[0002] Whey is an important by-product in the dairy industry. During the cheese production process, milk is separated into solid curds and liquid whey. Whey is rich in protein, lactose and other nutrients, so it has high value in the food processing industry.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0036] like Figures 1 to 7As shown, a dairy product additive drying and powdering device of the present invention comprises a drying cylinder 1, a partition cylinder 2, a cone disk 3 and a feed pipe 4, the drying cylinder 1 is vertical, the interior of the drying cylinder 1 is used to provide space for drying raw materials, the partition cylinder 2 is coaxially located inside the drying cylinder 1, the internal space of the partition cylinder 2 is used as a raw material dispersion space, the space between the outer wall of the partition cylinder 2 and the inner wall of the drying cylinder 1 is used as a raw material reverse fluidization space, the cone disk 3 and the feed pipe 4 are distributed up and down and are both located in the partition cylinder 2, the cone disk 3 is fixed in the partition cylinder 2, the bottom of the feed pipe 4 passes through the drying cylinder 1 and extends out, and the raw materials discharged upward from the feed pipe 4 impact on the cone disk 3 and diffuse;

[0037] The bottom of the drying cylinder 1 is set to be conical, and a plurality of exhaust passages 5 for supplying normal temperature airflow toward the interior of the partition cylinder 2 are opened at the bottom of the drying cylinder 1;

[0038] The outer wall of the drying cylinder 1 is provided with a heating groove 6, and a plurality of nozzles 7 are connected to the heating groove 6. The nozzles 7 extend into the drying cylinder 1, and the nozzle openings of the nozzles 7 are inclined upward and toward the axis of the drying cylinder 1. The nozzles 7 are used to supply hot air flow into the drying cylinder 1. An electric heating plate 8 is provided in the heating groove 6;

[0039] Wherein, a collecting structure is arranged on the top of the drying cylinder 1, and the collecting structure is used to collect the dried powder raw materials.

[0040] In detail, the partition cylinder 2 is located at the lower side of the interior of the drying cylinder 1, the space inside the partition cylinder 2 is used to atomize the raw materials, the space between the partition cylinder 2 and the drying cylinder 1 is used for the undispersed raw materials to flow back to the lower side of the interior of the drying cylinder 1, and the internal space of the drying cylinder 1 on the upper side of the partition cylinder 2 is used to heat and dry the atomized and dispersed raw materials. The partition cylinder 2 can be fixed on the inner wall of the drying cylinder 1 by a bracket, the cone disk 3 is located on the upper side of the interior of the partition cylinder 2, the pointed end of the cone disk 3 faces downward, and the cone disk 3 can be fixed on the inner wall of the partition cylinder 2 by a bracket, the feed pipe 4 is located below the cone disk 3, and the top opening of the feed pipe 4 is upwardly facing the cone disk 3. When the raw materials are sprayed upward onto the cone disk 3 through the feed pipe 4, the raw materials impact on the cone disk 3 and diffuse around. A plurality of exhaust channels 5 are provided at the bottom of the drying cylinder 1, and the plurality of exhaust channels 5 supply high-speed airflow into the partition cylinder 2. The high-speed airflow can be a normal temperature airflow. The airflow will impact and diffuse the dispersed droplets in the partition cylinder 2, so that the droplets are fully dispersed and atomized, and the atomized raw materials follow As the airflow enters the upper side of the drying cylinder 1, the larger droplets on the upper side of the drying cylinder 1 can move toward the inner wall of the drying cylinder 1 due to the action of the airflow and fall under the influence of gravity. These droplets will pass through the space between the drying cylinder 1 and the partition cylinder 2 and fall into the vicinity of the multiple exhaust channels 5 on the lower side of the drying cylinder 1 and be impacted upward again by the high-speed airflow discharged from the exhaust channels 5, thereby fully fluidizing and atomizing the droplets. The electric heating plate 8 in the heating tank 6 can heat the air in the heating tank 6 and form high-temperature gas. The high-temperature gas can be sprayed into the vicinity of the atomized raw materials on the upper side of the drying cylinder 1 through multiple nozzles 7, thereby utilizing the high-temperature gas to dry the raw materials. At this time, the raw materials are atomized, so that the raw materials can be fully dried to avoid mutual obstruction between the raw materials. The dried raw materials can be gathered through the collecting structure, thereby realizing the drying of the raw materials, and the equipment can realize a continuous drying treatment method for the raw materials when in use.

[0041] It should be pointed out that, since the raw materials are atomized by impact atomization and airflow impact atomization, compared with directly using an atomizing nozzle, the present invention can avoid clogging of the nozzle by the raw materials and can achieve large flow and rapid drying.

[0042] The equipment uses the impact of high-speed airflow and the impact and dispersion effect of the raw materials and the cone disk 3 to evenly disperse the raw materials during drying, so that the high-temperature airflow sprayed by multiple nozzles 7 can fully dry the raw materials, avoid the situation where the evaporation of water inside the raw materials is blocked, ensure the uniformity of the drying process, and improve the product quality; the combination of high-speed airflow and hot airflow accelerates the evaporation rate of water, reduces the time and energy required for drying, and significantly improves the drying efficiency and reduces energy consumption compared with traditional methods; the raw materials are fully atomized during the drying process, reducing the contact area between particles, effectively preventing the agglomeration of whey powder during the drying process, and maintaining the fluidity and use performance of the product; the design of the equipment allows continuous feeding and discharging, improves production efficiency, and is suitable for the needs of large-scale industrial production; in summary, the technical solution effectively solves the problems existing in the traditional drying method through innovative structural design and efficient drying mechanism, and provides a more advanced, efficient and economical solution for the drying and pulverization of whey powder.

[0043] Furthermore, the exhaust passage 5 is in a vertical Z-shape, and the angles between the middle portion of the Z-shape and the two side portions of the Z-shape are both acute angles.

[0044] In detail, by limiting the shape of the exhaust channel 5, the raw materials can be prevented from flowing directly to the bottom of the drying cylinder 1 through the exhaust channel 5, thereby preventing the leakage of raw materials. In addition, this structural method can facilitate the airflow to directly blow out the raw materials entering the exhaust channel 5, thereby achieving the sealing work of the raw materials.

[0045] Furthermore, the conical surface of the conical disk 3 is composed of a plurality of annular arc surfaces, and the diameters of the plurality of annular arc surfaces gradually decrease from top to bottom.

[0046] In detail, when the raw material impacts the arc surface, the arc surface can be used to disperse the raw material in the horizontal and vertical directions, and multiple annular arc surfaces can make the raw material diffuse in multiple levels in the vertical direction, and two adjacent layers can diffuse through each other, thereby improving the raw material diffusion area and diffusion uniformity.

[0047] Furthermore, the collection structure includes a buckle plate 9 buckled on the outside of the drying cylinder 1, a recovery corridor is formed between the inner wall of the buckle plate 9 and the outer wall of the drying cylinder 1, and the bottom of the recovery corridor is inclined, an exhaust buckle cover 11 is provided at the middle position of the top of the buckle plate 9, a conical filter plate 10 is buckled at the bottom opening position of the exhaust buckle cover 11, and an exhaust pipe 25 is connected to the exhaust buckle cover 11.

[0048] In detail, the dried raw materials in the drying cylinder 1 are moved upward by the airflow. When the raw materials reach the position of the conical filter plate 10, the conical filter plate 10 intercepts the raw materials. The air can enter the exhaust buckle cover 11 through the conical filter plate 10. The air in the exhaust buckle cover 11 can be discharged through the exhaust pipe 25. Due to the shape of the conical filter plate 10, the airflow can blow the raw materials intercepted by the conical filter plate 10 to the surroundings, so that the raw materials enter the recovery corridor between the buckle plate 9 and the drying cylinder 1, thereby realizing the collection of the dry raw materials. Since the bottom of the recovery corridor is inclined, it is convenient for the raw materials to gather.

[0049] Further, the conical filter disc 10 rotates on the exhaust buckle cover 11, and the exhaust buckle cover 11 is fixed on the buckle plate 9. Two partition plates 12 are rotatably arranged in the exhaust buckle cover 11, and the two partition plates 12 divide the internal space of the exhaust buckle cover 11 into an exhaust chamber 13, a gas chamber 14 and a partition chamber 15 from top to bottom. A plurality of partition plates 16 are arranged in the partition chamber 15, and the plurality of partition plates 16 divide the internal space of the partition chamber 15 into a plurality of exhaust spaces and a plurality of recoil spaces, and the exhaust space is located between two adjacent recoil spaces, the recoil space is connected to the gas chamber 14 through a circular hole 17, the exhaust space is connected to the exhaust chamber 13 through a secondary pipe 18, and the exhaust pipe 25 is connected to the exhaust chamber 13;

[0050] The bottom surface of the conical filter disc 10 is provided with a plurality of arc-shaped plates 19 .

[0051] In detail, the exhaust buckle cover 11 is coaxial with the two partition plates 12. When the air filtered by the conical filter plate 10 enters the exhaust space, the air goes up and enters the exhaust chamber 13 through the auxiliary pipe 18. At this time, the air can be discharged smoothly through the exhaust pipe 25, and the gas in the air chamber 14 can be filled into the recoil space through the circular hole 17. The gas in the recoil space can pass downward through the conical filter plate 10 and be blown into the drying cylinder 1. At this time, the raw materials that block the filter holes on the conical filter plate 10 can be cleaned, so that the conical filter plate 10 maintains a high air permeability.

[0052] When the air in the drying cylinder 1 is blown to the bottom surface of the conical filter disc 10, the air can push the conical filter disc 10 to rotate with the help of multiple arc plates 19, so that the filter holes on the conical filter disc 10 circulate between the exhaust space and the backwash space, so that the conical filter disc 10 can be continuously cleaned while ensuring continuous exhaust.

[0053] Furthermore, an auxiliary gas bin 20 is provided at the bottom of the drying cylinder 1, and multiple exhaust channels 5 are connected to the auxiliary gas bin 20. An air inlet pipe 21 is provided on the auxiliary gas bin 20. The auxiliary gas bin 20 is connected to the heating tank 6 through a first conduit 22, and the heating tank 6 is connected to the air charging chamber 14 through a second conduit 23. A pressure regulating valve 24 is provided on the second conduit 23.

[0054] In detail, the outside air can be pumped into the auxiliary air tank 20 through the air inlet pipe 21, and the air in the auxiliary air tank 20 can be discharged into the partition tube 2 through multiple exhaust channels 5. At the same time, the air in the auxiliary air tank 20 can enter the heating tank 6 through the first conduit 22. The electric heating plate 8 heats the air in the heating tank 6, so that the nozzle 7 discharges high-temperature airflow. The excess air in the heating tank 6 can be discharged into the air chamber 14 through the second conduit 23, so as to replenish the gas for the recoil space. The pressure regulating valve 24 can adjust the amount of air entering the recoil space, so as to ensure that both the nozzle 7 and the exhaust channel 5 can have sufficient air to discharge.

[0055] Furthermore, a vertical sleeve 27 is provided on the outer wall of the gusset plate 9, a material opening 26 is opened on the gusset plate 9, the material opening 26 is communicated with the inside of the sleeve 27, and a shield plate 28 is provided at the bottom of the sleeve 27;

[0056] A moving body 29 is vertically slidably disposed in the sleeve 27 , and a receiving passage 30 is provided on the moving body 29 .

[0057] In detail, the moving body 29 can move up and down in the sleeve 27, and the storage channel 30 is located at the lower side of the moving body 29, and the storage channel 30 is inclined. When the storage channel 30 is connected with the material port 26, the left side of the storage channel 30 is blocked by the inner wall of the sleeve 27. At this time, the raw materials in the recovery corridor can enter the storage channel 30 through the material port 26. When the moving body 29 moves downward, the side wall of the moving body 29 blocks the material port 26. At this time, the raw materials cannot enter the storage channel 30. When the storage channel 30 moves out to the bottom of the sleeve 27, the left side of the storage channel 30 is opened, and the right side of the storage channel 30 is blocked by the baffle 28. At this time, the raw materials in the storage channel 30 can be discharged naturally. When the moving body 29 moves upward to the initial position, the storage channel 30 receives the raw materials again, so that the discharge of the raw materials can be achieved while ensuring the sealing of the recovery corridor.

[0058] Furthermore, a first adjusting arm 31 is rotatably provided on the side wall of the movable body 29, and a second adjusting arm 32 is rotatably connected to the first adjusting arm 31. A supporting column 33 is rotatably provided on the side wall of the sleeve 27, and the second adjusting arm 32 slides through the supporting column 33. A motor 34 is provided on the sleeve 27, and a power disk 35 is provided at the output end of the motor 34. The end of the second adjusting arm 32 is eccentrically rotatably mounted on the end face of the power disk 35.

[0059] In detail, when the motor 34 is running, it can drive the power disk 35 to rotate, and the power disk 35 can drive the second adjusting arm 32 to tilt and swing. The support column 33 provides a lever support effect for the second adjusting arm 32.
