Interpreting the Basic Parameters of Screw Oil Presses and Key Points for Selection and Use
The screw oil press is a commonly used piece of primary processing machinery for agricultural products in rural areas. It can press oilseeds such as peanuts, rapeseed, soybeans, sesame, and sunflower seeds, and many small oil mills and growers choose it. Models like 6YL-110 belong to a fairly common series of screw oil presses, but many people, when they get the product manual, often do not know where to start when faced with a page of parameters. Today let us talk about what the basic parameters of an oil press represent and how to use this information when selecting and using one.
What basic parameters does an oil press have
First, the model. According to the naming conventions for agricultural machinery products, in the 6YL series, "6" represents the category of agricultural and sideline product processing machinery, "YL" indicates a screw oil press, and the number after it generally refers to the screw diameter. The larger the number, the larger the machine specification and processing capacity usually are. For the exact parameters of a particular machine, the manufacturer's nameplate and manual should still be taken as the standard.
Next, the main performance parameters. Matching power refers to the motor power and determines how much electricity is needed. Before buying, confirm whether your home has a 220V or 380V power supply, so you do not bring it home and find it cannot run. Processing capacity refers to how much oilseed can be processed per hour and is directly related to production efficiency, so it should be chosen according to your daily processing volume. Oil yield and residual oil content in the dry cake reflect the pressing effect. When the same machine presses different oilseeds, the values differ greatly, so only asking about the varieties you commonly press makes the reference meaningful. In addition, there are overall weight and dimensions, which affect transport and placement space. Small courtyard workshops especially need to check these clearly.
How to compare parameters when buying
When buying, do not focus only on a single parameter; look at them comprehensively. Processing capacity should match the scale of your oilseed operation. Buy too large and it sits idle and wastes money; buy too small and customers wait in line for processing. Matching power should correspond to the on-site power supply conditions. The quality of the body material and wearing parts such as the pressing screw and press bars affects service life more than appearance-related parameters. It is best to choose a manufacturer whose parts are easy to buy and whose after-sales service is guaranteed. In addition, in many regions oil presses fall under categories eligible for agricultural machinery purchase subsidies. Subsidy standards and model catalogs vary by region, so before buying, consult the local agricultural machinery authorities clearly and place an order only after confirming a model in the catalog. This can save you money.
Key points for daily use and maintenance
Before use, run the machine without load for a few minutes to warm it up. The moisture content and impurities of the oilseed should be properly controlled; too wet or too dry will affect oil yield and may even clog the pressing chamber. When pressing different oilseeds, pay attention to adjusting the feed speed and cake thickness according to the manual. After each use, clean the pressing chamber, oil outlet, and filtering section while hot to prevent residual oil and residue from solidifying and spoiling, which would affect the next pressing. Regularly check the wear of the pressing screw and press bars, and replace them promptly if wear is severe; otherwise, oil yield will drop noticeably. Lubricate the lubrication points regularly according to the manual, and when the machine is out of use for a long time, clean it well and protect it from rust. Only by understanding the parameters and doing enough maintenance can the oil press produce more oil with fewer problems and help you make the accounts for this primary processing work more cost-effective.
