, the filter cartridge 121 is detachably disposed within the liquid storage chamber 12 to facilitate cleaning of the filter cartridge 121. The detachable connection is not limited to any particular embodiment; in some embodiments, such as... Figure 1 As shown, the top of the outer shell and the top of the inner shell are connected by a ring plate. The filter barrel 121 is provided with an overlapping plate 121c that overlaps the ring plate, achieving a detachable connection through overlapping. When multiple filter barrels 121 are provided, the overlapping plates 121c of several filter barrels 121 are overlapped sequentially. To improve the stability of the overlap, the distance between the outer shell and the inner shell, i.e., the ring diameter of the ring plate, can be larger to increase the overlap area. If necessary, support feet can also be provided at the bottom of the filter barrel 121, with the support feet abutting against the inner wall of the inner shell. In some embodiments, a limiting groove can be provided on the ring plate, and a limiting block that can be inserted into the limiting groove can be provided on the overlapping plate 121c. The installation stability is improved through the cooperation of the limiting groove and the limiting block.

[0027] In some implementations, to improve heating uniformity, such as Figure 1 As shown, the filter tank 121 is equipped with a stirring device 14. The stirring device 14 drives the sugar in the coarse sugar chamber to flow and heat it evenly. At the same time, based on the function of the filter hole 121a, the shear force of the stirring device 14 can also be transferred to the sugar in the fine sugar chamber, so that it flows and heats it evenly.

[0028] Since the filter barrel 121 also serves a filtering function, in some embodiments, the stirring device 14 includes stirring blades 141 suspended inside the filter barrel 121 and scraper 142 abutting against the inner wall of the filter barrel 121. Both the stirring blades 141 and the scraper 142 are mounted on a rotating shaft, which is connected to the motor output shaft via a reducer. The stirring blades 141 perform the stirring function, while the scraper 142 can scrape off the sugar adhering to the wall of the filter barrel 121, preventing the adhering sugar from blocking the filter holes 121a and affecting the flow of the sugar.

[0029] In some embodiments, an insulation shell is also provided outside the outer shell, and an insulation cavity 13 is formed between the insulation shell and the outer shell. The insulation cavity 13 is filled with insulation material to reduce heat loss and ensure heating efficiency.

[0030] The heating device for tobacco sugar also includes a hot water tank 2, which is used to introduce hot water at a temperature that meets the heating requirements of the sugar into the outer heating chamber 11 and the inner heating chamber 121b. Water has a large specific heat capacity, which can improve the heating stability of the sugar.

[0031] Both the outer heating chamber 11 and the inner heating chamber 121b of the sugar tank 1 are circulatedly connected to the hot water tank 2. In some embodiments, the outer heating chamber 11 and the inner heating chamber 121b of the sugar tank 1 can be circulatedly connected to the hot water tank 2 separately. In other embodiments, the hot water tank 2 includes an outlet and an inlet. The outlet is connected to the outer heating chamber 11, and the inlet is connected to the inner heating chamber 121b. The outer heating chamber 11 and the inner heating chamber 121b are connected, so that the outer heating chamber 11, the inner heating chamber 121b, and the hot water tank 2 are sequentially connected. In this sequential connection, the hot water in the hot water tank 2 is first sent to the outer heating chamber 11 and then enters the inner heating chamber 121b, so that the temperature of the outer heating chamber 11 is slightly higher than that of the inner heating chamber 121b, thereby forming a temperature gradient from the outside to the inside, which is beneficial to heat transfer and further improves the heating speed.

[0032] In order to control the temperature of the hot water in hot water tank 2, such as Figure 1 As shown, the hot water tank 2 is equipped with a heat transfer coil 21 and a cold water straight pipe 22. The heat transfer coil 21 is used for heating, and the cold water straight pipe 22 is used for cooling, together adjusting the temperature of the hot water in the hot water tank 2.

[0033] A heat transfer coil 21 is spirally wound around a cold water straight pipe 22, with a gap between the heat transfer coil 21 and the cold water straight pipe 22. The heat transfer medium can be steam, hot air, etc. The cold water straight pipe 22 has several cold water outlets along its length, which are evenly arranged sequentially along the length of the cold water straight pipe 22. In use, the hot water tank 2 is filled with water. Heat transfer medium is introduced into the heat transfer coil 21 to exchange heat with the water in the hot water tank 2, thereby heating the water into hot water. When the water temperature is too high, cold water is introduced into the cold water straight pipe 22. The cold water is sprayed out from the several cold water outlets to mix with the hot water and evenly cool the hot water.

[0034] After the heat medium in the heat medium coil 21 exchanges heat with the water, although the temperature of the heat medium is reduced, there is still residual heat. In some embodiments, a conduit 131 is provided in the insulation cavity 13. The heat medium coil 21 includes a heat medium inlet and a heat medium outlet. The heat medium outlet is connected to the conduit 131 to send the heat medium with residual heat into the insulation cavity 13 to improve the insulation effect.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
