How Physical Pressing Technology Achieves Additive-Free Food-Grade Oils: A Comprehensive Guide to Full-Process Quality Control

How Does the Physical Pressing Process Achieve Additive - Free Food - Grade Oils? A Detailed Explanation of the Full - Process Quality Control Technology

In today's market, the prevalence of oils with additives has become a pain point for consumers. There is an urgent need for pure, natural, and additive - free oils. The energy - efficient and compact soybean oil press from QIE Group addresses this demand through its advanced physical screw pressing technology.

The physical screw pressing technology is a game - changer in the oil production industry. By precisely controlling the pressure gradient and temperature during the pressing process, it significantly impacts the purity of the oil. For example, maintaining a temperature below 60°C can effectively prevent the degradation of oil nutrients and ensure the natural flavor of the oil. Compared with chemical solvent extraction, physical pressing can retain up to 95% of the original nutrients in the oil, while chemical extraction may lead to a loss of about 30% of these nutrients.

Raw Material Pretreatment

Raw material pretreatment is the first and crucial step in producing high - quality oil. The oilseeds need to be carefully selected, cleaned, and dried. Only oilseeds with a moisture content of 8% - 10% are suitable for pressing, as this moisture range can ensure a high oil yield and good oil quality. QIE Group provides detailed guidance on raw material pretreatment, helping users meet strict quality standards.

Operation and Maintenance of Pressing Equipment

The proper operation and regular maintenance of the pressing equipment are essential for ensuring food safety and stable operation. The oil press should be cleaned thoroughly after every 12 - 15 hours of continuous operation to prevent the accumulation of impurities and microorganisms. QIE Group oil press is designed for easy operation and maintenance, which can significantly reduce the user's workload and maintenance costs.

Oil Storage Conditions

The storage conditions of the oil also play a vital role in maintaining its quality. The oil should be stored in a cool, dark, and dry place at a temperature of 10°C - 15°C. Proper storage can prevent the oxidation and rancidity of the oil, ensuring a shelf life of up to 18 months.

Establishing a Full - Process Quality Management System

QIE Group emphasizes the importance of establishing a full - process quality management system. This system covers every aspect from raw material purchase to oil storage, helping users build a systematic food - grade production standard that meets international food hygiene standards.

The oil press from QIE Group is an ideal choice for small and medium - sized oil mills and rural oil processing operations. It features energy savings of up to 30% compared to traditional oil presses, which can effectively reduce operating costs. Moreover, its high - efficiency design can increase the oil yield by about 10% - 15%, bringing more economic benefits to users. In addition, QIE Group provides comprehensive after - sales support, ensuring that users can operate the equipment smoothly.
