Purchased 112 Drying Kilns at once
112 Drying Kilns Purchased at once by our Rosewood Furniture Client
Niannianhong Group has trusted our drying solutions since 2006, most notably investing in 112 ZQ Series steam – heated conventional wood drying kilns in 2011, a landmark project that transformed their operations. By implementing our precision humidity control systems and custom temperature profiles tailored for high-value mahogany, Niannianhong achieved a 15% to <5% reduction in wood defects.
The collaboration continued to evolve, with our team providing on-site training and predictive maintenance support to ensure peak performance. In 2025, Niannianhong once again chose our advanced hardwood drying kilns for their new state-of-the-art facility, highlighting our ability to deliver scalable, energy-efficient solutions.
Background of Niannianhong Group
Niannianhong Group, founded in 1989 as Yiwu Mahogany Furniture Factory and rebranded as Zhejiang Niannianhong in 1997, is based in Yiwu, Zhejiang. Spanning 620,000 square meters, it’s a major Chinese – style furniture R & D and production base.
It’s a key player in the industry, being a vice – president of the China Furniture Association and a main drafter of Chinese mahogany standards. Its products, like Fudian, Jinding, Yadian, and Gongyi series, made from imported mahogany, have won many awards.
Our First Step Together: A New Beginning in 2006
In 2006, TECH Company partnered with Niannianhong Group. Their repeated orders prove our product quality. Among our steam – heated conventional drying kiln offerings, the ZQ series has emerged as their top – choice product, significantly strengthening our cooperation. The ZQ series is engineered with state – of – the – art technology. It features a double – layer insulation and thermal break design, which not only improves energy efficiency but also ensures stable heat retention during the drying process. This stability is crucial for preventing mahogany from cracking and bending as it dries.
A Rigorous R & D Journey Led by Professors
Facing drying problems like cracking, bending, and internal stress in the mahogany industry, we launched an R & D project led by professors. Focusing on the steam – heated conventional drying kiln ZQ series, we delved into in – depth theoretical research. We analyzed the unique physical and chemical properties of mahogany during the drying process, considering factors such as its density, moisture content, and fiber structure.
Subsequently, we carried out extensive lab – scale and pilot – scale tests. These tests involved simulating various drying conditions, from different initial moisture levels to varying ambient temperatures and humidity. Based on the test results, we optimized the drying parameters for the ZQ series.
The ZQ series is equipped with an advanced intelligent control system. This system allows for precise temperature control within a range of ±0.5°C, humidity control with an accuracy of ±2%, and highly accurate drying rate adjustment. By precisely controlling the rate of moisture evaporation, we effectively prevent rapid moisture loss, thus avoiding cracking. During the drying process, the system ensures uniform heat distribution throughout the kiln, maintaining an even temperature distribution to prevent bending. Additionally, it implements a multi – stage drying program, which gradually reduces the moisture content of the mahogany, gradually releasing internal stress.
Tailoring Success for Your Business
After numerous tests, we developed a mahogany – specific drying process tailored for the ZQ series of the steam – heated conventional drying kiln. Our technical team provided on – site guidance to ensure that Niannianhong Group’s employees could operate the equipment proficiently.
The ZQ series, with its unique drying process, offers remarkable efficiency. It can complete the drying process 30% faster than traditional drying methods, significantly reducing production time. At the same time, it effectively prevents defects such as cracking and bending. This high – quality drying result has been instrumental in helping Niannianhong Group produce high – quality products and achieve greater profitability. Many of the mahogany furniture pieces produced by Niannianhong Group using the ZQ series have won acclaim in the market for their excellent quality and stability.
A Big Step Forward: The 2011 Purchase – 112 Conventional Dry Kilns (ZQ) Purchased
In 2011, Niannianhong Group made a one – time purchase of 112 sets of our ZQ series steam – heated conventional drying kilns. This large – scale procurement is a clear indication of the series’ reliability in solving cracking and bending problems.
The ZQ series has revolutionized the drying process for Niannianhong Group. Before using the ZQ series, the defect rate of their mahogany products due to improper drying was around 15%. After adopting the ZQ series, this defect rate has been reduced to less than 5%. Our cooperation, centered around this series, has led to the creation of numerous high – quality mahogany products, contributing significantly to the growth of the industry.
