Is it safe to freeze dry raw meat? Yes, you can safely freeze dry raw meat. However, it's important to handle raw meats properly to prevent contamination.
Choosing between an oil-free pump and a premier oil pump for our Harvest Right freeze dryer was a tough decision at the time. But with the benefit of hindsight and having operated both, we would absolutely choose the premier oil pump if we had a do-over.

Here are the key features and components of a triple pass rotary drum dryer: 1. Triple Pass Design: - The material being dried passes through three rotating drums or cylinders, hence the term "triple pass." Each drum serves a specific purpose in the drying process. 2. Material Flow: - The material enters the dryer and first passes through the innermost drum. After the initial drying phase, it moves to the middle drum and then to the outer drum, undergoing additional drying in each pass. 3. Heat Source: - Heat is typically provided by a combustion system, such as a burner or furnace, located at one end of the drum dryer. The hot gases generated by the combustion process flow through the rotating drums, transferring heat to the material. 4. Air Flow: - The dryer is designed to optimize air flow through the drums, ensuring efficient drying. In a triple pass design, the material and hot gases move counter-currently through the three drums, enhancing heat transfer and drying efficiency. 5. Lifting Flights or Lifters: - Lifters are internal components inside the drums designed to lift and cascade the material as it rotates. This movement promotes good heat transfer and uniform drying.
As you can see, the capacity more or less doubles with each model but the cost does not. The larger models use more energy to process the larger batches of food as well, so don’t neglect energy costs when you compare these as that impacts efficiency as we discussed earlier.
Freeze dried food is lighter than dehydrated or canned food – Dehydrated food retains about 20% of its water. As opposed to freeze dried food that is about 2% water. Canned food retains all of its moisture, and you also have the weight of the can to content with.
I freeze dried both cooked and raw pork chops; the cooked pork chops tasted great cold without reconstituting them, the raw pork chops reconstituted beautifully and fried up great. I could not tell them from fresh pork chops. Now I can put away exactly the foods I want.
But, freeze dryers can handle a wide range of food and retain nutritional value (and flavor!) much better than dehydrators. They also give the food a massively long shelf life, extending some perishable foods to over 25 years!
All of our picks use similar pumps and all get down to -40 degrees to effectively freeze dry the food within a reasonable amount of time. Industrial freeze dryers can do this more quickly but are of higher capacity and are much larger.
Investing in a Harvest Right freeze dryer isn’t just about the upfront cost. Currently a medium model with the premier oil pump will set you back about $3,200.
It’ll draw an average of 1080 W/hr while running, even with the much smaller batch sizes. Still, if you plan on using your freeze drying appliance occasionally or as a hobby, then this model will more than fit the bill.
