We've had several brief power outtages lately. During the last I discovered my dyer later and found it iced up and the vacuum wasn't operating. Does the outtage affect the pump and cause it to stop automatically because I hadn't done it? I am concerned that the pump may have been harmed by the outtages (not drained water.) Any ideas on that? I defrosted, then turned everything off for awhile. After that I restarted a new batch and so far all seems fine with the pump but I do worry.

Hey Phil! Thanks for the great instructional video here! I'm in the process of diagnosing my issue with the oil-free pump and it appears that it is the vacuum pump itself, not the electric motor, that is at fault. Before disassembling the motor from the pump, I plugged it directly into an extension cord. The shaft turned by a few degrees, would not rotate any further, just made a humming sound and the lights dimmed slightly! I made a video of what I am observing. I submitted a support ticket with HR to see if I could gain any more information to help corroborate what I am seeing. To me, the vacuum pump shaft should have more mobility. But as you see in this short video, it seems the vacuum pump is laboring under some internal resistance, pointing me to a rebuild. kzfaq.info/get/bejne/hs2Ber1p3q2lkXk.html In your experience - does this look ok?? Also, wondering what you think about about the noise that the electric motor is making at the very end of this demo video. Anywho - thanks for your videos! Such a great education. :)

I want to put an accurate mtorr gauge on the machine so that I will know if my vacuum sensor is broken or off. I purchased one but the number system doesn't match. It says Torr(mm) and sits at 40 when the machine gets around 3000 or so and stays there even at 900. I have had vacuum problems for 2 years now. The machine will pull a vacuum if I pull the tray holder out but if it is in (plugged in or not) it will not get below 800 or so. I sprayed out the sensor but it made no difference. I have done most everything now. The machine will pull a vac to 360 if it is empty but if I put the tray holder in whether plugged in or not it will only get to around 800 or so. 1. New pump 2. New door seal 3. New brass ball valve 4. liquid taped all joints 5. turned the door backwards to see if it was warped or had some kind of unseen leak 6. New vacuum hose 7. Hard cemented the fitting where the tray holder wires come out of (at the advice of harvest right when they did not charge for help) 8. Paid the 45.00 just to be told they would call at a certain time and call hours later when I was on the road, then told they would call that evening at 4 and never call or send email. I would like to put a gauge on the machine that will show 500 torr vs 550 torrs. This gauge I have just is not sensitive at all. I have a Yellow Jacket "Torr(mm)/in. hg" 9. I adjusted the door even turning it inside out. 10. There is a minor leak at the door due to manufacturing grinding the weld off the face thus making a low spot of 18 thousands. I made a .125 oring and put inside of the door seal thinking this might take up the space but it did not change anything. I sprayed the door seal area with carb cleaner and the vacuum went from 900 to 895 but that was it. Sprayed out the sensor. Please help.

You have covered your bases. Here's some thoughts: Where the "epoxy plug" is located I don't know why HR would use a hard cement. I had a leak at the wire harness. I found a food grade silicone and applied it under low vacuum so the vacuum would help pull in the sealer. It fixed it. One potential leak would be a cracked weld. That would require NDI work such as a penetrating die inspection. I believe HR has a five year warranty on their chamber. I placed a vacuum micron gauge on top of my vacuum pump. I placed a 304SS tee with the gauge coming out the side and the hose coming out the top. If you have a shop that makes hydraulic hoses, they would have all the JIC fittings. Another thought is using different air fresheners to find your leak. Use them one at a time, in different locations, under vacuum and then smell inside the chamber. Place some towels inside the chamber to capture the scent.

It appears my chamber is leaking through the welds.Most of the bad welds are near the front within 8" or so. This mean I must take the foam off the tank in this area and test again spraying soap water on the outside of the tank on the weld areas.

There really isn't a way to control vacuum amount in candy. Candy contains either No water or very little water. In food the vacuum is controlled by heating the food and releasing water vapor. this decreases the vacuum (sublimation). The vapor is frozen to the chamber wall or is sucked into the pump. Candy just heats up to a liquid or near liquid and the high vacuum boils the liquid and pulls apart the soft parts of the candy (such as skittles).

I would have liked it if you had tested the harvest right one and the navac to see if they are the same as robinair. In any case these results seem to indicate that black gold would be the better choice of the 3 and maybe would be a good alternative to navac which I can't seem to get.

O.k. here is what I have. I have a freeze dryer that will not pull a 500 mtorr vacuum. Here is what I have done. 1. I have sprayed with carb cleaner while under vacuum: A. The door seal near the metal unit and near the lexan/plexiglass door. B. The drain line including all junctions. C. The vacuum side all fittings and sensor and vacuum line both ends. I found no change in vacuum while pump is running. 2. I tested the drain valve by placing the drain line end in a glass of water while under vacuum. No water was noticed in the line after 30 min. 2. I have replaced: A. The drain valve with a solid brass ball valve. B. The door seal. C. The vacuum line. D. The vacuum pump. I placed a dial vacuum gauge on the pump and it read 28.6 in.Hg. I placed the dial vacuum gauge on the drain line end of the machine and it read 28.4 in.Hg. These readings achieved max vacuum within 10 min. 3. I have coated ALL connections with liquid tape while on vacuum. 4. I have loosened the door hinges so that the door barely hangs on the unit and is pushed into place when vacuum starts thus hinges not hindering the seal. I have sprayed cleaner into the vacuum sensor and rinsed it out. Nothing up to this point has done anything. If I run the chamber empty, it achieves vacuum within 12 min. If I put the tray holder (plugged in and not plugged in) or just a single empty tray into the chamber it will NOT achieve a 500 mtorr vacuum. My next thought is to replace the vacuum sensor. Anyone have any other ideas?

I bet your frustrated. I would be and have been. Using a Hg/in gauge will only give you a rough measurement of vacuum. At my altitude the best I can get is 25 hg/in. You need to think metric in this case, it's almost like thinking backwards. you need 1/2 mm of vacuum. See this video to help you understand: kzfaq.info/get/bejne/es18pbCemrGtl5s.html First of all you need to find out what your vacuum pump will produce in microns at the pump's inlet, then at the end of the hose. It sounds like you have covered all the bases of finding leaks. If your pump can go under 500 mtorr and you have no leaks, then you may have a software issue. What software are you running?

When I close the door, there is NO solid visual ring. The ring touches the glass and shows only on the hinge side until I latch it and it disappears. I have adjusted it both ways to no avail. I cannot get that side to show the ring. I purchased a new door seal but nothing changed. I even all but removed the hinges so that the door is just barely hanging on, turned on the vac pump and pushed the door until the vacuum pulled it to. It still did not achieve vacuum. It is like the drum has been ground uneven. I do not know how to test for that. When the vacuum pump stops the vacuum changes fast like there is a major vacuum leak. So it could be the drum. I put a straight edge on the door and the door shows about 25 thousands or so bow. I turned the door around inside out and ran it but the seal acted the same way and could not achieve a vacuum. Concerning the gauge. I bought it because it had mTorr reading on it. It reads 35 mtorr at the pump and 40 mtorr at the drain valve.

So happy to have found your review with actual testing. I have only purchased Wallaby and have marked OA on containers I sealed using them. It will be fairly easy to snip a corner add some absorbers with enough power to do the job, then reseal. Have you tested the impulse sealers. I have been looking at reviews stating that the temperature knob was flimsy and even came off, temperatures were not stable and some units got hotter and hotter. Safety is my priority. I was comparing features and looking for temperature control by the degree (not 1-5, 5 is hottest). Also, looking at cord length, does it have a stand, width of seal 10 or 15 mm, unit width (8, 12, or 16 inches of heating element), material (stainless steal over plastic). Everyone would be very thankful if you would do a scientific testing and review on the impulse sealer available online. I am looking at the squeeze and release style rather than the one that looks like a giant stapler. Others reviewed those and said that they did not last very long. Maybe 50 seals.

Basic engineering principles will always support a pressure vessel of a spherical design. Why start with an inferior design? The moisture coming from the freeze drier and entering the vacuum pump is acidic (PH scale). Without the protection of oil it will be a matter of time before bearings and machine surfaces begin to corrode. Not all moisture is trapped on the chamber wall. Only an inline cold trap would prevent this. No home freeze dryer uses a cold trap. Oil-free vacuum pumps are a bad idea and shouldn't be offered, or used by, any freeze dryer manufacturer.

@@Philat4800feet The statement "Oil-free vacuum pumps are a bad idea and shouldn't be offered, or used by, any freeze dryer manufacturer" is just insane. There are SPECIFIC oilless pumps designed SPECIFFICALLY for the food industry. I would agree if your statement had included "Just any oil-free vacuum pump is a bad idea". All I'm going to say is in high quality pumps, designed for this specific use, there are special anodizing coatings which are applied to the rotor surfaces that protect said surfaces from such acidic exposure. The bearings are SEALED which protects them as well. That's why there is little chance of contamination. You might want to contact a high quality pump manufacture before you give 'internet' reasons as to why an oilless pump shouldn't be used. Your assumption that all vacuum chamber designs that aren't round are inferior. Yeah, that's ridiculous.. This conversation is going no where. NASA uses SQUARE and other odd shapes for vacuum chambers, I guess they are ignorant as well. It is stated that the Cube is square because it is more efficient by not having as much wasted air space between the square rack and a round vacuum chamber in other dryers- once again read the available literature. Main point - don't trash someone else's design based on so called 'reliable sources' in which you cant even name. All of these points you make are 'internet talking points'. I talked with 2 engineers of the Cube and learned more facts about it in 5 minutes than you have in this entire video. No one is arguing that square is stronger than round when the same materials and construction methods are used. Even a middle school student knows this. The problem is that you dishonestly apply YOUR assumption to the Cube's engineers assuming and dishonestly implying that that's how they designed and built it - using a middle schooler's skillset and level of education along with an inaccurate animation which is totally false and misleading in reference to the Cube's construction.

If you freeze dry the yolk whole, could just boil the yolk with out dehydrating first. Like starting with Coldwater and start heating to a boil?

Unknown. Not sure what that would do to the proteins when frozen.

I don't have that problem, food in pump oil, I have pump oil in every batch of my food! Harvest right refused to help me! Machine is worthless, contaminating all my food.with pump oil! Will this filter out oil in other direction? So basically, these machines are useless. They grow mold abd bacteria, and contaminate your food with the moldy pump oil. What a waste of money. Ive opened 3 month old veges freeze dried w this machine then vac sealed in glass, and it smells so putrid it cant possibly be eaten! I should have the food tested, ill bet its not safe to eat!

Sorry to hear your woes. It sounds like the check valve, inside your pump, is allowing oil to seep out and back to the chamber. Is this correct?

How good are you with your hands? Can you take apart the check valve, clean it, inspect it, and put it back together? and then clean the chamber, rack, hose, etc. with isopropyl alcohol 70%/30% water? I want you to get everything really clean and let it air out overnight.
@mrpush253221 күн бұрын
@Philat4800feet Hi Phil, well I've already done all that, less use alcohol when cleaning everything. I've washed out the chamber and hoses several times, cleaned the rack well to ensure no oil residue. I run a batch of veg and get oil floating on top of effluent water. Means oil vapor is getting into chamber, and hence on my food. All my finished products get a horrible smell after a month or so even when vac sealed in glass, kept cool and dark. I suppose it's from the oil, no other explanation. I looked for a check valve but can't find one to match the not so typical connections on these units. Thanks.

My owners manual states filter approximately every 20 loads. Sooner if it becomes dark or cloudy. I'm very concerned after watching this vidio about the food safety of my products. Also HR has not reached out to me about more frequent filtering you mentioned. I would think they should have if only to limit their liability to their customers. Thank you for sharing this information.
@Philat4800feet21 күн бұрын
For those who run their FD a lot, it may not be a problem. The concern would be those who run their FD perhaps monthly and let the oil idle for long periods of time.

I changed oil in my freeze dryer every 20 batches using the Robinair oil! I ordered a gallon of Black Gold and was going to start using it because of all the moisture problems, my oil looked like that stuff Phil was just showing, I never got to try it, the pump failed on the last batch! The new pump is in route. I will take Phil's advice and change every cycle! and use the Black Gold. Total batches on that pump was 163 or about 5,215 hours with a average o 32 hours a batch

@@Philat4800feet I know I asked you recently what oil you used and I bought a gallon.It failed on the electrical side, it started and ran for a couple of minutes and stoped then it started again and ran a couple of minutes and quit! I unplugged it and plugged it in a different outlet to make sure it wasn't the Harvest Right problem It has gave me fits with water in the oil, when I would change it the oil was nasty and would never separate , I only ran about 163 or so batches, but I don't know how long these pumps are supposed to last! I have the premiere pump.

Why all the fittings? Just screw the FM JIC into the filter and not use all the pipe. Use pipe dope not tape, don't over tighten and mine works fine but never gets dirty. Under vacuum their is no vacuum movement in the chamber and the crud is not directed to any one place, it just sticks to the ice. Another way to cut down on crud moving around is to wrap the tray holder to not only hold in the heat but any crud that may pop off the food.

Yup, I'm sure there's a better way. Blue Alpine has their filter inside the chamber. Simple and elegance.

Good evening Phil I was looking at another freeze drying group and somebody on there said that the oxygen absorbers that you get with your freeze dryer from harvest right are 700 cc and that that is too big of an oxygen absorber that it will make your vegetables squishy. I didn’t think that sounded right to me but I wanted to ask your opinion. can you have too big of an oxygen absorber in a mylar bag or a jar? Thank you for your time.
@Philat4800feet21 күн бұрын
HR went from a 300cc to a 700cc around 2022. an OA will stop working once the oxygen is depleted. OA's will not add moisture to the food contents of a mylar bag, but how do you prove that to someone who has made up their mind? If there food went squishy it's because it wasn't dried enough.
