just because this thread is still fresh and i am seeing 2 very interesting machines right at the start with and even more interesting price tag.

are these two the to-go-for machines one should buy when getting into the chamber topic or are there other  better/ cheaper alternatives?

thanks a lot in advance!

In all the research I've done those are your two cheapest bets,  the 115 is a dry-piston pump and the 215 is an oil-pump.  The more expensive ones come down to features (or branding).  As long as you understand the limitations of any of them as well as dry vs oil.  You'll likely come back to these 2 as options representing the lower end cost wise.  Also the more expensive ones can be slightly lighter as these are not light machines.

Also keep in mind some other features which vary significantly from model to model: the width of the seal bar, the dimensions of the chamber, and external hose port.

I like the 12" seal width of my VP112.  I tend to use larger bags than I originally anticipated, so I also appreciate the length of the chamber.

I wish the chamber height was a little taller, so it could accommodate a 16oz wide mouth mason jar (it's just a tiny bit too short for that).

I use the external hose connection to vacuum seal mason jars... very handy storage containers.

Have you tried the Collection Elite pint jars?

They're wide mouth and only about 3.75 inches tall with the band on.

DDF,

 

I had never seen that size before... I just ordered a few and they will likely work out well.

Any possibility that someone will do for vacuum sealers what they did for immersion circulators (make a fully functional one for 80% less money)?

very unlikely.  expensive to pull a vac and have a chamber that doesn't crack nor implode.

I said exactly the same thing in the other part of the thread.

 

 

despite the naysayers, I predict it's a year or two away (maybe not 80% less, but under $300)

 

 

 

they said the same about immersion circulators

Due to some unexpected tax refunds coming my way, I'm thinking of getting a chamber vacuum sealer.  Probably the VP112.  Is webrestaurantstore still the least expensive?  Anybody in the SF Bay Area looking to upgrade and wants to part with theirs?

I have just purchased the Polyscience 300 chamber vacuum sealer. So far, I am quite happy with it, although I need some tips for sealing liquids. Has anyone else yet purchased this unit?

I've had good results with sealing things for sous vide cooking, and since this is my first time owning a chamber vacuum sealer, the first thing I did was compress fruit.

Hi, imafoodie.  Welcome to eG.

 

I'm jealous - I want a chamber too!  I think the two main considerations for sealing liquids are having an angled surface inside the chamber so the liquid doesn't spill, and the temperature of what you're sealing.  You probably already know that boiling point drops as pressure is reduced, so if you try to seal anything much above room temperature you may end up with it boiling all over the place.

 

Good luck - let us know about your experiences.

Stuff at room temperature boils. Chill it before sealing.

I have mine on order for delivery in about ten days.  It was that or a digital scale.

 

How high a temperature are the Polyscience bags rated, if you know?

I don't know, Jo, about the bags. But it says the bags are BPA free & safe for sous vide & microwave cooking, in case that helps.

Thanks, I'll plan to check with Polyscience once I get my machine.  I'd like to be able to use them in the pressure cooker as well as other things.

The pump is the cheap part. A $20.00 tire pump can be easily turned into a vacuum pump. I have done it.

 

 

It's all the other controls, heat seal, etc.

Normal sous vide bags won't work in a pressure cooker. You'll need retort bags for that. Not all chamber vacs will seal retort bags.

Not quite. That pump isn't going to be strong enough to pull the sort of vacuum that chamber machines are capable of. It wouldn't, for example, be able to boil water at room temperature or compress plant material. The pump in the video you showed is more akin to the pump inside a FoodSaver/edge sealer rather than the ones in a chamber vac. There's a reason that commercial chamber vacs weigh 100lbs or more... the pumps are huge. Chamber vacuums also keep the air pressure the same on the inside and outside of the container being sealed. Since the entire chamber is being evacuated (and not just the inside of a bag or bottle) it's possible to pull a vacuum on liquids wiithout them being sucked into the pump.

I paid $3 for a vacuum "pump" that'll boil water at room temperature (actually much less than room temperature) and compress plant material......a faucet vacuum aspirator.

So far, I prefer the faucet vacuum aspirator for such tasks rather than the chamber vacuum.

Help, please!  My Polyscience came today and I am confused (as well as totally exhausted from uncrating and trying to carry it).  Most of the instructions make at least some sense, but for the following:

 

"Lay bag flat in the vacuum chamber with the opening of the bag across the seal bar."  So far, so good.

 

"If packaging relatively dry products, use one or more of the volume plates supplied with your unit to keep the top of the bag level with the seal bar."  What is "relatively dry"?  And what is a "volume plate"?  I have gone through the packaging multiple times and cannot find anything that might reasonably be a volume plate, nor are volume plates listed in the package contents.  Imafoodie, did you get a volume plate with yours?

 

"If packaging a bag containing liquids or wet product, use a liquid tray and keep the bag below the height of the seal bar."  This seems reasonable, but what is a liquid tray?  I thought it might mean something like a quarter sheet pan, but a quarter sheet pan doesn't quite fit in the chamber.

 

"Secure the underside of the vacuum bag mouth in the clamp."  This is the hard part.  I don't see anything that looks like a clamp.  Even though there is a very small and useless illustration of the unit with an arrow pointing to "clamp".

 

My dinner is marinating at the moment in the refrigerator.  I hope to figure out how to seal a bag in the next hour or I will be eating late.  Suggestions would be most welcome.

 

 

Edit:  I found a picture of a Polyscience liquid tray.  Nothing like that came with my unit, nor can I find them for sale.

Edit 2:  I may have figured out the clamp.  I'll find out when I try to put my pork chop in.  The manual for the 300 is not that good but it's in French as well as English.

"Volume plates" usually look like a white poly cutting board.

 

Have you seen this video?

      I have been tasked with putting together a team for a new kosher barbecue event in Arizona, happening sometime later this year. The event was supposed to be in mid-April, but the venue decided to cancel. The organizers are busy looking for a new venue, and have assured us that this will happen.
       
      Many details for the event are not quite settled yet, so, I am trying to prepare for all sorts of contingencies beyond the usual concerns about putting out good food. What is known is that we will be following the KCBS kosher rules. As far as I can tell, there were 10-12 such events held last year across the US. So, it's a pretty small world. I don't think there's a kosher championship ladder like the other barbecue events have, either. I think it's a good time to get in, get practice and see where it takes me.
       
      Now, I've been reading and watching videos online with all sorts of info on smoking/cooking for competitions. I have watched some of the TV shows, and one documentary. It's been kind of a mixed bag in terms of usefulness. No one has posted much about kosher barbecue, so I am making changes to recipes and procedures and running a lot of tests. I currently have access to my home kitchen which is small but adequate, the stove is electric and unremarkable and about 7 years old. It does maintain temperature well, and can be set to run anywhere from 140°F to 550°F.  I also have access to an outdoor kitchen at a friend's place, with a relatively large charcoal type grill. At most of the kosher barbecue events the event organizers provide smokers/grills plus meats and many ingredients to ensure that everything is truly kosher. If needed, my team sponsor is prepared to purchase a grill/smoker which I will need to research once I know I will need it.
       
      I should note that I am not Jewish and did not grow up around any kosher households, so I am also studying some of the finer points about running a kosher kitchen and learning about kosher ingredients. Modern competition barbecue is an odd mix of modernist techniques and ingredients, right alongside ordinary-folk foods like margarine, and bottled sauces.
       
      For reference, the 4 categories for kosher events are: Chicken, Beef Ribs, Turkey, and Beef Brisket -to be served in that order.
       
      So far, I have been running smokeless tests on chicken and beef ribs. Mostly learning to trim the chicken thighs (what a nightmare!) and seeing what happens at certain temperatures and times. I know things will be different with real smoking happening, but I want to see some baseline results so that I know what to strive for. I do have a bunch of thermometers, and have got some basic ideas about writing a competition timeline.
       
      The chicken perplexes me in several ways. First, some of the competition cooks recommend boning while others recommend bone-in. Second, I see some folks injecting and brining, while others maybe do a quick half hour marinade, and even others are full-on modernist with citric acid under the skin, etc. Third, the braise vs non- braise chicken where some people load up their pan with a pound of butter, margarine or a couple cups of chicken stock while others do not. Fourth, The bite-through skin is driving me insane. Some people swear by transglutaminase to reattach the skin for a better bite. Catch is, only some types are kosher, and I can see having issues explaining it. I have tested an egg white egg wash which seems to attach the skin pretty well without showing. I think I need to go for longer times to get more tender skin. Today I did a pan (with olive oil) of six as follows: one hour at 220°, one hour under foil at 230°, then glazed and 20 minutes on a rack at 350°. It was only partly bite-though and the taste-testers wanted more crispiness. I tried showing them pictures and explained that it wasn't ever going to be crispy, that we're looking to go even softer. I am going to run tests on longer cook periods and see how it goes.
       
      I want to ask people about the whole swimming in margarine thing which is in voque right now. people claim it makes the chicken juicy. I know that meat is mostly all about temperatures. I can see how the margarine acts like duck fat in a confit and helps prevent some oven-drying after hours and hours in the oven, but, in the end, isn't it just an insulator?
       
      I've been making corned beef and other brisket dishes for over 20 years, so, I think I have a good handle on that. I will practice it in a couple of weeks. I simply don't need as much help on this item.
       
      The turkey scares me. On TV, I see people dunking it in butter before serving it. This obviously is not kosher, and I don't want to do it with margarine I don't want to present anything in a competition made with margarine, there has to be something better! -Either cook the bird better or find a better dip, like maybe a flavorful nut oil or a sauce. That said, unlike ribs or brisket, it is not traditional to dunk turkey in a sauce.  I went with some friends to a chain place called Dickies to do a little research and their turkey breast was odd and kind of hammy. Not like Virginia ham, more like ham lunchmeat. It was very moist and unlike any turkey I have ever eaten. Ok, I admit to not being very fond of turkey, so my experiences with it have been a bit limited. I am assuming it was brined. Given the limited amount of time we will have (about a day and a half) to cook, I am planning on just cooking the breast. Other than that, I am open to suggestions. The internet has been least informative on the topic of turkey. People's videos and such just show rubbing the whole bird and letting it roast for a few hours. Any tips at all would be appreciated.
       
      Whew! Thanks for reading all of this, I look forward to any advice you can give.

      I've had the CSO for a number of years now, but have yet to actually bake bread in it.
       
      Reading through the Modernist Bread thread on this forum I see many of you are using the CSO to great effect, which is heartening.
       
      To that end, I would like to know about your experience baking bread in it – what sort of extra equipment you use (pans, cast iron? etc), what breads work the best, any corrections you find yourself making, or anything you feel might be useful to someone else using the CSO.
       
      Thank you!

      The space race trickled into kitchens in the 60s and 70s, including one curious tool that's faded away in the years since: the thermal pin, a heat pipe skewer that can halve cooking times for roasts:

       
      Heat pipes are thermal superconductors, transferring heat 500-1000 times more effectively than solid copper (some people in the sous vide thread have discussed copper pins). They're hollow tubes with the air evacuated and a small amount of working fluid, often water. The usable temperature range is limited by the triple point and the critical point, with additional constraints near the edges. Water is effective from 20C-280C /70F-530F, which comfortably spans most cooking temperatures.
       
      Modernist Bread has an excellent section on how bread bakes, including a diagram of the internal heat pipes that develop, summarized here. (click for a good photo!)
       
      Sous-vide solves the overcooking side of the gradient problem, but it's still limited by total heat diffusion time-- doubling the size of a cut quadruples the time needed for the center to reach temperature. Heat pipe pins should make larger cuts practical, or normal cuts cook faster. Here's a graph from "The heat pipe and its potential for enhancing the cooking and cooling of meat joints", showing average temperatures over time for 1kg joints of meat convection baked at 190C/375F for 110 minutes (foil removed for the last 30 minutes):

       
      Thermal pins were sold commercially from 1956 to about 1990. They're listed occasionally for about $20 on ebay. They even made potato baking racks with heat pipes-- though now you can easily par-cook a potato in the microwave and finish it in the oven.
       
      I don't know why production of thermal pins stopped, or what fundamental problems limited their usage. It seems like pans and commercial griddles would be improved by adding heat pipes to spread heat throughout and avoid hot or cold spots. Perhaps roasts fell out of favor as the culture of entertaining shifted away from monolithic centerpieces to smaller, more precisely cooked portions.

      Hey there, i hope to find some help in the wise hands of yours. after some research i am still having some problems concerning glazing:
       
      For a party i would like to make some cubes and rounded savoury cakes and foams out of silicone forms that have a ready bottom and a colour glazing. 
      Somehow i just do not manage to find a steady glazing ( one that does not run ) and is for texture reasons preferably hard or crisp that does not include sugar or syrup.
       
      can you help me or lead my way in a certain direction?
       
      thanks very much!

      Is there a discussion in the book about the purpose of adding ascorbic acid?  I just saw the contest #2 in which the recipe called for it.  I'm curious because a woman I know on the internet used to work in a bakery in Vietnam, and said that to get similar results to the banh mi there, you need to add ascorbic acid.  Does it act as a gluten relaxer?  Traditional banh mi have a very tender and crisp crust, and a very light and tender, relatively closed crumb.
