Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a water-cooled conveying device and method for plant protein powder. Background Art

[0002] Plant protein powder is a common food and a nutritional supplement mainly composed of protein, usually extracted from foods such as whey, soybeans, peas, and rice. In the production process of plant protein powder, the protein solution is usually atomized into tiny droplets and quickly dried by high-temperature hot air (150 - 200 °C) to form powder. After the protein powder is dried, its temperature is relatively high and it is easy to come into contact with the moisture in the environment, resulting in the formation of surface condensate and causing moisture absorption and caking. Usually, after drying, a water-cooled conveying device is used to convey the protein powder to the equipment of the next process and cool the protein powder during the conveying process.

[0003] For example, the "water-cooled spiral cooler" with the publication number "CN218781483U" mainly forms a water-cooled cavity between the water-cooled jacket outside the conveying cylinder and the conveying cylinder, and cold water is introduced into the inside of the conveying cylinder through the water inlet flange pipe and discharged from the water outlet flange pipe. The circulating direction of the cold water is opposite to the material conveying direction, so as to achieve the effect of cooling the material. In this way, the material can be cooled from both inside and outside at the same time, thereby improving the cooling effect on the material.

[0004] When introducing cold water, in order to improve the cooling efficiency, the water temperature may be set relatively low. The temperature of the conveyed plant protein powder is relatively high and it will contain high-temperature air entering the inside of the conveying device. When contacting the low-temperature surface, the temperature of the material or the equipment surface may quickly drop below the dew point temperature of the surrounding air, easily forming condensate, resulting in the bonding of the powder material and affecting the conveying efficiency. Moreover, the bonded powder material will affect the heat exchange effect of the heat exchange surface, and then affect the heat exchange efficiency. In the actual transportation process, many screw conveyors are arranged horizontally or slightly inclined. When conveying this kind of powder material such as plant protein powder, it is easy to accumulate at the bottom position inside the screw conveyor. The accumulation of the powder material easily causes the powder material inside the accumulation area to be difficult to exchange heat with the outside, thereby affecting the heat exchange effect and then easily affecting the cooling effect of the powder material. Summary of the Invention

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0042] Embodiment 1: Please refer to Figures 1 to 11 , the present invention provides a technical solution: a plant protein powder water cooling and conveying device, including a conveyor cylinder body 1, a screw shaft 2 rotates inside the conveyor cylinder body 1, the outer wall of the screw shaft 2 is fixedly connected with screw blades, and when the screw shaft 2 rotates, it conveys the powder material. A cooling cavity 3 for introducing cold water to cool the inside of the conveyor cylinder body 1 is opened inside the conveyor cylinder body 1. The water cooling and conveying device further includes a dispersion assembly 4 arranged inside the conveyor cylinder body 1. The dispersion assembly 4 is used to disperse the powder material inside the conveyor cylinder body 1. The dispersion assembly 4 includes a scraping frame 41 fixed on the outer wall of the screw shaft 2, and a plurality of scraping frames 41 are configured. The scraping frame 41 is used to stir and disperse the powder material accumulated on the inner side of the conveyor cylinder body 1. A scraping strip 42 is fixed on the outer wall of the scraping frame 41. A motor for driving the screw shaft 2 to rotate is fixed on the left side of the conveyor cylinder body 1, and the output shaft of the motor is fixedly connected with the screw shaft 2.

[0043] By adopting the above technical solution, a feed pipe is inserted into the top left side of the conveyor cylinder body 1, and a discharge pipe is inserted into the top right side of the conveyor cylinder body 1. When conveying, the protein powder enters through the feed pipe at the top left side of the conveyor cylinder body 1, and then the output shaft of the motor rotates, causing the screw shaft 2 to rotate. In this way, the screw blades can rotate to realize the conveying of the material until the material is discharged from the bottom left side of the conveyor cylinder body 1.

[0044] During the process of material transportation, cooling water is provided inside the cooling chamber 3, and the cold water cools the protein powder transported inside the conveying cylinder 1.

[0045] The cold water in the cooling chamber 3 absorbs the heat inside the conveying cylinder 1 to cool the powder. During the transportation of the material, the spiral shaft 2 rotates, which causes the scraping frame 41 to rotate accordingly. When the scraping frame 41 rotates to the bottom position inside the conveying cylinder 1, the scraping frame 41 can turn over the accumulated powder. Such a design can reduce the situation where the powder inside the powder accumulation area is difficult to exchange heat with the inside of the conveying cylinder 1, thereby improving the cooling uniformity and the cooling effect.

[0046] When the scraping frame 41 rotates, the scraping strip 42 rotates accordingly, so that the scraping strip 42 scrapes the inner wall of the conveying cylinder 1, reducing the adhesion of some powder to the inner wall of the conveying cylinder 1 and affecting the heat exchange efficiency between the cooling water and the inside of the conveying cylinder 1, thereby improving the cooling efficiency of the powder.

[0047] The cooling chamber 3 is provided inside the circumferential side of the conveying cylinder 1, and there are two cooling chambers 3, and different temperatures of water are introduced into the two cooling chambers 3.

[0048] The cooling process is divided into two stages, and different temperatures are controlled in each stage to gradually reduce the temperature of the material instead of sudden cooling. This reduces the temperature difference between the surface of the material and the ambient air, avoids the local temperature dropping below the dew point, avoids the appearance of condensed water causing the powder to be wet and sticky, thereby avoiding affecting the transportation efficiency, and avoids the situation where the condensed water adheres to the inner wall of the conveying cylinder 1 with the powder, avoiding the adhesion from affecting the heat exchange efficiency.

[0049] The dispersion component 4 further includes an elastic film 43 fixed to one side of the scraping frame 41 in the rotation direction. The inside of the scraping frame 41 is filled with a medium. The dispersion component 4 further includes a transition cylinder 44 arranged inside the spiral shaft 2. A first piston plate 45 is arranged inside the transition cylinder 44. A straight pipe 46 is fixedly inserted between the transition cylinder 44 and the scraping frame 41. The straight pipe 46 is made of a rigid material. The movement of the first piston plate 45 inside the transition cylinder 44 changes the pressure inside the scraping frame 41, thereby deforming the elastic film 43. A transmission component 5 for controlling the movement of the first piston plate 45 is arranged inside the spiral shaft 2. The transition cylinder 44 is fixed to the inner side of the spiral shaft 2 through the straight pipe 46. The transmission component 5 includes a long shaft 51 rotating inside the spiral shaft 2, and its right side passes through the spiral shaft 2 and is fixed to the conveying cylinder body 1. A connecting frame 52 is arranged on the outer wall of the long shaft 51. A limiting part 53 is arranged on the outside of the connecting frame 52. The limiting part 53 includes an annular body 531, and the annular body 531 is fixed to the connecting frame 52. The transmission component 5 further includes a lifting shaft 54 fixed to the side of the first piston plate 45 close to the spiral shaft 2. A circular shaft 55 is rotatably connected to the outer wall of the lifting shaft 54. The design of the rotation of the circular shaft 55 is beneficial to reducing the friction during movement. The circular shaft 55 extends into the inside of the limiting part 53. The circular shaft 55 moves along the inside of the limiting part 53 to control the lifting shaft 54 to drive the first piston plate 45 to move. A cushioning ring 532 is fixed to the front end of the inner bottom of the annular body 531, and a transition arc ring 533 is fixed to the rear end of the inner bottom of the annular body 531. The design of the transition arc ring 533 and the cushioning ring 532 makes the distance between the inner bottom of the limiting part 53 and the center of the annular body 531 smaller than the distance between the inner top of the limiting part 53 and the center of the annular body 531.

[0050] By adopting the above technical solution, the elastic film 43 is made of a material with elasticity and corrosion resistance. When the scraping frame 41 rotates to the upper position of the spiral shaft 2, under the action of its own elasticity, the elastic film 43 is in a relatively flat state. And under the action of the elasticity of the elastic film 43, the first piston plate 45 is inside the transition cylinder 44 and is located at a position far from the limiting part 53, and at this time the circular shaft 55 is located at the inner top position of the annular body 531. As the spiral shaft 2 drives the scraping frame 41 to rotate, the circular shaft 55 rotates along the inside of the limiting part 53. When the scraping frame 41 rotates to the bottom position with the spiral shaft 2, the circular shaft 55 is limited by the transition arc ring 533 during the movement process and gradually reaches the bottom position of the limiting part 53. Since the distance between the inner bottom of the limiting part 53 and the center of the annular body 531 is small, when the circular shaft 55 moves to the bottom position of the limiting part 53, the circular shaft 55 drives the lifting shaft 54 and the first piston plate 45 to move towards the center of the annular body 531. In this way, the space inside the transition cylinder 44 and on the side of the first piston plate 45 close to the scraping frame 41 becomes larger, so that the medium inside the scraping frame 41 enters the inside of the scraping frame 41, which reduces the pressure of the medium inside the scraping frame 41. Such a design makes the elastic film 43 deform and sink inward.

[0051] When the scraping frame 41 rotates to the bottom position, the elastic film 43 is recessed. Subsequently, as the scraping frame 41 continues to rotate, the recessed part of the elastic film 43 shovels up some powder, and during the subsequent rotation of the scraping frame 41, the powder is dispersed, improving the powder dispersion effect, further enhancing the heat exchange effect of the powder, and improving the cooling effect of the powder.

[0052] As the scraping frame 41 rotates to the top position, under the elastic force of the elastic film 43, the first piston plate 45, the circular shaft 55, and the lifting shaft 54 reset. At this time, the circular shaft 55 returns to the position at the top of the limiting part 53, and the elastic film 43 returns to a relatively flat state.

[0053] An arc groove 534 is provided inside the additional cushion ring 532, and a plurality of arc grooves 534 are provided. Along the rotation direction of the scraping frame 41, the width of the arc groove 534 gradually increases. The inner bottom of the additional cushion ring 532 is concentric with the ring body 531.

[0054] By adopting the above technical solution, as the scraping frame 41 rotates, when the circular shaft 55 rotates to the position of the additional cushion ring 532 and continues to rotate, the elastic film 43 contains powder inside. When the circular shaft 55 rotates to the first arc groove 534, under the elastic force of the elastic film 43, the first piston plate 45, the circular shaft 55, and the lifting shaft 54 move, causing the elastic film 43 to deform rapidly and the degree of depression of the elastic film 43 to decrease. When the elastic film 43 deforms rapidly, some of the powder inside the depression of the elastic film 43 can be quickly shaken out and dispersed, thus further facilitating the improvement of the powder dispersion effect and the cooling effect of the powder.

[0055] When the circular shaft 55 rotates to the next arc groove 534, the first piston plate 45, the circular shaft 55, and the lifting shaft 54 repeat the previous movement to gradually disperse the remaining powder.

[0056] The inner bottom of the ring body 531 is annularly and integrally fixed with a first shaking block 56.

[0057] By adopting the above technical solution, when the circular shaft 55 rotates through the position of the first shaking block 56, due to the limitation of the plurality of first shaking blocks 56, the first piston plate 45, the circular shaft 55, and the lifting shaft 54 can synchronously shake and move along the axis of the lifting shaft 54. Due to the movement of the first piston plate 45, such a design causes the internal medium pressure of the scraping frame 41 to change, resulting in a rapid deformation change of the elastic film 43, which is conducive to the detachment of the powder adhered to its surface and reduces the influence of excessive impurities adhered to the elastic film 43 on the conveying efficiency.

[0058] The water cooling conveying device further includes a turning component 6. One side of the scraping frame 41 where the turning direction is opposite is fixedly connected with a rubber pad 61. The inner wall of the rubber pad 61 is fixedly connected with a fixing rod 62. A stirring plate 63 is fixedly connected to the outer wall of the fixing rod 62. The turning component 6 further includes a small rod 64 fixedly connected to the side of the first piston plate 45 away from the lifting shaft 54. The end of the small rod 64 passes through the inside of the straight pipe 46 and extends into the inside of the scraping frame 41 to fixedly connect a lifting plate 611. The turning component 6 further includes a mounting plate 65 fixedly connected to the inside of the scraping frame 41. A corrugated bladder 66 is fixedly connected to the bottom of the mounting plate 65. A conduit 67 is fixedly inserted into the top of the corrugated bladder 66. The end of the conduit 67 away from the corrugated bladder 66 is fixedly inserted with a connecting cylinder 68. A second piston plate 69 is movably arranged inside the connecting cylinder 68. An extrusion rod 610 for extruding the fixing rod 62 is fixedly connected to the outer wall of the second piston plate 69. The end of the extrusion rod 610 passes out of the connecting cylinder 68 and is rotatably connected with a ball. The bottom inner side of the cushioning ring 532 is fixedly connected with second shaking blocks 12 in an annular array.

[0059] By adopting the above technical solution, when the scraping frame 41 rotates to the lower side and the round shaft 55 rotates to the bottom of the cushioning ring 532, at this time, the first piston plate 45 moves to a position close to the scraping frame 41. Since the small rod 64 and the mounting plate 65 can move along with the first piston plate 45, the mounting plate 65 is close to the corrugated bladder 66 but does not extrude the corrugated bladder 66. Under the action of the gravity of the stirring plate 63, the fixing rod 62 and the stirring plate 63 are in a state of tilting and falling. At this time, the fixing rod 62 is located inside the scraping frame 41 and fits and presses against the extrusion rod 610, ensuring that the corrugated bladder 66 is in an expanded state and is not affected by the internal pressure of the scraping frame 41. It should be noted that the fixing rod 62 and the stirring plate 63 are made of hollow materials and their gravity is moderate.

[0060] As the scraping frame 41 rotates, when the rotation of the round shaft 55 is limited by the second shaking blocks 12, the first piston plate 45, the round shaft 55 and the lifting shaft 54 move. The first piston plate 45 drives the small rod 64 and the mounting plate 65 to extrude the corrugated bladder 66. The hydraulic oil arranged inside it enters the inside of the connecting cylinder 68 through the conduit 67. Under the action of the hydraulic oil pressure, the second piston plate 69 drives the extrusion rod 610 to move towards the direction close to the fixing rod 62. The extrusion rod 610 extrudes the fixing rod 62, so that the fixing rod 62 and the stirring plate 63 further turn the piled powder, further improving the heat exchange effect of the powder.

[0061] When the scraping frame 41 rotates to the upper side, the first piston plate 45 drives the small rod 64 and the mounting plate 65 away from the corrugated bladder 66.

[0062] It should be noted that the corrugated bladder 66 is made of a metallic material. The rubber gasket 61 is arranged later. When the medium pressure inside the scraping frame 41 changes when the scraping frame 41 rotates to the lower side, it will not cause deformation of the corrugated bladder 66 and the rubber gasket 61.

[0063] The diameter of the corrugated bladder 66 is larger than the diameter of the connecting cylinder 68. When the compression amount of the corrugated bladder 66 is small, the second piston plate 69 drives the extrusion rod 610 to move a large distance, thereby increasing the swing amplitude of the fixed rod 62 and the stirring plate 63, and further improving the turning effect.

[0064] Embodiment 2: As Figure 1 、 Figure 2 and Figure 12 shown, the technical solution of this embodiment is different from that of Embodiment 1 in that: a processing box 7 is fixedly connected to the middle part of the circumferential side of the conveying cylinder body 1. Water guide pipes 8 are fixedly connected to both sides of the processing box 7. The end portions of the two water guide pipes 8 away from the processing box 7 are respectively inserted into the interiors of the two cooling cavities 3. A heating component for heating water is installed at the rear end of the processing box 7. The heating component is a mature prior art and can be an electric heating wire, which is a mature prior art. A temperature measuring sensor 9 is installed on the top of the processing box 7. Fixed partitions 10 are linearly arrayed inside the processing box 7. Through grooves 11 are formed in the partitions 10, and the through grooves 11 of adjacent partitions 10 are staggered.

[0065] By adopting the above technical solution, two cooling cavities 3 are provided, filled with cold water at different temperatures. The right cooling cavity 3 is plugged with an inlet pipe, and the left cooling cavity 3 is plugged with an outlet pipe. Cold water at a lower temperature is pumped into the inlet pipe through a water pump. The cold water enters the right cooling cavity 3, then passes through the right water guide pipe 8 into the processing box 7, and then passes through the left water guide pipe 8 into the left cooling cavity 3, and is discharged from the outlet pipe for re-refrigeration.

[0066] In the initial stage, after the cold water enters the processing box 7, the temperature measuring sensor 9 detects that the incoming temperature is relatively low, and the heating component heats the incoming cold water to ensure that the cold water in the left cooling cavity 3 has a higher temperature. After running for a period of time, the cooling water will absorb heat when it enters the right cooling cavity 3, which can supplement the water temperature. When the temperature of the water entering the processing box 7 is sufficient, there is no need to heat it through the heating component. When the water temperature entering the processing box 7 is too high, the flow rate of the cooling water is increased. When the water temperature entering the processing box 7 is too low, the flow rate of the cooling water can be reduced by the water pump.

[0067] The design of the partitions 10 and the through grooves 11 is conducive to prolonging the circulation time of water in the processing box 7. When initially heating, it is conducive to increasing the heating time of water and improving the heating efficiency.

[0068] A method for using a plant protein powder solution includes the following steps:

[0069] S1. The protein powder enters from the feed pipe at the top left of the conveying cylinder 1, and then the output shaft of the motor rotates to drive the spiral shaft 2 to rotate. This enables the spiral blades to rotate and convey the material until the material is discharged from the bottom left of the conveying cylinder 1.

[0070] S2. Cooling: During the material conveyance process, cooling water is provided inside the cooling chamber 3 to cool the protein powder conveyed inside the conveying cylinder 1.

[0071] Working principle: During the material conveyance process, when the spiral shaft 2 rotates, the scraping frame 41 rotates accordingly. When the scraping frame 41 rotates to the bottom position inside the conveying cylinder 1, the scraping frame 41 can turn over the accumulated powder. This design can reduce the situation where the powder inside the accumulated powder area is difficult to exchange heat with the inside of the conveying cylinder 1, thereby improving the uniformity of cooling and enhancing the cooling effect.

[0072] As the spiral shaft 2 drives the scraping frame 41 to rotate, the round shaft 55 rotates along the inside of the limiting part 53. When the scraping frame 41 rotates to the bottom position along with the spiral shaft 2, during the movement of the round shaft 55, it is limited by the arc-shaped ring 533 and gradually reaches the bottom position of the limiting part 53. Since the distance between the inner bottom of the limiting part 53 and the center of the ring body 531 is relatively small, when the round shaft 55 moves to the bottom position of the limiting part 53, the round shaft 55 drives the lifting shaft 54 and the first piston plate 45 to move towards the center of the ring body 531. This makes the space inside the transition cylinder 44 and on the side of the first piston plate 45 close to the scraping frame 41 become larger, so that the medium inside the scraping frame 41 enters the inside of the scraping frame 41, reducing the pressure of the medium inside the scraping frame 41. This design causes the elastic film 43 to deform and sink inward.

[0073] Since the elastic film 43 sinks when the scraping frame 41 rotates to the bottom position, and then as the scraping frame 41 continues to rotate, the sunken part of the elastic film 43 shovels up some of the powder and disperses the powder during the subsequent rotation of the scraping frame 41, improving the powder dispersion effect, further enhancing the powder heat exchange effect, and thus improving the powder cooling effect.

[0074] As the scraping frame 41 rotates, when the round shaft 55 rotates to the position of the cushioning ring 532 and continues to rotate, the inside of the elastic film 43 contains powder. When the round shaft 55 rotates to the first arc groove 534, under the elastic force of the elastic film 43, the first piston plate 45, the round shaft 55, and the lifting shaft 54 move, causing the elastic film 43 to deform rapidly and the degree of depression of the elastic film 43 to decrease. When the elastic film 43 deforms rapidly, some of the powder inside the depression of the elastic film 43 can be quickly shaken out and dispersed, which further helps to improve the powder dispersion effect and is conducive to enhancing the powder cooling effect.

[0075] When the circular shaft 55 rotates to the next arc groove 534, the first piston plate 45, the circular shaft 55 and the lifting shaft 54 repeat the previous movement to gradually disperse the remaining powder material.

[0076] As the scraping frame 41 rotates, when the rotation of the circular shaft 55 is limited by the second jitter block 12, the first piston plate 45, the circular shaft 55 and the lifting shaft 54 move. The first piston plate 45 drives the small rod 64 and the mounting plate 65 to squeeze the corrugated bladder 66. The hydraulic oil arranged inside it enters the inside of the connecting cylinder 68 through the conduit 67. Under the action of the hydraulic oil pressure, the second piston plate 69 drives the extrusion rod 610 to move towards the direction close to the fixed rod 62. The extrusion rod 610 extrudes the fixed rod 62, so that the fixed rod 62 and the stirring plate 63 further turn over the piled powder material, further improving the heat exchange effect of the powder material.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
