Freeze drying food at home is a revolutionary way to preserve food while retaining nutrients, flavors, and texture. But one of the most common questions is whether the cost of purchasing and maintaining a freeze dryer justifies the potential savings over time. In this post, we’ll break down the costs and savings associated with home freeze drying to help you decide if it’s worth the investment.
Understanding the Cost of Freeze Drying at Home
1. Initial Investment: Buying a Freeze Dryer
The upfront cost of a home freeze dryer is the biggest hurdle for most people. Here’s a rough breakdown of what you might expect to pay:
Small Freeze Dryer: $2,500 - $3,000
Medium Freeze Dryer: $3,500 - $4,000
Large Freeze Dryer: $4,500 - $5,500
You can also opt for additional features, like an oil-free vacuum pump, which adds about $1,500 to the total cost.
2. Accessories & Consumables
Mylar Bags & Oxygen Absorbers: $0.25 - $0.75 per bag/absorber combo.
Vacuum Sealer Bags: $0.10 - $0.50 per bag.
Storage Containers or Jars: $2 - $10 each (reusable).
Freeze Dryer Oil (for models with oil pumps): $15 - $25 per bottle, required for routine maintenance.
While these are ongoing costs, they’re relatively small compared to the initial equipment purchase.
3. Electricity Costs
Running a freeze dryer can be energy-intensive, as it typically operates for 20-40 hours per batch. The electricity cost varies by region, but on average:
Estimated electricity cost per batch: $1.50 - $3.00
Assuming you run a freeze dryer once a week, this adds about $75 - $150 to your annual electricity bill.
Calculating the Savings from Freeze Drying
1. Reduced Food Waste
The USDA estimates that an average family of four wastes about $1,500 in food each year. Freeze drying lets you preserve excess produce, leftover meals, and bulk purchases, significantly reducing food waste. If freeze drying cuts your food waste by even 50%, you’re looking at a potential savings of $750 annually.
2. Lower Grocery Costs by Buying in Bulk or Seasonally
Buying fruits, vegetables, and meats in bulk is much cheaper than buying smaller quantities regularly. Freeze drying allows you to purchase items in larger quantities when they’re on sale or in season, leading to substantial savings.
Example: A 10-lb bag of potatoes costs about $5, while freeze-dried potato flakes in a store might cost $20 for a 1-lb bag. Freeze drying at home results in a cost of around $8 (including energy and mylar bags), saving up to $12 per batch.
3. Preserving Garden Harvests
If you have a home garden, a freeze dryer allows you to preserve the excess produce that might otherwise spoil. For avid gardeners, this can result in significant savings:
Example: A typical tomato plant produces 10-20 lbs of tomatoes. At $2 per pound in the grocery store, this amounts to $20-$40 worth of tomatoes per plant. With multiple plants, a freeze dryer can preserve hundreds of dollars worth of produce.
4. Homemade Freeze-Dried Meals
Prepared freeze-dried meals can be expensive, often costing $8 - $12 per serving. Making your own freeze-dried meals at home brings the cost down to about $3 - $5 per serving, factoring in ingredients and electricity. If you replace one store-bought meal per week with a homemade version, you could save $250 - $500 annually.
5. Emergency Food Supply
Store-bought emergency food supplies can cost up to $3,000 for a year’s worth of freeze-dried meals. Creating your own emergency food supply can cut that cost in half, resulting in a savings of up to $1,500.
Cost vs. Savings Breakdown: Is It Worth It?
Let’s look at an estimated 5-year cost vs. savings comparison for a medium-sized freeze dryer:
Initial and Ongoing Costs Over 5 Years
Medium Freeze Dryer: $4,000
Accessories (Mylar bags, oxygen absorbers, etc.): $250/year x 5 = $1,250
Electricity Costs: $100/year x 5 = $500
Total Cost: $5,750
Potential Savings Over 5 Years
Reduced Food Waste: $750/year x 5 = $3,750
Bulk Buying/Garden Harvests: $500/year x 5 = $2,500
Homemade Freeze-Dried Meals: $400/year x 5 = $2,000
Emergency Food Supply Savings: $1,500 (one-time savings)
Total Savings: $9,750
Net Savings Over 5 Years
Total Savings: $9,750
Total Cost: $5,750
Net Savings: $4,000
Based on this breakdown, investing in a freeze dryer can pay off within 5 years, offering both savings and additional benefits like healthier, longer-lasting food storage.
Additional Considerations
Health Benefits: Freeze-drying retains up to 97% of the nutrients in food, providing a healthier alternative to canned or dehydrated food.
Emergency Preparedness: Having a personal stockpile of freeze-dried food can be invaluable during unexpected events, adding another layer of value.
Convenience: The ability to prepare meals ahead of time and have them shelf-stable is a major convenience for busy households.
While the initial cost of a home freeze dryer is significant, the potential savings from reduced food waste, bulk purchasing, homemade freeze-dried meals, and emergency preparedness can make it a worthwhile investment over time. If you’re serious about long-term food preservation, reducing food costs, and embracing a more sustainable lifestyle, a freeze dryer might be worth considering.
