What is freeze drying, and how does it work?

Freeze drying, or lyophilization, removes about 99% of water whilethe food stays frozen, turning ice directly into vapor under vacuum. That preserves structure, color, flavorand about97% of nutrients. A typical cycle runs 20 to40 hours.

How long does freeze-dried food really last?

Sealed properlyin high-barrier packagingwith oxygen absorbers,25+ years is realistic. Store it below70 degrees F(21 C], dark, and dry. After opening, expect about1 to3 weeks unless you reseal it well.

What is the difference between freeze dryingand dehydrating?

Dehydrating uses warm air, about140 F, which cooks the foodand leaves it leathery, removing about80% of water. Freeze drying uses cold, along with vacuum instead, removing about99% of water whilekeeping texture, colorand far more nutrients, and enabling decades of shelf life.

What foods can be freeze-dried?

Fruits, vegetables, full meals, eggs, dairyand even candy freeze dry beautifully. Very high-fat foods like avocado, oilsand fatty cheeses can go rancid, so we usually keep those fresh. We guide you on prep for the trickier items.

How much does professional freeze drying cost?

We price by the tray plus by the batch, not flat per pound. Cycle time guides pricing. For comparison, a home machine runs about two thousand five hundred to five thousand dollars, plus dozens of hours of your time. Cycles run twenty to forty hours. Send us your food plus quantities for a clear quote.

Should I buy my own freeze dryeror use a service?

At steady, high volume, owning a machine can pay back in about1 to3 years. For low, seasonal or testing volumes, a service turns fixed costs into per-batch costsand lets you validate products before investing. Many businesses start with a service, then buy.

How should I package freeze-dried products for retail?

Use high-barrier Mylar, roughly three to seven mil, plus oxygen absorbers, then heat-seal each pouch. Block oxygen, moisture, light, heat, the four enemies. For longer storage, consider a nitrogen flush; clear labels carry storage plus best-before info.

Ice capacity

40 lb MANUFACTURER SPEC

The manufacturer states a 40 lb ice capacity. Practical capacity per batch is not published; it depends on the food, preparation, loading and workflow. WeFreezeDryIt has not yet published a documented practical capacity figure for its own Mega.

Practical capacity per batch depends on the food, how it is prepared and loaded, and the workflow around the machine. This site has not documented a tested practical capacity for this model, so practical-capacity fields are Not Published rather than guessed. Practical capacity is not the same as the manufacturer's rated or ice capacity.

Total tray area

Not calculable: tray dimensions are not published

NOT PUBLISHED

Total tray area cannot be calculated without published tray dimensions. See the tray-area comparison guide for why pound capacity and tray area are different numbers. Pounds per batch and tray area measure different things: fruit slices, candy and herbs are often limited more by tray area than wet weight, while purees and liquids are limited by tray depth and surface. See the tray-area comparison guide.

Oil type

Not published

NOT PUBLISHED

The manufacturer lists the Mega unit with an included industrial pump. The oil type and maintenance rhythm come from the pump manufacturer's documentation.

Oil-sealed pumps use vacuum oil with its own maintenance rhythm; oil-free pumps change the maintenance but do not remove it. See the pump comparison and the oil versus oil-free guide for the general tradeoffs.

Electrical

Not published NOT PUBLISHED Electrical requirements are not published here. Confirm the required circuit for your region with the manufacturer before purchase.

Does the model have multiple electrical options? Confirm the correct option for your region with the manufacturer. Never assume a country-specific standard: household circuits, higher-amperage circuits, 220/240 V and commercial power differ by country and by machine.

Operating Environment

Not published NOT PUBLISHED Recommended room temperature and clearances are not published for this model. Give the machine and its industrial pump room to breathe.

Recommended room temperature and clearance values are shown only where the manufacturer specifies them. Room temperature, ventilation and humidity matter most in warm tropical climates, and the room-requirements guide covers heat, air conditioning and pump exhaust without inventing figures.

Maintenance

Follow the owner's manual and the pump manufacturer's maintenance program. The industrial pump is a separate machine with its own oil and service requirements.

A maintenance schedule, vacuum pump oil guidance and cleaning routines apply to every machine; follow your manual and the pump manufacturer's program. Never open sealed refrigeration circuits; escalate to qualified service personnel.

Warranty & Support

Warranty terms are published by the manufacturer at the point of sale and can change. Confirm current terms directly with StayFresh. NOT PUBLISHED

Warranty duration, parts coverage, phone and email support, service network and replacement parts differ by brand and change over time. The warranty and support page compares the current published facts without assigning support-quality scores.
