Description

Technical Field

[0001] This utility model relates to the field of rock sugar production technology, specifically to a vacuum concentration device for rock sugar production. Background Technology

[0002] Vacuum concentration of rock sugar refers to using a vacuum environment to lower the boiling point, allowing the rock sugar solution to evaporate water rapidly at a lower temperature, thus accelerating the sugar crystallization process. This method significantly reduces the content of impurities, making the rock sugar granules purer and more transparent, exhibiting a clear white color, and resulting in a purer taste.

[0003] Existing rock sugar vacuum concentration devices are mainly divided into horizontal and vertical types. Regardless of the type of vacuum concentration device, the concentrated rock sugar needs to be discharged in the end. However, the current rock sugar vacuum concentration devices cannot tilt or lift, and the tank is always kept horizontal, which is inconvenient during the process of discharging the rock sugar.

[0004] For example, document CN207845666U describes a single-crystal rock sugar crystallizer. In section

[0020] of the specification, seed crystals are added through the feeding port at the top of the crystallization chamber and evenly distributed on the sieve plate. The feeding cover is then closed, and the vacuum pipeline valve is opened via the control system to create a vacuum within the crystallization chamber. A suitable sugar solution is drawn in through the inlet under vacuum. The steam pipeline valve is opened via the control system, and steam is introduced into the disc-shaped steam pipe through the steam inlet. Simultaneously, the externally connected linkage structure is activated, causing the tank to swing. The sugar solution then heats up, boils, and evaporates within the crystallization chamber. After crystallization, the vacuum and steam pipelines are closed, the residual liquid is extracted, and the sealed door is opened to remove the single-crystal rock sugar. However, the crystallization chamber remains horizontal. After opening the sealed door, the rock sugar concentrates within the tank, requiring manual removal with tools. Therefore, we propose a vacuum concentration device for rock sugar production. Utility Model Content

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 6 This utility model provides a technical solution: a vacuum concentration device for producing rock sugar, including a tank 1, a feeding port 17 at the top of the tank 1, a detachable sealing cover at the top of the feeding port 17, the two being connected by a lock, an observation port 16 at the top of the tank 1, a detachable cover plate at the top of the observation port 16, a transparent window in the middle of the cover plate, and the cover plate being connected to the observation port 16 by a lock.

[0026] One end of the tank body 1 is provided with a discharge port 15, and a detachable sealing door 14 is provided on the discharge port 15. One side of the sealing door 14 is rotatably connected to the discharge port 15, so that the sealing door 14 can be opened or closed. The other side of the sealing door 14 is connected to the discharge port 15 by a latch or bolt, so that the sealing door 14 and the discharge port 15 are tightly connected. In order to facilitate observation of the internal condition of the tank body 1, a transparent observation port 13 is provided in the middle of the sealing door 14.

[0027] The bottom of tank 1 is mounted on the first support frame 3, such as Figure 1As shown, the edge of the tank 1 is connected to the first support frame 3 by multiple brackets 2. The first support frame 3 is horizontally placed on the second support frame 4, and the ends of the first support frame 3 and the second support frame 4 near the discharge port 15 are rotatably connected. The bottom of the first support frame 3 and the second support frame 4 are connected by a lifting mechanism.

[0028] To increase the structural strength of the second support frame 4, such as Figure 3 As shown, multiple reinforcing frames 19 are arranged in a cross pattern within the second support frame 4. The lifting mechanism includes a telescopic mechanism 5 rotatably mounted on the end of the reinforcing frame 19 away from the discharge port 15. The telescopic mechanism 5 is tilted upwards, and its top is rotatably mounted below the tank body 1. Here, the telescopic mechanism 5 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. It should be noted that, driven by the lifting mechanism, the tank body 1 is rotated from a horizontal state to an inclined state, that is, the telescopic mechanism 5 will press against the tank body 1 to lift and lower it. Therefore, the bottom of the tank body 1 is the stress point. In order to increase the structural strength of the tank body 1, a reinforcing seat (such as...) is set at the bottom of the tank body 1. Figure 6 (As indicated by the middle arrow A), the top of the telescopic mechanism 5 is rotated and installed below the reinforcing seat, which can strengthen the bottom of the tank 1.

[0029] The top of the tank 1 is connected to a negative pressure device, which includes an air extraction port 18 located on the top of the tank 1. The air extraction port 18 is connected to a vacuum pump via a pipe. The vacuum pump is a vacuum pump that can evacuate the inside of the tank 1. A valve is provided on the pipe connected to the vacuum pump. The valve moves synchronously with the vacuum pump, that is, the vacuum pump and the valve open and close at the same time.

[0030] The specific working process is as follows: external sugar water is added to tank 1 through feeding port 17. When the sugar water in the tank reaches the preset amount, the addition stops. At this time, the vacuum device evacuates the inside of tank 1. When the air pressure inside tank 1 decreases to the preset value, the vacuum device stops working. Due to the vacuum, the sugar water in tank 1 begins to boil and continuously generates steam, increasing the concentration of the sugar water. The top of tank 1 is equipped with at least two exhaust ports 21, which are connected to the condensing device through pipes. A circulating fan is installed on the pipes. In other words, the inlet and outlet of the condensing device are connected to the exhaust ports 21 through pipes. When the circulating fan operates, it drives the steam to circulate in the condensing device and tank 1, allowing the steam to be collected by the condensing device. In vacuum evaporation production, the combination of vacuum evaporation equipment and condensing device is a common method and one of the important ways to collect steam inside the vacuum evaporation equipment.

[0031] Furthermore, the bottom of the second support frame 4 is mounted on a swing mechanism. The function of the swing mechanism is to cause the second support frame 4 to sway left and right to a certain extent, such as... Figure 3As shown, the swing mechanism includes an arc-shaped support 12 installed below the second support frame 4. The arc-shaped support 12 is perfectly circular, and there are at least two arc-shaped supports 12 arranged symmetrically. Below each arc-shaped support 12, there are multiple arc-shaped distributed support groove wheels 10. There are three support groove wheels 10, distributed directly below and on both sides of the arc-shaped support 12. The two ends of the support groove wheels 10 are rotatably mounted inside the support 11, which is mounted on the base 9. This allows the arc-shaped support 12 to be placed within the support groove wheels 10, ensuring that the arc-shaped support 12 is not only supported but also rotates within the support groove wheels 10 without falling out.

[0032] A drive device is provided on one side of the second support frame 4. The drive device is used to drive the arc-shaped support 12 to move within the support groove wheel 10. The drive device includes a swing arm 6 rotatably mounted on one side of the second support frame 4. The bottom of the swing arm 6 is rotatably connected to one end of the drive arm 8. The drive arm 8 is vertically mounted on the drive motor 7. The drive motor 7 is mounted on the base 9. Therefore, when the drive motor 7 rotates, it can drive the second support frame 4 to sway left and right to a certain extent.

[0033] It should be noted that the oscillating mechanism is essential because as the tank 1 oscillates from side to side, it causes the sugar syrup inside to shake. As the water in the syrup gradually evaporates, the concentration of the sugar gradually increases. When the sugar syrup in the tank 1 begins to crystallize, the oscillation of the tank 1 not only prevents the rock sugar from adhering to the inner wall of the tank 1, but also causes the rock sugar particles to shake, thus making the rock sugar particles larger and larger, eventually forming large rock sugar particles. After the preset crystallization time, the sealing door 14 can be opened, and the telescopic mechanism 5 can be extended to allow the tank 1 and the... Figure 5 The canopy tilts downwards, and the rock sugar falls continuously along the outlet 15. In actual use, it is necessary to manually use tools such as shovels to reach into the can and scrape the rock sugar out, which can accelerate the discharge of the rock sugar.

[0034] Based on the above embodiments, it should be further emphasized that, as Figure 6 As shown, a heating device 20 is provided on the surface of the tank 1. The heating device 20 is a resistance wire or heating rod installed on the bottom surface of the tank 1. In actual use, a cover plate or insulation film or other shielding material needs to be placed on the heating device 20 to allow the heating device 20 to heat the tank 1. Because the temperature requirement of the vacuum evaporator is usually between 35 and 50°C, that is, vacuum evaporation can be accelerated in a certain temperature environment, the heating device 20 can be used to heat and keep warm when the temperature inside the tank 1 is lower than the set temperature.

[0035] Based on the above embodiments, further optimizations can be made, such as... Figure 2 As shown, a control cabinet (such as...) is also installed on the base 9. Figure 2(As indicated by the middle arrow B), the control cabinet is equipped with a controller, which is connected to the heating device 20, drive motor 7, telescopic mechanism 5, vacuum device, circulating fan and valve respectively;

[0036] A pressure sensor is installed on the top of the tank 1 to monitor the pressure value of the tank 1. The pressure sensor is connected to the controller.

[0037] A temperature sensor is installed on the surface of the monitoring tank 1 to detect the surface temperature of the tank. The sensor is connected to the controller. A pressure balancing valve is also installed on the top of the tank 1.

[0038] 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.
