Shaffer’s new, patented VerTech Refrigeration Jacket offers bakeries peak performance and efficiency, with the most effective, durable and energy efficient bowl cooling available. The VerTech Jacket is specifically for triple roller bar mixers that demand mixing durability; easily holding up to stiff doughs and high horse power machines.
The VerTech Refrigeration Jacket comes standard on all Shaffer Triple Roller Bar Mixers. For additional dough cooling needs we offer:
Refrigerated agitator cooling††
Breaker bar cooling
Shaffer mixers are available in enclosed frame, open frame and hybrid frame* designs.
New design is engineered to distribute dough force over a larger area and results in 75% reduction of stress on channel material and 63% reduction of stress on weld joints.
The refrigeration jacket is manufactured in discrete steps with three definitive inspection points for maximum quality control.
New design provides same heat transfer with up to 46% reduction in pressure drop over corrugated jacket with turbulence pins, resulting in less energy to operate the glycol system.
In accelerated fatigue testing on a full scale model, using over twice the force of a low absorption dough, the VerTech Jacket lasted over 40X longer than other conventional jackets.
Finite Element Analysis and Full Scale
Accelerated Fatigue Testing:
- 75% Reduced stress on refrigeration channels
- 63% Reduced stress on weld joints
*Hybrid frame design is a winner of the BEST in Baking Award IBIE 2013
**Compared with corrugated jacket with turbulence pins
- 46% Reduced glycol system pressure drop**
- 40x Increased life of jacket
