Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to chitosan oligosaccharide extraction and drying equipment. Background Art

[0002] Chitosan oligosaccharide, also known as chitosan oligosaccharide or low-molecular-weight chitosan, is an oligosaccharide product with a degree of polymerization between 2 and 20 obtained by degrading chitosan through special bio-enzyme technology. Its molecular weight is ≤3200Da. It is a low molecular weight product with good water solubility, great functional effects and high biological activity. Chitosan oligosaccharide is usually made through processes such as degradation, separation and drying. Traditional oligosaccharide extraction and drying equipment cannot make chitosan oligosaccharide fully contact with hot air, which reduces the drying effect.

A plurality of stirring rods 32 are fixedly mounted on the outer side wall of the rotating rod 31 and inside the drying oven 2. A motor 33 for driving the rotating rod 31 to rotate is fixedly mounted on the top of the drying oven 2. During use, the motor 33 is controlled to start. The output shaft of the motor 33 rotates, driving the rotating rod 31 to rotate on the drying oven 2, and the plurality of stirring rods 32 rotate around the rotating rod 31, so as to stir the chitosan oligosaccharide fed into the drying oven 2.

A hot air blower 42 is fixedly mounted on the outer side wall of the drying oven 2. A connecting pipe 43 is fixedly mounted on the air outlet end of the hot air blower 42. The other end of the connecting pipe 43 penetrates the drying oven 2 and is communicated with the ventilation pipe 41. A plurality of air outlet pipes 44 communicated with the inside of the ventilation pipe 41 are fixedly mounted at the bottom of the ventilation pipe 41 in a circumferential array along the axis of the rotating rod 31. A plurality of air outlet holes 441 communicated with the inside of the air outlet pipes 44 are formed in the air outlet pipes 44. During use, the hot air blower 42 is controlled to start. The hot air blower 42 works to blow hot air into the connecting pipe 43, which is then conveyed through the ventilation pipe 41 to the plurality of air outlet pipes 44, and then discharged through the air outlet holes 441 on the air outlet pipes 44, so as to be dispersed and blown onto the chitosan oligosaccharide in the drying oven 2 to dry the chitosan oligosaccharide.

[0043] Embodiment Three

[0044] As Figure 1-Figure 5 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0045] In this embodiment, the filter assembly 5 includes a mounting frame 51 fixedly mounted on the feeding hopper 21, one end of the mounting frame 51 extends to the top of the feeding hopper 21 and is hinged with a mounting plate 53 that can fit with the top of the feeding hopper 21 through a hinge shaft 52, the mounting plate 53 is provided with a through hole 531 that can communicate with the feeding hopper 21, a filter plate 54 is fixedly mounted on the mounting plate 53 and located in the through hole 531, a worm gear 55 is coaxially fixed on the hinge shaft 52, and a worm 56 that meshes with the worm gear 55 is rotatably mounted on the feeding hopper 21. When in use, when chitosan oligosaccharides are fed into the drying oven 2, the rotating worm 56 drives the hinge shaft 52 through the worm gear 55 to rotate. The mounting frame 51 is rotated to move the mounting plate 53 to one side of the feeding hopper 21, so that the blockage of the open end of the feeding hopper 21 can be removed, and the chitosan oligosaccharide can be fed into the feeding hopper 21. After the feeding is completed, the rotating worm 56 drives the hinge shaft 52 to rotate on the mounting frame 51 through the worm gear 55, thereby driving the mounting plate 53 to rotate around the hinge shaft 52 and fit the top of the feeding hopper 21. At this time, the through hole 531 is connected to the feeding hopper 21. When the hot air is discharged through the feeding hopper 21, it is discharged through the through hole 531, so that the chitosan oligosaccharide powder can be filtered through the filter plate 54, effectively avoiding the chitosan oligosaccharide powder from being discharged through the through hole 531, resulting in a waste of chitosan oligosaccharide powder.

[0046] In the present embodiment, a slot 532 connected to the inside of the through hole 531 is provided on one side of the mounting plate 53 and located above the filter plate 54. A blocking plate 6 for blocking the through hole 531 is inserted on the mounting plate 53 and located in the slot 532. The blocking plate 6 is in contact with the inner wall section of the slot 532. By setting the blocking plate 6, when the chitosan oligosaccharide fed into the drying box 2 is dried, the blocking plate 6 is pushed to be inserted into the slot 532 to block the through hole 531. When unloading, the hot air blower 42 can be controlled to work and deliver hot air into the drying box 2. At this time, the hot air is discharged through the discharge pipe 22, thereby driving the chitosan oligosaccharide powder in the drying box 2 to flow toward the discharge pipe 22, which is beneficial to unloading the chitosan oligosaccharide powder in the drying box 2.

[0047] In the present embodiment, an air inlet pipe 7 is fixedly installed at the air inlet end of the hot air blower 42, and a dust removal assembly 8 is installed on the air inlet pipe 7. The dust removal assembly 8 is used to filter dust in the air. By setting the dust removal assembly 8, the dust in the air is filtered, thereby effectively avoiding the situation where dust in the air enters the drying box 2 and is mixed with the chitosan oligosaccharide powder when the hot air blower 42 is working to transport hot air into the drying box 2; the dust removal assembly 8 includes a fixed shell 81 that is movably sleeved on the end of the air inlet pipe 7 and threadedly connected to the air inlet pipe 7, the fixed shell 81 is provided with an air inlet hole 811 connected to the air inlet pipe 7, and a filter plate 82 for blocking the air inlet hole 811 is inserted in the fixed shell 81. When the fixed shell When 81 is threadedly connected to the air inlet pipe 7, the second filter plate 82 can form a conflict with the inner wall of the air inlet pipe 7 and the fixed shell 81. Both the filter plate 1 54 and the filter plate 2 82 adopt high-efficiency filters. When in use, when the hot air blower 42 works to transport hot air into the drying box 2, the external air flows along the air inlet pipe 7 to the air inlet end of the hot air blower 42. During this period, the air enters the air inlet pipe 7 through the air inlet hole 811. When the air passes through the air inlet hole 811, it contacts the second filter plate 82, and the dust in the air can be filtered through the second filter plate 82. When the filter plate 2 82 needs to be replaced, it can be disassembled by rotating the fixed shell 81, so that the filter plate 2 82 in the fixed shell 81 can be disassembled and replaced, and the operation is simple.
