Hello! I've recently bought a Premier Tilt Melanger and used it for the first time last night. As stated in the CA videos, I put the drum lid after the third hour to avoid water drops. Everything went well until around fifth hour when it began to make a loud high-pitched whistle-like noise. I stopped the machine immediately and found some moisture traces over the drum wall, even though the lid was totally dry.
To add a few more details:
1.-I worked with about two pounds of ingredients. 2.-As I mentioned, the sound was high-pitched, like a whistle. It's intensity was variable. At some times it just stopped, but started again a few seconds after. 3.-The rocks temperature was around 45-50C. 4.-The final chocolate didn't have lumps or fudge, but had a few bubbles here and there. It was quite smooth, but I’m not sure if it was as smooth as it should get since it was my first time running the machine.
Unfortunately I didn't take a video nor pictures of the problem. Maybe you can give me some suggestions about a proper way of doing the process. What are the chances the noise was due to water having contact with the chocolate? Should I cover the drum or just leave it without the lid? Or maybe six hours were enough to refine two pounds of ingredients and the noise was some kind of signal that it was already refined??
Thank you in advance.

Hello. As long as the chocolate remained nice and fluid, I don't think the moisture was the problem. That being said, moisture condensing on the walls of the grinder isn't good, so maybe run it longer with the lid off. I don't think it's a signal that your chocolate is refined. That would be very annoying if you wanted to run the grinder longer to do some conching and had to listen to that noise the whole time. I'm not sure what would cause a whistle noise, but I'd open it up and take a look at the belt. It may be that it needs to be tightened. -Ben

Thank you very much for your response ! Next time I'll open the machine to be sure everything is in place before running it.

You're welcome. Does the noise occur when you just run the machine with the bowl off?

Mine can be noisy as well. Does it change pitch or stop when you change speeds?

Today I ran the machine without the bowl for the same six hours I did the first time. Everything went fine. There were no high-pitched noises nor sound variations of any kind. I got curious about the bowl though and had a look at it. I noticed there was a mark at the bottom, two centimeters above the stone. There's a high chance the blades (or one of them if the whole piece was inclined) were grazing the drum. I think I'll make my second batch some day next week. I'll put special care in fitting the white lock properly, assuring a right position (I'm using a folding work table), and avoiding moisture just in case. Thank you very much for your suggestions. If the problem persists I'll record a video in case other users were in the same situation. bmikiten, what do you mean by change speeds? Premiere tilt has speed control?

Hello again! In order to keep a little precedent on the issue and help other people whenever they encounter with it, here I'll write what the solution was. Some days ago I ran my second batch. Unfortunately, it stopped again. The weird thing was this time it didn't last so long for the problem to arose. The first high pitched noise was emitted passed the first hour. It remained quiet for the next couple of hours until the sounds begun again more intense and frequent. Suddenly, the wheel stopped drive.google.com/file/d/1RSW3ViEBdu2vkGhqNTv1MrF1kofd_b3u/viewI contacted Diamond, and Bhavani answered me very quickly and nicely. He told me there must have been some cocoa powder stuck in the wheel. The solution to that problem was to disassemble the wheel and clean it with soap and water and then dry it with a hairdryer or a heat gun. Another user described the same problem in this thread chocolatetalk.proboards.com/thread/1674/premier-grinder-wheel-stops-turning. Even though it is true there was some chocolate stuck in them we found hard to believe so many had accumulated the first time we ran it. While cleaning the wheels we noticed there was something else going on. After removing the nuts, the first wheel came out easily with no problem at all. However, we weren't able to take out the one that stopped. We tried to heat it up in case there was some chocolate to melt, but didn't work; we cleaned it with hot water and soap and nothing changed. The problem was the stone wheel was out of its position over the white plastic piece. My dad solved it while I was out, and he didn't take any pictures. Only imagine a little interstice between both parts. Some hits with a rubber hammer returned it to the meant position. Happy ending: the Premier Tilt worked like charm and we enjoyed lots of delicious chocolate.
