As a commonly used equipment in modern families or small oil mills, oil press can press peanuts, soybeans, rapeseeds and other oil crops to produce natural edible oil. The operation process may seem simple, but you need to follow the steps strictly to ensure the oil production efficiency, oil quality and equipment safety. This article will systematically introduce the operation process of the oil press, to help users efficiently and safely complete the oil pressing operations.
I. Pre-operation Preparation: Ensure the equipment and raw materials in good condition.
Equipment Inspection
Check whether the parts of the oil press are in good condition, especially the screw, press chamber, oil outlet and other key parts.
Make sure that the motor and transmission device are not abnormal, and the belt is in the right tightness.
Clean the residual oil residue or impurities in the press chamber to avoid clogging.
Raw material treatment
Select dry, mold-free oil crops and remove impurities (e.g. stones, soil).
According to the requirements of the equipment, crush the raw materials to the appropriate size (such as peanuts need to be crushed to 3-5mm).
Dry the raw material to 8%-12% moisture content to improve the oil yield.
Preparation of auxiliary tools
Prepare oil catching containers, cleaning tools, protective gloves, etc.
Check whether the heating device (if preheating is needed) is working properly.
Second, the operation steps: the implementation of phases to ensure the smooth flow of processes
Preheating stage
Turn on the heating function of the oil press (some models need to be preheated manually), so that the temperature of the press chamber rises to 80-120 ℃ (the specific temperature is adjusted according to the type of oil).
Pre-heating time is about 10-15 minutes, after the temperature is stabilized, the material can be fed.
Feeding and pressing
Uniform feeding: After starting the equipment, slowly add the raw materials into the feeding port, keep the feeding speed stable to avoid clogging caused by too fast.
Adjust pressure: Adjust the pressure of the press chamber according to the characteristics of the oil material (usually through the regulator on the equipment), peanuts, soybeans and other hard oil materials need higher pressure.
Observation of oil production: When the oil is normally produced, the oil should be clear and transparent, if there is turbidity or foam, it is necessary to check the water content of the raw material or the temperature of the equipment.
Oil discharge and collection
The oil flows into the oil receiving container through the oil outlet, and it is recommended to use a strainer to filter the residue in the virgin oil.
Regularly clean the oil outlet to prevent the accumulation of oil residue affecting the efficiency of oil production.
Maintenance after operation: the key to prolong the life of the equipment.
Shutdown and cleaning
After the oil extraction is finished, turn off the power and disassemble the press chamber after the equipment cools down.
Use special tools to clean the oil residue in the press chamber, avoid using sharp objects to damage the screw.
Check the wear and tear of screws, bearings and other parts, and replace them if necessary.
Lubrication and maintenance
Apply lubricant to the transmission parts and bearings to reduce friction loss.
When out of use for a long time, place the equipment in a dry and ventilated place to prevent rusting.
Safety Precautions
Wear protective gloves during operation to avoid scalding of high temperature parts.
Do not disassemble or repair parts while the equipment is running.
Children should be used under adult supervision.
Common Problems and Solutions
Low oil yield: check whether the water content and temperature of raw materials are up to standard, or adjust the pressure of pressing chamber.
Equipment clogging: stop the machine immediately, reverse rotating screw to clean up the oil residue, or use special dredging tools.
Strange noise or vibration: check whether the screw is bent or the bearing is damaged, and contact the after-sales service in time.
V. Recommendations
The operation of the oil press should follow the complete process of “preheating-feeding-pressing-cleaning” and pay attention to details and safety. Regular maintenance of the equipment and selection of high-quality raw materials is the key to improve the oil production efficiency and oil quality. For novice users, it is recommended to practice with a small amount of raw materials first, and then expand the production scale after familiarizing with the performance of the equipment.
Through scientific operation and careful maintenance, the oil press can not only efficiently produce natural cooking oil, but also become a powerful assistant for healthy family life. We hope that the guidance in this article can help you easily master the skills of oil extraction and enjoy the fun of self-pressing oil!
