Description

Technical Field

[0001] This utility model relates to the field of polycrystalline rock sugar production technology, and in particular to an intelligent polycrystalline rock sugar crystallization device. Background Technology

[0002] In traditional polycrystalline rock sugar production processes, the heating, stirring, and temperature control of the syrup during melting rely heavily on manual operation, resulting in low efficiency and difficulty in ensuring syrup uniformity and stability, leading to energy waste and inconsistent product quality. Secondly, insufficient temperature control precision during crystallization makes it difficult to achieve precise cooling according to a preset curve, affecting crystal nucleation and growth, resulting in low crystallization efficiency and uneven crystal size. Furthermore, the separation of mother liquor and crystals often relies on manual or simple mechanical methods, leading to incomplete separation and inefficient cleaning and drying processes, which can cause cross-contamination and equipment corrosion. In addition, the lack of intelligent control during sugar block crushing makes it difficult to adjust crushing pressure and frequency, easily resulting in over-crushed or incompletely crushed sugar blocks, affecting finished product quality. Therefore, there is an urgent need to develop an intelligent device integrating melting, crystallization, separation, and crushing to achieve full-process automation, precise temperature control, efficient separation, and controllable crushing, thereby improving the production efficiency and product quality of polycrystalline rock sugar.

[0023] Reference Figure 1 An intelligent polycrystalline rock sugar crystallization device according to an embodiment of this utility model includes a melting chamber 100, a crystallization chamber 120, and a collection chamber 140. The melting chamber 100 and the collection chamber 140 are arranged side by side and separated by a partition wall 112 to prevent steam and sulfides from the melting chamber 100 from flowing into the collection chamber 140, thereby keeping the collection chamber 140 clean and preventing corrosion of the equipment in the collection chamber 140. The crystallization chamber 120 is located above the melting chamber 100 and the collection chamber 140, and is separated from the melting chamber 100 and the collection chamber 140 by a rotatable base plate 121 to prevent steam and sulfides from flowing into the crystallization chamber 120 during the sugar melting process, thus preventing pollution and corrosion.

[0024] Reference Figure 2The sugar melting chamber 100 is equipped with a feeding device 101, a first container 102, and a metering pump 103. The feeding device 101 includes a rotatable mounting plate 109 and a feeding hopper 105 and a water inlet pipe 106 mounted on the mounting plate 109. Both the feeding hopper 105 and the water inlet pipe 106 are equipped with valves for opening and closing water and feeding. A first pivot shaft 108 is provided on one side of the first container 102. The mounting plate 109 is connected to the first pivot shaft 108. Furthermore, a first cylinder 115 is provided on the outside of the first container 102. The first cylinder 115 is connected to the end of the mounting plate 109 away from the first container 102 and can drive the mounting plate 109 to rotate, thereby adjusting the height of the water inlet pipe 106 and the feeding hopper 105 and the angle of water and feeding. Understandably, during the feeding process, the sugar entering the first container 102 from the feed hopper 105 tends to accumulate on one side of the first container 102, which is not conducive to mixing with water. Therefore, during feeding, the first cylinder 115 drives the mounting plate 109 to swing back and forth, thereby ensuring that the sugar can be evenly distributed in the first container 102, facilitating subsequent mixing and stirring processes. During the water feeding process, the first cylinder 115 drives the mounting plate 109 to swing back and forth, which allows the water inlet pipe 106 to inject water into the second container 122 at different angles, facilitating full contact between water and sugar and improving sugar melting efficiency.

[0025] It is understood that a stirring mechanism 111 is provided inside the sugar melting chamber 100. The stirring mechanism 111 includes a stirring paddle 1111 and a first motor 116 located outside the sugar melting chamber 100. The first motor 116 can drive the stirring paddle 1111 to rotate and stir the sugar, so that it is fully mixed with water to realize the sugar melting process. The first motor 116 is located outside the sugar melting chamber 100 to avoid contact with the steam and sulfides generated during sugar melting, thus avoiding corrosion and affecting its lifespan. In this embodiment, the feed hopper 105 is located between the water inlet pipe 106 and the first pivot shaft 108. Because the mounting plate 109 is tilted during operation (e.g., Figure 2 As shown, the lower feed hopper 105 reduces the probability of sugar spilling onto the top of the mixing paddle 1111, thus preventing sugar from accumulating at the bottom of the mixing paddle 1111 and failing to melt. Furthermore, the upper water inlet pipe 106 flushes the mixing paddle 1111 during water injection, facilitating cleaning of its surface and preventing sugar from adhering, thereby improving sugar utilization and facilitating cleaning of the mixing paddle 1111 during the cleaning process. Simultaneously, a first heater 104 is provided at the bottom of the first container 102, which increases the temperature of the syrup inside the first container 102 to improve melting efficiency.

[0026] It is understood that a metering pump 103 is provided on the side of the first container 102 away from the first cylinder 115. The metering pump 103 is used to extract the melted syrup in the first container 102 and transfer the syrup to the second container 122 in the crystallization chamber 120. At the same time, the metering pump 103 can calculate the flow rate to monitor and control the syrup flow rate.

[0027] Furthermore, a drain valve 107 is provided at the bottom of the first container 102. The drain valve 107 is located on the side away from the metering pump 103. At the same time, the bottom wall of the first container 102 is inclined downward from the metering pump 103 towards the drain valve 107, which is conducive to drainage during the cleaning process. Meanwhile, the first container 102 is equipped with a level gauge 113, which can measure the liquid level in the first container 102 to control the water injection volume and detect the liquid level of the syrup.

[0028] It is understood that the crystallization chamber 120 is provided with a base plate 121 and a second container 122, with the second container 122 mounted on the base plate 121. A second pivot shaft 125 is provided at the top of the partition wall 112, and the base plate 121 is rotatably connected to the partition wall 112 via the second pivot shaft 125. Furthermore, the sugar melting chamber 100 is provided with a second cylinder 128, which is connected to the end of the base plate 121 away from the collection chamber 140. The cylinder 128 can drive the base plate 121 to rotate, causing the second container 122 to tilt, thereby allowing the crystallized material to be poured into the collection chamber 140 after the crystallization process, thus collecting the polycrystalline rock sugar. In this embodiment, during the feeding process after crystallization, the second cylinder 128 can repeatedly operate, applying vibration to the second container 122, thereby causing the crystallized material to detach from the inner wall of the second container 122, which helps improve feeding efficiency and avoids crystallized material residue.

[0029] The second container 122 contains multiple crystallization tanks 123 arranged side by side, with partitions 129 separating adjacent crystallization tanks 123. Each crystallization tank 123 has a rounded inner bottom wall. It is understood that after the polycrystalline rock sugar crystallizes, the crystals adhere to the inner wall of the crystallization tank 123. Compared to a flat or right-angled bottom, the rounded bottom wall avoids sharp corners where stress concentration occurs. During the honey-water separation process, when the second cylinder 128 drives the bottom plate 121 to reciprocate at high frequency, the rounded inner wall of the crystallization tank 123 can more effectively transmit vibration to the entire crystal, making it easier for the crystals to detach completely from the tank wall. This significantly reduces the risk of crystal breakage due to stress concentration, ensuring the integrity and yield of the final product. Furthermore, after crystallization, all materials in the crystallization tank 123 (including rock sugar blocks and residual mother liquor) need to be poured into the collection chamber 140. The arc-shaped bottom wall forms a smooth flow channel, allowing for smoother material flow and eliminating dead corners during tilting and pouring. This ensures complete discharge of the crystals, avoids cross-contamination, and facilitates subsequent cleaning. Simultaneously, the arc-shaped geometry at the bottom of the crystallization tank 123 ensures more uniform convection of the solution during cooling and crystallization, reducing localized eddies and temperature unevenness. This provides a better fluid environment for uniform crystal nucleus formation and consistent crystal growth, contributing to improved crystal size uniformity.

[0030] Reference Figure 4 A crystallization plate 124 is provided inside the crystallization tank 123. The crystallization plate 124 extends along the depth direction of the crystallization tank 123 and divides the internal space of the crystallization tank 123 into two independent chambers. It can be understood that the crystallization plate 124 divides the originally large crystallization tank 123 space into two or more independent chambers, thus multiplying the surface area available for crystal attachment within the same equipment footprint and space, thereby significantly improving the single-batch crystallization output and production efficiency. At the same time, the crystallization plate 124 itself also provides additional crystal attachment surfaces. When the second cylinder 128 rapidly separates the crystallization surfaces, the presence of the crystallization plate 124 increases the stress points, and its own slight deformation or vibration also helps to break the bonding force between the crystal and all contact surfaces (including the sides of the crystallization plate 124 and the tank walls of the crystallization tank 123), making the crystal easier to detach as a whole, preparing it for the subsequent pouring process.

[0031] It is understandable that the height of the outer edge of the second container 122 is greater than the depth of the crystallization tank 123, so that only one syrup injection tube is needed to complete the syrup injection operation of all crystallization tanks 123 in the crystallization container, and it can ensure that the syrup can be distributed simultaneously and evenly to each separated chamber, thus ensuring the consistency of crystallization conditions in each part.

[0032] Furthermore, to facilitate real-time observation of the crystallization process, a camera 131 is installed between the inner wall of the crystallization chamber 120 and the crystallization tank 123, for reference. Figure 5 Meanwhile, an observation window 132 is provided on the side of the crystallization tank 123 near the camera 131. The observation window 132 is made of transparent material, preferably glass in this embodiment, and is embedded in the side wall of the crystallization tank 123. Furthermore, a sealing ring 133 is provided in the inner wall of the crystallization chamber 120, and the outer peripheral wall of the camera 131 is connected to the crystallization chamber 120 through the sealing ring 133. It can be understood that during the crystallization process, the outer peripheral wall of the crystallization tank 123 presses against the end wall of the sealing ring 133 to achieve a seal, preventing steam in the crystallization chamber 120 from entering the observation channel (i.e., the inner channel of the sealing ring 133), thereby ensuring the clarity of observation. When the crystallized material is poured out after crystallization, the second container 122 can move relative to the sealing ring 133. After pouring, the second container 122 returns to its original position, and the outer peripheral wall of the crystallization tank 123 can re-press against the sealing ring 133 to achieve a seal. Furthermore, a lighting lamp can be provided in the camera 131 to illuminate the observation channel, thereby improving the observation effect of the crystallized material.

[0033] Understandably, the crystallization chamber 120 is equipped with a second heater 127, a blower 126, and a thermometer 114. Simultaneously, a radiator 130 is installed on the side wall of the crystallization chamber 120. When the radiator 130 is opened, it allows the air inside the crystallization chamber 120 to communicate with the outside. The second heater 127 heats the second container 122 to reach the preset crystallization temperature. The thermometer 114 monitors the temperature inside the crystallization chamber 120 in real time. When the temperature inside the crystallization chamber 120 exceeds the preset temperature, the blower 126 and the radiator 130 are activated to allow outside air to enter the crystallization chamber 120, thereby lowering the temperature inside the crystallization chamber 120. This achieves real-time temperature control, ensuring that the crystallization process maintains a reasonable temperature, which is beneficial for improving product quality.

[0034] The collection chamber 140 is located on one side of the crystallization chamber 120. The collection chamber 140 includes a third container 144 and a crushing device 148. The top of the third container 144 is equipped with a filter assembly 141 and a discharge plate 145, which is pivotally connected to one side of the third container 144. (Refer to...) Figure 3The filter assembly 141 includes a first filter screen 142 and a second filter screen 143. The first filter screen 142 is located above the second filter screen 143. The filtration accuracy of the first filter screen 142 is less than that of the second filter screen 143, thus achieving two-stage filtration. This ensures the separation of mother liquor and crystals during the honey leaching process, facilitating subsequent crushing and grinding. During filtration, the discharge plate 145 is tilted upwards from the third container 144 towards the crushing device 148, while the first filter screen 142 tilts downwards towards the crushing device 148, allowing crystals to accumulate between the discharge plate 145 and the first filter screen 142. After filtration, the third cylinder 152 rotates the discharge plate 145 and tilts it downwards towards the crushing device 148, allowing the crystals to fall along the discharge plate 145 into the support platform 150 in the crushing device 148, thus completing the unloading operation. Furthermore, the filter assembly 141 is also equipped with a nozzle 147, located on the first side away from the unloading plate 145. The nozzle 147 can spray clean water to rinse the first filter screen 142 and the second filter screen 143, causing the crystals remaining on the first filter screen 142 and the second filter screen 143 to melt and fall into the third container 144, thereby cleaning the filter assembly 141 and preventing contamination of the next production process due to the residue of crystals. At the same time, a third heater 151 is provided at the bottom of the third container 144, which can heat the third container 144 and melt the crystals remaining at the bottom, facilitating cleaning. Furthermore, a drain valve 107 is provided on one side of the third container 144, which opens during the cleaning process to drain the solution at the bottom of the third container 144.

[0035] Understandably, the crushing device 148 is equipped with a second motor 153, which is connected to the crushing hammer 149 via a lead screw drive pair, thereby enabling the crushing hammer 149 to move up and down. Furthermore, the bottom of the crushing hammer 149 is provided with a spike 154, which can more effectively crush crystalline materials and improve crushing efficiency.

[0036] This invention achieves full automation and intelligence in the production of polycrystalline rock sugar through the deep integration of mechanical structure, electrical control and intelligent algorithms, which significantly improves production efficiency, product consistency and hygiene level, and is suitable for large-scale industrial production.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
