The development trends of cereal puffed foods involve process, equipment selection, and operational management issues in food processing and production equipment.The actual solution should be confirmed based on raw material characteristics, target product specifications, production scale, and on-site conditions, and should not be determined solely by single equipment parameters.

Key Trends in the Development of Extruded Cereal Snacks

Puffed snacks have long been highly popular among consumers due to their good texture, unique and diverse flavors, portability, convenience of consumption, and long shelf life.

Nutritional Cereal Puffed Food

Fat, carbohydrates, and protein are the main components of traditional puffed foods.From a compositional standpoint, it is a high-fat, high-calorie, and low-crude-fiber food.In addition, most traditional puffed snacks contain large amounts of monosodium glutamate, salt, and food additives.Long-term, high-volume consumption can lead to excessive intake of fats and calories, insufficient nutrient intake, and an increased risk of obesity.As consumers' awareness continues to grow, food nutrition has become the primary factor they consider when making purchasing decisions.For puffed food products, the primary task in industry development is to address nutritional issues and change the public perception that they are “junk food.”

Low-energy cereal puffed food

From the perspective of raw material composition, traditional cereal-based puffed foods are high in fat and calories, and low in fiber.Long-term consumption can lead to excessive intake of fats and calories, insufficient nutrient intake, and an increased risk of obesity.Therefore, low energy is also an important development direction for snack foods.

Many cereal-based puffed snacks are processed using frying techniques, making energy control closely related to their oil content, which in turn depends on the oil absorption during the processing.By selecting raw materials with high solid content, or by pre-drying or partially drying the raw materials before frying, the frying time can be shortened.To control oil absorption during the frying process, frying temperature is also critical.Raw materials should be fried at the highest possible temperature to shorten frying time and reduce oil absorption.Furthermore, the larger the surface area of the raw material, the higher the oil absorption.Therefore, the oil content of flake-shaped products is relatively low.

High-temperature extrusion technology

High-temperature puffing is achieved by circulating hot air to vaporize moisture, which in turn drives the overall expansion of the material.Currently, there are cereal puffing foods produced using high-temperature extrusion technology, such as the high-temperature extruder (large hot air equipment) from Degu Machinery.

Compared to fried puffed snacks, high-temperature puffed products have lower oil content, with finished products being oil-free or low-oil, and offering a crispy and delicious texture.This technology offers advantages such as rapid heating, short processing time, high product quality, uniform heating, and a small equipment footprint.It is foreseeable that high-temperature extrusion technology is a development direction for extruded food production technology.

Grain is the primary food resource for human survival, and the grain processing industry bears the important responsibility of providing basic dietary sources and safeguarding human health.The global food processing industry is currently advancing toward the application of modern high-tech innovations, the in-depth development of limited grain resources, and the enhancement of the added value of grain products.

Currently, the application of extrusion technology for producing extruded snacks is still in its early stages; therefore, it is essential to actively advance research on extrusion theory and technology, and to continuously develop new products.We believe that, with the advancement of the aforementioned initiatives and the improvement in living standards, puffed foods that meet the needs of the general public will undoubtedly experience rapid development.

What conditions should be considered during implementation or selection?

First, it is essential to clarify the product type, raw material state, formulation direction, and expected finished product requirements.For projects involving extrusion, forming, drying, frying, conveying, seasoning, or packaging, the processing capacity and cycle time of each stage must be matched to avoid discrepancies between individual equipment capacity and the overall line requirements.

Secondly, the installation plan should be evaluated in conjunction with the workshop's spatial layout and utility conditions, including power supply, water supply, steam, or gas.Equipment configuration should also take into account long-term operational factors such as cleaning, maintenance, safety protection, spare parts supply, and operator training.Any process or equipment capabilities mentioned in this document are for reference only in the context of solution discussions and preliminary assessments.Specific model numbers, power ratings, production capacities, temperatures, and times shall be subject to the formal technical proposal and the results of trial runs or on-site verification.

Frequently Asked Questions

Can the equipment be determined directly based on the standard configuration?

Not recommended.Different raw materials, product structures, target production capacities, and downstream processes can affect the equipment configuration.It is more prudent to confirm the product and process conditions before proceeding with the configuration assessment.

How to obtain more targeted advice?

It is recommended to prepare product images or sample information, raw material and formulation guidelines, target production capacity, existing workshop conditions, and planned downstream equipment configurations.Dayi Machinery can further discuss the applicable process routes and equipment configuration options based on this.
