Freeze Dry Food Machine for Home Use

The HFD-9 Freeze Dry Food Machine For Home Use is a high-capacity, food-grade freeze dryer designed to bridge the gap between residential convenience and industrial-level efficiency. Engineered with a robust 304 stainless steel chamber and a heavy-duty frame, this unit is built for long-term operational stability. It provides a significant freeze-drying area of 0.9m², distributed across 10 layers of precision-manufactured stainless steel trays. Each tray measures 200*425mm, supported by a 35mm shelf clearance that is scientifically optimized to facilitate efficient vapor escape during the primary and secondary drying phases. This configuration allows the HFD-9 to handle a substantial processing capacity of 12-14kg per batch, making it suitable for high-volume home preservation or small-scale commercial production.

From a technical standpoint, the HFD-9 Freeze Dry Food Machine For Home Use is powered by a 2300W refrigeration and vacuum system. The cold trap is designed to reach a stable temperature of -55℃, which is critical for the rapid immobilization of water molecules within the food matrix. The vacuum system is equally high-performing, achieving an ultimate vacuum level of less than 2Pa with a pumping rate of 2-4L/S. These parameters ensure that the sublimation process occurs under deep vacuum conditions, minimizing the risk of material "melt-back" and ensuring the final product remains porous and crisp. The unit's water capture capacity is rated at 12KG within a 24-hour window, providing sufficient headroom for high-moisture materials like succulent fruits or liquid-based foods.

The operation is managed via a PLC-based control system with a high-definition touchscreen. This interface allows users to switch between 7 pre-calibrated formulas for meat, fruit, candy, and other common materials, or utilize 20 customizable recipe slots for proprietary drying curves. The system integrates a material probe that provides real-time feedback on the core temperature of the samples, ensuring the cycle only progresses when the specific thermal criteria are met. Maintenance is simplified through an integrated defrost function and a transparent plexiglass door that allows for visual monitoring without breaking the vacuum seal. The HFD-9 operates at a noise level of ≤60dB and is air-cooled, requiring only a standard environment of 10-35℃ and a 220V/50HZ power supply (customizable to 110V or 380V).
