Project Introduction
Potato-based crispy snacks and ready-to-eat fries enjoy steady global consumer demand, delivering stable profit margins for small and medium food processors. Many new entrepreneurs want to build their own snack plant but get confused by complicated equipment matching, unclear process flows and high initial investment risks. The modular potato processing lines manufactured by Zhengzhou Runxiang solve these core pain points effectively.
Every food-contact part of the whole line adopts food-grade 304 stainless steel, fully complying with international food export inspection standards. One integrated line can manufacture plain potato chips, crinkle-cut crisps, fresh fries, sweet potato chips, lotus root crisps, carrot crisps and various vegetable crisp snacks. By adding an individual quick freezing unit (IQF freezer), operators can expand frozen french fry production to achieve year-round continuous operation without seasonal production downtime.
This tutorial follows the structural layout of the poultry feed pellet production guide, systematically covering factory pre-opening preparation, full set equipment configuration, applicable raw material categories, standardized production workflows, daily operation & maintenance management, plus exclusive competitive strengths of Runxiang potato processing lines.

Multi-Purpose Precision Slicer & Cutter Comes with interchangeable multi-specification cutting blades to freely switch production of flat chips, wavy crisps, thick-cut fries, thin-cut fries and assorted vegetable slices. Super sharp cutting blades deliver neat, crack-free cuts with extremely low product breakage rate, supporting uninterrupted continuous feeding without jamming.《Learn more / Contact us》
Thermostatic Blanching & Color Protection Machine Adopts enclosed hot water bath design with independent digital temperature control panel. After slicing and cutting, raw materials go through rapid constant-temperature blanching to eliminate free surface starch, block enzymatic browning and avoid adhesion during frying, ensuring consistent golden color across all production batches.
High-Speed Centrifugal Dewatering Machine After blanching, raw materials carry massive surface moisture. This spin-drying unit thoroughly removes residual water, eliminating oil splashing safety hazards during frying, lowering oil absorption rate of finished snacks and extending edible oil service life to reduce long-term operating expenses.《Learn more / Contact us》
Oil-Water Separation Energy-Saving Fryer (Core Central Equipment) Adopts advanced layered oil-water separation technology. Food crumbs sink to the bottom water layer instead of carbonizing in high-temperature oil, which keeps cooking oil clean and drastically prolongs oil replacement cycles. Intelligent temperature control panel stabilizes frying temperature between 160℃–180℃ for uniform heating, preventing scorching or undercooked products. The semi-automatic model features manually liftable material baskets, while the fully automatic version uses mesh belt continuous conveying.《Learn more / Contact us》
Secondary Centrifugal De-Oiling Machine Freshly fried snacks carry excess surface grease. Secondary high-speed centrifugal de-oiling strips redundant oil, delivering light, non-greasy crisp texture. Less surface oil also slows moisture absorption from air, greatly extending the shelf life for long-distance domestic distribution and overseas export shipments.《Learn more / Contact us》
Octagonal Closed Drum Seasoning Machine Slow-speed rotating sealed octagonal drum evenly coats flavor powder on every snack surface. The fully sealed structure avoids seasoning dust flying and material waste, reduces product fragmentation, and guarantees uniform taste without salty or bland individual pieces in one batch.《Learn more / Contact us》
Circulating Air Cooling Conveyor Multi-layer air circulation cooling tunnel rapidly reduces the temperature of hot seasoned snacks to room temperature. It prevents hot steam trapped inside packaging bags from softening crisps and triggering early deterioration, locking stable crispy texture for finished goods.《Learn more / Contact us》
Nitrogen-Filled Vacuum Packaging Machine Supports two packaging modes: regular vacuum packaging or nitrogen flushing fresh-keeping packaging. Nitrogen filling isolates air and moisture to prevent oxidation and stale texture, with tight, tidy sealing edges meeting retail supermarket shelf standards and export container shipment requirements.《Learn more / Contact us》
