Biscuit Production Process: An Industry Overview

Biscuits are one of the most popular snacks consumed in the country. On average, nearly every third person in India enjoys biscuits with tea daily. This has helped the biscuit business to boom more than ever before in history. Most biscuits today are manufactured with the help of automated machines. Here is an industry overview for you if you are interested in learning more about how these tasty treats are produced. Let’s go through the process on a step-by-step basis.

Preparing the Dough

The type of dough depends on the biscuit being made, and each brand uses its own recipe. Some use plain flour, while others employ multigrain flour with several dried fruits. The most important factors at this stage are the consistency and temperature of the dough. Most companies use a basic dough mixer for this as it can work up the dough automatically. Some of these mixers come with inbuilt thermal sensors and priming arms that ensure each batch comes out just right. There are spiral, horizontal, and vertical type mixers in the market, and each has its own benefit for a specific type of biscuit.

Fermentation

After the dough has been mixed, it needs to be mixed with yeast. Some brands do this while preparing the dough, while others wait until the dough has been prepared. The fermentation can take anywhere from 21 to 26 hours, allowing the dough to get airy. In most cases, this is a manual process.

Shaping the Biscuit

After fermentation, the dough is sent to the shaping machine. These machines have three major parts – the roller, cutter, and laminator. The dough is first passed through the rollers to get flattened out, which allows for easy cutting. Since the process is automated, the thickness of each cookie remains constant. The sheets are then hardened with the laminator, and some toppings can be applied here. After this has been completed, the laminated sheets pass through the cutter, which precisely cuts the dough into the required shape.

Baking

Once the biscuits have been appropriately shaped, they are transferred to a massive oven. This is usually done via a conveyer belt but can also be a manual process. The oven is automated via a microcontroller, ensuring that the temperature is precise and constant for each batch. The oven also has a conveyor belt that transports the cookies away once the baking process is completed.

Packaging

Once the biscuits have completely cooled down, they are ready to be packaged. The conveyor passes them through the packaging machine, which packs them inconsistent sets. These can then be shipped in large crates and delivered to retail stores for sale.

The manufacturing process may sound a little simple at first glance; however, the most important part here are the machines used. These precise tools allow consistency in every batch to help make a biscuit brand well known. Hopefully, this answers all your questions about the biscuit production process.

FAQ of An Overview of the Biscuit Manufacturing Process

Biscuits are made mainly from wheat flour, sugar, fats or shortening, and water. Leavening agents such as baking soda or ammonium bicarbonate, salt, milk solids, emulsifiers, flavors and inclusions such as chocolate chips or nuts are added depending on the recipe. Ingredient quality directly affects the final product.

Hard dough is developed with more water and longer mixing, giving a firm, elastic dough. It is used for crackers and semi-sweet biscuits like Marie. Soft dough has higher fat and sugar and less water, so it is mixed briefly. It is used for cookies and short-dough biscuits with a crumbly, tender bite.

Mixing blends the ingredients evenly and develops the gluten structure. Mixing time, speed and dough temperature all influence dough consistency, biscuit texture and how well it runs on the forming line. Under-mixed or over-mixed dough can cause uneven shape, cracking or hard biscuits.

The common methods are rotary moulding, rotary cutting, wire-cutting and depositing. Rotary moulding is used for embossed biscuits, rotary cutting for laminated crackers, and wire-cutting or depositing for soft cookies. The method is chosen based on dough type, biscuit design and production speed.

Baking temperatures typically range from about 180°C to 250°C, and baking time is usually a few minutes, depending on biscuit type, thickness and oven design. Biscuits are generally baked in tunnel ovens with multiple heating zones, which control moisture loss, color and crispness.

Biscuits leave the oven hot and fragile. Cooling on a conveyor lets the temperature and moisture settle, so the biscuits become firm and stable. Packing them while warm can trap moisture, make them soft or soggy, cause cracking, and shorten shelf life.

Manufacturers typically check raw material quality, dough temperature and consistency, biscuit weight and dimensions, color, moisture content and texture. Finished packs are also checked for correct weight, seal quality and labeling. Metal detectors and checkweighers are commonly used to meet food safety standards.

A typical plant includes flour sifters, mixers, dough sheeters or laminators, forming machines, a tunnel oven, cooling conveyors, stacking equipment and packaging machines. Packaging lines often add labeling and coding units to print batch numbers and expiry dates.

Shelf life depends on low final moisture, proper baking and cooling, and good packaging. Moisture-barrier films, sealed wrappers and nitrogen flushing for some products help prevent softening and rancidity. Biscuits stored in cool, dry conditions typically stay fresh for several months, and the exact period depends on the formulation and pack type.
