If you freeze dry sliced strawberries, (it saves a lot of energy if you deep freeze them first), you’ll be unlikely to get a mess. They are a great starter item. We found that putting down some parchment paper in the trays, makes things easier again, especially if you’re still setting up your household I don’t necessarily have all the plumbing connected. Parchment paper will lift right off the trays, and you can use a clean dish washing cloth to just dust away any remaining particles of freeze dried strawberries. We found the same thing with freeze-drying, sliced bananas. Except it’s a lot more efficient to slice the bananas lengthwise. Then we dip them in a solution of lemon juice with honey in it. Some of us say there’s no difference in the taste, but more of us think it’s worth the effort. Especially to keep the bananas, nice and brightly-coloured. There’s a big positive correlation between how appetizing something looks and peoples’ willingness to eat it.

This post has been, by far, my favorite post about the cleaning of our freeze-dryers. You teach the man to fish and share the whys so we can make educated choices. I last watched it over a year and a half ago. I'm now back out on the net researching more about the sanitation around our food prep. The ball valve seized on me, so in my last search for answers to resolving this, I found out that USDA only supports stainless steel for food-grade metals, not brass. But the parts on the tubes connecting to both ends of that ball valve are brass, not stainless. So that brass is rusting. I clean my machine EVERY use. So I was shocked to see what I found when I took the ball valve off. All that rust and gunk building up around that ball valve was nasty and has me concerned about how healthy it is when it's opened and all that gunk is pulled back into the chamber? Have you checked that, too? I realize this video is almost a year old, but I wanted to know if you have experienced this. I'm off to check your more recent videos to see if you have covered this. I still wanted to share my concerns here.
@Philat4800feet Жыл бұрын
A stainless steel ball valve would be ideal. Another issue to consider from the FDA is the term "Incidental". How likely will food come into contact with other substances. This is the key word when dealing with food grade vacuum pump oils and other materials. You are correct about introducing substances back into the chamber from the drain system. Many have contaminated their food when the drain tube becomes submerged in water. Cleaning the drain system is often over-looked Good thoughts.

Question: Since cleaning with acid poses a danger to various parts of the freeze dryer (like the chromium oxide layer on the stainless steel or the ball valves), is there also a concern when freeze drying acidic foods? Like citrus, tomato, or foods with a lot of vinegar? I ran my first bread batch with the bread soaked in vinegar, but this video is making me wonder if that is something I should avoid. I also really liked doing freeze dried oranges, but would doing citrus reduce the life of the freeze dryer?

The problem with soapy water is making sure it's rinsed out. That section of tubing is under vacuum.

A 70/30 alcohol/water solution may work better, followed with rinsing.

Thanks for a great report on cleaning the Harvest Right freeze dryer! Isopropyl alcohol it is. Q: I freeze dried white bean chili. I have cleaned the freeze dryer completely after this batch, but there is still a faint smell of the "chili spices.' Can I set a bowl of baking soda inside the freeze dryer with the door closed so that the baking soda will absorb the smell? Will the baking soda migrate out of the bowl and attach to the surface of the freeze dryer if the system is not turned on? Would I have to wipe down the surface again after letting baking soda sit in a bowl inside the freeze dryer? Thanks for any insight.
@Philat4800feet Жыл бұрын
The soda could become airborne and enter your pump. I would pass on the soda. You're smelling mircoparticulates of your chili, and those particles could be in your drain line, inside the back of the shelves, inside the corrugated plastic insulation, etc. A fan place in front of the door can help defrost and remove smells.

Vodka is so much more expensive than IPA, I wouldn't bother with it. The main reason people want to use vodka is because of the government adding poison to non-taxed alcohol products. However I do not believe the government adds that to IPA because IPA is naturally toxic since our body cannot metabolize it. IPA can form in our bodies during diabetic ketoacidosis, so it isn't inherently deadly, and also the IPA is easily removed because of its high vapor pressure by just airing out the freeze drier after using IPA.

If you're not freeze-drying leave your ball valve open. To clean the tube, pour a 1/2 cup of hot water with a 1/4 teaspoon bleach down the inside drain with your valve closed (do not mix the bleach with any other cleaner). Wait 60 second and release the valve, pour any remaining sanitizer down the drain. Follow this up with two cups warm water to rinse.

@Phil at 4800 Feet: Thanks for your video. I especially appreciate the comment about the ball valve, as just two days ago the factory recommended to me that I use 10% acetic acid vinegar to flush out the drain and hose. (!!!!) Your tip about the rubbing alcohol is also a really super good one to have. I imagine that these two tips alone will change the way many, many people clean their machines. That is no small service that you offered with those two comments alone. Your microbiology techniques are a little unconventional here; I’ve never seen petri dishes inoculated in quite that matter, but you did a great job of making your point. Spores are in the air everywhere, and not just on surfaces. Sometimes we use that information to our advantage, such as people do when they want to make sourdough, or vinegar or kombucha’s or even wines without adding their own yeasts. Other times, it amounts to contamination, which is exactly your point. And of course yeast and bacteria are not the only things in the air. There’s a possibility that some of the contamination that you were able to culture, came from airborne contamination. There’s probably nobody that couldn’t benefit from knowing this information, and how to use it to the best advantage possible. Anytime we leave possible residues of food on surfaces, including the interior of the chamber, we run the risk providing a nutritious substrate for microbes to colonize our tools that are used to produce and protect our food. The metallurgy report that you provide is really useful; there’s probably a lot of people with no idea about the fragility of that coating that keeps the stainless steel chamber in prime shape. Thank you very much for that. It’s probably not a bad idea to keep an extra ball valve on hand, since this sort of thing that person might not intuitively consider when it seems that compression is suddenly lacking. If water alone can do this, since water must of necessity pass through the draining mechanism after most uses of a sublimation set up, eventually it’s probably going to happen to everyone. Your presentation is well worth a second listen, and as soon as I send this comment, that’s what I’m going to do. The information that I’m actually looking for today, has to do with cleaning. There are certain items that you can put in your freezer dryer, that no part of the information that comes with the machine, indicates can really expand upon the freezing sublimation process. Eggs are one of those. Lol. If the machine noises up, if they almost invariably do, the sensors can get confused. The machine can spend days trying to sublimate the ice formation, as with all nondry food. Nutrient matter can be drawn in the intake port in the Upper 1/3 of the machine, and my concern would be that that material kind of drawn into the pump and cause problems. I’d really like to hear if you’ve got some ideas about cleaning out that port that leads from the inside of the compression chamber out. Thanks again. Your thoughts on this matter would be very appreciated. Edited to fix some auto correct errors. Please note. I did not actually put a frog in the machine. That was pure auto correct. For anyone who saw that and thinks that I put a frog please note that it was only eggs. Update: I’ve actually downloaded The patent application with the schematics, before managing to get a hold of the factory. Actually, making contact with somebody who was not in a Third World country, and I never seen such a machine, was no small task. they need to do better in that department So a person can just pass a pass-through or a brush through that opening to the outside to clean it. In my case the hose did have to come off the machine and the pump, and it had to be cleaned out. It doesn’t hurt at all to use water on the hose, But No solvents, other than water, if memory serves. (It’s been a year since having to do this.) Again, in my case, the egg hadn’t actually gotten pulled into the pump. Thank God. That would’ve been a whole different level of cleanup. I save the vinegar for silicone hoses now, so as not to pit ball valve; And the 99% rubbing alcohol is what I use to clean the machine out now. It also should serve to preserve the coating inside the machine. So eggs go into the machine deep frozen now, as does anything else with a high sugar content. Lol and the moments the warranty is up, your vacuum filter is going on the machine. tyvk!!!!

For me, I don't dilute the alcohol. If you're sensitive to the smell or near equipment that produces a spark, I would dilute to 70% alcohol :30% water. As far as cleaning, if I'm doing cooked foods, I'll clean after five loads. If raw eggs and meats, after the load.

How about Five Star PBW or Starsan used in the brewing industry? You can get them from any brewing supply store. Would like to hear your thoughts.
@Philat4800feet3 жыл бұрын
I had to look PBW and Starsan up. The PH level for PBW is 12. For Starsan (Star San) is 3.5. 12 is really high on the PH scale (alkaline side), while 3.5 is about the same but on the acidic side. The better cleaners should be around 6-8.
@lorencolt3 жыл бұрын
So the brewing industry has been cleaning their stainless vessels with the wrong stuff. They clean after every batch with PBW and for good measure they spray everything with starsan just before starting a new batch. I have not heard of any problems with it breaking down stainless after decades of use. They pump it through their hoses, pipes and valves that are not easy to disassemble and clean.
@Philat4800feet3 жыл бұрын
I can't speak for the brewing industry, but... There are two issues: 1. ASTM wrote the standard A380 for cleaning stainless steel and retaining the protective chromium oxide finish and only a PH neutral cleaner should be used. 2. According to the FDA, and most health departments, only approved cleaners should be used around food. Cleaners not approved must be rinsed, and then sanitized with an approved sanitizer. For home and personal use you can clean your FD with anything. If you start selling food to the public that changes everything. I doubt any of us will ever clean the chamber of the FD enough to ever see it fail. Perhaps I'm being too anal retentive. I just believe in doing something right the first time.

JeffD: I had this very problem just a couple of days ago. The factory advised me to pour vinegar containing 10% acidic acid down there. Now we know that’s not so good for the finish on the stainless steel, so what I did is I put a funnel in the drain, and filled the funnel. You did a great job of clearing debris out of the drain. Factory also said that hydrogen peroxide was OK to use. Henceforth though I think I’ll be using rubbing alcohol. I do like the funnel for the reason that it fits in the drain and keeps vinegar from contacting the finish in the sublimation chamber.
