Following the stable operation of the continuous cold-pressing production line for walnut kernels at the Xinjiang Housheng Wensu Industrial Park, Luoyang Zhaoge Environmental Protection Technology Co., Ltd. has achieved another success – the Yunnan Housheng Biotechnology continuous hydraulic cold-pressing production line, with a daily processing capacity of 45 tons of peeled walnut kernels, built entirely by Zhaoge Environmental Protection, recently completed its overall linkage test and officially commenced operation! This is the second leading-scale and technologically mature continuous cold-pressing production line for peeled walnut kernels in China, marking the standardized replication and efficient implementation of Zhaoge Environmental Protection's technical solutions in this field.

A Turnkey Solution for the Entire Process: Confident in Replicating Success

As the general contractor for both projects, Zhaoge Environmental Protection consistently prioritizes independent research and development, providing a comprehensive turnkey service encompassing design, manufacturing, installation, commissioning, training, maintenance, and after-sales support. From Xinjiang to Yunnan, core technology modules are highly compatible—retaining the fully automated design for walnut kernel conveying, dicing, quantitative feeding, cold pressing, cake production, crushing, cake conveying, and walnut oil filtration and pumping, ensuring the stability and consistency of the production process. Fine-tuning and optimization for different project needs both continues mature experience and considers localized production characteristics, making "replication" not just a simple copy, but a precise adaptation.

High Automation + Low Consumption & Quality Improvement: Significant Advantages of the Production Line

The Yunnan Housheng production line continues and upgrades the core advantages of the Xinjiang project:

Cost Reduction & Efficiency Improvement: With a total installed power of 270KW, only 6-7 people are needed per shift, significantly reducing energy consumption and manpower input compared to traditional production lines, while also reducing the risk of microbial growth from manual contact;

Quality Assurance: The cold-pressing process eliminates the need for filter cloth cake making, fundamentally solving the industry pain point of filter cloth fiber residue affecting walnut powder quality; the entire process temperature is strictly controlled below 55℃, fully preserving the natural characteristics and nutritional value of walnut protein;

Continuous and Stable: The cyclical automated operation mode achieves continuous production from raw materials to finished products, improving overall production efficiency and batch stability.

CHOCOMACH, the Solid-Liquid Separation Expert, Empowers Industrial Upgrading with Technology

From Xinjiang to Yunnan, the two successful implementations not only demonstrate Zhaoge Environmental's technological strength but also highlight its ability to provide standardized and replicable solutions for the nut deep processing industry. In the future, Zhaoge Environmental Protection will continue to be driven by technological innovation to create efficient, energy-saving, and high-quality solid-liquid separation and processing systems for more enterprises.
