Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and more specifically, to a processing device, process and drink for tremella drink with frozen cell wall breaking and freshness preservation. Background Art

[0002] As a natural food material with both medicinal and edible properties, tremella is rich in polysaccharides, dietary fiber and trace elements, which can endow the drink with a unique colloidal texture and nutritional functions, meeting the trend of healthy consumption. It has now become one of the categories in the drink market with both taste and health preservation value.

[0003] When preparing tremella drink from dried tremella, the leaching rate of tremella polysaccharides is low. Moreover, the existing processes rely on pasteurization or ultra-high temperature instantaneous sterilization to extend the shelf life. However, high-temperature shear force will damage the tremella colloidal structure, cause the disintegration of micelles and lead to delamination and precipitation. In order to maintain stability, thickeners are forced to be added, which not only violates the clean label requirements but also loses nutritional components. Therefore, the industry has turned to low-temperature frozen cell wall breaking technology, which can avoid thermal damage and also improve the extraction rate of tremella polysaccharide components.

[0004] For traditional tremella freezing processing equipment, due to the use of centralized stacking freezing process, tremella is prone to adhesion during the freezing process, resulting in too thick material layer, uneven cold air penetration, temperature gradient difference during the freezing process, and finally damage to the tremella cell structure and overflow of intracellular colloidal substances, affecting the product shaping degree and nutritional component retention rate.

[0005] Therefore, this application proposes a processing device, process and drink for tremella drink with frozen cell wall breaking and freshness preservation to solve the above problems. Summary of the Invention

The output end of the driving motor is connected to the top end of the middle rotating shaft; Hydraulic rods II are installed on the left and right sides of the outer wall of the freezer. The telescopic ends of the two hydraulic rods II are respectively fixedly connected to the left and right sides of the bottom of the top cover.

[0011] In a new embodiment, the cold air assembly includes: A cold air generating source, installed in the upper part of the circular isolation cavity; A straight-through pipe, located in the circular isolation cavity, one end is connected to the exhaust end of the cold air generating source, and the other end extends to the outside of the bottom of the inner ring cylinder; There are three annular air pipes, which are equidistantly installed on the outer wall of the inner ring cylinder and are communicated with the straight-through pipe.

[0012] In a new embodiment, the cold air assembly further includes: three wall rings, which are equidistantly installed on the inner wall of the freezer, and three wall columns are installed on the inner ring walls of the wall rings; an inner extension column is slidably installed in the column groove of the wall column through a spring, and an L-shaped air connection pipe is installed in the inner extension column.

[0015] A processing technology for frozen wall-breaking and freshness-locking tremella drink, using the frozen wall-breaking and freshness-locking tremella drink processing equipment as described above, includes the following steps: S1. Raw material pretreatment: Select fresh tremella and wash it to remove impurities. S2. Step-by-step quick freezing: Lay the tremella in a stepped manner on the fan-shaped slotted plate, and snap the fan-shaped slotted plate onto the erection platforms of each layer. After sealing the freezer, start the cold air assembly, and send low-temperature air to the air flow arc nets at the top and bottom through the central pipe. The air flow arc net at the top forms a triangular cold air jet state to accelerate the formation of ice crystals on the surface of the tremella laid on the fan-shaped slotted plate. The air flow arc net at the bottom jets cold air obliquely downward to promote the freezing rate of the tremella laid on the lower fan-shaped slotted plate. S3. Dynamic scraping and pre-crushing: After freeze-drying, the tremella is driven by the driven central rotating shaft to drive the column disk and the elastic scraper to rotate, scrape the surface of the fan-shaped slotted plate, so that the freeze-dried tremella laid on it falls through the gap between adjacent fan-shaped slotted plates. The material collecting hopper collects the falling tremella, and through the ultrasonic vibration of the vibration assembly and the impact of the falling, the freeze-dried tremella is pre-crushed. S4. Freeze-drying and wall-breaking: The pre-crushed tremella enters the wall-breaking assembly through the cross-shaped opening, and after low-temperature wall-breaking and micronization by the wall-breaking assembly, tremella powder is obtained, and the obtained tremella powder is discharged to the outside for collection and utilization.

[0016] A tremella drink with frozen wall-breaking and freshness-locking function is prepared by rehydrating tremella powder obtained from the processing technology of the tremella drink with frozen wall-breaking and freshness-locking function and an edible solvent at a mass ratio of 1:50 - 80, and the particle size of the tremella powder is ≤80μm.

[0017] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows: 1. Through the modular design of the vertical column and the multi-layer erected ladder platform, a multi-level suspension layout of the fan-shaped inclined orifice plate is realized, greatly expanding the freezing area of tremella, avoiding material accumulation. The two-way counter-flushing cold air of the top air flow arc net forms a three-dimensional diagonal air curtain, improving the freezing rate of tremella. Then, the bottom inclined air outlet is used to quasi-cover the lower blind area, eliminating the freezing dead angle, reducing the damage of ice crystals to the cell structure, and comprehensively improving the freshness-locking effect of tremella.

[0018] 2. The cold air component conveys cold air to each layer of L-shaped air connecting pipes through the straight pipe and the annular air pipe, and the straight pipe can also maintain a low-temperature environment throughout the wall-breaking process for the wall-breaking bowl, as well as inhibit the heat transfer of the wall-breaking equipment, ensure the wall-breaking effect of tremella, inhibit the enzyme activity, and retain the heat-sensitive nutrients such as tremella polysaccharide to the greatest extent.

[0019] 3. The cold air component drives the sliding of the inner extension column by the like-pole repulsion of the electromagnet and the permanent magnet, so that the cold air outlet accurately docks with the socket of the fan-shaped inclined orifice plate, and the corresponding cold air spraying angle is adjusted according to the placement distribution of tremella, reducing the diffusion of ineffective cold air and improving the utilization efficiency of cold energy.

[0020] 4. By setting the central rotating shaft, column disk and elastic scraper, the rotating central rotating shaft drives the column disk and the elastic scraper to rotate, continuously scraping the surface of the fan-shaped inclined orifice plate, which can not only discharge the freeze-dried tremella on it through the gap between adjacent fan-shaped inclined orifice plates, but also quickly remove the residual freeze-dried tremella and ice frost, avoiding the blockage of holes.

[0021] 5. The frozen tremella is scraped by the elastic scraper, falls by gravity and collides with the hopper to achieve preliminary crushing. Under the guiding and gathering action of the hopper, it contacts the inclined column rod in the vibration component and undergoes impact vibration contact crushing, effectively performing wall-breaking pretreatment on the freeze-dried tremella.

[0022] 6. Using the same fresh tremella as the raw material, one kind of fresh tremella is dried at 50°C to obtain conventional dried tremella, and the other kind of freshness-locked tremella is prepared by the tremella processing technology with frozen wall-breaking and freshness-locking function. They are respectively added to 50 times of water and boiled for 3 hours. The extraction rates of tremella polysaccharide are 23.4% and 49.7% respectively. The polysaccharide extraction rate of the freshness-locked tremella is 2.1 times that of the dried tremella, which is much higher than that of the dried tremella. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] The embodiments of the present application provide a processing device, process and beverage for tremella drinks with freezing and cell wall breaking for freshness preservation, which solve the problems of material adhesion, uneven cold air distribution and cell structure damage and nutrient loss caused by the temperature gradient difference due to centralized stacking and freezing in traditional tremella processing. When in use, the device avoids material accumulation through three-dimensional hierarchical suspension and two-way air flow coverage, combines magnetic control cold air access to avoid the temperature gradient difference between the upper and lower layers, and uses ultrasonic vibration and low-temperature shearing and crushing technologies to efficiently retain nutrient components while suppressing cell damage, solving the problems of adhesion, uneven cold air and nutrient loss caused by stacking and freezing in the traditional process.

[0045] The technical solutions in the embodiments of the present application are as follows to solve the above technical problems.

[0046] Embodiment 1: Please refer to Figures 1 - 18, A processing device for tremella drink with freeze-breaking and freshness-locking function, including a freezer 1, further comprising: an inner ring cylinder 2, arranged on the inner wall of the freezer 1, and a circular isolation cavity 3 is formed between its outer inner wall and the outer wall of the freezer 1; a vertical column 4 is arranged in the middle of the inner ring cylinder 2, and three erection platforms 5 are equidistantly installed on the vertical column 4. Three hanging grooves 6 are equidistantly and circularly opened at the top of each erection platform 5. A sector-shaped inclined orifice plate 8 with a hanging block 7 installed at the bottom is clamped in each hanging groove 6. Socket openings 81 are opened on the outer sides of the sector-shaped inclined orifice plates 8; there are two groups of air flow arc nets 9, respectively installed at the top and bottom of the sector-shaped inclined orifice plates 8, and each air flow arc net 9 is composed of a plurality of single arc tubes 91; the exhaust port of the top single arc tube 91 is a two-way fan-shaped exhaust port 92, and a plurality of inclined sector-shaped air openings 93 are opened at the bottom of the bottom single arc tube 91; a central tube 10 is buried in the middle of the sector-shaped inclined orifice plate 8 and communicates with the two groups of air flow arc nets 9; a cold air assembly 11 is arranged in the circular isolation cavity 3 and supplies cold air to the air flow arc nets 9 through the central tube 10; a material collecting hopper 12 is installed at the lower side inside the inner ring cylinder 2, a vibration assembly 13 is installed at the lower part of the material collecting hopper 12, and a breaking wall assembly 14 communicated with the discharge port of the material collecting hopper 12 is installed at the bottom of the freezer 1.

[0047] In this embodiment, please refer to Figures 1 - 18 As shown, by setting the inner ring cylinder 2, the vertical column 4, the erection platforms 5, the hanging grooves 6, the hanging blocks 7 and the sector-shaped inclined orifice plates 8, using the three-layer erection platforms 5 on the vertical column 4, and clamping and installing the sector-shaped inclined orifice plates 8 through the action of the hanging grooves 6 and the hanging blocks 7, the tremella freezing placement method is changed, multi-level hanging of tremella is supported, the freezing area is expanded, material accumulation is avoided, the clamping design of the hanging grooves 6 and the hanging blocks 7 is convenient for disassembly, cleaning or replacement of the sector-shaped inclined orifice plates 8, adapting to different material specifications, improving the versatility of the equipment, and the three-layer erection platforms 5 support batch processing, the production capacity can be flexibly adjusted, suitable for small-batch customization and large-scale production requirements.

[0048] By setting two groups of air flow arc nets 9 at the top and bottom, firstly, for the top air flow arc net 9, on the one hand, it serves as the demarcation line for the tremella placement area of each step at the top of the sector-shaped inclined orifice plate 8, and on the other hand, using the two-way fan-shaped exhaust port 92 of the top single arc tube 91, the tremella placed in the area between two adjacent single arc tubes 91 can be subjected to counter-flush fan-shaped freezing treatment (forming a triangular air flow cover), accelerating the freezing rate. At the same time, for the bottom air flow arc net 9, using the inclined sector-shaped air openings 93 of the bottom single arc tube 91, more comprehensive air flow coverage is carried out on the corresponding tremella placement area on the lower sector-shaped inclined orifice plate 8, eliminating freezing dead corners, ensuring rapid and uniform cooling, reducing ice crystal formation, protecting the integrity of cell structure, and the cold air is distributed by the single arc tubes 91 at a preset angle, accurately covering the material area, avoiding ineffective diffusion and reducing energy consumption.

[0049] As Figure 16 shown, it should be noted that Figure 16The three arrows in it represent the air flow direction. The two triangular arrows at the top of the sector-shaped slotted plate 8 are the air flow directions of the air discharged from the two-way fan-shaped discharge ports 92 corresponding to the adjacent upper single-arc tubes 91; while the diagonal arrow at the bottom of the sector-shaped slotted plate 8 is the air flow direction of the air discharged from the diagonal sector-shaped air ports 93 of the lower single-arc tube 91.

[0050] By providing a socket 81 on the outer side of the sector-shaped slotted plate 8, the cold air assembly 11 can be docked with the sector-shaped slotted plate 8, so that the air flow arc net 9 connected to the central tube 10 in the sector-shaped slotted plate 8 can receive the cold air provided by the cold air assembly 11. This can not only fix the position of the sector-shaped slotted plate 8, but also reduce cold air escape and improve the utilization rate of cold energy.

[0051] It should be noted that due to the existence of an air flow coverage blind area at the top of the uppermost sector-shaped slotted plate 8 (because there is no upper sector-shaped slotted plate 8), a cooling air flow ring A can be added to the top wall of the capping cover 15 (as Figure 18 shown), which can always provide a downward continuous low-pressure cold air for the freezer 1. This air flow slowly penetrates evenly through the porous structure of the sector-shaped slotted plate 8, which not only avoids interfering with the operation of the air flow arc net 9, but also supplements the cold quantity in the top area, ensuring the temperature uniformity in the freezer 1 and eliminating the risk of local temperature rise.

[0052] Furthermore, please refer to Figure 4 and Figure 5 shown. A middle rotating shaft 41 rotates in the middle of the vertical column 4. Three column discs 42 are fixedly arranged at equal intervals on the middle rotating shaft 41. The three column discs 42 are all rotatably installed on the vertical column 4 at equal intervals. Three elastic scraping plates 43 that can scrape the surface of the sector-shaped slotted plate 8 are circumferentially installed at equal intervals on the outer edge of the column disc 42. By providing the middle rotating shaft 41, the column disc 42 and the elastic scraping plate 43, the rotating middle rotating shaft 41 drives the column disc 42 and the elastic scraping plate 43 to rotate, continuously scraping the surface of the sector-shaped slotted plate 8, so that the dried tremella on it is discharged through the gap between the adjacent sector-shaped slotted plates 8. At the same time, it can also be used as a cleaning structure for the surface of the sector-shaped slotted plate 8.

[0053] Please refer to Figure 1 and Figure 2As shown in the figure, the top of the freezer 1 is sealed with a capping cover 15. A vertical column 4 is fixedly installed on the top wall of the capping cover 15. A driving motor 16 is also installed on the top of the capping cover 15. The output end of the driving motor 16 is connected to the top end of the middle rotating shaft 41. On the left and right sides of the outer wall of the freezer 1, hydraulic rods II 17 are installed. The telescopic ends of the two hydraulic rods II 17 are respectively fixedly connected to the left and right sides of the bottom of the capping cover 15. By setting the capping cover 15, the driving motor 16 and the hydraulic rods II 17, the automatic sealed opening and closing of the freezer 1 is realized. The hydraulic rods II 17 drive the capping cover 15 to rise and fall, avoiding the cold air leakage and temperature fluctuation caused by manual opening of the cover. At the same time, the driving motor 16 on the capping cover 15 drives the middle rotating shaft 41 to drive the elastic scraper 43 to operate, discharging the freeze-dried tremella laid on the fan-shaped inclined orifice plate 8, which is convenient for the pre-treatment crushing and micronization and wall-breaking treatment of the freeze-dried tremella.

[0054] Please refer to Figure 6 and Figure 7 As shown in the figure, a cross-shaped opening 121 is installed at the bottom of the material collecting hopper 12. An outer sleeve column 122 is installed on the top of the cross-shaped opening 121. A hydraulic rod I 123 is installed inside the outer sleeve column 122. The telescopic end of the hydraulic rod I 123 is fixedly connected to the bottom of the vertical column 4. By setting the cross-shaped opening 121, the outer sleeve column 122 and the hydraulic rod I 123, the telescopic action of the hydraulic rod I 123 inside the outer sleeve column 122 drives the vertical column 4 connected to the top and the capping cover 15 connected to the vertical column 4 to rise and fall. Matching with the external hydraulic rods II 17, the horizontal and stable rise and fall of the capping cover 15 and the vertical column 4 can be realized.

[0055] Please refer to Figures 8 - 11 As shown in the figure, the cold air assembly 11 includes: a cold air generating source 1101, installed at the upper part of the annular isolation chamber 3; a straight-through pipe 1102, located inside the annular isolation chamber 3, one end of which is connected to the exhaust end of the cold air generating source 1101, and the other end extends to the outside of the bottom of the inner ring cylinder 2; three annular air pipes 1103, equidistantly installed on the outer wall of the inner ring cylinder 2 and connected to the straight-through pipe 1102. By setting the cold air generating source 1101, the straight-through pipe 1102 and the annular air pipes 1103, the cold air generated by the cold air generating source 1101 is transported to the annular air pipes 1103 through the straight-through pipe 1102, and then is branched to the corresponding layer through the three L-shaped connecting air pipes 1107 connected by hoses. Finally, the cold air is supplied to the central pipe 10 of the fan-shaped inclined orifice plate 8 of this layer through the L-shaped connecting air pipe 1107, realizing the directional output of cold air.

[0056] Further, the cold air assembly 11 further includes: three wall rings 1104, which are equidistantly installed on the inner wall of the freezer 1, and three wall columns 1105 are installed on the inner ring walls of the wall rings 1104; a sliding inner extension column 1106 is installed in the column groove of the wall column 1105 through a spring, an L-shaped air connecting pipe 1107 is installed in the inner extension column 1106, one end of the L-shaped air connecting pipe 1107 is connected to the ring air pipe 1103 through a hose, and the inner extension column 1106 is slidably connected to the inner ring cylinder 2; a permanent magnet 1108 is installed on the outer side of the wall column 1105; an electromagnet 1109 is installed on the outer side of the inner end of the wall column 1105, and the permanent magnet 1108 and the electromagnet 1109 are arranged on the same horizontal line.

[0057] By setting the wall ring 1104, the wall column 1105, the inner extension column 1106, the L-shaped air connecting pipe 1107, the permanent magnet 1108 and the electromagnet 1109, the electromagnet 1109 is activated to generate a magnetic field with the same pole as the permanent magnet 1108 (for example, the electromagnet 1109 is set as the N pole and the permanent magnet 1108 is fixed as the N pole), triggering the repulsive effect of like magnetic poles, driving the inner extension column 1106 connected to the permanent magnet 1108 to slide in the wall column 1105 and slide inward into the inner ring cylinder 2 until it is accurately docked with the socket 81 on the positioned sector-shaped inclined orifice plate 8. After insertion, the L-shaped air connecting pipe 1107 stably supplies cold air into the sector-shaped inclined orifice plate 8 through the central pipe 10 to achieve directional cold supply. On the contrary, when the electromagnet 1109 does not generate magnetism, it is also convenient to take out the sector-shaped inclined orifice plate 8.

[0058] Please refer to Figure 6 and Figure 7 As shown in, the vibration assembly 13 includes: an ultrasonic generator 1301 installed on the upper part of the inner wall of the inner ring cylinder 2; transducers 1302 are equidistantly and annularly installed on the lower part of the outer wall of the material collecting hopper 12, and the transducers 1302 are connected to the ultrasonic generator 1301 through wires; one end of an inclined column rod 1303 is connected to the transducer 1302, and the other end penetrates through the outer wall of the material collecting hopper 12 and is equidistantly and annularly distributed inside the material collecting hopper 12.

[0059] By setting the ultrasonic generator 1301, the transducers 1302 and the inclined column rod 1303, ultrasonic waves are transmitted to the inclined column rod 1303 through the transducers 1302 to form a vibrating discharge port at the discharge port of the material collecting hopper 12. The frozen tremella is discharged and dropped by the action of the elastic scraper 43. On the one hand, the frozen tremella falls by gravity and collides with the inner wall of the material collecting hopper 12 to achieve preliminary crushing. On the other hand, under the guiding and aggregating action of the material collecting hopper 12, the continuously falling freeze-dried tremella will also contact the inclined column rods 1303 arranged at the discharge port for impact vibration and contact crushing. At the same time, the inclined column rods 1303 are equidistantly and annularly distributed, so that the vibration waves evenly cover the inner wall of the material collecting hopper 12, effectively eliminating the phenomenon of material adhesion or local accumulation, ensuring that the frozen tremella is continuously and stably transported to the wall breaking assembly 14, and significantly reducing the risk of blockage.

[0060] Please refer to Figure 12 As shown, the cell wall breaking assembly 14 includes: a heat preservation cylinder 1401 installed at the bottom of the freezer 1; a cell wall breaking bowl 1402 installed in the middle of the bottom wall of the heat preservation cylinder 1401, and a heat conduction layer is provided on the outer wall of the cell wall breaking bowl 1402; a servo motor 1403 is installed at the bottom of the heat preservation cylinder 1401, and a cell wall breaking blade paddle 1404 is fixedly installed at the output end of the servo motor 1403. The cell wall breaking blade paddle 1404 is rotatably installed in the cell wall breaking bowl 1402, and the top end of the cell wall breaking blade paddle 1404 is rotatably installed at the bottom of the cross-shaped opening 121.

[0061] By setting the heat preservation cylinder 1401, the cell wall breaking bowl 1402, the servo motor 1403 and the cell wall breaking blade paddle 1404, the servo motor 1403 is used to drive the cell wall breaking blade paddle 1404 to rotate at a high speed, and the frozen tremella in the cell wall breaking bowl 1402 is subjected to strong shearing and crushing. The heat preservation cylinder 1401 provides a low-temperature environment for the cell wall breaking bowl 1402 (this low-temperature environment is transmitted from the cold air generating source 1101 and the straight-through pipe 1102 in the cold air assembly 11 to the inner wall of the heat preservation cylinder 1401 and the outer wall of the cell wall breaking bowl 1402), effectively inhibiting the heat accumulation and transmission at the connection between the servo motor 1403 and the cell wall breaking blade paddle 1404, avoiding the destruction of the characteristics of freeze-dried tremella due to temperature rise. This low-temperature collaborative crushing system can improve the cell wall breaking rate of tremella and retain its heat-sensitive nutrients such as polysaccharides to the greatest extent.

[0062] Example 2: Please refer to Figures 1 - 18 This application example provides a processing technology for frozen cell wall breaking and freshness locking of tremella drinks. Using the processing equipment of Example 1, it includes the following steps: S1. Raw material pretreatment: Select fresh tremella and wash away impurities; S2. Step-by-step quick freezing: Lay the tremella step by step on the fan-shaped inclined hole plate 8, and snap the fan-shaped inclined hole plate 8 onto the erection ladder platforms 5 of each layer. After sealing the freezer 1, start the cold air assembly 11, and send low-temperature air flow to the air flow arc nets 9 at the top and bottom through the central pipe 10. The air flow arc net 9 at the top forms a triangular cold air jet state to accelerate the formation of ice crystals on the surface of the tremella laid on the fan-shaped inclined hole plate 8. The air flow arc net 9 at the bottom sprays cold air obliquely downward to promote the freezing rate of the tremella laid on the lower fan-shaped inclined hole plate 8; S3. Dynamic scraping and pre-crushing: After freeze-drying, the tremella is driven by the driven middle rotating shaft 41 to drive the column disk 42 and the elastic scraper 43 to rotate, scrape the surface of the fan-shaped inclined hole plate 8, so that the freeze-dried tremella laid on it falls through the gaps between adjacent fan-shaped inclined hole plates 8. The material collecting hopper 12 collects the falling tremella, and through the ultrasonic vibration of the vibration assembly 13 and the impact of the falling, the freeze-dried tremella is pre-crushed; S4. Freeze-drying and cell wall breaking: The pre-crushed tremella enters the cell wall breaking component 14 through the cross-shaped opening 121, and tremella powder is obtained through the low-temperature cell wall breaking and micronization of the cell wall breaking component 14, and the obtained tremella powder is discharged to the outside for collection and utilization.

[0063] Meanwhile, to further analyze the polysaccharide extraction rate of the freshness-locked tremella prepared by the tremella processing technology of freeze-drying cell wall breaking and freshness locking, the following comparative experiments were carried out: Using the same fresh tremella as the raw material, one kind dried the fresh tremella at 50 °C to obtain conventional dried tremella, and the other kind prepared freshness-locked tremella by using the tremella processing technology of freeze-drying cell wall breaking and freshness locking. They were respectively added to 50 times the amount of water and boiled for extraction for 3 hours to conduct a comparative experiment on the polysaccharide extraction rate. The specific data are as Figure 19 shown.

[0064] In summary, according to Figure 19 the data, under the processing technologies of drying tremella at 50 °C and freeze-drying cell wall breaking and freshness locking, the polysaccharide extraction rates are 23.4% and 49.7% respectively. The polysaccharide extraction rate of the freshness-locked tremella is 2.1 times that of the dried tremella, which is much higher than that of the dried tremella. Therefore, the freeze-drying cell wall breaking technology can significantly improve the polysaccharide dissolution rate by destroying the cell wall structure with ice crystals.
