Shachi Engineering at PALMEX Medan 2026

As Shachi Engineering participates in PALMEX Medan 2026, one of the important conversations with oleochemical manufacturers is not simply about producing beads. It is about how the beading process should be engineered around the behavior of the product being processed.

This distinction matters.

Stearic acid, palmitic acid and hard palm stearin may all enter a beading plant in molten form, but they do not necessarily behave in the same way during cooling and solidification. Their melting characteristics, viscosity, heat released during solidification and required final product condition influence how the process should be configured.

This is where a beading plant becomes more than a piece of equipment. 

It becomes a product-specific thermal and particle-formation system.

From Molten Product to Consistent Beads

At its simplest, the process can be understood through a chain:

Melt → Droplet Formation → Cooling → Crystallization/Solidification → Bead

Every stage influences what happens next.

The molten product first needs to be converted into droplets of the required size. Those droplets then travel through a controlled cooling environment, where heat is removed and the product progressively solidifies.

The important point is that droplet formation and cooling cannot be treated independently.

A larger droplet requires a different cooling history from a smaller one. Similarly, the amount and rate of heat that must be removed depend on the physical behaviour of the product.

Therefore, achieving a consistent particle size distribution is not only a nozzle-selection exercise. It is the result of coordinating atomization, airflow, temperature, residence time and subsequent cooling as one process.

Why Cooling Architecture Matters

One of the most important engineering decisions in an oleochemical beading plant is determining where and how much cooling is required.

For products such as stearic and palmitic acid, cooling can be distributed between the primary beading chamber and a subsequent cooling stage such as an integrated or intermediate fluidized bed.

Hard palm stearin can require a different approach. Its solidification behavior and tendency toward lump formation can make additional post-cooling important. In such applications, the cooling architecture may extend from the main chamber to an integrated fluidized bed and then to an external cooling stage.

The objective is not simply to make the product cold.

The objective is to remove heat at the right stage of bead formation and stabilization so that the product leaving the system has the required physical characteristics and is suitable for subsequent handling.

This is why the cooling system should be selected from the product backwards rather than applying one standard configuration to every application.

Open Loop or Closed Loop?

Air management is another important design consideration.

Depending on the product, plant environment, required operating conditions and process economics, a beading system may operate using an open-loop or closed-loop air configuration.

The decision should consider factors such as:

• product characteristics and melting behaviour
• cooling duty
• ambient conditions
• required outlet temperature
• plant capacity
• energy consumption
• process-air requirements
• operational flexibility

The right configuration therefore comes from understanding the complete process rather than selecting an air-handling arrangement in isolation.

Advanced Beading Technology Is About Process Control

Modern beading plants increasingly depend on instrumentation and automation, but automation alone does not make a process advanced.

The real value comes from identifying the variables that influence bead formation and then controlling them consistently.

Air temperature, airflow, product temperature, feed conditions and other operating parameters interact throughout the process. A well-engineered control philosophy helps operators maintain the required operating window while responding to changes in production conditions.

Shachi's current beading systems include options such as open/closed-loop operation, fluidized-bed post-cooling, fines separation and PLC/SCADA-based process control. Shachi Engineering

The engineering objective is therefore:

Measure the right variables → understand their interaction → control the process → maintain consistent output.

One Plant, Multiple Oleochemical Products

The challenge becomes even more interesting when manufacturers want to process multiple products in the same plant.

A plant designed only around one operating point may struggle when the product changes.

For a multi-product facility, engineering needs to consider the operating window of each product and determine which process parameters need to change during product changeover.

Shachi has practical experience with this approach in Indonesia. A 5 TPH beading plant commissioned in Medan was engineered to process four fatty acids—Lauric Acid (C12), Myristic Acid (C14), Palmitic Acid (C16) and Stearic Acid (C18)—within a single system. Shachi Engineering

That illustrates an important direction for the oleochemical industry:

The future is not necessarily one plant for one product. It is intelligently engineered process flexibility.

Engineering the Beading Plant Around the Product

When evaluating a new beading plant, capacity is naturally important—but it should not be the starting and ending point of plant selection.

The engineering discussion should begin with the product itself:

What are we processing? How does it behave while cooling? What bead characteristics are required? How much heat needs to be removed? What happens when the product changes? What conditions must remain controlled to achieve repeatable production?

Once those questions are understood, decisions around atomization, cooling stages, airflow, fluidized-bed cooling, open or closed-loop operation and automation become much more meaningful.

That is the engineering philosophy Shachi Engineering is bringing to conversations at PALMEX Medan 2026.
