Introduction to Energy-saving Scheme for Deep Refining of Rice Bran Oil Based on Heat Energy Recovery Technology

Introduction to the Energy - Saving Solution for Deep Refining of Rice Bran Oil Based on Heat Energy Recovery Technology

This article delves into the fully - automatic deep refining energy - saving solution for rice bran oil developed by Penguin Group, which is based on heat energy recovery technology. The solution covers the entire automated production process from rice bran pretreatment, oil extraction to deep refining.

Rice Bran Pretreatment

In the pretreatment stage, the main concern is to remove impurities and control moisture. Through screening, magnetic separation, and drying temperature - control strategies, the system can effectively purify the rice bran. For example, advanced screening equipment can remove nearly 95% of large - sized impurities, and magnetic separation can eliminate metal impurities. Precise drying temperature control keeps the moisture content of rice bran within a suitable range (8% - 12%, for instance), which is crucial for the stability of subsequent processes.

In a real - world factory case, a company used this pretreatment method, and the quality stability of the subsequent oil extraction process increased by 30%.

Oil Extraction

During the oil extraction phase, improving the solvent recovery rate is a key point. The optimized vacuum negative - pressure and condensation systems play a vital role. The vacuum negative - pressure system can reduce the boiling point of the solvent, making it easier to volatilize and be recovered. The improved condensation system can condense and recover more than 90% of the solvent, which not only saves costs but also reduces environmental pollution.

Deep Refining and Heat Energy Recovery

The most remarkable feature of this solution is the cascade utilization of heat energy in the deep - refining process. High - temperature waste heat generated in one part of the refining process can be recovered and reused in other processes with lower - temperature requirements. For example, the heat from refined oil cooling can be used to pre - heat the incoming crude oil. This cascade utilization can reduce energy consumption by about 40% compared to traditional refining methods. As shown in the energy consumption curve (not shown here for simplicity), the system demonstrates excellent energy - saving performance throughout the entire process.

A factory implementation showed that after adopting this solution, the annual energy cost savings reached up to $500,000, which is a significant reduction for enterprises.

Moreover, the intelligent and continuous operation of the system reduces manual intervention. In a traditional process, the possibility of human error can lead to up to 15% quality fluctuations. However, with this automated system, the quality consistency of rice bran oil has increased significantly, with a decrease in quality fluctuations to less than 5%. This not only improves the overall quality of the product but also helps enterprises meet international quality and environmental protection standards, which is especially suitable for export - oriented edible oil enterprises.

In conclusion, this energy - saving solution for the deep refining of rice bran oil based on heat energy recovery technology provides export - oriented enterprises with a high - efficiency, stable, and environmentally friendly option. It offers a reliable way to achieve energy - saving and sustainable development goals.
