Harvest Right freeze dryers are the best in the industry for home freeze drying, and the best part is that they’re easy to maintain. Let’s talk about the best ways to keep your Harvest Right freeze dryers running smoothly.
Keep Your Freeze Dryer Clean
The best thing you can do to maintain your Harvest Right freeze dryer is to simply clean it after every use. When you allow your system to get dirty over time, it can cause clogs, leaks, or irreversible damage. 2 minutes after each use could save you hundreds of dollars on repairs later on.
It’s especially important to not let water sit in the freeze dryer. You can use chemicals to clean the inside, as long as you dry them thoroughly afterward with paper towels or lint-free rags. If water is left to sit, it can cause rust to the stainless steel trays or damage to the rubber and acrylic components on your next cycle.
Inspect Between Uses
Between every use, simply look around and ensure that gaskets and O-rings still fit into place. Loose items may shift during operation, so it’s best to look around and fix them as you see them. If you notice anything is dirty, clean it right away.
The only other factor to worry about between uses is emptying the water bucket!
Pay Attention to the Oil
If you opt for the oil-free pump, then you can skip this step! For the rest of us, anything that has oil needs an oil change. Oil serves as a lubricant in motors and engines that prevents metal components from grinding each other down over time. Oil gets dirty over time, which causes friction, which will destroy your system if left to persist.
For the best results, filter the oil after every use, which should only take a couple of minutes. If you do this, you will only need to change the oil every 2 to 3 months with moderate use. Without filtering the oil, change every month at the least.
However, if you run your system almost daily, then we’d recommend changing the oil more frequently. Some people change the oil after every 6 uses, but this isn’t entirely necessary. Still, it will keep your system running longer, the more often you do it! Just remember to use vacuum pump oil, not car motor oil.
It’s important to keep track of your oil use. You can leave a note near the system or on your phone and simply add tallies to every completed cycle between oil changes, and make notes of when you filtered the oil. This is a great way to keep track over long periods.
How to Filter
Simply remove the oil from the vacuum pump through the drain plug and run it through your filter. Then, pour the last bit of clean oil into a small, white cup (a Dixie cup will work), and you should see the line between the water and the oil. Try to pour the rest of that oil back into the vacuum pump while keeping the water in your cup.
Water is detrimental to any motor, so filtering your oil can make a big difference! Condensation can quickly cause water buildup in the motor.
Maintain Your Harvest Right Freeze Dryer
Clearly, these are low-maintenance freeze dryers, as they only require minor ongoing work and the occasional oil change to continue running. It really is that simple to care for your own freeze dryer.
