A one-button start function, coupled with pre-set freeze-drying recipes for various food categories, allows for quick and easy operation without requiring specialized knowledge. It also supports preset constant temperature heating and custom parameter settings to meet diverse needs, from daily storage to professional production. For fresh ingredients, cooked foods, and pet food, it enables rapid freeze-drying preservation, precisely locking in nutrition and flavor. Its core performance highlights are particularly noteworthy: operating noise of single phase machine is strictly below the environmental standards for residential areas, ensuring a quiet and undisturbed environment; it adopts in-situ refrigeration technology, eliminating the need for an additional refrigerator, allowing fresh ingredients to be placed directly into the freeze-drying process; its energy-optimized design makes it more economical, with most models requiring only single-phase power, and only large-capacity models available with three-phase power, effectively reducing operating costs.
