With the rise of the global trend of healthy eating, cereal bars have become a popular choice for breakfast replacements, exercise supplements, and healthy snacks due to their rich nutrition, portability, and ease of consumption. One of the core technological equipment supporting the industrial production of this food is the grain stick forming machine. This article will comprehensively analyze how this device converts raw grains into standardized food, from its working principle, technical characteristics to industry applications.
1、 Definition and core functions of grain stick forming machine
Grain stick forming machine is an automated food processing equipment specifically designed to press mixed raw materials such as oats, quinoa, nuts, and dried fruits into regular shapes (such as rectangular or cylindrical) through specific processes. Its core function is to achieve the accurate proportion of raw materials, efficient molding, cutting and packaging of the whole process operation, to meet the strict requirements of industrial production on efficiency, hygiene and product consistency.
2、 Working principle and technical process of equipment
1. Raw material pretreatment and mixing
The front end of the equipment is equipped with a high-precision mixing system, which can evenly mix dry raw materials (grains, nuts) and binders (honey, syrup) to ensure stable proportioning for each batch. Some high-end models integrate temperature control modules, which can heat the raw materials to enhance the bonding effect.
2. Molding process
-Mold pressing: The mixture enters the forming mold through a conveyor belt and is subjected to 5-15 tons of pressure through a hydraulic or pneumatic system to form a dense block structure. The mold can be quickly replaced and supports the production of products of different sizes (common specifications: 30g-100g/strip) and cross-sectional shapes.
-* * Cold pressing technology * * (optional): For sugar free, low calorie healthy formulas, low-temperature pressing technology is used to retain the natural nutritional components of ingredients.
3. Cutting and shaping
After forming, the continuous block material is divided into independent strips with millimeter level accuracy by a rotating blade or laser cutting system, and the edges are trimmed synchronously to avoid debris generation.
4. Cooling and packaging
The cut grain bars enter the cooling tunnel for cooling and shaping, and are then sealed with aluminum foil or plastic film by an automatic packaging machine. Some production lines integrate metal detection and weight detection systems to ensure product safety and compliance.
3、 Core technical modules of the equipment
Using PLC or industrial computer control, parameters such as pressure, temperature, cutting speed, etc. can be preset to monitor production data in real time. The touch screen interface supports one click switching of formulas, adapting to flexible production of multiple varieties.
4、 Application scenarios and market value
Food processing factory: meets the large-scale OEM production needs of international brands such as Kind and Clif Bar.
Innovation in Healthy Catering: Supports the addition of functional ingredients such as chia seeds and collagen to meet the needs of segmented markets such as ketogenic and high protein.
Emerging market expansion: In Southeast Asia, the Middle East, and other regions, the equipment can adjust the formula to suit local tastes (such as coconut and spicy cereal bars).
As a bridge connecting health concepts and large-scale manufacturing, the technological innovation of cereal bar forming machines continues to drive the upgrading of the food industry. From precise nutrition ratio to flexible production, from energy consumption optimization to intelligent control, this equipment is not only a guarantee of production efficiency, but also a strategic asset for food enterprises to seize the healthy economic track. In the future, with the integration of personalized nutrition and intelligent manufacturing technology, grain stick production may enter a new era of “thousands of people, thousands of faces”.
