Feature & Benefits

• Convenience of 4-tray dryer in a table top unit. Large capacity — capable of freeze drying as much as a gallon or two of material (6 to 10 lbs when wet).
• Full-color, touch-screen display.
• 4-liter ice condensing capacity.
• Operation allows for recipe customization (up to 10 Thermal Treatment and 12 Drying steps).
• Control of the rate of freeze. This means that the rate of freeze can be speeded up or slowed down.
• Control of the ultimate final freeze temperature.
• Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
• Control of the shelf temperature during the dry cycle. This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
• The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.
• The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
• Provides ongoing, real-time display of pressure and temperature.
• The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an ethernet cable.

FAQs

Which Freeze Dryer is right for me?

Small Freeze Dryer:
- Capacity of each batch is a 6 to 10 lbs. of fresh food
- In a year, one can freeze dry up to 1,800 lbs. or more of food

Medium Freeze Dryer:
- Capacity of each batch is 10 to 15 lbs. of fresh food
- In a year, one can easily freeze dry up to 3,000 lbs. of food

Large Freeze Dryer:
- Capacity of each batch is 18 to 27 lbs. of fresh food

X-Large Freeze Dryer:
- Capacity of each batch is around 40 to 50 lbs. of fresh food
- In a year, one can easily freeze dry up to 10,000 lbs. of food

How does the freeze dryer work?

The entire process is automatic.

1. Raw or cooked foods are placed in the freeze dryer where they are frozen to between -30 degrees and -50 degrees Fahrenheit.

2. Once frozen, the freeze dryer creates a vacuum in the food chamber.

3. As the food is gradually warmed, the water turns to vapor and evaporates out of the food (sublimation).

4. When dry, the freeze dryer notifies the user that the process is complete by sounding an audible beep.

5. You can then remove the freeze dried food from the dryer and place it in vacuum-sealed containers that are moisture and oxygen proof (preferably a mylar pouch or a can) to ensure freshness until opened.

6. When water is added to the food, it regains its original fresh flavor, aroma, texture, and appearance!

What type of food can be freeze dried?

You truly can freeze-dry almost anything. All kinds of fruits, vegetables and meats taste wonderful when freeze dried. That includes things like tomatoes, apples, bananas, strawberries, peaches, green beans, peppers, onions, potatoes, spinach, shrimp, pork, beef, turkey and even ice cream.

Your favorite meals that include meat may be easily freeze dried. Foods like lasagna, rice dishes, cheese macaroni, chili, beef stew, chicken a la king, casseroles, shrimp, lobster, pulled pork, pasta sauces or scrambled eggs are perfect for this process.

You will find that it is a delight to experiment with different foods and meals in your freeze dryer. A great way to start is by picking meals that are already favorites in your home.

How much food can be freeze dried with each batch?

Small
6-10 lbs. of fresh food will fit in our small freeze dryer. It is not uncommon for customers to freeze dry up to 1,800 lbs. of fresh food in just 1 year. Tray space= 434 sq. inches

Medium
10-15 pounds of fresh food will fit in our medium size freeze dryer. It is not uncommon for customers to freeze dry up to 3,000 lbs. of fresh food in just 1 year. Tray space= 675 sq. inches

Large
18-27 pounds of fresh food will fit in our large freeze dryer. It is not uncommon for customers to freeze dry up to 5,000 lbs. of fresh food in just 1 year. Tray space= 1,107 sq. inches

X-Large
40-50 pounds of fresh food will fit in our X-Large freeze dryer. It is not uncommon for customers to freeze dry up to up to 10,000 pounds of fresh food in just 1 year. Tray space= 2,251 sq. inches

How long does it take to freeze dry each batch?

It typically takes between 20 to 40 hours to complete the process. Food type and quantity will affect the freeze-dry cycle. Things like meat, peas and corn dry quickly, while squash and watermelon can take longer. The thickness of the food slices will affect the cycle time too.

Most importantly, your machine senses when the food is ready (alerting you with a beep) so you don’t have to guess when to stop the freeze-dry cycle.

Is it ok to freeze things prior to placing in the freeze dryer?

Yes! It is a great idea to put frozen products into your freeze dryer. Your machine will accept pre-frozen foods and cool them even further, to around -40 degrees F.

What components make up a freeze dryer?

The freeze dryer unit itself as well as a high-quality vacuum pump that sits outside the freeze dryer.

What maintenance is required for a freeze dryer?

The freeze dryer itself requires little to no maintenance. However, as shown below, all freeze dryers come with a high quality vacuum pump, which requires some maintenance, mainly adding and draining oil.

The vacuum pump comes equipped with an initial supply of oil. There are 3 cups of oil in a vacuum pump that need to be changed regularly to keep a freeze dryer running efficiently. This is a simple process, and requires little effort.

Each freeze dryer also includes a stand-alone oil filter. The filter cleans the oil and allows you to keep reusing your oil as if it were new. Using filtered oil in each batch is a great way to save money and be more eco-friendly, while also helping your vacuum pump perform as efficiently as possible

What type of power do the freeze dryers use? How much will it cost to run?
