Marel - 2020 MAREL Smart Line grader

• Accurate portioning and grading of fresh or frozen food products by weight.
• Sorting products into different weight categories for packaging or further processing.
• Integration into automated processing lines for improved efficiency and yield.
• Quality control and consistency in food production, particularly for meat, poultry, and fish.
• Labelling individual portions or batches based on weight and other parameters.

Typical throughput

For this class of equipment, throughput can vary significantly based on product size and desired accuracy, commonly ranging from 60 to over 200 pieces per minute.

Weighing accuracy

Units of this type typically offer high precision, often within +/- 1-2g for a standard deviation, depending on the product and speed.

Product weight range

Graders like the Smart Line are commonly designed to handle individual product weights from approximately 50g up to several kilograms, with specific ranges configured to the application.

Construction material

Equipment for food processing is typically constructed from AISI 304 or 316 stainless steel for hygiene and durability, with food-grade plastics (PE, POM) for contact parts.

Power supply

Units commonly operate on standard industrial three-phase power, typically 400V, 50Hz, with specific power consumption dependent on configuration.

Ingress protection (IP) rating

For washdown environments, an IP65 or higher rating is common, with some critical components achieving IP69K for high-pressure, high-temperature cleaning.

Footprint

The overall length of a grading line can vary significantly based on the number of outfeeds and additional modules, typically ranging from 3 metres for basic units to over 10 metres for complex systems.

• What types of products can this grader handle?

  This type of grader is typically used for fresh or frozen individual food items such as poultry, fish fillets, meat portions, and certain fruits or vegetables, within its specified weight and size limits.

• Is this unit suitable for integration into an existing processing line?

• What maintenance is typically required for a grader of this type?

• Can the grading parameters be easily adjusted?

• Does this equipment come with software for data analysis?

Sorting and grading equipment is valued for improving product consistency and processing efficiency. Buyers typically seek machines in good mechanical condition with minimal wear on critical components like belts, motors and calibration systems. Common strengths include reliable performance when properly maintained, cost savings versus new equipment, and compatibility with existing production lines. Industry sentiment favours models from established manufacturers known for durability. Buyers should inspect electrical systems thoroughly and verify spare parts availability before purchasing used units.
