Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a closed-type automatic reprocessing device for sugar powder. Background Technology

[0002] Glucose, a fine chemical widely used in food, pharmaceuticals, cosmetics, and other fields, requires strict purity and quality control. The quality of these components directly impacts product performance, safety, and market competitiveness. High-purity edible glucose ensures product stability and consistency, enhancing its performance across various applications. In terms of quality control, the production of edible glucose requires adherence to a series of stringent standards and procedures, starting with the selection of raw materials to ensure their high quality and lack of contamination.

[0003] The glucose production process includes: after the separated glucose crystals undergo decolorization, crystallization, and separation, glucose monohydrate crystals are obtained. The glucose monohydrate crystals need to be dried in an airflow drying system and finally screened to obtain the finished glucose product.

[0004] During the above process, fine powder will be generated in the airflow drying system (cyclone dust collector, drying tower); powder that cannot be screened out will also appear during the sieving process; fine powder and powder on the sieve need to be recycled and reworked to continue glucose production.

[0005] In existing recycling and rework processes, fine powder is directly absorbed into a filter bag through a pipe, and sieve powder is also absorbed into the filter bag through an auger. The filter bag is then manually removed and transported to the decolorization process. The fine powder and sieve powder in the filter bag are then manually poured into the decolorization tank for rework.

[0006] The aforementioned manual disassembly and transfer of the cloth bags carries the risk of contamination of fine powder and powder on the sieve, making it difficult to control purity and affecting the purity and quality of glucose, which does not meet the standards and requirements for glucose production.

[0007] Furthermore, because fine powder and sieve powder are very prone to clumping and are difficult to dissolve, the fine powder and sieve powder generated in the production workshop must be reworked within 24 hours. However, the existing bag recycling operation is generally carried out by shift (for example, an 8-hour workday is a shift) for unified transfer and rework. The collection volume of a single shift in the production workshop reaches more than 40 bags, so the collection volume of fine powder and sieve powder is very large. If a large amount of fine powder and sieve powder is put into the decolorization process for rework at once, it is difficult for the decolorization tank to re-dissolve it.

[0008] Deficiencies of existing technology:

[0009] 1. Using manual collection for rework is inefficient and increases production costs.

[0010] 2. Impurities or contamination can easily be introduced during rework, affecting the purity of the product and leading to a decline in product quality.

[0011] 3. It cannot achieve automation and continuous rework.

[0012] Patent CN201272756Y discloses a sugar powder recovery device in an anhydrous glucose fluidized bed drying process. This device recovers sugar powder by repeatedly spraying gas containing sugar powder into water, causing the sugar powder to dissolve. However, this technology can only recover sugar powder from the gas; it cannot recover or dissolve larger particles of powder remaining on the sieve. Therefore, this technology still has shortcomings. Utility Model Content

[0013] In view of this, this utility model proposes a closed-loop automatic reprocessing device for powdered sugar to solve the problems of easy contamination and difficulty in dissolving fine powder and powder on sieves in the prior art.

[0014] The technical solution of this utility model is implemented as follows:

[0015] This utility model provides a closed-type automatic reprocessing device for sugar powder, including a sugar dissolving tank, an internal stirring structure, a heating structure, a cyclone dust collector, a drying tower, and a gyratory screen connected forward, and a decolorizing tank connected backward; the heating structure includes a hot water pipe extending into the sugar dissolving tank and connected to a water heater; the stirring structure includes a stirring rod disposed inside the sugar dissolving tank, and several sets of stirring paddles disposed on the stirring rod.

[0016] Based on the above technical solutions, the preferred connection method between the sugar dissolving tank and the cyclone dust collector and drying tower is as follows: the top of the sugar dissolving tank is connected to a sugar powder pipe, which is connected to the cyclone dust collector and the drying tower respectively; an air pump is also installed on the sugar powder pipe.

[0017] Based on the above technical solutions, the preferred connection method between the sugar dissolving tank and the gyratory screen is as follows: the sugar dissolving tank is connected to an auger, and the gyratory screen is connected through the auger.

[0018] Based on the above technical solutions, the preferred connection method between the sugar dissolving tank and the decolorizing tank is as follows: the sugar dissolving tank is first connected to the transfer tank, and then connected to the decolorizing tank through the sugar dissolving pump.

[0019] Based on the above technical solutions, preferably, the sugar dissolving tank is equipped with a sealing structure.

[0020] Based on the above technical solutions, preferably, the sealing structure includes a lid, which is sealed to the top of the sugar dissolving tank, and sealing rings are provided at the connections between the lid and the sugar powder pipe and the hot water pipe.

[0021] Based on the above technical solutions, the preferred option is to also provide an inspection port on the tank lid.

[0022] Based on the above technical solutions, preferably, the sugar dissolving tank is also equipped with a level gauge.

[0023] The closed-type automatic reprocessing device for powdered sugar of this invention has the following advantages over the prior art:

[0024] The structure of this invention is relatively simple, but in the glucose production process, it can simultaneously collect and dissolve fine powder and powder on the sieve.

[0025] Because the fine powder and sieve powder are continuously fed into the sugar dissolving tank, rather than being dissolved all at once, even though the output of a shift is large, it is still possible to achieve good dissolution of the fine powder and sieve powder.

[0026] Because the entire rework process is sealed, both fine powder and sieve powder can be dissolved and mixed in a sealed environment without the risk of pollution, thus achieving purity control and meeting the standards and requirements for glucose production.

[0027] The entire rework process requires no manual operation, achieving automated and continuous rework, simplifying the operation process, reducing labor costs, and improving work efficiency. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] The closed-loop automatic reprocessing device for sugar powder of this utility model includes a sugar dissolving tank 1, which has an internal stirring structure. The sugar dissolving tank 1 is connected to a heating structure and is also connected forward to a cyclone dust collector 52, a drying tower 53, and a gyratory screen 6, and backward to a decolorizing tank 72. The processes of the cyclone dust collector 52, the drying tower 53, and the gyratory screen 6 are all before the sugar dissolving tank 1. Although the decolorizing process in the decolorizing tank 72 is an upstream process in glucose production, in the automatic reprocessing of sugar powder, the decolorizing process is located after the sugar dissolving tank 1.

[0033] In this utility model, the sugar dissolving tank 1 is made of high-quality stainless steel, which has the characteristics of corrosion resistance and high temperature resistance.

[0034] The heating structure includes a hot water pipe 3 that extends into the sugar dissolving tank 1 and is connected to a water heater 31. The water is heated by the water heater 31 and introduced into the sugar dissolving tank 1 through the hot water pipe 3 to dissolve the fine powder and sieve powder in the sugar dissolving tank 1.

[0035] The stirring structure includes a stirring rod 2 disposed inside the sugar-dissolving tank 1, with several sets of stirring paddles 21 mounted on the stirring rod 2, and a motor connected to the top of the stirring rod 2. In this invention, three sets of stirring paddles 21 are provided, with the highest set positioned at half the height of the sugar-dissolving tank 1. The arrangement of the three sets of stirring paddles 21 achieves efficient and uniform mixing. Since the solution volume inside the sugar-dissolving tank 1 is generally controlled at half the height of the tank 1 to prevent excessive overflow, the stirring paddles 21 are all located below half the height of the sugar-dissolving tank 1. Under normal circumstances, hot water (deionized water) can dissolve fine powders, but the powder on the sieve is generally larger. The stirring action of the stirring paddles 21, combined with hot water, can accelerate the dissolution of the powder on the sieve.

[0036] The sugar dissolving tank 1 is connected to the cyclone dust collector 52 and the drying tower 53 as follows: the top of the sugar dissolving tank 1 is connected to the sugar powder pipe 5, which is connected to both the cyclone dust collector 52 and the drying tower 53; an air pump 51 is also installed on the sugar powder pipe 5. The air pump 51 collects the fine powder generated in the cyclone dust collector 52 and the drying tower 53 and introduces it into the sugar dissolving tank 1 for dissolution.

[0037] The sugar dissolving tank 1 is connected to the gyratory screen 6 as follows: the sugar dissolving tank 1 is connected to the auger 61, and the gyratory screen 6 is connected through the auger 61; since the powder particles on the gyratory screen 6 are relatively large, the powder particles on the auger are introduced into the sugar dissolving tank 1 through the auger.

[0038] The sugar dissolving tank 1 and the decolorizing tank 72 are connected as follows: the sugar dissolving tank 1 is first connected to the transfer tank 71, and then connected to the decolorizing tank 72 through the sugar dissolving pump 7. The sugar solution that has been dissolved in the sugar dissolving tank 1 is first filtered through a filter plate to remove residue, and then enters the transfer tank 71 for buffering. After buffering, it is introduced into the decolorizing tank 72 through the sugar dissolving pump 7 for decolorization treatment.

[0039] In this invention, the sugar-dissolving tank 1 is equipped with a sealing structure. The sealing structure includes a lid 11, which is sealed to the top of the sugar-dissolving tank. Sealing rings 13 are provided at the connections between the lid 11 and the sugar powder pipe 5 and the hot water pipe 3. The sealing rings 13 ensure that the sugar-dissolving tank 1 is sealed, effectively preventing the entry of external contaminants, ensuring a pollution-free dissolving process, and controlling the purity of the sugar solution. In this invention, the lid 11 also has an inspection port 12 for cleaning and maintaining the sugar-dissolving tank 1, and a sealing ring 13 is also provided around the inspection port 12.

[0040] In this invention, a level gauge 4 is also provided on the sugar dissolving tank 1, and the level gauge 4 is located at one-half to two-thirds of the height of the sugar dissolving tank 1.

[0041] The glucose production process also includes an automatic control program. The level gauge 4 and the sugar-dissolving pump 7 are electrically connected to this program. Hot water from the hot water pipe 3, fine powder from the cyclone dust collector 52 and drying tower 53, and powder from the sieve on the gyratory screen 6 continuously enter the sugar-dissolving tank 1. Under the combined action of the hot water and the stirring paddle 21, the fine powder and sieve powder are dissolved. When the dissolved sugar solution reaches the level gauge 4, the level gauge 4 transmits a signal to the automatic control program. The automatic control program then controls the sugar-dissolving pump 7 to open, introducing a certain amount of sugar solution into the decolorization tank 72 for reprocessing. After the sugar-dissolving pump 7 has operated for a predetermined time, the sugar solution in the sugar-dissolving tank 1 falls below the level gauge 4, and the automatic control program controls the sugar-dissolving pump 7 to close. The hot water from the hot water pipe 3, the fine powder from the cyclone dust collector 52 and drying tower 53, and the sieve powder from the gyratory screen 6 continue to enter the sugar-dissolving tank 1, thus completing the cycle.

[0042] 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.
