1.Technology of the Loop Type Extractor
This model has become a relatively advanced machine of its kind widely used in large and medium sized oil extracting factories at present.
It is driven by tailor-made chain and newly designed in a loop structure, featuring low rotating speed and energy consumption, stable and noise-free performance. Its feeding system adopts auto-control level detector and tester interlinked with the main motor speed to ensure some material deal solvent. The extractor runs with negative pressure inside to lessen solvent leak. The high-density miscellaneous oil is inclined to counter flow graded circulation to facilitate vaporization and energy saving. Lower material level is apt for solvent penetration on the one hand, and on the other the simultaneous turnover of material will enable residual oil rate of oil cake to be reduced.
2.Technology of the Rotocel Extractor
The model is energized by rack gear with the uniquely designed rotor to achieve low rotating speed and power and labor consumption. The machine features stable noise-free performance and low-cost maintenance. Within the feeding system, air lock and speed of main motor can be adjusted automatically as per material input volume to stabilize a consistent level so that the extractor can run with slight negative pressure to have solvent leak decrease. The advanced design of miscellaneous oil counter flow and graded circulation will lessen fresh solvent input and bring down residual oil rate in oil cake; the high-density miscellaneous oil will also reduce vaporization yet save energy input. Higher material level in the extractor will facilitate self- filtering of the miscellaneous oil.
3.Wet Meal Desolventizing and Toasting Technology
Wet meal (also called meal) can be handled with DTDC desolventize er toaster which consists mainly of pre-desolventizing layer, ventilating layer, desolventizing layer, drying layer and cooling layer. The outstanding ventilating disc will have material contact with vapor thoroughly for a better desolventization yet with less vapor use. The outlet for second-time steaming remains low. Both the pre-desolventizing and ventilating layers equipped with a horn-shape opening or auto-discharging opening can hold material at a consistent level; the direct steaming layer adopts auto-control air lock to stably adjust material discharge with good leakproofness. The technology has been awarded with invention patent (with the patent No. ZL201320026786.5). This model features stable performance and high desolventizing efficiency. Oil cake by the machine possesses elegant luster and color yet without clotting. Moisture content of oil cake is adjustable and oil cake produced from the machine can be packed directly.
4.Miscella Vacuum Evaporation Process
The apply of miscella vacuum evaporation process, make full using the waste heat of secondary mixed gas produced by the steamed offline. The steam of the steam jet pump directly into the first evaporator without fresh steam, then reduce the steam consumption. Exchange the heat of the high temperature oil of the stripping tower and the heat of mixed oil of second evaporator, improving the two steam inlet temperature further, so does the improving of energy saving. The temperature during this process is low, light crude, and less precipitation phospholipids. The evaporator and stripping tower are not easy to scale formation, reducing the frequency of maintenance and prolonging the service life of equipment.
5.Tail gas recovery process
The process uses stainless steel pall ring absorber, analytical tower.This Equipment designed for paraffin oil distributor, make paraffin oil distribution more uniform and improve the effect of capture and analysis. The specific surface area of Pall ring filler is large, this filler is high efficiency and convenient cleaning. On the tower body is equipped with a special liquid foam capture device with low paraffin oil consumption.
