How is Biscuit Made in Factories?

There are several important processes involved in biscuit production, but one of the most basic is baking. The baking process consists of several chambers, known as zones. Each chamber is independent, but large plants will have more than one. Inside the oven, biscuits travel on a mild steel continental wire mesh. They are then baked in an orderly process, undergoing a series of processes including raising, puffing, colouring, and de-gassing. The finished product should be a golden brown or dark chocolate, depending on the variety.


Biscuits are made by mixing various ingredients in dough. Once mixed together, biscuits are molded. They are then placed in a baking oven where the temperature is between 160 to 180 C. Baking is important to develop the biscuits’ structure, reduce their moisture content, and develop their distinctive colour. The finished biscuits are cooled and packaged to maintain their freshness and shape. The process of making biscuits in factories uses several different stages.

The production process of biscuits is complicated. The ingredients are mixed in the correct proportions in large mixers. The dough is then put in moulds and baked to create biscuits. After baking, the biscuits are filled with chocolate or cream. The production of biscuits is then finished by a machine that seals and packages the biscuits. A high-quality biscuit production machine plays a multiplier role by making the product look more appealing to consumers.


The process of biscuit making starts with the mixing of the ingredients in a mixer. The quantity of each ingredient, the order in which it is added, and the temperature will all play a role in the consistency of the dough. Other ingredients, such as sugar and fat, may also be added, such as ammonium bicarbonate, which adds height to biscuits. Once the ingredients are mixed well, they are shaped into biscuits, and baked to a desired thickness and size.

The surface of the biscuit is the first to change colour. This happens due to a chemical and physical reaction. The air bubbles in the dough absorb water and expand rapidly at high temperatures. This release of latent heat results in a significant increase in volume during baking. The temperature of the biscuits must be sufficiently high for the starch to gelatinise. In biscuits, this process begins at temperatures between fifty and sixty degC. However, the amount of water is seldom sufficient to fully gelatinise starch. Therefore, the dough pieces are only partially gelatinised by the time they reach 70degC. However, it may continue to develop colour until the biscuits reach around 95degC, depending on the type of dough and the method of heat transfer.


The manufacturing process of biscuits requires different stages of ingredient mixing, depositing, baking and cooling, and final packaging. Different packaging materials require different solutions and are used according to their functions. Various types of baking and cooling equipment are used, including mixers, moulders/cutters, carton taping machines, and end-of-line packaging equipment. Let’s take a look at some of the different types of packaging materials for biscuits.

Retailers prefer packaged biscuits because they enable uniform stacking on shelves and improve supermarkets’ visual appeal. A high-quality packaging design is important to increase sales. Using standout artwork and brand design can help biscuit manufacturers stand out from the competition. Here are some tips to help you improve your packaging design:


Biscuits are often made with the same basic ingredients: flour, butter, and sugar. Different types of flour provide varying textures and tastes. Some biscuits are made with wholemeal wheat flour, while others are made from refined flours, such as white flour. Biscuits also contain various ingredients, such as flavorings such as nuts or dried fruit. Biscuits are also commonly baked with milk or eggs, and have a high energy content.

The term biscuit came about in the Middle Ages. They were thin, cracker-like breads that were served with evening coffee and tea. The term biscuit is derived from the Latin word panis biscoctus, which means “double-baked.” Originally, biscuits were made by baking the dough twice before it was dried in a slow oven. Biscuits gained their name because of this process and later became known as “bisquite” in Middle English.


The manufacturing process begins with wet biscuits that are molded into shapes. They are then transferred to a massive oven. This oven, which ranges in temperature from 160 to 1800C, develops the biscuit’s structure, reduces moisture content, and develops its colour. After baking, the biscuits are transferred to a conveyor to cool and then to packaging. The cooling process helps preserve the biscuit’s quality, and it also extends its shelf life. After cooling, the biscuits are packed in different types of packaging, such as primary and secondary packs. Once packaged, they are placed in a corrugated fiber carton.

Biscuits are popular world-wide. Their ability to withstand long storage and the variety of shapes and flavours available make them the perfect snack to enjoy any time. The ingredients used in biscuit manufacturing are crucial to its success, so manufacturers must understand the chemistry between each of the ingredients. In the unorganised sector, biscuit manufacturing depends on human labor. Depending on the level of automation, biscuit manufacturing can be fully automated or highly manual.
