How does a biscuit production line work? Crispy and delicious biscuits, transformed from basic flour, sugar, and oil into beautifully packaged goods in the hands of consumers, represent an automated process in modern food industry.
A complete biscuit production line consists of several core interconnected steps: raw material processing, biscuit forming, biscuit baking, biscuit oil spraying, biscuit cooling, and biscuit packaging. Below is a detailed explanation of how this production line works.
How Does A Biscuit Production Line Work?
1. Raw Material Mixing and Conveying: The process begins in the mixing section. Flour, sugar, oil, water, and other ingredients are poured into the dough mixer according to a pre-set formula. This machine, through precise control, mixes the dry and wet ingredients into a uniform dough with the right consistency, ensuring consistent flavor and texture in every batch of biscuits. The mixed dough is then smoothly conveyed to the next station via a conveyor belt.
2. Biscuit Shaping: This is the crucial step in shaping the biscuits, and the entire process requires no manual intervention. Different shaping equipment is used depending on the product type:
- Roller Printing Machine: Suitable for resilient dough. The dough is pressed between the machine's rollers and the mold into biscuit blanks with various patterns, and then automatically and neatly falls onto the continuously running oven steel belt or mesh belt.
- Roller Cutting Machine: First, the dough is pressed into a uniform strip by rollers, then the mold rollers precisely print out the shape, simultaneously separating the biscuit blank from the scraps. The scraps are automatically recycled, achieving efficient and waste-free continuous production.
- Wire cutter: Commonly used for shortbread dough (such as American biscuits). The machine extrudes the dough through a die and automatically cuts it into uniformly sized pieces with a wire, which fall directly onto a conveyor belt.
The shaped biscuit dough pieces are arranged at precise intervals on the conveyor belt, ready for baking.
3. Biscuit Baking and Cooling: The conveyor belt carrying the biscuit dough pieces slowly passes through a long tunnel oven. Here, a computer-controlled temperature, humidity, and hot air circulation system allows the biscuits to undergo a perfect "transformation": moisture evaporates, the color turns golden, and flavor compounds are generated. Freshly baked biscuits are soft and very hot, and must immediately enter the cooling line (usually a long, straight cooling belt) to cool and set under natural air circulation at room temperature, becoming crisp and easier to package later.
4.Biscuit Decoration and Packaging: After cooling, the biscuits undergo decoration according to the product design, such as being filled with butter filling using a filling machine, or coated with a sweet chocolate coating machine. Finally, the biscuits are fed into an automatic packaging machine, where they undergo a series of processes including weighing, bagging, nitrogen filling (for preservation), sealing, and coding, ultimately becoming the products we see on the shelves. The entire production line also integrates metal detectors and checkweighers, providing a final, solid guarantee for food safety.
