The exact equipment depends on the biscuit recipe and shape. A simple biscuit may require mixing, forming, baking, cooling, and packaging equipment, while a more complex product can require additional systems for depositing, laminating, sandwiching, cream filling, decoration, or inspection.

The Ministry of Food Processing Industries identifies mixing and kneading, moulding, baking, cooling, packaging, and testing as important stages in biscuit production. Its sector assessment also identifies mixers, biscuit moulding machines, ovens, cooling conveyors, packaging machines, and texture analysers as corresponding equipment.

How Biscuit Production Works

A typical biscuit production line follows a sequence in which ingredients gradually become a finished packaged product.

• Ingredient preparation: Flour, sugar, fats, leavening agents, flavoring ingredients, and other recipe components are measured and prepared.

• Mixing: Ingredients are combined to produce dough with the required characteristics.

• Dough forming: The dough is rolled, laminated, deposited, or otherwise shaped according to the biscuit type.

• Cutting or moulding: Dough is divided into individual biscuit shapes.

• Baking: Formed dough passes through an oven where heat develops its structure, texture, color, and flavor.

• Cooling: Baked biscuits travel through cooling conveyors until they reach a suitable temperature for handling and packaging.

• Inspection: Samples or products may be checked for dimensions, weight, appearance, texture, or other quality characteristics.

• Packaging: Cooled biscuits are arranged and enclosed in suitable packaging.

The sequence can change according to the product. For example, cream-filled sandwich biscuits require additional filling and assembly stages.

Main Types of Biscuit Manufacturing Machines

Flour handling and sifting machines remove unwanted particles and help prepare flour for controlled processing.

Ingredient weighing systems measure recipe components according to predetermined quantities.

Dough mixers combine flour, fats, sugar, liquids, leavening agents, and other ingredients into a consistent dough.

Dough sheeters flatten dough into a controlled thickness. They are commonly associated with biscuits made from sheeted dough.

Laminators create layered dough structures by combining and folding dough sheets.

Rotary moulding machines shape suitable dough into individual biscuits using a patterned moulding roller.

Wire-cut machines produce pieces by extruding dough and cutting it into individual portions.

Biscuit ovens apply controlled heat as biscuits travel through the baking chamber.

Cooling conveyors transport baked biscuits while allowing heat to dissipate before further handling.

Packaging machines arrange and wrap or otherwise enclose biscuits according to the selected package format.

Importance

Consistent Dough Preparation

Dough characteristics influence the shape, texture, appearance, and baking behavior of biscuits. Mixing equipment helps combine ingredients according to the production recipe.

The mixing time, mixing speed, ingredient sequence, and dough temperature can influence the resulting dough. These parameters vary according to the formulation and biscuit type.

Accurate Biscuit Forming

The forming stage determines the size and shape of individual biscuits. Equipment such as rotary moulders, wire-cut machines, sheeters, laminators, and depositors can be selected according to the dough characteristics.

Consistent forming helps create biscuits with similar dimensions before they enter the oven.

Controlled Baking

Baking is one of the most important stages because heat changes the dough into a finished biscuit. The process influences moisture, texture, color, structure, and flavor.

Industrial ovens can contain multiple heating zones. Operators can control selected conditions so that biscuits receive the required thermal treatment as they travel through the oven.

Controlled Cooling

Freshly baked biscuits remain hot and can be relatively delicate immediately after leaving the oven. Cooling conveyors provide a controlled path for reducing their temperature before handling and packaging.

Adequate cooling also helps prevent unwanted moisture conditions inside packaging.

Packaging Protection

Biscuits can lose their desired texture when exposed to moisture. Packaging therefore plays an important role in protecting the product during handling and storage.

Packaging machines can arrange biscuits, form packages, apply wrapping material, and seal packages according to the selected format.
