[0002] The chemical component of alcoholic beverages is alcohol, specifically ethanol. It generally contains trace amounts of fusel oils and esters. The concentration of edible spirits is typically below 60% (a few may exceed 60%). After fractional distillation and purification to over 75%, spirits become medical alcohol; further purification to over 99.5% yields anhydrous ethanol. Alcohol is made from grains through fermentation. my country is one of the earliest countries to brew alcohol, having invented brewing techniques over 2000 years ago. These techniques have been continuously improved and perfected, and the country now produces various concentrations, aromas, and types of alcoholic beverages. Furthermore, it can produce medical alcohol with a concentration of over 95% and anhydrous ethanol with a concentration of 99.99% for industrial, medical, and scientific research purposes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: As attached Figure 1 and attached Figure 2 An alcohol production apparatus is shown, comprising a first distillation kettle 1, a first rectification column 2, a first flavoring basket 3, a second distillation kettle 9, a second rectification column 10, a second flavoring basket 11, and a preheating storage tank 4. The first distillation kettle 1, the first rectification column 2, the first flavoring basket 3, and the preheating storage tank 4 are connected sequentially by pipelines, and the second distillation kettle 9, the second rectification column 10, the second flavoring basket 11, and the preheating storage tank 4 are also connected sequentially by pipelines. The preheating storage tank 4 comprises a preheating kettle 5, a condenser 6, a subcooler 7, and a base 8 arranged sequentially from top to bottom. The first distillation kettle 1, the first rectification column 2, the second distillation kettle 9, and the second rectification column 10... The steam outlets of both are connected to the steam inlets of the preheating kettle 5 and the condenser 6 via two pipes (the two pipes are controlled by valves to open and close respectively). The liquid outlet of the condenser 6 is connected to the inlet of the subcooler 7. The steam generated by the first distillation kettle 1, the first rectification column 2, the second distillation kettle 9, and the second rectification column 10 is first introduced into the preheating kettle 5 to preheat the fermentation liquid. When the temperature reaches 50-60℃, the steam generated by the first distillation kettle 1, the first rectification column 2, the second distillation kettle 9, and the second rectification column 10 is condensed twice by the condenser 6 and the subcooler 7 to produce alcohol. The condenser 6 is a falling film condenser, and the subcooler 7 is a coil condenser. The preheating tank 4 employs a two-stage cooling process. The first stage of this invention uses a falling film condenser, which can use tower water or fermentation liquid to cool the alcohol vapor. The second stage uses a coil cooling system, which utilizes ice water for cooling. This solves the problem of short cooling time in current market equipment that directly uses coil condensers to cool alcohol vapor, increases the volatilization time and space for volatile components, and is more energy-efficient while ensuring the quality of the alcohol.

[0017] The first distillation vessel 1, the first distillation column 2, the first spice basket 3, the second distillation vessel 9, the second distillation column 10, and the second spice basket 11 mentioned above are all mass-produced products on the market and are conventional setups in this field. Therefore, their specific structures and working principles will not be described in detail.

[0018] As one method of distillation: see attached Figure 1 and attached Figure 2 As shown, the preheating kettle 5 is connected to the first distillation kettle 1 and the second distillation kettle 9 through the liquid outlet pipe. After the fermentation broth is preheated by the preheating kettle 5, it enters the first distillation kettle 1 and the second distillation kettle 9 for batch distillation.

[0019] As a second distillation method: see attached Figure 1 and attached Figure 2 As shown, the alcohol production equipment also includes a first preheating heat exchanger 12 and a second preheating heat exchanger 13. The fermentation broth in the preheating kettle 5 is connected to the first preheating heat exchanger 12 and the second preheating heat exchanger 13 via pipes. The first preheating heat exchanger 12 and the second preheating heat exchanger 13 are connected to the first distillation column 2 and the second distillation column 10 via pipes for continuous distillation of the fermentation broth. The outlets of the first distillation column 2 and the second distillation column 10 are connected to the first distillation kettle 1 and the second distillation kettle 9 via pipes. The steam outlets of the first distillation kettle 1 and the second distillation kettle 9 are connected to the first distillation column 2 and the second distillation column 10 via pipes. Both the first distillation column 2 and the second distillation column 10 are connected to the preheating kettle 5 via pipes. Both the first preheating heat exchanger 12 and the second preheating heat exchanger 13 are plate heat exchangers.

[0020] Batch distillation principle: Taking the left distillation section as an example, after the fermentation liquid enters the preheating kettle 5, the corresponding pipes are first controlled by valves to open and close. The steam generated by the first distillation kettle 1 and the first rectification column 2 is introduced into the preheating kettle 5 to heat the fermentation liquid. When the fermentation liquid is heated to 50-60℃, the corresponding pipes are controlled by valves to allow the steam generated by the first distillation kettle 1 and the first rectification column 2 to enter the condenser 6 and the subcooler 7 for secondary condensation and alcohol extraction.

[0021] Continuous distillation principle: Taking the left distillation section as an example, the temperature of the cold liquor entering the preheating kettle 5 is not high. The cold liquor in the preheating kettle 5 is first introduced into the first preheating heat exchanger 12 for further heating. The heated liquid is then introduced into the first rectification column 2. The water and a small amount of alcohol produced in the first rectification column 2 enter the first distillation kettle 1. Excess water is discharged through the level controller in the first distillation kettle 1. The steam produced in the first distillation kettle 1 is introduced into the first rectification column 2 to provide heat. The alcohol vapor produced in the first rectification column 2 is introduced into the condenser 6 and subcooler 7 for secondary condensation to produce alcohol. Continuous distillation utilizes the heat recovery of waste liquid in the kettle, resulting in greater energy savings and allowing for 7... 24-hour continuous production has significantly increased capacity.
