Description

Technical Field

[0001] The utility model relates to the technical field of enzymatic hydrolysis processing equipment, in particular to an enzymatic hydrolysis device for preparing chitosan oligosaccharides. Background Art

[0002] Chitosan oligosaccharide, also known as chitosan oligosaccharide or low-molecular-weight chitosan, has many unique functions that chitosan does not have, such as higher solubility, complete solubility in water, and easy absorption and utilization by organisms. Its function is fourteen times that of chitosan. Chitosan oligosaccharide is the only positively charged cationic alkaline amino oligosaccharide in nature and is animal cellulose.

[0003] The patent announcement number is CN212504913U, which discloses an enzymatic hydrolysis device for preparing chitosan oligosaccharides in the field of enzymatic hydrolysis processing equipment, including a kettle body and multiple supporting legs. The top of the kettle body is fixedly connected to a fixed plate, and a reduction motor is fixedly provided in the middle of the top of the fixed plate. The output end of the reduction motor is fixedly connected to a stirring rod, and the bottom end of the stirring rod is fixedly connected to a stirring blade. The bottom of the stirring rod is fixedly provided with a screw shaft, and the external rotation of the screw shaft is connected to a turbine dispersion disk. The top and bottom ends of the outer wall of the turbine dispersion disk are respectively fixedly connected to a plurality of first support plates and a plurality of second support plates.

[0004] The enzymatic hydrolysis device in the above patent still has certain deficiencies. Due to the enzymatic hydrolysis: it is the movement of the body through the digestive tract and the enzymatic hydrolysis of the digestive gland secretions, which makes large pieces of food with complex molecular structures, but the interaction between the two cannot be ignored. Chitosan oligosaccharides need to be processed by enzymatic hydrolysis. An enzymatic hydrolysis device is required during the stirring process. However, in the existing enzymatic hydrolysis device, since the traditional mixing tank powder is added manually and directly poured into the mixing tank, it is easy to cause the powder to form lumps when the powder is mixed with water, which is not conducive to the subsequent continuous stirring and enzymatic hydrolysis, and there is a phenomenon of incomplete enzymatic hydrolysis. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide an enzymatic hydrolysis device for preparing chitosan oligosaccharides, which can avoid the formation of lumps by mixing powder and water during the enzymatic hydrolysis process and improve the enzymatic hydrolysis efficiency.

DETAILED DESCRIPTION

[0024] like Figure 1-5 As shown: An enzymatic hydrolysis device for preparing chitosan oligosaccharides, including an enzymatic hydrolysis reaction tank 1, a blanking component 6 is arranged above the enzymatic hydrolysis reaction tank 1, and the blanking component 6 includes a driving bin 4 and a blanking bin 5. A driving motor 3 is fixedly installed above the driving bin 4, and the driving shaft of the driving motor 3 is fixedly connected to a transmission rod 31. The other end of the transmission rod 31 passes through the driving bin 4 and the enzymatic hydrolysis reaction tank 1 in sequence and enters the enzymatic hydrolysis reaction tank 1. A plurality of stirring rods 32 are evenly arranged on the transmission rod 31, and a transmission component is arranged in the driving bin 4. The blanking bin 5 includes a blanking port 50 opened at the top of the enzymatic hydrolysis reaction tank 1, and the blanking bin 5 is connected to the enzymatic hydrolysis reaction tank 1 through the blanking port 50. The two inner side walls of the blanking bin 5 are symmetrically provided with limiting grooves 57, and the blanking net components are slidably connected in the two limiting grooves 57.

[0025] The bottom of the enzymatic hydrolysis reaction tank 1 is provided with supporting legs 2 , and the bottom of the enzymatic hydrolysis reaction tank 1 is also provided with a discharge pipe 8 , and a valve 9 is provided on the discharge pipe 8 .

[0026] The transmission assembly includes a first transmission column 43 located adjacent to the transmission rod 31 in the drive bin 4, a second gear disc 42 is fixedly sleeved on the first transmission column 43 near the middle position, a first bevel gear 44 is fixedly installed on the top of the first transmission column 43, a first gear disc 41 is fixedly sleeved on the transmission rod 31 in the drive bin 4, and the first gear disc 41 is meshed with the second gear disc 42.

[0027] The blanking net assembly includes a blanking and dispersing net 55 , and two limiting blocks 58 are symmetrically provided at both ends of the blanking and dispersing net 55 . The limiting blocks 58 are slidably inserted into the limiting grooves 57 .

[0028] A second transmission column 51 is horizontally arranged below the discharge dispersion net 55. The fixed end of the second transmission column 51 is transmission-connected to the side wall of the discharge bin 5. The driving end of the second transmission column 51 passes through the other side wall of the discharge bin 5 and enters the driving bin 4. A second bevel gear 52 is fixedly mounted on the driving end of the second transmission column 51, and the second bevel gear 52 is meshed with the first bevel gear 44.

[0029] When the driving motor 3 is working, it drives the transmission rod 31 to rotate. At this time, the first gear plate 41 rotates along with the transmission rod 31. The first gear plate 41 drives the second gear plate 42 to rotate, so that the first transmission column 43 rotates. When the first transmission column 43 rotates, the second transmission column 51 rotates through the cooperation of the first bevel gear 44 and the second bevel gear 52.

[0030] Two interference turntables 53 are symmetrically fixedly mounted on the second transmission column 51 , and each interference turntable 53 is provided with three interference balls 54 arranged at intervals.

[0031] A resisting spring 56 is fixedly mounted on the bottom of the two limiting grooves 57 , and the other end of the resisting spring 56 is in contact with the bottom surface of the material dispersing net 55 .

[0032] A material dumping bin 59 is provided above the material dispersing net 55 , and a material guide plate is provided obliquely in the material dumping bin 59 .

[0033] A feed pipe 7 is also provided on the top of the enzymatic hydrolysis reaction tank 1 .

[0034] During operation, the chitosan oligosaccharide raw material and water enter the enzymolysis reaction tank 1 through the feed pipe 7, and the enzymolysis powder enters the discharge bin 5 through the pouring bin 59 and is scattered on the discharge dispersion net 55. Under the action of gravity, the discharge dispersion net 55 compresses the resistance spring 56, so that the discharge dispersion net 55 is in contact with the resistance ball 54. At this time, the driving motor 3 works, driving the stirring rod 32 on the transmission rod 31 to stir the chitosan oligosaccharide raw material in the enzymolysis reaction tank 1. While the transmission rod 31 is working, it drives the first transmission column 43 to rotate through the first gear disc 41, and then drives the second transmission column 51 to rotate through the cooperation of the first bevel gear 44 and the second bevel gear 52 on the first transmission column 43. At this time, the second transmission column 51 drives the resistance turntable 53 to rotate, and the resistance ball 54 rotates following the resistance turntable 53.

[0035] With this design, when the resistance ball 54 moves away from the dispersing net 55, the dispersing net 55 continues to descend in the limiting groove 57 as gravity compresses the resistance spring 56. Then, when the resistance ball 54 contacts the dispersing net 55 again, it lifts up the dispersing net 55, causing the dispersing net 55 to vibrate up and down in the limiting groove 57 under the action of the resistance ball 54, thereby evenly dispersing the enzymatic powder on the dispersing net 55 and allowing it to enter the enzymatic reaction tank 1 for reaction according to the vibration frequency.

[0036] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of this utility model.
