●Today, we will discuss the practical techniques for cold-pressing and hot-pressing soybean oil. For cold-pressing soybeans, no pre-treatment of the raw materials is required, and the process is relatively straightforward. Typically, pressing the beans twice achieves the desired oil yield. Of course, if you have particularly high requirements—such as pursuing a very high oil extraction […]
●Today, let’s talk about three methods of oil extraction: cold pressing, hot pressing, and medium-temperature pressing, and explain each clearly. Cold pressing is the most straightforward. The oilseed does not undergo preheating treatment and is placed directly into the oil press. Repeating the pressing two to three times usually extracts the oil completely. Hot pressing,
●Many people struggle with deciding whether a filter cloth oil filter or a centrifugal oil filter is the better choice. Today, we’ll break it down. Filter cloth oil filters—whether single-layer, multi-layer, plate and frame, pneumatic, or vacuum types—all use filter cloth to trap impurities in crude oil. If you’re filtering cold-pressed oil, or if the

●During the hot-pressing oil extraction process, if the oil material temperature is too high or the oil press operates under unstable pressure, the cellular structure of the oil material can be damaged. This often leads to an increase in phospholipid content in the crude oil. The step of hydration, phosphorus, and gum removal is specifically
●Current manufacturing technology for oil presses is quite mature. In terms of oil yield, there is no significant difference between round-bar and strip-bar oil presses. However, if a comparison must be made, the strip-bar oil press is simpler to operate, easier to repair, and more convenient to maintain in the long run. Additionally, the press

●Let me introduce the small-scale edible oil refining unit – a compact system designed to enhance the quality of crude oil.This equipment is used to refine raw oils, such as peanut oil, rapeseed oil, tea seed oil, soybean oil, sunflower seed oil, flaxseed oil, and other crude vegetable oils. It effectively removes impurities and undesirable
●Hey everyone, are you confused about the processing steps of hot-pressed edible oil? Is dephosphorization, hydration, and dehydration a must-have or just a redundant step? Today, we’re spelling it all out—no fluff, just practical, actionable info.First, the key takeaway: Whether you need to dephosphorize depends entirely on the roasting temperature of your raw materials. For

●Recently, we’ve received many questions from newbies: I’m starting an oil mill for the first time—how do I pick an oil press? Hydraulic or screw? Truth be told, there’s no one-size-fits-all machine; the best choice depends on your specific needs.For new buyers, the first factor to weigh is: what raw materials will you be pressing?

●So, you’re thinking about the basic equipment needed to set up a small-scale oil press workshop?we’ll walk you through the essential setup.First, you’ll need an oil press machine. This unit comes equipped with an integrated vacuum oil filtration system.Next, you’ll want a feeding machine—an automatic feeder for raw materials—along with a cake recycling system (the

●A friend asked me: “How does a centrifugal oil filter separate impurities from oil?” First, the motor drives the drum to rotate at high speed, causing the oil and impurities inside to move in circular motion along with it. Due to their differing densities, under the action of centrifugal force, heavier impurities—such as oil residue
