Bartletts

• Used for homogeneous blending of various tea leaf grades and types to create consistent tea blends.
• Suitable for mixing dry granular or leafy products where gentle tumbling action is required.
• Can be adapted for blending other dry food ingredients, herbs, or spices.
• Often found in tea packing plants, food processing facilities, and ingredient preparation areas.

Typical capacity

For this class of equipment, capacities commonly range from 50 kg to 200 kg per batch, depending on the specific drum volume.

Power supply

Units of this type typically operate on a 3-phase industrial electrical supply, commonly 400V, 50Hz in the UK.

Construction material

Blending drums are typically constructed from mild steel or stainless steel, with stainless steel being preferred for food contact applications.

Mixing principle

Utilises a gentle tumbling and cascading action within a rotating drum to achieve blend homogeneity.

Footprint

The footprint for a drum mixer of this capacity class can vary, but typically requires several square metres of floor space, including access for loading and unloading.

Maintenance requirements

Generally low maintenance, primarily involving regular cleaning, lubrication of bearings, and inspection of drive components.
