The twin-screw corn flakes production line of Jinan FLD Machinery Co., Ltd. is a modern breakfast grain processing solution that integrates efficiency, stability, flexibility, and energy conservation. Its core advantages are reflected in four dimensions: process technology, equipment performance, product quality, and automation control, fully meeting the needs of large-scale, standardized, and diversified corn flake production.
1. Core technology of corn flakes production line: twin-screw extrusion technology, efficient and stable
The corn flakes production line uses twin-screw extrusion puffing as the core process, replacing traditional single screw and steaming processes, to achieve the integration of raw material pretreatment, maturation, and molding, fundamentally improving production efficiency and product stability.
Building block combination screw: made of high-speed tool steel material, with a hardness of HRC ≥ 62, and specially heat-treated for wear resistance and fatigue resistance; Screw elements can be freely combined, which is suitable for corn flour, big Rice noodles, oat flour, miscellaneous grain flour and other grain raw materials, and can also handle functional formulas such as high fiber, low sugar, gluten free, to meet the needs of the healthy market.
Forced feeding and precise temperature control: The feeding system is variable frequency speed controlled, ensuring uniform and stable feeding; Segmented temperature control of the barrel (electric heating+water cooling), with temperature fluctuations of ≤± 1 ℃, ensures that the material completes gelatinization and maturation in the optimal temperature range, with a maturation rate of over 98%, avoiding taste defects caused by undercooking and overcooking.
Low failure and easy maintenance: The twin-screw has strong self-cleaning ability and automatically cleans the residual parts of the machine barrel during operation, reducing machine blockage and coking; The transmission system adopts direct motor connection, with no gearbox loss, low noise, high power transmission efficiency, equipment failure rate reduced by 40% compared to single screw line, and annual maintenance cost reduced by 30%.
2.Corn slice production line configuration: full process automation, controllable quality
The corn flakes production line covers the entire process of mixing, squeezing, pressing, drying, baking, seasoning, cooling, and packaging. The entire machine is made of stainless steel (304/316L) and meets food hygiene standards (ISO9001, CE certification). The closed-loop process has no secondary pollution.
Precision tablet pressing system: The dedicated tablet press adopts high-precision rollers with adjustable gaps (0.3-1.5mm), uniform tablet thickness, no sticky rollers, no broken edges, and a molding rate of ≥ 95%; Special coating on the roller surface, easy to clean, non stick, suitable for the production of corn flakes and miscellaneous grains of different thicknesses.
Multi stage drying+hot air baking: The first stage drying (50-70 ℃) removes surface moisture, and the second stage hot air baking (200-260 ℃) sets and enhances the brittleness of corn flakes at high temperatures, resulting in golden color, crispy texture, and good rehydration properties; The hot air circulation is uniform, without burning or uneven softness, and the consistency of the finished product's crispness is strong.
Intelligent seasoning system: drum/spray type seasoning machine, sugar, grease and flavoring materials are evenly sprayed, the adhesion rate is ≥ 90%, and there is no leakage or accumulation; It can achieve multi flavor switching such as sweet, salty, chocolate, and fruit flavors, and is suitable for the production of multiple categories such as ready to eat corn chips, breakfast cereal rings, and mixed grain crisps.
3.Capacity and adaptation: Multiple model coverage, flexible and efficient
We offer three standard models: SLG65III, SLG70III,and SLG85III, with a production capacity covering 100-450kg/h. We can customize large-scale production lines ranging from 500-1000kg/h as needed to meet the different production capacity needs of small and medium-sized processing plants to large food enterprises.
Capacity parameters (standard type):
SLG65III: installed power of 85.97kw, actual consumption of 56kw, production capacity of 100-150kg/h, size of 47 × 2 × 2.6m
SLG70III: installed power 119.06kw, actual consumption 82kw, production capacity 200-250kg/h, size 48.6 × 2 × 2.8m
SLG85III: Installed power 164.06kw, actual consumption 123kw, production capacity 350-450kg/h, size 49.4 × 2 × 3m
Flexible process switching: By replacing the extrusion mold, more than ten shapes such as corn flakes, oat balls, mixed grain flakes, grain balls, and star shaped flakes can be produced; By adjusting the formula and process parameters, functional products such as low sugar, high fiber, organic, and additive free can be produced. At most, one traditional corn flakes production line can be used, increasing the return on investment by 50%.
4. Energy saving and intelligence: low consumption, environmentally friendly, easy to operate
Energy saving design: Double screw extrusion curing has high efficiency, saving 30% energy compared to traditional cooking processes; The drying and baking system adopts waste heat recovery, with a heat utilization rate of 85%; Variable frequency drive matches the load, automatically reduces power during no-load/low load, and reduces overall energy consumption by 15-20% compared to similar equipment.
PLC intelligent control: touch screen centralized operation, visualization of the entire process parameters of the corn cob production line, one click start stop, fault alarm, data recording; Automatic closed-loop control of temperature, speed, pressure, and feeding amount, eliminating the need for frequent manual adjustment. Novices can operate independently after 1-2 days of training, reducing manual dependence and minimizing operational errors.
Sanitary and easy to clean: The whole machine is designed with no gaps or dead corners, and the pipes, rollers, and machine barrels can be quickly disassembled. It can be rinsed with water/cleaning agents; Compliant with GMP standards, suitable for food enterprise hygiene audits, reducing cleaning time by 40%.
5.Corn slice production line supporting services: full cycle support, worry free production
Customized solution: Provide one-stop solutions for process design, equipment layout, and civil engineering support based on factory size, raw materials, production capacity, and budget.
Technology and Training: Provide standard formulas (original flavor, sweet flavor, corn and miscellaneous grains) to support the development of functional products; Engineers come to the site for installation and debugging, on-site training for operation, maintenance, and formula adjustment to ensure smooth production.
