Chamber Vacuum Sealers, 2014–

Recommended Posts

Me again with as mall but hopefully not too stupid question: i have read the very interesting Dave Arnold article on cooking issues concerning the level of vacuum changing the texture of meats. My question now: how do i define the vacuum level on chamber vacuum sealers? Since i do not see any Option on programming the vacuum percentage on most machines we are talking about. Is this done through the time or how? Thanks a Lot!

I finally received my 35XP a few weeks ago and have been using it extensively. Having lots of fun with infusion and compression, some cucumber and red radish pickles I made this past weekend with aged sherry vinegar on a 5-minute infusion cycle were a particularly noteworthy success.

 

I have however been having one seemingly minor issue with the conditioning program, which has the rep at Testek stumped...waiting for some more information from Minipack themselves. Specifically, this always fails on the first run with a "SERVICE - VACUUM TIME" message with exactly 2:39 left on the countdown clock. If I run the cycle again immediately, it seems to always succeed the second time.

 

Any other XP-series owners run into something like this with their unit? It seems a relatively minor thing, but I'd obviously like to rule out that it's a symptom of some more serious problem.

I also have totally random issues with my MVS31X - My issues seems to stem from the machine's display getting stuck on a digit, say 94.5, and the machine running until error -- That is, unless I gently tap the display, at which point it will jump up, eventually to 99.1 and count up from there. I just had the entire vacuum pump professionally cleaned after it died last fall, and this new and interesting issue has arisen. It basically worked like a charm for 2 months and then this came up. I haven't heard of too many other problems with people and their minipacks -- I wonder if I got a touchy machine -- It isn't as if I use it all the time either -- I probably use it 5 times (max) a week.

@danelks -- Maybe we both have wiring issues with our machines? That is really the only thing I can come up with.

@Unpopular Poet - wiring for my issue seems less likely but I can't really rule it out - faulty wiring would I'd assume cause the same failure each time. Since the XP series have a more complicated embedded microcontroller I'm thinking it's more likely to be a programming fault...

 

I will follow up to the thread if and when I get more info from Minipack.

Tonight I'm trying to use the Polyscience 300 to pickle coleslaw in the Polyscience 2.5 quart canister.  The first problem was plugging the vacuum hose into the unit so that it would actually pull a vacuum.  Had a similar problem with a Diesel Jeep once.  Next problem was the Polyscience instructions say the marinate preset, P3, has a factory vacuum level of medium.  But for me the factory setting of P3 seemed to indicate it was using the minimum vacuum level.  I over rode and set the vacuum level to medium (57 Torr).

 

The instructions for canister marinating say to set the canister vacuum port to the "Open" position.  When I did this the valve seemed to hiss as vacuum was applied, so I set the canister to "Vacuum" and ran through the modified P3 cycle, which takes 27 minutes.  However the canister did not seem to release vacuum, so I concluded the instuctions may have been correct (at least in this case) to set the canister to "Open".  So I did so, fiddling with the control a bit, and ran the cycle a second time.

 

The marination is about done and I will try the coleslaw in a few minutes.  Though I have a feeling my procedure is probably still not right.  Can anyone give me suggestions?

With the Polyscience 300 is there any way to hold the vacuum level after the vacuum time expires?  I ask because it is so neat to watch ice water boil.

 

There is a cuisine related issue here but that does not detract from how neat it is to watch ice water boil.

The Polyscience 300 lets one program vacuum level based on time, for which the manual gives equivalence in Torr and inches of Hg.  There is also a correction for altitude above sea level.

Hi I´m trying to find info on the Brand ¨Basser Vacuum¨. Does anyone have references about their products?

Is an external aspiration model, What is the general opinion about this kind of vacuum sealers?

I´m planing in buy the Fresh33 model, for a small business i´m starting. I´m doing beacon and duck ham.

 

 

 

Thanks

Rodrigo

From what i ve heard they did produce the complete edge sealer range of German company allpax people are extremeley happy with, specially hunters. Since they do use bosch Pumps aswell i think they will do quite a good job in the chamber vac area aswell?

I haven't had that problem, though I have only used the conditioning cycle a few times. (How often are you SUPPOSED to do it, do you know?)

 

I have had a different issue, though... Has your display ever gone completely blank, or half blank? 

 

Don't hesitate to call Minipack directly. There's a very helpful tech there named Jamal, who I've spoken with a couple of times.

I've just been keeping an eye on the oil and running it when it looks cloudy from water vapor. Depends how much you seal liquids, I think.

 

I haven't had that problem in particular. I have been talking with someone at Minipack actually, but they haven't come up with much yet...still back and forth.

While I am still pleased with the Polyscience 300, I find it does have a fault. When draw a vacuum using the external vacuum port, sometimes it works and sometimes it does nothing (even though the machine pulls a vacuum inside the chamber). I'd say more often than not the external vacuum feature does not work.

 

I think the problem has to do with how the supplied vacuum hose fits -- or doesn't fit -- in the vacuum port. It may of course be user error...not helped by the wretched Polyscience 300 manual.

 

Any advice or thoughts?

I'm planning to modify my VP215 to add a digital vacuum gauge, and program for seal at %vacuum as an option to time.  After that mod, I will consider adding MAP gas venting and/or an infusion program.  I have not been able to find any posts on this modification.  I can't imagine someone here has not already done something similar...  Have I missed anything?

For all of you Minipack MVS35XP owners out there -- how are you enjoying your machine -- I have the capability to possibly upgrade to it at this point and I am thinking that I will.  I have a MVS31X, which is great, but I find that time and time again, anytime I do a hot or liquid application, I end up messing up the pump -- Currently the machine says it is pulling 99.9, but I know from experience is quite a bit less.  Perhaps even in the low 90s.  Thanks for the input....The other item I am looking at is the Polyscience 300 -- but I may be in the same boat with liquids and hot items.

I've been quite happy with my 35XP. I abuse it with hot foods and liquids all the time and the pump is still going strong. I just changed the oil though, at about 550 cycles, because it looked milky... I wish knew how often you really have to do that because at that rate it adds about two cents in costs to each cycle.

horseflesh -- that was exactly what I wanted to hear -- Now if Polyscience would just call me back...

I too am very happy with my 35XP, aside from the odd issue with the conditioning program (which is still an ongoing discussion with MiniPack - it appears I may need a replacement control card). I use the soft air and infusion cycle so frequently that I can't imagine not having them.

 

Horseflesh, for what it's worth, running the conditioning program tends to get rid of that cloudy/milky consistency in the oil. I think the manual suggests replacing the oil after a certain number of cycles but I don't remember the total off the top of my head. The machine keeps track of that for you buried somewhere in those menus...I intend to replace the oil no less than once per year though, even if I don't hit that total. Better safe than sorry.

I've used the conditioning program a few times but haven't noticed a visible difference in the oil. That may be meaningless, though. 

 

Do you have the manual soft air knob? Mine came with one and I have honestly never tried the programmable soft air, since the knob is so darn easy to use. 

 

Any other problems with your unit? Mine does have a quirk--the display may go blank, or just half blank, until you power-cycle it. This only seems to happen if I interact with the control panel, eg changing programs, and then only if I leave it alone for a while.

 

If I just turn it on and operate it, I don't think it has ever blanked out. Makes me think it may be a software problem... Minipack suggested opening up the unit and re-seating the cables, which I have not yet tried.

I've definitely seen relatively cloudy oil become crystal clear after a couple of conditioning runs (you need to let it settle for a few hours afterwards, as it will draw in a lot of air).

 

No soft air knob on mine, just the software program. I imagine we must have different revisions.

 

The only problem I've had is the one I described a few posts back, where the conditioning program sometimes terminates early with an error message. No issues with the display that I've seen.

 

It seems given my location I may have to install the replacement control card myself - which I'm actually not too concerned with (provided it doesn't affect my warranty). I wouldn't mind getting a look at the guts of the machine in all honesty.

Well, I went ahead and ordered the MVS35XP from Polyscience yesterday -- It is being delivered today -- gotta love being within 20 miles of Polyscience.  I am really, really excited to see the difference between the 2 (35XP vs. 31X) -- I feel like the pump should make a huge difference -- as well as the soft air, hot food and infusion cycle.  PS - If anyone is in the Chicagoland area and has an interest in a MVS31X (which needs an oil change and pump cleaning which would cost about ~$250?), I would be happy to discuss a sale or interesting trade.  It does have the gas inlet as well, but I have never used that.  Otherwise, I am just going to put it up on craigslist at some point.

      On Nov. 7, 2017, Modernist Bread will finally arrive on my doorstep. Having preordered it literally the first day it was available, to say I'm excited about this book is a bit of an understatement. The team at The Cooking Lab have been gracious enough to give @Dave the Cook and me early electronic access to the book and so I've spent the last week pouring over it. I'm just going to start with a few initial comments here (it's 2600 pages long, so a full review is going to take some time, and require a bunch of baking!). Dave and I would also be happy to answer any questions you've got.
       
      One of the main things I've noticed about this book is a change in tone from the original Modernist Cuisine. It comes across as less "everything you know is wrong" and more "eighty bazillion other bakers have contributed to this knowledge and here's our synthesis of it." I don't think it's an exaggeration to say that Myhrvold and company are now the most experienced bread-bakers in the world. Not necessarily in terms of the number of identical loaves they've produced, but in the shear number of different recipes and techniques they've tried and the care with which they've analyzed the results. These volumes are a distillation of 100,000 years of human breadmaking experience, topped off with a dose of the Modernist ethos of taking what we know to the next level.
       
      The recipes include weight, volume, and baker's percentages, and almost all of them can be made by both a home baker and someone baking in a commercial facility. The home baker might need to compromise on shape (e.g. you can't fit a full-length baguette in most home ovens) but the book provides clear instructions for both the amateur and professional. The recipes are almost entirely concentrated in volumes 4 and 5, with very few in the other volumes (in contrast to Modernist Cuisine, where there were many recipes scattered throughout). I can't wait for the physical volumes to arrive so that I can have multiple volumes open at once, the recipes cross-reference techniques taught earlier quite frequently.

      Introduction

      Welcome to the index for the Sous Vide: Recipes, Techniques, & Equipment topic, one of the largest and most influential topics on eG Forums. (The topic has been closed to keep the index stable and reliable; you can find another general SV discussion topic here.) This index is intended to help you navigate the thousands of posts and discussions to make this rich resource more useful and accessible.

      In order to understand sous vide cooking, it's best to clear up some misconceptions and explain some basics. Sous vide cooking involves vacuum-sealing food in a plastic bag and cooking it in a water bath at precise temperatures. Though it translates literally as "under vacuum," "Sous vide" is often taken to mean "under pressure," which is a misnomer; not all SV cooking involves food cooked in conditions that exceed atmospheric pressure. (See below.) In addition, calculations for SV cooking involve not only time and temperature but also thickness. Finally, due to the anaerobic conditions inside the bag and the low temperatures used, food safety issues are paramount.

      You can read the basics of SV cooking and equipment here. In the summer of 2005, Nathan Myhrvold (Society member nathanm) posted this informative, "I'm now going to answer my own initial questions" post, which addresses just about everything up to that point. For what came next, read on -- and be sure to order Nathan Myhrvold's highly anticipated Modernist Cuisine book, due in spring 2011.

      As with all indexes of on-going discussions, this one has limitations. We've done our best to create a user-friendly taxonomy emphasizing the categories that have come up repeatedly. In addition, the science, technology, and recipes changed over time, and opinions varied greatly, so be sure to read updated information whenever possible.

      Therefore, we strongly encourage you to keep these issues in mind when reading the topic, and particularly when considering controversial topics related to food safety, doneness, delta T cooking, and so on. Don't read a first post's definitive claim without reading down the topic, where you'll likely find discussion, if not heated debate or refutation, of that claim. Links go to the first post in a series that may be discontinuous, so be sure to scan a bit more to get the full discussion.

      Recipes were chosen based solely on having a clear set of information, not on merit. Indeed, we've included several stated failures for reference. Where possible, recipes include temperature and time in the link label -- but remember that thickness is also a crucial variable in many SV preparations. (See below for more information on thickness.)

      History, Philosophy & Value of SV/LTLT Cooking

      Over the years, we've talked quite a bit about SV as a concept, starting with this discussion about how SV cooking got started. There have also been several people who asked, Why bother with SV in the first place? (See also this discussion.) What with all the electronics and plastic bags, we asked: Does SV food lack passion? Finally, there have been several discussions about the value of SV cooking in other eG Forums topics, such as the future of SV cooking, No More Sous Vide -- PLEASE!, is SV "real cooking," and what's the appeal of SV?

      Those who embrace SV initially seek ideas about the best applications for their new equipment. Discussions have focused on what a first SV meal should be -- see also this discussion -- and on the items for which SV/LTLT cooking is best suited. There's much more along those lines here, here, and here.

      Vacuums and Pressure in Sous Vide Cooking

      As mentioned above, there has been great confusion about vacuums, pressure, and their role SV cooking. Here is a selection of discussion points on the subject, arranged chronologically; please note that later posts in a given discussion may refute earlier ones:

      Do you need a vacuum for SV cooking, and, if so, why? What exactly is a "vacuum"? Click here, here, and ff. Are items in vacuum-sealed bags "under pressure"? Does a vacuum sealer create a vacuum inside the bag? Do you really need a vacuum, or can you use ZipLoc bags? Also see here, here, and here. If "sous vide" means "under pressure," aren't the items in the bag under pressure? There is more along these lines to be found in this discussion.  

      The Charts

      We've collected the most important of many charts in the SV topic here. Standing above the rest are Nathan Myhrvold's charts for cooking time versus thickness and desired core temperature. We worked with him to create these three reformatted protein tables, for beef, fish, and chicken & pork.

      Nathan provides additional information on his charts here. Information on how to read these charts can be found in this post. For an explanation of "rest time" in Nathan's tables, click here.

      Other Society members helped out as well. Douglas Baldwin references his heating time table for different geometric factors (slab/cylinder/sphere) here; the pdf itself can be found here. pounce created a post with all three tables as neatly formatted images. derekslager created two monospace font charts of Nathan's meat table and his fish table.

      Camano Chef created a cumulative chart with information gathered from other sources including Thomas Keller's Ad Hoc. Douglas Baldwin shared this chart devoted to pasteurizing poultry. PedroG detailed heat loss and steady state energy consumption of sous vide cookers in these charts.

      Finally, there is also an eG Forums topic on cooling rates that may be of interest.

      Hi,
      I've tried to make the spherical mussels recipe from the Modernist Cuisine books and it didn't work as I expected, so I would appreciate any advice that may help here.
      The recipe calls for calcium gluconate which I couldn't get hold of, so I replaced it with calcium lactate gluconate that I had at home. I used the same ration (2.5%)
      When I tried to create the spheres in the sodium alginate bath I encountered two main problems;
      1. instead of spheres the mixture just stayed as uneven shape on the surface. The bath was 1Kg. water with 5gr. sodium alginate and I let it rest in the fridge for 24 hours before using it so I think the problem is not here. However, the mussels jus mixture (100gr. mussels jus, 0.5gr. xanthin gum and and 2.5gr. calcium lactate gluconate) had a lot of air bubbles in it. Can that be the issue?
      2. In the book the spheres seem to be completely transparent whereas my mussels jus mixture was pretty white and opaque. Is it because I replaced calcium gluconate with calcium lactate gluconate? Or maybe it's because the jus itself should be clarified before it is used?
      Thanks in advance for your support,
      Tom.

      Good afternoon everyone!
       
      I currently own a MiniPack MVS31x chamber style vacuum sealer and am wondering if a Polycience vacuum canister will work in my machine? The intended use is for making a larger batch of aerated mousse.
