Which Is Better, Hydraulic Oil Press Or Screw Oil Press?
Time:Thu-11-21 hits:
Screw oil press is currently the most used oil press in oil plants. But hydraulic oil presses also belong to the more popular types of oil presses. Today we compared two oil presses.
Screw oil presses and hydraulic oil presses are different in terms of squeezing raw materials, and the applicable oils are also different.
The rotary press is suitable for pressing soybean, peanut, rapeseed, sunflower seed, flax, hemp seed, cotton seed, etc.
For high-end raw materials with higher prices and relatively small amounts, hydraulic oil presses are used. Such as squeezing walnut, sesame, almond, pine nuts, these raw materials should be selected hydraulic oil press.
| Screw oil press | Hydraulic oil press | |
| structure | Squeezing cages, racks, hoppers, mixers, cake outlets, electrical cabinets, vacuum pumps, etc. | Hydraulic pump stations, control valves, motors, electrical cabinets, oil cylinders, barrels, racks, etc. |
| working principle | Friction and squeeze between the screw shaft and the oil make the oil and grease flow out | Use liquid as pressure transmission medium to squeeze oil |
| Oil extraction process | Hot and cold double pressing | Hot pressing and cold pressing yield very low oil rate |
| Crude oil | Peanuts, rapeseed, sesame, soybean, olive, corn, kenaf | Peanuts, sesame, rapeseed |
| Yield | Large, 1000kg-4000kg, suitable for medium and small oil mills and oil plants | Small, 500kg-1000kg, suitable for small users |
| Feeding method | Gradually cut | Feed in order |
| Oil delivery method | Flow out from the sliver gap to the oil pan | Flow out from the gap in the oil drum |
| Maintenance method | Cage disassembly | Disassembly and assembly of the whole machine |
| Oil yield | High oil yield | Low oil yield |
| Price | 2W-4W | 1W-3W |
