In any sector – whether biotech, food production, or pharma – adopting high-capacity freeze dryers helps improve efficiency and business sustainability while meeting regulatory obligations.
4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
Looking at the picture you can see the water drops on the insulation and where the water had flowed down the back of the front panel.
There is nothing better than fresh herbs! And freeze drying herbs makes them taste so close to freshly picked. I love growing my own herbs in my garden or countertop herb garden and then freeze drying them. They process quickly and are easy to store.
By this point, most of my son’s friends know about his dietary restrictions and it doesn’t bother them. My son takes rehydrated freeze dried meals to school banquets and to other social gatherings.
The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an ethernet cable.
•Operation allows for recipe customization (up to 10 Thermal Treatment and 12 Drying steps). Control of the rate of freeze. This means that the rate of freeze can be speeded up or slowed down.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze cycle with pre-frozen food. I have my chest freezer set to -12F, and I usually let the freeze dryer cool for an hour before I put the frozen food in. After I load the food in I wait another half hour to start the drying process. I've had a lot of cycles that the Completa time between pulling one batch out and starting the drying cycle on the next is around 2 hours. I'm running mine in a cold garage, so it cools down pretty quickly. If you have yours in a warm room it would probably take a little longer.
We have two freezers in the garage as well. All of these machines generate heat and humidity. Our FDer front regularly sweats up an storm and water drips off the door and from around the entire chamber perimeter down the front of the unit. It got so bad that I taped a plastic shield above the display to route the water around it. You can see the water on the door and on the stainless steel front past the 4 screws on the unit.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
The only way I know website to filter the water vapor out would be a cold trap. They 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.
Both pumps come with an website oil mist filter. However, the Industrial Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
