The Blue Alpine Large Freeze Dryer is a home freeze dryer built for volume: five 18x13-inch stainless trays hold up to 25 lbs or 2 gallons per cycle, roughly 16 lbs per 24 hours. Its 1/2 HP Cubigel compressor and 1 HP rotary vane pump (10-12 CFM) push typical cycles to 12-20 hours, faster than many home units that run a day or more. It needs a dedicated 120V, 20A circuit and draws up to 2040W, and at 130 lbs with the pump it is a permanent-floor appliance rather than a countertop one. It suits gardeners, hunters and bulk buyers who preserve in large batches; smaller households will find the Medium model's capacity enough.
