Description

Technical Field

[0001] This invention relates to the field of dairy product mixing technology, specifically to a mixing equipment and method for dairy product production. Background Technology

[0002] Dairy products are foods made primarily from cow's or goat's milk and their processed products, with or without added vitamins and other auxiliary ingredients; they are also known as cream products. They mainly include seven categories: liquid milk, milk powder, condensed milk, milk fat, cheese, and dairy ice cream. Milk fat products encompass cream, heavy cream, and other similar products, and must meet standards such as a fat content ≥80% and a total bacterial count ≤10^5 CFU / g. Production processes include pasteurization (heating at 60℃ to sterilize and preserve flavor) and ultra-high temperature (UHT) sterilization (sterilization at 135-150℃ for 1-4 seconds, extending shelf life). During the production of dairy products, mixing equipment is required to combine the materials.

[0003] Chinese patent application CN117085531A discloses a multifunctional powder-liquid mixing high-shear dispersion emulsifier. This multifunctional powder-liquid mixing high-shear dispersion emulsifier includes a base, with a motor and an emulsifying head mounted on the top of the base. The output shaft of the motor is connected to the input end of a coupling, and the output end of the coupling is connected to a drive shaft. One end of the drive shaft extends into the emulsifying head. The emulsifying head includes a shearing chamber, a liquid inlet chamber, and a mixing chamber arranged sequentially. The shearing chamber contains a shearing structure for dispersing and shearing the powder. The drive shaft is connected to the shearing structure and drives the shearing structure to rotate. The liquid inlet chamber has a through-hole at its top and a flow guide structure inside for guiding liquid materials into the mixing chamber. The mixing chamber contains a mixing structure for mixing and emulsifying the powder and liquid materials.

[0004] However, the structural design of the aforementioned technologies, while enabling the material to collide with the valve disc and impeller during the mixing process and disperse the material, relies solely on the impeller's drive for mixing after the material enters the cavity. This results in relatively small disturbances during mixing within the cavity, which in turn limits the dispersion effect of the material within the cavity, thereby affecting the mixing effect and efficiency.

[0005] Therefore, a mixing equipment and method for dairy product production is proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides a mixing equipment and method for dairy product production, aiming to solve the problem in related technologies where the disturbance during the material mixing process is small, thus affecting the mixing effect and mixing efficiency.

[0007] The mixing equipment for dairy production of the present invention includes a tank and a feeding mechanism connected to the tank. A circulation mechanism is connected to the end of the tank, and the material in the tank can enter the circulation mechanism. A mixing mechanism is rotatably connected inside the circulation mechanism.

[0008] The mixing mechanism includes a filter assembly disposed in the circulation mechanism, a mixing assembly rotatably connected to the filter assembly, a disturbance assembly disposed on the mixing assembly, and a spiral shaft mounted on the disturbance assembly. The circulation mechanism can drive the mixing assembly to rotate in the filter assembly.

[0009] The filter assembly includes a fixed cylinder disposed in the circulation mechanism and multiple limiting plates installed inside the fixed cylinder. The limiting plates are arc-shaped, and filter holes are opened on the outer side of the fixed cylinder. The mixing assembly is rotatably disposed in the fixed cylinder.

[0010] The disturbance component includes a guide shaft disposed on the mixing component, a sliding sleeve elastically slidably connected to the guide shaft, and a plurality of disturbance plates mounted on the outer side of the end of the sliding sleeve. The disturbance plates are disposed along the tangential direction of the sliding sleeve and can contact the limiting plate to push the disturbance plates to reciprocate along the guide shaft.

[0011] When mixing materials, liquid and powdered materials are first added to the inside of the tank to premix them. After mixing, the materials enter the circulation mechanism from the bottom of the tank. When the materials enter the circulation mechanism, the circulation mechanism drives the mixing component to rotate in the fixed cylinder. At the same time, the mixing component drives multiple disturbance plates to rotate synchronously in the fixed cylinder through the guide shaft. During the rotation, the disturbance plates gradually come into contact with the limiting plate. When the disturbance plates come into contact with the limiting plate, under the action of the limiting plate, the disturbance plates can reciprocate along the guide shaft, thereby dividing the materials in the fixed cylinder, making the materials more dispersed, and increasing the disturbance of the materials in the fixed cylinder.

[0012] Preferably, the mixing assembly includes a rotating plate, a connecting shaft, and multiple blades. The rotating plate is rotatably disposed inside one side of the fixed cylinder. The connecting shaft is installed at one end of the rotating plate and is connected to the circulation mechanism. The multiple blades are arranged in a ring array at the other end of the rotating plate, and the guide shaft is installed at the middle of the other end of the rotating plate.

[0013] The circulation mechanism drives the rotating plate to rotate via the connecting shaft. At the same time, multiple blades on the rotating plate rotate synchronously with the rotating plate. When the material is fed into the circulation mechanism, it will immediately collide with these rotating blades. Meanwhile, the disturbance plate can divide the material entering the circulation mechanism, preventing the material from accumulating or clumping, so that the material can be more evenly and fully dispersed, thereby significantly improving the mixing effect of the material in the circulation mechanism.

[0014] Preferably, the plurality of blades are located on the outside of the guide shaft, the helical shaft is mounted at one end of the guide shaft, and each of the disturbance plates is located between two adjacent blades.

[0015] When the baffle plate reciprocates, the material between the two blades flows along the edge of the baffle plate. As the material flows along the edge of the baffle plate, the continuous reciprocating motion of the baffle plate and the guiding effect of the edge on the material enable the material to collide more fully with the blades, thereby improving the efficiency and effectiveness of the entire material mixing process.

[0016] Preferably, the disturbance assembly further includes a retaining ring and a spring, the retaining ring being mounted on the outside of the guide shaft and located inside the sliding sleeve, and the spring being sleeved on the outside of the guide shaft and mounted between the retaining ring and the inner wall of the sliding sleeve.

[0017] When the disturbance plate begins to move along the guide shaft under the action of the limiting plate, the disturbance plate can compress the spring through the sliding sleeve. When the disturbance plate disengages from the limiting plate, the spring returns to its original position. At this time, the force of the spring returning to its original position can drive the disturbance plate on the sliding sleeve to return to its original position, so that the disturbance plate can continue to contact the subsequent limiting plate, thereby enabling the disturbance plate to reciprocate.

[0018] Preferably, the limiting plate has a triangular cross-section, and the disturbance plate has a hexagonal cross-section.

[0019] Preferably, the filter holes are arc-shaped, and there are multiple filter holes arranged in a ring array on the outside of the fixed cylinder.

[0020] Preferably, the circulation mechanism includes a drive component, a protective cover, a circulation pipe, and a return pipe. The protective cover is installed at one end of the drive component, the fixed cylinder is installed on one side of the inner wall of the protective cover, the connecting shaft is connected to the drive component, one end of the circulation pipe is installed at one end of the protective cover, and the other end of the circulation pipe is connected to the end of the tank. One end of the return pipe is installed at the bottom of the protective cover, and the other end of the return pipe is connected to the tank.

[0021] After the material flows out of the tank, it enters the protective cover through the circulation pipe for mixing. After the material is mixed in the protective cover, it passes through the filter holes on the fixed cylinder and enters the protective cover. At this time, the material in the protective cover flows back to the tank through the return pipe.

[0022] Preferably, a discharge pipe is installed at the bottom of the tank, one end of the circulation pipe is connected to one side of the discharge pipe, and a feed pipe is installed at the bottom of one side of the tank, which is connected to the feeding mechanism.

[0023] Preferably, the feeding mechanism includes a hopper and a discharge pipe, one end of the discharge pipe is installed at the bottom of the hopper, and the other end of the discharge pipe is connected to the feed pipe.

[0024] The mixing method for dairy product production of the present invention, utilizing the above-mentioned mixing equipment for dairy product production, includes the following steps:

[0025] S1: Convey liquid and powdered materials into the tank;

[0026] S2: After the materials are mixed in the tank, they enter the protective cover through the circulation pipe to continue mixing;

[0027] S3: The driving component drives the rotating plate, guide shaft and spiral shaft to rotate synchronously through the connecting shaft. At the same time, the rotating plate drives the blades to rotate to mix the material. During the rotation of the rotating plate, under the action of the limiting plate, the disturbance plate moves back and forth along the guide shaft, causing the material to be diverted along the edge of the disturbance plate and collide with the blades, making the material more dispersed.

[0028] S4: After the materials are mixed in the protective cover, they are returned to the tank through the return pipe for further mixing.

[0029] During the mixing process, liquid and powdered materials are conveyed into the tank. After mixing in the tank, the materials enter the protective cover through the circulation pipe. At this time, the drive unit drives the rotating plate to rotate via the connecting shaft. The rotating plate drives the blades to rotate and mix the materials. Simultaneously, the rotating plate drives the disturbance plate to rotate synchronously via the guide shaft. Under the action of the limiting plate, the disturbance plate can reciprocate along the guide shaft. During the reciprocating movement of the disturbance plate, the material between the two blades can be diverted along the edge of the disturbance plate, allowing the material to better contact and collide with the blades, thereby making the material more dispersed. At the same time, the movement of the disturbance plate can also increase the disturbance of the material in the protective cover, thereby making the material better mixed.

[0030] The beneficial effects of the present invention, achieved by adopting the above technical solution, are as follows: When mixing materials, liquid materials and powdered materials are added to the inside of the tank to premix the two materials in the tank. The mixed materials enter the circulation mechanism from the bottom of the tank. When the materials enter the circulation mechanism, the circulation mechanism drives the mixing component to rotate in the fixed cylinder. At the same time, the mixing component drives multiple disturbance plates to rotate synchronously in the fixed cylinder through the guide shaft. During the rotation, the disturbance plates can gradually contact the limiting plate. When the disturbance plates contact the limiting plate, under the action of the limiting plate, the disturbance plates can reciprocate along the guide shaft, thereby dividing the materials in the fixed cylinder, making the materials more dispersed, and increasing the disturbance of the materials in the fixed cylinder, thereby improving the mixing efficiency and mixing effect of the materials.

[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] like Figures 1 to 9 As shown, the mixing equipment for dairy product production of the present invention includes a mixing tank 10, a circulation mechanism 20, a feeding mechanism 30, and a mixing mechanism 40. The mixing tank 10 has two inlet ends on its outer side, two outlet ends at its bottom, and a liquid inlet end at its top. The outlet end of the feeding mechanism 30 is connected to one of the inlet ends of the mixing tank 10. The inlet end of the circulation mechanism 20 is connected to one of the outlet ends of the mixing tank 10, and the outlet end of the circulation mechanism 20 is connected to the other inlet end of the mixing tank 10. The mixing mechanism 40 is rotatably connected inside the circulation mechanism 20 to mix the materials.

[0047] When mixing materials, liquid materials are fed into the mixing tank 10 through the inlet. Then, the feeding mechanism 30 is activated, which transports powdered materials into the mixing tank 10. After entering the mixing tank 10, the materials undergo preliminary mixing, allowing different materials to initially disperse and blend within the tank. The pre-mixed materials are discharged from the bottom of the mixing tank 10 and enter the circulation mechanism 20. As the materials flow through the circulation mechanism 20, they pass through the mixing mechanism 40 located within it. The mixing mechanism 40 further deepens the mixing of the materials as they pass through the mixing mechanism 40. The mixed materials are then returned to the mixing tank 10 by the circulation mechanism 20 until the mixing process is complete.

[0048] like Figures 1 to 2 As shown, the mixing tank 10 includes a tank body 11, a discharge pipe 12, a feed pipe 13, and support legs 14. The lower half of the tank body 11 is conical. A liquid inlet pipe is installed on one side of the top of the tank body 11, the discharge pipe 12 is installed at the bottom of the tank body 11, and the discharge end of the circulation mechanism 20 is installed in the middle of one side of the tank body 11. A heating component (not shown in the figure) is provided on the tank body 11. In this embodiment, the heating component on the tank body 11 is an electric heating wire to heat the material in the tank body 11. In the initial state, the bottom end of the discharge pipe 12 is closed, and the feed end of the circulation mechanism 20 is located on one side of the discharge pipe 12 so that the material can enter the circulation mechanism 20 through the discharge pipe 12. One end of the feed pipe 13 is installed at the bottom of one side of the tank body 11, and the other end of the feed pipe 13 is installed on the feeding mechanism 30. There are multiple support legs 14, which are arranged in a circular array at the bottom of the tank body 11.

[0049] When mixing materials, liquid materials are transported into tank 11 through the inlet pipe, and then powdered materials are transported into tank 11 through inlet pipe 13 by feeding mechanism 30 and mixed with the liquid materials. The mixed materials in tank 11 enter outlet pipe 12, and then the materials in outlet pipe 12 enter circulation mechanism 20 from one side of outlet pipe 12. At this time, they are mixed again by mixing mechanism 40, and the mixed materials enter tank 11 again through the outlet end of mixing mechanism 40 for mixing and heating.

[0050] like Figures 1 to 4 As shown, the circulation mechanism 20 includes a drive component 21, a support plate 22, a support frame 23, a protective cover 24, a circulation pipe 25, and a return pipe 26.

[0051] The drive unit 21 includes a mounting cover and a motor. The motor is installed inside the mounting cover and is connected to the mixing mechanism 40 to drive the mixing mechanism 40. The support plate 22 is arc-shaped. The mounting cover of the drive unit 21 is installed inside the support plate 22, and the support frame 23 is installed outside the support plate 22. The protective cover 24 is installed at one end of the mounting cover of the drive unit 21, and the mixing mechanism 40 is located inside the protective cover 24. One end of the circulation pipe 25 is installed at one end of the protective cover 24, and the other end of the circulation pipe 25 is installed on one side of the discharge pipe 12 and connected to the discharge pipe 12. One end of the return pipe 26 is installed at the bottom of the protective cover 24, and the other end of the return pipe 26 is installed on one side of the tank body 11 and connected to the tank body 11.

[0052] During the mixing process, the material in tank 11 flows through discharge pipe 12 into protective cover 24, which is connected to discharge pipe 12. Protective cover 24 is used to ensure the safety and cleanliness of the operating environment. Simultaneously, the motor in drive unit 21 drives mixing mechanism 40 to rotate, thoroughly and evenly mixing the material entering protective cover 24. After thorough mixing by mixing mechanism 40, the material flows into return pipe 26 located at the bottom of protective cover 24, returning to tank 11. The material returning to tank 11 is mixed again, and the heating element on tank 11 continues to heat the returned material to further improve the mixing effect.

[0053] like Figures 2 to 5 As shown, the mixing mechanism 40 includes a filter assembly 41, a mixing assembly 42, a disturbance assembly 43, and a spiral shaft 44. The filter assembly 41 is mounted on one side of the inner wall of the protective cover 24. The mixing assembly 42 is rotatably disposed inside the filter assembly 41 and connected to the motor in the drive component 21. The disturbance assembly 43 is disposed on the mixing assembly 42. One end of the spiral shaft 44 is mounted on one end of the disturbance assembly 43, and the other end of the spiral shaft 44 extends into the interior of the circulation pipe 25.

[0054] As the material enters the protective cover 24 through the circulation pipe 25, the motor in the drive component 21 drives the agitation component 43 and the screw shaft 44 to rotate via the mixing component 42. At this time, the screw shaft 44 accelerates the material's entry into the protective cover 24. During the rotation of the mixing component 42, the material collides with it, thus dispersing the powder. Simultaneously, the agitation component 43 slides back and forth within the mixing component 42, increasing the agitation of the material within the protective cover 24, thereby enabling better mixing. The material mixed by the mixing component 42 passes through the filter component 41 and enters the return pipe 26, returning to the tank 11 along the return pipe 26.

[0055] like Figures 4 to 6 As shown, the filter assembly 41 includes a fixed cylinder 411 and a limiting plate 412. One end of the fixed cylinder 411 is installed on one side of the inner wall of the protective cover 24. There is a space for material to pass through between the outer wall of the fixed cylinder 411 and the inner wall of the protective cover 24. The mixing assembly 42 and the agitation assembly 43 are both located inside the fixed cylinder 411. Multiple filter holes 413 are provided on the outer side of the fixed cylinder 411. The filter holes 413 are arc-shaped and are arranged in a ring array on the fixed cylinder 411 with the axis of the fixed cylinder 411 as the center. The limiting plate 412 is arc-shaped and has a triangular cross-section. There are multiple limiting plates 412, which are arranged in a ring array on the inner wall of the fixed cylinder 411. The agitation assembly 43 can contact the limiting plate 412.

[0056] During the mixing process, the motor in the drive unit 21 drives the mixing component 42 and the agitation component 43 to rotate within the fixed cylinder 411. As the mixing component 42 rotates, it disperses the material, ensuring uniform mixing. During rotation, the agitation component 43 also contacts the limiting plate 412. Under the action of the limiting plate 412, the agitation component 43 slides back and forth along the axis of the mixing component 42 within the fixed cylinder 411, agitating the material within the protective cover 24 and further enhancing the uniformity of the mixture. After mixing within the protective cover 24, the material passes through the filter holes 413, through the fixed cylinder 411, and through the return pipe 26 into the tank 11.

[0057] like Figures 3 to 7As shown, the mixing component 42 includes a rotating plate 421, blades 422, and a connecting shaft 423. The rotating plate 421 is rotatably connected to one side of the interior of the fixed cylinder 411. One end of the connecting shaft 423 is mounted on one end of the rotating plate 421, and the other end of the connecting shaft 423 passes through the protective cover 24 and is connected to the drive shaft of the motor in the drive component 21. The blades 422 are mounted on the other end of the rotating plate 421. There are multiple blades 422, which are arranged in a circular array around the axis of the rotating plate 421, and the blades 422 are arc-shaped.

[0058] The motor in the drive unit 21 can drive the rotating plate 421 to rotate in the fixed cylinder 411 through the connecting shaft 423. At this time, the rotating plate 421 drives the blade 422 to rotate, so that the inside of the protective cover 24 generates negative pressure, so as to draw the material from the tank 11 into the protective cover 24. The material entering the protective cover 24 collides with the blade 422, disperses the material, and mixes the material.

[0059] like Figures 5 to 9 As shown, the disturbance assembly 43 includes a sliding sleeve 431, a disturbance plate 432, a guide shaft 433, a retaining ring 434, and a spring 435. One end of the guide shaft 433 is mounted on one end of the rotating plate 421, and the helical shaft 44 is mounted on the other end of the guide shaft 433. The sliding sleeve 431 is slidably connected to the outside of the guide shaft 433. The retaining ring 434 is mounted on the outside of the guide shaft 433 and located inside the sliding sleeve 431. The spring 435 is sleeved on the outside of the guide shaft 433. One end of the spring 435 is mounted on one end of the retaining ring 434, and the other end of the spring 435 is mounted on one end of the inner wall of the sliding sleeve 431. An elastic rubber pad is provided between the sliding sleeve 431 and the rotating plate 421 to cushion the sliding sleeve 431.

[0060] A disturbance plate 432 is installed on the outer side of one end of the sliding sleeve 431 along the tangential direction of the sliding sleeve 431, with the end of the disturbance plate 432 inclined. Multiple disturbance plates 432 are arranged in a circular array on the sliding sleeve 431 with the axis of the sliding sleeve 431 as the center. The number of disturbance plates 432 is equal to the number of blades 422, and each disturbance plate 432 is located between two adjacent blades 422. The cross-sectional shape of the disturbance plate 432 is hexagonal to divide the material between two blades 422, increasing the disturbance of the material.

[0061] During the rotation of the rotating plate 421 via the connecting shaft 423 driven by the motor in the drive unit 21, the rotating plate 421 drives the disturbance plate 432 on the sliding sleeve 431 to rotate via the guide shaft 433. As the disturbance plate 432 rotates, it gradually comes into contact with the limiting plate 412. At this time, under the action of the limiting plate 412, the disturbance plate 432 moves along the guide shaft 433 during rotation. Simultaneously, the disturbance plate 432 compresses the spring 435 via the sliding sleeve 431, causing the sliding sleeve 431 to slide on the guide shaft 433. When the disturbance plate 432 disengages from the limiting plate 412, the spring 435 resets. The force of the spring 435 resets the disturbance plate 432 on the sliding sleeve 431, allowing the disturbance plate 432 to continue contacting the next limiting plate 412. This enables the disturbance plate 432 to reciprocate along the guide shaft 433, continuously disturbing the material in the fixed cylinder 411.

[0062] During the movement of the disturbance plate 432, the material entering the fixed cylinder 411 can be dispersed to both sides along the edge of the disturbance plate 432, so that the material can better collide with the blade 422 and the material can be more dispersed.

[0063] like Figures 1 to 2 As shown, the feeding mechanism 30 includes a hopper 31, a discharge pipe 32, and support legs 33. The top end of the discharge pipe 32 is installed at the bottom end of the hopper 31, and the bottom end of the discharge pipe 32 is installed at one end of the feed pipe 13. There are four support legs 33, which are installed at the four corners of the bottom of the hopper 31.

[0064] When mixing materials, the silo 31 conveys the powdered material to the feed pipe 13 through the discharge pipe 32. At this time, the material enters the tank 11 along the feed pipe 13, so that the powdered material is mixed with the liquid material in the tank 11.

[0065] Working principle: When mixing materials, liquid materials are first transported into tank 11 through the inlet pipe. Then, the feeding mechanism 30 transports powdered materials into tank 11 through the feed pipe 13 to mix with the liquid materials. During the process of the materials entering tank 11, the motor in the drive unit 21 drives the rotating plate 421 to rotate in the fixed cylinder 411 through the connecting shaft 423. At this time, the rotating plate 421 drives the blades 422 to rotate synchronously, which can generate negative pressure inside the protective cover 24 to extract the materials from tank 11. The materials mixed in tank 11 enter the discharge pipe 12. At this time, under the action of negative pressure, the materials in the discharge pipe 12 can enter the protective cover 24 from one side of the discharge pipe 12 through the circulation pipe 25 for mixing.

[0066] When the material enters the protective cover 24, it collides with the blades 422 to break up large clumps of material and improve mixing. Simultaneously, the rotating plate 421 drives the guide shaft 433 to rotate. During rotation, the guide shaft 433 drives multiple disturbance plates 432 to rotate synchronously via the sliding sleeve 431. As the disturbance plates 432 rotate, they gradually come into contact with the limiting plate 412. When in contact with the limiting plate 412, the limiting plate 412 causes the disturbance plates 432 to move along the guide shaft 433 during rotation. Simultaneously, the sliding sleeve 431 compresses the spring 435, causing the sliding sleeve 431 to slide on the guide shaft 433. When the disturbance plate 432 disengages from the limiting plate 412, the spring 435 resets. At this time, the force of the spring 435 resetting drives the disturbance plate 432 on the sliding sleeve 431 to reset, so that the disturbance plate 432 continues to contact the next limiting plate 412, thereby enabling the disturbance plate 432 to reciprocate along the guide shaft 433 to continuously disturb the material in the fixed cylinder 411.

[0067] During the movement of the disturbance plate 432, the material entering the fixed cylinder 411 can be dispersed to both sides along the edge of the disturbance plate 432, while further breaking up large pieces or clumps of material, so that the material can better collide with the blade 422, thereby improving the mixing efficiency and mixing effect of the material.

[0068] The mixing method for dairy product production of the present invention, performed using the above-mentioned mixing equipment for dairy product production, includes the following steps:

[0069] S1: Liquid material is transported to tank 11 through the inlet pipe on tank 11, and powdered material is transported to inlet pipe 13 through discharge pipe 32 through hopper 31, and then transported to tank 11 through inlet pipe 13. At the same time, drive component 21 drives blade 422 on rotating plate 421 to rotate through connecting shaft 423 to generate negative pressure, so that circulation pipe 25 can draw material from outlet pipe 12 of tank 11.

[0070] S2: When the material enters the tank 11, the material is first initially mixed in the tank 11. After the material is mixed in the tank 11, the material in the tank 11 enters the protective cover 24 through the circulation pipe 25 under the action of negative pressure to continue mixing.

[0071] S3: When the material enters the protective cover 24, the driving component 21 drives the rotating plate 421, the guide shaft 433 and the spiral shaft 44 to rotate synchronously through the connecting shaft 423. At the same time, the rotating plate 421 drives the blade 422 to rotate, so that the material collides with the blade 422 and disperses to mix the material.

[0072] During the rotation of the rotating plate 421, under the action of the limiting plate 412 and the spring 435, the disturbance plate 432 can reciprocate along the guide shaft 433. During the reciprocating movement of the disturbance plate 432, the material can be diverted along the edge of the disturbance plate 432 and collide with the blades 422 on both sides of the disturbance plate 432, so that the material can better contact the blades 422 and make the material more dispersed.
