I also love finding clearance deals on produce and other items. My family is no longer surprised when I bring home piles of produce, meat, cheese, or whatever else I find a deal on.
The food and pharmaceutical industries crucially rely on freeze drying for the long-term storage of products. This method enables businesses to preserve product quality, extend shelf life, and improve stability.
(had to replace the whole galvanized T piece with new wires in it) Seems they are epoxied in there, and in my experience passthroughs are a problem spot, so it's not at all surprizing that there was a slight leak there. In any case, I thanks the folks at HR for sending parts and sticking with me throughout.
What type of oil does the vacuum pump use? Harvest Right freeze dryers use food-grade vacuum pump oil, which is available for purchase. One gallon typically lasts several months with proper filtering and maintenance.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
How does freeze drying work? To put it simply, it freezes the food then goes through a sublimation process where it dries the food.
And once you have resolved your issue I hope you will stay around and talk to us all about what you have been get more info drying in your machine, etc. 1
The pros and cons are easy to understand. In fact, there really is only one pro and it’s a huge one. YOU control the food you’re storing away for yourself and your family. Those who are willing to spend the time and money to freeze dry their own food should do so as long as they’re going to be committed.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
Out of caution, I have only ever taken mylar bags in a checked bag and I’ve never had a problem. I know of people who have taken them in carry-on bags as well without issues.
Lean meats work very well. Meats can be freeze dried either raw or cooked. If you are processing beef or pork, be sure to remove as much fat as possible first.
Run full system test with no food in chamber (results, 630 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
