Exploring the biscuit production line

In our daily snack list, biscuits occupy an important place with their crispy texture and rich taste. But are you curious about how these small biscuits are transformed from the initial raw materials step by step into the mouth-watering delicacies on the shelves? Today, let us walk into the modern biscuit production line and uncover the wonderful secrets behind it.

Production characteristics of different types of biscuit production line

According to different formulas and production processes, biscuits are mainly divided into two categories: tough biscuits and crisp biscuits. They have their own characteristics in the production process:

1.Tough biscuits: The ratio of sugar and oil is relatively low, generally less than 30% sugar and less than 20% oil. During production, the hot powder process is required to adjust the powder, and the dough adjustment time is relatively long to form a dough with strong toughness and extensibility. When forming, stamping or roller cutting is usually used. The stamping mold is concave and has pinholes. The surface of the biscuits produced in this way is flat and smooth, the cross-sectional structure is layered, and the taste is crispy and chewy.

2.Crisp biscuits: They are high-fat biscuits, with a large amount of oil, generally 14% - 30% of the flour. The amount of oil in some special products can be as high as about 50%. The cold powder process is used to adjust the powder, the dough adjustment time is short, the dough has strong plasticity but low toughness. The molding is mostly roller printing, the stamping mold is convex, without pinholes, and the biscuits made have obvious patterns, fine structure, and loose taste.

3.In addition, there are many types of fermented (soda) biscuits, crackers, cookies, sandwich biscuits, wafer biscuits, etc., each of which has its own unique production process and equipment requirements. For example, fermented (soda) biscuits use yeast as a loosening agent and need to go through processes such as fermentation, powder mixing, rolling, lamination, and baking; cookies are formed by extrusion, extrusion, wire cutting, etc., with high fat content, three-dimensional patterns or regular ripples on the surface.

Product Description of biscuit production line

The fully automatic biscuit making machine is a professional biscuit production equipment, which is mainly composed of a dough mixer, a compound rolling and shaping machine, an oven, an oil sprayer, a cooling machine,and a packaging machine. This type of biscuit production line offers various models, favorable factory prices, and guaranteed quality. It can produce hard biscuits, soft biscuits, soda crackers, sandwich biscuits, etc.

Working Process of the Biscuit Production Line​

1. Dough mixing machine: Wheat flour, sugar, oil, eggs, dairy products and other raw materials are mixed here according to precise formulas to provide uniform dough for subsequent production links. During the mixing process, the temperature and time are precisely controlled to prevent the raw materials from overheating or over-mixing, ensuring the texture and taste of the dough.
2. Compound rolling and shaping machine:Common ones include punching and forming machines, roller cutting and forming machines, roller printing and forming machines, etc. These equipment process the dough into various shapes according to different biscuit types and shape requirements. For example, tough biscuits are often punched or rolled, and their mold shapes are mostly concave flowers with pinholes on the surface; crisp biscuits are mostly rolled, and the mold shapes are mostly convex flowers with obvious patterns. The design and adjustment of the mold are crucial in this link. Different molds can produce biscuits of various shapes and flavors, such as round, square, animal shapes, etc.
3. Oven:Tunnel hot air circulation oven is a common baking equipment. It uses precise temperature control and timing functions to bake the formed biscuits in the best condition. The baking temperature and time will be adjusted according to the type and thickness of the biscuits to ensure that the biscuits are crispy and delicious without being overbaked. Generally speaking, the baking temperature is between 200-300℃, and the time ranges from a few minutes to more than ten minutes.

4.Oil sprayer:The oil sprayer can evenly spray oil on the surface of the baked biscuits, making the biscuits more attractive in color and richer in taste.

5.Cooling machine:the cooling line is used to cool the baked biscuits to room temperature to prevent the biscuits from deforming or the packaging materials from being damaged due to excessive temperature during packaging.

6.Sorting machine :The sorting machine can sort the cooled biscuits so that they are neatly arranged for subsequent packaging.

7.Package machine:The automatic packaging machine completes the packaging of biscuits. It can realize a variety of packaging methods, such as independent packaging, multiple packaging per bag, etc. The packaging process not only improves production efficiency, but also ensures that each biscuit can be kept in the best condition and extend the shelf life of the biscuits.

Advantages of biscuit processing line

1.High degree of automation: From the automatic proportioning and mixing of raw materials to the molding, baking, cooling, and packaging of biscuits, the entire process can be automated, greatly reducing manual operations and improving production efficiency and product quality stability. At the same time, reducing manual contact also reduces the risk of food contamination and ensures food safety.

2.Precision control: The use of advanced control systems can accurately control parameters such as temperature, time, and speed during the production process. In the baking process, the temperature of each area of the oven can be accurately adjusted according to the needs of different biscuits to ensure that the biscuits are heated evenly and achieve the best baking effect.

3.Strong flexibility: By replacing molds and adjusting process parameters, the same production line can produce biscuits of various shapes, flavors, and formulas to meet the diverse needs of the market. This enables food manufacturers to respond quickly to market changes and launch new products.

4.High efficiency and energy saving: The use of energy-saving technologies and optimized production processes reduces energy consumption. For example, the oven uses efficient insulation materials and heat recovery systems to improve energy utilization and reduce production costs.

5.Hygiene and safety: The closed production environment is made of food-grade stainless steel to effectively avoid contamination and meet international food safety standards.
