More and more customers demand different types of biscuits, and maintaining consistent quality of biscuits has become a necessity. To meet these changing demands, your biscuit business can make a difference by understanding the manufacturing insights for both soft and hard biscuits.
Both types of biscuits demand different equipment, dough handling methods, baking conditions, and quality control methods. Manufacturers who aim at maximizing throughput, waste reduction, and producing products of consistent quality need to understand these differences. The use of contemporary solutions like the soft biscuit production line or the hard biscuit production line enables the factories to be capable of scaling productively while ensuring that the market demands are strictly adhered to.
This blog examines some of the major manufacturing best practices to help biscuit makers increase their productivity.
Why the Difference Between Soft vs Hard Biscuits Matters
The major challenge biscuit manufacturers have to overcome is that they have to be productive and, at the same time, preserve the product integrity. The demand for biscuit production lines is growing at a rate of 5.2% from 2026 to 2033. This makes manufacturers focus more on their production lines. Soft cookies, shaped snacks, and filled cookies need soft handling of dough to preserve the aeration. Hard biscuits such as crackers, Marie, or glucose biscuits need to be formed, rolled, and cut into sheets with great precision to make them crisp.
These differences have an impact on:
- Dough preparation
- Techniques of forming and shaping
- Moisture management
- Baking profiles
- Cooling and packaging methods.
A well-planned hard biscuit production line or even a soft biscuit production line keeps these factors in consideration and provides idealized mechanical motions to maintain quality at industrial speed.
The Science of Biscuit Dough: Soft vs Hard
Soft Dough: High Fat, High Sugar, Low Gluten Development
- High fat and sugar content are normally a feature of soft dough, which does not encourage gluten formation and makes the dough sticky.
- The delicateness of this is due to the fact that rotary molding systems are desirable, since they shape the biscuits without overworking the dough.
- The rotary-molding modules, which are common in the advanced soft dough production systems, are used in most industrial plants, like New Era’s soft biscuit production line, to make the biscuits retain their aerated texture and fine details of shape.
Hard Dough: Strong Gluten Network for Crispness
- Hard dough has a completely different behavior. It is more water absorptive, has a better gluten structure, and is more elastic and thus is suited to sheet forming and cutting off.
- Hard biscuits have a well-developed gluten structure, which provides them with crispness.
- In order to attain elasticity and dough strength, manufacturers use sheeting and cutting systems.
- Thickness control, consistent shaping, and uniformity of large batches are all possible with the hard biscuits rotary cutters systems.
Soft Biscuit Production Line: Engineering for Delicate Dough
Soft dough manufacturing demands machinery that is capable of preserving the structure of the dough and producing uniform shapes at high rates. A typical soft biscuit production line includes:
a. Precision Mixing & Dough Conditioning
This is done by first mixing with extreme accuracy and precise dough conditioning, in which the temperature and texture are maintained constant to avoid early melting of fats.
b. Rotary Molding for Complex Shapes
When the dough has the best plasticity, rotary molding machines are used to shape each segment in a gentle manner, thereby creating finer patterns and/or correct weight distribution without affecting the composition of the dough. Soft biscuit production lines, like those used to manufacture short-dough cookies, show how sophisticated molding cavities ensure uniformity of the product even in cases requiring inclusions or intricate designs.
c. Controlled Baking Profiles
The baking of soft biscuits requires the cycles are shorter, and higher temperature zoning to avoid coloration variation and moisture loss.
d. Spiral or Wire-Mesh Cooling Conveyors
After baking, the biscuits are transported to the spiral or wire-mesh cooling conveyors, where the flow of the air cools down the biscuits. This gradual cooling is necessary, as soft biscuits are fragile compared to their hard counterparts, and any abrupt handling or rapid cooling is a threat to breaking the product and the loss of the product as well.
Hard Biscuit Production Line: Built for Precision and High Output
Production of hard biscuits requires the precision of mechanical processes and robust development of doughs. A hard biscuit production line generally includes.
a. Intensive Mixing and Dough Resting
Water absorption as well as gluten development have to be uniform. The mixture of dough is followed by a resting period, which enhances sheetability and gives even gluten relaxation.
b. Sheeting and Laminating
Dough is then passed through sheeting and laminating machines, where the dough is rolled into various layers. Lamination is important to the formation of an airy, flaky, crispy texture that is common in crackers and crisp biscuits.
c. Rotary Cutting for Defined Edges
After the formation of the laminate, the biscuits are stamped to shape with clean edges and the same thickness using rotary cutters. Rotary cutting systems with similar designs are also common in industrial plants, such as hard dough biscuit lines with high capacity, with servo-controlled sheeters and automated scrap-return systems to provide a continuous production process.
d. Tunnel Oven with Multi-Zone Baking
Hard biscuits are usually baked in long, multi-zone tunnel ovens. These ovens slowly dry out moisture so as to attain the crispness and retain the same color and texture.
e. Cooling Conveyors with Adequate Airflow
The biscuits after baking are then loaded into longer cooling conveyors, wherein the airflow and the conveyor speed are used to stabilize the product and then packaged.
Key Differences in Production Processes| Parameter | Soft Biscuits | Hard Biscuits |
|---|---|---|
| Dough Type | High-fat, soft dough | Low-fat, elastic dough |
| Forming | Rotary molding | Sheeting + laminating + rotary cutting |
| Baking Time | Shorter | Longer |
| Texture Goal | Soft, crumbly | Crisp, brittle |
| Moisture Content | Higher | Lower |
| Automation Needs | Gentle handling | Precision and robustness |
These differences directly influence machinery design, operator handling, and automation strategies.
Impact on Productivity: What Manufacturers Must Consider
In a biscuit factory, productivity is determined by the synchronisation of the dough handling, forming, baking, and cooling. Both soft and hard biscuits have to be approached differently.
a. Throughput Optimization
Hard biscuits typically allow higher line speeds due to a stronger dough structure. Soft biscuits, however, require controlled speeds to prevent shape distortion. Hard biscuits generally permit a greater line speed because of superior dough structure. Soft biscuits, on the other hand, need to be controlled at low speeds in order to avoid distortion of shape.
b. Energy Efficiency
Tunnel ovens require the highest amount of energy. There is optimization of the temperature zoning to enhance the quality of the product and the cost. Heat recovery automated ovens are becoming popular.
c. Waste Reduction
The minimization of waste is accomplished by the use of sophisticated dough-handling systems that minimize deformation in soft dough and scrap in hard dough. This makes the production flow smoother, reduces the use of materials, and makes the overall line performance efficient.
d. Quality Consistency
Constant quality is enhanced with real-time monitoring devices used in measuring moisture, weight, and visual correctness.
This makes the biscuits consistent in texture, appearance, and product across all of the batches.
How Choosing the Right Production Line Improves Profitability
1. Higher Output Without Compromising Quality
It is possible to achieve higher production without affecting the quality, in case the machinery is designed to suit the precise properties of the dough. When the equipment reflects the level of moisture, the level of elasticity, and the processing behaviour of the dough, it will do away with unnecessary strain on the line and increase the possibility of a lack of consistency. Consequently, the number of bottlenecks reduces significantly, and factories are able to sustain large volumes of production as well as produce at high quality standards.
2. Reduced Downtime Through Smart Systems
Automation also promotes efficiency in operations by minimizing downtime. Provided with automatic dough feed controllers. This not only accelerates changeovers but also reduces the possibility of human error, thus allowing continuous and stable production.
3. Better Resource Utilization
Another opportunity is the improved use of resources. Control of costs by manufacturers is better because of technologies that would provide a perfect handling of dough, minimum scrap, and maximum baking cycles. Uninterrupted uniformity in terms of thickness ensures there is no waste of material, and the whole process becomes cost-effective through proper portions.
4. Scalability for Future Growth
Modular systems are easy to scale to meet the demands of future growth. The factories are able to add capacity, or they can upgrade parts of the factory without necessarily incurring the expenses of an all-new production line, which is beneficial to long-term expansion plans.
5. Enhanced Food Safety Compliance
Hygienic design, contact surfaces made out of stainless steel, and dust-free systems, facilitate food safety compliance and bring the manufacturers into compliance with the standards globally.
