I honestly think putting a thermometer inside the unit is an excellent idea. I sent the following note off to Harvest Right Support in an effort to gain a little better understanding of the process.
Furthermore, the development of vacuum drying and the control of temperature rise have increased the efficiency of the freeze-drying systems which leads to reduced cycle times and lower costs. The development of the industry gives a lot of hope for the future of freeze drying in both the pharmaceutical and food industry.
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.
Powdered bananas can be used in banana breads. We like using powdered fruits to flavor cakes or frostings.
When my son goes to college in a few months, we will send him with many freeze dried meals and continue to mail them to him as needed. Most colleges don’t have safe gluten-free options, and while in an ideal world my son would be able to cook all his own food, I know that’s not practical or likely. Freeze dried meals on hand are an easy way to keep from being cross contaminated at the cafeteria!
For the price of a large home freeze dryer one can have 48 servings of premium freeze dried beef delivered to their home every month for a year with promo code “jdr“.
Door seal appears good against the plexiglass side, even stripe of contact, nice and wide. Inside gasket groove has been checked for debris and cracks. Looks OK, but the design seems odd to me!
The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an Know More ethernet cable.
A bit of background on me - I used to work in a sold state fabrication lab Buy Now (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start
“Astronaut” ice cream is a fun treat to make and is so easy. Just scoop ice cream onto the trays and freeze before processing.
A description of the product, including details such as build quality, materials used and reasons to purchase.
This is why so many people are buying their own freeze dryers to use at home. The market is essentially cornered by Harvest Right, which isn’t a bad thing since their quality and customer service are both superb.
Freeze drying has been proven essential throughout many industries where stability of the product is of utmost importance. The pharmaceutical field greatly benefits from freeze drying as medicines are rendered impotent for long durations without losing their potency, while in the food industry, freeze drying prevents decay of food without compromising on taste or texture.
Of course, if someone used a larger can, say a #10, that is bigger than the top of the container that surrounds the filter and captures the oil, then the "disk" wouldn't be needed at all. In that case, an AN8 fitting might work -- or maybe there are longer ones out there somewhere.
