Introduction This machine is suitable for the extraction of vegetable oils from such oil-bearing materials as rape seed, peanuts, sesame seed, etc.(the pressing worms can be replaced as required by the user for the purpose of the extraction of oils from some other oil-bearing materials, such as rice bran oil and the like.) Features 1. All such main parts of this machine as worm shaft, pressing worms, cage and so forth are made of high-grade alloy steel through hardening treatment. As a result, in spite of the conditions of high temperature and abrasion under which they work day and night, hey keep durable for a considerable period. 2. The combine of steaming and roasting is also one of the features of this machine. It can be regulated in accordance with the varied requirements of various oil-bearing materials for the temperatures before pressing so as to get high quality oils. 3.The whole process from feeding steaming, roasting up to the discharge of oil and cake goes on automatically and continuously, so it is easy to operate the machine, which results in the caving of labor. 4. Steam pressure 5-6kg/cm2, pressing worm speed: 8rpm;seed steaming and roasting time: 90min;max. Temperature for seed steaming and roasting:125-128¡ãc.
