Thanks, for the breaking down.

It’s truly appreciated.

Thanks for breaking down.

[EROMOSELE OTOIDE]

YES, it does.

Pre-grinding systems are generally more efficient in terms of grinding losses and energy efficiency, as they reduce the load on the primary grinding mill

The quickest and most effective way to dehull soybeans depends on your scale:

| Scale | Quickest Method | Principle |

|—|—|—|

| Small Batch (Home/Lab) | Food Processor & Water | Abrasion and Flotation |

| Large Scale (Commercial/Feed) | Hot Dehulling/Cracking and Aspiration | Thermal Shock and Air Separation |

1. Small Batch/Kitchen Method (Quickest Manual Way)

This method takes minutes (after an initial short soak) and is highly effective for preparing small quantities of soybeans for cooking or making soymilk/tempeh.

* Short Soak (Conditioning): Soak the dry soybeans in hot water (\mathbf{140^\circ \text{F}} to \mathbf{160^\circ \text{F}} or 60^\circ \text{C} to 70^\circ \text{C}) for 5 to 15 minutes. The heat and moisture loosen the bond between the hull and the kernel.

* Rupture/Cracking: Drain the hot water. Place the beans in a food processor or strong blender and add enough cool water to cover them. Use the dough blade (blunt edge) or pulse the regular blade in short, quick bursts (5 to 10 pulses). This will cause the beans to crack and the hulls to separate.

* Flotation/Separation: Transfer the cracked beans and water to a large bowl. The hulls are lighter than the kernels. Swirl the water vigorously, allow the kernels to settle for a moment, and then pour off the floating hulls and water into a fine-mesh strainer.

* Repeat: Repeat the swirling and draining process 3-5 times until most of the floating hulls are gone.

2. Large Scale/Feed Mill Method (Industrial Speed)

In a commercial setting, speed and efficiency rely on machinery that utilizes thermal and mechanical processes. This is the fastest way to get dehulled soybean meal (high-protein meal).

* Thermal Shock (Drying & Conditioning): Dry heat is applied to the soybeans (sometimes combined with a sudden cooling). This process, known as hot dehulling, makes the hull brittle and causes it to shrink away from the inner kernel (cotyledon).

* Cracking: The conditioned soybeans are immediately passed through a roller mill (cracker rolls) that cracks the whole bean into 4–6 pieces without crushing the hull too finely. This mechanically separates the hull from the kernel.

* Aspiration: The cracked mixture is dropped into a chamber where a strong stream of air (aspiration) is used to quickly and selectively suck up the lighter soybean hulls while the heavier kernels drop down to be processed further.The quickest and most effective way to dehull soybeans depends on your scale:

The crude protein (CP) percentage in whole, dry soybeans typically ranges from 38% to 42% on a dry matter basis.

Thanks for highlighting the key points.

[EROMOSELE OTOIDE]

Please, expanciate more on this.

The main raw materials used in feed milling are diverse and are primarily grouped by the key nutrients they provide: Energy, Protein, and Micronutrients.

1. Energy Sources (Carbohydrates and Fats)

These form the largest portion of the feed formula, providing the calories necessary for animal maintenance, growth, and production (e.g., milk, eggs).

[Bello Bashir]

Good question

[Muddasar]

Ensure proper ventilation, cool clean water, and reduce stocking density. Add electrolytes, vitamin C, and B-complex in water, adjust feeding to cooler hours, and maintain dry litter for comfort and reduced stress.

[Muddasar]

60-70%

[Bello Bashir]

How do we ensure safety in feedmill

[Bello Bashir]

Inconsistent pelleting: Feed mills often struggle with inconsistent pellet quality due to variations in feed formulation, improper particle reduction, or poor die and roller maintenance or setup, and ineffective hot conditioning

Which litter material gives you the best results — rice husk, sawdust, or wood shavings?
