Abstract

[0002] In the wine production process, distillation is a crucial link, which can effectively purify and concentrate alcohol, thereby obtaining high-quality wine products. However, the traditional single distillation technology has limited the improvement of wine quality to a certain extent. In the single distillation process, due to the limitations of distillation time and temperature, it may not be possible to fully extract and separate the effective ingredients in the lees, resulting in the taste and aroma quality of the wine not being optimal.
[0003] Existing single-shot distillation devices can usually only perform one distillation operation and cannot perform multiple consecutive distillation and purification of the lees. This means that after one distillation, many valuable components still remain in the lees and cannot be effectively extracted and utilized. This not only reduces the overall quality of the wine, but also causes a waste of resources.
[0004] In addition, the heat and steam generated during the single distillation process are usually not fully utilized, which also reduces energy efficiency. At the same time, the single distillation has limited effect on the separation of complex components in the lees, which may result in a high impurity content in the final product, affecting the purity and taste of the wine. Utility Model Content
[0005] The purpose of the utility model is to provide a multiple distillation device for wine lees, so as to solve the problem that the existing single distillation device mentioned in the above background technology can usually only perform one distillation operation, and cannot perform multiple continuous distillation and purification on the wine lees. This means that after one distillation, there are still many valuable components remaining in the wine lees, which cannot be effectively extracted and utilized. This not only reduces the overall quality of the wine, but also causes the problem of waste of resources.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a device for multiple distillation of wine lees, such as Figure 1-Figure 3 As shown, it includes a distillation tower and a cooling tower. The distillation tower includes a primary distillation tower 1 and a secondary distillation tower 3. The cooling tower includes a primary cooling tower 2 and a secondary cooling tower 6. The top of the primary distillation tower 1 is connected to the top of the primary cooling tower 2 through a primary riser 4, the bottom of the primary cooling tower 2 is connected to the top of the secondary distillation tower 3, and the top of the secondary distillation tower 3 is connected to the top of the secondary cooling tower 6 through a secondary riser 7. The exteriors of the primary distillation tower 1 and the secondary distillation tower 3 are both connected with a steam inlet pipe 5. The double distillation and cooling ensure a high purity, so that the effective components in the lees can be more fully extracted and separated.
[0023] In this embodiment, one end of the steam inlet pipe 5 is divided into a first branch pipe 41 and a second branch pipe 42. The end of the first branch pipe 41 is connected to the air inlet of the primary distillation tower 1, and the end of the second branch pipe 42 is connected to the gas supply pipe 31 of the secondary distillation tower 3 to facilitate the entry of steam.
[0024] Specifically, a water inlet pipe 21 is connected to the lower side of the primary cooling tower 2, a water outlet pipe 22 is connected to the upper side of the primary cooling tower 2, a plurality of branch pipes 23 are arranged on the upper part of the primary cooling tower 2, the bottom ends of the branch pipes 23 are connected to the primary riser 4, a plurality of vertical heat exchange tubes 24 are arranged in the middle of the primary cooling tower 2, the tops of the heat exchange tubes 24 are connected to the upper header 241, the bottoms of the heat exchange tubes 24 are connected to the lower header 242, and the bottoms of the lower header 242 are connected to the cooling bin 25, so as to exchange heat with the cooling water in the primary cooling tower 2, thereby reducing the temperature of the wine and allowing it to be initially cooled.
[0025] Furthermore, a circulating water inlet 251 is provided on the outer side of the cooling bin 25, and a serpentine tube 26 is provided inside the cooling bin 25. The serpentine tube 26 extends the descending distance of the wine material, thereby increasing the cooling time. The top end of the serpentine tube 26 is connected to the lower collecting pipe 242, and the bottom end of the serpentine tube 26 is connected to the inner cylinder of the secondary distillation tower 3 to facilitate sufficient cooling.
[0026] Furthermore, an inner pot liquid level gauge 33 is installed on the outer wall of the inner cylinder of the secondary distillation tower 3, and an outer pot liquid level gauge 32 is installed on the outer wall of the outer cylinder of the secondary distillation tower 3, so as to facilitate liquid level monitoring.
[0027] Furthermore, an exhaust pipe 34 is installed on the top of the secondary distillation tower 3, and the outer end of the exhaust pipe 34 is connected to the secondary riser 7 to facilitate the discharge of the secondary distilled wine.
[0028] Furthermore, a thermometer and a barometer are installed at the top of the inner cylinder of the secondary distillation tower 3 to facilitate the monitoring of the air pressure and temperature of the secondary distillation.
[0029] Furthermore, the heat exchange tubes 24 are arranged at equal intervals in the longitudinal direction to ensure that the wine is evenly dispersed, thereby ensuring rapid cooling.
[0030] When the lees multiple distillation device of the utility model is used, the lees are first placed in the primary distillation tower 1, and then steam is introduced into the primary distillation tower 1 through the steam inlet pipe 5. With the heating of the steam, the alcohol and other volatile components in the lees are distilled out, and the steam carries these components through the primary riser 4 into the primary cooling tower 2.
[0031] In the primary cooling tower 2, the distilled steam is diverted to each heat exchange tube 24 through the diverter pipe 23, and heat is exchanged with the cooling water entering from the water inlet pipe 21 to achieve preliminary cooling. The cooled wine is collected by the lower header 242 and flows into the serpentine pipe 26 in the cooling bin 25 to further increase the cooling time and effect.
[0032] After the primary cooling, the liquor flows into the secondary distillation tower 3 through the serpentine pipe 26 for secondary distillation. During the secondary distillation process, steam is continuously introduced into the secondary distillation tower 3 through the steam inlet pipe 5 to distill and purify the liquor again. The steam after the secondary distillation carries higher purity alcohol and other components through the secondary riser 7 and enters the secondary cooling tower 6 for further cooling.
[0033] During the whole process, the internal environment of the secondary distillation tower 3 is monitored in real time by a thermometer and a barometer, and the liquid level is monitored by an inner pot liquid level meter 33 and an outer pot liquid level meter 32 to ensure the stability of the distillation process.
[0034] Ultimately, the wine after double distillation and double cooling has higher purity and quality, effectively extracting and separating the effective ingredients in the lees.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
