1. Clean up. Into the plant's oil contains some impurities (sand, gravel, iron, etc.), if not carefully cleaning, will accelerate the press internal mechanical wear and tear, lower oil yield, and even cause malfunctions and accidents.

2. Sheller. For shelled oil, then squeeze should peel, this can increase the production capacity and oil yield. Its supporting equipment: Sheller, separating sieve, separating machines.
3. Broken. Some oils can be squeezed into a monolith, but after crushing, flaking and then press, can significantly improve the oil yield. Its supporting equipment: crushers, flaking machines.
4. Steaming and roasting. Steaming and roasting is an important part of improving the rate of oil, commonly used method is to first oil wetting, and then dried by frying pan so the oil reaches into juice moisture and temperature process requirements, its supporting equipment: steaming wok, Broiling pot.
