@FreezeDriedIceCreamPrepper

Жыл бұрын

@lillypatience You definitely don't need to pre-freeze for 8 hours. Just like most things you freeze dry, the colder the better to start with. But since ice cream is generally already in the 0° to 10° range anyways, extra deep freeze doesn't take off that much time from the process. What you DO want to do it have your freeze dryer as cold as possible when you put the trays in. So this is my general order of operations: 1) Ideally have your trays in deep freeze beforehand, so you're not putting your ice cream on warm trays 2) Start the cycle and start lowering the temperature in the chamber 3) Start scooping your ice cream onto frozen trays and put them in when the chamber gets down to at least 10° *Ideally this should be in the coolest room you can stand. Since it's winter, I do it out in our garage where it's around 40° and the ice cream doesn't really have time to melt in the time it takes me to get it on the trays

It's really a VERY simple process. The components: A vacuum chamber - just an airtight metal chamber. A vacuum pump to lower the pressure in the chamber. A freezer unit to freeze the chamber to -40º. Heated shelves in the chamber to gently heat the food and "boil" off the water WHILE still frozen. In the same way that water boils at a lower temperature at high mountain elevations, in the freeze dryer vacuum chamber the pressure is so low that the ice will go from a solid to a gas at temperatures too low for the ice to melt; a process called sublimation - from a solid directly to a gas. (Like when dry ice disappears) The water from the food ends up on the wall of the chamber as ice in a process called desublimation or deposition - from a gas directly back to a solid. The chamber walls are being used as a moisture or vapor trap, so the water doesn't go into the vacuum pump.

Hi Dan, Well, I finally have the imported FD working now and going to attempt some sweets ( candy) . My machine is very different to a harvest right in the way it works, i need to program every stage manually with temp and time. As a best guess would you gradually increase temp in smaller increments like 10C or larger jumps say at 30C , Also would you finish at 50C or 55C so as not to cook it. It may be a bit tricky to work out but I am going to run with a 30 hour cycle starting at -45 and move up to 50c in 12 increments. Well that's the plan anyway. Thanks again for the wealth of information and this channel.

@SchoolReports

Жыл бұрын

In general, I would probably start with smaller increments like 10ºc with a max of 50ºc at first. With sweets :) the total run times can be very short (just a few hours after the chamber is completely cold), and you can even bypass some of the lower heating steps and go right to the higher temps. This is because there is almost no water in them. Some candies do almost nothing even at 65ºc, and some will get so big they will stick to the next shelf up if heated above 50ºc. The newer HR freeze dryers have the ability to go to 65ºc (150ºf) when doing candy. I didn't like the results of most of the candy when done at that temperature; it over puffed. I have done almost every batch at 120ºf (49ºc), with a few at lower temps to experiment. The Harvest right firmware cycles the temp on and off many times to try to keep the pressure within a range. In a lot of ways it's not as sophisticated as yours; but usable by a wider user base. Maybe this will help - How To Graph Your Harvest Right Data kzread.info/dash/bejne/lnp8rbymkqevd5s.html

However, maybe when the vacuum first starts and the air is being pulled out or when when the drain valve is opened, the rushing air MIGHT move some powder, so we cover it just in case. We've never seen evidence that any powder has moved, but we do cover it. I see no issues with just pouring the various powders you listed directly on to the trays, as is, I would NOT add water. I should do a batch of flour to see how much water it has. Minute Rice sure had a lot.

As you are aware, I don’t watch these in any particular order. In fact, they pop up in my daily feed randomly, so I’m not aware if and or when you’ve recorded another candy batch. Did you ever try the Mike & Ike’s again? I have them and plan to experiment with them; no one I’ve observed has gotten a result with just putting them on a tray at higher temperatures, you experienced exactly what I expected. Are the clear portions of those bags you used a thinner Mylar (like 1 mil), or merely cellophane? I laughed when you mentioned that you wanted to remove the candy to prevent any rehydration from the surrounding air.. I’ve found Skittles I freeze dried a week or more ago on the table and they’re just as dry and crunchy as when I pulled them out of the freeze dryer! Speaking of which others have laid a parchment on top of the skittles and loaded a second layer to excellent results. I get one 56 ounce jar to cover all 4 of my Small trays, I haven’t tried a 2nd layer on my thinner trays. Yours are deeper and there’s greater clearance on your older model. You are correct regarding not needing to freeze the chamber before entering the dry cycle with candy. After the initial cool down, I will skip the warming of the trays and go straight into Final Dry at 145-150 degrees for 3-4 hours. You probably don’t want to try this with your gummy bears if you really want them to appear as “non-gummy” bears when done. There is so little moisture that the heat vaporizes it during the dry cycle and sublimation isn’t needed. Oh that is not to say that certain types of “candy” won’t rehydrate. Marshmallows certainly will. I’ve come across the stray marshmallow days later and while still having a crunch, they are noticeably not as dry. But my “laugh” is in my opinion still warranted for “immediately” trying to keep from rehydrating, most candy will take a long time or in the case of the skittles I don’t think they rehydrate at all. I’ll let you know what occurs with my Mike & Ike experiments on some other video. While I did receive the cheese slicer, I haven’t bought any ice cream yet to slice.. like you I get caught up doing other things. How many #1 children do you have (you stated your “other #1 child” wants to bring over some candy too)?

@SchoolReports I wondered about the clear side because it looks pretty flexible. I used to buy comic book Mylar bags that were 4mil. They were really rigid. I still have them for my expensive books, but Bill Cole Enterprises had to return the exclusive rights to the patent holder Gerber a number of years ago, and they started making 1mil bags that were as flexible as cellophane but still had a minimal archival quality. I refused to buy them. The aluminum mixing with Mylar for freeze drying bags appears to have made them more flexible than Mylar by itself. I would question whether the clear side is truly 3mil if they’re as flexible as they appear. I haven’t compared the HR 7mil bag’s thickness to the 4mil comic bags. There may be a thickness difference. I don’t dispute freeze dried fruit or other healthy foods ability to rehydrate quickly from the surrounding air, perhaps you misunderstood. I was talking about the candy which is mostly corn syrup and sugar. If you have some articles about rehydration of sugar, corn starch and syrup that’s been cooked at high temperatures to form candy, please supply those.

@@MisterEMystery 🤣 If you knew me you'd know that I didn't assume that the bag was 3mil because it was sold and labeled as 3mil, I measured it myself. They are 3mil bags. (Typically the metallisation is added by vapor deposition, it's not mixed with the plastic film) The hygroscopic nature of sugar is so well known I'm not going to spend a lot of time on it. Suffice it to say, all freeze dried items are hygroscopic and if I can't bag into the final bags right away, I'll at least bag into some kind of temporary plastic bag. I'd rather be safe than sorry. Pastry science #3 - The properties of sugar www.roadtopastry.com/blog/pastry-science/pastry-science-3-the-properties-of-sugar-part-ii 5. Hygroscopicity All sugars are hygroscopic, albeit at different levels: this means that they have a tendency to “grab” water/humidity and keep it as long as they can. . . . . . . The most hygroscopic sugar is fructose, which can keep baked goods moist longer than other sugars. The same applies to the syrups containing fructose, like agave syrup and honey. The different levels of hygroscopicity also mean that we cannot simply replace 100% of the sugar in a recipe with honey, because the final consistency will be altered, too soft or spongy.

If you ever put a lollipop in the fridge, only to return to a pool of bright pink sugar syrup, it is because of sugar's water-attracting property. But being hygroscopic does more than melt your lollies. . . . In ice cream-making, we call sugar an "anti-freeze," because its hygroscopicity prevents crystal formation and creates a softer, creamier texture. www.slideserve.com/halia/day-5 41. Sweeteners Sugars are hygroscopic. • They attract and bond to water, pulling water from proteins, starches, and gums. • . . . 42. Sweeteners • Sugars and other carbohydrates vary in their hygroscopic nature. • Fructose is highly hygroscopic. • Isomalt is not very hygroscopic. • Hygroscopic nature of sugar and other carbohydrates: • Is sometimes desirable. examples: soft cookies, icings. • Is sometime undesirable. examples: powdered sugar on doughnuts; spun or pulled sugar.

Where did I get the 4 by 4 pans you freeze Thanks

We bought our pans at the Dollar Tree store, I have a picture of the pans on the Community page. They were called 8x8" but the bottoms are about 7x7", a perfect fit for our medium freeze dryer trays. (Turns out they have them online too www.dollartree.com/cooking-concepts-square-cake-pans-75-in/10065 ) The different batches of pans that we have bought (over the past 20 years) have had slightly different side slopes, which would require a slight change in the divider shape. And, the divider we use in the pan is just something I designed and 3D printed to fit our pans. Here is the design and print video if you are interested; kzread.info/dash/bejne/ZX-AxM6Jc7fWeM4.html They were printed with ABS then vapor/acetone smoothed to seal them. The file is on Thingiverse. Another viewer used cut some out of thick plastic (like thick cutting board) to make their dividers. (They did have a laser cutter) I'm planning to try to figure out how to make a good, usable (1/2" thick) divider without using a printer. (For those odd people who don't have a few 3D printers) Clarification on the 2 1/2 pans per tray; it only works IF the divider is the thickness I use. (or thicker) The freeze dryer trays actually fits about 1/2" less than 2 1/2 pans; that's one reason I made the dividers that thick, and to fit the magnets.

🤣 Glove comment people crack me up! I wear gloves all the time they are _needed._ 1) Do you put on gloves every time you make a sandwich or pour a bowl of cereal for yourself? 2) You don't have to worry, I'm not going to share!
