Harvest Right Pharmaceutical Large 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 Large model can process 12-14 lbs of wet material per cycle across its eight stainless steel trays (10.25 sq ft total tray space). This translates to approximately 3-3.5 lbs of finished dry product, depending on the initial moisture content. This is the highest capacity in the Pharmaceutical line, making it ideal for commercial-scale operations.

The Large Pharmaceutical model operates on standard 110V household power but requires an included adapter for proper connection. A dedicated 20-amp circuit is recommended for optimal performance. While it uses standard voltage, the adapter ensures the unit receives the correct power configuration for its larger capacity and ice chamber.

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. For high-volume commercial operations using the Large model, many users find the oil-free pump upgrade worthwhile for reduced downtime.

The Large Pharmaceutical Freeze Dryer measures 30.75" tall x 20.25" wide x 23.75" deep and weighs 161 lbs. This is the largest unit in the Pharmaceutical line, so ensure you have adequate space with proper ventilation around all sides. The larger footprint accommodates the 6-liter ice capacity and eight trays needed for maximum processing volume.

The Large model offers the highest capacity in the Pharmaceutical line with 8 trays (10.25 sq ft) and 12-14 lbs wet capacity, compared to the Medium's 7 trays (6.5 sq ft, 7-9 lbs) and Small's 5 trays (3.75 sq ft, 3.75-5 lbs). It also has the largest ice capacity at 6 liters. This makes it ideal for commercial operations, bulk processing, or serious botanical preservation work where maximizing throughput is essential.

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.

Absolutely. The Large Pharmaceutical Freeze Dryer is designed for commercial-scale operations. With its 12-14 lb wet capacity per batch and ability to produce 3-3.5 lbs of finished product every 20-24 hours, it's ideal for botanical processing businesses, pharmaceutical operations, or any commercial application requiring consistent, high-volume freeze-drying with premium quality results.
