Lushan Win Tone Engineering Technology Co., Ltd undertakes the construction of a 50-ton corn dual-production line in Chengde.
Lushan Win Tone Engineering Technology Co., Ltd has successfully undertaken the construction of a dual-product corn processing production line with a daily capacity of 50 tons for Chengde Fenghe Agricultural Development Co., Ltd. As a flagship project that underscores Lushan Win Tone Engineering Technology Co., Ltd’s deep-rooted presence in North China’s corn-producing regions, this project—thanks to its versatile adaptability to dual-product processes, the stability of its intelligent equipment, and its precise service capabilities—has injected new momentum into expanding processing pathways and enhancing the overall added value of Chengde’s corn industry, thereby highlighting the supporting role of China’s grain-processing machinery and equipment in upgrading regionally distinctive agriculture.

Chengde is located in the transition zone between the concentrated, contiguous areas of extreme poverty in the Yanshan and Taihang Mountains, and it is also a major corn-producing region in Hebei Province. Relying on the unique climate of its mountainous and hilly terrain, the corn grown here boasts plump kernels and excellent quality. The annual planting area exceeds 3 million mu, and a solid “cultivation—primary processing” industrial system has been established. In recent years, local authorities have focused on improving the quality and efficiency of the corn industry, vigorously promoting a shift in processing models—from “single-product output” to “multi-value-added production.” There is an urgent need for efficient equipment that is well-suited to local corn characteristics and takes into account the diverse processing requirements of various corn varieties. Leveraging nearly three decades of experience in R&D of corn-processing equipment and extensive service experience in the North China production region, Lushan Win Tone Engineering Technology Co., Ltd was selected through a rigorous bidding process and has tailored a customized dual-production corn processing line solution specifically for Fenghe Agriculture.
This 50-ton-per-day corn dual-production line is a specialized facility developed by Lushan Win Tone Engineering Technology Co., Ltd specifically for the mountainous corn varieties grown in Chengde. It integrates core patented technologies for corn processing and features a fully automated, intelligent control system based on a “one main, two auxiliary” architecture. The line can simultaneously produce both corn grits and corn flour, covering the entire process—from corn cleaning and germ removal to grinding, grading, screening, and recovery of by-products. With just 2–3 operators required for efficient operation, this line reduces labor costs by more than 40% compared to traditional single-line systems and boosts overall production efficiency by a factor of two. Given Chengde corn’s optimal moisture content and high starch content, the production line is equipped with a custom-designed YTS-20 dual-production unit specially developed by Lushan Win Tone Engineering Technology Co., Ltd. This unit ensures a stable grits yield of over 45% and a flour yield of up to 38%. The resulting products exhibit uniform particle size and impurity levels below 0.5%, making them ideal not only for local food consumption but also as high-quality raw materials for feed processing and advanced food manufacturing, thereby realizing the diversified value conversion of raw corn grains.
In terms of process design, the production line fully leverages Chengde’s mountainous climate—characterized by dry conditions and dispersed raw material sources—and adopts an integrated approach featuring “intelligent temperature control + graded screening + energy conservation and environmental protection.” This innovative process effectively addresses challenges such as ensuring the quality and shelf life of stored raw materials and maintaining consistent product quality under a dual-production model. The process not only meets Hebei Province’s standards for green agricultural development but also precisely aligns with the “flexible production” needs of small- and medium-sized processing enterprises. After the project goes into operation, its annual corn-processing capacity will reach 15,000 tons, with projected annual sales revenue exceeding 30 million yuan. The plant will be able to produce 6,750 tons of corn grits and 5,700 tons of corn flour each year. Its products will serve the entire Chengde region as well as neighboring areas such as Tangshan and Qinhuangdao, thus establishing an industrial model characterized by “local harvesting—diversified processing—nearby distribution.” According to the head of Fenghe Agricultural Development Co., Ltd., Lushan Win Tone Engineering Technology Co., Ltd’s customized dual-production solution, reliable equipment quality, and attentive customer service have provided the company with a solid foundation for seizing regional market opportunities and achieving upgrade and transformation.
As a high-tech enterprise integrating engineering design, R&D, manufacturing, and localized services, Lushan Win Tone Engineering Technology Co., Ltd has always taken technological innovation as its core competitive edge. Relying on the Henan Province Corn and Coarse Grain Complete Sets Engineering Technology Research Center, the company holds 32 national patents. Its corn-processing equipment has been widely adopted in production areas across North China and Northeast China, accumulating extensive experience in serving small- and medium-sized capacity projects. For this Chengde project, Lushan Win Tone Engineering Technology Co., Ltd has assembled a dedicated service team to provide comprehensive coordination throughout the entire process—from equipment R&D and manufacturing to on-site installation and commissioning, technical training, and after-sales maintenance. The team has tailored the solution to suit the mountainous terrain and streamlined operational procedures, ensuring that the production line will be fully operational within 60 days and efficiently meeting customers’ actual production needs.

Currently, corn-producing areas in the heart of the Yanshan Mountains are accelerating their transformation toward a processing industry that is “small but refined, diverse yet high-quality,” driving strong demand for flexible and intelligent processing equipment. The successful commissioning of Lushan Win Tone Engineering Technology Co., Ltd’s dual-production corn processing line, with a daily capacity of 50 tons, not only fills the gap in smart equipment for small- and medium-sized corn processing facilities in the Chengde region but also provides an excellent model for the diversified upgrading of the mountainous corn industry in North China. Looking ahead, Lushan Win Tone Engineering Technology Co., Ltd will continue to deepen its expertise in grain-processing equipment, developing more targeted solutions tailored to the specific characteristics and processing needs of different regional production areas. By providing high-quality equipment and services, we will empower local specialty agriculture to enhance quality and efficiency, thus putting into practice our development philosophy of “winning the world with products and reaching the future through service.”
