- Anything with too high a fat content may give some problems because the oils or fat will not evaporate, only the water will.
Congratulations! You are now the owner of a new freeze-dryer; or you are ready to make the purchase! While the freeze dryer itself is a major investment in food preservation equipment, you will want to make certain you are prepared with a few other items
I would prefer those fittings to have internal O 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 Este ring and you're back in business.
Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency
The bottom line regarding freeze-dried food is that hoe freeze dryers are an investment! An investment that pays you back and makes you more resilient in the process.
oito) The vacuum port was up next. You can see the condensation on the brass fitting. That means cold is escaping and heat is getting into the chamber. This small section was placed inside the panel.
Gas appliances are much more powerful, and better suited for large scale commercial operations. The gas appliances heat up faster and are typically more durable. For preparing meals, gas ranges are the better choice for chefs.
You can determine when the product is dry by feel or by calculation of the amount of water remaining in the product.
This product does not come standard with a new freeze dryer order. Current customers with an older model freeze dryer will need an adapter for the oil free vacuum pump. Harvest Right will provide the adapter free website of charge.
If this sounds too familiar, it’s likely that you’re wasting a great deal of money on eating out in your refusal to attend to your broken fridge.
Used freeze dryers can also be worth your while, but it’s imperative to check them before buying and be sure they’re working well. Lastly, always avoid websites that sell off-brand equipment and sketchy manufacturers.
I love that the small freeze dryer can be placed on a kitchen counter. Having it in the kitchen makes it convenient and always ready to start the freeze-drying process.
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.
