I have a simple question and have searched exhaustively for an answer but not found anything clear-cut.
What is the fundamental difference between different Continuous Tempering machines like FBM and Selmi machines? I see a significant price difference but am trying to see if there is any justification to that difference; relative to similar models with similar output capacities. I am scaling my business and will be purchasing one very soon. Looking for help. thanks!!

Hi. I was wondering if you could tell me what are the names of the machines that FBM built for high-viscosity chocolate. They have quite a few tempering machines and I can’t do any kind of search with regard to high-viscosity chocolate.

reply toIt’s easier for me to calculate in metric.

2.2ozs is about 62.5gr. If there are three bar cavities per mold that’s 187.5gr/mold. If you can deposit at 5 molds/minute with a mold loader that’s about 1kg/minute of tempered chocolate which means you want a machine offers a tempering throughput of at least 60kg/hr. Assuming 4 hours of productivity during a working day you’re talking 240kg in a day – many times the 100lbs every 36 hours you mention.

FBM’s Unica has a working bowl of 40kg with a tempering throughput of roughly double that. You could add a 100kg melting tank with sensor and pump and be able to handle your production needs quite handily. FBM also makes folded vertical cooling “tunnels.” The smaller of the two cools 50 molds at a time and needs only about 2 meters (6.5 feet) of linear floor space.

@DiscoverChoc I am scaling rapidly. My bars are 2.2oz and I have good polycarb molds for them. It is difficult for me to know what my quantities will look like in this scaling process. Both my DtC and Retail markets are growing independently. As it stands, I need to temper at least one 100lb batch every 36hrs as it stands without any further scaling; having not even scratched the surface of even my potential regional reach. I am preparing for that need to exponentiate quickly. My budget will be determined a lot by what equipment I need, as I am going into a round of investment talks relative to what I hone in on for my needs. I certainly do not want to waste investment capital, but am willing to pay what is necessary to make this work and make it scalable! I know this is vague but I hope it helps. Honestly maybe you have some ideas that will help me understand what that scaling potential looks like from experience.

One of the things I need to know before answering your question is how much chocolate do you want/need to temper every day? What is the weight of each bar? And … do you have a budget in mind?

@DiscoverChoc Thanks for the response. I was afraid of that answer! I make raw superfood chocolate and it tends to be thicker than most. I add substantial cacao butter to normalize it, however. As such I personally thank you for helping pave the way for more adaptability in more viscous chocolates =) I guess my main question could be as follows; is the extra price for a Selmi actually worth it when compared to the quality of an FBM? Is it worth looking at other companies? (It seems the conversation rests most strongly on these two brands, I know little of the other contenders products). Perhaps most important of all; knowing a bit more about the nature of my product, what questions should I be asking these guys? I have an open line of communication with Tomric, and will be establishing one with FBM as well. I will contact any other companies that I should be considering as well (like Gami).


All of the continuous tempering machines at this end of the market (FBM, Selmi, Gami, etc) use the same basic technical approach to tempering. Chocolate is melted in a working bowl and the melted chocolate is transported through a chilled pipe by an auger. Crystals are developed on the inside of the pipe, scraped off the sides, and mixed into the chocolate before it leaves the spout. Chocolate that is not used is detempered and retemepered in a cycle and that’s where continuous comes from – the cycle is not interrupted as it is in batch tempering approaches.

The brands differ in the engineering details and approach, manufacturing, and other aspects. It may be helpful to know that FBM introduced continuous tempering into the artisan confectionery workshop in Italy in 1977. To some extent all of the other brands copied (though not literally copy) what FBM did, with a focus on different aspects of the process.

FBM take a different approach to manufacturing – all machines are made to order, where other companies manufacture and hold finished machines in inventory. If you want a machine with a specific customization you may not be able to get it from Selmi but could get it from FBM. One example is an extended entrance section or take-off belt on the enrober.

FBM takes a different approach in engineering, building in a lot of electronic safeguards to make it harder for inexperienced operators to make simple mistakes. For example, after you turn the tempering system off on an FBM tempering machine, you cannot stop the auger until the chocolate in the pipe warms up. This is to help ensure the machine is not turned off with tempered chocolate in the pipe. This feature extends to the machine automatically reversing the auger when it’s stopped to empty the tempering pipe of chocolate.

If you are enrobing 500 pieces per hour w/ 5gr/pc you don’t need a tempering capacity of 75kg per hour as you’re only using 2.5kg/hr. With FBM you can put a 180mm (7″) enrober on a machine with a working bowl capacity of 10kg if that’s what you need.

Some machines use water for heating and cooling, others use a combination of water and chilled gas or electrical resistance wire and chilled gas. There are advantages and disadvantages to both in term of cost and complexity.

Some machines are easier to wash than others but, in truth, you should not be washing continuous tempering machines on a regular basis unless there is a very specific cross-contamination issue you are dealing with. You need to take a look at the amount of time going from dirty to completely dry, not just how long it takes to remove the auger when assessing cleaning times.

In truth what happens is that one company introduces a feature and soon thereafter it shows up on other companies’ machines. There’s a constant ebb and flow of features and functions that makes it difficult to say, absolutely, one brand is definitely better.

I work with FBM in part because they listen to my ideas for improving machines. With my help and the help of customers, FBM built the first tempering machines specifically for high-viscosity, two-ingredient, craft chocolate back in 2013. Other companies are starting to offer similar capabilities.

So it’s not a simple question. You should spend some time with each manufacturer matching your production requirements against the capabilities of specific machines to determine with is the best fit for what you want to do, and your budget. What I will say is that setting a maximum price you’re willing to pay that would mean “settling” for a machine that’s not a good fit is a bad idea.
