4kg/batch Stainless Steel Home Freeze Dryer with One-key Start and Clear Acrylic Door

Senova NovaDryer-JF400 redefines home freeze-drying speed and efficiency with its proprietary dual-stage vacuum rapid sublimation technology. Engineered for households that value both performance and sustainability, this 4Kg/batch freeze dryer completes food preservation cycles up to 30% faster than conventional home lyophilizers while consuming significantly less electricity. The JF400 achieves this breakthrough through an innovative two-phase vacuum system that accelerates moisture sublimation during the critical early drying stage, combined with an inverter-driven compressor that dynamically adjusts power output based on real-time thermal load demand. For busy families, meal-prep enthusiasts, and self-sufficiency advocates, the JF400 delivers professional-quality freeze-dried foods in less time and at lower operating cost.

At the heart of the JF400 is a food-grade SUS304 stainless steel chamber with four thermostatic heating trays, providing 0.33 m² of effective drying area. The dual-stage vacuum system first establishes a deep vacuum of 10 Pa to initiate rapid ice crystal sublimation, then modulates to an optimized mid-range vacuum level that maintains high sublimation rates while protecting delicate food structures from collapse. The inverter compressor operates across a variable speed range, ramping up cooling power during the initial freeze phase and dialing back during the secondary drying phase to minimize energy waste. Paired with the intuitive 4.3-inch color touchscreen interface featuring one-key smart programs, the JF400 makes fast, energy-conscious freeze drying accessible to users of all experience levels without sacrificing the nutritional quality or shelf stability of preserved foods.

• Dual-Stage Vacuum Rapid Sublimation: Proprietary two-phase vacuum technology accelerates the freeze-drying cycle by 30%, enabling batch completion in as little as 14 hours for many food types while preserving superior texture and nutritional integrity.
• Inverter Energy-Saving Compressor: Variable-speed compressor technology precisely matches cooling output to thermal demand, reducing electricity consumption by up to 25% compared to fixed-speed compressor systems and extending component service life.
• Deep -40°C Cold Trap: Enhanced refrigeration system achieves a minimum shelf temperature of -40°C, ensuring complete freezing of high-water-content foods and enabling effective processing of sugar-rich fruits that require lower eutectic temperatures.
• Food-Grade SUS304 Chamber: The entire product-contact zone including the drying chamber and four thermostatic trays is constructed from SUS304 stainless steel, providing corrosion resistance, effortless sanitation, and full food safety compliance.
• One-Key Optimized Programs: Pre-configured drying profiles automatically adjust the dual-stage vacuum timing, shelf temperature ramp rates, and inverter compressor speed for different food categories, delivering repeatable results with a single button press.
• Low Power Consumption: With an average operating consumption of just 0.75 kW/hr during a typical drying cycle, the EF400 is one of the most energy-conscious home freeze dryers in its capacity class, keeping long-term operating costs manageable.
• Rapid Defrost System: Integrated one-key automatic defrost clears the cold trap in minutes rather than hours, reducing downtime between consecutive batches and improving overall throughput for high-volume home preservation sessions.
• One-key start and defrost operation
• 4.3" color LCD touch screen interface
• Dual control modes (automatic and manual)
• Powder coated housing with 8 color options
