How Food Dehydrators Work

First and foremost, let's cover the basics. A food dehydrator circulates warm air around food using low heat and a fan to remove moisture over periods of time. The general temperature settings are going to range anywhere from 95°F to 165°F, dependent upon the type of food being dehydrated. The time needed to achieve this can be anywhere from 4-24 hours depending on the moisture content and the size of the food slice.

This would appear to be quite a long time to keep an electrical appliance turned on, which brings about the question of just how much energy does a food dehydrator use. Let's take a closer look.

How Much Energy Does a Food Dehydrator Use?

Food dehydrators come in different sizes and power ratings, generally between 300 and 1,000 watts. To give a rough comparison, an average kitchen oven uses about 2,000 to 5,000 watts per hour when it's turned on, meaning the food dehydrator is actually quite energy-efficient for extended cooking or preservation. But what does that have to do with actual cost?

Energy Consumption Breakdown

To make an accurate estimation of the cost of operating a food dehydrator, you'll have to understand a few key factors. First, there is power consumption: most food dehydrators used in households operate between 300 to 600 watts, while larger and more commercial models may go upwards of 1,000 watts or more. Operating time is another factor: food dehydration takes some time, usually falling anywhere between 6 to 24 hours, depending on the nature of the food and the quantity being dehydrated.

Cost of Electricity: This is essentially the biggest factor that influences operating costs for a food dehydrator; it's going to depend upon your local electricity rate in terms of how much you pay per hour for power consumption in the form of kilowatt-hours, or kWh.

Let me illustrate this better with an example:

Suppose that you have a food dehydrator rated at 500 watts, and you use it to dry fruits for 10 hours.

500 watts is equal to 0.5 kilowatts. So, if you run the dehydrator for 10 hours, you are using 5 kilowatt-hours (0.5 kw x 10 hours).

If your electricity rate is 12 cents per kilowatt-hour then the cost to run the dehydrator for 10 hours would be approximately 60 cents (5 kwh x $.12).

Even if you operate your food dehydrator for a full 24 hours, you are probably looking at less than US$2. That's far more cost-effective compared with running your oven for the same length of time.

Cost Comparison-Dehydrator vs Oven

One of the most common questions asked is why one would not just use an oven. The point of using an oven at a low temperature to dehydrate food is not an incorrect one; however, there are significant differences in price and performance.

Energy Efficiency: As explained, a regular oven consumes far more power than a dehydrator. If you plan on dehydrating food frequently, then the less powerful wattage of a dehydrator will help you save money eventually.

Consistency: Dehydrators ensure a consistent low temperature, whereas ovens, because of their inability to function under 170°F for any amount of time, often create inconsistent drying and sometimes even charring, which wastes the food and requires one to invest more money.

Operating Cost: Most ovens use an average of 2,500 watts and will cost you about 30 cents per hour at 12 cents per kWh. Dehydrators run between 6 and 12 cents per hour, depending on wattage applied and local electricity rates.

In the long term, a food dehydrator will not only be more economical but also efficient in drying food.

Actionable Tips to Lower Operating Costs

While food dehydrators are relatively inexpensive to operate, there are several ways you can make them even more energy-efficient:

1. Choose the Right Size for Your Needs

Dehydrators range in size from small, 4-tray models to larger units with up to 10 trays. While it is tempting to purchase one of the larger models, ensure that you select a size that will adequately suit the quantity of your typical batch. Operating a partially filled dehydrator is a waste of energy; therefore, choose a smaller model for small batches.

2. Pre-Slice Food to Reduce Drying Time

One obvious way to conserve energy is by dehydrating for less time. Simply cutting your food into uniform, thin slices will accomplish this. The thinner the slice, the faster it will dry. Faster dehydration times reduce the length of time your dehydrator needs to run.

3. Maximize Tray Space

This means trying to always have your dehydrator full. Running it with fewer trays is a waste of energy and money. Load up those trays for the biggest yield from each drying cycle.

4. Dehydrate in Off-Peak Hours

Some areas charge less for electricity during off-peak times. If this applies to your area, take advantage and use your dehydrator overnight or in other off-peak times to save on your energy bill.

5. Store Dehydrated Foods Properly

Save time by helping to extend the shelf life of your dehydrated foods with proper storage. Airtight containers and vacuum-sealed bags have no possibility of allowing moisture to get back in, meaning your dehydrated foods will last longer. This cuts down on having to repeatedly dehydrate the same foods, therefore saving you money over time.

Dehydrator Cost vs. Store-Bought Dried Foods

One of the most prevalent arguments about the cost-effectiveness of a dehydrator will relate to how much it costs to purchase pre-packaged dried foods. An example of this might be:

Dried Fruits: A small bag of store-bought dried mango or apple chips can range, depending on branding and packaging, anywhere from $4 to $8.

Homemade Dried Fruits: You can make dried mango yourself with a food dehydrator for less than half the price of the store-bought variety. For example, fresh mangoes cost about $2 apiece, and a batch will yield enough dried slices to rival a store-bought bag, all for under $1 worth of electricity.

Savings are even bigger if you dehydrate produce in bulk-especially if you grow your own fruits and vegetables or purchase them when they are in season from a farmer's market.

Conclusion: Are Food Dehydrators Expensive to Run?

The answer is a simple no. Food dehydrators have very low energy consumption, and compared to the rest of your kitchen appliances, like your oven, this device does not consume that much power. Just a few cents per hour, food dehydrators are not only an inexpensive way to preserve foods, but also a means to invest in healthy, additive-free snacks. With a few simple tricks, like preslicing food items to be dehydrated, loading the trays full, and running them when off-peak hours are available, you can save more in operating costs.

So stop the quivering about electricity costs and invest in that food dehydrator today, knowing it is relatively inexpensive and eventually will pay for itself through savings in electricity and preservation of food.

Imagine crafting delicious homemade jerky, dried fruits, and vegetable chips right in your own home.
