Harvest Right [5-Tray] Medium Pro Home Freeze Dryer w/ Mylar Kit

The Medium Pro uses a three-stage process: food is frozen to -40°F, then a vacuum pump creates low pressure so ice sublimates directly to vapor — bypassing the liquid phase entirely. This removes 98% of moisture while leaving cellular structure, flavor, and nutrients intact. Sealed in Mylar bags with oxygen absorbers, the result stores for up to 25 years.

Yes. At 10–15 lbs of fresh food and 2–3.5 gallons of finished product per batch, the Medium Pro handles weekly preservation runs for families of 4–6 comfortably. Its 29" × 19" × 25" footprint fits in most kitchens and offers a meaningful capacity step up from the Small without requiring the space or power of the Large.

Most cycles complete in 20–40 hours depending on food type, moisture content, and slice thickness. Dense, high-moisture foods like whole fruits take longer than pre-cooked meals or thin slices. The unit runs automatically and alerts you when the batch is done, so there's no need to monitor it.

The included Premier pump needs an oil change every 20–25 batches. The process takes about two minutes: drain the old oil, swap the filter, and add fresh oil. If you'd prefer zero maintenance, the oil-free pump upgrade eliminates all upkeep while delivering the same reliable performance.

Both models share the same five food-grade stainless steel trays, digital controls, and processing performance. The difference is purely the exterior finish — powder-coated steel offers solid durability at a lower price point, while the stainless steel version provides a premium, rust-resistant exterior. The freeze-drying results are identical.

No — the Medium Pro runs on standard 110V household power with no dedicated circuit or special wiring required. It plugs into any standard outlet and is ready to use straight out of the box. Note that Harvest Right does not recommend using extension cords, as this can affect performance during operation.

The Medium Pro carries a full one-year warranty covering the entire unit and vacuum pump. Years two and three extend limited coverage to the sealed refrigeration system — compressor, condenser, evaporator, and tubing. Damage from misuse or neglect is excluded, and consumers cover diagnostic and transportation costs during the limited warranty period. Warranty applies to the continental U.S. 48 states.
