Welcome back to Freeze Drying Mama! It’s been a while since my last post, and I’m excited to share what I’ve been up to. Life threw me a curveball, and my beloved freeze dryer decided to act up. Here’s the lowdown on the challenges I faced and how I got my machine back in top shape.

The Vacuum Error Nightmare

After moving houses and letting my freeze dryer sit unused for five months, I faced the dreaded vacuum error. Moving 1800 miles and constant bouncing around took a toll on my freeze dryer’s components. I tried restarting it when my warranty expired, but I hit roadblocks with vacuum errors that wouldn’t go away. Understanding the intricacies of these machines is crucial for anyone diving into the world of freeze drying. They’re elegantly crafted but require a lot of TLC to keep running smoothly.

Diagnosing the Problem

My son and I got hands-on by removing the exterior parts to inspect everything closely. I replaced the vacuum sensor and changed the gasket, but the problems persisted. I even went through a thorough check of hoses, epoxy, and sensors, using Windex to spot any leaks. Despite all efforts, the vacuum error persisted, fluctuating wildly.

Gasket and Hoses

I replaced the gasket, thinking it would solve the issue. It did help a bit, but the vacuum error came back. My husband and I taped the door seals for a tighter fit, but still, it didn’t completely fix the problem.

Vacuum Sensor

After countless hours of troubleshooting, it came down to the vacuum sensor. I replaced it and hoped for the best. With the new sensor in place, I ran a test, but the vacuum still fluctuated. This was disheartening, but it indicated that more needed to be done.

The Final Fix: Pump Replacement

The turning point came when I consulted Harvest Right customer service. They suggested my pump was worn out. After running diagnostics and observing the fluctuations, it became evident. My loyal pump couldn’t maintain the vacuum needed for effective freeze drying anymore.

Ordering a New Pump

I ordered a new standard pump and replaced the old one. With fresh oil and a new hose, I set it up and ran a test batch. The vacuum held steady, and the machine transitioned into the drying cycle without a hitch. Suddenly, I felt a wave of relief rush over me.

Successful Test Run

The first successful load of eggs and cheese was a victory. The vacuum held steady at 383 mTor, and the temperature was consistent. It marked the end of a long and frustrating journey of trial and error.

Lessons Learned and Tips

Owning a freeze dryer is a commitment. They are intricate machines that require constant care and attention. If you’re experiencing similar issues, here’s what I’ve learned:

1. Regular Maintenance: Always keep up with routine checks and maintenance.
2. Keep Spare Parts Handy: Having extra gaskets, sensors, and Teflon tape can save you time.
3. Understand Your Machine: Familiarize yourself with every component and how it functions.
4. Use Quality Materials: Invest in good quality oil and replacement parts.

Looking Ahead

Moving forward, I’m excited to get back into the rhythm of freeze drying and updating you with new recipes and tips. I have big plans, from butchering chickens to experimenting with different freeze-dried meals. Stay tuned and let me know what you’re freeze-drying in the comments!
