I. What Are Fried Foods? Diverse Applications Cover Full-Scenario Needs

1. Leisure Snack Market: Producing fried shrimp sticks, French fries, potato chips, fried puffed dried tofu, seasoned fried grain sticks, etc., to meet the daily consumption needs of the public for drama-watching and social sharing. These products are core traffic-driving categories in supermarkets and e-commerce platforms;
2. Specialty Food Market: Processing local specialty fried snacks, fried wheat products, fried nuts, etc., helping enterprises create differentiated products and seize niche market segments;
3. Catering Supporting Market: Making fried snacks and fried semi-finished ingredients to adapt to the fast food preparation needs of catering stores and takeout platforms, improving the operational efficiency of catering businesses.

II. Comparison of Three Fried Snack Production Processes – Jinan Dingrun’s Extruder Process Stands Out

1. Traditional Direct Frying Process: Ingredients are directly put into high-temperature oil for frying. The process is simple but has obvious drawbacks – large oil consumption and high oil absorption rate of raw materials (usually 25%-35%), which not only increases raw material costs but also incurs environmental treatment fees due to repeated use of oil. Meanwhile, production efficiency is low, and problems such as uneven frying and inconsistent texture are common, leaving limited room for product premium.
2. Post-Baking Frying Process: Ingredients are first baked for shaping, then briefly fried for flavor enhancement. Although it can reduce oil absorption to a certain extent, the production process is cumbersome, energy consumption doubles, and the baked ingredients have a hard texture, resulting in insufficient crispness after frying, which fails to meet the public’s core demand for texture. It has low cost-effectiveness for large-scale production.
3. Post-Extrusion Puffing Frying Process (Recommended by Jinan Dingrun): Raw materials undergo pre-puffing treatment via Jinan Dingrun’s puffing extruder before entering the frying stage. It is the optimal solution balancing texture, efficiency, and cost, with core advantages directly addressing profit pain points:
4. Significantly Reduced Costs: Jinan Dingrun’s puffing extruder enables raw materials to puff in advance to form a porous structure, reducing the oil absorption rate to 12%-18% during frying and saving more than 40% of oil costs directly. Meanwhile, the equipment’s energy consumption is only 60% of that of traditional processes. Combined with adaptability to cheap by-products such as broken rice and wheat bran, the comprehensive cost for the same output is reduced by more than 35%.
5. Both High Efficiency and Quality: Jinan Dingrun’s twin-screw puffing extruder supports continuous production, with a capacity of 500kg-5000kg per hour, far exceeding traditional processes. Pre-puffing ensures uniform heating of ingredients during frying, resulting in a crispy outer layer and soft inner texture, with strong texture stability. The product qualification rate is increased to over 98%, helping create high-quality best-selling products.
6. Flexible Product Iteration: By replacing molds, Jinan Dingrun’s puffing extruder can produce puffed blanks in various shapes such as strips, flakes, and balls. Combined with different seasoning schemes, it can easily switch fried snack categories, quickly respond to popular market trends, and expand product lines without additional equipment investment.
7. Lower Environmental Pressure: Reduced oil absorption leads to a 60% decrease in waste oil production, which not only saves waste oil treatment costs but also complies with environmental policies, avoiding production disruptions due to environmental issues and realizing sustainable operations.

   

III. Complete Production Process of Jinan Dingrun’s Fried Snack Puffing Extruder

1. Raw Material Pretreatment and Mixing: Jinan Dingrun is equipped with high-speed mixing equipment, which accurately mixes raw materials such as grain flour, tuber flour, and soybean flour with water and seasonings, controlling the moisture content of raw materials at 12%-16% to ensure uniform subsequent puffing effect. At the same time, dietary fiber, protein powder, and other nutrients can be added to adapt to the healthy consumption trend.
2. Extrusion Puffing and Shaping: Raw materials enter Jinan Dingrun’s twin-screw puffing extruder, where starch gelatinization and protein denaturation are completed under high temperature (120-180℃) and high pressure (3-5MPa). After being extruded through custom molds, the pressure drops sharply to achieve puffing, forming porous blanks. Molds can be quickly replaced as needed to adapt to different product shape requirements.
3. Cutting and Pre-Drying: The puffed blanks are cut into preset lengths and specifications by Jinan Dingrun’s high-speed precision cutting knife, then surface moisture is removed by a mesh belt pre-dryer to reduce oil absorption in subsequent frying. It also improves the shaping effect of blanks, avoiding deformation and adhesion during frying.
4. Precise Frying and Deoiling: The pre-dried blanks enter a continuous frying equipment. Jinan Dingrun’s production line can accurately control frying temperature (160-180℃) and time to ensure uniform frying. After frying, professional deoiling equipment removes excess surface oil, further reducing oil content and improving product texture and health attributes.
5. Seasoning and Packaging: Equipped with Jinan Dingrun’s supporting seasoning equipment, it achieves uniform coating through dry, wet, and other methods, realizing various flavors such as spicy, barbecue, and tomato. Finally, automatic packaging equipment completes nitrogen-filled sealed packaging to extend shelf life. The fully automated operation reduces product loss and improves packaging efficiency.
