Description:

The Littleford VT-4000 Vacuum Plow Mixer/Dryer is a high-performance mixing and drying solution designed for high-efficiency blending, drying, and reaction processing of powders, granules, and pastes. Constructed from 304 stainless steel, this unit is built for durability, corrosion resistance, and sanitary processing.

This mixer features a 4000-liter (approx. 1057-gallon) capacity, with a 54" diameter and 121" straight side. The internal chamber is rated for 15 PSI/vacuum at 250°F, while the stainless steel jacket is rated for 75 PSI at 250°F, allowing for precise thermal processing.

Equipped with a 6" diameter shaft, 8 bolt-on plow blades, and 2 end scrapers, the mixer provides intense material movement and uniform blending. The design also includes a provision for 4 choppers, allowing for additional particle size reduction and high-speed shear mixing. The air-purged main seals ensure long-term performance with minimal contamination risk.

Powered by a 50 HP motor through a gearbox, the mixer operates with high torque efficiency. It includes various top openings for ingredient feeding, monitoring, and process integration. The 6" diameter off-center bottom outlet ensures efficient discharge of materials.

This unit is mounted on a carbon steel frame for structural stability and support. A Variable Frequency Drive (VFD) control panel is included, allowing for adjustable speed control and process optimization.
