Description

Technical Field

[0001] This invention relates to the field of goat milk powder preparation technology, specifically a low-temperature drying apparatus and method for producing goat milk powder. Background Technology

[0002] Existing goat milk powder typically requires a drying process to remove moisture during preparation, in order to facilitate storage and transportation. Traditional drying methods often employ high-temperature spray drying, which, while fast, can easily destroy heat-sensitive nutrients in goat milk, such as vitamins, lactoferrin, and immunoglobulins, thus reducing the nutritional value of the goat milk powder.

[0003] Meanwhile, high temperatures may also cause milk powder to have a burnt taste, affecting the product flavor. In addition, some drying devices have problems such as uneven drying, easy clumping of milk powder, and poor production continuity, resulting in unstable quality of goat milk powder and difficulty in meeting the market demand for high-quality goat milk powder. Therefore, it is of great significance to have a drying device and method that can achieve efficient drying under low temperature conditions, while effectively preserving the nutritional components of goat milk and ensuring uniform quality of milk powder. Summary of the Invention

[0004] The purpose of this invention is to provide a low-temperature drying apparatus and method for producing goat milk powder, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature drying device for producing goat milk powder, the drying device comprising a concentration component, a low-temperature drying component, and a driving component, the low-temperature drying component comprising a plurality of supporting components and a drying unit, a feeding pipe installed at the output end of the concentration component, the output end of the feeding pipe being disposed on the supporting component, a pulverizing component being disposed on the supporting component, and the driving component cooperating with the pulverizing component;

[0006] The drying unit uses low-temperature hot air to dry the concentrated sheep milk on the carrier component.

[0007] The bearing assembly includes several bearing plates, and adjustment components are installed on both sides of the bearing plates. The output end of the feeding pipe is respectively set on each bearing plate. The adjustment component includes an adjustment motor and an adjustment shaft. The output end of the adjustment motor is connected to the adjustment shaft, and the adjustment shaft is connected to the bearing plate. A collection hopper is provided at the bottom of the bearing plate, and a crushing component is provided at the bottom of the collection hopper.

[0008] Some drying devices suffer from uneven drying, easy clumping of milk powder, and poor production continuity, resulting in unstable quality of goat milk powder and difficulty in meeting market demand for high-quality goat milk powder.

[0009] Furthermore, the pulverizing assembly includes a pulverizing tank, and the driving assembly includes a driving motor and a driving rod. The driving rod is installed inside the pulverizing tank, and the driving motor is installed at the bottom of the pulverizing tank. The driving rod and the driving motor are connected by magnetic coupling. The driving rod is provided with a pulverizing structure and a wall scraping structure. The pulverizing structure and the wall scraping structure cooperate with each other. The driving rod is provided with a bidirectional threaded groove.

[0010] Some drying devices have problems such as uneven drying, easy clumping of milk powder, and poor production continuity, resulting in unstable quality of goat milk powder.

[0011] Furthermore, the pulverizing structure includes a plurality of pulverizing rods, which are equidistantly installed at the bottom of the drive rod. A plurality of support rods are provided on the pulverizing rods. The wall scraping structure includes a mating ring and a wall scraping ring. A bidirectional threaded groove is provided in the mating ring. The mating ring is connected to the drive rod for transmission. The wall scraping ring is in contact with the inner wall of the pulverizing tank. The mating ring and the wall scraping ring are fixed by a plurality of fixing rods. A plurality of scrapers are provided on the side of the wall scraping ring that is in contact with the inner wall of the pulverizing tank.

[0012] Existing pulverizing devices often result in incomplete pulverization or particles adhering to the tank wall when pulverizing dried goat milk curds, leading to clumping and residue. This invention addresses this by using a high-speed rotating pulverizing rod to break up clumping, while a scraper ring moves a scraper up and down along the tank wall to remove adhering particles, ensuring uniform pulverization.

[0013] Furthermore, the tilting direction of some of the scrapers is matched with the moving direction of the mating ring;

[0014] When the ring moves down or up along the drive rod: the scraper on the scraper ring can scrape off the milk powder on the inner wall of the crushing tank.

[0015] Furthermore, the drying unit includes several heating devices and temperature sensors. The heating devices are equidistantly arranged on the side of the support plate, and the temperature sensors cooperate with the heating devices.

[0016] Furthermore, the concentration assembly includes a concentration tank and a vacuum pump. A heating unit is provided inside the jacket of the concentration tank, a feed pump is provided at the output end of the concentration tank, a feed pipe is provided at the output end of the feed pump, and the vacuum pump is connected to the concentration tank.

[0017] The integrated concentration unit enables preliminary concentration of goat milk without the need for additional transfer equipment, effectively reducing material loss and contamination risks during transfer. During concentration, a vacuum pump quickly removes air from the concentration tank, lowering the internal pressure and allowing the goat milk to boil and evaporate water at a lower temperature, thus preventing the destruction of nutrients by high temperatures.

[0018] Furthermore, a drive device is installed above the concentration tank, and a stirring assembly is provided inside the concentration tank. The stirring assembly includes a stirring rod, and several support rods are provided on the stirring rod. Several auxiliary rods are installed at the other end of the support rods through bearings.

[0019] Existing concentration tanks only use a fixed stirring structure to stir the goat milk inside, which does not achieve optimal heating efficiency.

[0020] Furthermore, the drying device includes a housing, inside which are arranged the concentration component, the low-temperature drying component, the pulverizing component, and a controller. The controller is electrically connected to the concentration component, the low-temperature drying component, and the pulverizing component via wires. A control panel is provided outside the housing, and the control panel is electrically connected to the controller.

[0021] Furthermore, the drying method includes the following steps: S1, introducing goat milk into the concentration component;

[0022] S2. The concentrated goat milk is dried using a low-temperature drying unit.

[0023] S3. The crushing component crushes the dried goat milk blocks.

[0024] Furthermore, S1 includes S11, a concentration component that concentrates goat milk to 1 / 4 of its original volume;

[0025] S2 includes S21, where the concentrated goat milk is first evenly sprayed onto the support plate;

[0026] S22. The drying unit dries the goat milk on the support plate at a low temperature.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. By adopting a low-temperature hot air drying method combined with vacuum low-temperature concentration technology, the damage to heat-sensitive nutrients such as vitamins and lactoferrin in goat milk caused by traditional high-temperature drying is effectively avoided, significantly improving the nutritional value and flavor of goat milk powder.

[0029] 2. The adjustable tilt design of the support plate allows the goat milk to be spread evenly and flow slowly. Combined with the side-mounted heating device, it achieves uniform heating and consistent drying. The wall scraping structure in the pulverizing component can move up and down with the drive rod to thoroughly scrape off the milk powder adhering to the tank wall, avoid lumps and residues, and ensure that the milk powder particles are fine and uniform.

[0030] 3. The device integrates concentration, drying, and pulverization into one unit, realizing continuous operation from raw materials to finished products, reducing material transfer pollution and loss; equipped with a controller and sensor system, it can realize automatic control of parameters such as temperature and concentration, improve production efficiency and product consistency, and is suitable for large-scale production of high-quality goat milk powder.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example: Figures 1-9 As shown, the present invention provides a low-temperature drying device and method for producing goat milk powder. The drying device includes a concentration component 1, a low-temperature drying component and a drive component 6. The low-temperature drying component includes several support components 2 and a drying unit 3. A feed pipe is installed at the output end of the concentration component 1. The output end of the feed pipe is set on the support component 2. A crushing component 4 is set on the support component 2. The drive component 6 cooperates with the crushing component 4.

[0043] Drying unit 3 dries the concentrated sheep milk on carrier component 2 using low-temperature hot air;

[0044] The bearing assembly 2 includes several bearing plates 21. Adjustment assemblies 5 are installed on both sides of the bearing plates 21 respectively. The output end of the feeding pipe is respectively set on each set of bearing plates 21. The adjustment assembly 5 includes an adjustment motor 51 and an adjustment shaft. The output end of the adjustment motor 51 is connected to the adjustment shaft. The adjustment shaft is connected to the bearing plate 21. A collection hopper is set at the bottom of the bearing plate 21. A crushing assembly 4 is set at the bottom of the collection hopper.

[0045] When using this device, the sheep milk is first pre-treated by the concentration component 1, concentrating it to a suitable concentration. Then, it is evenly conveyed to each support plate 21 through the feeding pipe. At this time, the adjustment component 5 starts to work, and the adjustment motor 51 drives the adjustment shaft to rotate, thereby adjusting the support plate 21 to a suitable tilt angle to ensure that the sheep milk can be evenly spread and flow slowly on the support plate 21. During the flow of sheep milk, the drying unit 3 continuously delivers low-temperature hot air to perform low-temperature drying treatment on the concentrated sheep milk on the support plate 21. As the drying process proceeds, the moisture in the sheep milk gradually evaporates, forming a thin layer of pre-dried milk powder. When the milk powder layer moves to the end of the support plate 21, it will fall into the collection hopper at the bottom. After the collection hopper collects a certain amount of milk powder, the drive component 6 is started, driving the crushing component 4 to crush the milk powder, breaking the clumps of milk powder into a uniform powder, and finally obtaining high-quality sheep milk powder. The whole process realizes continuous production from sheep milk concentration, low-temperature drying to milk powder crushing, effectively ensuring the nutritional components and quality of sheep milk powder.

[0046] like Figure 2 , Figure 6 and Figure 9As shown, in this embodiment, specifically, the crushing component 4 includes a crushing tank 41, and the driving component 6 includes a driving motor 61 and a driving rod 62. The driving rod 62 is installed inside the crushing tank 41, and the driving motor 61 is installed at the bottom of the crushing tank 41. The driving rod 62 and the driving motor 61 are connected by magnetic coupling. The driving rod 62 is provided with a crushing structure and a wall scraping structure. The crushing structure and the wall scraping structure cooperate with each other. The driving rod 62 is provided with a bidirectional threaded groove.

[0047] When the crushing component 4 of this device is in use, after the milk powder in the collection hopper enters the crushing tank 41, the drive motor 61 starts to run, transmitting power to the drive rod 62 through magnetic coupling. This ensures the sealing of the inside of the crushing tank 41 and prevents external contamination. The drive rod 62 rotates under the drive of the drive motor 61, and the bidirectional threaded grooves on its surface allow the milk powder inside the crushing tank 41 to tumble up and down, enhancing the crushing effect. The crushing structure first performs preliminary crushing of the milk powder entering the crushing tank 41, breaking up larger lumps. Meanwhile, the scraping structure closely adheres to the inner wall of the crushing tank 41. As the drive rod 62 rotates, the scraping structure can scrape off the milk powder adhering to the tank wall, preventing milk powder residue lumps and ensuring thorough crushing and cleanliness inside the tank. The crushing structure and the scraping structure work together, driven by the drive rod 62, to perform all-round, no-dead-angle crushing of the milk powder, making the milk powder particles more uniform and fine, further improving the quality of the goat milk powder.

[0048] like Figure 6 and Figure 9 As shown in this embodiment, specifically, the crushing structure includes a plurality of crushing rods 42, which are equidistantly installed at the bottom of the drive rod 62. A plurality of support rods are provided on the crushing rods 42. The wall scraping structure includes a mating ring 43 and a wall scraping ring 44. A bidirectional threaded groove is provided in the mating ring 43. The mating ring 43 is connected to the drive rod 62 in a transmission manner. The wall scraping ring 44 is in contact with the inner wall of the crushing tank 41. The mating ring 43 and the wall scraping ring 44 are fixed by a plurality of fixing rods. A plurality of scraper blades 45 are respectively provided on the side of the wall scraping ring 44 that is in contact with the inner wall of the crushing tank 41.

[0049] When the crushing and scraping structures are in use, the bidirectional threaded groove on the surface of the drive rod 62 engages with the bidirectional threaded groove in the mating ring 43, causing the mating ring 43 to reciprocate up and down along the axial direction of the drive rod 62. The mating ring 43 is connected to the scraping ring 44 via a fixed rod, so the scraping ring 44 also moves up and down accordingly. Several scrapers 45 on the side of the scraping ring 44 that contacts the inner wall of the crushing tank 41 can completely scrape off the milk powder adhering to different heights on the tank wall during the up and down movement. At the same time, the crushing rods 42, which are equidistantly installed at the bottom of the drive rod 62, move synchronously with the drive rod 62. The rotating crushing rod 42 has several support rods that cut and impact the milk powder, achieving initial crushing. As the cooperating ring 43 drives the scraping ring 44 to move up and down, the scraper 45 can not only scrape off the milk powder, but also stir the milk powder of different layers in the can, causing the milk powder to continuously gather towards the crushing rod 42 and the movement area of ​​the support rods. This increases the contact probability and the intensity of the action between the crushing rod 42 and the milk powder. The synergistic effect of the support rods and the scraper 45 breaks up large clumps of milk powder on the one hand, and prevents milk powder from accumulating on the can wall on the other hand, ensuring that all milk powder can be fully crushed, and finally obtaining goat milk powder with uniform particles.

[0050] like Figure 9 As shown, in this embodiment, specifically, the tilting direction of several scrapers 45 is matched with the moving direction of the mating ring 43;

[0051] When the mating ring 43 moves downward or upward along the drive rod 62: the scraper 45 on the scraper ring 44 can scrape off the milk powder on the inner wall of the crushing tank 41;

[0052] Therefore, during use, when the mating ring 43 moves downward along the drive rod 62, the tilt direction of the scraper 45 matches the downward movement trend. At this time, the upper surface of the scraper 45 can closely adhere to the inner wall of the pulverizing tank 41, scraping the milk powder adhering to the inner wall and located at a higher position downward. Conversely, when the mating ring 43 moves upward along the drive rod 62, the tilt direction of the scraper 45 matches the upward movement trend, and the lower surface of the scraper 45 comes into close contact with the inner wall, thereby scraping up the milk powder remaining at a lower position on the inner wall. This mechanism, combined with the mating ring 43... The inclined design of the scraper 45, which is adapted to the direction of movement, ensures that the scraper 45 always acts at the optimal angle on the inner wall of the grinding tank 41 during the entire process of the scraper ring 44's up-and-down reciprocating motion. Whether moving up or down, it can ensure efficient and thorough scraping of milk powder at different heights and positions on the inner wall, effectively avoiding milk powder residue and dirt accumulation on the tank wall, ensuring the cleanliness of the inside of the grinding tank 41, and also allowing the scraped milk powder to enter the grinding area for further processing in a timely manner, improving the overall grinding efficiency and the uniformity of the milk powder.

[0053] like Figures 6-7As shown, in this embodiment, specifically, the drying unit 3 includes a plurality of heating devices 31 and a temperature sensor. The heating devices 31 are equidistantly arranged on the side of the support plate 21, and the temperature sensor cooperates with the heating devices 31.

[0054] During operation, the temperature sensor monitors the ambient temperature around the support plate 21 in real time and feeds the temperature signal back to the control system. When the temperature is detected to be lower than the set low-temperature drying threshold, the control system automatically starts the heating device 31. The heating device 31 starts working and releases heat, raising the air temperature around the support plate 21 through heat transfer, providing a suitable low-temperature hot air environment for drying concentrated goat milk. When the temperature sensor detects that the ambient temperature reaches or exceeds the set value, the control system controls the heating device 31 to reduce its power or stop working to avoid excessively high temperatures that could damage the nutrients in the goat milk. Several heating devices 31 are equidistantly arranged on the side of the support plate 21, ensuring uniform temperature distribution in all areas of the support plate 21. This ensures that the goat milk is heated evenly during the drying process, avoiding local overheating or insufficient drying, thus guaranteeing the stable quality of the milk powder. The precise coordination between the temperature sensor and the heating device 31 enables real-time regulation and precise control of the drying temperature, providing a reliable temperature guarantee for the low-temperature drying of goat milk.

[0055] like Figures 1-4 As shown, in this embodiment, specifically, the concentration component 1 includes a concentration tank 11 and a vacuum pump 12. A heating unit is provided in the jacket of the concentration tank 11, a feed pump is provided at the output end of the concentration tank 11, a feed pipe is provided at the output end of the feed pump, and the vacuum pump 12 is connected to the concentration tank 11.

[0056] In the pretreatment of goat milk, the concentration component 1 first introduces fresh goat milk into the concentration tank 11. Then, the vacuum pump 12 is activated to evacuate the inside of the concentration tank 11, reducing the internal pressure and thus lowering the boiling point of the goat milk. This achieves low-temperature concentration, preventing high temperatures from damaging the nutritional components of the goat milk. Simultaneously, the heating unit inside the jacket of the concentration tank 11 starts working, transferring heat to the goat milk through the jacket to provide the energy needed for the evaporation of water from the goat milk. Under the combined action of heating and vacuum, the water in the goat milk gradually evaporates. As the concentration process progresses, the concentration of the goat milk continuously increases. When the set appropriate concentration is reached, the feed pump starts, transporting the concentrated goat milk in the concentration tank 11 to the subsequent carrier component 2 through the feed pipe. The continuous operation of the vacuum pump 12 ensures that the concentration process is carried out efficiently in a low-temperature environment. The heating unit, by precisely controlling the heating amount and cooperating with the vacuum pump 12 to adjust the vacuum level inside the tank, achieves precise control over the concentration rate and final concentration of the goat milk. This provides raw materials of suitable concentration for the subsequent low-temperature drying process, further ensuring the quality of the goat milk powder.

[0057] like Figures 1-4As shown, in this embodiment, specifically, a driving device is installed above the concentration tank 11, and a stirring assembly 7 is provided inside the concentration tank 11. The stirring assembly 7 includes a stirring rod 71, a plurality of support rods are provided on the stirring rod 71, and a plurality of auxiliary rods are installed on the other end of the support rods through bearings.

[0058] During the concentration process, the drive unit rotates the stirring rod 71 inside the concentration tank 11. The support rod on the stirring rod 71 rotates synchronously with it, stirring the goat milk in the tank. This ensures that the goat milk is heated evenly and avoids local overheating that could lead to nutrient loss. At the same time, several auxiliary rods mounted on the other end of the support rod via bearings rotate under the resistance of the goat milk. The rotation of the auxiliary rods further enhances the stirring effect on the goat milk, fully agitating the goat milk at the bottom and edge of the concentration tank 11. This prevents the goat milk from settling at the bottom of the tank or causing uneven concentration. This design of the stirring component 7, through the combination of the revolution of the stirring rod 71 and the rotation of the auxiliary rods, forms a multi-dimensional stirring motion. This greatly increases the contact area between the goat milk and heat and the mixing efficiency, accelerates the evaporation of water, shortens the concentration time, and ensures the uniformity of the concentration of the goat milk after concentration. This lays a good foundation for the uniform formation of the milk powder thin layer in the subsequent drying process.

[0059] like Figures 1-2 and Figure 5 As shown, in this embodiment, the drying device specifically includes a housing 8. Inside the housing 8, there is a concentration component 1, a low-temperature drying component, a pulverizing component 4, and a controller 81. The controller 81 is electrically connected to the concentration component 1, the low-temperature drying component, and the pulverizing component 4 via wires. Outside the housing 8, there is a control panel, which is electrically connected to the controller 81.

[0060] The enclosure 8 provides a closed environment, isolating external interference and ensuring clean and stable production. The controller 81 connects to each component through wires to achieve centralized control. Operators set parameters through an external control panel. The controller 81 adjusts the operating parameters of processes such as concentration, drying, and pulverization according to preset programs and sensor signals to achieve automated production, improve efficiency and product quality consistency, and also has abnormal alarm and protection functions.

[0061] like Figures 1-9 As shown, in this embodiment, the drying method specifically includes the following steps: S1, introducing goat milk into the concentration component;

[0062] S2. The concentrated goat milk is dried using a low-temperature drying unit.

[0063] S3. The crushing component crushes the dried goat milk blocks.

[0064] like Figures 1-9As shown, in this embodiment, specifically, S1 includes S11, a concentration component that concentrates goat milk to 1 / 4 of its original volume;

[0065] S2 includes S21, where the concentrated goat milk is first evenly sprayed onto the support plate;

[0066] S22. The drying unit dries the goat milk on the support plate at a low temperature.

[0067] Working Principle: When using this device, the sheep milk is first pre-treated by the concentration component 1, concentrating it to a suitable concentration. Then, it is evenly conveyed to each support plate 21 through the feeding pipe. At this time, the adjustment component 5 starts to work, and the adjustment motor 51 drives the adjustment shaft to rotate, thereby adjusting the support plate 21 to a suitable tilt angle to ensure that the sheep milk can be evenly spread and flow slowly on the support plate 21. During the flow of sheep milk, the drying unit 3 continuously delivers low-temperature hot air to perform low-temperature drying treatment on the concentrated sheep milk on the support plate 21. As drying proceeds, the moisture in the sheep milk gradually evaporates, forming a thin layer of pre-dried milk powder. When the milk powder layer moves to the end of the support plate 21, it will fall into the collection hopper at the bottom. After the collection hopper collects a certain amount of milk powder, the drive component 6 starts, driving the crushing component 4 to crush the milk powder, breaking the clumps of milk powder into uniform powder, and finally obtaining high-quality sheep milk powder. The whole process realizes continuous production from sheep milk concentration, low-temperature drying to milk powder crushing, effectively ensuring the nutritional components and quality of sheep milk powder.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
