Huatai Group Secures National Patent for Subcritical Low-Temp Extraction Flexible Processing System

Recently, the subcritical low-temperature extraction modular integrated processing equipment, independently developed by Henan Huatai Cereals And Oils Machinery Co., Ltd. – a subsidiary of Huatai Intelligent Equipment Group – has been granted national patent certification (Patent No.: ZL 2024 1962374.7). This technological achievement not only demonstrates the company's R&D capabilities but also offers a promising new solution for edible vegetable oil extraction.

Currently, edible vegetable oil extraction in China predominantly relies on n-hexane, with limited adoption of supercritical extraction due to prohibitive investment and operational costs hindering large-scale production. The subcritical low-temperature extraction system distinguishes itself through its "extraction at room temperature and low-temperature desolventization" capabilities. This process preserves bioactive compounds and plant proteins within oilseeds during extraction, creating new pathways for premium oil production and plant protein utilization. Additionally, the equipment significantly reduces steam consumption, effectively lowering production costs while minimizing emissions of waste gas, wastewater, and industrial residue ("three wastes"), aligning with green development principles.

As a certified National Green Factory, National Specialized, Sophisticated, Distinctive, and Innovative Enterprise (Little Giant), and a New Third Board (NEEQ) listed company, Huatai Cereals And Oils Machinery consistently adheres to an "innovation-driven development" philosophy, focusing on scientific research and technological breakthroughs. The company maintains a dedicated R&D team exceeding 100 professionals, with annual investment surpassing RMB 10 million. It fosters strategic collaborations with leading institutions including Jiangnan University, Henan University of Technology, and Wuhan Polytechnic University for joint technology development and talent cultivation. Furthermore, Huatai Intelligent Equipment Group operates technology R&D centers in Zhengzhou, Shanghai, and other locations, and has established a Joint Innovation Center with the Central Plains Food Laboratory to accelerate the commercialization of research outcomes.

Huatai Intelligent Equipment Group maintains a steadfast commitment to technological innovation. The successful development of this subcritical extraction system exemplifies the persistent efforts of the Group's R&D team. Moving forward, the Group will intensify R&D investments to explore novel technologies and processes, contributing to the advancement of the global edible oil production industry.
