Spraying Chocolate: Equipment, Materials, and Techniques

Recommended Posts

Thanks. The Iwata is listed as 1/8 horsepower max 35 psi. 

 

I saw some other brands on Amazon that were 1/5 or 1/3 hp and up to 60 psi. Do you think that would be enough?

Dammit. Just went to the description page for the compressor I ordered (which should be in today or tomorrow) to refresh my memory on the specs. It should be fine as far as being powerful enough... but I just noticed for the first time that it's 220v. Guess it's gonna be doing a fast turnaround and go back and I'll look for another. I really have to start reading things more carefully.

I feel your pain. I just did the same thing with a non-food related item. Even worse, because it was part of a large order, I now have to find proper packaging and take it to the post office etc. etc.Damn. Must learn to read.

@pastrygirlI have an Iwata SmartJet Pro (IS875) - http://www.iwata-medea.com/products/compressors/smart-jet-pro/

This isn't really high enough pressure. You can make do with it, but I have to pause after each row of cavities and let the pressure build back up. It's really great for spatter applications that use a lower pressure, but if you want easy whole-cavity coverage you'll need more pressure. If I do get the opportunity to upgrade, I'll give the IS875HT a go, unless someone on here has a better suggestion :)

 

Chris,

But you are using a higher-power spray gun rather than a typical airbrush, correct?  That might require more power.  I too have the Iwata SmartJet and don't find the pressure is the problem, at least with my Paasche airbrush.  The issue is more with having the cocoa butter come out in a steady spray.  Mine sprays fine for a few cavities, then I have to stop and heat everything and shake the bottle.  It's as if something gets stuck in the siphon, then gets dislodged.  I have even wondered if the glittery cocoa butter is the culprit (Chef Rubber's "Jewel" product), but the issue sometimes occurs with regular c.b.

Thanks, all, I'll look around and try to resist the ridiculously huge yet relatively cheap Home Depot compressors. Sounds like a little more power than the Iwata would be nice for working quickly but not crucial.

As mentioned mine is an Iwata - also a Smart Jet - and 1/8 HP but the specs on mine read 0-60 PSI whereas all the ones they list on their website are 0-35 PSI for that same size.

Yes, you could be right! I've not had a good enough reason to get a smaller airbrush than the one I was given - freebies always are a good thing ;) There's no branding or anything on the one I have, it's just an HVLP gravity feed with a 100mL canister on it.

So the correct compressor has been ordered and the incorrect compressor is ready to go back to the post office. Anyway, the one I ordered is 1/6 HP, 20-23 liter/minute air flow and pressure up to 60 psi. Should be plenty for my airbrush (Paasche HS) so the only thing that should be holding me back with airbrushing now will be lack of skill. :D

I ordered this one from Amazon, 1/5 hp, up to about 60 psi, and inexpensive. I hope it works!

I think the PointZero, Abest, Pro and a couple others are all pretty close to being the same compressor. Lower cost made-in-China compressors that generally get high ratings in the reviews. I ordered the Pro which looks extremely similar to what you ordered. They have a version with the tank like the one you ordered but I went with the one without the tank. These compressors use 1/8" BSP fittings and most of the common popular airbrushes (including Grex) use NPT fittings so there's a good chance you're going to need an adaptor like this one.

Edit: I just spent several minutes searching the internet for an 1/8" BSP to 1/8" NPT adaptor in Canada and for what it will cost + shipping, I can just order the Paasche D220R compressor (1/6 HP, up to 50 PSI)  instead and be done with it. So I went back to amazon.ca and canceled the Pro compressor. So much for trying to be thrifty.

I tried out the new Grex airbrush and Point Zero compressor today, worked fine with no need for an adaptor (got a Grex hose at Chef Rubber when I bought the airbrush).  Reasonably quiet, like a refrigerator running.  MUCH quieter than the Wagner airless paint sprayer!  Or even my KitchenAid mixer.  Now to practice ...

Awesome. I was assured by several reviews that I would need an adaptor to use the Paasche with the compressor I ordered so I took their word for it. Now I'm wondering if I should have waited and checked for myself. Oh well, what's done is done.

Your public anxiously awaits the results.  If you tell me it went perfectly and you produced beautiful chocolates the first time, I think you should be banned from eG.

LOL!  Um, I might have to invoke my 5th amendment rights :$  Would it help if I tell you I used purple, orange, and dark chocolate and the test shells came out shiny but super ugly?

 

I definitely need to play with pressure and possibly tip sizes, I think the spray was a bit too fine, the color was not very saturated.  And I'm not sure how to get splatter, is it lower pressure, thinner CB, larger tip, or some combo?

Try lower pressure first. Splatter may have to be done with Chocolot's technique using that brush. With my Fuji just turning down the flow will cause splatter but I can't get my Paasches to splatter that way.

Did you have to stop fairly frequently to heat up the brush and chocolate?  That is the problem I have far too often; I have to stop maybe 10 times in the course of spraying a mold.  I'm using a Paasche.  I think I need help (about airbrushing, I mean).

@Jim D. I only did two molds, I was just making sure things worked together.  The little ink cups are metal, so I'm sure as the kitchen gets colder it'll become a challenge.  Re-warming every few cavities would be totally maddening!  I did hit it with the hair dryer a few times just to make sure, but the real test will be trying to do actual production.

I have one of these. I plug it in with an Ikea dimmer switch so it is a little cooler. The little metal cups and the several airbrushes sit on the metal surface with a piece of disposable shop towel under them. Keeps everything toasty and ready to go - saves all sorts of pre-warming with the heat gun.

I already have 3 really good temp controllers that I used for cage temp control back when I had pet reptiles so I'm thinking about just using a small inexpensive dehydrator or something like that and running it through one of those controllers. I figure I can keep my airbrush and color cups in there all the time and just turn it on the night before if I have plans to airbrush.

Hello I am currently looking at https://www.air-craft.net/acatalog/Sparmax-TC-620X-Airbrush-Compressor.html#SID=2025 for use as an air sprayer. does anyone know if this would be sufficient to support an spray gyun also??

I need something very quiet and reliable

 

would this compressor be more suited? https://www.air-craft.net/acatalog/Werther-Sil-Air-50D-Silent-Airbrush-Compressor.html#SID=30

      Anyone have a favorite recipe for chocolate cake using semisweet chocolate?  My usual chocolate cake recipe uses cocoa, but I have some samples of chocolate I want to use up for a workplace party.  Yes, I could make brownies or ganache frosting, or chocolate mousse or chocolate chunk cookies, just feeling like cake this weekend ...

      I'm trying to make bonbons with milk shells for the first time and I'm struggling. When I melt my milk chocolate it is really thick. Is this normal? I'm pretty sure humidity is not an issue. I'm concerned that my shells wont empty out well and I'll be left with no room for ganache. I tried adding some cocoa butter last time but it affected the flavor. 
       
      Disclaimer: I'm using pretty cheap milk chocolate (Ghirardelli) cuz I'm still learning. If you think this is the only issue please let me know.

      We work with transfer sheets regularly but most of them are not double backed. By that I mean most of them are one layer, not backed with a white layer. I'm having a real problem with consistency in the thicker sheets as seen attached. We attach these individually as they come out of the enrober but it doesn't feel like we're getting enough heat penetration to do a full transfer.
       
      Anyone share some tips on thicker applications like these? Our short run came out fine but as soon as we went into production of course the first batch ends up being shot.

      So a question about guitar cutters. I can see why they're a superior method for cutting ganache in terms of uniformity and efficiency, but I was wondering if there's something about cutting with a metal string that's superior to cutting with a knife? Perhaps a ganache would stick to the string less than the knife? Where I'm headed with this is, as someone who's just starting out and not ready to invest in a guitar cutter, I'm wondering if using a cheese lyre to cut ganache might be better than using a knife?

      Afternoon everyone. I know that some of you have taken classes with Melissa Coppel and I am finally going to bite the bullet and take one of her classes, but I don't know whether I should take her "Intensive Chocolate Workshop" class or her "Running a Chocolate Production" class. I hear all of her classes are great, but I'm just wondering which one would be better for an amateur home chocolate maker who is pretty confident in his tempering and ganache skills, but is looking to take that next step. Thanks in advance!!
