Description

Technical Field

[0001] The invention belongs to the technical field of maltose production, and particularly relates to a device for increasing the content of maltitol. Background Art

[0002] Maltose is a disaccharide composed of two glucose molecules connected by an α-1,4 glycosidic bond, also known as maltobiose, which is widely used in many industries such as food, beverages, and medicine. The existing maltose production process mainly includes pretreatment, liquefaction, saccharification, and concentration. There are many ways to increase the maltitol content, and the most common way is to improve the saccharification process.

[0003] The saccharification process of the prior art; after liquefaction is completed, the liquefied liquid is filtered to remove excess impurities to obtain a substrate suitable for saccharification. Then, pullulanase is added to the substrate for saccharification, and finally, β-amylase is added to continue saccharification. Among them, pullulanase can cut the α-1,6-glycosidic bond in the branch point of amylose to form a straight chain, making the substrate easier to be acted on by β-amylase; β-amylase mainly acts on pullulanase to cut the amylose. β-amylase cuts the separated α-1,4 bonds at a time and decomposes it into two glucose groups in sequence.

[0004] In the above saccharification process, since the pH of the saccharification process is close to neutral and the temperature does not reach the Pasteur sterilization temperature, some heat-resistant and acid-resistant microorganisms are easy to grow. For example, thermophilic lactobacilli and other bacteria will consume the produced sugar, multiply in large numbers and produce acid, causing the pH value of saccharification to drop rapidly to outside the effective range of the enzyme, resulting in the enzyme being unable to function normally. Summary of the invention

[0005] The purpose of the present invention is to provide a device for increasing the content of maltitol in view of the shortcomings of the prior art, so as to solve the technical problems in the prior art.

[0006] The object of the present invention can be achieved by the following technical scheme: a device for increasing the content of maltitol, comprising a saccharification tank and a cylinder installed on the top of the saccharification tank, the output end of the cylinder is connected to a filtering component, a single-layer filter membrane is installed in the saccharification tank, a liquid inlet is installed on the top of the saccharification tank, the liquid inlet is connected to the liquefied liquid, a heating component and a liquid inlet component are respectively installed on the side walls of the saccharification tank, and a liquid discharge port is installed at the bottom of the saccharification tank; the filtering component comprises a push plate and a through-hole base plate, the output end of the cylinder is connected to the push plate, the push plate is connected to the through-hole base plate through a connecting rod, the single-layer filter membrane is arranged between the push plate and the through-hole base plate, the push plate and the through-hole base plate form a fixed material cavity in the saccharification tank, and the liquid inlet is connected to the fixed material cavity through a threaded hose; when in use, the liquefied liquid is transported to the fixed material cavity through the liquid inlet, and then a certain amount of lysozyme is injected into the fixed material cavity through the liquid inlet component, and after the lysozyme hydrolyzes the miscellaneous bacteria in the liquefied liquid, the cylinder pushes the liquefied liquid in the fixed material cavity through the single-layer filter membrane.

[0007] As a further optimization or improvement of this solution, the interior of the saccharification tank is divided into a sterilization chamber, a saccharification chamber one and a saccharification chamber two. The sterilization chamber and the saccharification chamber one are separated by a single-layer filter membrane, and the saccharification chamber one and the saccharification chamber two are separated by two layers of ultrafiltration membranes.

[0008] As a further optimization or improvement of this scheme, the heating supply component includes heating plate one, heating plate two and heating plate three, the liquid inlet component includes liquid inlet pipe one, liquid inlet pipe two and liquid inlet pipe three, heating plate one and liquid inlet pipe one are respectively installed on the outside of the sterilization chamber, heating plate two and liquid inlet pipe two are respectively installed on the outside of the saccharification chamber one, and heating plate three and liquid inlet pipe three are respectively installed on the outside of the saccharification chamber two.

[0010] As a further optimization or improvement of this solution, a stirring assembly is installed at the bottom of the through-hole turntable.

[0011] As a further optimization or improvement of this solution, a fixing plate is installed at the bottom of the through-hole turntable, a threaded rod is installed on the fixing plate, an internal threaded tube is rotatably installed in the saccharification chamber, a stirring blade is installed on the internal threaded tube, and the internal threaded tube is transmission-connected to the threaded rod.

[0012] As a further optimization or improvement of this solution, the second liquid inlet tube is connected to pullulanase; and the third liquid inlet tube is connected to β-amylase.

[0013] Beneficial effects of the present invention: (1) The present invention eliminates miscellaneous bacteria in the liquefied liquid by adding lysozyme to the liquefied liquid, thereby increasing the maltitol content. The push plate and the through-hole base plate form a fixed material cavity, and a fixed amount of lysozyme is added according to the specified capacity inside the fixed material cavity to avoid excessive lysozyme, which may cause the lysozyme to affect the beneficial bacteria.

[0014] Specifically, the present invention uses a cylinder to drive the dosing chamber downward to filter the hydrolyzed impurities in the liquefied liquid inside the dosing chamber through a single-layer filter membrane, thereby preventing the impurities produced by the lysozyme hydrolyzing bacteria from competitively inhibiting the saccharifying enzyme and affecting the enzyme activity and saccharification efficiency.

[0015] (2) The two-layer ultrafiltration membrane of the present invention is a double-layer ultrafiltration membrane, wherein one layer of the ultrafiltration membrane is used to block the macromolecular starch in the bottom liquid, and when pullulanase cuts the starch into linear chains, the starch can pass through the two layers of ultrafiltration membrane; the other layer of the ultrafiltration membrane is used to separate pullulanase and β-amylase, ensuring that the pullulanase is located in the saccharification chamber 1 and the β-amylase is located in the saccharification chamber 2, and at the same time, the saccharification chamber 1 and the saccharification chamber 2 are coordinated to bring the pullulanase and β-amylase into optimal activity.

[0016] The present invention blocks the macromolecular starch in the bottom liquid in the first saccharification chamber through two layers of ultrafiltration membranes, so that the pullulanase in the best activity state cuts the starch into straight chains before entering the second saccharification chamber, ensuring that the beta-amylase in the second saccharification chamber mainly decomposes the straight-chain starch decomposed by the pullulanase again, avoiding the beta-amylase from acting on the starch not decomposed by the pullulanase, resulting in the premature consumption of the beta-amylase, and finally causing the phenomenon of incomplete saccharification.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 6 , a device for increasing the content of maltitol, comprising a saccharification tank 1 and a cylinder 2 installed on the top of the saccharification tank 1, the output end of the cylinder 2 is connected to a filter assembly 6, a single-layer filter membrane 11 is installed in the saccharification tank 1, a liquid inlet 3 is installed on the top of the saccharification tank 1, the liquid inlet 3 is connected to a liquefied liquid, a heating assembly 4 and a liquid inlet assembly 8 are respectively installed on the side walls of the saccharification tank 1, and a liquid discharge port 9 is installed at the bottom of the saccharification tank 1; the filter assembly 6 comprises a push plate 601 and a through-hole base plate 602, the output end of the cylinder 2 is connected to the push plate 601, the push plate 601 It is connected to the through-hole base plate 602 through a connecting rod 606, and the single-layer filter membrane 11 is arranged between the push plate 601 and the through-hole base plate 602. The push plate 601 and the through-hole base plate 602 form a fixed-feeding chamber in the saccharification tank 1, and the liquid inlet 3 is connected to the fixed-feeding chamber through a threaded hose 5; when in use, the liquefied liquid is transported to the fixed-feeding chamber through the liquid inlet 3, and then a certain amount of lysozyme is injected into the fixed-feeding chamber through the liquid inlet component 8. After the lysozyme hydrolyzes the miscellaneous bacteria in the liquefied liquid, the cylinder 2 pushes the liquefied liquid in the fixed-feeding chamber through the single-layer filter membrane 11.

[0030] Specifically, a through-hole turntable 604 is rotatably installed at the bottom of the through-hole base plate 602, a fixed box 608 is installed at the bottom of the through-hole turntable 604, a slide plate 609 is slidably installed in the fixed box 608, a slide bar 1 605 and a slide bar 2 607 are respectively installed at both ends of the slide plate 609, an electromagnet 610 is symmetrically installed on the inner wall of the fixed box 608, and the electromagnet 610 adsorbs the slide plate 609. The two side walls of the saccharification chamber 102 are respectively provided with a positive J-shaped groove 13 and an inverted J-shaped groove 14 which are symmetrical up and down, the slide bar 2 607 is slidably matched with the inverted J-shaped groove 14, and the slide bar 1 605 is slidably matched with the positive J-shaped groove 13.

[0031] It should be noted that see Figure 2 In the initial state, the metering chamber composed of the push plate 601 and the through-hole base plate 602 is located in the sterilization chamber 101. At this time, the through-hole base plate 602 is located on one side of the single-layer filter membrane 11, and the push plate 601 is located on the other side of the single-layer filter membrane 11. The through-hole turntable 604 blocks the through-hole base plate 602, so that the metering chamber is in a sealed state.

[0032] When in use, the liquefied liquid is added into the dosing chamber through the liquid inlet 3. When the capacity of the dosing chamber reaches the specified amount, the liquid inlet 3 is closed, and the liquid inlet pipe 801 is opened. Lysozyme is injected into the dosing chamber through the liquid inlet pipe 801 according to a certain proportion. After the lysozyme hydrolyzes the bacteria in the liquefied liquid, the cylinder 2 is started, and the cylinder 2 drives the dosing chamber to move downward. At this time, the push plate 601 pushes the hydrolyzed impurities in the liquefied liquid inside the dosing chamber to be filtered through the single-layer filter membrane 11. In this process, the optimal activity of lysozyme is exerted by adjusting the heating plate 401.

[0033] The present invention eliminates the miscellaneous bacteria in the liquefied liquid by adding lysozyme to the liquefied liquid, thereby increasing the maltitol content. In order to avoid excessive lysozyme, which may affect the beneficial bacteria, the present invention forms a fixed material cavity by a push plate 601 and a through-hole base plate 602, and adds a certain amount of lysozyme according to the specified capacity inside the fixed material cavity. The impurities produced by the hydrolysis of bacteria by lysozyme will competitively inhibit the saccharifying enzyme, affecting the activity of the enzyme and the saccharification efficiency. Therefore, the present invention drives the fixed material cavity to move downward by the cylinder 2, and the hydrolyzed impurities in the liquefied liquid inside the fixed material cavity are filtered through a single-layer filter membrane 11.

[0034] It should be noted that, in the initial state, the slide bar 1 605 is inserted into the positive J-shaped groove 13, at which time the slide bar 1 605 is in sliding cooperation with the positive J-shaped groove 13, and the slide bar 2 607 is separated from the inverted J-shaped groove 14. The positive J-shaped groove 13 is a J-shaped design, and when the slide bar 1 605 initially slides along the vertical section of the positive J-shaped groove 13, the states of the through-hole base plate 602 and the through-hole rotating disk 604 remain unchanged, and the through-hole rotating disk 604 blocks the through-hole base plate 602; when the slide bar 1 605 slides to the tail end of the positive J-shaped groove 13, the slide bar 1 605 and the through-hole rotating disk 604 rotate, so that the through-hole rotating disk 604 overlaps with the through-hole on the through-hole base plate 602, and at this time the through-hole base plate 602 is in a liquid-passing state, and the bottom liquid inside the fixed material cavity all enters the saccharification cavity 102. The inverted J-shaped groove 14 is an inverted J-shaped design, and its working principle is the same as that of the slide bar 1 605 and the positive J-shaped groove 13.

[0035] As the cylinder 2 is started, the cylinder 2 drives the metering chamber to move from the sterilization chamber 101 toward the saccharification chamber 102, and the push plate 601 pushes the liquefied liquid inside the metering chamber to be filtered through the single-layer filter membrane 11, and the filtered bottom liquid enters the saccharification chamber 102 through the single-layer filter membrane 11. At the same time, the slide bar 605 at the bottom of the through-hole turntable 604 slides in the regular J-shaped groove 13. When the liquefied liquid inside the metering chamber completely passes through the single-layer filter membrane 11, the slide bar 605 slides to the tail end of the regular J-shaped groove 13, and the slide bar 605 and the through-hole turntable 604 rotate to make the through-hole turntable 604 coincide with the through-hole on the through-hole base plate 602. At this time, the through-hole base plate 602 is in a liquid-passing state, and the bottom liquid inside the metering chamber all enters the saccharification chamber 102.

[0036] When the fixed material chamber needs to return, the cylinder 2 drives the push plate 601 and the through hole base plate 602 to move upward, and at the same time, the electromagnet 610 is started. The electromagnet 610 adsorbs the slide plate 609, so that the slide bar 1 605 is separated from the positive J-shaped groove 13, and the slide bar 2 607 is inserted into the inverted J-shaped groove 14. As the cylinder 2 drives the fixed material chamber to move upward, the through hole base plate 602 is in a liquid-passing state, which prevents the through hole base plate 602 from extracting the bottom liquid inside the saccharification chamber 2 103 toward the saccharification chamber 1 102, causing damage to the two layers of ultrafiltration membrane 12. After the slide bar 2 607 reaches the top of the inverted J-shaped groove 14, the through hole turntable 604 rotates and blocks the through hole base plate 602. It should be noted that a sealing gasket 603 is installed at the bottom of the through hole base plate 602 to improve the sealing performance of the through hole base plate 602 and the sealing gasket 603.

[0037] See also Figure 1-Figure 5 The interior of the saccharification tank 1 is divided into a sterilization chamber 101, a saccharification chamber 1 102 and a saccharification chamber 2 103. The sterilization chamber 101 and the saccharification chamber 1 102 are separated by a single-layer filter membrane 11, and the saccharification chamber 1 102 and the saccharification chamber 2 103 are separated by two layers of ultrafiltration membranes 12.

[0038] Specifically, the heating component 4 includes a heating plate 1 401, a heating plate 2 402 and a heating plate 3 403, the liquid inlet component 8 includes a liquid inlet pipe 1 801, a liquid inlet pipe 2 802 and a liquid inlet pipe 3 803, the heating plate 1 401 and the liquid inlet pipe 1 801 are respectively installed on the outside of the sterilization chamber 101, the heating plate 2 402 and the liquid inlet pipe 2 802 are respectively installed on the outside of the saccharification chamber 102, and the heating plate 3 403 and the liquid inlet pipe 3 803 are respectively installed on the outside of the saccharification chamber 2 103.

[0039] Specifically, the second liquid inlet pipe 802 is connected to pullulanase; and the third liquid inlet pipe 803 is connected to β-amylase.

[0040] It should be noted that the saccharification method of the prior art is to first add pullulanase to the base liquid and finally add β-amylase, but this method has the following technical problems: first, the optimal activity temperatures of pullulanase and β-amylase are different. When pullulanase and β-amylase work together, the activity of one of them is inevitably suppressed, thereby affecting the saccharification efficiency; second, when pullulanase has not yet cut all the starch in the base liquid into straight chains, β-amylase is added. β-amylase will decompose the uncut starch, causing the pullulanase to lack a target, resulting in excessive pullulanase residue; as the target of β-amylase increases, the β-amylase is consumed prematurely, ultimately resulting in incomplete saccharification.

[0041] It should be noted that the two layers of ultrafiltration membrane 12 are double-layer ultrafiltration membranes, one of which is used to block the macromolecular starch in the bottom liquid. When pullulanase cuts the starch into linear chains, it can pass through the two layers of ultrafiltration membrane 12; the other layer of ultrafiltration membrane is used to block and separate pullulanase and β-amylase, ensuring that the pullulanase is located in the saccharification chamber 1 102 and the β-amylase is located in the saccharification chamber 2 103, and at the same time cooperates with the saccharification chamber 1 102 and the saccharification chamber 2 103 to bring the pullulanase and β-amylase into optimal activity.

[0042] The present invention uses two layers of ultrafiltration membranes 12 to block the macromolecular starch in the bottom liquid inside the saccharification chamber 102, so that the pullulanase in the optimal activity state cuts the starch into linear chains before entering the saccharification chamber 2 103, ensuring that the β-amylase in the saccharification chamber 2 103 mainly decomposes the linear starch decomposed by the pullulanase again, avoiding the β-amylase from acting on the starch not decomposed by the pullulanase, resulting in the premature consumption of the β-amylase, and finally causing the phenomenon of incomplete saccharification.

[0043] Pullulanase is added to the saccharification chamber 102 through the liquid inlet pipe 802, and the starch in the bottom liquid is cut into straight chains by the pullulanase. The decomposed straight-chain starch enters the saccharification chamber 2 103 through two layers of ultrafiltration membranes 12, and then β-amylase is added to the saccharification chamber 2 103 through the liquid inlet pipe 803, so that the β-amylase mainly acts on the straight-chain starch cut by the pullulanase to ensure thorough saccharification.

[0044] Specifically, when the cylinder 2 drives the push plate 601 and the through-hole base plate 602 to move downward, since the through-hole turntable 604 blocks the through-hole base plate 602, the through-hole base plate 602 and the through-hole turntable 604 will compress the air inside the saccharification chamber 102, accelerate the straight-chain starch inside the saccharification chamber 102 to pass through the two layers of ultrafiltration membrane 12, and improve the saccharification rate.

[0045] See also Figure 2-Figure 6 A stirring assembly 7 is installed at the bottom of the through-hole turntable 604.

[0046] A fixing plate 701 is installed at the bottom of the through-hole turntable 604 , a threaded rod 702 is installed on the fixing plate 701 , an internal threaded tube 704 is rotatably installed in the saccharification chamber 102 , a stirring blade 703 is installed on the internal threaded tube 704 , and the internal threaded tube 704 is transmission-connected to the threaded rod 702 .

[0047] It should be noted that when the cylinder 2 is running, the threaded rod 702 at the bottom of the through-hole turntable 604 moves synchronously with the through-hole turntable 604. Through the threaded connection between the threaded rod 702 and the internal threaded tube 704, the movement of the threaded rod 702 drives the internal threaded tube 704 and the stirring blade 703 to rotate, thereby stirring the bottom liquid inside the saccharification chamber 102 and accelerating the saccharification efficiency.

[0048] The implementation principle of the present invention is: in the initial state, the material fixing chamber composed of the push plate 601 and the through-hole base plate 602 is located in the sterilization chamber 101. At this time, the through-hole base plate 602 is located on one side of the single-layer filter membrane 11, and the push plate 601 is located on the other side of the single-layer filter membrane 11. The through-hole turntable 604 blocks the through-hole base plate 602, so that the material fixing chamber is in a sealed state.

[0049] When in use, the liquefied liquid is added into the dosing chamber through the liquid inlet 3. When the capacity of the dosing chamber reaches the specified amount, the liquid inlet 3 is closed, and the liquid inlet pipe 801 is opened. Lysozyme is injected into the dosing chamber through the liquid inlet pipe 801 according to a certain proportion. After the lysozyme hydrolyzes the bacteria in the liquefied liquid, the cylinder 2 is started, and the cylinder 2 drives the dosing chamber to move downward. At this time, the push plate 601 pushes the hydrolyzed impurities in the liquefied liquid inside the dosing chamber to be filtered through the single-layer filter membrane 11. In this process, the optimal activity of lysozyme is exerted by adjusting the heating plate 401.

[0050] As the cylinder 2 is started, the cylinder 2 drives the metering chamber to move from the sterilization chamber 101 toward the saccharification chamber 102, and the push plate 601 pushes the liquefied liquid in the metering chamber to be filtered through the single-layer filter membrane 11, and the filtered bottom liquid enters the saccharification chamber 102 through the single-layer filter membrane 11, and at the same time, the slide bar 605 at the bottom of the through-hole turntable 604 slides in the regular J-shaped groove 13. When the liquefied liquid in the metering chamber completely passes through the single-layer filter membrane 11, the slide bar 605 slides to the tail end of the regular J-shaped groove 13. Under the cooperation of the slide bar 605 and the regular J-shaped groove 13, the slide bar 605 and the through-hole turntable 604 rotate, so that the through-hole turntable 604 coincides with the through-hole on the through-hole base plate 602. At this time, the through-hole base plate 602 is in a liquid-passing state, and the bottom liquid in the metering chamber all enters the saccharification chamber 102.

[0051] Pullulanase is added to the saccharification chamber 102 through the liquid inlet pipe 802, and the starch in the bottom liquid is cut into straight chains by the pullulanase. The decomposed straight-chain starch enters the saccharification chamber 2 103 through two layers of ultrafiltration membranes 12, and then β-amylase is added to the saccharification chamber 2 103 through the liquid inlet pipe 803, so that the β-amylase mainly acts on the straight-chain starch cut by the pullulanase to ensure thorough saccharification.

[0052] When the dosing chamber needs to return, the cylinder 2 drives the push plate 601 and the through-hole base plate 602 to move upward, and at the same time, the electromagnet 610 is activated, and the electromagnet 610 attracts the slide plate 609, so that the slide bar 1 605 is separated from the positive J-shaped groove 13, and the slide bar 2 607 is inserted into the inverted J-shaped groove 14. As the cylinder 2 drives the dosing chamber to move upward, the through-hole base plate 602 is in a liquid-passing state, so as to prevent the through-hole base plate 602 from drawing the bottom liquid inside the saccharification chamber 2 103 toward the saccharification chamber 1 102, causing damage to the two layers of ultrafiltration membranes 12. After the slide bar 2 607 reaches the top of the inverted J-shaped groove 14, the through-hole turntable 604 rotates and blocks the through-hole base plate 602.

[0053] Specifically, the two layers of ultrafiltration membrane 12 are double-layer ultrafiltration membranes, one of which is used to block the macromolecular starch in the bottom liquid. When pullulanase cuts the starch into linear chains, it can pass through the two layers of ultrafiltration membrane 12; the other layer of ultrafiltration membrane is used to separate pullulanase and β-amylase, ensuring that the pullulanase is located in saccharification chamber 1 102 and the β-amylase is located in saccharification chamber 2 103. At the same time, saccharification chamber 1 102 and saccharification chamber 2 103 are coordinated to bring the pullulanase and β-amylase into optimal activity.

[0054] The present invention uses two layers of ultrafiltration membranes 12 to block the macromolecular starch in the bottom liquid inside the saccharification chamber 102, so that the pullulanase in the optimal activity state cuts the starch into linear chains before entering the saccharification chamber 2 103, ensuring that the β-amylase in the saccharification chamber 2 103 mainly decomposes the linear starch decomposed by the pullulanase again, avoiding the β-amylase from acting on the starch not decomposed by the pullulanase, resulting in the premature consumption of the β-amylase, and finally causing the phenomenon of incomplete saccharification.

[0055] Specifically, when the cylinder 2 is running, the threaded rod 702 at the bottom of the through-hole turntable 604 moves synchronously with the through-hole turntable 604. Through the threaded connection between the threaded rod 702 and the internal threaded tube 704, the movement of the threaded rod 702 drives the internal threaded tube 704 and the stirring blade 703 to rotate, thereby stirring the bottom liquid inside the saccharification chamber 102 and accelerating the saccharification efficiency.

[0056] Specifically, when the cylinder 2 drives the push plate 601 and the through-hole base plate 602 to move downward, since the through-hole turntable 604 blocks the through-hole base plate 602, the through-hole base plate 602 and the through-hole turntable 604 will compress the air inside the saccharification chamber 102, accelerate the straight-chain starch inside the saccharification chamber 102 to pass through the two layers of ultrafiltration membrane 12, and improve the saccharification rate.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
