Description

Technical Field

[0001] This invention relates to the field of white kidney bean extraction technology, specifically to a white kidney bean starch inhibitor extraction device. Background Technology

[0002] Weigh and dry white kidney beans, pulverize them through an 80-mesh sieve, and mix them with deionized water at a ratio of 1:8. Place the mixture in an ultrasonic processor and maintain the ultrasonic power for a certain time. Then, centrifuge at 4℃ and 5000 rpm for 15 minutes, collecting the supernatant, which is the crude extract of white kidney bean α-amylase inhibitor. Purify the inhibitor using an organic membrane separator. Filter the crude extract through a microfiltration membrane, then use an ultrafiltration membrane with a molecular weight cutoff of 50 kDa. Filter the filtrate again through an ultrafiltration membrane with a molecular weight cutoff of 20 kDa. Collect the retentate and concentrate it by rotary evaporation at 50℃ to obtain the concentrated starch inhibitor solution. Dilute the concentrate with deionized water. A certain concentration of porous starch is added and stirred to disperse it as a core material. Resistant dextrin is prepared with deionized water to a certain concentration, stirred to dissolve it, and then added to the core material. The mixture is then encapsulated at a set temperature for a certain time. Microencapsulated white kidney bean α-starch inhibitor is prepared by spray drying. During the preparation process, different materials need to be added for auxiliary extraction. Since the amount of each different raw material will affect the final concentration of starch inhibitor, the comparison factor is often poor during extraction. The control of the required concentration or suitable concentration of starch inhibitor is often low. Therefore, a white kidney bean starch inhibitor extraction device is needed. Summary of the Invention

Deionized water is introduced into the layered extraction chambers in different amounts through one of the addition tubes, and porous starch is introduced into the layered extraction chambers in different amounts through the other addition tubes. The concentration of the desired starch inhibitor in the layered extraction chambers is compared.

[0006] As a further aspect of the present invention: the microencapsulation box is sealed with an inlet pipe for replenishing the concentrate, and the microencapsulation box is sealed with an outlet pipe for discharging the microencapsulated inhibitor; by discharging the starch inhibitor concentrate into the stratified extraction chamber through the inlet pipe, a flow meter can be installed on the inlet pipe to control the flow rate of the concentrate into different stratified extraction chambers, so that different stratified extraction chambers can store different amounts of concentrate, which is convenient for subsequent proportioning. After being encapsulated at a set temperature for a certain period of time, the concentrate is discharged through the outlet pipe and spray-dried to prepare the white kidney bean starch inhibitor.

[0007] As a further embodiment of the present invention: several microcapsule embedding boxes are fixedly connected to each other, and the stirring central shaft is driven to rotate by a driving component, one end of which extends into the bottommost microcapsule embedding box; the driving component is a motor, which controls the rotation of the stirring central shaft. When the stirring central shaft can drive the stirring blades to rotate, it stirs the raw materials inside the layered extraction chamber, thereby dispersing the raw materials.

[0008] As a further aspect of the present invention: a plurality of stirring blades are fixedly connected to the outer side of the stirring center shaft, and the plurality of stirring blades are respectively located in a plurality of the layered extraction chambers. The length of the stirring blades is less than the diameter of the layered extraction chamber.

The manifold plate contains two storage boxes for storing deionized water and porous starch, respectively. One end of each of the two addition pipes is sealed to one of the two storage boxes. The required raw materials are stored in the storage boxes. Deionized water can be pumped into the stirring center shaft through the addition pipes, and then discharged through the discharge port of the discharge plate. A one-way valve and a flow meter can be installed at the discharge port to control the required flow rate, thereby allowing the required amount of deionized water to enter the stratified extraction chamber. The deionized water is diluted to the desired concentration, and a certain amount of porous starch is added, stirred, and dispersed to serve as the core material. The porous starch can flow through the addition pipes and be discharged through the discharge port of the discharge plate. A one-way valve and a flow meter can be installed at the discharge port to control the required flow rate, thereby allowing the required amount of porous starch to enter the stratified extraction chamber.

[0011] As a further embodiment of the present invention: one end of the addition tube extends into the interior of the stirring center shaft, and one end of the addition tube is opposite to the discharge plate; the material is cleared by the addition tube and discharged through the discharge plate to the end point, entering the stratified extraction chamber.

After preparation, an operable pusher rod is provided on the outside of the pusher plate through the inner hole communicating with the layered extraction chamber, which can push the pusher plate to move. Furthermore, the bottom surface inside the preparation delivery box has two concave surfaces facing the center to facilitate liquid flow.

[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] Example 1:

[0025] Please see Figures 1-3In this embodiment of the invention, a white kidney bean starch inhibitor extraction device includes several microencapsulation boxes 1, which are stacked from bottom to top. Each microencapsulation box 1 has a layered extraction chamber 101 for placing concentrated liquid inside. A liquid flow control component 2 is provided on the outside of the microencapsulation box 1. The liquid flow control component 2 includes a stirring center shaft 21, two addition tubes 23, and several discharge trays 24. Deionized water is introduced into the layered extraction chambers 101 in different amounts through one of the addition tubes 23, and porous starch is introduced into the layered extraction chambers 101 in different amounts through the other addition tube 23. The concentration of the desired starch inhibitor in the layered extraction chambers 101 is compared.

[0026] In this implementation scheme: White kidney bean starch inhibitor is extracted by analyzing the crude extract of white kidney bean α-amylase inhibitor. The starch inhibitor concentrate is discharged into the layered extraction chamber 101 through the inlet pipe 11. A flow meter can be installed on the inlet pipe 11 to control the flow rate of the concentrate into different layered extraction chambers 101, allowing each chamber to store different amounts of concentrate for subsequent proportioning. Deionized water needs to be added to the concentrate. Deionized water and porous starch are added in different proportions to the layered extraction chambers 101 through the addition pipe 23, and after stirring and dispersion, they serve as the core material. A distribution plate 22 is fixedly connected to the outer wall of the stirring center shaft 21. The distribution plate 22 has two storage boxes for storing deionized water and porous starch respectively. One end of each of the two addition pipes 23 is sealed to one of the two storage boxes. The required raw materials are stored in a storage box. Deionized water is pumped into the stirring shaft 21 through the addition pipe 23, and then discharged through the discharge hole 241 of the discharge plate 24. A one-way valve and a flow meter can be installed on the discharge hole 241 to control the required flow rate, thereby allowing the required amount of deionized water to enter the layered extraction chamber 101. The deionized water is diluted to the desired concentration, and a certain amount of porous starch is added and stirred to disperse it as a core material. The porous starch flows through the addition pipe 23 and is discharged through the discharge hole 241 of the discharge plate 24. A one-way valve and a flow meter can be installed on the discharge hole 241 to control the required flow rate, thereby allowing the required amount of porous starch to enter the layered extraction chamber 101. Several microencapsulation boxes 1 are fixedly connected to each other. The stirring shaft 21 is driven to rotate by a drive unit. One end of the stirring shaft 21 extends into the bottommost microencapsulation box 1. The drive unit is a motor, which controls the rotation of the stirring shaft 21. When the stirring center shaft 21 can drive the stirring blade 25 to rotate, it can stir the raw materials inside the layered extraction chamber 101, thereby dispersing the raw materials.

[0027] Subsequently, resistant dextrin is added. A certain amount of resistant dextrin can be selected inside the preparation feeding box 31, and deionized water is added to prepare a certain concentration. The microencapsulation box 1 is provided with a preparation component 3 on the outside. The preparation component 3 includes a preparation feeding box 31 and a push plate 32. The preparation feeding box 31 is fixed on the outside of the microencapsulation box 1, and the push plate 32 is slidably connected inside the preparation feeding box 31. The preparation feeding box 31 has an inner hole that communicates with the layered extraction chamber 101. The core material is slowly added by pressing the push plate 32. After being embedded for a certain time at a set temperature, it is discharged through the liquid outlet pipe 12 and spray-dried to prepare white kidney bean starch inhibitor. During the addition process, since each microcapsule embedding box 1 is equipped with a preparation delivery box 31, the preparation delivery box 31 can be used to prepare resistant dextrin. Under the action of different preparation delivery boxes 31, different ratios of resistant dextrin can be placed in different layered extraction chambers 101, thereby achieving the required concentration or appropriate numerical concentration for preparation. Once the formulation is complete, the inner hole connected to the layered extraction chamber 101 allows for the operation of an operable pusher rod on the outside of the pusher plate 32, which can move the pusher plate 32. The bottom surface inside the formulation feeding box 31 has two concave surfaces facing inwards towards the center, facilitating liquid flow. Operating on the pusher rod, the pusher plate 32 can move to the center position, thereby squeezing the resistant dextrin into the through-hole. A one-way valve is installed in the through-hole, allowing the required amount of resistant dextrin, prepared with deionized water at the desired concentration, to be added to the core material. After encapsulation at a set temperature for a certain time, the microencapsulated inhibitor is prepared by spray drying. By controlling the spray drying conditions, the required concentration of starch inhibitor or a suitable concentration of starch inhibitor can be obtained.

[0028] In the preparation process, porous starch is used as an adsorbent and resistant dextrin as a wall material to microencapsulate the inhibitor extracted from white kidney beans, thereby improving the stability of its amylase inhibitory activity after treatment with high temperature, different pH values, and artificial gastric juice. The raw materials inside different layered extraction chambers 101 are controlled, and comparisons can be made during extraction, so as to extract the required concentration of starch inhibitor or a suitable concentration of starch inhibitor.

[0029] like Figures 1-3 As shown, the present invention also provides a method for using the white kidney bean starch inhibitor extraction device, the specific steps of which are as follows:

[0030] A: By discharging the starch inhibitor concentrate into the layered extraction chamber 101 through the inlet pipe 11, and surrounding it with preparation tools for adding auxiliary materials, deionized water and porous starch in different amounts are respectively placed in the layered extraction chamber 101 through two addition pipes 23, and after stirring and dispersing, they are used as core materials.

[0031] B: A certain amount of resistant dextrin can be selected inside the preparation feeding box 31 and deionized water can be added to prepare a certain concentration. It is then slowly added to the core material by pressing the push plate 32. After being embedded for a certain period of time at a set temperature, it is discharged through the liquid outlet pipe 12 and spray-dried to prepare white kidney bean starch inhibitor.

[0032] The working principle of this invention is as follows: A crude extract of white kidney bean α-amylase inhibitor is obtained by extracting white kidney bean α-amylase inhibitor. The concentrated starch inhibitor is discharged into the layered extraction chamber 101 through the inlet pipe 11. A flow meter can be installed on the inlet pipe 11 to control the flow rate of the concentrated liquid into different layered extraction chambers 101, allowing each chamber to store different amounts of concentrated liquid for subsequent proportioning. Deionized water is added to the concentrated liquid. Deionized water and porous starch are added in different proportions to the layered extraction chambers 101 through the addition pipe 23, and dispersed by stirring to form the core material. The required raw materials are stored in a storage box. Deionized water can be pumped through the addition pipe 23 into the stirring center shaft 21, and then discharged through the discharge hole 241 of the discharge plate 24. A one-way valve and a flow meter can be installed on the discharge port 241 to control the required flow rate, thereby allowing the required amount of deionized water to enter the stratified extraction chamber 101. The deionized water is diluted to the desired concentration, and a certain amount of porous starch is added, stirred, and dispersed to serve as the core material. The porous starch can flow through the addition pipe 23 and be discharged from the discharge port 241 of the discharge plate 24. A one-way valve and a flow meter can be installed on the discharge port 241 to control the required flow rate, thereby allowing the required amount of porous starch to enter the stratified extraction chamber 101. The driving component is a motor, which controls the rotation of the stirring center shaft 21. When the stirring center shaft 21 drives the stirring blades 25 to rotate, it stirs the raw materials inside the stratified extraction chamber 101, thereby dispersing the raw materials. Subsequently, resistant dextrin is added. A certain amount of resistant dextrin can be selected inside the preparation delivery box 31, and deionized water is added to prepare a certain concentration. The microencapsulation box 1 is equipped with a preparation component 3 on its outside. By pressing the push plate 32, the resistant dextrin is slowly added to the core material. After being embedded for a certain period of time at a set temperature, it is discharged through the liquid outlet pipe 12 and spray-dried to prepare white kidney bean starch inhibitor. During the addition process, since the preparation delivery box 31 is set on the outside of the microencapsulation box 1, the resistant dextrin can be prepared inside the preparation delivery box 31. Under the action of different preparation delivery boxes 31, different ratios of resistant dextrin can be placed in different layered extraction chambers 101, thereby achieving the required concentration or a suitable numerical concentration.Once the formulation is complete, the inner hole connected to the layered extraction chamber 101 allows for the operation of an operable pusher rod on the outside of the pusher plate 32, which can move the pusher plate 32. The bottom surface inside the formulation feeding box 31 has two concave surfaces facing inwards towards the center, facilitating liquid flow. Operating on the pusher rod, the pusher plate 32 can move to the center position, thereby squeezing the resistant dextrin into the through-hole. A one-way valve is installed in the through-hole, allowing the required amount of resistant dextrin, prepared with deionized water at the desired concentration, to be added to the core material. After encapsulation at a set temperature for a certain time, the microencapsulated inhibitor is prepared by spray drying. By controlling the spray drying conditions, the required concentration of starch inhibitor or a suitable concentration of starch inhibitor can be obtained.

[0033] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
