Moroccan maize (corn) milling market

 Moroccan maize (corn) milling market

For the Moroccan maize (corn) milling market, there is no single mandatory national mesh standard equivalent to wheat flour regulations. Most mills supply products according to customer requirements (couscous manufacturers, bakeries, snack manufacturers, etc.). However, based on Moroccan commercial practice, North African semolina specifications, and industrial dry-maize milling standards, the following particle sizes are commonly used.

Recommended milling specification for Morocco

1. Coarse Corn Semolina (Semoule Grosse de Maïs)

• Particle size: 700–1000 µm preferred

• Equivalent mesh:

• 18 mesh ≈ 1000 µm

• 20 mesh ≈ 850 µm

• 25 mesh ≈ 710 µm

• 30 mesh ≈ 600 µm

Typical distribution:

• 90% between 700–1000 µm

• Less than 10% below 600 µm

This grade is similar to coarse semolina used throughout North Africa for couscous and traditional foods.

2. Fine Corn Semolina (Semoule Fine de Maïs)

Recommended size:

• 300–600 µm

Equivalent mesh:

• 30 mesh ≈ 600 µm

• 35 mesh ≈ 500 µm

• 40 mesh ≈ 425 µm

• 50 mesh ≈ 300 µm

Typical distribution:

• 90% between 300–600 µm

Common uses:

• Fine couscous

• Breakfast cereals

• Extruded snacks

• Instant maize products

This range also aligns well with industrial maize meal classifications.

3. Bedes Flour (Farine Bedès / Bédès)

"Bedes" flour in the Moroccan market generally refers to a very finely milled maize flour, finer than semolina.

Recommended particle size:

• 150–300 µm

Equivalent mesh:

• 50 mesh ≈ 300 µm

• 60 mesh ≈ 250 µm

• 70 mesh ≈ 212 µm

• 100 mesh ≈ 150 µm

Typical specification:

• 90% passing 60 mesh

• Majority retained on 100 mesh

Uses:

• Bread blends

• Cakes

• Pastry

• Baby food

• Batter mixes

Industrial maize flour is typically classified below approximately 212 µm, with finer commercial bakery grades extending up to about 300 µm.

Recommended sieve configuration for your maize mill

If you are designing a Moroccan maize milling plant, I recommend producing these three commercial products:

This product range matches the particle sizes commonly demanded by Moroccan food processors and retailers.

If your company (www.immyhitech.com) is designing a maize milling line for Morocco (5–200 TPD or larger), I can also prepare:

1. A complete flow sheet for producing these three grades.

2. A plansifter/sieve cloth specification (mesh numbers for each plansifter section).

3. A roller mill gap setting table for each break and reduction passage to consistently achieve the required Moroccan granulometry.
