Core Advantages of Hot Pressing Technology: Increasing Oil Yield and Production Efficiency

In the production of sunflower seed oil, hot pressing technology has emerged as a game - changer. It significantly boosts oil yield and production efficiency. Compared to traditional methods, hot pressing can increase the oil extraction rate by up to 15%. For example, in a typical sunflower seed oil production line, traditional cold - pressing methods may extract around 35% of the oil from the seeds, while hot pressing can achieve an extraction rate of 50% or more.

Brief Introduction to the Hot Pressing Principle: The Impact of Heating on Oil Extraction

The principle of hot pressing is based on the physical and chemical changes that occur when sunflower seeds are heated. When the seeds are heated, the cell membranes of the oil - bearing cells are broken down, making it easier for the oil to flow out. At a temperature of around 100 - 120°C, the viscosity of the oil decreases, and the surface tension between the oil and the solid components of the seeds is reduced. This allows for a more efficient separation of the oil from the seeds.

Customer Case Sharing: Production Improvement of an Enterprise after Using a Hot Press Machine

A medium - sized sunflower seed oil production enterprise in Eastern Europe faced challenges with low oil yield and high production costs. After installing a hot - press sunflower seed oil press machine, the company witnessed remarkable improvements. Before using the hot - press machine, the daily production of sunflower seed oil was 5 tons, and the production cost per ton was approximately $1000. After the implementation of the hot - press technology, the daily production increased to 7 tons, a 40% increase. Moreover, the production cost per ton decreased to $800, a 20% reduction. This was mainly due to the higher oil yield and more efficient use of raw materials.

How to Balance Yield and Quality: Temperature Control and Process Optimization Suggestions

While hot pressing can increase the oil yield, it is crucial to balance yield and quality. Temperature control is the key. If the temperature is too high, it may cause the oil to oxidize and produce unpleasant odors and flavors. Industry experts recommend maintaining the temperature between 100 - 120°C. Additionally, process optimization, such as adjusting the pressing time and pressure, can also help achieve a better balance. For example, a shorter pressing time at a slightly higher pressure can sometimes result in a higher - quality oil with a good yield.

Practical Suggestions and Industry Trend Outlook

For sunflower seed oil producers, investing in hot - press technology can be a wise decision to improve efficiency and reduce costs. In the future, the sunflower seed oil industry is expected to see more advanced hot - press machines with better temperature control and process automation. Producers should also focus on research and development to further optimize the hot - pressing process and improve the quality of the oil.
