Small screw press range — model LYF-503
LYF-503 Cold & Hot Press Machine 3-6 kg/h
The LYF-503 is a bench-top screw (expeller) oil press for home kitchens, farm households, oil retail counters and small food workshops. It runs on a single-phase supply (110 / 220 V), stands on a normal work bench, and is rated at 3-6 kg/h. Every figure on this page is taken from the current supplier listing.

Machine views
How the LYF-503 is built
The body, hopper and pressing chamber are the parts that decide cleaning time and service life, so they are worth looking at closely before choosing a model.
Operation
How a batch runs on the LYF-503
Dry and clean the seed
Remove stones, husk and metal, then bring the seed to the moisture level the material needs. Wet seed is the most common cause of poor yield and a blocked chamber.
Pre-heat the chamber
Let the barrel reach working temperature before feeding. Pressing into a cold chamber pushes seed through without releasing much oil.
Feed slowly and evenly
Feed at a steady rate rather than filling the hopper and walking away. The screw needs a constant load to build pressure.
Settle and filter the oil
Fresh screw-pressed oil carries fine solids. Let it stand, then decant or filter before bottling.
Clear the chamber before shutdown
Run a little dry seed through at the end of the batch so residue does not harden inside the screw and barrel.
Materials
Oilseeds this size of press is used for
- Commonly listed materials: peanut, sesame, rapeseed, soybean, sunflower seed, walnut, almond, coconut / copra, olive, flaxseed, camellia (tea seed), cocoa bean and palm kernel.
- High-oil seeds such as sesame, peanut and sunflower run most easily on a machine of this size.
- Hard or fibrous materials — palm kernel, copra, cocoa — need correct drying and a slower feed rate.
- Low-oil materials give a low yield on any small screw press, whatever the machine.
Screw presses of this class are sized for household and counter-top production. For continuous commercial tonnage, a hydraulic press or a full production line is the correct route.
