The Dual-Compartment Sterilizer is an innovative solution for categorized sterilization of baby items, first developed in China. Its pioneering dual-compartment design separates the sterilization of baby bottles and toy clothing products, effectively preventing cross-contamination between different categories. The upper and lower compartments can be independently controlled, allowing for personalized sterilization programs tailored to the type of product, thus ensuring efficiency and energy savings. The device employs three sterilization technologies—six-sided three-dimensional UV irradiation, photo-catalyst, and high-temperature hot air—achieving a sterilization rate of up to 99.999%. Compared to its predecessor, the capacity has been increased to 30 liters, enabling the sterilization of more baby items at once and significantly improving the efficiency for parents in feeding their babies. Moreover, after the baby grows up, the device can also be used as a household kitchenware sterilizer, extending the product’s life cycle and reflecting the concept of sustainable development and environmental protection.
