China’s domestic puffed‑snack consumption market keeps evolving. Consumers set higher requirements for product appearance, flavor and product diversity, and food manufacturers’ demand for flexible and integrated complete‑set processing equipment continues to rise. Devoted to the R&D and manufacturing of puffing equipment, JINAN RUN MACHINERY CO., LTD has independently developed a complete production line for sandwich rice snacks and rice crackers based on proven puffing technology. It realizes integrated operation from raw‑material handling to finished‑product output and supports the production of multiple categories of puffed foods. With stable equipment performance and comprehensive supporting services, it assists snack‑food enterprises in realizing differentiated and large‑scale production.

As the snack‑food sector develops rapidly and product renewal accelerates, many manufacturers are confronted with challenges such as single‑product equipment, cumbersome commissioning for product changeover, and difficulty in launching diversified products with varied shapes and flavors in a short cycle. The traditional production mode assembled from separate standalone machines suffers from poor process connection and high costs for product iteration and modification. To address such industry pain points, drawing on its technical accumulation in puffing equipment, JINAN RUN MACHINERY CO., LTD has developed the sandwich‑rice‑snack and rice‑cracker production line balancing universality and flexibility to satisfy enterprises’ diversified product‑layout requirements.

This complete puffed‑food production line delivers end‑to‑end integrated processing, covering the full workflow including raw‑material batching, material conveying, extrusion‑puffing forming, baking and cooking, flavor spraying and finished‑product discharging. The equipment set comprises powder mixer, screw elevator, twin‑screw main extruder, sandwich filling machine, multi‑function shaper, elevator, oven and automatic seasoning line. All units operate in well‑coordinated linkage with high automation and smooth continuous workflow.

Boasting strong product compatibility, the line mainly produces sandwich rice snacks and rice crackers, and can also manufacture fragrant rice crackers, sandwich rolls, sandwich biscuits and crispy cookies. It is also applicable to processing grain porridge, nutritional powder and other products. When producing ordinary puffed snacks, manufacturers may add seasonings, compliant food additives, food colorants and other raw materials at the powder‑mixing stage according to product formulas. Products of various shapes can be obtained by replacing dies of different specifications, and diverse flavors can be achieved with various seasoning auxiliary materials. One single set of equipment can realize differentiated production in shape, flavor and color for similar products, helping manufacturers enrich product portfolios and cut investment costs for additional production lines.

Beyond hardware, comprehensive on‑site implementation services guarantee smooth project commissioning. JINAN RUN MACHINERY CO., LTD provides reference basic process formulas to shorten enterprises’ early‑stage R&D and trial‑and‑error cycles. After equipment purchase, on‑site installation and commissioning services are provided. Professional technicians deliver hands‑on training for plant operators to help them master key points of equipment operation and daily maintenance, so that the production line can be quickly put into normal operation.

A sound after‑sales guarantee system is also available. The complete set of equipment enjoys a one‑year full‑machine warranty. After the warranty period expires, genuine spare parts can still be purchased at favorable prices, effectively solving spare‑part supply issues for later‑stage equipment maintenance and ensuring long‑term stable line operation.

As a manufacturer specializing in puffed‑food processing machinery, JINAN RUN MACHINERY CO., LTD keeps optimizing extrusion‑puffing equipment technologies oriented toward actual market production demands. In the future, the enterprise will further improve the flexible‑production capability and iterate equipment performance, supplying well‑adapted domestic complete‑set equipment for the snack‑food industry. It helps food enterprises reduce costs, improve efficiency and accelerate product innovation, and promotes high‑quality development of the puffed‑snack industry.
