Description

Technical Field

[0001] This utility model relates to a mixing and drying device for low-GI compound sugars, belonging to the technical field of material mixing and drying equipment. Background Technology

[0002] In the production of L-arabinose compound sugars, existing mixing methods have significant drawbacks. For example, in dry mixing, due to the different particle sizes of L-arabinose and other sugars, smaller L-arabinose particles tend to sink to the bottom of the packaging during handling or use, resulting in insufficient proportions of the compound sugar in certain areas and failing to meet the low-GI requirements for some regions. Simultaneously, in wet mixing, because of the low solubility of L-arabinose, when the amount of L-arabinose solid solution added at one time reaches 6%, the moisture content of the compound sugar can reach as high as 11% in a 50°C L-arabinose solution environment. This causes a large amount of sucrose crystals to dissolve, making drying impossible and failing to meet the crystal size requirements of the dried compound sugar. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing and drying device for low-GI compound sugars. This device avoids the problem of insufficient proportions in certain areas due to differences in particle size during mixing, ensuring that the proportions of each part of the compound sugar are uniform and meeting the requirements for low-GI compound sugars.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A mixing and drying apparatus for low-GI compound sugars includes a vertical vibrating lift dryer and a drying chamber. The vertical vibrating lift dryer includes a casing, with a vertically installed air supply pipe I inside the casing. A spiral conveying trough is provided on the outer side of the air supply pipe I. An air inlet is provided on the bottom side of the air supply pipe I, and several air outlets I are opened on the side of the air supply pipe I. The bottom of the casing has a feed inlet I and a transfer outlet, through which the material enters the casing and falls into the spiral conveying trough. The upper side of the casing has a discharge outlet I, and the outlet of the spiral conveying trough is connected to the discharge outlet I. A vibration motor is provided at the top of the casing to drive the air supply pipe I and the spiral conveying trough to vibrate. Several nozzles are provided on the inner side wall of the middle part of the casing, and a sugar syrup conveying pipe is provided on the outer side of the casing. One end is connected to a sugar syrup delivery pump, and the other end is connected to a nozzle; the top of the drying chamber is provided with a feed inlet II and an air outlet I, the feed inlet II is connected to the discharge outlet I of the casing through a pipe; the bottom of the drying chamber is provided with a discharge outlet II, the discharge outlet II is connected to a discharge valve, the outlet of the discharge valve is connected to a bend, a vibrating conveyor is provided below the discharge outlet II, and the transfer port of the casing is located below the discharge outlet II; the middle and lower part of the drying chamber is provided with a hollow cone, and an air supply pipe II is connected to each of the four sides of the cone; one end of the air supply pipe II is connected to the cone, and the other end is connected to the inner wall of the drying chamber, and one of the air supply pipes II passes through the drying chamber and connects to the air supply pipe III; a number of air outlets II are evenly provided on the upper surface of the cone, and a number of air outlets III are provided on the upper surface of the air supply pipe II.

[0005] Furthermore, both the feed inlet and the transfer outlet are connected to receiving funnels.

[0006] Furthermore, the discharge port II is connected to an electric three-way distributor. The inlet of the electric three-way distributor is connected to the discharge port II. One outlet of the electric three-way distributor is located above the transfer port of the machine casing, and the other outlet is located above the inlet of the vibrating conveyor. The electric three-way distributor facilitates switching the material conveying position and can promptly convey the material to the vertical vibrating lift dryer or vibrating conveyor according to the actual situation.

[0007] Furthermore, the nozzle is divided into two nozzle groups, which are arranged vertically. Each nozzle group contains several nozzles, and the nozzles of each nozzle group are arranged in a ring along the inner wall of the machine casing. By setting multiple sets of nozzles, the material can be effectively sprayed into the vertical vibrating lift dryer and mixed evenly with the material inside the machine.

[0008] Furthermore, the bottom of the drying chamber is inverted conical in shape, and the discharge port II is located at the lowest point. This design facilitates the discharge of materials from the drying chamber.

[0009] Compared with the existing technology, the present technical solution has the following beneficial effects: 1. The mixing and drying device for low-GI compound sugars described in this utility model includes a drying chamber and a vertical vibrating elevator dryer, which form a circulating drying path. The drying chamber can return the material to the vertical vibrating elevator dryer, enabling the material to circulate and dry, ensuring thorough and uniform drying. Furthermore, a spraying device is installed in the vertical vibrating elevator dryer for spraying L-arabinose syrup. Specifically, L-arabinose syrup is added in proportion through nozzles and uniformly mixed with other sugar particles before drying. Precise spraying through nozzles ensures that the moisture content is within an appropriate range, achieving effective adsorption of L-arabinose and meeting the final moisture content standard, thus solving the problems of dry mixing and traditional wet mixing.

[0010] 2. This device uses wet mixing and drying, allowing L-arabinose to recrystallize and adsorb firmly onto the surface of sucrose crystals after dehydration. This avoids the problem of insufficient proportion in certain areas due to differences in particle size during dry mixing, ensuring that the proportions of each part of the compound sugar are uniform and meeting the low GI requirements.

[0011] 3. Precisely controlling the spraying speed of L-arabinose syrup in the vertical vibration lifting dryer ensures that the moisture content of the compound sugar is within a suitable range, preventing excessive dissolution of sucrose crystals, guaranteeing the required crystal size of the compound sugar, and maintaining good fluidity for easy subsequent packaging, handling, and use.

The inlet II14 is connected to the discharge port I9 of the housing 1 through a pipe; the bottom of the drying chamber 2 is provided with a discharge port II, which is connected to a discharge outlet. Valve 16, the outlet of the discharge valve 16 is connected to a bend 17, the connection between the outlet of the discharge valve 16 and the bend 17 can be a flange connection or a rotary joint connection, a vibrating conveyor 22 is provided below the discharge port II, the transfer port 8 of the housing 1 is located below the discharge port II; a hollow cone 18 is provided in the middle and lower part of the drying chamber 2, and an air supply pipe II 19 is connected to each of the four sides of the cone 18; one end of the air supply pipe II 19 is connected to the cone 18, and the other end is connected to the inner wall of the drying chamber 2, and one of the air supply pipes II 19 passes through the drying chamber 2 and is connected to the air supply pipe III; The upper surface of the cone 18 is uniformly provided with a plurality of air outlets II 20, and the upper surface of the air supply pipe II 19 is provided with a plurality of air outlets III 21; the nozzle 11 is divided into two groups of nozzles 11, and the two groups of nozzles 11 are arranged vertically, each group of nozzles 11 contains a plurality of nozzles 11, and the nozzles 11 of each group of nozzles 11 are arranged in a ring along the inner wall of the casing 1.

[0017] The working process of the mixing and drying device for low-GI compound sugars described in this embodiment is as follows: Before use, the vertical vibration lifting dryer, drying chamber 2, and vibrating conveyor 22, etc., should be debugged and powered. In use, the vibration motor 10 of the vertical vibration lifting dryer is turned on and the material, such as sucrose granules, is fed in through the feed port I7 of the casing 1. At the same time, hot air is fed in through the air inlet 5 at the bottom of the air supply pipe I3 ​​by the hot air blower. The fed material moves from bottom to top along the spiral conveyor 4 under the action of vibration. The hot air is blown out from the air outlet I6 on the side of the feed pipe I and comes into contact with the material to heat the material, thereby drying the material. In addition, the sugar solution conveying pump 13 is turned on to send the sugar solution of L-arabinose through the sugar solution conveying pipe 12 to the nozzle 11 on the side wall of the casing 1 and spray it into the casing 1 to mix with the material on the spiral conveyor 4 and dry it. After drying, the material moves to the top of the spiral conveyor trough 4 and enters the drying chamber 2 through the discharge port I9 and the inlet II14 of the drying chamber 2. At the same time, the hot air in the casing 1 enters the drying chamber 2 through the discharge port I9 and the inlet II14 of the drying chamber 2, and then exits from the air outlet I15 of the drying chamber 2. Meanwhile, hot air is supplied to the drying chamber 2 through the air supply pipe II19 and the cone 18 by the hot air blower. Specifically, the hot air is blown into the drying chamber 2 from the air outlet II20 of the cone 18 and the air outlet III21 of the air supply pipe II19. The material entering the drying chamber 2 comes into contact with the hot air in the drying chamber 2 for further drying, and then falls to the bottom of the drying chamber 2 and is discharged through the discharge port II onto the vibrating conveyor 22. The vibrating conveyor 22 sends the material to the next process, such as the packaging process. If the material in drying chamber 2 does not meet the production requirements, that is, the sugar content in the low-GI compound sugar obtained in drying chamber 2 is not up to standard, the elbow at the discharge port II of drying chamber 2 is turned to the transfer port 8 at the casing 1 of the vertical vibration lifting dryer, the material in drying chamber 2 is conveyed to the transfer port 8, and then re-enters the spiral conveyor trough 4 in the casing 1 through the transfer port 8 to re-mix the L-arabinose sugar solution and dry it.
