Description

Technical Field

[0001] This application belongs to the field of food processing technology, specifically relating to a continuous charring device for syrups and sugar alcohols. Background Technology

[0002] In existing technologies, syrups and sugar alcohols have wide applications in the food and pharmaceutical industries. Decolorization is a crucial step in their production, typically achieved by adding activated charcoal. Current techniques generally involve manually adding activated charcoal to the sugar solution for direct decolorization; however, this process has several drawbacks.

[0003] In existing technologies, it is difficult to precisely control the amount of activated carbon added manually to the decolorization tank, which may lead to unsatisfactory decolorization results and affect the final quality of the syrup and sugar alcohol. Adding too much activated carbon is wasteful and increases production costs, while adding too little will not achieve the desired decolorization effect, requiring reprocessing and extending the production cycle. Secondly, manually adding activated carbon is inefficient and cannot meet the continuous requirements of large-scale production. During the production process, frequent pauses are needed to add activated carbon, which not only affects the production schedule but may also cause changes in the sugar solution temperature, thus affecting the stability of the product. In addition, existing decolorization devices also have some problems in the mixing and reaction process of activated carbon and sugar solution. For example, if the activated carbon is added too quickly, it is easy for the activated carbon to agglomerate in the decolorization tank, which can lead to local over- or under-decolorization, affecting the stability of product quality; moreover, the separation and recovery of activated carbon after the reaction is also difficult, which can easily lead to resource waste and environmental pollution.

[0004] Therefore, in order to solve the many problems existing in the activated carbon addition and decolorization process during the production of syrups and sugar alcohols in the current technology, and to improve production efficiency, product quality and safety, there is an urgent need to design a continuous activated carbon addition device for syrups and sugar alcohols to optimize the entire decolorization process. Utility Model Content

[0005] In order to solve the technical problems in the prior art, in the process of syrup production, activated carbon powder needs to be manually added to the decolorization tank for each decolorization process. It is difficult to accurately control the amount of activated carbon powder added during the feeding process. The activated carbon powder is prone to agglomeration during the feeding process, resulting in low production efficiency, inability to meet the needs of mass production, and poor product stability.

[0024] Combination Figure 1-5 The following description further illustrates the technical solution proposed in this application. This application provides a continuous charring device for syrups and sugar alcohols, including a charcoal mixing tank 1, a decolorizing tank 2 disposed on the charcoal mixing tank 1, and a conveying mechanism 3 disposed between the charcoal mixing tank 1 and the decolorizing tank 2. The charcoal mixing tank 1 has a first syrup inlet 10 and a charcoal powder inlet 11 at its top and a first outlet 12 at its bottom. The decolorizing tank 2 has a second syrup inlet 20 at its top and a decolorizing syrup inlet 21 and a second outlet 22 at its bottom. The conveying mechanism 3 is disposed between the first outlet 12 and the decolorizing syrup inlet 21.

[0025] This application provides a continuous activated carbon addition device for syrups and sugar alcohols, comprising a carbon mixing tank, a decolorizing tank mounted on the carbon mixing tank, and a conveying mechanism located between the carbon mixing tank and the decolorizing tank. The carbon mixing tank has a first syrup inlet and a carbon powder inlet at its top, and a first outlet at its bottom. The decolorizing tank has a second syrup inlet at its top, and a decolorizing syrup inlet and a second outlet at its bottom. The conveying mechanism is located between the first outlet and the decolorizing syrup inlet. By setting up the carbon mixing tank and the conveying mechanism, activated carbon powder and syrup can be premixed uniformly in the carbon mixing tank, avoiding the problems of carbon powder agglomeration and inaccurate dosage during manual feeding, effectively improving the utilization efficiency of activated carbon powder and the decolorization effect. After the decolorized syrup is prepared through premixing, continuous automatic addition of activated carbon powder can be achieved, greatly improving production efficiency, meeting the needs of mass production, and having the advantages of high product stability and ease of promotion and implementation.

[0026] In actual implementation, a metal sensor is also installed on the first syrup inlet to detect whether metal has been mixed into the syrup to be decolorized.

[0027] In actual implementation, such as Figure 5 As shown, the carbon mixing tank is connected to the decolorized syrup storage tank and the activated carbon powder storage tank respectively. Before the decolorization process, the decolorized syrup storage tank distributes the decolorized syrup A stream into the carbon mixing tank, and the activated carbon powder storage tank delivers activated carbon powder into the carbon mixing tank. After the first stirring mechanism mixes the two, the activated carbon powder is fully dispersed in the decolorized syrup to obtain decolorized syrup, which contains a high concentration of activated carbon powder.

[0028] During the decolorization process, the decolorized syrup storage tank distributes the decolorized syrup B stream into the decolorization tank. The conveying mechanism transports the decolorized syrup from the carbon mixing tank to the decolorization tank. The second stirring mechanism is used to stir the two evenly to achieve large-scale decolorization of the syrup.

[0029] In this embodiment, a first stirring mechanism 19 is also provided on the carbon mixing tank 1. The decolorized syrup A and activated carbon powder enter the carbon mixing tank 1 through the first syrup inlet 10 and the carbon powder inlet 11, respectively. The first stirring mechanism 19 is used to stir the decolorized syrup A and activated carbon powder into decolorized syrup. The conveying mechanism 3 is used to convey the decolorized syrup to the decolorized syrup inlet 21.

[0030] In this embodiment, a first filter assembly 4 is also provided in the carbon mixing tank 1 and located below the carbon powder inlet 11. The first filter assembly 4 is used to filter activated carbon powder.

[0031] In actual implementation, the median particle size of the activated carbon powder is defined as r, and the pore size of the filter holes on the first filter plate is defined as R. The relationship between R and r is: 3.5≤R / r≤5.5. By designing the relationship between the pore size of the filter holes on the first filter plate and the median particle size of the activated carbon powder, on the one hand, the throughput of activated carbon powder can be guaranteed while filtering large particles, avoiding material blockage. On the other hand, it avoids a large amount of activated carbon powder from coming into rapid contact with the sugar syrup A to be decolorized, effectively preventing the agglomeration of activated carbon powder, ensuring the dispersion stability of activated carbon powder, and increasing the concentration of activated carbon powder in the decolorized sugar syrup.

[0032] In this embodiment, the first filter assembly 4 includes a connecting flange 40 disposed on the inner wall of the carbon dispensing tank 1, and a first filter plate 41 mounted on the connecting flange 40.

[0033] In this embodiment, the conveying mechanism 3 includes a conveying pipe 30 located between the first outlet 12 and the decolorizing syrup inlet 21, a conveying pump 31 located on the conveying pipe 30, and a valve body 32 located on the side of the conveying pipe 30 near the first outlet 12. The conveying pump 31 is used to convey the decolorizing syrup in the charcoal mixing tank 1 to the decolorizing tank 2.

[0034] In this embodiment, the conveying mechanism 3 also includes a flow meter 33 disposed on the conveying pipe 30, which is used to measure the flow rate of the decolorizing syrup in the conveying pipe 30.

[0035] In actual implementation, the flow rate of decolorizing syrup in the delivery pipe is adjusted by regulating the opening of the valve body, and the flow rate of decolorizing syrup in the delivery pipe can be visualized by using a flow meter.

[0036] In this embodiment, a wear-resistant layer is also coated on the inner wall of the conveying pipe 30, and the wear-resistant layer is made of polytetrafluoroethylene.

[0037] In actual implementation, by setting a wear-resistant layer inside the conveying pipe, the service life of the conveyor can be effectively improved, and the activated carbon powder in the decolorizing syrup can be prevented from excessively abrading the conveying pipe.

[0038] In this embodiment, a first guide member 5 is provided on the first outlet 12, and a second guide member 6 is provided on the decolorizing syrup inlet 21. The first guide member 5 is used to guide the decolorizing syrup to the first outlet 12, and the second guide member 6 is used to guide the decolorizing syrup into the decolorizing tank 2.

[0039] In this embodiment, a second stirring mechanism 29 is also provided on the decolorizing tank 2. The syrup B to be decolorized enters the decolorizing tank 2 through the second syrup inlet 20. The second stirring mechanism 29 is used to mix the syrup B to be decolorized and the decolorizing syrup to decolorize the syrup B.

[0040] In this embodiment, a second filter assembly 7 is also provided on the second outlet 22. The second filter assembly 7 includes a housing 70 provided on the second outlet 22 and second filter plates 71 respectively provided at both ends of the housing 70. The material of the second filter plates 71 is polytetrafluoroethylene.

The carbon mixing tank has a first syrup inlet and a carbon powder inlet at its top, and a first outlet at its bottom. The decolorizing tank has a second syrup inlet at its top, and a decolorizing syrup inlet and a second outlet at its bottom. The conveying mechanism is located between the first outlet and the decolorizing syrup inlet. By setting up the carbon mixing tank and the conveying mechanism, activated carbon powder and syrup can be premixed uniformly in the carbon mixing tank, avoiding the problems of carbon powder agglomeration and inaccurate dosage during manual feeding, effectively improving the utilization efficiency of activated carbon powder and the decolorization effect. After the decolorized syrup is prepared through premixing, continuous automatic addition of activated carbon powder can be achieved, greatly improving production efficiency, meeting the needs of mass production, and having the advantages of high product stability and ease of promotion and implementation.
