For Soybean oil press workshop, there are two kinds of oil pressing: cold pressing and hot pressing. The cold pressing and hot pressing oil rate is higher, the efficiency is higher. The operation is convenient, so it becomes the most popular press method. Then the heat pressing is how to operate it. Soybean oil press equipment as an example.
The first is to screen for screening soybean oil complex, the impurity content is less than 0.1%, and then enter the broken, broken degree of 2 – 4 petals, then softening, reduce the water content of soybean in about 15%, softening time 40 to 50 minutes, and then use the rolling rolling embryo, embryo has two points: one is the destruction of the oil cells easily flow out from the cell, two is rolled granular oilseeds into thin slices, the surface area increases, increased the oil area, but also greatly reduce the oil left blank distance; into the cooker of steaming and frying, steaming and frying soybean moisture in the 1.5 – 2.8% range, the temperature to 100 a 110 degrees that can begin to enter the press for pressing. The thick of cake under the control of the L – 1.5 mm.
Removal of impurity in crude soybean oil
There are a lot of impurities in crude soybean oil, it can generally be divided into two kinds of harmful and beneficial. The main purpose of soybean oil refining is obtained with different procedures and to ensure that people living in different demand and food safety. Soybean oil refining equipment will not remove impurities and all the impurities in crude oil, but will for the oil refining and storage of harmful substances such as gossypol, mucus, water removal, according to different requirements will be retained for the separation of impurities, oil refining useful material, after continuous refining process can be made suitable for the needs of different groups of high quality soybean oil. So oil refining in the production process is a very important procedure.
We are specializing in the production of large oil refining equipment, engaged in oil machinery and complete sets of oil equipment research and development, manufacturing, technical services as one of the modern enterprise, strong technical force, advanced equipment, complete testing means, absorbing foreign advanced technology, production of various specifications of oil refining equipment, applicable to all kinds of oil crops, prepressing, leaching, refining with reliable product quality, high oil yield, low loss, large, small and ideal product factory.
