Description

Technical Field

[0001] This invention belongs to the field of vacuum distillation technology, specifically relating to a vacuum distillation apparatus, and more particularly to a honeycomb tube-type low-temperature vacuum distillation apparatus for brewing alcoholic beverages. Background Technology

[0002] Traditional alcoholic beverage distillation employs high-temperature (above 100℃) distillation methods. High temperatures damage the molecular chains in the alcohol, resulting in a harsh and pungent taste in freshly distilled spirits, requiring long-term aging and thawing to repair the damage. This process is time-consuming and costly. Existing vacuum distillation apparatuses often do not fully consider the principles of vacuum mechanics, resulting in thick walls, bulky structures, high material consumption, and high costs. Furthermore, existing vacuum distillation equipment is limited to liquid distillation and cannot process solid-state fermented mash. Moreover, existing vacuum distillation devices typically have only a single vacuum chamber, allowing for extraction at a single temperature. They cannot perform fractional distillation of components with different boiling points within the same apparatus, nor can they achieve parallel extraction at multiple vacuum levels, resulting in poor flexibility and low extraction efficiency. Additionally, in existing equipment, the evaporator and condenser are independently located, requiring steam to be transported from the evaporator to the condenser via long pipelines, leading to significant heat and flavor loss during transport, and requiring a large footprint. Therefore, there is an urgent need for a compact, flexible, low-energy-consumption vacuum low-temperature distillation apparatus that preserves flavor compounds. Summary of the Invention

[0003] (a) Technical problems to be solved The technical problem to be solved by the present invention is to overcome the shortcomings of existing vacuum distillation kettles, such as bulky structure, single function, inability to extract at multiple vacuum degrees in parallel, inability to extract in stages, high energy consumption, and large loss of flavor. The present invention provides a honeycomb tube-type vacuum low-temperature distillation device that realizes integrated evaporation and condensation, flexible switching of functional modes, parallel control of multiple vacuum degrees, and staged collection.

The feed control valve and the drain valve are both located outside the functional tube (2), connected to the feed pipeline and the drain pipeline respectively, and connected to the liquid level detection component for signal connection respectively. When the liquid level detection component detects that the liquid level rises to a preset high threshold, the feed control valve closes to stop feeding and enter the distillation state.

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The following embodiments are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0043] Overall Structure As shown in the attached figures, the honeycomb tube-type vacuum low-temperature distillation apparatus of the present invention includes a vacuum condensation chamber 1, a functional tube array 2, a functional sealing end cap 3, a vacuum control system 4, an evaporation control system 5, a liquid level control system 6, and a segmented collection system 7.

[0044] The vacuum condensation chamber 1 is welded from stainless steel and has a honeycomb structure. The side plates 12 of the vacuum condensation chamber 1 are provided with multiple pre-cut welding grooves 14. The functional tubes 2 are welded to the side plates 12 from the outside of the equipment through the pre-cut welding grooves 14, forming a honeycomb arrangement and completely sealed independent spaces. The interior of the vacuum condensation chamber 1 is equipped with partitions 11, which divide the interior of the vacuum condensation chamber 1 into multiple independent vacuum chambers. Each vacuum chamber is sealed and isolated from the others by the partitions 11, preventing air exchange. A vacuum interlayer exists between the vacuum condensation chamber 1 and the functional tubes 2, forming a heat insulation barrier. The chamber wall of the vacuum condensation chamber 1 is also provided with annular reinforcing ribs 13 to further enhance its ability to resist vacuum negative pressure. The bottom of the vacuum condensation chamber 1 is equipped with support feet to support the entire device.

[0045] The functional tube array 2 consists of multiple straight pipes arranged in a honeycomb pattern, located inside the vacuum condensing chamber 1 and distributed throughout each vacuum chamber. These pipes can be round, conical, or irregularly shaped. Each tube array forms an independent space to hold the fermented material or liquor to be distilled. The inner wall of the functional tube array 2 is in contact with the fermented material or liquor. Steam escaping from the fermented material or liquor enters the vacuum condensing chamber 1, contacts the outer wall of the functional tube array 2, and condenses into distilled liquor. The functional tube array 2 also serves as a structural support for the vacuum chamber, supporting the vacuum condensing chamber 1 to resist the negative vacuum pressure.

[0046] Functional sealing end caps 3 are respectively located at the interface of the vacuum condensing chamber 1 and both ends of the functional tube 2. They are fixedly connected to the port of the functional tube 2 via quick-connect chuck welding end 22, and detachably connected to the vacuum condensing chamber 1 via quick-connect chuck, ensuring the airtightness of the vacuum chamber, while facilitating the loading and unloading of fermentation materials or wine, and also serving as maintenance ports. The functional sealing end caps 3 include an evaporation end cap 31, a condensation end cap 32, a solid end cap 33, and a conventional end cap 34, used to realize liquid distillation, condensation, solid distillation, and conventional sealing functions, respectively. The functional sealing end caps 3 are provided with multiple conventional interfaces 37 for installing conventional accessories such as pipes, valves, sensors, and instruments. Figure 3-1 to Figure 3-4As shown, each functional tube 2 can be independently switched to solid distillation mode, evaporation mode or condensation mode by installing different functional sealing end caps, and the functional modes of each functional tube 2 can be freely combined.

[0047] The vacuum control system 4 is connected to the vacuum condensing chamber 1 and is used to independently evacuate and control the vacuum level of each vacuum chamber. The vacuum control system 4 includes multiple vacuum pumps 41, with one independent vacuum pump 41 corresponding to each vacuum chamber. Each vacuum pump 41 operates independently, controlling the vacuum level of its corresponding vacuum chamber. Each vacuum chamber is equipped with an independent vacuum level sensor, and each vacuum pump 41 independently adjusts the vacuum level of its corresponding vacuum chamber based on the detection signal from the corresponding vacuum level sensor. The gas-liquid mixture generated during evaporation is discharged through the vacuum pump 41. The vacuum control system 4 also includes an air solenoid valve 44, which is located on the drive air pipeline of the vacuum pump 41 and is used to control the on / off of the drive air to control the start and stop of the vacuum pump 41. A slow-opening valve 55 is installed on the evacuation pipeline between the vacuum control system 4 and the vacuum condensing chamber 1. The slow-opening valve 55 is a slow-opening type and is used to open after reaching a preset temperature to delay vacuum establishment and prevent boiling over.

[0048] The evaporation control system 5 is connected to the functional tubes 2 and is used to control the heating temperature within the functional tubes 2. Each functional tube 2 can have its temperature curve set independently, i.e., the temperature change over time; the temperature curves of each functional tube 2 are independent of each other. The evaporation control system 5 includes a heat transfer oil electric heating tube 51, a heat transfer oil storage tube 38, and a circulation pump 56. The heat transfer oil electric heating tube 51 is mounted on the evaporation end cap 31 and extends into the functional tube 2. The heat transfer oil electric heating tube 51 is an electric heating element; when energized, it generates heat, which is transferred to the liquid via the heat transfer oil in the heat transfer oil storage tube 38, achieving indirect heating. The heat transfer oil storage tube 38 is connected to the outside environment, and the oil fumes generated during heating are discharged outside the equipment. The circulation pump 56 is connected to the functional tubes 2 and is used to drive the circulation of the liquid within the functional tubes 2, ensuring uniform heating of the liquid. The wine temperature control system 54 and the heat transfer oil temperature control system 53 jointly control the start and stop of the heat transfer oil electric heating tube 51. The temperature detection end of the wine temperature control system 54 is located inside the functional tube 2. Each functional tube 2 can be heated independently according to a preset temperature curve. The heating rate, holding temperature and cooling rate can all be set independently, forming a temperature matrix extraction structure.

[0049] The liquid level control system 6 is connected to the functional tube 2 and is used to detect and control the liquid level of the wine inside the functional tube 2. The liquid level control system 6 adopts a batch control logic of high-stop, low-drain, and restart, that is, when the liquid level rises to the high level, feeding stops; when it drops to the low level, the residual liquid is drained; and after draining, the next batch of feeding is automatically triggered. The detection end of the liquid level detection component is located inside the functional tube 2, or it is connected to the functional tube 2 through an external liquid level pipe and led out to the outside of the vacuum condensation chamber 1.

[0050] The segmented collection system 7 is connected to the output of the functional tube array 2 or the output of the vacuum machine 41. Through a multi-channel time controller circuit group 71, the distillation products output from each vacuum chamber are sequentially segmented and collected in time order. Each liquid solenoid valve 72 switches sequentially at preset time nodes, achieving the classified collection of different fractions to the segmented receiving container 73. Multiple vacuum chambers and the segmented collection system 7 form a three-dimensional matrix extraction structure. Each vacuum chamber can be set with different vacuum and temperature curves. The segmented collection system 7 performs multi-segmented collection of the distillation products output from each vacuum chamber under different temperature curves and vacuum conditions. Through the combination of different temperatures, different vacuum levels, and different fractions, three-dimensional matrix extraction is achieved in the same batch of distillation. Example 1 (Liquid Distillation) During liquid distillation, the liquor in the evaporation tube 2 is indirectly heated under vacuum via the heat-conducting oil electric heating tube 51. The circulation pump 56 drives the liquor to circulate, ensuring uniform heating and generating saturated steam. The steam enters the condensation tube 2 via the vapor-liquid pipeline group 46, then passes through the stainless steel corrugated pipe 35 into the tube interior. After exchanging heat with the low-temperature liquor contained in the tube, the steam exits the tube and enters the vacuum condensation chamber 1. It is then discharged through the vacuum machine 41 into the segmented collection system 7 for segmented collection according to time sequence. Each vacuum chamber can be set with different vacuum levels and temperature curves. The segmented collection system 7 performs multi-segmented collection of the distillation products output from each chamber, forming a three-dimensional matrix extraction structure.

[0051] Example 2 (Solid-state distillation) During solid-state distillation, the solid end cap 33 is installed at the bottom port of the functional tube 2, and the solid mash is loaded into the solid functional tube 2 from the top. When the functional tube 2 is a conical tube, its lower inner diameter is larger than its upper inner diameter to facilitate the discharge of solid materials. The saturated vapor generated in the evaporation functional tube 2 under vacuum enters from the bottom of the solid functional tube 2 through the vapor-liquid pipeline group 46, passes through the solid mash, and exchanges heat with the mash, causing the distillate in the mash to evaporate. The vapor is discharged from the top of the solid functional tube 2, enters the vacuum condenser chamber 1, and is discharged into the segmented collection system 7 by the vacuum machine 41 for segmented collection in chronological order. After distillation, the mash is discharged from the bottom. Example 3 (End Cap Switching and Function Combination) Each functional tube 2 can independently switch between functional modes and can be freely combined. For example... Figure 3-1 to Figure 3-4 As shown, in the same apparatus, some tubes are equipped with solid end caps 33 to function as solid-state distillation tubes, some tubes are equipped with evaporation end caps 31 to function as evaporation heating tubes, and some tubes are equipped with condensation end caps 32 to function as condensation tubes for steam condensation. The functional modes of each tube can be freely combined to achieve multi-mode parallel operation. Example 4 (Multi-temperature control system collaborative operation and batch liquid level control) The evaporation control system 5 includes a liquor temperature control system 54 and a heat transfer oil temperature control system 53, which work together. The liquor temperature control system 54 and the heat transfer oil temperature control system 53 jointly control the start and stop of the heat transfer oil electric heating tube 51. An AC contactor circuit group 52 is used to control the start and stop of the heat transfer oil electric heating tube 51. The temperature detection terminal of the liquor temperature control system 54 is located inside the functional tube 2, monitoring the temperature changes inside the tube in real time. Each functional tube 2 can be heated independently according to a preset temperature curve; the heating rate, holding temperature, and cooling rate can all be set independently. When the liquor temperature rises to the set value, the AC contactor circuit group 52 disconnects, and the heat transfer oil electric heating tube 51 stops heating; simultaneously, the slow-opening valve 55 opens, and a vacuum slowly enters the functional tube 2. Then, as the vacuum develops, the liquor temperature gradually decreases. After reaching the set value, the AC contactor circuit group 52 closes, the heat transfer oil electric heating tube 51 restarts heating, and simultaneously, the slow-opening valve 55 closes, stopping the vacuuming process and entering the heating state, thus repeating the cycle.

[0052] The liquid level control system 6 monitors the liquid level in the functional tube 2 in real time via a liquid level signal sensing circuit. During the liquid feeding stage, the liquid feeding pump 63 starts, and the liquor enters the functional tube 2. When the liquid level rises to the preset high threshold, the reed switch float valve 65 activates, the liquid feeding pump 63 closes, and the feeding stops, and the device enters a closed distillation state. During the distillation stage, when the liquid level slowly drops to the preset low threshold, the liquid discharge pump 64 starts, discharging the small amount of residual liquid remaining in the functional tube 2 into the discharge container 66. After emptying is completed, the liquid discharge pump 64 closes, the system resets, and automatically triggers the next round of feeding. Example 5 (Extended Polygonal Honeycomb Structure) The honeycomb structure of vacuum condenser chamber 1 is a honeycomb lattice structure, with each lattice unit welded and sealed. This structure is also suitable for the distillation of other alcoholic beverages such as rice wine and fruit wine. Example 6 (Structure of heat transfer oil electric heating tube) A heat transfer oil electric heating tube 51 is installed on the evaporation end cap 31 and extends into the functional tube 2. The heat transfer oil electric heating tube 51 is an electric heating element; when energized, it generates heat, which is transferred to the wine liquid via the heat transfer oil in the heat transfer oil storage tube 38, achieving indirect heating. The heat transfer oil storage tube 38 is connected to the outside environment. A circulation pump 56 is connected to the functional tube 2, driving the wine liquid to circulate within the tubes, ensuring sufficient heat exchange between the wine liquid and the heat transfer oil electric heating tube 51, resulting in a uniform temperature distribution. The evaporation end cap 31 is equipped with a heat transfer oil storage tube 38, which is connected to the heat transfer oil expansion tube 39 via a stainless steel corrugated pipe 57 to buffer the volume changes caused by the thermal expansion and contraction of the heat transfer oil. Example 7 (Switching the end cap during solid distillation) Solid-state fermentation material is loaded into the solid-state functional tube 2 through the installation of solid-state end caps 33, realizing solid-state distillation mode. The installation and removal of end caps facilitates the loading and unloading of solid-state fermentation material, while ensuring the airtightness of the tubes during the distillation process. Example 8 (Low-temperature cooking of grain raw materials for brewing) The device can also be used as a low-temperature cooking equipment. The grain raw materials for brewing are loaded into the functional tube array 2, and heated to 35℃~95℃ by the evaporation control system 5. The grain is then cooked at low temperature under vacuum negative pressure, allowing the starch to fully gelatinize, facilitating subsequent saccharification and fermentation. This low-temperature cooking method avoids the damage to the nutritional components of the grain caused by high-temperature cooking and reduces energy consumption. Example 9 (Vacuum distillation extraction of whole plant) The device can also be used for vacuum distillation extraction of whole plants. The whole plant is placed in the functional tube 2, and distillation extraction is carried out under vacuum negative pressure and 35℃~95℃ conditions to collect the volatile active ingredients in the plant, achieving low-temperature extraction and preserving the plant's active ingredients.
