Hi Virgilio,

      Do you still have these ? I am looking to get the 60 Kg unit.

     Thanks

      Best

Hardly used filling machine, We used it for filling out chocolate moulds before moving to get cooled.

.33 oz to 10 oz piston filling machine adjusts by moving knob in the back. 

 Had a temperature controlled cover made to regulate the hopper to accommodate tempered chocolate, set it desired temperature about 30 minutes before using for production.

Hopper can hold 30lbs or chocolate

Full pneumatic control, easy to operate, manual or automatic,  we only used the manual foot pedal, easy to

easy to disassemble and clean, parts commonly found at plumbing/hardware store if replacements are ever needed

Single filling head,   but had a four-way heated dispensing plate made to fill two chocolate bars at a time

Asking price $1800 OBO

Thanks Sue!  This looks exactly what I need!  And they have a lovely range of other products too that look really exciting!

Thanks a million!

Try Chicago Mold School they have silicone sphere molds all sizes

My pleasure!

I have a bunch of Ateco-brand spatulas that I am very happy with.

Hey guys, i'm in the market for a good set of offset spatulas to buy. I have a good budget so I want some good quality ones, amazon reviews are tricky to trust these days so I wanted to ask some pros!

Any recommendations?

Cheers!

Thank you Clay !

My one final, final idea is to buy some cheap food grade silicone to make your own mould and pour it over a few dozen marbles/ball bearings of the right size or 3D printed spheres or something like that, glued down. spaced closely and not poured too deep you should be able to get a lot of moulds from around a 2kg silicone mix. 

There are a 2 methods you could use.

Put them half in clay, pour silicone over, remove clay, pour silicone over second half and then fill both halves and then fuse them together once set with some extra chocolate. 

Or just glue to a base and squeeze out them through the small gap/make the gap bigger with a scalpel. 

I won't come up with any more ideas! 

Hi @peter3.  Yes - that is exactly what I wish to do.  I already have a range of "Chocolate Nibbles" and these are created by starting with "callets" of chocolate which are small half-spheres that come from my chocolate supplier.  I pop these into my pan and add a tiny bit of melted chocolate.  The callets then "double" on the flat side and then I can build from there.  They are popular and easy to make.  I do about 60Kg at a batch.  However I want to do something with a completely different chocolate that sadly ONLY comes in 5Kg blocks - not callets. So I'm basically trying to make either callets or balls from the 5Kg blocks to get me started.  On close examination now it is clear to me that the callets are made by depositing but depositors are big and very expensive.  So I wondered about making balls with moulds (molds) but no-one that I can find has small ones.  They all seem to be 20-25mm diam.  Far too large for me.  The "completely different chocolate" is sugar free - so I can't use the callets I use now as they have sugar in them.  I'm a bit stumped.

If I understand correctly you want to have a solid chocolate  centre for panned product?

Are you going to use the same chocolate for both?

We have tested starting a panned product from a very small chocolate drop (like a small piece used for chocolate chip cookies), if you start building the chocolate up around this "seed" very slowly you will get a round ball and avoid doubles.

Once you have your centre you can do with it whatever you want next: sugar coat, pan with the same or different chocolate etc.

Thanks for the thought @garfoid  That's "panning" and where I'm trying to head towards once I have the balls worked out  Let me ponder.  Thanks again.  Colin

That's what I'm doing​ now.  In the winter, they dry out perfectly after a day.  In the summer, even with a dehumidifier in the room, after 6 hours they're sticky.  After a day they're unsellable.  I don't think the dehumidifier is strong enough to get the whole room so I'm wondering if a much smaller area might work.  

Sure, I mean buy a portable dehumidifier and store it in the winter? 

That's not working during the humid months.  In the winter that's fine.

The only method I can think of is a tumbler style. Putting all the chocolate cubes into a mixer and letting it tumble like a cement mixer. They may stick together so starch could be used, but i'd imagine they'd get round pretty fast and this wouldn't take too long. 

Best of luck! Let us know how it works out? 

Hello, Are the displays still for sale? You mention that they are 48" in length but your photo makes it look like they may be a bit longer? Can you confirm the length of these? 

Where are you located? Do these need to be picked up or are they ready to ship? 

Thanks!

Thanks for the thought @garfoid It MIGHT be a solution.  It would be slow and I need to do runs of around 16Kg at a tine.  I think that each ball will be about .7gm so I think that is around 2,300 balls per batch. Also I will be further processing these with panning and flat edges tend to "double" although if I could cut them into cubes I might work through that.  Appreciate the thought.  Will think about a guitar - had not considered that route.

Why not dehumidify the whole room? To save building a box? 

Couldn't you cut the blocks into the rough sizes you want and then, with gloves, roll it into balls like truffles? Keeping your hands hot might just round the corners to give you a sphere shape? Failing that, do they have to be balls? Can't they be cubes? 

Hi All!  I need to make a LOT of small chocolate balls. Say 10mm diam. I had been panning callets but a project I'm working on only has bulk chocolate in blocks.  I only want chocolate in the centers.  I've spent hours seeking moulds on web sites world wide but can't find anything.  Even if I can only make half spheres that would get me started.  There are spheres and half spheres 20mm and up but I really want them smaller.  Any thoughts please?  Thanks!

Clay,

Thanks very much for that helpful reply.

Jim -

In purpose-built fridges the purpose is all about short recovery times. Getting back to the desired RH and temp quickly when the door is closed.

The larger Everlasting fridges, in part because they are deep and narrow, recover very quickly. It's also one of the reasons I recommend the double-door version as this reduces recovery time.

Another aspect of these purpose-built fridges is the circulation of air. It's designed to remove the latent heat of crystallization efficiently. (And the humidity.)

You can't use an external controller for temp as when you turn on the fridge (at least many commercial fridges) the first thing they do is go into defrost mode.

H'mm. Thank you for sharing this. I really appreciate it. Since the smell comes from fermentation, and that produces acetic acid, I wonder if the bags could be washed in a tub of baking soda (a base) to counteract the smell. Anyone tried this? I would be happy to try it if I can get any of you chocolate makers to send me some bags. I will pay!

I am not sure if you are planning on using real used cocoa bags but I would caution you on this. I purchased some from BurlapFabric.com expecting to do the same - decorate my store and it was a HUGE mistake. Since the fermented beans are shipped in these bags...they stink to high heaven. There was such a bad smell from the cocoa bags that I had to store them in my garage until I figured that even washing wasn't going to save them. I ended up having to toss all of them.

They were super cool to look at and seemed like they would be great decor but in the end I was told from other chocolatiers, the smell in the bags is pretty common and does not come out.

Still interested in the cutter

I have done some more reading on RH in refrigerators, and what I read is not conclusive. Apparently fridges with the door shut for a while have a very low humidity level, but when the door is opened, the RH goes up quite fast. I roughly verified these observations with my hygrometer. Are there ways in which a cooler specifically for chocolate would operate any differently? In other words, why wouldn't placing a mold with crystallizing chocolate raise the RH same as a regular fridge?

I'm doing some redecorating in my shop and an interested in using cacao bags for decor. Please shoot me an email at info@stcroixchocolateco.com with what you have and what you'd like for them. Interested in wide variety of origins. Thank you.

I have been told that about 55F (about 13C) is a good temperature to start with. RH about the same 50-55.

The Everlasting 130 with a glass door is about £2700 plus shipping. Stainless steel is about £100 cheaper. Takes about 60 days from completion of order. It's 220V single-phase, no 120V option, so might not work in a home environment. The load is pretty low so you might be able to use an electronic transformer designed for appliances with reactive loads (e.g., refrigerators with compressors).

Clay,

Thanks for the helpful response. I have the Moso charcoal bag in a wine fridge, but I have never been convinced it did any good. I'll test the RH with and without it. What you say about chilling a mold in a sealed plastic bag confirms what I suspected, so I guess that idea is out.

I have just reread Peter Greweling's section on the latent heat of crystallization. He mentions refrigerating the chocolates to help with the problem but cautions that the temp (he specifies as 51F [corrected 7/6/17: Greweling specifies 41F] as ideal) and humidity of the fridge should not be too high (easier said than done in a home situation).

Can you provide an approximate cost of the Everlasting 130 (mini cooler)? I have seen that Hilliard's also makes a chilling cabinet, and although I expected the cost to be substantial, it was higher than I anticipated.

@chocotoymaker -

It's in section 3.14 of the following document:

@jim-dutton - 

To the extent that you reduce the amount of moisture in the immediate environment that can condense on the surface - maybe. However, the labor and time involved may not be worth it.

However, airflow over the surfaces of the mold (there is a fan in the fridge that works all the time, right?) are key to removing the latent heat of crystallization and so containing the mold as you suggest would certainly slow crystallization down, could interfere with it - reducing the quality of the temper, and might not solve the moisture problem.

First thing is to know what the RH in the fridge is. If you don't want to invest a lot of $$, try something like a Moso Natural charcoal bag or something similar just to see where that takes the RH to and see if that solves your problem.

I don't usually attempt much chocolate-making in the humid summer months, but my business appears to be expanding, so I am trying to cope. The air conditioning in the house (I am a home-based operation) removes enough humidity to get the RH in the 40% range, but when I put the molds in the fridge (to take care of the latent heat of crystallization), the humidity is considerably higher. Before I give more serious thought to a humidity-controlled cooler, I was wondering if this very low-tech procedure would help: Once a mold is prepared with chocolate and the chocolate has begun to crystallize, I could seal the mold in a plastic bag (not vacuumed, just sealed with an impulse sealer) and put it in the fridge. This would take a little time, but it would be easy. My question is whether it would work: does a mold have to be open to the air for the latent heat to dissipate? 

Have you sold your Prima yet?  

3d print the positive and seal with an epoxy resin. Then make the negative using food safe silicone. I tried using 3d printed abs as a test run for personal use. Cleaning it was a nightmare and heating and cooling warped it. Not to mention the potential bacteria growth in-between poolry sealed layers. It's much easier, faster and more reliable to print a positive, have a low infil and then do what I said. If you have a very soft silicone it's even better since you can get away with having a single piece mould rather than a two piece. The key is 100000% in the prep of the positive. If you rush it or use the wrong resin to seal it you end up with the lines transfering into your moulds and then chocolate.

By sealing I mean sealing the ridges of each layer. Anotjer option I've explored is vacum forming using APET Plastic. It's food grade and usually comes around 5mm thick so it's dead durable. But it's expensive and requires a beefy vac former.

I came across Cooler King and am trying to understand it.  It seems to be a product, good for 3 months, you place inside your refrigerator?  But it appears to be a service business as much as a product, is it similar to getting bottle water service?  I figure if that is the case the chance that we have that as an option in Montana is not great.  I will look at the other one you mentioned.

As to sourcing the refrigeration options, I would be happy to take a look.

Thank you!

The major issue is managing humidity if there is a temperature difference between the room and the cooler.

There are static options.

One is Cooler King from PolarFresh:
http://www.polarfresh.com

Another is HumiClear:
http://humiclear.com

The great thing about static systems is that you can retrofit them to any existing cabinet (e.g., wine fridge).

However, if you are interested in a new cooling solution with built-in humidity control, the fridges from Everlasting are very good and I can source them for you.

I use these and they are perfect.

I also use a wine fridge (actually I current have 2), but you need to find one that is able to maintain a consistent temperature. The first one I had fluctuated so badly that it couldn't really be used for chocolate OR wine.

One more edit: the humidity is surprisingly high in both fridges but I guess because the temp is higher than a normal fridge its not such an issue.

My spouse does some home brewing.  Looking at his equipment options he says there is a dehumidifier of some type that he thinks could be used with the refrigerator.  I need to look at that to understand how it works.
