Cold Press Oil Machine: A Green and Environmentally Friendly Production Technology

Cold pressed oil is produced through a physical pressing process carried out at low temperatures. Unlike conventional fats and oils, cold pressed oil does not require further refining. It only needs filtration to meet edible oil standards, making it a green and environmentally friendly production technology. This method is suitable for processing oilseeds with high oil content and producing high-quality edible oils.

Advantages of Cold Pressed Oil

Compared to other oil extraction methods, cold pressed oil has several significant advantages:

1. Retaining Nutrients:

Cold pressed oil is extracted under low temperature conditions, which maximizes the retention of nutrients in the raw materials, such as vitamin E, polyphenols, and other antioxidants. These nutrients play an important role in human health, promoting the development of the nervous system, bones, and brain, and preventing diseases such as arteriosclerosis, cardiovascular disease, diabetes, and digestive disorders.

2. Rich Taste and Flavor:

Since the extraction process does not involve high temperatures, the taste and flavor of cold pressed oil are more pure. It better retains the unique aroma and taste of the raw materials, such as olive oil and flaxseed oil.

3. Reduced Harmful Substances: 

High temperature extraction can cause chemical reactions that produce harmful substances, such as trans fatty acids. Cold pressed oil, extracted under low temperature conditions, effectively avoids the production of these harmful substances.

4. Longer Shelf Life:

Cold pressed oil has a higher content of nutrients and antioxidants, enhancing its antioxidant capacity. This makes it less prone to oxidation and deterioration during storage, resulting in a longer shelf life.

5. Versatile Cooking Methods: 

Cold pressed oil is suitable for cold dishes, salads, and other low-temperature cooking methods. It can also be used for frying and stir-frying, but it is recommended to minimize cooking time and temperature to maintain its nutrients.

6. Health Benefits: 

Cold pressed oil helps prevent osteoporosis, promotes metabolism, and produces less smoke, reducing the likelihood of health problems.

How to Choose a Cold Press Oil Press Machine

When selecting a cold press oil extraction machine, consider the following aspects:

1. Oil Extraction Technology:

Ensure the oil press uses cold press technology, allowing it to operate in a low temperature environment to retain the nutrients and natural flavor in the oil.

2. Material and Safety: 

The oil press should be made of food-grade stainless steel, such as 304 or 316 grade, to ensure corrosion resistance, ease of cleaning, and safety of the extracted oil.

3. Motor Selection: 

The motor is the core component of the oil press. Choose a motor with moderate power, stable operation, and low noise. For home users, a single-phase motor is sufficient; a three-phase motor is unnecessary.

4. Filtration System:

Consider the accuracy and ease of cleaning of the filtration system. Disc cartridges have high filtration accuracy and are easy to clean but are relatively expensive. Paper cartridges are suitable for many types of oil but require regular replacement. Filter mesh cartridges are less expensive but may have slightly inferior filtration effects.

5. Brand and Reputation: 

Choose a well-known brand with a good reputation to ensure access to quality products and services.

6. Ease of Operation: 

Select an oil press with a simple design and convenient operation for easier oil extraction

To summarize, cold pressed oil has many advantages. When choosing a suitable cold press oil press machine, it is important to consider the oil extraction technology, material safety, motor selection, filtration system, brand reputation, and ease of operation.
