Rotary Biscuit Moulder vs. Biscuit Extruder: Which One is More Efficient for Industrial Production?


Biscuit manufacturing involves several crucial steps, and two popular machines used in industrial production are the rotary biscuit moulder and the biscuit extruder. These devices play a significant role in shaping perfect biscuits that are produced on a large scale. While both machines serve the same purpose, understanding the differences in their efficiency can help manufacturers make an informed decision. In this article, we will compare the rotary biscuit moulder and the biscuit extruder to determine which machine is more efficient for industrial production.

I. Rotary Biscuit Moulder

The rotary biscuit moulder is a traditional machine widely used in the biscuit industry. It consists of a rotating drum with engraved patterns that shape the dough into desired forms. The process begins by placing the dough in the hopper, which is then evenly distributed onto the rotating drum. As the drum rotates, the biscuit shapes are formed and released onto the baking tray.

A. Efficiency of the Rotary Biscuit Moulder

The rotary biscuit moulder offers high efficiency due to its continuous production process. The machine can handle large quantities of dough, making it ideal for industrial-scale operations. Its consistent and uniform shaping mechanism ensures that each biscuit retains its desired shape, leading to a high production yield. Moreover, the machine's durability and reliability contribute to its efficiency, as it requires minimal maintenance and can withstand prolonged use.

B. Limitations of the Rotary Biscuit Moulder

One limitation of the rotary biscuit moulder is its lower flexibility compared to other machines. Since the machine operates with a fixed pattern on the drum, it can produce biscuits in only a specific shape. Any change in biscuit design would require replacing the entire drum, which can be time-consuming and impractical. Additionally, the rotary biscuit moulder may not be suitable for complex biscuit designs that demand intricate details.

II. Biscuit Extruder

The biscuit extruder is another popular machine used in biscuit production. It operates on the principle of forceful extrusion, where the dough is pushed through shaped nozzles to form biscuits of various designs. The dough is fed through a hopper and is then extruded onto a conveyor belt, where it is later baked.

A. Efficiency of the Biscuit Extruder

The biscuit extruder offers notable efficiency through its versatility and wide variety of shapes it can produce. Manufacturers can easily change the shape by swapping the extrusion nozzles, providing flexibility in biscuit designs and allowing for quick adaptation to market demands. Additionally, the extrusion process ensures precise weight control and uniformity in biscuit size, contributing to its overall efficiency.

B. Limitations of the Biscuit Extruder

Despite its benefits, the biscuit extruder has limitations that affect its efficiency. The extrusion process can be slower compared to the rotary biscuit moulder, as it requires forceful push-through of dough. This can impact the production rate and reduce overall output. Moreover, due to its complex mechanism, the biscuit extruder may require more frequent maintenance to ensure proper functioning of the extrusion nozzles and conveyor belt.

III. Comparison of Efficiency

To determine which machine is more efficient, we must consider several factors, such as production rate, versatility, and maintenance requirements.

A. Production Rate

In terms of production rate, the rotary biscuit moulder tends to have an advantage. Its continuous process allows for a steady and uninterrupted production flow, making it suitable for large-scale operations. On the other hand, the biscuit extruder's speed depends on the extrusion force and may require pauses for equipment adjustments, reducing its overall production rate.

B. Versatility

The biscuit extruder surpasses the rotary biscuit moulder in terms of versatility. It can easily adapt to different biscuit designs by simply changing the extrusion nozzles. This flexibility allows manufacturers to introduce new products swiftly and meet diverse consumer demands. In comparison, the rotary biscuit moulder's fixed pattern limits its ability to produce a wide variety of biscuit shapes and designs.

C. Maintenance Requirements

Both machines have their own maintenance requirements, but the rotary biscuit moulder generally requires less attention. Its simple design and fewer moving parts minimize the risk of breakdowns, reducing downtime and increasing productivity. The biscuit extruder, on the other hand, may need more frequent maintenance due to its intricate system and the need for regular cleaning and nozzle replacements.


When determining the most efficient machine for industrial biscuit production, it is essential to evaluate specific requirements and objectives. While the rotary biscuit moulder offers high production rates and durability, the biscuit extruder shines in terms of versatility and the ability to adapt to changing market demands. Manufacturers must consider their production volume, product variety, and maintenance capabilities before making a decision. Ultimately, selecting the most appropriate machine will ensure efficient biscuit production and enhanced overall productivity.
