Harvest Right Pharmaceutical Medium Freeze Dryer

The Pharmaceutical Freeze Dryer is specifically engineered for preserving delicate botanical and pharmaceutical compounds. It uses precise vacuum pressure and temperature control to maintain enzymes, terpenes, and active compounds without applying heat. This makes it ideal for herbs, oils, medicines, and other sensitive materials where potency and appearance must be preserved.

The Medium model can process 7-9 lbs of wet material per cycle across its seven stainless steel trays (6.5 sq ft total tray space). This translates to approximately 1.75-2.25 lbs of finished dry product, depending on the initial moisture content of your material. This makes it ideal for medium-scale operations that need more capacity than the Small model.

A complete freeze-dry cycle typically takes 20-24 hours, depending on the material being processed and its moisture content. The unit handles everything automatically once started, requiring minimal supervision during the process.

The included Premier pump offers excellent performance and requires oil changes every 20-25 batches (approximately 2 minutes per change). If you prefer a maintenance-free experience, the oil-free pump upgrade ($1495) eliminates all oil changes while maintaining reliable operation. Choose the oil-free option if you're processing frequently or want truly hands-off operation.

The Medium Pharmaceutical Freeze Dryer measures 28.5" tall x 18" wide x 21.25" deep and weighs 133 lbs. You'll need a stable surface with adequate ventilation around the unit. It operates on standard 110V household power with a dedicated 20-amp circuit recommended for optimal performance.

With the Premier oil pump, you'll need to change the oil every 20-25 batches (a simple 2-minute process). The freeze dryer chamber should be wiped clean between batches and periodically sanitized. The oil filter should be replaced as needed. If you upgrade to the oil-free pump, maintenance is virtually eliminated—just keep the unit clean and check door seals periodically.

Harvest Right includes a comprehensive 3-year warranty. The first year covers full parts and labor for the entire unit and vacuum pump. Years two and three provide limited warranty coverage specifically for the sealed refrigeration system (compressor, condenser, evaporator, and tubing). This warranty applies to the continental U.S. 48 states.

The Medium model sits between the Small (5 trays, 3.75-5 lbs capacity) and Large (8 trays, 12-14 lbs capacity). It's perfect for operations that have outgrown the Small model but don't need the full capacity of the Large. With 7 trays and 6.5 sq ft of tray space, it offers a significant capacity increase while maintaining a reasonable footprint and the same 110V power requirements.

Yes, the Medium Pharmaceutical Freeze Dryer is well-suited for small to medium-scale commercial operations. Its 7-9 lb wet capacity per batch makes it ideal for craft producers, boutique pharmaceutical operations, or botanical processing businesses. The stainless steel construction and precise controls ensure consistent, professional-grade results batch after batch.
