Description

Technical Field

[0001] This utility model relates to a sugar dissolving device, belonging to the technical field of dissolving equipment. Background Technology

[0002] In the sugar dissolution process, especially in the dissolution of brown sugar, the low purity, low pH value and high moisture content of brown sugar make it very easy to clump and discolor during storage. At the same time, because brown sugar is difficult to break and dissolve, it is difficult to achieve large-scale redissolution and purification. It can only be used as a low-value raw material for the production of feed, alcohol and other products.

[0003] Existing sugar dissolving equipment suffers from numerous efficiency problems when applied to brown sugar dissolving. These include adhesion to the conveying equipment, preventing proper delivery to the dissolving tank; insufficient mixing with water in traditional raw sugar dissolving equipment, leading to sedimentation that damages the stirring blades and negatively impacting the equipment and dissolving effect. Furthermore, the structural design, stirring methods, and feeding methods of existing sugar dissolving equipment are not adapted to the characteristics of brown sugar, resulting in low dissolving efficiency, incomplete dissolution, and localized clumping. Simultaneously, the unsuitable dissolving process increases the operating load on the equipment, potentially causing accelerated wear of equipment components, increased energy consumption, shortened equipment lifespan, and impacting overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sugar dissolving device that solves problems such as obstructed transport, insufficient mixing, low dissolving efficiency, and high equipment wear when using existing dissolving devices for dissolving brown sugar.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sugar dissolving device includes a dissolving tank, a feed hopper, a conveying pump, a reflux pump, a steam injection pipe, and a hot water injection pipe. The dissolving tank has a feed inlet at one top end and an overflow outlet on the upper side of the other end. The interior of the dissolving tank is divided into a primary dissolving zone, a secondary dissolving zone, a tertiary dissolving zone, and a quaternary dissolving zone by primary, secondary, and tertiary partitions from the feed inlet to the overflow outlet. The height of the primary partition is greater than that of the secondary partition, and the height of the secondary partition is greater than that of the tertiary partition. A stirring motor is located on one side of the dissolving tank. A stirring shaft is horizontally arranged inside the dissolving tank, with one end passing through the dissolving tank and connected to the rotating shaft of the stirring motor. Several stirring paddles are mounted on the stirring shaft. The outlet of the feed hopper is connected to the feed inlet of the dissolving tank. The feed hopper has several hot water nozzles and several return nozzles on its side wall; one end of the hot water injection pipe is connected to the hot water delivery pump, and the other end is connected to the hot water nozzle; the inlet of the hot water delivery pump is connected to the hot water pipe network through a pipe; the inlet of the return pump is connected to the overflow port of the dissolving tank through a pipe, and the outlet of the return pump is connected to the return nozzle through a pipe; the inlet of the conveying pump is connected to the overflow port of the dissolving tank through a pipe, and the conveying pump is used to convey the material in the dissolving tank to the next processing step; there are two steam injection pipes, one of which is connected to the steam pipe network at one end and extends along the first-stage baffle to the bottom of the dissolving tank at the other end, and the other of which is connected to the steam pipe network at one end and extends along the third-stage baffle to the bottom of the dissolving tank at the other end.

[0006] Furthermore, a curved screen is provided at the top of the three-stage partition between the three-stage dissolving zone and the four-stage dissolving zone. The curved screen can effectively filter out foreign objects (such as impurities, packaging fragments, etc.) that may be introduced during the unpacking process, preventing foreign objects from entering subsequent processes and affecting the purity of the syrup or damaging the equipment.

[0007] Furthermore, the number of agitators located in the primary dissolution zone is greater than the number of agitators in other dissolution zones.

[0008] Furthermore, the number of agitators in the primary dissolving zone is twice the number in the secondary dissolving zone. Materials such as granulated sugar or brown sugar are first added to the primary dissolving zone for stirring and dissolution. The increased number of agitators effectively disperses the sugar particles and promotes dissolution.

[0009] Furthermore, the discharge port of the feed hopper and the feed port of the dissolving tank are connected by an inclined chute.

[0010] Furthermore, the chute is inclined at 45 degrees. Arranging the chute at an appropriate angle allows the material to enter the dissolving tank quickly without accumulating or clogging.

[0011] Furthermore, the reflux nozzles and hot water nozzles are arranged alternately; that is, the reflux nozzles are first arranged in a ring on the side wall of the feed hopper, and then a hot water nozzle is arranged between two adjacent reflux nozzles. The ring-arranged nozzles spray hot water or reflux sugar solution from multiple directions, promoting uniform mixing with the sugar material.

[0012] Compared with existing technologies, this technical solution has the following beneficial effects: 1. This equipment adopts a four-stage progressive dissolution process with a circulating reflux design, which allows the brown sugar to be gradually and fully mixed with the solvent in stages of dissolution, avoiding the problems of excessively high local concentration and incomplete dissolution in traditional single-stage dissolution; the annular multi-point spray device in the feed hopper of the first-stage dissolution zone pre-mixes the brown sugar into a paste, reducing the formation of lumps from the source and greatly improving the overall dissolution efficiency.

[0013] 2. The curved sieve structure set between the three-stage and four-stage dissolving zones can effectively filter foreign objects (such as impurities and packaging fragments) introduced during the unpacking process, reduce the interference of impurities on subsequent processes, and improve the purity of syrup. At the same time, by controlling the amount of re-dissolving and the dissolving rhythm, the effective components in brown sugar are avoided from being damaged due to over-processing, and the quality stability of the syrup after dissolution is guaranteed.

[0014] 3. A chute is connected to the outlet of the feed hopper to prevent dry brown sugar from flowing directly into the dissolving tank in large quantities, causing equipment blockage and impact wear. At the same time, the sugar solution is circulated back by the return nozzles and return pumps installed on the feed hopper, thereby reducing the ineffective load on the stirring device. Combined with the reasonable distribution of energy through staged dissolving, the wear rate of equipment parts is reduced, the service life of the equipment is extended, and energy waste is reduced.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments. Specific experimental conditions and methods not specified in the following embodiments are generally conventional methods well known to those skilled in the art.

[0019] Example 1: As shown in the attached document Figure 1 As shown, a sugar dissolving device includes a dissolving tank 1, a feed hopper 2, a feed pump 3, a reflux pump 4, a steam injection pipe 5, and a hot water injection pipe 6. The dissolving tank 1 has a feed inlet at one top end and an overflow outlet 18 on the upper side of the other end. The interior of the dissolving tank 1 is divided into a primary dissolving zone 14, a secondary dissolving zone 15, a tertiary dissolving zone 16, and a quaternary dissolving zone 17 by a primary partition 11, a secondary partition 12, and a tertiary partition 13, running from the feed inlet to the overflow outlet 18. The height of the primary partition 11 is greater than that of the secondary partition 12. The height of partition 12 is greater than that of the third-stage partition 13; a stirring motor 7 is provided on one side of the dissolving tank 1, and a stirring shaft 71 is horizontally arranged inside the dissolving tank 1. The stirring shaft 71 passes through the third-stage partition 13, the second-stage partition 12, and the first-stage partition 11 in sequence. One end of the stirring shaft 71 passes through the dissolving tank 1 and is connected to the rotating shaft of the stirring motor 7. Ten stirring paddles 72 are provided on the stirring shaft 71; the outlet of the feed hopper 2 is connected to the feed inlet of the dissolving tank 1, and several hot water nozzles 21 and several return nozzles 22 are provided on the side wall of the feed hopper 2; the hot water... One end of the injection pipe 6 is connected to the hot water delivery pump 61, and the other end is connected to the hot water nozzle 21. The inlet of the hot water delivery pump 61 is connected to the hot water pipe network 62 through a pipe. The inlet of the return pump 4 is connected to the overflow port 18 of the dissolving tank 1 through a pipe, and the outlet of the return pump 4 is connected to the return nozzle 22 through a pipe. The inlet of the feed pump 3 is connected to the overflow port 18 of the dissolving tank 1 through a pipe. The feed pump 3 is used to transport the material in the dissolving tank 1 to the next processing step. There are two steam injection pipes 5, one end of which is connected to the steam pipe network. One end of the first-stage partition 11 extends into the bottom of the dissolving tank 1, and the other end is connected to the steam pipe network 51. The other end extends into the bottom of the dissolving tank 1 along the third-stage partition 13. A curved screen 19 is provided on the top of the third-stage partition 13 between the third-stage dissolving zone 16 and the fourth-stage dissolving zone 17. The number of stirring paddles 72 in the first-stage dissolving zone 14 is twice the number of stirring paddles 72 in the second-stage dissolving zone 15. The outlet of the feed hopper 2 and the inlet of the dissolving tank 1 are connected by an inclined chute 23 with an inclination of 45 degrees.

[0020] The method of using the sugar dissolving device described in this embodiment is as follows: Before use, connect the stirring motor 7 and pump in the equipment to the power supply and perform debugging. Then, feed the dried brown sugar into the dissolving tank 1 through the feed hopper 2. Simultaneously, turn on the stirring motor 7 to drive the stirring shaft 71 and stirring paddle 72 to rotate and uniformly stir the material in the dissolving tank 1. Turn on the hot water delivery pump 61 to spray pure hot water through the hot water injection pipe 6 and then through the hot water nozzle 21 into the feed hopper 2 to mix with the dried brown sugar. One steam injection pipe 5 injects pure steam into the primary dissolving zone 14 and secondary dissolving zone 15 of the dissolving tank 1 to heat the material and promote the dissolution of the brown sugar. The other steam injection pipe 5 injects pure steam into the tertiary dissolving zone 16 of the dissolving tank 1. The brown sugar material is dissolved into a syrup and flows sequentially through the first-stage dissolving zone 14, the second-stage dissolving zone 15, and the third-stage dissolving zone 16. After passing through the curved screen 19 to filter impurities, it flows to the fourth-stage dissolving zone 17. Brown sugar is continuously added to the dissolving tank 1, increasing the amount of dissolved sugar solution and raising the sugar solution level. When the sugar solution level exceeds the overflow port 18 of the dissolving tank 1, the feed pump 3 can be activated to send the dissolved sugar solution to the next process for further processing. The continuous addition of brown sugar to the dissolving tank 1 for dissolution and continuous production of sugar solution achieves continuous production of the brown sugar dissolution process. In addition, a portion of the sugar solution can be drawn from the overflow port 18 of the dissolving tank 1 by the reflux pump 4 and transported to the reflux nozzle 22 of the feed hopper 2. The reflux solution is then sprayed into the feed hopper 2 to mix with the brown sugar and undergo re-dissolution. The reflux flow rate can be set to 1 to 2 times the amount dissolved. The circulating flushing enhances the dissolution effect and ensures uniform syrup concentration.

[0021] Example 2: The only difference between the sugar dissolving device described in this example and the device described in Example 1 is that the reflux nozzle 22 and the hot water nozzle 21 are arranged alternately. That is, the reflux nozzle 22 is first arranged in a ring on the side wall of the feed hopper 2, and then a hot water nozzle 21 is arranged between two adjacent reflux nozzles 22. Hot water or reflux sugar solution is sprayed in from multiple directions through the ring-arranged nozzles, which can promote the uniform mixing of them with the sugar material.
