Secure Your Harvest for Decades with Professional Preservation Tools
The difference between food that spoils in a year and food that stays fresh for decades lies in how you package and process it. Freeze drying supplies are the critical link in the preservation chain, ensuring that once moisture is removed, it never returns until you are ready to rehydrate.
The Essentials of Long-Term Preservation
Achieving a true "forever shelf life" requires battling the three enemies of food storage: oxygen, moisture, and light. Our supply catalog provides the defensive line your freeze-dried goods need to survive long-term storage without degradation.
-
The Oxygen Barrier: Standard plastic bags are permeable. Use heavy-duty
Harvest Right Oxygen Absorbers paired with Mylar to create a completely anaerobic environment that prevents oxidation and spoilage.
-
Surface Protection: Prevent sticky foods from adhering to your trays with reusable
Silicone Mats. These food-grade liners make releasing candies, fruits, and meats effortless while simplifying cleanup.
-
Vacuum Integrity: Your freeze dryer's performance hinges on its vacuum pressure. Regular maintenance using high-viscosity pump oil or upgrading to a
Harvest Right Oil Free Vacuum Pump ensures your cycles remain fast and efficient.
Choosing the Right Accessories for Your Workflow
Different preservation goals require different tools. Whether you are running continuous batches during harvest season or processing delicate botanicals, selecting the right accessories will streamline your operation.
-
For High-Volume Packaging: If you are processing bulk loads, the
12" Impulse Sealer provides a hermetic seal on Mylar bags in seconds, ensuring your oxygen absorbers work effectively.
-
For Batch Efficiency: Pre-freezing your next load while the current one dries is a pro move. Use extra
Freeze Dryer Trays and lids to stack prepared food in your deep freezer, cutting hours off your machine's cycle time.
-
System Maintenance: Don't let a dirty pump stall your production. Keep a
Filter Replacement Kit on hand to keep your oil clean and your vacuum deep.
Streamlining Your Preservation Workflow
Maximizing the output of your freeze dryer isn't just about the machine; it's about optimizing your preparation and packaging processes. Small adjustments in how you handle your supplies can save significant time and money.
-
Optimize Tray Density: Use
Tray Lids to stack trays in your freezer before drying. This "pre-freezing" step reduces the workload on your freeze dryer's compressor and speeds up the overall cycle.
-
Standardize Packaging: Match your Mylar bag size to your meal portions. Storing single-serve meals in smaller bags prevents waste once opened, as freeze-dried food absorbs moisture quickly after the seal is broken.
-
Monitor Oil Clarity: For oil-based pumps, cloudy oil indicates moisture contamination. Change or filter your oil every few batches to protect the pump's internal components and maintain deep vacuum pressure.

Frequently Asked Questions
Why do I need oxygen absorbers for freeze-dried food?
Freeze-dried food is porous and retains very little moisture, but oxygen can still degrade nutrients and flavor over time. Oxygen absorbers remove the air inside sealed Mylar bags, preventing oxidation and ensuring the food stays fresh for up to 25 years.
Can I use standard plastic bags instead of Mylar bags?
No, standard plastic bags are permeable to air and moisture over time. For long-term storage (more than a few months), Mylar bags are essential because they provide a complete barrier against light, moisture, and oxygen.
How often should I change the oil in my vacuum pump?
For standard oil pumps, it is recommended to change or filter the oil every 3-5 batches, or whenever the oil appears cloudy or milky. This cloudiness indicates moisture contamination, which reduces vacuum efficiency and can damage the pump.
Are silicone mats necessary for freeze drying?
While not strictly necessary, silicone mats are highly recommended for sticky foods like candies, fruits with high sugar content, or marinated meats. They prevent food from bonding to the metal trays and make cleaning up significantly easier.
Do I need an impulse sealer for Mylar bags?
Yes, to create an airtight seal on Mylar bags, heat is required. An impulse sealer provides a wide, consistent heat strip that melts the bag layers together, ensuring the oxygen absorber can do its job without new air leaking in.
Can I reuse Mylar bags?
Yes, Mylar bags can often be reused if they were originally sealed with enough extra room. You can cut off the old seal, wash and dry the bag thoroughly, and reseal it with a new oxygen absorber.
