Introduction to Automatic Biscuit Production Line
An Automatic Biscuit Production Line is a fully integrated system designed for large-scale and continuous biscuit manufacturing. It streamlines the entire biscuit-making process—from dough mixing and rolling to moulding, baking, cooling, and packaging. As global food manufacturers focus on efficiency, hygiene, and consistent product quality, the demand for fully automatic biscuit making lines and industrial biscuit production equipment continues to rise.
Compared with traditional semi-automatic or manual methods, a modern commercial biscuit production line ensures higher productivity, stable quality control, reduced labor costs, and improved food safety standards. Whether producing hard biscuits, soft biscuits, cookies, butter biscuits, Marie biscuits or cream crackers, an automated line can adapt to various recipes, shapes, and production requirements.
How an Automatic Biscuit Production Line Works
A typical Automatic Biscuit Production Line integrates multiple machines into a continuous, synchronized system. Below is the complete workflow:
1. Dough Preparation System
This includes the dough mixer, vertical or horizontal dough kneader, and fermentation tank (optional).
- Ensures uniform hydration of ingredients
- Supports different biscuit formulas
- Provides continuous feeding to maintain uninterrupted production

2. Dough Feeding & Sheeting Section
The prepared dough is transported to the dough sheeter where rollers press the dough into a consistent sheet.
- Multi-roller design ensures smooth surface
- Adjustable thickness for different biscuit types

3. Biscuit Forming Machine (Moulding Unit)
The dough sheet enters the rotary moulder or cutting machine, depending on biscuit type:
- Rotary moulder → Soft, sticky, or grain biscuits
- Rotary cutter → Hard biscuits with precise shapes
Available shapes include round, square, animal shapes, flower patterns, and customized molds.

4. Baking Line (Tunnel Oven)
The shaped dough pieces move into a gas, diesel, electric or hybrid tunnel oven.
- Long tunnel structure ensures continuous baking
- Adjustable temperature zones
- High-efficiency heat circulation
This is considered the core of an automatic biscuit baking line because it determines texture, crispiness, and color.

5. Oil Spraying & Cooling Conveyor
After baking:
- A fine mist of edible oil can be applied for shine and flavor
- Stainless-steel cooling conveyors allow biscuits to cool naturally
- Ensures moisture stability before packaging

6. Packaging Machine
The final section integrates automatic biscuit packing machines, including:
- Pillow packing machine
- On-edge biscuit packaging system
- Family pack bundling machine
Automated packing prevents contamination and improves logistics efficiency.

Advantages of the Automatic Biscuit Production Line
Choosing a Fully Automatic Biscuit Production Line offers major benefits for commercial manufacturers:
1. High Production Capacity
The line can produce hundreds of kilograms of biscuits per hour and run continuously for long shifts.
2. Consistent Quality
Automated control ensures uniform baking temperature, moisture level, color, and size.
3. Lower Labor Costs
The entire system requires only a few operators to monitor and maintain.
4. Versatility
Supports different biscuit categories:
- Hard biscuits
- Soft biscuits
- Cookies
- Crackers
- Cream biscuits
5. Hygienic and Easy to Clean
Food-grade stainless steel ensures compliance with international hygiene standards.
6. Customizable Layout
Manufacturers can configure the line length, tunnel oven size, packaging model, and mould shape.
Types of Automatic Biscuit Production Lines
Different factories require different configurations. Common types include:
1. Small-Scale Automatic Biscuit Production Line
