This design not only makes the cooling of the steam more thorough, but also effectively shortens the cooling time and improves production efficiency.

[0020] 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.

[0021] The utility model provides a cooling device for distiller's grains distillation, such as Figure 1-Figure 3 As shown, it includes a primary cooling bin 1, a collecting barrel 2 is provided at the bottom of the primary cooling bin 1 for collecting the distilled liquor, a secondary cooling bin 5 is provided inside the primary cooling bin 1, a cooling pipe 4 is connected to the upper part of the secondary cooling bin 5, the cooling pipe 4 is used for primary cooling, the secondary cooling bin 5 is used for secondary cooling, a discharge pipe 6 is connected to the bottom of the secondary cooling bin 5 for discharging the cooled liquor, a steam pipe 3 is connected to the top of the primary cooling bin 1 for introducing the distilled liquor, an upper header 41 is connected to the upper end of the cooling pipe 4, and a lower header 42 is connected to the lower end of the cooling pipe 4, the upper header 41 is connected to the steam pipe 3, and the lower header 42 is connected to the secondary cooling bin 5, so as to facilitate the top-down transportation of the distilled liquor.

[0022] In this embodiment, a valve 61 is installed on the discharge pipe 6 to facilitate the control of the opening and closing of the discharge pipe 6 .

[0023] Specifically, a serpentine coil 51 is provided inside the secondary cooling bin 5, the top end of the serpentine coil 51 is connected to the lower header 42, and the bottom end of the serpentine coil 51 is connected to the discharge pipe 6. The serpentine coil 51 extends the material conveying distance to ensure sufficient cooling.

[0024] Furthermore, a water inlet 52 is provided on one side of the bottom of the secondary cooling bin 5, a drain outlet 53 is provided on one side of the top of the secondary cooling bin 5, a water pump 54 is installed on the upper part of the interior of the secondary cooling bin 5, the output end of the water pump 54 is connected to the drain outlet 53, and the input pipeline of the water pump 54 is located inside the secondary cooling bin 5. The water inlet 52 and the drain outlet 53 ensure that the secondary cooling bin 5 circulates water in and out, thereby realizing circulating heat exchange of the internal materials.

[0025] Furthermore, the lower header 42 is a funnel-shaped structure, which facilitates the concentrated downward flow of materials.

[0026] Furthermore, the cooling tubes 4 are arranged vertically from top to bottom, and adjacent cooling tubes 4 are arranged at intervals to ensure that the materials are evenly dispersed, thereby improving the heat exchange effect.

[0027] Furthermore, the top opening size of the secondary cooling bin 5 is matched with the width size of the lower header 42 , which facilitates the sealing between the lower header 42 and the secondary cooling bin 5 .

[0028] Furthermore, a water inlet pipe 11 is connected to one side of the bottom of the primary cooling bin 1, and a water outlet pipe 12 is connected to the other side of the upper portion of the primary cooling bin 1, so as to facilitate the entry and discharge of cooling water.

[0029] When the cooling device for distiller's grains distillation of the utility model is used, the high-temperature wine vapor after distillation first enters the upper header 41 through the steam pipe 3, and then is evenly distributed to each cooling pipe 4. Here, the wine vapor undergoes a cooling process, and through contact with the outer wall of the cooling pipe 4, the heat is transferred to the cooling water outside the pipe, and the steam is gradually condensed.

[0030] Subsequently, the condensed liquor is collected through the lower header 42 and flows into the serpentine coil 51 in the secondary cooling bin 5. The liquor is secondarily cooled in the serpentine coil 51. At this time, the water pump 54 works to pump cold water into the secondary cooling bin 5 through the water inlet 52. The cold water exchanges heat with the serpentine coil 51 in the bin, absorbs the heat of the liquor in the coil, and is discharged through the water pump 54 and the drain port 53, forming a cooling water cycle.

[0031] After the wine material is fully cooled in the serpentine coil 51, it is finally collected in the collection bucket 2 through the control of the discharge pipe 6 and the valve 61. In the whole process, the cooling efficiency is greatly improved through the double cooling and the recycling of cooling water, and water resources are also saved.

[0032] In addition, the primary cooling chamber 1 is also equipped with a water inlet pipe 11 and a water outlet pipe 12 for the inlet and outlet of cooling water, ensuring that the cooling water outside the cooling pipe 4 remains at a low temperature to provide a continuous cooling effect.

[0033] 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. The scope of protection of the utility model is defined by the attached claims and their equivalents.
