Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a modified starch production reaction vessel. Background Technology

[0002] Starch is mainly derived from various plants such as corn, wheat, sweet potatoes, and peas. It can be classified into corn starch, sweet potato starch, pea starch, etc., depending on its source. Starch is widely used in the food industry and also plays a good role in industries such as papermaking and textiles.

[0003] With the development of science and technology, ordinary starch can no longer meet the technical requirements in different fields, so it is necessary to modify starch. Modified starch can improve the consistency and taste in the food industry, and can also be applied in other fields such as medicine and packaging, making its application range wider.

[0004] The utility model disclosed in CN214346417U is a modified starch production reactor, which includes a reaction vessel. The bottom of the reaction vessel is equipped with a discharge port, and a solenoid valve is installed on the discharge port. An n-shaped support is fixed on the top of the reaction vessel, and a motor is fixed on the top of the n-shaped support. This invention solves the technical problem of uneven mixing.

[0005] Since gelatinization is an important step in starch modification, and gelatinization also needs to be carried out at a certain temperature; however, the above-mentioned reactor cannot heat the internal materials, making it difficult to gelatinize and modify them. In addition, the internal stirring structure is simple, and it is difficult to ensure uniformity by stirring only through the stirring shaft, resulting in unsatisfactory performance. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems by providing a modified starch production reactor that can effectively stir and heat the internal starch material for gelatinization, thus meeting the modification requirements.

[0008] Preferably, the heating mechanism includes a heating coil, which is spirally disposed on the outer circumference of the reactor body, and the circumference of the reactor body is also provided with an insulating shell that covers the heating coil.

[0009] Preferably, the inner wall of the insulating shell does not contact the heating coil, and the inner wall of the insulating shell is provided with a rock wool insulation layer.

[0010] Preferably, the stirring mechanism includes a stirring shaft and an inner stirring cage and an outer stirring cage arranged around the stirring shaft. The outer diameter of the inner stirring cage is smaller than that of the outer stirring cage. Both the inner and outer stirring cages are arranged in a spring-like spiral configuration. Both the inner and outer stirring cages are coaxially arranged with the stirring shaft. When the stirring shaft rotates, it drives the inner and outer stirring cages to rotate together.

[0011] Preferably, the inner and outer mixing cages are provided with multiple reinforcing ribs along their height direction. The reinforcing ribs penetrate the corresponding inner and outer mixing cages. Multiple connecting rods are also provided around the inner and outer mixing cages, and the ends of the connecting rods are welded and fixed to the mixing shaft.

[0012] Preferably, the bottom of the stirring shaft is also provided with a welded and fixed stirring paddle, which is arc-shaped.

[0013] Preferably, the cover is also provided with a plurality of air vents arranged in an array.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please refer to Figure 1-6 A modified starch production reactor includes a reactor body 2, a cover 3 on the top of the reactor body 2, a feed inlet 32 ​​on the cover 3, a discharge outlet 4 at the bottom of the reactor body 2, wherein a ball valve is installed in the discharge outlet 4, which is normally closed, a heating mechanism is provided around the reactor body 2, a stirring mechanism 5 is provided inside the reactor body 2, and a motor 31 for driving the stirring mechanism 5 is provided in the middle of the cover 3.

[0024] In use, the mixture of water, starch and chemical agent is injected into the reactor body 2 through the inlet 32. Then, the heating mechanism and motor 31 are started. At this time, the motor 31 drives the internal stirring mechanism 5 to run and stir the internal material. At the same time, since the reactor body 2 is surrounded by a heating mechanism, the heating mechanism can raise the internal temperature of the reactor body 2, which is conducive to starch modification. Finally, the modified starch is discharged from the reactor through the outlet 4.

[0025] Specifically, the heating mechanism includes a heating coil 11, which is spirally arranged on the outer circumference of the reactor body 2. The heating coil 11 is fixed by a buckle or steel wire. The reactor body 2 is also provided with an isolation shell 1 that covers the heating coil 11. The isolation shell 1 can improve the overall safety performance and prevent external people or objects from coming into contact with the heating coil and causing burns.

[0026] In this embodiment, the heating coil 11 enables the starch material to gelatinize and be easily modified. The inner wall of the isolation shell 1 does not contact the heating coil 11. The inner wall of the isolation shell 1 is provided with a rock wool insulation layer, which can isolate the temperature and prevent the temperature of the isolation shell 1 from becoming too high. The electric heating coil 11 is connected to an external power supply and heats the internal material through the principle of heat transfer. The internal starch material gelatinizes and is modified. The gelatinization temperature is 40-80℃ and the heating (gelatinization) time is 1-2 hours.

[0027] In this embodiment, the stirring mechanism 5 includes a stirring shaft 51 and an inner stirring cage 53 and an outer stirring cage 54 disposed around the stirring shaft 51. The outer diameter of the inner stirring cage 53 is smaller than the outer diameter of the outer stirring cage 54. Both the inner stirring cage 53 and the outer stirring cage 54 are arranged in a spring-like spiral configuration. Both the inner stirring cage 53 and the outer stirring cage 54 are coaxially arranged with the stirring shaft 51. When the stirring shaft 51 rotates, it drives the inner stirring cage 53 and the outer stirring cage 54 to rotate together.

[0028] The stirring shaft 51 extends vertically upward and is coaxially connected to the output shaft of the motor. After the motor runs, the stirring shaft 51 rotates accordingly. The rotation of the stirring shaft 51 drives the inner stirring cage 53 and the outer stirring cage 54 to rotate, thereby stirring the internal materials. Since the inner stirring cage 53 and the outer stirring cage 54 are spiral-shaped and have different outer diameters, the stirring area can be greatly increased, which can make the internal materials mix quickly or stir evenly, and facilitate the gelatinization of starch by heating.

[0029] To improve the overall strength of the mixing mechanism 5, the inner mixing cage 53 and the outer mixing cage 54 are provided with a plurality of reinforcing ribs 55 along their own height direction. The reinforcing ribs 55 pass through the corresponding inner mixing cage 53 and outer mixing cage 54, and the reinforcing ribs 55 are welded and fixed to the cage at the penetration point. A plurality of connecting rods 56 are also provided around the inner mixing cage 53 and the outer mixing cage 54, and the ends of the connecting rods 56 are all welded and fixed to the mixing shaft 51.

[0030] The reinforcing rib 55 increases the mechanical strength of the two cages in the vertical direction, preventing deformation during stirring. In addition, the connecting rod 56 can stably fix the two cages to the stirring shaft 51, making them rotate together as a whole, thus meeting the usage requirements.

[0031] To further improve the stirring effect, a welding-fixed stirring paddle 52 is also provided at the bottom of the stirring shaft 51. The stirring paddle 52 is arc-shaped. The arc shape of the stirring paddle 52 is designed to fit the arc-shaped bottom surface of the reactor body to prevent the bottom material from being unable to be stirred.

[0032] As a preferred embodiment, the cover 3 is also provided with a plurality of arrayed vent holes 33. The arrangement of the vent holes allows air to circulate between the inside and outside, preventing excessive internal pressure.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
