Description

Technical Field

[0001] The invention relates to the technical field of dietary fiber preparation, in particular to dietary fiber capable of reducing oil and sugar absorption and a preparation machine thereof. Background Art

[0002] Dietary fiber is a type of carbohydrate and related substances from plant foods that cannot be digested and absorbed by the human body, but it plays an important role in maintaining human health. Simply put, dietary fiber is a "non-digestible" component in food that cannot be broken down by gastrointestinal enzymes, but it can indirectly promote the health of the digestive system through physical and chemical effects in the intestines.

[0003] For example, the patent with publication number: CN115191618B discloses a molecularly woven dietary fiber that can reduce the absorption of oil and sugar and increase the body's heat elimination. By nanofibrillation and molecular weaving of dietary fiber, a composite dietary fiber with a high barrier effect on sugars and oils in the intestine is prepared. At the same time, it can adjust intestinal microorganisms and reduce the ratio of Firmicutes / Bacteroidetes, thereby affecting the host's energy balance and increasing the body's heat elimination of feces. The molecularly woven composite dietary fiber can be widely used in health foods, functional foods, health products and special medical formula foods;

[0004] The above patent uses a spray drying device in the preparation of dietary fiber. When the existing spray drying device prepares dietary fiber, the wet material is atomized and sprayed out to mix with hot air to eliminate moisture. However, during the falling process of the powdered dietary fiber, the mixed airflow is often extracted, and an additional cyclone separator is required to separate the powdered material and the air, which increases the installation cost and makes it impossible to collect the dried powdered dietary fiber in the first place.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a dietary fiber for reducing oil and sugar absorption and a preparation machine thereof are proposed. Summary of the invention

[0008] Furthermore, the upper silicone connecting ring is arranged on the top of the inner wall of the drying tower and outside the air outlet, and both the upper silicone connecting ring and the lower silicone connecting ring are flexible structures.

[0009] Furthermore, the shapes of the stainless steel screen and the filter are adapted to the shape of the drying tower, and there is a gap between the outer wall of the stainless steel screen and the inner wall of the drying tower.

[0010] Furthermore, the lower silicone connecting ring is arranged inside the discharge port at the bottom of the inner wall of the drying tower, and the stainless steel screen is connected to the drying tower through the upper silicone connecting ring and the lower silicone connecting ring.

[0011] Furthermore, a distributor motor is arranged in the middle of the surface of the air filter heater, and the bottom end of the output shaft of the distributor motor penetrates the top of the drying tower and is connected to a blanking assembly.

[0012] Furthermore, the blanking assembly includes an extension rod, a linkage drum and a servo motor. The linkage drum is fixed to the bottom of the extension rod, and the servo motor is fixed to the top of the inner wall of the linkage drum.

[0013] Furthermore, the blanking assembly also includes a winding drum and a wire rope. The end of the bottom output shaft of the servo motor is connected to the winding drum, and the wire rope is wound inside the winding drum.

[0014] Furthermore, the blanking assembly also includes an impact ball, and the end of the wire rope is provided with an impact ball.

[0015] Furthermore, the blanking assembly also includes a stress-bearing arc surface, the inner surface of the stainless steel screen is fixed with the stress-bearing arc surface, and the height of the stress-bearing arc surface is consistent with the height of the winding reel.

[0016] A dietary fiber for reducing oil and sugar absorption, the preparation process of which uses the above-mentioned preparation machine, the dietary fiber for reducing oil and sugar absorption includes the following raw materials by weight:

[0017] 0.5g fiber powder; 0.2g isomaltooligosaccharide; 0.5g konjac flour; 0.6g resistant dextrin; 0.1g citrus fiber; 0.1g oat fiber; 0.003g Lactobacillus rhamnosus LRa05; 0.01g silicon dioxide; 0.003g Bifidobacterium lactis BLa80;

[0018] Based on the above raw materials, a process for preparing dietary fiber for reducing oil and sugar absorption is as follows:

[0019] Step 1: Mix and moisten the fiber powder, isomaltooligosaccharide, konjac flour, resistant dextrin, citrus fiber, oat fiber, Lactobacillus rhamnosus LRa05, silicon dioxide, and Bifidobacterium lactis BLa80 for 10 minutes, and then ultrafine grind the reacted materials to 20 microns and then perform radio frequency treatment, the radio frequency frequency is 27 MHz, the power is 15 KW, the treatment time is 100 minutes, and the pH of the dietary fiber after radio frequency treatment is adjusted to 4.5 to obtain the wet material to be dried;

[0020] Step 2: The wet material is transferred to the inside of the wet material box, and the wet material is sent to the atomizing nozzle along the pipeline by the feeding pump to be sprayed from the top of the inner wall of the drying tower, wherein the atomizing nozzle is distributed in a ring shape and sprays the atomized wet material in an inclined shape toward the inner wall of the drying tower.

[0021] At the same time, the outside air is heated and filtered by the air filter heater and then blown down from the top of the drying tower evenly through the air filter heater, so that the atomized wet material contacts with the hot air after being sprayed out to remove moisture and achieve drying;

[0022] Step 3: After drying, the powdered material is confined inside the filter and falls down. At this time, part of the material will adhere to the inner surface of the filter, while the air will pass through the filter and stainless steel screen and be discharged directly outward along the exhaust pipe, and the remaining powdered material will be discharged from the discharge port at the bottom of the drying tower;

[0023] Step 4: For the powdered material attached to the inner surface of the filter, the distributor motor drives the fan blades inside the hot air distributor to rotate to enhance the heat exchange between the hot air and the wet material and the swirl descent, and at the same time, it also drives the extension rod and the linked drum to rotate. The servo motor is started by remote control to drive the reel to rotate, so that the rope is released under the gravity of the impact ball, and the impact ball rotates through the extended rope under the action of the linked drum under the centrifugal force. During the rotation process, the force arc surface is frequently impacted based on the rotation speed. After the force arc surface is stressed, the impact force is dispersed to the entire stainless steel screen. The stainless steel screen vibrates inside the drying tower under the flexible action of the upper silicone connecting ring and the lower silicone connecting ring, thereby shaking off the material attached to the inner surface of the filter, so that the material is discharged along the discharge port at the bottom of the drying tower.

[0024] The present invention provides a dietary fiber for reducing oil and sugar absorption and a preparation machine thereof, which has the following beneficial effects:

[0025] 2. The dietary fiber that reduces the absorption of oil and sugar and the preparation machine thereof can separate the solid and gas of the dried powdered material by arranging stainless steel screens and filters that match the shape of the drying tower, so that the hot gas can be directly discharged to the outside from the exhaust pipe without the need for additional cyclone separators. This reduces the installation cost while optimizing the equipment volume and can further improve the dietary fiber preparation efficiency.

[0026] 1. The dietary fiber for reducing oil and sugar absorption and the preparation machine thereof, while realizing solid-gas separation of materials through the filter screen, utilizes the rotation of the output shaft of the distributor motor to drive the impact ball to rotate based on the rotation speed under the action of centrifugal force, and frequently collides with the force-bearing arc surface during the rotation process, thereby converting the collision into a vibration force and applying it to the entire stainless steel screen, thereby carrying the filter screen to vibrate to shake off the material attached to its inner surface, so that the dried powdered material can be quickly discharged from the discharge port, and solves the problem that the filter screen is affected by the material attachment and the filtering effect is affected.

[0033] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a preparation machine, including a drying tower 1 and a filtering assembly 7, a hot air distributor 2 is arranged on the top of the drying tower 1, and an air filter heater 3 is connected to the end of the hot air distributor 2, an atomizing nozzle 4 is arranged on the inner side of the air outlet at the top of the inner wall of the drying tower 1, and the atomizing nozzle 4 is sequentially connected to a feed pump 5 and a wet material box 6 through a pipeline, and the filtering assembly 7 is arranged inside the drying tower 1, and the filtering assembly 7 includes an upper silicone connecting ring 701, a stainless steel screen 702, a filter 703, a lower silicone connecting ring 704 and an exhaust pipe 705, the bottom of the upper silicone connecting ring 701 is connected to the stainless steel screen 702, and the inner wall of the stainless steel screen 702 is closely attached to the filter 703, and the stainless steel screen A lower silicone connecting ring 704 is sleeved on the bottom of the outer wall of the net 702, an exhaust pipe 705 is connected to the lower part of the outer side of the drying tower 1, and the exhaust pipe 705 is connected to the inside of the drying tower 1, an upper silicone connecting ring 701 is arranged on the top of the inner wall of the drying tower 1 on the outside of the air outlet, and the upper silicone connecting ring 701 and the lower silicone connecting ring 704 are both flexible structures, the shapes of the stainless steel screen 702 and the filter 703 are adapted to the shape of the drying tower 1, and there is a gap between the outer wall of the stainless steel screen 702 and the inner wall of the drying tower 1, the lower silicone connecting ring 704 is arranged inside the discharge port at the bottom of the inner wall of the drying tower 1, and the stainless steel screen 702 is connected to the drying tower 1 through the upper silicone connecting ring 701 and the lower silicone connecting ring 704;

[0035] The specific operation is as follows: the dietary fiber wet material is transferred to the inside of the wet material box 6, and the wet material is sent to the atomizing nozzle 4 along the pipeline through the feeding pump 5 to be sprayed out from the top of the inner wall of the drying tower 1. At the same time, the outside air is heated and filtered by the air filter heater 3 and then evenly blown downward from the top of the drying tower 1 through the air filter heater 3, so that the atomized wet material contacts with the hot air after being sprayed out to remove moisture and achieve drying. Since the wet material is located inside the filter screen 703 during drying, the powdered material formed after the wet material is dried will adhere to the inner surface of the filter screen 703 because its particle size is smaller than the aperture of the filter screen 703, and the hot air flow can pass through the filter screen 703 and the stainless steel screen 702 and be directly discharged from the exhaust pipe 705.

[0036] Based on the above description, the present invention can separate the solid and gas of the dried powdered material by arranging stainless steel screens 702 and filters 703 that match the shapes of the stainless steel screens 702 and 703 inside the drying tower 1, so that the hot gas can be directly discharged to the outside from the exhaust pipe 705 without the need for additional cyclone separators. This reduces the installation cost while optimizing the equipment volume and can further improve the efficiency of dietary fiber preparation.

[0037] like Figure 1-Figure 5 As shown, a distributor motor 8 is provided in the middle of the surface of the air filter heater 3, and the bottom end of the output shaft of the distributor motor 8 passes through the top of the drying tower 1 and is connected to a blanking assembly 9, the blanking assembly 9 includes an extension rod 901, a linkage drum 902 and a servo motor 903, the bottom of the extension rod 901 is fixed with a linkage drum 902, and the top of the inner wall of the linkage drum 902 is fixed with a servo motor 903, the blanking assembly 9 also includes a winding disk 904 and a wire rope 905, the bottom end of the output shaft of the servo motor 903 is connected with the winding disk 904, and the inside of the winding disk 904 is wound with the wire rope 905, the blanking assembly 9 also includes an impact ball 906, and the end of the wire rope 905 is provided with an impact ball 906, the blanking assembly 9 also includes a force-bearing arc surface 907, the inner surface of the stainless steel screen 702 is fixed with a force-bearing arc surface 907, and the height of the force-bearing arc surface 907 is consistent with the height of the winding disk 904;

[0038] The specific operation is as follows: the atomizing nozzle 4 is distributed in a ring shape and sprays the atomized wet material in an inclined shape toward the inner wall of the drying tower 1. When the wet material is sprayed in an atomized shape, it will not contact the outer wall of the extension rod 901 and the interlocking drum 902 based on the inclination angle, thereby preventing the dried powdered material from adhering to the outer wall of the extension rod 901 and the interlocking drum 902. Since the powdered material will adhere to the inner wall of the filter screen 703 after drying, for the powdered material attached to the inner surface of the filter screen 703, the distributor motor 8 drives the fan blades inside the hot air distributor 2 to rotate to enhance the heat exchange between the hot air and the wet material and the swirl descent, and at the same time, it will also drive the extension rod 901 and the interlocking drum 902 to rotate, and the remote control starts the servo motor 8. The motor 903 drives the winding disk 904 to rotate, so that the wire rope 905 is released under the gravity of the impact ball 906, and the impact ball 906 rotates through the extended wire rope 905 under the rotation of the linked drum 902, and frequently impacts the force-bearing arc surface 907 based on the rotation speed during the rotation process. After the force-bearing arc surface 907 is stressed, the impact force is dispersed to the entire stainless steel screen 702. The stainless steel screen 702 vibrates inside the drying tower 1 under the flexible action of the upper silicone connecting ring 701 and the lower silicone connecting ring 704, thereby shaking off the material attached to the inner surface of the filter screen 703, so that the material is discharged along the discharge port at the bottom of the drying tower 1;

[0039] The force-bearing arc surface 907 is provided with reinforcing ribs inside to prevent it from deforming during the impact process;

[0040] Based on the above description, the present invention realizes solid-gas separation of materials through the filter screen 703, and utilizes the rotation of the output shaft of the distributor motor 8 to drive the impact ball 906 to rotate based on the speed under the action of centrifugal force, and frequently collides with the force-bearing arc surface 907 during the rotation process, thereby converting the collision into a vibration force and applying it to the entire stainless steel screen 702, thereby carrying the filter screen 703 to vibrate to shake off the material attached to its inner surface, so that the dried powdered material can be quickly discharged from the discharge port, and solves the problem that the filter screen 703 is affected by the material attachment. The filtering effect;

[0041] Secondly, since the impact ball 906 will produce sound when it hits the force-bearing arc surface 907, in order to prevent the noise from occurring for a long time, when there is no need to apply vibration force to the filter 703, the servo motor 903 is used to reversely rotate the winding disk 904 to wind up the rope 905, thereby shortening the rotation radius of the impact ball 906, thereby avoiding noise generated by collision.

[0042] A dietary fiber for reducing oil and sugar absorption, the preparation process of which uses the above-mentioned preparation machine, the dietary fiber for reducing oil and sugar absorption includes the following raw materials by weight:

[0043] 0.5g fiber powder; 0.2g isomaltooligosaccharide; 0.5g konjac flour; 0.6g resistant dextrin; 0.1g citrus fiber; 0.1g oat fiber; 0.003g Lactobacillus rhamnosus LRa05; 0.01g silicon dioxide; 0.003g Bifidobacterium lactis BLa80;

[0044] By adding citrus fiber and resistant dextrin, they can synergistically reduce fasting and postprandial blood glucose levels. This synergistic effect may be due to the fact that citrus fiber and resistant dextrin affect glucose metabolism through complementary mechanisms, slowing down the digestion and absorption of carbohydrates and delaying the increase in blood glucose levels. In addition, citrus fiber regulates glucose metabolism by regulating the secretion of incretin hormones in the gastrointestinal tract. These effects jointly affect insulin secretion and the cellular response to insulin, thereby regulating blood glucose metabolism.

[0045] By selecting dietary fibers from different sources, a composite dietary fiber with a high barrier effect on sugars and fats in the intestine is prepared. At the same time, the composite dietary fiber can adjust intestinal microorganisms, thereby affecting the host's energy balance and increasing the body's heat excreted from feces, so as to achieve the effect of reducing oil and sugar absorption.

[0046] Based on the above raw materials, a process for preparing dietary fiber for reducing oil and sugar absorption is as follows:

[0047] Step 1: Mix and moisten the fiber powder, isomaltooligosaccharide, konjac flour, resistant dextrin, citrus fiber, oat fiber, Lactobacillus rhamnosus LRa05, silicon dioxide, and Bifidobacterium lactis BLa80 for 10 minutes, and then ultrafine grind the reacted materials to 20 microns and then perform radio frequency treatment, the radio frequency frequency is 27 MHz, the power is 15 KW, the treatment time is 100 minutes, and the pH of the dietary fiber after radio frequency treatment is adjusted to 4.5 to obtain the wet material to be dried;

[0048] Step 2: The wet material is transferred to the inside of the wet material box 6, and the wet material is sent to the atomizing nozzle 4 along the pipeline by the feeding pump 5 so as to be sprayed out from the top of the inner wall of the drying tower 1, wherein the atomizing nozzle 4 is distributed in a ring shape and sprays the atomized wet material in an inclined shape toward the inner wall of the drying tower 1. When the wet material is sprayed in an inclined shape, it will not contact the outer wall of the extension rod 901 or the linked rotating drum 902 due to the inclination angle;

[0049] At the same time, the outside air is heated and filtered by the air filter heater 3 and then blown down from the top of the drying tower 1 evenly through the air filter heater 3, so that the atomized wet material contacts with the hot air after being sprayed out to remove moisture and achieve drying;

[0050] Step 3: After drying, the powdered material is confined inside the filter 703 and falls down. At this time, part of the material will adhere to the inner surface of the filter 703, while the air passes through the filter 703 and the stainless steel screen 702 and is directly discharged outward along the exhaust pipe 705, and the remaining powdered material is discharged from the discharge port at the bottom of the drying tower 1;

[0051] Step 4: For the powdery material attached to the inner surface of the filter screen 703, the distributor motor 8 drives the fan blades inside the hot air distributor 2 to rotate to enhance the heat exchange between the hot air and the wet material and the swirl flow, and at the same time drives the extension rod 901 and the linkage drum 902 to rotate, and remote control starts the servo motor 903 to drive the winding disk 904 to rotate, so that the wire rope 905 is released under the gravity of the impact ball 906, and the impact ball 906 is centrifugally driven under the rotation of the linkage drum 902. The extended wire rope 905 is rotated and frequently impacts the force-bearing arc surface 907 based on the rotation speed during the rotation. After the force-bearing arc surface 907 is stressed, the impact force is dispersed to the entire stainless steel screen 702. The stainless steel screen 702 vibrates inside the drying tower 1 under the flexible action of the upper silicone connecting ring 701 and the lower silicone connecting ring 704, thereby shaking off the material attached to the inner surface of the filter screen 703, so that the material is discharged along the discharge port at the bottom of the drying tower 1, thereby obtaining dietary fiber.

[0052] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.

The stainless steel screen (702) vibrates inside the drying tower (1) under the flexible action of the upper silicone connecting ring (701) and the lower silicone connecting ring (704), thereby shaking off the material attached to the inner surface of the filter screen (703), so that the material is discharged from the discharge port at the bottom of the drying tower (1).
