Description

Technical Field

[0001] The invention relates to the technical field of functional foods, and in particular to a dietary fiber powder composition for promoting intestinal peristalsis and a preparation method thereof. Background Art

[0002] Dietary fiber powder has the effects of promoting digestion and assisting weight loss. There are different types of dietary fiber powders in the prior art, but the prior art lacks a dietary fiber powder that can reduce the body's absorption of cholesterol and play a lipid-lowering effect.

[0003] In addition, when preparing fiber powder in the prior art, it is generally necessary to use a processing tank to crush the powder raw materials into small particles that are easy to eat. However, the processing tanks in the prior art still have certain deficiencies when crushing the raw materials. When crushing the powder raw materials, the processing tanks in the prior art may not crush them thoroughly, and the prepared powder may contain larger particles of powder, which may affect the taste. Summary of the invention

[0004] The purpose of the present invention is to solve the problems raised in the background technology, and to propose a dietary fiber powder composition for promoting intestinal peristalsis and a preparation method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A dietary fiber powder composition for promoting intestinal peristalsis comprises the following components by weight: 3-5 parts of psyllium husk powder, 2.8-3.5 parts of resistant dextrin, 1.5-3 parts of polydextrose, 0.8-1.4 parts of passion fruit powder, 0.8-1.6 parts of oat fiber powder, 0.7-1.4 parts of auxiliary agent, 0.1-0.5 parts of white kidney bean extract, 0.1-0.5 parts of pea fiber, 0.1-0.5 parts of chia seeds, 0.1-0.2 parts of citric acid and 0.003-0.005 parts of turmeric.

[0007] Preferably, the auxiliary agent is a sweetener.

[0008] Furthermore, the sweetener comprises erythritol and galactomannan, and the mass ratio of the erythritol to the galactomannan is 4:3.

[0009] A method for preparing a dietary fiber powder composition for promoting intestinal peristalsis comprises the following steps:

[0010] Step S1, pouring the psyllium husk into a processing tank for crushing;

[0011] Step S2, taking out the crushed round bag of psyllium husk powder and adding it into a mixing tank;

[0012] Step S3, taking resistant dextrin, polydextrose, passion fruit powder, oat fiber powder, white kidney bean extract, pea fiber, citric acid, and turmeric, respectively, through a 30-50 mesh sieve and putting them into a mixing tank with chia seeds;

[0013] Step S4, mixing and stirring thoroughly;

[0014] Step S5: adding erythritol and galactomannan that have passed through a 30-50 mesh sieve into a mixing tank, and mixing them thoroughly to obtain a dietary fiber powder composition.

[0015] Furthermore, the crushing process in step S1 is as follows:

[0016] S101, opening a first can cover on the processing tank, and pouring the psyllium husk to be crushed into the processing tank;

[0017] S102, closing the first tank cover and starting the driving motor, which drives the crushing roller to rotate the crushing shell;

[0018] S103, after crushing, small-particle shell powder passes through the first screen and falls into the collection box, and large-particle shell powder falls into the air duct through the inclined hole, and air is blown into the air duct by the jet pump, and the large-particle shell powder is blown into the top of the processing tank and crushed again;

[0019] S104, the crushed material is screened by the first screen, and the large-particle shell powder is blown to the top of the processing tank again;

[0020] S105, taking out the shell powder that falls into the collection box after multiple crushings for later use.

[0021] Furthermore, the crushing operation in step S102 is specifically as follows:

[0022] The shell poured into the processing tank falls onto the top of the crushing roller through the guide plate, the driving motor drives the driving rod to rotate, the driving rod drives the crushing roller to rotate, and the two groups of crushing rollers engage and rotate to crush the shell.

[0023] Furthermore, the operation of the screening cycle crushing in step S103 is as follows:

[0024] The crushed shell powder is sieved through the first sieve, and large particles of shell powder fall onto the electrical box through the inclined hole. After sieving for a period of time, the jet pump is started, and the jet pump sprays air into the air duct. The rapidly ejected gas pushes the electrical box to move up quickly. The first limit ring set in the air duct will resist the rapidly moving electrical box. At this time, the large particles of shell powder on the electrical box will be blown to the top of the processing tank and fall on the guide plate again. After being guided by the guide plate, it is crushed again. At the same time, after the electrical box moves up quickly, the pull rope on the electrical box is loosened. At this time, the counterweight block drives the pressure plate to slide down quickly, and the pressure plate quickly cuts down the large particles of powder blocking the inclined hole.

[0025] Furthermore, the first screen is a V-shaped screen.

[0026] Furthermore, a limit rod is fixedly connected to the side wall of the collection box, and the counterweight block is slidably connected to the limit rod.

[0027] Furthermore, a limiting plate is fixedly connected to the limiting rod, and the limiting plate and the counterweight block abut against each other.

[0028] Compared with the prior art, the present invention provides a dietary fiber powder composition for promoting intestinal peristalsis and a preparation method thereof, which has the following beneficial effects:

[0029] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art. The psyllium husk powder and polydextrose in the dietary fiber powder composition can reduce the absorption of cholesterol by the human body, thereby achieving the effect of lowering blood lipids. Meanwhile, the resistant dextrin in the composition can increase satiety, thereby being beneficial for weight loss. The dietary fiber composition has high dietary fiber, is beneficial for promoting intestinal peristalsis, and has a sweet and sour taste. The present invention crushes the psyllium husk in the preparation raw material, thereby fully crushing the psyllium husk into psyllium husk powder with finer particles, thereby ensuring the delicate taste of the subsequent preparation of the dietary fiber powder composition.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] Example:

[0043] A dietary fiber powder composition for promoting intestinal peristalsis comprises the following components by weight: 3-5 parts of psyllium husk powder, 2.8-3.5 parts of resistant dextrin, 1.5-3 parts of polydextrose, 0.8-1.4 parts of passion fruit powder, 0.8-1.6 parts of oat fiber powder, 0.7-1.4 parts of auxiliary agent, 0.1-0.5 parts of white kidney bean extract, 0.1-0.5 parts of pea fiber, 0.1-0.5 parts of chia seeds, 0.1-0.2 parts of citric acid and 0.003-0.005 parts of turmeric.

[0044] The auxiliary agent is a sweetener.

[0045] The sweetener comprises erythritol and galactomannan, and the mass ratio of the erythritol to the galactomannan is 4:3.

[0046] A method for preparing a dietary fiber powder composition for promoting intestinal peristalsis comprises the following steps:

[0047] Step S1, pouring the psyllium husk into a processing tank 1 for crushing;

[0048] Step S2, taking out the crushed round bag of psyllium husk powder and adding it into a mixing tank;

[0049] Step S3, taking resistant dextrin, polydextrose, passion fruit powder, oat fiber powder, white kidney bean extract, pea fiber, citric acid, and turmeric, respectively, passing through a 40-mesh sieve and putting them into a mixing tank with chia seeds;

[0050] Step S4, mixing and stirring thoroughly;

[0051] Step S5: adding erythritol and galactomannan that have passed through a 40-mesh sieve into a mixing tank, and mixing them thoroughly to obtain a dietary fiber powder composition.

[0052] A material guide plate 101 is fixedly connected in the processing tank 1, and an air duct 4 is fixedly connected to the material guide plate 101. The two groups of air ducts 4 are symmetrically arranged, and a collecting box 6 is fixedly connected to the side wall of the air duct 4. A driving rod 501 is rotatably connected to the processing tank 1, and a crushing roller 5011 is fixedly connected to the driving rod 501. The collecting box 6 is located directly below the crushing roller 5011. A first screen 602 is fixedly connected to the collecting box 6. Inclined holes 603 are provided on the air duct 4 and the collecting box 6, and the bottom end of the first screen 602 is flush with the bottom end of the inclined hole 603.

[0053] Reference Figure 3 , Figure 6-Figure 7 During use, the shell to be processed is poured into the processing tank 1, and the driving motor 5 is started. The driving motor 5 will drive the driving rod 501 fixedly connected to its driving end to rotate, and the driving rod 501 will drive the crushing roller 5011 to engage and rotate. At this time, the crushing roller 5011 can effectively crush the shell.

[0054] An electrical box 403 is slidably connected in the air duct 4, and tourmaline is placed in the electrical box 403. A limiting rod 604 is fixedly connected to the inner wall of the collecting box 6, and a counterweight block 7 is slidably connected to the limiting rod 604. A pull rope 8 is fixedly connected to the counterweight block 7. The end of the pull rope 8 away from the counterweight block 7 is fixedly connected to the electrical box 403, and a pressure plate 701 is fixedly connected to the bottom of the counterweight block 7.

[0055] Reference Figure 3 , Figure 4 When the jet pump 3 sprays high-temperature dry gas into the air duct 4, the sprayed gas will first pass through the electrical box 403. At this time, when the gas passes through the tourmaline stone in the electrical box 403, it will carry the negative charge generated by the tourmaline stone. Finally, when the gas blown out of the air duct 4 blows on the guide plate 101, the gas with negative charge can effectively blow off the shell powder adhered to the guide plate 101 due to static electricity, further improving the crushing efficiency and crushing effect.

[0056] It should be noted that the weight of the electrical box 403 and the tourmaline in the box is greater than the weight of the counterweight 7, and when the jet pump 3 sprays air into the air duct 4, the jet thrust is greater than the gravity of the electrical box 403 and the tourmaline in the box to ensure that the electrical box can be pushed quickly.

[0057] Reference Figure 3-Figure 5 The crushed shell will fall into the first sieve 602 in the collecting box 6. The first sieve 602 can screen out qualified small-particle shell powder and illegal large-particle shell powder. The large-particle shell powder will roll into the air duct 4 along the first sieve 602, and the shell powder entering the air duct 4 will fall on the electrical box 403. After screening for a period of time, turn on the jet pump 3 to spray high-temperature dry gas into the air duct 4. The large amount of gas sprayed at high speed will first push the electrical box 403 to move upward. After the electrical box 403 moves up a distance, it will resist the first limit ring 401. At this time, the electrical box 403 will no longer move up. At this time, the injected gas will all be ejected from the air hole 4033. The ejected gas will push the large-particle material in the air duct 4 to move upward, and enter the guide plate 101 of the processing tank 1 again through the air duct 4, and be crushed again by the crushing roller 5011.

[0058] It should be noted that the gas ejected by the jet pump 3 is sufficient to push the electrical box 403 and the materials above the electrical box 403 , and the gas blown out through the air hole 4033 is sufficient to blow the shell powder floating in the air duct 4 out of the air duct 4 .

[0059] A jet pump 2 and a jet pump 3 are fixedly connected to the side wall of the processing tank 1, a feed pipe 202 is fixedly connected to the jet pump 2, and the feed pipe 202 is connected to an external liquid nitrogen storage tank, an air intake pipe 302 is fixedly connected to the jet pump 3, and the air intake pipe 302 is connected to an external high-temperature dry gas storage tank, a jet pipe 201 is fixedly connected to the driving end of the jet pump 2, an end of the jet pipe 201 away from the jet pump 2 is fixedly connected to the air duct 4, and the jet end of the jet pipe 201 is placed in the air duct 4, a jet pipe 301 is fixedly connected to the air outlet end of the jet pump 3, and an end of the jet pipe 301 away from the jet pump 3 is connected to the air duct 4.

[0060] Reference Figure 3-Figure 7 When the jet pump 3 is jetting, the spray pump 2 is turned on. The spray pump 2 will spray the extracted liquid nitrogen into the air duct 4 through the injection pipe 201. The liquid nitrogen sprayed into the air duct 4 will come into contact with the shell powder carried by the high-temperature dry gas. At this time, the liquid nitrogen and the shell powder are instantly contacted and cooled, thereby embrittled the shell powder. When the embrittled shell powder is crushed again, it can be more conducive to the crushing of large-particle shell powder.

[0061] It should be noted that the driving force of the gas injected by the jet pump 3 is much greater than the gravity of the large particle material, so as to ensure that the large particle material can be effectively blown into the top of the processing tank 1.

[0062] A first limiting ring 401 and a second limiting ring 402 are fixedly connected to the air duct 4 , and the second limiting ring 402 is located directly below the first limiting ring 401 .

[0063] Reference Figure 4 , Figure 8 A conical plate 4031 is fixedly connected to the electrical box 403 , and an air hole 4033 is opened on the electrical box 403 .

[0064] Through the conical plate 4031 disposed in the electrical box 403 , the material leaking out of the inclined hole 603 can effectively slide to the top of the air hole 4033 .

[0065] It should be noted that after the shell powder falls on the top of the air hole 4033, when the air duct 4 transports the gas, the air blown out of the air hole 4033 is blocked by the shell powder and the obstruction is negligible.

[0066] It should also be noted that the jet pump 3 performs intermittent jetting.

[0067] A second screen 4032 is fixedly connected to the electrical box 403 , and the second screen 4032 can prevent shell powder from falling into the electrical box 403 .

[0068] A discharge pipe 601 is fixedly connected to the bottom of the collecting box 6 , and a valve is provided on the discharge pipe 601 .

[0069] After the crushing process is completed, the second can cover 103 is manually opened, and the valve on the discharge pipe 601 is opened to discharge the processed shell powder.

[0070] It should be noted that the valve on the discharge pipe 601 can be a solenoid valve available on the market.

[0071] The crushing process steps in step S1 are as follows:

[0072] S101, opening the first tank cover 102 on the processing tank 1, and pouring the psyllium husk to be crushed into the processing tank 1;

[0073] S102, closing the first tank cover 102, and starting the driving motor 5, which drives the crushing roller 5011 to rotate the crushing shell;

[0074] S103, after crushing, the small-particle shell powder passes through the first screen 602 and falls into the collecting box 6, and the large-particle shell powder passes through the inclined hole 603 and falls into the air duct 4. The air is blown into the air duct 4 by the jet pump 3, and the large-particle shell powder is blown into the top of the processing tank 1 and crushed again;

[0075] S104, the crushed material is screened by the first screen 602, and the large-particle shell powder is blown to the top of the processing tank 1 again;

[0076] S105, the shell powder dropped into the collection box 6 after multiple crushing is taken out for later use.

[0077] The crushing operation in step S102 is specifically as follows:

[0078] The shell poured into the processing tank 1 falls through the guide plate 101 onto the top of the crushing roller 5011, the driving motor 5 drives the driving rod 501 to rotate, the driving rod 501 drives the crushing roller 5011 to rotate, and the two sets of crushing rollers 5011 engage and rotate to crush the shell.

[0079] The operation of the screening cycle crushing in step S103 is as follows:

[0080] The crushed shell powder is sieved through the first sieve 602, and the large particles of shell powder fall onto the electrical box 403 through the inclined hole 603. After sieving for a period of time, the jet pump 3 is started, and the jet pump 3 sprays air into the air duct 4. The rapidly ejected gas pushes the electrical box 403 to move upward rapidly. The first limit ring 401 provided in the air duct 4 will resist the rapidly moving upward electrical box 403. At this time, the large particles of shell powder on the electrical box 403 will be blown to the top of the processing tank 1 and fall onto the guide plate 101 again. After being guided by the guide plate 101, it is crushed again. At the same time, after the electrical box 403 moves upward rapidly, the pull rope 8 on the electrical box 403 is loosened. At this time, the counterweight block 7 drives the pressure plate 701 to slide down rapidly, and the pressure plate 701 quickly cuts down the large particles of powder blocking the inclined hole 603.

[0081] Reference Figure 3 , the first screen 602 is a V-shaped screen.

[0082] By setting the first screen 602 as a V-shaped screen, large-particle shell powder can be effectively made to roll down quickly.

[0083] It should be noted that the mesh sizes of the first sieve 602 and the second sieve 4032 can be adjusted according to production needs.

[0084] Reference Fig. 9 The limiting rod 604 is fixedly connected with a limiting plate 6041, and the limiting plate 6041 and the counterweight block 7 are against each other.

[0085] By setting the limiting plate 6041, when the pull rope 8 pulls the counterweight block 7 to reset, it can effectively block the counterweight block 7, and effectively prevent the counterweight block 7 from excessively sliding and detaching from the limiting rod 604.

[0086] Reference Figure 3-Figure 5 ,、 Figure 8-Figure 9 When the electrical box 403 moves up quickly, the pull rope 8 will be loosened, and the counterweight block 7 will slide down quickly. The rapid decline of the counterweight block 7 will drive the pressing plate 701 to move down, and the conical surface of the pressing plate 701 will cut and block the larger particles of shell powder at the position of the inclined hole 603 to ensure that the cut shell powder can roll out through the inclined hole 603.

[0087] The psyllium husk powder and polydextrose in the dietary fiber powder composition can reduce the absorption of cholesterol by the human body, thereby achieving the effect of lowering blood lipids. Meanwhile, the resistant dextrin in the composition can increase satiety, thereby being beneficial for weight loss. The dietary fiber composition has high dietary fiber, is beneficial for promoting intestinal peristalsis, and has a sweet and sour taste. The present invention adopts a processing tank 1 to crush the psyllium husk in the preparation raw material, thereby fully crushing the psyllium husk into psyllium husk powder with finer particles, thereby ensuring the delicate taste of the subsequent preparation of the dietary fiber powder composition.

[0088] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
