How Much Does It Cost to Run a Freeze Dryer? Power & Operating Costs

How Much Does It Cost to Run a Harvest Right Freeze Dryer?

One of the most common questions from people considering a freeze dryer is what the ongoing operating costs look like. Here's a detailed breakdown.

**Electricity Use by Model**

- **Small and Medium Freeze Dryers:** Draw about 13–15 amps at peak, averaging closer to 9–11 amps during operation (roughly 990–1,210 watts per hour). Estimated operating cost: approximately $1.25–$2.80 per batch depending on local electricity rates. Requires a dedicated 15-amp circuit.

- **Large Freeze Dryer:** Draws about 13 amps at peak (approximately 1,500 watts per hour). Estimated operating cost: approximately $2.00–$3.00 per batch. Requires a dedicated 15-amp circuit.

- **X-Large Freeze Dryer:** Draws about 18 amps at peak, averaging around 15 amps (roughly 1,700 watts per hour). Estimated operating cost: approximately $4.00 per batch. Requires a dedicated 20-amp circuit.

**What Affects Electricity Cost?**

Batch time varies by food type. Dense foods, high-sugar items like pineapple, or warmer room temperatures can extend cycle time and increase total energy use. Most batches run between 13 and 35 hours, though candy can finish in just a few hours.

**Is Freeze Drying Worth It Financially?**

Many Harvest Right owners find freeze drying economical when considered against:

- Food waste prevented (the average family throws away hundreds of dollars of food each year)

- Cost of specialty freeze dried foods purchased commercially (which are typically very expensive per serving)

- Value of preserving homegrown or bulk-purchased food that would otherwise spoil

Over time, reducing waste and preserving bulk purchases can add up to significant savings.
