1. Initial screening of debris at the source: A special high-efficiency pre-sorting device is used. The device is equipped with a sensitive foreign body sensor probe, which can quickly detect and accurately pick out debris such as leaves and thread ends mixed in the down raw materials, ensuring the basic purity of the down raw materials, opening a good situation for the subsequent complicated processing procedures, and effectively reducing the subsequent processing costs.
2. Powerful vacuuming and dust removal: With the help of professional-grade powerful vacuuming equipment, this equipment is equipped with multiple layers of high-density filters. For the down after the initial screening, it uses super suction to absorb dust in all directions in a fully enclosed vacuuming channel. After this process, the dust in the down is greatly removed, and the cleaning requirements are initially met, creating a clean environment for subsequent processes and reducing secondary processing caused by dust residue.
3. Intelligent down sorting: Using the independently developed intelligent down sorting system, the system combines advanced wind screening and precise weight recognition technology. According to the density, fluffiness and morphological characteristics of the down itself, the vacuumed down is accurately separated into down, feathers of different sizes and various wing stems, creating conditions for subsequent differentiated fine processing and improving the rational utilization rate of down resources.
4. Efficient cleaning and descaling: In the specially customized large-capacity wool washing equipment, a professional down cleaning agent that has been strictly tested and cost-effective is added. The cleaning agent adopts an efficient decontamination formula, which can quickly dissolve and remove grease, stains and odors on the surface of the down during the cleaning process. At the same time, with its mild chemical properties, it ensures that the down fibers are not damaged, allowing the down to restore its natural cleanliness, and the cleaning cost is controlled within a reasonable range.
5. High-speed centrifugal drying: Using high-speed centrifugal dehydration equipment, by scientifically setting the speed and time, a large amount of water in the washed down can be quickly thrown out in a short time. The unique liner design of the equipment can ensure that the down remains fluffy during dehydration, reduce fiber entanglement, save a lot of time and energy consumption for subsequent drying, and improve overall processing efficiency.
6. High-temperature rapid drying: Transfer to the high-temperature hair drying equipment designed specifically for hotel down quilt fillings. The equipment uses advanced thermal cycle technology to quickly and evenly dry the dehydrated down at a high temperature (60℃ - 80℃). During the drying process, the natural bactericidal properties of high temperature are used to simultaneously achieve deep deodorization and thorough disinfection to ensure that the down is clean and sterile, meeting the hotel's strict requirements for hygiene, and the drying efficiency is high, reducing the cost increase caused by the processing time.
7. Air-cooled secondary dust removal: Use intelligent air-cooled cooling equipment to quickly cool down the dried down. During the cooling process, the multi-layer fine filter inside the equipment will capture and filter out the fine impurities and dust that may remain, further improving the cleanliness of the down, while keeping the down fluffy, ensuring the stability of the quality of the down, and reducing the difficulty of later care caused by impurities.
8. Strict quality verification: For all kinds of down products that have completed the cooling process, we strictly refer to the high standards and cost-effective requirements of the hotel industry for comprehensive and detailed quality inspections. The test content includes the core indicators of down fluffiness, cleanliness, fat content, microbial content, etc., to ensure that each batch of down can meet the hotel's quality requirements for general use and easy care in all seasons, and take into account cost-effectiveness while ensuring quality.
9. Convenient packaging and storage: For down that has passed the test, strong, durable and cost-effective packaging materials are used according to different varieties and specifications, and automated packaging equipment is used for efficient classification and packaging. After packaging, the products are properly packaged and stored in a well-ventilated environment with suitable temperature and humidity to ensure that the down is always in good condition during storage and transportation, providing the hotel with high-quality down quilt fillings that are easy to care for, suitable for all seasons and cost-effective.
