Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, and in particular to a distillation apparatus for determining the content of volatile acids. Background Technology

[0002] The main components of wine include water, ethanol, volatile acids, sugars, and other substances. Acetic acid is the primary volatile acid, and its content is an important indicator of the chemical stability of wine. In small amounts, acetic acid contributes to the aroma and flavor of wine, giving it complexity and freshness. However, excessively high levels of acetic acid produce a pungent vinegar smell. Furthermore, abnormally high acetic acid levels may indicate instability, such as microbial contamination or excessive oxidation. Therefore, acetic acid content testing is necessary in wine production.

[0003] Acetic acid in wine is an organic acid that can neutralize with alkalis. It is typically titrated using a standard sodium hydroxide solution. When the acetic acid in the solution is completely neutralized, the amount of sodium hydroxide consumed can be used to calculate the acetic acid content. Before titrating wine, distillation is usually used to remove components that may affect the titration. The conventional method is to use an alcohol lamp for heating and distillation; however, this method results in slow heating of the wine and low distillation efficiency. Utility Model Content

[0004] In view of this, the present invention aims to provide a distillation apparatus for determining the content of volatile acids, so as to improve distillation efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A distillation apparatus for determining the content of volatile acids includes a chassis, and a heating container, a condenser, and a steam pipe disposed on the chassis;

[0007] The heating container is used to hold the wine; the condenser pipe is connected to the heating container; the outlet end of the steam pipe is inserted into the heating container, which can pass water vapor into the wine to heat and condense the wine, and the condenser pipe can receive the steam emitted by the heating container and condense the steam.

[0008] Furthermore, the heating container has a first chamber and a second chamber;

[0009] The first chamber is used to hold the wine; the second chamber is connected to the upper part of the first chamber and is connected to the condenser tube; the second chamber is filled with anti-boiling agent and the steam pipe extends into the first chamber.

[0010] Furthermore, the connection between the second chamber and the first chamber expands to form an expansion cavity.

[0011] Furthermore, a drain pipe is provided at the bottom end of the condenser tube;

[0012] The drain pipe is provided with an upward-extending branch pipe that connects to the outside, in order to balance the air pressure inside and outside the drain pipe.

[0013] Furthermore, the branch pipe is filled with a plurality of filler fragments to prevent liquid from entering the branch pipe from the drain pipe, and there are gaps between the filler fragments.

[0014] Furthermore, the chassis includes a support platform, a waste liquid pipe is provided on the support platform, and a valve is provided on the waste liquid pipe;

[0015] The distillation apparatus also includes a fixing assembly for securing the heating container to the support platform;

[0016] The bottom of the heating container is provided with a drain port, which is connected to the inlet of the waste liquid pipe.

[0017] Furthermore, the fixing component includes a pressure plate and fasteners;

[0018] The heating container has a radially protruding flange at the drain port. The pressure plate presses the flange onto the waste liquid pipe, and the pressure plate is fastened to the support platform by the fastener.

[0019] Furthermore, the fixing assembly also includes an elastic pad sandwiched between the pressure plate and the flange.

[0020] Furthermore, the pressure plate is provided on each side of the protruding edge.

[0021] Furthermore, the distillation apparatus also includes a mounting assembly disposed on the chassis;

[0022] The heating container and / or the condenser tube are fixedly connected to the mounting assembly.

[0023] Furthermore, the mounting assembly includes a bracket fixed to the chassis and elastic bands fixed at both ends to the bracket;

[0024] The heating container or the condenser tube is pressed against the support by the elastic band.

[0025] Compared with the prior art, this utility model has the following advantages:

[0026] The distillation apparatus for determining the volatile acid content of the present invention uses a steam pipe to pass water vapor into the wine for heating. The water vapor does not affect the total acetic acid content of the solution after distillation, so it does not affect the final determination of acetic acid. At the same time, the high-temperature water vapor heats the wine quickly, and the distillation speed is also faster, which can improve the distillation efficiency of the wine.

[0027] Secondly, the design includes a first chamber and a second chamber, with the second chamber filled with an anti-bumping agent. This prevents the liquid in the first chamber from boiling violently and rushing into the subsequent condenser after rapid heating by steam. An expansion chamber further buffers any liquid that enters during the boiling process. A branch pipe ensures pressure balance inside and outside the drain pipe, allowing the condensed liquid to be discharged normally.

[0028] Furthermore, filling the branch pipe with filler fragments can prevent excessive liquid from flowing into the branch pipe when a large amount of condensate enters the outlet pipe. The support platform and fixing components effectively secure the heating vessel, and the waste liquid pipe with a valve allows the user to easily drain residual liquid from the heating vessel after distillation. The combination of pressure plates and fasteners firmly secures the heating vessel and facilitates installation. The inclusion of elastic pads prevents direct contact between the pressure plate and the flange, reducing the flange's risk of damage and extending the lifespan of the distillation apparatus.

[0029] Furthermore, the presence of a pressure plate on each side of the flange provides a more balanced clamping force, enhancing the clamping effect. The mounting assembly allows for the installation of the heating element and condenser coil onto the chassis. Using elastic bands to secure the heating element or condenser coil to the bracket prevents them from easily coming loose or being damaged. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0054] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] This embodiment relates to a distillation apparatus for determining the content of volatile acids, in order to improve distillation efficiency.

[0056] In terms of overall structure, combined Figures 1 to 3 As shown, the distillation apparatus for determining the volatile acid content in this embodiment includes a housing 1, and a heating container 2, a condenser 3, and a steam pipe 4 disposed on the housing 1.

[0057] Heating container 2 is used to hold the wine. Condenser 3 is connected to heating container 2. The outlet end of steam pipe 4 is inserted into heating container 2, which can pass water vapor into the wine to heat and condense the wine. Condenser 3 can receive the steam emitted from heating container 2 and condense the steam.

[0058] As set up above, the distillation apparatus for determining the volatile acid content in this embodiment uses steam pipe 4 to pass water vapor into the wine for heating. The water vapor does not affect the determination of acetic acid in the solution after distillation. At the same time, the high-temperature water vapor heats the wine quickly, and the distillation speed is also faster, which can improve the distillation efficiency of the wine.

[0059] Based on the above overview, please refer to... Figures 1 to 3 As shown, specifically, the casing 1 is a box structure with an opening on one side, and the heating container 2 and the condenser pipe 3 are installed inside the casing 1. The top of the heating container 2 is provided with a plug pipe 204, and the end of the plug pipe 204 is provided with an external thread. One end of the steam pipe 4 is connected to the steam generating equipment, and the other end passes through the side wall of the casing 1 and enters the heating container 2 through the plug pipe 204, and is connected to the heating container 2 through a threaded joint.

[0060] In this embodiment, the heating container 2 has a first chamber 201 and a second chamber 202. The first chamber 201 is used to hold the wine. The second chamber 202 is connected to the upper part of the first chamber 201 and is connected to the condenser pipe 3. The second chamber 202 is filled with an anti-bumping agent 5, and the steam pipe 4 passes through the first chamber 201. When high-temperature steam rapidly heats the wine, it can cause the wine to become superheated. Superheated liquid is unstable. If the external temperature of the superheated liquid suddenly drops sharply or bubbles or impurities enter, it will boil violently with a popping sound. This phenomenon is called bumping. By setting up the first chamber 201 and the second chamber 202, and filling the second chamber 202 with the anti-bumping agent 5, the wine in the first chamber 201 will not bump into the condenser pipe 3 after being rapidly heated and boiled by steam.

[0061] Specifically, the anti-bumping agent 5 uses glass fragments. The microstructure of these glass fragments has many small pores or gaps on its surface, which contain air. During heating, this air escapes as small bubbles, thus providing a vaporization nucleus for the liquid, allowing it to boil steadily and preventing bumping. Of course, the anti-bumping agent 5 can also be made of zeolite, ceramic chips, or one or more other materials.

[0062] Secondly, in order to further reduce the impact of bumping, the connection between the second chamber 202 and the first chamber 201 is expanded to form an expansion chamber 2021. The expansion chamber 2021 can provide a buffer space for the gas and liquid gushing out from the first chamber 201 to reduce the impact on the anti-bumping agent 5 in the second chamber 202.

[0063] In this embodiment, the first chamber 201 is spherical, the upper part of the second chamber 202 is a vertically upward-extending cylinder, and the expansion cavity 2021 at the bottom is spherical. The anti-bumping agent 5 is disposed in the cylindrical part of the second chamber 202. The heating container 2 is also provided with a liquid addition pipe 205, which connects to the first chamber 201 and extends obliquely upward, with external threads at the pipe opening. The user can add liquid into the heating container 2 through the liquid addition pipe 205 and seal the opening of the liquid addition pipe 205 with a threaded cap.

[0064] Regarding the connection structure between the heating container 2 and the casing 1, the casing 1 in this embodiment includes a support platform 101, on which a waste liquid pipe 7 is provided, and a valve 701 is provided on the waste liquid pipe 7. The distillation apparatus also includes a fixing component 8 for fixing the heating container 2 to the support platform 101. The bottom end of the heating container 2 is provided with a drain port 203, which is connected to the inlet of the waste liquid pipe 7. The support platform 101 and the fixing component 8 can effectively fix the heating container 2, and the waste liquid pipe 7 with valve 701 allows the user to easily drain the residual liquid in the heating container 2 after distillation.

[0065] The fixing component 8 includes a pressure plate 801 and a fastener 802. The heating container 2 has a radially protruding flange 206 at the drain port 203. The pressure plate 801 presses the flange 206 onto the waste liquid pipe 7, and the pressure plate 801 is fastened to the support platform 101 by the fastener 802. The combination of the pressure plate 801 and the fastener 802 securely fixes the heating container 2 and facilitates installation. In this embodiment, the fastener 802 is a combination of a stud and a wing nut. One end of the stud is fastened to the support platform 101, and the other end is screwed with a wing nut, which presses the pressure plate 801 downwards. Alternatively, the fastener 802 can also be a bolt, which can be directly fastened to the support platform 101, and the pressure plate 801 can be tightened with a nut.

[0066] Preferably, the fixing component 8 further includes an elastic pad 803 sandwiched between the pressure plate 801 and the flange 206. The elastic pad 803 prevents the pressure plate 801 from directly contacting the flange 206, while ensuring sufficient contact between the elastic pad 803 and the flange 206, making the flange 206 less prone to damage and thus improving the service life of the distillation apparatus. In this embodiment, the elastic pad 803 is a rubber elastic pad, fitted onto the heating container 2.

[0067] Preferably, a pressure plate 801 is provided on each of the radial sides of the drain port 203. Providing a pressure plate 801 on each radial side of the drain port 203 ensures a more balanced clamping force on the protruding edge 206, thus improving the clamping effect. In this embodiment, the pressure plate 801 is a long strip with a notch conforming to the outer wall of the heating container 2, enabling it to firmly clamp the protruding edge 206.

[0068] Furthermore, as a further means of securing the heating container 2, the distillation apparatus also includes a mounting assembly 9 mounted on the casing 1, with the heating container 2 fixedly connected to the mounting assembly 9. The second chamber 202 of the heating container 2 is relatively long, and the mounting assembly 9 can fix the relative position of the second chamber 202 of the heating container 2 to the casing 1, making the heating container 2 less prone to shifting during use and resulting in more stable performance.

[0069] Specifically, the mounting component 9 includes a bracket 901 fixed to the chassis 1, and elastic bands 902 fixed at both ends to the bracket 901. The heating container 2 is pressed against the bracket 901 by the elastic bands 902. Using the elastic bands 902 to press the heating container 2 or the condenser tube 3 against the bracket 901 prevents the heating container 2 or the condenser tube 3 from easily coming loose, and also prevents damage to the heating container 2 or the condenser tube 3. In this embodiment, the bracket 901 is fixed inside the chassis 1, and the part in contact with the heating container 2 conforms to the outer wall of the heating container 2. The elastic band 902 is a rubber band, and bolts and washers are used to press both ends of the rubber band against the bracket 901.

[0070] Regarding the specific structure of the condenser tube 3, in this embodiment, the condenser tube 3 is a serpentine condenser tube 3. A drain pipe 301 is provided at the bottom of the condenser tube 3, and a branch pipe 302 extending upwards and connecting to the outside is provided on the drain pipe 301 to balance the air pressure inside and outside the drain pipe 301. The branch pipe 302 ensures that the air pressure inside and outside the drain pipe 301 is balanced, allowing the liquid condensed by the condenser to be discharged normally from the drain pipe 301. The cold water inlet and outlet pipes of the condenser tube 3 both pass through the casing 1 and connect to the water supply equipment. A graduated liquid receiving container 10 is placed below the drain pipe 301.

[0071] Furthermore, the branch pipe 302 is filled with multiple filler fragments 6 to prevent liquid from entering the branch pipe 302 from the drain pipe 301, and there are gaps between the filler fragments 6. Filling the branch pipe 302 with filler fragments 6 ensures that even when a large amount of liquid condenses and enters the drain pipe, the liquid will not excessively flood into the branch pipe 302. In this embodiment, the filler fragments 6 are broken glass, and the top of the branch pipe 302 is provided with a funnel structure to facilitate the filling of the filler fragments 6 into the branch pipe 302.

[0072] Similarly, in this embodiment, the condenser tube 3 is also fixed in the chassis 1 by the mounting assembly 9. The mounting assembly 9 is provided in two sets along the length of the condenser tube 3, which can better fix the condenser tube 3.

[0073] The distillation apparatus for determining the volatile acid content in this embodiment uses a steam pipe 4 to pass steam into the wine for heating. The steam does not affect the determination of acetic acid in the distilled solution. At the same time, the high-temperature steam heating speed is fast, and the wine distillation speed is also fast, which can improve the distillation efficiency of the wine.

[0074] As an example of usage, in specific implementation, 10 ml of wine can be added to the heating container 2, and steam can be continuously introduced until 100 ml of solution is discharged from the drain pipe 301 to the receiving container 10. At this time, the ethanol and acetic acid in the wine are basically completely distilled. The components of the distilled solution are water, ethanol, acetic acid and a very small amount of impurities. Then, the solution is boiled and the acetic acid content is determined by titration with sodium hydroxide solution.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
