• What is mustard oil extraction machine?
  • Mustard oil extraction machine has a high oil extraction rate, various yields, and high-quality mustard oil, with wide application. Mustard seed oil is extracted from mustard seeds often by pressing method. The average oil content of mustard seeds is 38-40 percent.
  • How does a mustard machine work?
  • The mustard seeds are fed into the machines through a cooking kettle. The machines uses a mechanical pressure to crush the seeds and extract oil from them. The oil and oilcake (foots) are then separated using a filter press.
  • Why do mustard seeds need to be roasted before pressing?
  • In hot pressing by a screw oil press machine, mustard seeds need to be dried and roasted before pressing. The purpose is to reduce the moisture of the raw material, increase the activity and fluidity of oil molecules, thereby improving the oil yield, and ensuring the strong fragrance of the oil.
  • What is the difference between hot pressing & cold pressing mustard seeds?
  • From the pretreatment of the raw mustard seeds, there are cold pressing and hot pressing. The hot pressing method has a high oil yield and strong fragrance and is used by more users. In hot pressing by a screw oil press machine, mustard seeds need to be dried and roasted before pressing.
  • How to extract oil from mustard seeds?
  • It uses mechanical pressure and friction to extract oil from the seeds. Mustard seed contain around 40 ¨C 45% oil, which can be extracted using GOYUM Oil Expeller Machines. It can be used to produce high quality mustard oil that is suitable for variety of culinary and medicinal purposes.
  • What are the characteristics of cold pressed mustard oil machine?
  • The oil extracted by the cold pressed mustard oil machine has the characteristics of pure and excellent oil quality and long-lasting fragrance. The hydraulic pressure of the mustard oil extraction machine rises rapidly during the pressing process. The pressure loss is small, the force is uniform, and the mustard oil purity can reach 98.8-99.2%.
