Description

Technical Field

[0001] This utility model relates to the field of milk powder production technology, specifically a high-efficiency dryer for drying milk powder. Background Technology

[0002] Milk powder production includes the following steps: preparing and quality-checking raw milk, filtering and pasteurizing, and then removing some moisture by evaporation concentration. Next, the concentrated milk is spray-dried into powder, sieved and mixed with additives, and finally packaged, sealed, and subjected to quality testing and storage. An existing drying device for milk powder production (publication number: CN216169987U) has exhibited at least the following defects during use:

[0003] 1. The inability to quickly adjust pressure means that when processing different materials or with different process requirements, it is necessary to stop the machine to adjust the pressure. This leads to increased downtime and waiting time in the production process, reducing production efficiency. Stopping to adjust pressure not only wastes time but may also increase energy consumption and raw material losses, thereby increasing production costs. Instability or untimely adjustment of pressure during the pressing process may lead to fluctuations in product quality. Especially for products with high pressing pressure requirements, such fluctuations may affect product uniformity and the achievement of quality standards. Therefore, a high-efficiency dryer for drying milk powder is needed.

[0004] 2. Milk powder adhering to the walls of the drying equipment increases the difficulty of cleaning, requiring more frequent and thorough cleaning, thus increasing the workload of operators and cleaning costs. Frequent cleaning and accumulated milk powder may cause wear and tear on the inner walls of the equipment, shortening its lifespan. Frequent cleaning and maintenance due to milk powder adhering to the walls can cause production interruptions, affecting the continuity and output of the production line. Adherence to the walls may lead to more defective products, requiring reprocessing or scrapping, further reducing production efficiency. Therefore, a dryer that prevents milk powder from adhering to the walls is needed.

[0005] 3. Operators need to manually clean the equipment regularly, which will cause production interruptions, increase downtime and cleaning costs. Manual cleaning requires a lot of manpower and time, increasing labor intensity and maintenance costs. Milk powder residue on the inner walls of the equipment that is not thoroughly cleaned may cause cross-contamination of new batches of products, affecting product quality and safety. Residue may affect newly produced milk powder, leading to an increased product defect rate, requiring additional processing or scrapping. Therefore, a self-cleaning dryer is needed.

[0026] Example

[0027] Please see Figure 1-4 The present invention provides the following technical solution:

[0028] A high-efficiency milk powder dryer includes a machine shell 1, a support ring 2 installed on the outer side of the machine shell 1, a support rod 3 installed at the bottom of the support ring 2, a cover 4 installed on the machine shell 1, several hot air outlets 9 vertically installed on the inner wall of the machine shell 1, the hot air outlets 9 being connected to a hot air pipe 8 to the outside, an atomizing nozzle 5 installed inside the cover 4, the atomizing nozzle 5 being connected to a raw liquid pipe 6, and an outlet 7 provided at the bottom of the machine shell 1.

[0029] Specifically: the hot air duct 8 is a duct with different temperatures.

[0030] Specifically: The cover 4 is provided with a curved outlet 13, which is connected to the hot air pipe 8.

[0031] Specifically: Several high-pressure nozzles 12 are installed inside the cover 4. The high-pressure nozzles 12 are connected to the water inlet pipe 11, and the water inlet pipe 11 is connected to the water pump.

[0032] Specifically: A smart panel 10 is installed on the side of the machine casing 1, and the smart panel 10 is connected to the water pump, motor and power supply.

[0033] Specifically: the machine casing 1 and the cover 4 are connected by a screw thread.

[0034] In this embodiment, several hot air outlets 9 are vertically installed on the inner wall of the machine casing 1. These hot air outlets 9 are connected to external hot air pipes 8, which are pipes supplying hot air at different temperatures. Multiple hot air outlets 9 are vertically installed on the inner wall of the machine, evenly distributed from top to bottom. These hot air outlets 9 ensure that hot air circulates throughout the entire drying chamber, avoiding uneven drying caused by insufficient hot air in certain areas. Each hot air outlet 9 is connected to an independent hot air pipe 8, which can supply hot air at different temperatures. This design allows for heating and drying of milk powder particles at different locations at different temperatures. This vertically arranged multi-layered hot air outlet design ensures that hot air within the drying chamber evenly covers each layer of milk powder particles. Whether the milk powder is near the top or near the bottom, it receives uniform hot air, improving the overall drying efficiency and uniformity.

[0035] During the drying process, the eight hot air ducts can supply hot air at different temperatures. The top hot air outlet 9 supplies higher-temperature hot air to quickly evaporate a large amount of moisture, while the bottom hot air outlet 9 supplies lower-temperature hot air to prevent the milk powder from over-drying or burning in the later stages of drying. The drying process is usually divided into multiple stages, each requiring a different temperature. The initial stage requires a higher temperature to quickly remove most of the moisture, while subsequent stages require a lower temperature for fine drying to ensure that the final product's moisture content meets requirements. By adjusting the temperature of the eight hot air ducts, the most suitable drying temperature can be provided according to the actual needs of each drying stage, optimizing the entire drying process. Operators can set different temperature programs through the intelligent panel 10 to ensure that the most suitable temperature is provided at each drying stage, improving drying efficiency and reducing human error. The design of the eight hot air ducts with different temperatures can precisely control temperature changes during the drying process, preventing the milk powder from burning due to excessively high temperatures in the early stages of drying, and also preventing excessively high moisture content due to insufficient temperatures in the later stages of drying. This temperature control not only improves drying efficiency but also ensures product quality, avoiding product quality problems caused by improper drying.

[0036] In this embodiment, the cover 4 is provided with a curved outlet 13, which is connected to the hot air pipe 8. Several curved outlets 13 are designed inside the cover 4. The curved outlets 13 are connected to the hot air pipe 8 via pipes, and the hot air in the hot air pipe 8 enters the drying chamber through the curved outlets 13. The connection is sealed to prevent hot air leakage and temperature loss. The curved outlet 13 design creates a specific airflow path for the hot air entering the drying chamber, guiding the hot air through the bending angle to form a stable airflow covering the inner wall of the drying chamber. By adjusting the pressure and flow rate of the hot air, it is ensured that the hot air blows across the inner wall of the drying chamber at an appropriate speed. The high-speed airflow effectively prevents milk powder particles from adhering to the inner wall during the drying process. During the drying process, milk powder particles may adhere to the inner wall due to static electricity. The hot airflow guided by the curved outlet 13 can neutralize some of the static electricity, reducing the adhesion of the milk powder particles and thus preventing them from sticking to the wall. The design of the curved outlet 13 allows the hot air to be evenly distributed within the drying chamber, covering not only the milk powder particles but also the entire inner wall. In this way, any milk powder particles that may adhere will be blown away by the airflow. The continuous blowing action of hot air, especially during the critical stages of the drying process, can continuously remove milk powder particles that may adhere to the inner wall, ensuring that the interior of the drying chamber remains clean.

[0037] In this embodiment, several high-pressure nozzles 12 are installed inside the cover 4. These nozzles are connected to a water inlet pipe 11, which in turn is connected to a water pump. The high-pressure nozzles 12 are universal nozzles manufactured by Wenzhou Yike Electromechanical Equipment Co., Ltd. This product allows adjustment of the nozzle's installation angle and spray position, with an adjustment range of 45°. It features a precision-machined surface to ensure sealing and prevent leakage. The cleaning system can complete the cleaning process in a short time, reducing equipment downtime and improving production efficiency. Because of the high cleaning frequency and short time, continuous production can be achieved for longer periods, reducing production interruptions caused by manual cleaning. The automatic cleaning system reduces reliance on operators, lowers the frequency and intensity of manual cleaning, and saves labor costs. Regular automatic cleaning effectively prevents wear and corrosion caused by milk powder residue inside the equipment, extending its service life. The automatic cleaning system can quickly clean the inner wall of the equipment after each batch of production, preventing cross-contamination between different batches and ensuring product consistency and safety. Operators only need to start the cleaning program through the intelligent control panel, and the system will automatically complete the cleaning process; operation is simple and easy. The integrated design of the high-pressure nozzle 12 with the water inlet pipe 11 and water pump enables a highly automated cleaning process, requiring no manual intervention. The system can adjust the spraying time and water volume of the high-pressure nozzle 12 as needed, avoiding excessive water use and conserving cleaning resources. The high-pressure nozzle 12 generates a powerful water flow, quickly and effectively removing milk powder residue for superior cleaning results.

[0038] It should be noted that this utility model, as a high-efficiency dryer for drying milk powder, can precisely control the temperature changes during the drying process by installing several hot air outlets 9, preventing the milk powder from burning due to excessively high temperature in the early stage of drying, and also preventing excessive moisture content due to insufficient temperature in the later stage of drying; by installing curved outlets 13, it can ensure that the hot air blows on the inner wall of the drying chamber at an appropriate speed, which can effectively prevent milk powder particles from adhering to the inner wall during the drying process; by installing high-pressure nozzles 12, the cleaning process can be completed in a short time, reducing equipment downtime and improving production efficiency.
