I would prefer those fittings to have internal Este rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the Este ring and you're back in business.
After the 3rd cycle I had hit my 20 cycle oil limit so it was time to change the oil. This time I took the time to add a flush port to my pump. When I replaced the plumbing with larger diameter brass and a cutoff valve I did not think to add the oil flush out port.
Evaluating efficiency and operational success is essential in selecting the right freeze dryer. One of the most important factors is capacity. For small batch production, pharmaceutical companies need precise and accurate freeze dryers, while food producers require large scale systems for mass production. Aligning a freeze dryer with the production requirements increases efficiency.
One of the reasons I like the small freeze dryer is the size. At the same time, my large freeze dryer takes up space equivalent to a clothes dryer—the small one doesn't.
•Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
For the price of a large home freeze dryer one can have 48 servings of premium freeze dried beef delivered to their home every month for a year with promo code “jdr“.
I think a community-built troubleshooting manual is a great idea. These machines are simple in some ways, and more complex in others, and having a lot of eyes on the problem is always good.
Once we got into the groove of freeze-drying food, we have been extremely pleased with the purchase. But know this going in if you’re thinking this is an “easy button.” It’s not. In fact, in many ways it has changed our lifestyle. For example, we now often cook for a family of 8 even though it’s just us and the two kids.
Use a professional shipping service that specializes in handling industrial machinery. Ensure the dryer is properly secured and protected to prevent any damage during transit.
We have two freezers in the garage as well. All of these website machines generate heat and humidity. Our FDer front regularly sweats up an storm and water drips off the door and from around the entire chamber perimeter down the front of the unit. It got so bad that I taped a plastic shield above the display to route the water around it. You can see the water on the door and on the stainless steel front past the 4 screws on the unit.
Remove all ice every 8 hours of drying time. It is amazing how much faster the drying time drops doing this. A side benefit is water vapor does not contaminate the oil as fast. I've gotten up to 20 cycle per oil change by more info carefully monitoring the oil and water.
How are freeze dryers shipped? Delivery is via FedEx Freight for most urban addresses, while rural locations may use a last-mile delivery service. All deliveries include curbside service and require a physical address to schedule delivery appointments.
If you don’t have the time or money, or if you believe the food crisis will hit hard very soon, then it makes more sense to buy freeze-dried food instead.
Unfortunately, freeze-dried food can often be very expensive. We’ve seen this first hand as the only company that sells both frozen beef boxes to store in the freezer for up to a year as well as freeze-dried beef cubes to store in the closet for over a decade.
