AI Technical Summary
Existing technologies are insufficient to effectively reduce the amount of first distillate during the distillation process of baijiu, and traditional methods suffer from limitations in production capacity and are not very effective in reducing the amount of first distillate.
The system employs a first and second condenser connected in series, along with a filter and control valve. By introducing gas during shutdown to expel residual distilled gas from the condenser, the amount of first liquor is reduced.
In actual operation, the amount of first brew can be reduced to 1/5 to 1/10 of the original amount, which improves brewing efficiency and reduces the content of harmful substances.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of alcoholic beverage distillation equipment technology, and in particular to a distillation condenser for reducing the amount of first distillate. Background Technology
[0002] The first distillate (or "head liquor") is the first liquid to flow out during the distillation of baijiu (Chinese white liquor). It has several distinct characteristics: high alcohol content (usually above 60%, sometimes reaching 70%), large bubbles (the bubbles are large but disappear quickly), and rich aroma but also many off-flavors. It may contain significant amounts of methanol, formaldehyde, and other harmful substances, as well as residue from the previous distillation, resulting in a less than ideal taste. Previously, the head liquor was often discarded. However, a requirement for distillation condensers in the brewing process is to reduce the amount of head liquor. Currently, some manufacturers try to reduce the head liquor by decreasing the heat exchange area and increasing the slope of the liquor flow section. However, reducing the heat exchange area has drawbacks, such as limiting production capacity and increasing energy consumption, and its effect on reducing the head liquor is not significant. Therefore, developing a distillation condenser that can reduce the amount of head liquor has significant economic and social benefits. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this invention provides a distillation and condensation device for reducing the amount of first distillate. This reduces the amount of first distillate produced during the alcohol production process.
[0004] To solve the above-mentioned technical problems, the present invention provides a distillation and condensation device for reducing the amount of first-run liquor, comprising a first condenser, a second condenser connected in series with the first condenser, a first control valve disposed on the condensate outlet pipe of the second condenser, an air inlet pipe connected to the condensate outlet pipe between the second condenser and the first control valve, a second control valve disposed on the air inlet pipe, and an air supply mechanism connected to the air inlet pipe.
[0005] As a further improved technical solution, the distillation and condensation device for reducing the amount of first liquor provided by this utility model also includes a filter disposed between the first condenser and the second condenser and connected in series with the first condenser and the second condenser.
[0006] After the previous distillation, the condenser is at a high temperature, containing residual alcohol and water vapor. When the current distillation begins, the alcohol vapor from the previous distillation mixes with the remaining material in the condenser, condensing to produce the first distillate. Through extensive experiments, the applicant discovered that the quantity of the first distillate is significantly affected by the amount of residue left in the condenser from the previous distillation. However, the presence of alcohol or water residue on the condenser surface has little impact on the quantity of the first distillate. The primary influencing factor is the residual distillation gases within the condenser.
[0007] The technical solution provided by this utility model involves adding a purging mechanism to the brewing condenser. When the machine stops, gas is introduced to expel the residual distilled gas in the condenser, reducing the amount of tail liquor remaining in the previous brewing process, thereby reducing the amount of first liquor. In actual operation, the amount of first liquor can be reduced to 1 / 5 to 1 / 10 of the original amount. Attached Figure Description
[0008] The accompanying drawings are provided to further illustrate the present invention and form part of this application, but do not constitute an undue limitation of the present invention. In the drawings:
[0009] Figure 1 This is a schematic diagram of the distillation and condensation apparatus used in the embodiment to reduce the amount of first-run liquor. Implementation
[0010] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0011] like Figure 1 The distillation and condensation apparatus shown for reducing the amount of first liquor includes a first condenser 1, a second condenser 2 connected in series with the first condenser 1, a filter 6 disposed between the first condenser 1 and the second condenser 2, a filter 6 connected in series with the first condenser 1 and the second condenser 2, a first control valve 3 disposed on the condensate outlet pipe of the second condenser 2, an air inlet pipe 4 connected to the condensate outlet pipe between the second condenser 2 and the first control valve 3, a second control valve 5 disposed on the air inlet pipe 4, and an air supply mechanism connected to the air inlet pipe 4.
[0012] The steam inlet of the first condenser 1 is connected to the steam outlet of the distillation vessel using a detachable connection for easy loading and unloading. This distillation condenser, designed to reduce the amount of first distillate, can be used in multiple distillation vessels. The first condenser 1 is a high-temperature condenser, while the second condenser 2 is a low-temperature condenser. The filter 6 removes solids such as lees carried out by the distillation gas.
[0013] After the previous distillation is completed, the steam inlet of the first condenser 1 is separated from the distillation vessel. The first control valve 3 is closed, and the second control valve 5 is opened. Gas generated by the gas supply mechanism is introduced into the second condenser 2 and the first condenser 1. The gas source can be compressed air from an air compressor or high-speed gas from a blower. The introduced gas is discharged from the inlet of the first condenser 1. By introducing gas into the brewing condenser, the residual distillation gas in the condenser is discharged, reducing the amount of tail liquor remaining from the previous brewing process, thereby reducing the amount of first liquor. In actual operation, the amount of first liquor can be reduced to 1 / 5 to 1 / 10 of the original amount.
[0014] Obviously, this utility model is not limited to the preferred embodiments described above. Various modifications and improvements can be made within the spirit of the claims and specification of this utility model to solve the same technical problem and achieve the expected technical effect; therefore, these will not be repeated. All solutions that can be directly or indirectly conceived by those skilled in the art from the disclosure of this utility model, as long as they are within the spirit of the claims, also fall within the protection scope of this utility model.
