And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?
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 O ring and you're back in business.
That means that if you find any authorized online retailer that has a lower price than us, just let us know and we'll match their price!
Hrmm... maybe not freeze drying sorbet but I imagine using freeze dried fruits IN sorbet would give a much more intense flavour. Especially for things like watermelon which I've had great trouble sorbeting successfully.
However, be very careful when buying any machine that was already used. Make sure to test it and see if it works properly before actually buying it.
I'll be looking forward to hearing about the weird and wonderful items you produce. Should be an interesting learning curve.
This method of food preservation causes little damage to the nutritional value of the food being preserved compared to other methods that use higher temperatures, such as canning or dehydration.
Let's do a simple math exercise. Non Frozen food put in freeze dryer at an ambient temp website of 70F needs to be at -40F before the dry cycle begins. things go linear, each hour the temps would drop the food by 12.
Lastly, don’t forget about finding a used freeze dryer on craigstlist.org or other similar classified-based websites. There are plenty of used and well-kept freeze dryers out there that you can get for half the price.
Now that I've filled you in on why the most affordable freeze dryer is the small Harvest Right, let's talk about how you can score one without breaking the bank.
Ask yourself useful issues. Could you very easily approach entire meals in a single cycle? Or is it very best to system different types of foods individually? Does one know how to load the food trays?
Tony, if you see this, I went ahead and purchased the catch can. Do you think it's okay to just purchase a reducer to go from the size of the exhaust to the size of the hose that came with the can?
I've run the system in countless tests including over filling the pump and running the pump without a load (both result in lots of oil spitting out the exhaust port of the pump). I've drained the catch can twice, once with over 5 oz of oil in it, but have not collected any oil downstream in the jar so the system is performing well.
