Description

Technical Field

[0001] This utility model relates to the field of liquor brewing technology, and more specifically to an energy-saving device for multi-stage distillation of strong-aroma liquor. Background Technology

[0002] In the field of baijiu (Chinese liquor) brewing technology, distillation is a crucial step in extracting and concentrating flavor compounds. Traditional distillation equipment typically has only one steam outlet, and the pressure and temperature control is not precise enough, making it difficult to effectively separate and extract flavor compounds with different boiling points during distillation. This not only affects the quality and taste of the baijiu but also results in the loss of flavor compounds and waste of energy. Especially in the brewing of strong-aroma baijiu, due to the large variety of flavor compounds with different boiling points, more precise control of the distillation process is required.

[0003] Existing distillation equipment often employs a single distillation condition when extracting flavor compounds with different boiling points, failing to achieve targeted enrichment and control of different flavor compounds. Furthermore, the lack of real-time temperature monitoring and precise pressure control makes it difficult to guarantee the stability and consistency of the distillation process, thus affecting the final quality of the baijiu. In addition, traditional distillation equipment also suffers from low energy utilization efficiency during the condensation process, failing to fully utilize the heat resources in the alcohol vapor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-stage distillation energy-saving device for strong-aroma baijiu. This invention sets up multiple distillation steam outlets and, together with a pressure control system and a temperature control system, adjusts the internal pressure and temperature to achieve the extraction of flavor substances with different boiling points, while also effectively reducing the loss of flavor substances.

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-stage distillation energy-saving device for strong-aroma baijiu, including a distillation tank, with multiple distillation vapor outlets arranged side by side at the upper end of the distillation tank, a main controller installed on the distillation tank, the main controller being electrically connected to a pressure control system and a temperature control system, the pressure control system being used to adjust the pressure inside the distillation tank during distillation, the temperature control system being used to monitor the temperature during the distillation process and to adjust the heating power, thereby extracting different flavor substances, each of the multiple distillation vapor outlets being connected to a condenser assembly through a heat dissipation pipe, and each of the multiple distillation vapor outlets being equipped with a valve, a collection tank being provided on one side of the condenser assembly, the collection tank being equipped with a liquid sampling port, the liquid sampling port being connected to an inspection machine for detecting flavor substances.

[0006] In one preferred embodiment, the pressure control system includes a pressure regulating valve, which is mounted on the distillation tank and electrically connected to the main controller.

[0007] In one preferred embodiment, the temperature control system includes multiple temperature sensors and information transmitters distributed in different areas inside the distillation tank. The information transmitters are used to collect information detected by the multiple temperature sensors and transmit it to the main controller.

[0008] In one preferred embodiment, the heat dissipation pipe includes a conduit, on which spirally wound heat dissipation fins are fixedly sleeved.

[0009] In one preferred embodiment, the condensation assembly includes a water tank, in which a spirally wound condenser tube is fixedly installed. A liquid outlet pipe is fixedly installed at the bottom end of the condenser tube. The liquid outlet pipe passes through the water tank and extends outside the water tank and is located above the collection tank. The two ends of the heat dissipation pipe are respectively connected to the distillation vapor outlet and the top of the condenser tube.

[0010] In one preferred embodiment, the water tank has an inlet at the top and an outlet at the bottom, both of which are equipped with solenoid valves. The inlet is connected to a cold water or room temperature water supply unit, and the outlet is connected to a hot water storage tank, which is connected to a water-using unit.

Simultaneously, temperature sensors monitor the temperature at various points within the distillation column in real time. The main controller automatically adjusts the heating power and condensation rate based on the preset distillation curve and real-time monitoring data, ensuring the stability and consistency of the distillation process. This enables the extraction of flavor substances with different boiling points, effectively reduces the loss of flavor substances, and improves energy utilization efficiency.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0020] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0021] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0022] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] See Figure 1This utility model provides a technical solution: a multi-stage distillation energy-saving device for strong-aroma baijiu, including a distillation tank 1. Multiple distillation vapor outlets 11 are arranged side-by-side at the upper end of the distillation tank 1. A main controller 2 is installed on the distillation tank 1, and the main controller 2 is electrically connected to a pressure control system and a temperature control system. The pressure control system is used to regulate the pressure inside the distillation tank 1 during distillation, and the temperature control system is used to monitor the temperature during the distillation process and adjust the heating power to extract different flavor substances. Each of the multiple distillation vapor outlets 11 is connected to a condenser assembly 4 via a heat dissipation pipe 3, and each of the multiple distillation vapor outlets 11 is equipped with a valve. A collection tank 5 is located on one side of the condenser assembly 4, and the collection tank 5 has a liquid outlet 51. The liquid outlet 51 is connected to a testing machine 6 for detecting flavor substances. This utility model, by setting multiple distillation vapor outlets 11 and cooperating with the pressure control system and temperature control system to regulate the internal pressure and temperature, achieves the targeted enrichment and regulation of flavor substances during distillation, ensuring the stability and improvement of baijiu quality. Meanwhile, the temperature sensor monitors the temperature at various points inside the distillation column in real time. The main controller 2 automatically adjusts the heating power and condensation rate according to the preset distillation curve and real-time monitoring data to ensure the stability and consistency of the distillation process, thereby achieving the extraction of flavor substances with different boiling points, effectively reducing the loss of flavor substances, and improving energy utilization efficiency.

[0025] Preferably, the pressure control system includes a pressure regulating valve, which is installed on the distillation tank 1 and electrically connected to the main controller 2. The pressure regulating valve can be numerical, allowing for intuitive understanding of the specific pressure and precise adjustment to meet the extraction requirements of different flavor compounds under varying pressures.

[0026] Preferably, the temperature control system includes multiple temperature sensors and information transmitters distributed in different areas inside the distillation tank 1. The information transmitters collect information detected by the multiple temperature sensors and transmit it to the main controller 2. The main controller 2 adjusts the heating power to achieve the extraction of flavor compounds at different temperatures.

[0027] Preferably, the heat dissipation pipe 3 includes a conduit, on which spirally wound heat dissipation fins 31 are fixedly sleeved. When the alcohol vapor flows through the conduit, the high temperature transferred to the conduit by the alcohol vapor will be dissipated through the spirally wound heat dissipation fins 31. Therefore, the temperature of the alcohol vapor can be significantly reduced when it flows through the conduit, thereby increasing the condensation rate of the alcohol vapor in the condensation assembly 4.

[0028] Preferably, the condenser assembly 4 includes a water tank 41, inside which a spirally wound condenser tube 42 is fixedly installed. A liquid outlet pipe is fixedly installed at the bottom end of the condenser tube 42, penetrating the water tank 41 and extending outside the water tank 41, located above the collection tank 5. The two ends of the heat dissipation pipe 3 are respectively connected to the distillation vapor outlet 11 and the top of the condenser tube 42. The water tank 41 contains cool or room temperature water. As the alcohol vapor flows through the condenser tube 42, the water cools the vapor and condenses it into liquid distilled spirit. The spirally wound condenser tube 42 prolongs the time the vapor spends in the water tank 41, ensuring that the vapor is completely condensed into liquid distilled spirit.

[0029] Preferably, the water tank 41 has an inlet 43 at the top and an outlet 44 at the bottom. Both the inlet 43 and outlet 44 are equipped with solenoid valves. The inlet 43 is connected to a cold water or room temperature water supply unit, and the outlet 44 is connected to a hot water storage tank 7, which is connected to a water-using unit. This system stores heated water and delivers it to users, providing convenience for daily hot water use. It also effectively recovers and utilizes the heat from the steam, making efficient use of resources.

[0030] Preferably, the distillation tank 1 can also be equipped with an alarm and a fault analyzer, thereby improving the reliability and safety of the equipment.

[0031] The specific control procedures for this device are as follows: Regarding internal pressure, before distillation begins, the pressure inside distillation vessel 1 is typically close to atmospheric pressure, approximately 101.325 kPa (standard atmospheric pressure). During distillation: The pressure can be adjusted within a certain range according to the specific distillation requirements and the desired flavor extraction. To extract flavor substances with different boiling points, the pressure can be controlled within the range of 50 kPa to 200 kPa using a pressure regulating valve. Therefore, when selecting a pressure regulating valve, choose a product with high adjustment accuracy, generally within ±1 kPa, to ensure the stability and consistency of the distillation process.

[0032] Regarding the internal temperature, before heating begins, the temperature inside distillation vessel 1 is typically close to room temperature, approximately 20°C to 30°C. During distillation: depending on the extraction target of flavor substances and the requirements of the distillation process, the temperature can be gradually increased to a range of 60°C to 90°C, or even higher; therefore, the temperature sensor should have high measurement accuracy, generally within ±0.5°C, to ensure precise control of the distillation process.

[0033] Meanwhile, ensure that the alcohol vapor at the outlet of condenser 42 is below the dew point temperature to ensure sufficient condensation within condenser 42. Generally, the inlet temperature of condenser 42 can be set within the range of 20℃ to 40℃. A temperature sensor can be added at the outlet to detect whether the requirements are met, allowing for timely replacement of the cooling water in water tank 41.

[0034] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Modifications and variations made by those skilled in the art that do not depart from the technology and scope of this utility model should be within the protection scope of the appended claims.
