FAQ

Is this mixer suitable for highly sticky food materials like chewing gum?

Yes, absolutely. This specific model is tailored for food-grade, highly viscous applications. All contact parts are made of SS304 stainless steel with a high-level mirror polish, which significantly reduces material adhesion. The powerful 1.5KW Siemens motor and the precise 3mm clearance between the blades and the wall ensure uniform kneading even for tough materials like chewing gum, bubble gum, or dough.

How does the heating system work?

How easy is it to discharge the material and clean the machine?

Is this machine safe for laboratory use?

The specifications state 380V, 50Hz, 3-Phase. Can you customize the voltage for my country?
