I. Complete Production Technological Process for Fried Puffed Food: Full‑link Automation for One‑stop Output of Fried Puffed Snacks

The full‑automatic fried puffed‑food production line of Jinan Dingrun features mature technology with automated interconnection of all equipment and minimal manual intervention, fully replicating industrial mass‑production standards. The complete production line consists of ten core working procedures: powder mixing, closed feeding, twin‑screw extrusion puffing, cutting & forming, baking pretreatment, continuous frying, centrifugal de‑oiling, air cooling, drum seasoning and finished‑product packaging. Compatible with corn flour, rice flour, wheat flour, various starches, grain powder and other raw materials, the equipment can mass‑produce fried puffed leisure snacks such as shell crisps, pizza rolls, bugles, sharp‑angle crisps, rice crackers, salad strips, spiral puffed blanks and triangular chips.

1. Powder Mixing ProcessSpecial full‑automatic powder‑mixing equipment is adopted to precisely proportion powder materials and water according to food formulas and perform high‑speed stirring and blending. The mixed materials show uniform humidity with fine texture free of agglomerates. Adjustable stirring speed brings high mixing efficiency, effectively avoiding common drawbacks of manual mixing such as uneven humidity and insufficient blending. It guarantees consistent taste of final puffed and fried products from the raw‑material stage and lays a solid foundation for the subsequent puffing procedure.
2. Feeding ProcessStirred raw materials are automatically delivered to the puffing host via closed screw conveyors. The fully‑enclosed conveying structure prevents dust emission and raw‑material spillage, complying with food‑safety production standards. Continuous and stable feeding ensures non‑stop operation of the whole production line.
3. Extrusion Puffing ProcessAs the core section of the whole line, materials enter the twin‑screw puffing host and achieve gelatinization, melting and puffing under high temperature, high pressure and high shear force. The equipment precisely regulates host temperature and pressure parameters to fully gelatinize materials and form uniform porous internal structures. By replacing molds of different specifications, various special‑shaped blanks including shells, spirals, five‑pointed stars, tubes and sheets can be produced to meet diversified shape requirements for fried snacks.
4. Cutting & Forming ProcessAfter puffed materials are extruded, intelligent high‑speed rotary cutters perform automatic cutting according to preset dimensions, delivering smooth cutting edges and uniformly‑sized blanks with few fragments and defective goods. Cutting speed can be flexibly adjusted according to host capacity to match production requirements of different output volumes and blank specifications.
5. Continuous Frying ProcessDried blanks are conveyed into the full‑automatic continuous fryer. The equipment supports multiple heating modes including electric heating and gas heating with intelligent constant oil‑temperature control. Equipped with oil‑residue filtering and circulating oil‑filtering systems, it filters residues in oil in a timely manner, extending edible‑oil service life and reducing oil‑replacement costs, so as to produce golden‑colored and crispy fried finished products.
6. Centrifugal De‑oiling ProcessFried semi‑finished products are sent to centrifugal de‑oiling equipment. High‑speed vibratory centrifugation removes excess surface oil, lowers oil content of finished goods and prevents product adhesion caused by oil exudation. It improves snack taste and helps extend shelf life.
7. Air‑cooling ProcessHigh‑temperature finished goods after de‑oiling are transported to the air‑cooling conveyor line. Circulating ambient air dissipates heat evenly and quickly cools products down to room temperature. Cooled products are dry, crispy, non‑soft and moisture‑resistant, getting well‑prepared for subsequent seasoning and packaging. It avoids deterioration caused by water‑vapor condensation inside packaging bags and improves the qualified‑product rate.
8. Drum Seasoning ProcessCooled products enter the drum seasoning machine. Powder seasonings adhere evenly to snack surfaces with sufficient and uniform coating, effectively solving problems of local over‑seasoning or insufficient flavor. It supports multi‑flavor production such as spicy, cheese, barbecue and sea‑taste flavors.

9. Finished‑product Packaging ProcessSeasoned finished products connect with automatic packaging equipment for weighing, bag‑filling and sealing to obtain final goods, realizing full‑automatic production from powder raw materials to bagged snacks.

   
   

II. Core Equipment Advantages: Intelligent, Energy‑saving & Multi‑functional to Solve Mass‑production Pain Points of Fried Puffed Food

The new‑generation complete fried puffed‑food production line from Dingrun is iteratively upgraded targeting real‑world production pain points of domestic food factories. It overcomes disadvantages of traditional equipment such as high energy consumption, unstable blank forming, uncontrollable oil absorption during frying, complicated operation and troublesome maintenance. It boasts five core strengths: high automation, controllable energy consumption, high qualified‑product rate, multi‑purpose function and easy maintenance.

The host screws and barrels are made of high‑wear‑resistant alloy materials featured with high‑temperature resistance and corrosion resistance. They support 24‑hour non‑stop factory production with long service life, greatly cutting later‑stage spare‑part replacement and maintenance costs. The whole line is equipped with a PLC variable‑frequency intelligent control system and visual man‑machine interface. Parameters can be set with one‑click operation; temperature, rotating speed and conveying speed can be fine‑tuned precisely. Ordinary workers can operate it after simple training, lowering dependence on skilled technicians.

Full‑automatic assembly‑line operation greatly reduces labor posts and labor costs. Closed‑loop control of process parameters ensures stable puffing degree of blanks, drying moisture content and frying oil temperature, achieving a finished‑product qualification rate of over 99 % and minimizing raw‑material loss. With strong compatibility, the same production line can switch among more than ten kinds of fried puffed‑snack products simply by replacing molds and adjusting process parameters, helping manufacturers quickly launch new‑market items and enrich product portfolios. Multi‑stage oil‑filtering systems are configured for the frying unit to reduce oil consumption; heat‑preservation structures are adopted for baking and host heating modules. Comprehensive energy consumption is obviously lower than traditional equipment, helping factories control long‑term production costs. All food‑contact components are made of food‑grade stainless steel for easy disassembly and cleaning, satisfying sanitation‑audit requirements for food plants.
