I am looking for a more defined "heuristic" curve based upon the internal temperature. I am sure that your engineers probably have tables for such things. I also know that different foods freeze at different rates, that is why I am asking for a heuristic answer.
5 Posted September 16, 2015 (edited) Gypsyman: Proof again that "great minds think alike". In my initial pondering, I thought using an oil filter base would be a logical approach -- but I didn't have one handy and figured my car might miss it. Besides, one of my goals was to keep this affordable, and they tend to be a little pricey.
My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.
Adele Faubert Albert was very helpful in answering questions prior to place the order and then with following up on delivery. The unit arrived on the date scheduled even though the tracking notice was not updated once the unit arrived in Canada. The pre-arrival instructions were very helpful as we were prepared once the unit arrived.
The good news is, their collection of home freeze dryers for sale are high-quality and possess so far delivered great results across a wide spectrum of buyers.
Upon turning off the pump (no isolation valve on the pump - standard setup), the chamber pressure rose quite rapidly going to 2000 mTorr and Know More continuing up in a couple of minutes or so.
They can last for decades, with regular maintenance of course. It’s like any other major appliance, it has running parts and will need to be maintained or repaired as needed.
The initial cost can be high, they require adequate space and power supply; also, they can be noisy during operation.
We sold a grainmill also, hyped by a friend who had several. Used it some also. Nothing happened and other things incl food was donated or tossed. Now retired, who has time or money to throw away again? not me.
Furthermore, the modern freeze dryer systems have vacuum pumps and refrigerators which enhances the drying cycles and saves energy.
The right drier for the job, regardless if it is for mass industrial use or small batch pharmaceutical ones, can dramatically increase productivity, minimize waste, and save money in the long run. In this article, the process and techniques of freeze drying, the necessary features when picking a freeze dryer, the use of it in pharmaceuticals and food, and the future of the industry are discussed.
Recently we took a trip to Hawaii. After doing some research, I found a few restaurants that I was fairly confident would be safe for my son. However, I also knew how expensive even regular groceries are in Hawaii, let alone gluten-free food.
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
Making food in your own freeze dryer is less expensive than purchasing it commercially. You can purchase food in bulk and freeze dry it for later. With the current high food prices (which could easily continue to skyrocket), it’s nice to buy in bulk or on clearance to save money.
