Description

Technical Field

[0001] This utility model relates to the field of sugar boiling equipment technology, and in particular to a high vacuum sugar boiling machine. Background Technology

[0002] A sugar boiling machine is a mechanical device used for processing syrup or molasses. It is widely used in the food processing industry. Its core function is to dissolve sugar and remove water by heating to achieve a specific concentration. The most commonly used sugar boiling machine on the market is the scraper sugar boiling machine, which is a mechanical device that boils syrup by using a scraper to stir and heat the sugar.

[0003] The evaporation chamber of the scraper sugar boiling machine is equipped with multiple scraper sleeves concentrically fixed to the main shaft from top to bottom. Each scraper sleeve has multiple scrapers evenly distributed at equal angles along the circumference on its outer side. When the scraper sugar boiling machine is working, the syrup falls along the inner wall of the evaporation chamber onto the first scraper. The motor drives each scraper sleeve to rotate via the main shaft. The inertia of the rotation causes the scrapers to open, scraping the syrup on the inner wall of the evaporation chamber into a thin film for heating. At the same time, the heat generated when the evaporation chamber is heated is transferred to the sugar film, causing the water in the sugar film to vaporize and then be vacuumed away. The remaining syrup has increased concentration and specific gravity, and falls onto the next scraper, and so on, descending layer by layer.

[0004] However, the dehydration process of the scraper sugar boiling machine is inefficient, which leads to a long time for the entire sugar boiling process. Meanwhile, the energy input such as steam must be kept running at the same time, so the energy consumption is also high. In addition, the mixing between each layer of syrup is not uniform and there are differences in moisture content, resulting in poor dehydration effect, which urgently needs to be resolved.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This utility model utilizes a spiral guide channel to allow the syrup to gradually spiral upward during the heating process, removing moisture due to heat during the ascent. Since the spiral guide channel is composed of multiple interconnected spiral guide tubes arranged sequentially from top to bottom, and since the inner diameter of any single spiral guide tube is larger than the inner diameter of an adjacent spiral guide tube below it, the increased inner diameter of the spiral guide tubes leads to a larger inner wall area. This results in a progressively larger amount of syrup that can be held in each spiral guide tube, and a gradually increasing heating area, thus accelerating the heat conduction rate. This effectively speeds up the vaporization of moisture in the syrup, thereby significantly improving the dehydration efficiency and greatly shortening the time required for sugar boiling, while also effectively reducing energy consumption. Furthermore, the flowing syrup can be fully and evenly mixed and maintain a uniform moisture content, further enhancing the dehydration effect. Attached Figure Description

[0028] The cleaning module also includes a second drain pipe 320 and a second drain valve 321 connected in series with the second drain pipe 320. One end of the second drain pipe 320 is inserted into the second main air inlet pipe 311, and the other end of the second drain pipe 320 is inserted into the drain pipe 318 and located downstream of the second shut-off valve 319.

[0029] The vacuum system 2 also includes a condenser 25 connected in series with the outlet pipe 24.

[0030] Working principle: Turn on the sugar boiling pot and put all the ingredients for sugar boiling into the pot. The ingredients will slowly melt and mix to form syrup. Then, the syrup in the sugar boiling pot is transported to the sugar storage tank for later use by the transfer pump. The bottom of the sugar storage tank is then connected to the feed port of the metering pump 12 in the cooking system 1 through the pipeline.

[0031] After the metering pump 12 in the cooking system 1 is started, the syrup in the sugar storage tank will enter the lower opening of the lowest spiral guide pipe 151 in the spiral guide channel 15 through the feed pipe 13, and then flow upward step by step; after the pneumatic butterfly valve 16 is opened, the syrup coming out from the uppermost spiral guide pipe 151 will enter the vacuum tank 21 in the vacuum system 2 through the discharge pipe 14.

[0032] Before this, high-temperature steam is introduced into the air inlet of the first plunger valve 33 in the steam system 3 and the first plunger valve 33 is opened. The high-temperature steam will enter the first main air inlet pipe 31 through the first plunger valve 33. The second fine-tuning valve 37 and the second plunger valve 39 are closed and the first fine-tuning valve 34 and the proportional valve 310 are opened. The high-temperature steam will enter the heating tank 11 through the first branch air inlet pipe 32 and then transfer heat to each spiral guide pipe 151, thereby heating the syrup in each spiral guide pipe 151 to vaporize the water mixed in the syrup, thereby achieving the purpose of removing water. The vaporized water comes out along the spiral guide channel 15 and enters the vacuum tank 21 through the discharge pipe 14.

[0033] During the above process, the high-temperature steam in the heating tank 11 enters the annular insulation chamber 28 through the first outlet pipe 35, and then transfers heat to the vacuum tank 21, thereby keeping the syrup in the vacuum tank 21 warm to prevent solidification. The steam in the annular insulation chamber 28 returns to the boiler through the second outlet pipe 27 to achieve circulation.

[0034] Next, after the vacuum pump 23 in the vacuum system 2 is started, the vacuum pump 23 will generate negative pressure inside the vacuum tank 21 through the outlet pipe 24. Since the vaporized water entering the vacuum tank 21 will remain in the upper part of the vacuum tank 21, when negative pressure is generated inside the vacuum tank 21, the vaporized water will enter the outlet pipe 24. When the vaporized water flows through the condenser 25, it will liquefy into water and finally be discharged out through the outlet of the vacuum pump 23.

[0035] Finally, the unloading pump 22 can be started to output the dehydrated syrup, thus completing the sugar boiling process.

[0036] If the first sub-inlet pipe 32 or the first fine-tuning valve 34 malfunctions, the second fine-tuning valve 37 can be opened to allow the high-temperature steam in the first main inlet pipe 31 to enter the heating tank 11 through the second sub-inlet pipe 36; if both the first fine-tuning valve 34 and the second fine-tuning valve 37 malfunction, the second plunger valve 39 can be opened to allow the high-temperature steam in the first main inlet pipe 31 to be discharged through the third sub-outlet pipe 38, thereby preventing excessive pressure.

[0037] When the sugar boiling machine stops working and the heating tank 11 needs to be cleaned, the first fine-tuning valve 34, the second fine-tuning valve 37 and the second plunger valve 39 are closed, and the third plunger valve 313 and the first shut-off valve 315 in the cleaning module are opened. Then the first drain valve 317, the second shut-off valve 319 and the second drain valve 321 are closed. At this time, high-temperature steam will enter the second main air inlet pipe 311 through the transfer pipe 312, and then enter the lower part of the heating tank 11 through the third branch air inlet pipe 314, thereby cleaning the residual syrup adhering to the inner wall of the heating tank 11.

[0038] The steam after cleaning will liquefy and mix with the residual syrup to form sewage. At this time, the steam input is stopped and the third plunger valve 313 and the first shut-off valve 315 are closed. Then the first drain valve 317 and the second drain valve 321 are opened. The sewage will enter the first drain pipe 316 through the third air inlet pipe 314, and then enter the drain pipe 318 through the second drain pipe 320. Finally, it will be discharged outward through the drain pipe 318.

[0039] This invention utilizes a spiral guide channel 15 to allow the syrup to gradually spiral upward during heating, removing moisture as it rises. The spiral guide channel 15 is composed of multiple interconnected spiral guide tubes 151 arranged sequentially from top to bottom. Since the inner diameter of each spiral guide tube 151 is larger than the inner diameter of an adjacent spiral guide tube 151 located below it, the increased inner diameter of the spiral guide tubes increases the inner wall area, allowing each spiral guide tube 151 to hold a progressively larger amount of syrup. This also gradually increases the heating area and accelerates the heat conduction rate, effectively speeding up the vaporization of moisture in the syrup. This significantly improves the dehydration efficiency, substantially shortens the cooking time, and reduces energy consumption. Furthermore, the flowing syrup is thoroughly mixed and maintains a uniform moisture content, further enhancing the dehydration effect.
