Technical Analysis of Energy-Saving Peanut Oil Refining Equipment: A Comparison of Cold-Pressing and Hot-Pressing Processes and Application Guide

This article provides a detailed analysis of the energy-saving peanut oil refining equipment introduced by Penguin Group. It focuses on the technical characteristics, application advantages, and disadvantages of cold-pressing and hot-pressing processes.

Core Technologies: Cold-Pressing and Hot-Pressing Processes

The cold-pressing process of peanut oil is carried out at a relatively low temperature, usually below 60°C. This process can retain more nutrients in peanuts, such as vitamins and unsaturated fatty acids. For example, the vitamin E content in cold-pressed peanut oil can be up to 80% higher than that in hot-pressed oil. However, the cold-pressing yield is relatively low, typically around 30% - 35%. On the other hand, the hot-pressing process involves heating peanuts before pressing, usually at temperatures between 120°C - 150°C. This can increase the oil yield to 40% - 45%. But it may cause some loss of nutrients.

The Role of Intelligent Control System

Penguin Group's energy-saving peanut oil refining equipment is equipped with an intelligent control system. This system can automatically adjust the production parameters according to the production requirements. It can improve production efficiency by up to 30% compared with traditional equipment. Moreover, it can reduce energy consumption by about 25% and labor costs by 20% through optimizing the production process. For instance, in a large - scale oil refinery in the United States, after using this equipment with the intelligent control system, the production efficiency has been significantly improved, and the operating costs have been effectively controlled.

Refining Process and Environmental Compliance

The refining process of the equipment includes degumming, deacidification, decolorization, and deodorization. It strictly complies with international environmental standards. For example, in terms of wastewater discharge, the amount of pollutants in the wastewater can be reduced to less than 5mg/L, which far meets the EU environmental protection requirements.

Industry Case Analysis

In a medium - sized oil mill in Argentina, after using Penguin Group's energy - saving peanut oil refining equipment, the oil quality has been greatly improved. The oleic acid content in the refined peanut oil has reached 50% - 55%, which is highly recognized in the international market. At the same time, due to the high production efficiency and low energy consumption, the cost of each ton of oil production has been reduced by about 15%, and the profit margin has increased by 20%.

Selection and Upgrade Suggestions for Different - scale Enterprises

For small - scale peanut oil processing enterprises with an annual processing capacity of less than 1000 tons, the cold - pressing equipment with a relatively simple structure and lower investment cost is recommended. Medium - sized enterprises with an annual processing capacity of 1000 - 5000 tons can choose the equipment with both cold - pressing and hot - pressing functions to meet different market demands. Large - scale enterprises with an annual processing capacity of more than 5000 tons can opt for the advanced intelligent equipment with high production efficiency and strong refining capacity. International trade companies can recommend different equipment models to their customers according to the market demand and production capacity of different regions.
