Description

Technical Field

[0001] This utility model belongs to the technical field of distillation equipment, specifically relating to an air positive pressure atomization and condensation system for distillation equipment. Background Technology

[0002] Traditional distillation processes involve using condensers inside the distillation tower for water or air cooling. The vapors of the spirit enter the tower, condense, and then flow out as spirit. Strict temperature control is crucial at the distillation point; too high a temperature will cause the aroma to dissipate, while too low a temperature will prevent the removal of impurities, leading to discomfort for drinkers. Therefore, the distillation temperature is a critical factor in determining the quality of the spirit. This temperature is primarily determined by condensation, which traditionally employs two methods: air cooling and water cooling. Modern air cooling uses negative pressure, employing axial fans to draw air from above. However, this results in low air pressure, difficulty in control, and poor cooling capacity. Due to variations in regional air humidity and temperature, condensation speed and efficiency differ, leading to variations in spirit quality. To meet the demands of condensation-based spirit production, a practice of not brewing in summer has emerged, as the condensation temperature is often unsuitable, and the cooling process is largely manually regulated. However, this manual control not only affects the yield and quality of the spirit but also increases energy and water consumption during the brewing process.

[0003] Therefore, this application proposes improvements to address the aforementioned issues. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a positive pressure air atomization condensation system for distilled spirits. The purpose of this utility model is to digitize the condensation process by using positive pressure cooling + water ultrasonic atomization technology + Laval tube, and utilizing latent heat of vaporization and heat exchange technology, thereby transforming qualitative experience into quantitative indicators and achieving more reasonable condensation control.

A Laval nozzle is connected to the other side wall of the spirit distillation tower. The Laval nozzle is connected to the corresponding part of the side wall of the spirit distillation tower through a hot air outlet pipe and communicates with the inner cavity of the spirit distillation tower.
