Cocoatown Stone Re-grinding

I have no further information. I am continuing to use the stones as they are - 15,000 hours since new.

I have not found an answer nor any community best practices. I will raise the question at the Northwest Chocolate Festival in two weeks.
An almost new Dedy Confectionery Guitar Cutter, 5mm spacing with 3 frames.
It was bought new six months ago from TCF Sales. I have since decided to only produce molded candies so the guitar cutter is surplus to my needs. It was used about 12 times. Below is the description from TCF Sales:
DEDY confectionery equipment presents the 5 mm single arm Confectionary Guitar Cutter that produces true 1" squares. Not to be compared with guitar cutters made with a nylon (plastic) base, Dedy guitar cutters cut uniformly and precisely, and perform precisely not only initially but over time. Cuts most any soft confectionery food products like ganache, pralines, fudge, jellies, soft caramel, almond pastes, etc. DEDY quality is exceptional and preferred by professionals worldwide.
• Base Surface: 350 mm x 350 mm. Made of high quality aluminum alloy for precision and durability, and to minimize weight.
• Guitar Cutter Frames: Made of stainless steel. Three (3) frames included: 15 mm, 25 mm, and 30 mm. o Other frame sizes can be ordered separately, but must be divisible by 5 to fit this base.
• Also Includes: Pick-Up Pan to move food product to and from the Guitar cutter, spare wire, and tools. Dedy Guitar Cutter are easy to use and easy to clean. Simply remove the frame and spray or submerse in hot water using a small amount of detergent as desired. Spray base with hot water and use a firm brush as necessary.

Hello. After two years of constant use, the stones in my large cocoatown grinder is very smooth. The smooth seems to contribute to more roller sticking and less smoothness in the chocolate. Has anyone re-roughened the surface of these stones? Any thoughts, comments?
That is the craziest thing I have heard in a long time. Any good V-Belt can handle a wide temperature range. My car back in Canada would not shred belts at -40. It seems that the alignment is not correct. I would also recommend using link belts.

Hello.
This appears to be the best break through in technology for craft chocolate makers. The price point is reasonable when calculated on a cost/kg processed. It is no different than a Cocoatown as their prices have rapidly increased - close to $10K per unit now.
I would like to understand what (if any) certifications that are planned. In the US, it can be difficult to use equipment that is not UL listed or NSF certified. CE approvals can be used if you can convince your local health department.
Thank-you,

As Sebastian pointed out, this kind of financial information is highly guarded. You should, however, be able to make a generic analysis. It should be pointed out that Mast Bros operation is completely different from Torres - small vs. large factory.
First, what is the price of beans? Bean to bar makers are paying higher than Fairtrade pricing so estimate around $3500/ton. Add in the cost of shipping - $400 per ton. And the cost of sugar - Organic sugar is $2/lb. These are the raw materials.
Now processing: the beans must be sorted, roasted, cracked, winnowed, ground, counched, tempered, molded and packaged. For small batch operation that might take two people, 20 hours and produce 100 lbs of chocolate. For large factory like Torres - no idea as it is a highly automated process. You will have to research the typical cost of employees in NYC.
Equipment: A small factory might have $150,000 in equipment - a large factory $2-$3M. A portion of the cost must be added in along with all the other overhead - sales, marketing, IT, wages, taxes, websites, packaging, maintenance, travel, utilities, etc. Overhead could run 500 - 1000% of the cost of the beans.
From there you can derive the cost per bar - with plenty of assumptions of course. Most of the costs are variable and controllable by the company.
Or use an industry estimate - one book on specialty food retailing said that the typical retail food cost was 35% of retail so a $8 bar would cost $2.80 to produce.
Hope that helps.
Hello.
I have been using the Champion for cracking but I am not so pleased. The major issue is the husk pieces can be quite large which then fall into the nibs. If I increase the vacuum then too many nibs are lost. I am considering adding a coarse screen to the exit of the Champion to catch the large pieces and then re-process those large pieces.
I have another bag of beans arriving this week so I will try this and report back.

Hi. I have been able to conch with the Cocoa Town tabletop grinders by adding a plastic washer under the center shaft. I made a washer from polycarbonate and one from Teflon/nylon. I lift the stones after grinding and place the washer over the center spindle. I do not remove any chocolate - I use a disposable glove as I don't want my bare fingers in the chocolate.
The washer is about 0.94" thick. The polycarbonate sheets are available at Lowes/HD. A circle cutter makes a nice 2" dia. circle.
The height of the washer prevents the roller stones from touching the bottom of the bowl. The chocolate continues to move and flow but with no grinding.
I also use a similar sous vide setup but with a hair dryer. I prefer the lower temperatures and the steady cycling. A heat gun puts out a tremendous blast of super hot air. This seems to scorch the chocolate and risks damaging the grinder.
