Can You Freeze Dry Without A Machine? – When you first learn how to freeze dry strawberries, you may wonder if the machine is absolutely necessary. Learning how to make freeze dried strawberries without the machine is a bit different. One of the most effective methods to freeze dry without use of a machine is using dry ice.
- To start, place your strawberries into a freezer bag and lay them at the bottom of a cooler that is twice as big as it needs to be.
- From there, place your dry ice in a one to one ratio pound for pound with the strawberries.
- Allow the dry ice to sit for twenty four hours until it has completely dissolved.
Immediately move the strawberries from the cooler into sealed containers for storage. Make sure you ventilate the cooler by drilling holes or otherwise allowing air to enter the cooler. The dry ice process will build up pressure inside the cooler, causing it to explode without proper ventilation.

How do you dry fruit without a machine?
No bulky dehydrator is needed to make dried fruit. (Hint: The key is low and slow.) Fresh fruit is great for satisfying that sweet tooth without grabbing a tempting candy bar, but if I have to eat one more apple I’m going to scream. I admit that I’m a bit bored with my daily apple in the afternoons, and I’ve been looking for something else I can nosh on that gives me more of a sensation of eating potato chips.
I started doing some Internet sleuthing and was quite intrigued with dried fruit. However, I have no desire to buy a huge food dehydrator machine because of the price tag and because I have nowhere to store it. So that left me to figure out how to make dried fruit in the oven. It’s really simple, and the best part is it helps me stay on track with my nutritional goals.
The dried fruit is also great on my morning yogurt (in place of granola) or my healthy steel-cut oatmeal, It’s perfect for snacking on in the middle of the day, and the kids love it in their lunch boxes. Here’s how to make dried fruit without a dehydrator.
ApplesStrawberriesKiwifruit1 Tbsp. Water1 Tbsp. Lemon Juice
Instructions Clean all the fruit. Core and slice the apples and strawberries. I dried 2 apples, 6 strawberries, and 2 kiwis. Use a mandoline slicer to slice the apple into equally thin slices. Skin and slice the kiwifruit. Dunk the kiwi into a mixture of 1 tablespoon water and 1 tablespoon lemon juice to keep them green during the drying process.
Heat the oven to 275 degrees F. Place cheesecloth over metal drying racks and place on a large jelly-roll pan or directly on your oven grates, depending on how wide they are. Place the fruit on the cheesecloth and bake for 1 hour. Rotate the pans and flip over the fruit. Bake for another hour; rotate and flip again.
Bake for another hour. It’s now been 3 hours of low and slow drying. Check your fruit. If it’s still soft, bake for another 30 to 60 minutes with the oven door cracked open. I used a large wooden spoon to prop mine open. If it’s dry to your satisfaction, turn off the oven but leave the fruit in there until it completely cools.

Freeze Drying vs Spray Drying – Which is Most Suitable For Your Projects? The demand for productivity and profitability in the freeze drying, also known as, sector is increasing. This increase is driving practitioners in the industry to consider the benefits of freeze drying compared to,
- Which Should You Choose? Freeze drying is widely recognised in the biopharmaceutical industry as the preferred method for preserving a wide range of pharmaceutical formulations and biologicals.
- This drying method is particularly beneficial when stability in the liquid state is inadequate, storage requirements are too stringent, or a solid form of the product is desired to improve shelf life or enable shipping between differing climates and environments.
is certainly the established ‘go to’ drying process across a variety of materials and applications. However, owing to the costs, availability of APIs and sometimes processing and production volumes, evaluation of alternative methods is conducted to ensure that the most suitable drying method for the product and/or project is used. Spray drying also offers a variety of benefits. Despite being a comparative newcomer in the industry versus freeze drying, it showcases capabilities to work with higher throughput amounts at a scalable level (continuously rather than batch by batch). As a result, spray drying can also be seen as a viable option for product drying, subject to the contextual processing requirement and product application. Use in the Industry Both processes can be used for a vast range of applications. For example, freeze drying is typically sought out for the preservation of different cell types, fine chemicals, laboratory reagents and injectable vaccines, as well as for the food industry & dairy products.
Because it is typically performed with product directly filled in vials or other containers, this processing method is best suited for formulations that do not require further processing after drying; additionally, vials can be sealed in-situ of the freeze dryer, thus avoiding potential contamination when the cycle is complete.
, on the other hand, is more commonly associated with bulk processing rather than vial based processing. However, it is a common misconception that spray drying is only a suitable process for food and robust bulk pharmaceuticals, where contemporary research suggests it may be a valid methodology for use with some complex products i.e.
- Microencapsulated bacteria and nano particulates, for example.
- Both methods of product drying process can be effective when used correctly, and for the appropriate products.
- In order to achieve optimal results in product processing that includes a drying stage, ultimately the deciding factor for which method will be best for a project, or ongoing processing need, will be the quality of the end product and how it will reach the end users.

How do you freeze dry without a freezer?
Using Dry Ice to Freeze-Dry Food at Home – To begin your freeze-drying process, place the food in the cooler. We recommend using a container at least double the size of the food you are freezing. That way, you can freeze-dry large amounts of food at one time using ample dry ice.
Also place the food in a plastic bag so it’s not in direct contact with the dry ice, but leave the bag unsealed so that moisture can escape. Next, completely cover the food with dry ice. For best results, we recommend using a 1:1 ratio—one pound of dry ice for every pound of food you want to freeze-dry.
At this point, we want to remind you not to seal your cooler or container completely. In sealed containers, dry ice can create high enough pressures to rupture or explode. For that reason, if you have to use a lid or an improvised container like a plastic tote, make sure to drill holes.
- To avoid drilling holes in your cooler, we recommend leaving the lid propped open.
- Lastly, let the process take its course and wait until there is no more dry ice in the container.
- At this point, the container is now full of carbon dioxide and free from any moisture.
- Wait to remove the food until you are ready to place it in bags immediately.
We suggest using high-quality freezer bags to store your food. As you transfer your freshly freeze-dried food into bags, take your time and pay attention, making sure no moisture enters the bag—that will ruin all your hard work! For best results, we recommend using a vacuum sealer.

How do you make freeze dried fruit? Crispy Green Process – The process of freeze drying fruit takes place in three steps which, appropriately enough, begins with freezing the fruit. How is Fruit Freeze Dried: Step 1 Our process starts start with selecting top-quality fresh fruit, sourced from certified, carefully selected growers who undergo a stringent audit review process.The fruit that passes our review process is then frozen to below zero degrees Fahrenheit.
How is Fruit Freeze Dried: Step 2 During the next step in the freeze drying process, the fruit is placed in a vacuum chamber under low heat. While in the vacuum chamber, a process called “sublimation” occurs when frozen water crystals evaporate directly from ice to water vapor. The fruit then undergoes one more session of drying under slightly higher temperatures to remove any remaining water molecules.
How is Fruit Freeze Dried: Step 3 During the third and final step, the freeze dried fruit slices are collected and inspected. Qualified fruit slices are packaged into moisture-proof and air-proof packages to preserve nutrition, flavor, and freshness. Crispy Green products are packaged in high quality triple-layer poly-bags with an aluminium lining to protect the finished products from moisture and light for a long shelf-life.
- All of our fruit is processed and freeze dried according to the Hazard Analysis and Critical Control Point (HACCP) system, an international standard that identifies critical control points, sets safety procedures and preventive measures, and maintains strict documentation for certification.

Is there a difference between freeze-dried and freeze-dried raw?
Is Freeze-Dried Dog Food as Good as Raw Dog Food? – The question of whether freeze-dried dog food is as good as raw dog food is based upon your own preference when it comes to preparation and cost. Freeze-dried dog food is a part of a line of raw, meat-based foods that have ingredients from food animals that are not cooked.2 The only difference between freeze-dried dog food and raw dog food is that freeze-dried dog food has undergone a process to remove most of the moisture in the product.3 Nevertheless, in the freeze-drying process, nutrients are maintained.1 In addition, the appearance of the product is maintained and some bacteria may be killed.3 In terms of cost, the extra step of processing the food product through freeze-drying may make it more expensive than raw dog food diets.3
Is a freeze dryer just a dehydrator?
The Freeze Drying Process – Freeze dryers are a little more complicated as it features three steps to remove as much moisture inside. Unlike dehydrators, freeze dryers take your material to a process called Lyophilization. In Lyophilization, your material is taken to -30 degrees Fahrenheit to freeze the water content, usually taking around nine hours, depending on the Freeze Dryer.
