Description

Technical Field

[0001] The present invention relates to an evaporation kettle, in particular to a fruit wine de-alcoholization kettle for separating ethanol in fruit wine from the original fruit wine solution. Background Art

[0002] Non-alcoholic fruit wine retains the original nutritional components, color, aroma, taste and flavor of ordinary fruit wine while being alcohol-free, and is a new type of non-alcoholic beverage. During the production process of non-alcoholic fruit wine, an evaporator is required to separate ethanol from the original fruit wine solution to obtain an alcohol-free beverage. CN 118995358 A discloses a production method of non-alcoholic fruit wine. This method realizes the production of non-alcoholic fruit wine through an evaporation device, specifically including the following steps: Step 1: By controlling the extension of the telescopic rod, the hollow frustum is used to block the evaporator, and then the air in the evaporator and the secondary evaporation box is extracted through the steam outlet. In the present invention, through the setting of the conical ring, when the fruit wine enters the interior of the evaporator, under the shielding effect of the conical ring, the fruit wine will contact the inner wall of the evaporator. During the process of the fruit wine falling along the inner wall of the evaporator, the fruit wine can be in full contact with the inner wall of the evaporator, so that the fruit wine can directly receive the heat from the inner wall of the evaporator, and then the fruit wine can be quickly heated, ensuring the efficiency of heat conduction, and further enabling the alcohol to be effectively volatilized. This patent application also discloses an evaporator for producing non-alcoholic fruit wine. However, since the interior of this evaporator is a hollow cylinder, and there are multiple arc-shaped scrapers in the cylinder, the fruit wine is distributed to the inner wall of the evaporator by the rotation of the arc-shaped scrapers, which makes the fruit wine not flow along a specified route in the evaporator. In order to completely separate the alcohol in the fruit wine, the evaporator can only adopt an intermittent batch operation method, that is, let the fruit wine stay in the evaporator for heating to separate the alcohol, and then discharge the remaining liquid material from the evaporator at one time, and cannot achieve continuous evaporation operation of continuously inputting the alcohol-containing liquid and continuously outputting the alcohol and the non-alcoholic liquid.

Since at least one stirring fin is fixed on the outer conical surface of each bottomed cone plate, and the stirring fin is a trapezoidal plate protruding from the outer conical surface of the bottomed cone plate along the radial direction of the bottomed cone plate, the liquid containing alcohol can be fully stirred in each stage of the return flow channel, and the liquid containing alcohol is in more sufficient contact with the fixed cone plate group and the rotating cone plate group, with better heat exchange effect and more conducive to alcohol separation. Since the fixed cone plate group is a combined fixed cone plate group, a plurality of positioning pin rods arranged at equal angular intervals are provided between the upper support plate and the lower support plate, an annular positioning plate is welded on the outer edge of the fixed cone plate, positioning pin holes corresponding to the positions and numbers of the positioning pin rods are opened on the annular positioning plate, and a spacing tube is sleeved on the positioning pin rods between adjacent annular positioning plates, which makes the production, assembly, inspection and maintenance of the fixed cone plate more convenient. Since the rotating cone plate group is a combined rotating cone plate group, a cone plate shaft is provided between the bearing installed on the upper support plate and the bearing installed on the lower support plate, a spacing sleeve matched with the cone plate shaft is provided at the bottom of the rotating cone plate, the cone plate shaft is a prismatic shaft, and the spacing sleeve is a sleeve with a prismatic center hole matched with the prismatic shaft. While facilitating the production, assembly and inspection of the rotating cone plate group, it realizes the rotation of all bottomed cone plates driven by one driving motor and one prismatic shaft, so as to stir each stage of the return flow channel simultaneously. Since a heating jacket is provided on the outer wall of the middle kettle body, and a hot water pipe and a cold water pipe are provided on the outer wall of the heating jacket, the heating effect of the middle kettle body on the liquid in the kettle is better.

[0014] As Figure 1As shown in the figure, the fruit wine de-alcoholization kettle of the present invention includes a de-alcoholization kettle composed of an upper kettle body 1, a middle kettle body 2, and a lower kettle body 3 connected in series. The upper kettle body includes an upper cylinder 15, and an upper cylinder flat cover 14 that closes the upper end of the upper cylinder is provided at the upper end of the upper cylinder. The lower kettle body includes a lower cylinder 12, and a bottom plate cover 13 that closes the lower end of the lower kettle body is provided at the lower end of the lower cylinder. The middle kettle body includes a middle cylinder 21. Connecting flanges for connecting with the upper cylinder and the lower cylinder are provided at the upper and lower ends of the middle cylinder. A heater 33 for heating the materials in the kettle is provided in the lower kettle body. A lower support plate 32 is provided at the bottom of the middle kettle body. A plurality of axial through holes 11 for communicating the lower kettle body and the middle kettle body with each other are provided on the lower support plate. An upper support plate 17 is provided at the top of the middle kettle body. The upper support plate is fixed on the upper flange of the middle kettle body. The upper support plate also serves as the upper sealing cover plate of the middle kettle body. A fixed cone plate group and a rotating cone plate group are provided between the upper support plate and the lower support plate. The fixed cone plate group is composed of a plurality of bottomless cone plates 22 with a large upper opening and a small lower opening of the same specification arranged at equal intervals along the axial direction of the middle kettle body. The rotating cone plate group is composed of a plurality of bottomed cone plates 23 with a large upper opening and a small lower opening of the same specification arranged at equal intervals along the axial direction of the middle kettle body. The cone angles of the bottomless cone plates and the bottomed cone plates are equal and they are arranged alternately along the axis direction of the middle kettle body, so as to form a multi-stage return flow channel inside the middle kettle body. A straight cylinder retaining ring 27 is provided at the outer edge of each bottomless cone plate. The height of the straight cylinder retaining ring is less than the distance between adjacent fixed cone plates. The diameter of the straight cylinder retaining ring is larger than the outer diameter of the bottomed cone plate, so as to form an exhaust ring gap 26 at the highest point of each stage of the return flow channel, through which the alcohol gas separated from the return flow channel enters the annular space 29 between the straight cylinder retaining ring and the inner wall of the middle kettle body. A driving motor 16 for driving the rotating disk group to rotate around the axis of the middle kettle body is provided in the upper kettle body above the upper support plate. The driving motor preferably uses an explosion-proof motor. Rotating cone plate group installation bearings are provided on the upper support plate and the lower support plate.

[0016] Preferably, an alcohol-containing liquid lower injection pipe 6 is provided in the middle of the middle kettle body. A vacuum extraction pipe is also provided in the upper part of the middle kettle body. Vacuum extraction of the kettle can reduce the boiling point of alcohol, so that alcohol can boil at a lower temperature, thereby reducing the temperature inside the kettle body during the de-alcoholization process and preventing the flavor of the fruit wine after de-alcoholization from changing due to excessive temperature.

[0017] Preferably, at least one stirring fin 24 is fixed on the outer conical surface of each bottomed conical disk. When multiple stirring fins are fixed on the outer conical surface of each bottomed conical disk, the multiple stirring fins should be arranged at equal intervals. This not only improves the stirring effect, but also improves the balance of the rotating cone disk group and makes the rotation smoother.

[0018] Preferably, the stirring fin is a trapezoidal plate protruding from the outer conical surface of the bottomed conical disk along the radius direction of the bottomed conical disk, and two mutually parallel sides of the trapezoidal plate are respectively parallel to the generatrix of the bottomed conical disk.

[0019] like Figure 2 As shown, the fixed cone disc group is a combined fixed cone disc group, and a plurality of positioning pins 30 arranged at equal angles are provided between the upper support plate and the lower support plate. An annular positioning plate 35 is welded on the outer edge of the fixed cone disc, and positioning pin holes corresponding to the positions and numbers of the positioning pins are opened on the annular positioning plate. A spacing tube 28 is mounted on the positioning pins between adjacent annular positioning plates. Figure 2 In the embodiment, four positioning pins are used, and four positioning pin holes are opened on the annular positioning plate. The inner diameter of the distance tube is larger than the diameter of the positioning pin, and the outer diameter of the distance tube is larger than the diameter of the positioning pin hole.

[0020] like Figure 3 As shown, the rotating cone disk group is a combined rotating cone disk group, a cone disk shaft 9 is provided between the upper support plate mounting bearing 5 and the lower support plate mounting bearing 10, the upper end of the cone disk shaft is connected to the driving motor, an axial hole is opened at the center position of the bottom of the rotating cone disk, a distance sleeve 8 matching with the cone disk shaft is provided at the edge of the axial hole, the cone disk shaft is a prismatic shaft, and the distance sleeve is a prismatic center hole matching with the prismatic shaft.

[0021] When the fruit wine dealcoholization kettle of the present invention is working, the alcohol-containing liquid enters the middle kettle body through the alcohol-containing liquid upper injection pipe and / or the alcohol-containing liquid lower injection pipe, flows step by step from top to bottom in the multi-stage return flow channel, and finally exits the dealcoholization kettle through the alcohol-free liquid discharge pipe on the bottom plate cover of the lower kettle body. Figure 4 As shown, the alcohol-containing liquid is heated and stirred when passing through the multi-stage return flow channel, causing the alcohol to become gaseous. It enters the annular space between the straight cylinder retaining ring and the inner wall of the middle kettle body along the exhaust ring gap at the highest point of each stage of the return flow channel, and finally reaches the upper part of the middle kettle body, and is discharged from the dealcoholization kettle through the alcohol gas exhaust pipe.
