Properties of soybean oil after pressing
Cold-Pressed Soybean Oil
Cold-pressed oil is considered the healthiest: it has a distinct odor and doesn’t have a long shelf life.
Crude Soybean Oil
Any oil—after pressing or extraction—is filtered; this product is called crude oil.
Unrefined Soybean Oil
Unrefined oil also has a strong odor, a bright color, and a distinct soybean flavor; it often forms a sediment, but all the beneficial substances are preserved.
This oil contains lecithin in quantities that can significantly improve brain function.
Hydrated Soybean Oil
To obtain unrefined oil, it undergoes a hydration process (removal of lecithin): the product’s biological value decreases, but its shelf life increases to 4 months.

Top 5 questions buyers of oil presses ask before making a purchase
Before signing a contract for an oil press, every buyer goes through the same set of concerns: how much does it cost, when will it arrive, is this equipment a ‘pig in a poke’, and is the manufacturer even trustworthy? We’ve compiled the top 5 questions we’re asked most often about BRONTO presses — and honest answers to each of them.
What types of animal feed can BRONTO equipment produce?
The same BRONTO technological platform — a single-screw extruder, belt dryer, vacuum cooler and pellet cooler — allows for the production of feed with completely different purposes, depending on the recipe and various settings. The difference lies not in the equipment itself, but in how it is configured: the extrusion temperature, the degree of pellet expansion, the moisture content of the mixture and the method of adding fats determine whether the line will produce dry dog food, floating pellets for tilapia or complete feed for poultry. Let’s take a look at the types of feed that are actually produced on BRONTO lines.
