Solid-state microwave-vacuum drying for high-meat pet food
Mildtech's patented microwave-vacuum drying system rapidly reduces moisture in high-meat pet food formulations while preserving nutrients, aroma, and texture. This energy-efficient technology offers a scalable solution for commercial production, reducing drying time and costs.
Overview
Mildtech has developed an innovative solid-state microwave-vacuum drying system specifically designed for high-meat pet food products. This cutting-edge technology significantly reduces moisture content from approximately 60% to less than 10% (Aw < 0.65) within 40-60 minutes. The process operates at low temperatures, preserving essential nutrients, aroma, texture, and color far more effectively than traditional hot-air or freeze drying methods. Additionally, it uses 60-80% less energy compared to conventional drying techniques. The technology has been successfully validated with various high-moisture ingredients, demonstrating its potential to enhance product quality and support sustainability in pet food production.
