Have you ever tossed out spoiled produce or leftovers? How about those cans of food that are nearing their expiration date sitting on the shelf at the back of your food storage?
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.
You can freeze dry things with fat and oils in it. The point isn’t to completely get rid of all the fat, but to reduce it. The reason being is for the storage process.
With the combination of pharmaceutical and food products needing to be more shelf-stable than before, acquiring ideal freeze-drying machinery is crucial. Modern freeze driers have much more sophisticated control of temperature, pressure, and moisture which guarantees the quality of the product as well as meeting regulatory standards.
” As sponsored posts go, it was very accurate and not nearly as “salesy” as I’ve seen from other sponsored posts. I’ll share it below, but first I want to answer the question directly.
22F, achieved by dividing nove hours by 110F (the difference in food temps). We both know that the FDer doesn't do linear as the temps fall faster early on and slowly peak to max low temps, but the food freeze time might be a tad more linear than the FDer as food is denser and must be frozen throughout.
Automation and control features are equally important in dry freezing machinery. Remote monitoring, remote data access, and real time data tracking automation improves process consistency by reducing manual input.
The one "gotcha" I encountered in making this is that a typical car oil filter attaches with a 3/4x16tpi threaded pipe. I could find pelo such pipe anywhere. My solution was to use instead a 3/4x16tpi bolt, and then drill a hole through it.
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.
Out of caution, I have only ever taken website 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.
As a bonus, freeze-dried products are lightweight making them desirable for outdoor activities, emergency kits, and even space missions. Food manufacturers looking to broaden their offerings find freeze-drying prepackaged food as an enticing option because of the increased safety of food and reduced waste.
The only way I know to filter the water vapor out would be a cold trap. They website usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Harvest Right’s lyophilizer/freeze dryer is the perfect addition to any laboratory. The scientific freeze dryer can be completely customized with your preferred processes.
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.
