Double helix pre-extruding machine

Double helix pre-extruding machine

The double helix pre-extruding machine is composed of a variable speed transmission box, a cake calibration box, an expanding chamber, a pressing chamber, an expanding spiral, a pressing spiral, a feeding device and a base, etc.After cleaning and tempering, the oil is pressed into the squeezing chamber by feeding spiral, and the oil is crushed and squeezed out under the action of spiral extrusion and shearing. Then, the oil is put into the expanding chamber for expansion and shaping, and the historical tile cake is changed into expanded particles.The machine is suitable for high temperature, suitable temperature, low temperature and other pre-pressing extrusion oil pressing process;It is widely used for pre-pressing and puking soybean, rapeseed, cottonseed, oil sunflower, peanut kernel, corn germ and other plant oils.

Second, performance characteristics

1. The oil pressing screw and the expansion screw are arranged on the same spindle, and the pre-pressing chamber and the expansion chamber are arranged successively, so that the pre-pressing and expansion can be completed in one machine.2, the double helical oil press variable speed gear and two synchronous transmission gear arranged in a gear box, shorten the body length, improve the concentricity and strength of the equipment, so that the life of the equipment increased by more than 1.5 times.3. The two-hole pressing chamber is changed into three holes. The upper and lower spirals of the first two holes form a toothed shape, which increases the crushing capacity and makes it easier for the whole oil to be pre-pressed in large scale.4. A spray nozzle or steam jet is set in the dry section of the double spiral press chamber, which can adjust the temperature of the cake, prevent burning and reduce the residual oil.5. Taking corn germ processing as an example, it can eliminate crushing, rolling embryo, steaming and other processes, reduce equipment investment by 50%, reduce power consumption by 40%, reduce coal consumption by 60%, and reduce the pollution of oil processing to the environment.
