Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of liquid concentration and evaporation, and in particular to a high-efficiency evaporation and concentration device. [Background Technology]
[0002] In the field of concentration and evaporation of sugar syrups and similar liquids, the traditional heating and boiling method achieves evaporation and concentration by heating the entire liquid. This method has several problems in practice, such as uneven stirring at the bottom of the liquid leading to localized high temperatures, which can cause carbonization, charring, and discoloration. These problems not only affect the quality of the concentrated liquid but also negatively impact the appearance and taste of downstream products, especially in the food processing industry.
[0003] Taking the production of candied kumquats as an example, the sugar-soaking process requires prolonged soaking of the kumquats and continuous concentration of the syrup to increase its sugar content. Traditional methods involve heating the kumquats and syrup together. However, this simultaneous heating makes stirring difficult, easily causing the syrup to carbonize, burn, and turn black. This results in significant differences between batches of candied fruit, including variations in taste and color. These differences reduce the product's market competitiveness and increase production costs, necessitating a device that can solve these problems.
[0004] Based on the above background, it is necessary to design a concentration and evaporation device that can adapt to liquids such as sugar water and similar liquids, effectively reduce the coking problem caused by uneven heat dissipation, and improve production operation, efficiency and liquid quality. [Utility Model Content]
[0005] The purpose of this invention is to provide a high-efficiency evaporation and concentration device that can achieve efficient evaporation and concentration of liquids, solve the problems of carbonization, coking and discoloration caused by uneven heat dissipation in traditional methods, and thus improve the quality of concentrated liquids.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A high-efficiency evaporation and concentration device, comprising:
[0008] A container used to hold liquid that is to be evaporated and concentrated;
[0009] A heating assembly is disposed inside a container. The heating assembly includes at least two concave bends and at least two convex bends, which are arranged alternately to form an alternating concave-convex bend structure. One end of the bend structure is located at the beginning of the concave or convex bend, and the other end enters the concave portion of the second and subsequent concave bends after the last concave or convex bend, after wrapping around the bend structure at least half a turn from the top or bottom. The heating assembly is heated by steam and / or electric heating wire.
[0010] The lifting component is used to drive the heating element to move up and down inside the container so that the heating element is always in the upper part of the liquid when it is working.
[0011] The optimized technical solution also includes a support bracket, which is located at the bottom of the heating component to support the heating component and move it up and down under the action of the lifting component.
[0012] A further optimized technical solution involves a concave bend and a convex bend forming a continuous channel, within which steam or an electrothermal medium is transferred to heat the liquid.
[0013] A further optimized technical solution includes a heating component heated by steam, and also includes a steam pipe and an exhaust pipe. One end of the steam pipe is connected to the bend structure via a flexible hose, and the other end of the exhaust pipe is connected to the bend structure via a flexible hose.
[0014] A further optimized technical solution involves having N sets of heating components arranged sequentially inside the container, where N ≥ 2.
[0015] A further optimized technical solution includes a bracket comprising multiple support rods, which are fixed to the heating component via connectors to maintain the stability of the heating component.
[0016] The further optimized technical solution involves 3-6 concave bends and 3-6 convex bends.
[0017] The further optimized technical solution is that the upper part of the liquid is within 5-15cm below the liquid surface.
[0018] The further optimized technical solution includes a discharge port on the container, and each discharge port is equipped with a valve to control the entry and exit of liquids or objects.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0020] 1. This utility model provides a high-efficiency evaporation and concentration device. By incorporating a heating assembly consisting of alternating concave and convex curved tubes within the container, the curved tube structure provides uniform heating, allowing for precise temperature control of the surface area and avoiding problems such as localized overheating, carbonization, or discoloration at the bottom that can occur with traditional centralized heating methods. Furthermore, a lifting component ensures that the heating assembly remains positioned in the upper half of the liquid, facilitating heat transfer. This not only prevents the liquid from scorching due to high temperatures at the bottom but also achieves accelerated evaporation at the liquid surface, reaching evaporation and concentration at 70-80 degrees Celsius.
[0021] 2. By adding a support frame and lifting components, higher structural stability is provided, preventing uneven heating and damage to the heating components caused by shaking. At the same time, the heating components are not obstructed during the loading and unloading of materials, resulting in more efficient production. In addition, the support frame can also intercept the kumquats at the bottom during the evaporation and concentration process, preventing a large number of kumquats from reaching the surface evaporation zone and causing uneven temperature distribution in some areas of the evaporation zone.
[0022] 3. Multiple heating elements (N groups) are arranged sequentially, either horizontally or vertically, significantly improving the heating uniformity of large-volume liquids, making it suitable for mass production needs. The coordinated operation of multiple heating elements also effectively improves the overall evaporation and concentration efficiency.
[0023] 4. By limiting the number of concave and convex bends to between 3 and 6, the heat transfer path is optimized, satisfying the requirements of evaporation and concentration while avoiding pressure loss or reduced heat transfer efficiency caused by too many bends. The other end, after the last concave or convex bend, enters the concave portion of the middle bend after circling the bend structure at least half a turn from the top or bottom, significantly improving heating uniformity.
[0024] 5. The heating element's heating range in the upper part of the liquid is 5-15cm below the liquid surface, effectively balancing concentration efficiency and liquid quality. [Attached Image Description]

[0032] Example 1
[0033] See attached document Figure 1 and attached Figure 2 A high-efficiency evaporation and concentration device, characterized in that it comprises:
[0034] Container 1 is used to hold the liquid to be evaporated and concentrated;
[0035] Heating component 6 is disposed inside container 1. Heating component 6 includes at least two concave bends 61 and at least two convex bends 62. The concave bends 61 and convex bends 62 are arranged alternately to form a bend structure with alternating concave and convex shapes. One end of the bend structure is located at the beginning of the concave bend 61 or convex bend 62, and the other end enters the concave part of the second and subsequent concave bends 61 after the last concave bend 61 or convex bend 62 from the upper or lower part, after at least half a turn around the bend structure. Heating component 6 is heated by steam and / or electric heating wire.
[0036] The lifting component 8 is used to drive the heating component 6 to move up and down inside the container 1 so that the heating component 6 is always in the upper part of the liquid when it is working.
[0037] The optimization also includes a bracket 9, which is located at the lower part of the heating component 6 to support the heating component 6 and to move it up and down under the action of the lifting component 8.
[0038] In the optimized configuration, the concave bend 61 and the convex bend 62 form a continuous channel, through which steam or an electric heating medium is transferred to heat the liquid.
[0039] The optimized heating component 6 is heated by steam and also includes a steam pipe 2 and an exhaust pipe 3. The steam pipe 2 is connected to one end of the bend structure via a hose 5, and the exhaust pipe 3 is connected to the other end of the bend structure via a hose 5.
[0040] See attached document Figure 3 Container 1 contains N sets of heating components 6 arranged in sequence, where N≥2.
[0041] The bracket 9 includes multiple support rods, which are fixed to the heating component 6 by connectors to maintain the stability of the heating component 6.
[0042] The number of concave bends 61 is 3-6, and the number of convex bends 62 is 3-6. The optimal number of concave bends 61 is 3, and the number of convex bends 62 is 3. The heating element heats the upper part of the liquid, that is, within 5-15cm below the liquid surface.
[0043] The optimized container 1 is equipped with a discharge port, and each discharge port is equipped with a valve to control the entry and exit of liquids or objects.
[0044] The usage method and working principle of this utility model:
[0045] The lifting mechanism 8 is activated, causing the heating element 6 to rise above the container 1. The material to be evaporated and concentrated, in this embodiment, is a mixture of kumquats and sugar water, which is then injected into the container 1. The liquid level is ensured to be within the working range of the heating element 6 (recommended to be 5-15cm above the liquid surface). In this embodiment, the liquid level is approximately 50cm. The lifting mechanism 8 is then activated to ensure that the heating element 6 is positioned in the upper half of the liquid and can move up and down with changes in the liquid level to maintain optimal heating efficiency. In this embodiment, it is positioned within 10cm ± 1cm below the liquid surface.
[0046] Depending on specific needs, the heating assembly 6 connects to the steam pipe 2 and the exhaust pipe 3, or activates the heating wire to ensure normal transmission of the heating medium. This embodiment uses steam heating; the valve of the steam pipe 2 is opened to adjust the steam pressure; simultaneously, the exhaust pipe 3 is ensured to be unobstructed to discharge cold gas. The alternating arrangement of concave bends 61 and convex bends 62 in the heating assembly 6 allows for uniform heat conduction through continuous channels, thereby efficiently heating the liquid. In this embodiment, there are three concave bends 61 and three convex bends 62. One end of the bend structure is located at the beginning of the concave bend 61, and the other end, after the last convex bend 62, winds around the bend structure from below at least half a turn before entering the concave portion of the second concave bend 61.
[0047] During the heating process, the lifting component 8 dynamically adjusts the position of the heating component 6 according to the liquid level, ensuring that it is always in the upper part of the liquid, thereby improving heating efficiency and reducing energy waste.
[0048] As the liquid is heated, it gradually becomes concentrated inside the container.
[0049] If multiple heating components 6 (N≥2) are used, the heating intensity of each component can be adjusted according to actual needs to achieve efficient evaporation and concentration in stages. When the liquid is concentrated to the predetermined target, the heating source is turned off, and the lifting component 8 operates to drive the heating components 6 to rise above the container 1 for discharge.

However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
