Pressing bar and Pressing ring combined oil press
With the continuous improvement of people's living standards, pressed edible oil is favored by people.In the prior art, the edible oil is usually squeezed by a screw oil press.There are usually two types of screw presses on the market, one is a pressing ring screw press, which generally consists of a base, a frame, a screw shaft, a pressing cage, a pressing bar, press ring, feed hopper , gearbox, etc.Among them, the pressing ring is one of the core components of the oil press.It directly affects the oil quality, oil yield and residual oil rate of the dry cake of the oil press.
The pressing ring is composed of the inner teeth on the inner peripheral wall of the pressing ring main body and the oil outlet groove on one side of the main body.It cooperates with the wall of the pressing chamber and the pressing screw to form a pressing area, and the oil is squeezed out by repeatedly squeezing the oil. and so on,The internal pressure of the oil press often does not meet the needs of one pressing, and the pressing force is not enough during the pressing process. Therefore, it is necessary to repeatedly press the oil pressing raw materials until the oil in the oil pressing raw materials is squeezed out.The pressing ring oil machine in the prior art has low oil output rate, high residual oil rate in the oil cake, low rotation speed, and easy blockage of oil pipelines.The raw material yield of cold pressing is low, the color of the raw material oil for hot pressing is poor, the acid value of oil is high, and the cake material is easy to overflow (running slag), and the waste is serious.
The other is the pressing bar screw oil press.The pressing part of the traditional pressing bar screw oil press usually consists of pressing bar and screw presses，The pressing bar are easy to wear and tear, the service life is short, the oil yield of cold-pressed raw materials is low, the oil quality of hot-pressed raw materials is poor, the oil is turbid, very unclear, and there is a lot of slag.This is the flaw of the pressing bar screw oil press.
Therefore, in the prior art oil press, neither of the two oil presses can effectively meet the needs of various consumer groups.MCRAYONE combines the advantages of existing oil presses and improves the disadvantages.A compound oil press with both pressing bar and pressing ring structure is researched.At present, the pressing bar oil machine on the market is low in oil yield, and the pressing ring oil machine is too low in output.
MCRAYONE adopts a new type of combined oil press structure (pressing bar and pressing ring), which enables the oil press to work at high speed, effectively solves the deficiencies of the above two types of oil presses, and increases the output at the same time.By reducing the pressing resistance at the front of the press and recombining the pressure distribution in the press chamber, the medium temperature pressing can be carried out at high rotational speed, the advancing speed of the raw materials is increased, and the pressing force at the cake outlet is increased.And avoid the phenomenon of high residual oil rate in the oil cake during oil extraction.The spindle speed reaches 80~135 rpm, which is much higher than the original traditional oil press (28~45 rpm), and the output is much higher than that of the traditional oil press.Moreover, the oil yield is 1~3% higher than that of the traditional oil press.
