Molasses is a cost effective feed ingredient widely used in modern feed production. It is not only an energy source, but also offers several functional benefits.

Molasses helps improve digestibility, enhance palatability, reduce dust, and improve pellet quality. Because of these advantages, more feed mills are adopting molasses in their production processes.

However, due to its special physical properties, molasses application also brings several technical challenges.

Molasses is a viscous liquid with good flowability under normal temperatures. Even at low temperatures around minus 20 degrees Celsius, it can still be stored and used without major issues.

Standard storage tanks can be used, but due to its sugar and moisture content, molasses can be corrosive. Therefore, stainless steel tanks are recommended.

To handle extreme conditions, heating coils can be installed at the tank outlet to maintain flowability.

Molasses also contains impurities, and due to its viscosity, filtration can be difficult. It is recommended to install filters in the pipeline with sufficient surface area. Regular cleaning is necessary to prevent blockage.

For conveying, gear pumps are commonly used, but they have a shorter lifespan due to wear on seals and gears. For large scale applications, pneumatic diaphragm pumps are more stable and reliable.

Molasses can be added into feed production through several methods, depending on production requirements.

This is the earliest and simplest method, similar to oil addition.

It requires minimal modification to existing equipment and is suitable for most products. However, due to the low mixing speed, it is only suitable for low inclusion levels, typically below 3 percent.

Disadvantages include poor mixing uniformity, high residue inside the mixer, frequent cleaning, and increased wear on conveyors and elevators.

Molasses can be added into the conditioner together with steam. With high speed mixing, the liquid can be distributed more evenly.

This method is suitable for pellet production. In practice, stable operation is usually achieved at around 2 to 5 percent inclusion, depending on formulation and moisture control.

Higher inclusion levels may affect pellet stability and require careful adjustment of conditioning parameters.

A molasses mixer is a dedicated solution designed for liquid addition.

It is a continuous mixing system that improves mixing efficiency and reduces residue. Compared with adding molasses in a standard mixer, this method provides better control and allows higher inclusion levels.

In practical applications, around 4 percent addition is commonly used for stable production.

Different paddle designs affect performance. Larger paddles improve mixing uniformity but increase residue. Smaller paddles improve efficiency but may reduce mixing quality.

The BOA system combines conditioning and compression.

Molasses is added during conditioning, and then the material is compressed under high temperature and pressure. This improves the integration between molasses and raw materials and enhances pellet quality.

This method is commonly used in ruminant feed production.

Post spraying is widely used for oil addition and is also being applied to molasses.

Molasses is sprayed onto finished pellets after pelleting, followed by mixing before packaging.

This method is suitable for low inclusion levels and reduces the impact on the main production line. However, it requires high system stability and good molasses quality.

Based on practical experience, the main challenge of molasses is not only its viscosity, but its slow absorption by feed materials.

The goal of different systems such as molasses mixers or BOA systems is not just to improve spraying uniformity, but to increase the contact and absorption between molasses and materials.

This improves overall mixing quality and production stability.

When optimizing molasses application, focusing on absorption efficiency can bring better results than only improving spraying methods.
