Petroncini MCR 1000

• Grinding roasted coffee beans to various consistencies for espresso, filter, or instant coffee production.
• Milling cocoa nibs into cocoa liquor for chocolate manufacturing.
• Processing nuts and seeds into pastes or flours for confectionery and food ingredients.
• Reducing spices to fine powders for culinary and industrial applications.
• Milling grains like wheat or maize for flour production in smaller-scale operations.

Typical throughput

For this class of industrial roller mill, throughput can typically range from 500 kg/h to 1500 kg/h, depending on the desired grind size and product density. Buyers should confirm exact capacity with the seller.

Roller configuration

Petroncini MCR series mills commonly feature multiple sets of chilled cast iron rollers, typically two or three pairs, for progressive grinding. The unit includes two spare rollers.

Power supply

Industrial roller mills of this size commonly require a three-phase electrical supply, typically 400V, 50Hz, with a motor power ranging from 15 kW to 30 kW. Specific requirements should be confirmed with the seller.

Cooling system

Units like the MCR 1000 often incorporate a cooling system to manage heat generated during grinding, which is crucial for preserving product quality, especially for coffee and cocoa. This unit is stated to include a cooling system.

Footprint

For a machine of this capacity, a typical footprint might be around 1.5m x 1.5m x 2.0m (LWH), though exact dimensions will vary. Buyers should request precise measurements from the seller.

Suitable feed size

These mills are designed to process pre-broken or whole roasted beans, nibs, or similar granular materials. The feed size should be appropriate for the mill's intake mechanism.

Maintenance requirements

Regular maintenance for roller mills includes roller re-sharpening or replacement, bearing checks, and cleaning. The inclusion of re-sharpened spare rollers indicates good prior maintenance.

• What is a roller mill grinder primarily used for?

  A roller mill grinder, such as the Petroncini MCR 1000, is primarily used for precision grinding of friable materials like roasted coffee beans, cocoa nibs, or spices, achieving consistent particle sizes through compression and shear.

• What does 'refurbished in 2020' imply for this unit?

• Why is a cooling system important on a roller mill?

• What are the benefits of having spare rollers?

• Can this machine produce different grind sizes?

• What kind of manual is typically included with such equipment?

Food processing mills are valued for consistent particle size reduction across grain, spice and dry ingredient applications. Buyers typically prioritise motor condition, grinding chamber cleanliness and wear on grinding elements when purchasing used equipment. Industry sentiment highlights reliability and longevity as key strengths, particularly with well-maintained units. Attention should be given to throughput capacity matching production needs and compatibility with existing systems. Corrosion resistance matters for hygiene-sensitive environments. Reputable machines from established manufacturers generally command buyer confidence in the secondary market.
