![]() ![]() The solution for cold pressed oil producers: squeeze harder and squeeze longer. Since processors are required to keep the oil as cool as possible throughout cold pressing, the oil has a higher viscosity than in a hot press, making it more difficult to extract. It refers to the rotational force inside a press used to generate pressure on the product to extract oil from the seed. Torque is likely the most crucial consideration for cold pressing equipment. Here are four of the top considerations when purchasing a cold press system: A quality cold press will be efficient, durable, and provide flexible cooling options needed to produce a high-quality, more valuable product for your customers. Cold pressing is a change in process, not necessarily in machinery.

Recovery percentage depends on the amount of oil you start with in the seed. When it comes to efficiency, cold pressing varies widely, especially when processing tough specialty materials like grapeseed, coconut, and coffee bean oils. In a cold press operation, however, steps are taken to remove heat from the process and minimize temperature rise through built-in cooling methods and by controlling the speed the oilseeds flow through the press. This traditional “hot” pressing method results in about 80-90% oil removal from the seed depending on the seed.Ĭold pressing is similar to traditional pressing in that the process involves a mechanical, solvent-free oil extraction. Once in the press, oilseeds generate additional heat from pressure and friction that can exceed 200 degrees F, aiding in oil separation. Typically, traditional pressing methods utilize upstream heat for cooking and drying the seed to allow for more efficient separation of the oil in the press. Traditional pressing uses mechanical force to squeeze the oil out of the seed rather than using chemicals. Solvent extraction is the most efficient of the three methods, resulting in the extraction of up to 97% of the seed’s oil. The mixture is then heated to distill off the solvent from the oil before moving into the RBD (Refined, Bleached, and Deodorized) process. Let’s start with solvent extraction, where processors wash crushed oilseed in a solvent, typically hexane, to recover the fat inside. How is cold pressing different from traditional hot pressing and solvent extraction processing But what exactly does cold pressed mean, and what should processers know about cold pressing equipment to capitalize on this trend? Read on to learn about cold pressing and four considerations for investing in cold press machines. With the right equipment, oil processors can benefit from the growing demand and high-price points of cold pressing. Moreover, perhaps due to increased attention on the potential health benefits of cold-pressed oils, they have the highest price point on the market when compared with solvent-extracted or traditional hot-pressed oils. ![]() This expansion represents a 5.3% growth predicted to take place between 2019 to 2026. According to Bloomberg News, the cold pressed oil market is estimated to reach $36.5 billion by 2026. Cold pressed oils have gained significant traction over the past few years, and the trend is expected to grow.
