• 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.
  • 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.
  • What is mustard oil used for?
  • Mustard oil is commonly used in India, Pakistan, Bangladesh, and Nepal as a cooking or flavoring oil. The mustard oil extraction machine has a high oil extraction rate, and large yields and the mustard oil pressed has good oil quality. As a professional cooking oil machine manufacturer, we produce various types of mustard seed oil machines.
  • 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%.
  • What is a mustard oil expeller?
  • The pressing chamber of the mustard oil expeller heats up quickly, so the production is efficient with high oil extraction rate. The oil yield is high, reaching from 30kg/h to 1000kg/h or more, and the energy cost is low. For different models, the screw diameter differs. Beautiful appearance, compact structure, and simple installation.
