Cryogenic mixer for frozen fruits and vegetables
Enhance frozen food quality with rapid, uniform mixing and precise temperature regulation, ensuring consistent coatings and solidification, perfect for maintaining texture and flavor integrity.

Mixes and Coats Frozen Foods with Precision
The Cryogenic Mixer from Stolz is engineered to meet the demands of frozen food manufacturers, agribusinesses, and spice producers by delivering precision mixing and coating processes. Utilizing a unique double rotor with blades, it ensures rapid homogenization of frozen fruits and vegetables in 45 to 60 seconds, maintaining product integrity through minimal product alteration. The mixer excels in applications such as creating glazed fruit coatings and herb-crusted vegetables, with a specialized nitrogen injection system that stabilizes coatings and preserves produce. Designed for automated, high-speed batch operations, this mixer features a hygienic design that simplifies maintenance and complies with food safety standards. Integration into existing production lines is seamless, supported by automation that includes high-precision control of sauce and spice injection processes. The equipment’s energy-efficient operation and low maintenance costs are achieved through optimized mechanical and pneumatic components, complemented by the corrosion-resistant stainless steel construction. Customization options and engineering support ensure adaptability to various production needs, solidifying its role as a critical asset in frozen food and agrofood processing.
