Description

Technical Field

[0001] The invention relates to the technical field of beverage production, in particular to a production device for plant beverage. Background Art

[0002] In the field of plant beverage production and preparation, especially fruit juice beverages, there are mainly two methods: fresh squeezed canning and juice slurry concentration. Fresh squeezed canning can retain the fresh taste of the juice to the greatest extent, while juice slurry concentration removes a certain proportion of water in the juice by heating and other means to obtain a juice beverage of the required concentration. It has the advantages of flexible adjustment of juice concentration and extended product shelf life. In the process of juice concentration, a heating tank is usually used for concentration operation;

[0003] The Chinese patent publication number CN117258321B discloses a slurry concentrating device for processing fruit juice beverages, in which a heat equalizing device is provided, which enables the stirring rod and other components to cooperate to drive the flip ring to move up and down, so that when the heating device heats the juice, the flip ring continuously disturbs the juice, greatly improving the uniformity of heating and effectively reducing the problem of low evaporation concentration efficiency caused by uneven heating of the juice;

[0004] During the heating process of juice, as the heating time increases, the heating temperature will gradually increase, and too high a temperature will cause a large amount of nutrients in the juice to be lost. To address this problem, current heating devices generally use a vacuum structure to extract the air in the tank before feeding. This can not only reduce the loss caused by heat convection and increase the heating speed, but also reduce the temperature of water evaporation to a certain extent, thereby protecting the nutrients in the juice.

[0005] However, in the prior art, juice is usually fed in through a feeding pipe, during which air is easily mixed in. At the same time, when the juice is stirred by a stirring rod, the movement of the stirring rod disturbs the surrounding air, which increases the contact between air and juice, thereby accelerating the loss of heat, resulting in a decrease in heating speed, a prolonged heating time, and an increased risk of loss of nutrients in the juice.

[0006] In view of this, we propose a production device for plant beverages. Summary of the invention

The inner cavity entry tube can absorb the heat in the heated concentration chamber to preheat the transported plant beverage. The output end of the inner cavity entry tube is close to the heating mechanism, which is used to quickly heat the plant beverage and reduce the entry of air when transporting the plant beverage.

[0012] As a further improvement of the present technical solution, a partition is fixedly connected to the inside of the inner cavity tube, and the installation position of the partition is higher than the feed hole. The partition divides the inside of the inner cavity tube into a driving bin and a feeding bin. The driving bin is located at the top of the feeding bin, and a right-angle gear box is fixedly installed inside the driving bin.

[0014] As a further improvement of the technical solution, a floating plate is sealed and installed on the upper end of the inner cavity of the high-temperature cavity. The floating plate is made of heat-absorbing material, and a plurality of heat-adding blocks are fixedly connected to the surface of one side of the floating plate close to the heating and concentrating cavity.

At the same time, slow flow transportation can reduce the turbulence generated during feeding, so that the plant beverage entering the heating and concentration chamber is more stable. In addition, the inner cavity tube fits the inner wall of the heating and concentration chamber, which can absorb the heat in the cavity, so that the plant beverage can be preheated during the transportation process, reducing the subsequent heating time;

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For examples, see Figure 1 and Figure 2As shown, the purpose of this embodiment is to provide a plant beverage production device, including a concentration tank body 1, wherein a heating concentration chamber 13 is formed inside the concentration tank body 1, a movable cover body 12 is sealedly installed on the top of the concentration tank body 1, and a plurality of vacuum exhaust pipes 11 are arranged at one end of the concentration tank body 1 close to the movable cover body 12, and the plurality of vacuum exhaust pipes 11 are used to vacuum exhaust the heating concentration chamber 13, and a heating mechanism 3 is arranged inside the inner wall of the heating concentration chamber 13, and the heating mechanism 3 is divided into two parts, which are respectively located at the bottom end and the side wall of the heating concentration chamber 13, and are used to perform multi-faceted heating on the inside of the heating concentration chamber 13;

[0039] A cavity inlet mechanism 2 is provided inside the concentration tank body 1, and the cavity inlet mechanism 2 includes an outer material inlet tube 21 and an inner material inlet tube 22. The outer material inlet tube 21 and the inner material inlet tube 22 are sealed and connected. The outer material inlet tube 21 is located outside the concentration tank body 1, and the inner material inlet tube 22 is attached to the inner wall of the heating concentration chamber 13. The inner material inlet tube 22 can absorb the heat in the heating concentration chamber 13 to preheat the transported plant beverage. The output end of the inner material inlet tube 22 is close to the heating mechanism 3, which is used to quickly heat the plant beverage and reduce the entry of air when transporting the plant beverage.

[0040] In order to shorten the heating time of the plant beverage, it is necessary to maintain a vacuum or low vacuum state in the heating and concentrating chamber 13 to reduce the temperature of evaporation of water in the plant beverage. However, when the plant beverage is fed into the chamber, it is easy to carry air in. Therefore, it is necessary to assist the plant beverage in entering the chamber with the aid of an entry mechanism 2. The specific structure of the entry mechanism 2 is disclosed below. The entry mechanism 2 includes an entry hole 23 opened on the surface of an inner entry tube 22. The end of the outer entry tube 21 is sealed and connected to the inside of the entry hole 23. The outer entry tube 21 is installed horizontally and the inner entry tube 22 is installed vertically. The top end of the inner entry tube 22 is attached to the top of the inner cavity of the heating and concentrating chamber 13, and the bottom end of the inner entry tube 22 is attached to the bottom of the inner cavity of the heating and concentrating chamber 13.

[0041] A partition is fixedly connected to the inside of the inner cavity tube 22, and the installation position of the partition is higher than the feed hole 23. The partition divides the inside of the inner cavity tube 22 into a driving bin 25 and a feed bin 24. The driving bin 25 is located at the top of the feed bin 24, and a right-angle gear box 27 is fixedly installed inside the driving bin 25. A driving motor is installed on the side wall of the concentration tank body 1, and the horizontal axis of the right-angle gear box 27 is fixedly connected to the output shaft of the driving motor. A spiral drive shaft 26 is rotatably arranged inside the feed bin 24, and the vertical axis of the right-angle gear box 27 is fixedly connected to the top of the spiral drive shaft 26.

[0042] Combination Figure 3 and Figure 4As shown, when the plant beverage needs to be transported, the drive motor is started, and the drive motor drives the right-angle gear box 27 to which its output shaft is fixedly connected to start, and another output shaft of the right-angle gear box 27 drives the spiral drive shaft 26 to rotate in the feed bin 24. With the transportation of the plant beverage and the rotation of the spiral drive shaft 26, the plant beverage can be spirally transported to the bottom end of the feed bin 24 (i.e., the bottom of the inner cavity of the heating concentration chamber 13) in a slow-flow manner. The plant beverage is pushed forward in a spiral manner by the rotation of the spiral drive shaft 26, forming a relatively stable transport flow state. This spiral motion makes the plant beverage fit closely during the transportation process, reduces the gap and space for air to enter, and thus effectively reduces the mixing of air.

[0043] At the same time, the rotation of the spiral drive shaft 26 pushes the plant beverage forward in a spiral manner. When discharged into the heating and concentration chamber 13, the plant beverage is in a stable flow state. This spiral conveying method can reduce turbulence and reduce the mixing of air, and can ensure that the heating and concentration chamber 13 is in a vacuum or low vacuum state. In a vacuum or low vacuum state, the boiling point of the liquid will be lowered, making it easier for water to evaporate, making the concentration speed faster, reducing the time of the plant beverage in the heating process, and thus reducing the loss of nutrients.

[0044] The working principle of the above-mentioned right-angle gearbox 27 is well known to those skilled in the art. It mainly utilizes mutually meshing bevel gears to change the direction of power transmission. When power enters from the input shaft, the meshing action of the gears converts the rotational motion of the input shaft into the rotational motion of the output shaft that is at a right angle to the input shaft, thereby realizing the transmission of power in the right-angle direction.

[0045] A one-way valve (not shown in the figure) is provided near the bottom opening of the feed hopper 24. With the help of the spiral drive shaft 26, the batch of plant beverages can be completely transported. When the same batch of plant beverages to be concentrated is transported, the drive motor stops running. At this time, due to a certain pressure difference between the inner cavity tube 22 and the low vacuum cavity, coupled with the structure of the one-way valve, the plant beverage that has entered the heating and concentration chamber 13 can be effectively prevented from flowing back to the inner cavity tube 22. In this way, the plant beverage can be stably heated and concentrated in the heating and concentration chamber 13.

[0046] When a plant beverage (such as juice) is concentrated, it needs to be heated to evaporate the water in the plant beverage. Therefore, it is necessary to use a heating mechanism 3 to increase the temperature in the heating and concentrating chamber 13. The specific structure of the heating mechanism 3 is disclosed below. The heating mechanism 3 includes a side temperature chamber 31 opened inside the inner wall of the heating and concentrating chamber 13. The side temperature chamber 31 is close to the lower end of the heating and concentrating chamber 13. A low-temperature heating sleeve 32 is arranged inside the side temperature chamber 31. A high-temperature chamber 33 is opened at the bottom of the inner cavity of the heating and concentrating chamber 13, and a disc-type high-temperature heating tube 34 is installed inside the high-temperature chamber 33.

[0047] See also Figure 6 and Figure 7 As shown, the low-temperature heating sleeve 32 is located inside the lower end of the heating and concentrating chamber 13, and can assist in heating the concentrating chamber 13 to maintain a constant temperature. The disc-type high-temperature heating tube 34 is located at the bottom of the inner cavity of the heating and concentrating chamber 13, and the lower end opening of the inner cavity tube 22 is facing the disc-type high-temperature heating tube 34. In this way, the plant beverage that has just entered the heating and concentrating chamber 13 can contact the heating source, which effectively improves the heating speed and heating effect of the plant beverage.

[0048] Combination Figure 8 It can be seen that the inner cavity tube 22 is located inside the heating and concentrating chamber 13, and the side wall of the inner cavity tube 22 is in contact with the inner wall of the heating and concentrating chamber 13. Under the joint action of the low-temperature heating sleeve 32 and the disc-type high-temperature heating tube 34, the interior of the heating and concentrating chamber 13 is in a relatively high temperature state. Through the heat conduction of the inner cavity tube 22 itself (the inner cavity tube 22 can be made of metal materials with good heat absorption effect, such as stainless steel, copper, nickel-based alloy, etc.), the internal temperature of the inner cavity tube 22 is higher than the external temperature. By utilizing the spiral drive shaft 26, the plant beverage stays in the inner cavity tube 22 for a relatively long time. Therefore, the plant beverage can be preheated while feeding, thereby shortening the heating time of the plant beverage in the heating and concentrating chamber 13, thereby achieving the effect of reducing the loss of nutrients in the plant beverage.

[0049] With the continuous delivery of the plant beverage, although the plant beverage newly entering the heating and concentration chamber 13 is preheated, its heat is still lower than that of the plant beverage heated by the disc-type high-temperature heating tube 34. When a new plant beverage with a relatively low temperature enters, due to the principle of thermal expansion and contraction and the density difference caused by the temperature difference, the plant beverage with a relatively high temperature in the heating and concentration chamber 13 flows upward due to its low density, while the newly entering plant beverage with a relatively low temperature sinks due to its high density, thereby forming natural convection. This convection mixing method allows plant beverages of different temperatures to interact with each other, promotes the transfer and uniform distribution of heat, and achieves the effect of natural mixing without the aid of mechanical stirring and mixing, which not only reduces the mixing of air, but also reduces heat loss, and can achieve water evaporation more quickly.

[0050] in, Figure 4 , Figure 5 , Figure 6 and Figure 8 The dotted arrows in the figure all indicate the flow direction of the plant beverage into the cavity; Figure 4 and Figure 8 The hollow line in the figure indicates the heat dissipation direction of the low-temperature heating sleeve 32 and the disc-type high-temperature heating tube 34.

[0051] Since the temperature of the disc-type high-temperature heating tube 34 needs to be set relatively high to ensure that the temperature inside the heating and concentrating chamber 13 is capable of concentrating the plant beverage, if the plant beverage directly contacts the disc-type high-temperature heating tube 34 when being fed, it is easy to affect the preservation of nutrients in the plant beverage due to excessive temperature. In view of this, a floating plate 4 is sealed and installed on the upper end of the inner cavity of the high-temperature chamber 33. The floating plate 4 is made of heat-absorbing material, and a plurality of heating blocks 41 are fixedly connected to the surface of one side of the floating plate 4 close to the heating and concentrating chamber 13.

[0052] The improvement lies in: combining Figure 5 and Figure 7 As shown, the floating plate 4 (made of metal with good thermal conductivity) is installed at the upper end of the inner cavity of the high-temperature chamber 33, playing a certain barrier role to prevent the plant beverage from directly contacting the high-temperature heating tube when feeding. The surface of the floating plate 4 close to the heating and concentration chamber 13 is fixedly connected to a plurality of heat adding blocks 41. These heat adding blocks 41 can increase the area of ​​the floating plate 4, thereby achieving better heat conduction. In this way, the heating and concentration effect is guaranteed, and the damage to the nutrients in the plant beverage caused by high temperature can be effectively reduced.

[0053] In order to reduce the large fluctuations caused by the plant beverage entering the heating and concentration chamber 13, the lower end opening of the inner cavity tube 22 is close to the middle of the heating and concentration chamber 13, and the outer wall of the lower end opening of the inner cavity tube 22 is fixedly connected with a lead plate 5, which is in an inclined state.

[0054] like Figure 5 As shown, when the plant beverage enters the heating and concentrating chamber 13, it is easy to fluctuate due to factors such as the feeding speed and pressure. Such fluctuations will interfere with the convection in the heating and concentrating chamber 13 and destroy the originally naturally formed thermal convection cycle. Therefore, a lead plate 5 is fixedly connected to the outer wall of the lower end opening of the inner cavity tube 22, so that the plant beverage can enter the heating and concentrating chamber 13 more smoothly, reducing the adverse effects of such fluctuations, ensuring that the plant beverage can stably perform heating and concentration operations in the heating and concentrating chamber 13, thereby improving the concentration quality and efficiency of the plant beverage.

[0055] Considering the sealing condition inside the feeding bin 24 , a sealing layer 6 is fixedly connected to the outer wall of the spiral drive shaft 26 . The sealing layer 6 is made of elastic material and is used to improve the overall sealing property inside the feeding bin 24 .

[0056] The improvement lies in: combining Figure 3 and Figure 4It can be seen that the outer wall of the spiral drive shaft 26 is fixedly connected to the sealing layer 6. The sealing layer 6 can fill the gap between the outer wall of the spiral drive shaft 26 and the inner wall of the feed bin 24 through its elastic material, effectively preventing air from entering, and ensuring that the plant beverage is transported in a relatively closed environment, thereby ensuring the quality of the plant beverage and the heating and concentration effect. Among them, the sealing layer 6 is preferably made of rubber material, which will not cause significant friction damage to the inner wall of the feed bin 24 while achieving a good sealing effect.

[0057] In order to improve the heat conduction effect of the inner cavity tube 22 and its own installation stability, two heat conduction semi-arc plates 7 are fixedly connected to the surface of one side of the inner cavity tube 22 close to the inner wall of the heating and concentrating chamber 13, and the other sides of the two heat conduction semi-arc plates 7 are both in contact with the inner wall of the heating and concentrating chamber 13.

[0058] The improvements are: See Figure 8 As shown, the contact area between the inner cavity tube 22 and the heating and concentration chamber 13 can be increased by the heat-conducting semi-arc plate 7, thereby improving the heat conduction efficiency, so that the plant beverage in the inner cavity tube 22 can absorb heat more quickly, and accelerate the heating and concentration process. At the same time, the fit between the heat-conducting semi-arc plate 7 and the inner wall of the heating and concentration chamber 13 also provides support and fixation for the inner cavity tube 22, enhances the installation stability of the inner cavity tube 22 in the heating and concentration chamber 13, reduces its shaking or displacement under the flow of plant beverage or other external forces, and ensures the normal operation of the entire heating and concentration system. Among them, the heat-conducting semi-arc plate 7 can be made of the same material as the inner cavity tube 22.

[0059] In summary, the working principle of the present scheme is as follows: when the plant beverage needs to be heated and concentrated, the interior of the heating and concentrating chamber 13 is first vacuumed through the vacuum exhaust pipe 11, and then the low-temperature heating sleeve 32 and the disc-type high-temperature heating tube 34 are turned on, and then the driving motor is turned on, and the plant beverage that needs to be heated and concentrated is fed through the external feeding pipe 21, and the driving motor drives the right-angle gear box 27 to which its output shaft is fixedly connected to start, and another output shaft of the right-angle gear box 27 drives the spiral drive shaft 26 to rotate in the feeding bin 24. With the transportation of the plant beverage and the rotation of the spiral drive shaft 26, the plant beverage can be spirally conveyed to the bottom end of the feeding bin 24 in a slow-flow manner, and the rotation of the spiral drive shaft 26 pushes the plant beverage forward in a spiral manner, forming a relatively stable conveying flow state. This spiral motion makes the plant beverage fit closely during the transportation process, reduces the gaps and spaces for air to enter, and thus effectively reduces the mixing of air;

[0060] The low-temperature heating sleeve 32 is located inside the lower end of the heating and concentrating chamber 13, and can assist in heating the concentrating chamber 13 to maintain a constant temperature. The disc-type high-temperature heating tube 34 is located at the bottom of the inner cavity of the heating and concentrating chamber 13, and the lower end opening of the inner cavity tube 22 faces the disc-type high-temperature heating tube 34. In this way, the plant beverage that has just entered the heating and concentrating chamber 13 can contact the heating source, which effectively improves the heating speed and heating effect of the plant beverage.

[0061] Under the joint action of the low-temperature heating sleeve 32 and the disc-type high-temperature heating tube 34, the interior of the heating and concentrating chamber 13 is in a relatively high temperature state. Through the heat conduction of the inner cavity tube 22 itself, the internal temperature of the inner cavity tube 22 is made higher than the external temperature. By utilizing the spiral drive shaft 26, the plant beverage can stay in the inner cavity tube 22 for a relatively long time. Therefore, the plant beverage can be preheated while feeding. When a new plant beverage with a relatively low temperature enters, due to the principle of thermal expansion and contraction and the density difference caused by the temperature difference, the plant beverage with a relatively high temperature originally in the heating and concentrating chamber 13 flows upward due to its low density, and the newly entered plant beverage with a relatively low temperature sinks due to its high density, thereby forming natural convection. This convection mixing method allows plant beverages of different temperatures to interact with each other, promotes the transfer and uniform distribution of heat, and achieves the effect of natural mixing without the aid of mechanical stirring and mixing. It not only reduces the mixing of air, but also reduces the loss of heat, and can achieve water evaporation more quickly.
