Electric-Heating & PLC Control Tilting Kneader for Protein Bars

Karvil Machinery delivered a custom 300L tilting kneader to a Bulgarian protein bar manufacturer for pilot-scale production of high protein snack bars. This machine features electric heating for precise temperature control, PLC/HMI automation for recipe recall and real-time monitoring and an integrated dust-removal station to capture airborne powder and maintain a clean work environment 

Technical Specifications Overview

Capacity & Construction

Working Volume: 210 L (300 L full volume) in SUS 304, mirror-polished stainless steel for food-grade hygiene 

Contact Material: All contact parts in SS 304, easy to CIP and resistant to corrosion 

Mixing Elements & Discharge

Z Blades: Dual counter-rotating Z-shaped blades deliver high-shear kneading for homogeneous dispersion of powders and pastes 

Hydraulic Tilting Discharge: Smooth, power-assisted cylinder tilts the mixing chamber for complete product emptying—no manual handling required 

Heating & Control

Electric Heating Jacket: Integrated electric-heating coils ensure rapid, uniform heat transfer up to specified temperatures
