Chili oil is a staple in cuisines worldwide, from Sichuan hot pot to Mexican salsas. Beyond food, chili seed oil is highly valued in the cosmetic and pharmaceutical industries for its rich content of Capsaicin and Vitamin E.
However, many people confuse industrial chili oil extraction with the kitchen method of infusing hot oil with chili flakes. Industrial production requires extracting the natural oils directly from the dried chili seeds and flesh.
So, how do you get pure oil out of a dry chili seed without burning it? The secret lies in the chili oil hydraulic press machine. In this article, we break down the extraction workflow and explain why hydraulic technology is the gold standard for premium chili oil.
Step 1: Raw Material Preparation
You cannot squeeze oil out of fresh, watery peppers. The process starts with Dried Chili.
- Separation: while the flesh contains some oil, the majority of the oil content (about 15-20%) is located in the chili seeds.
- Crushing: the dried chilies or seeds are crushed into a coarse powder or flakes. This breaks the cell walls, making it easier for the oil to flow out.
Step 2: Pre-Treatment (Steam or Roast)
Depending on the desired flavor profile, the crushed chili material might undergo a brief heating process.
- Roasting: enhances the nutty aroma and deepens the color.
- Steaming: adds moisture and heat to soften the fibers, which increases the oil yield during pressing.
Step 3: The Hydraulic Pressing (The Core Step)
This is where the magic happens. Unlike screw presses that use friction and generate high heat (which can scorch the chili and turn the oil dark/black), the Hydraulic oil extraction process uses Cold Pressing.
- Loading: the prepared chili powder or seeds are wrapped in a filter cloth and loaded into the steel barrel of the press.
- Compression: the Chili Oil Hydraulic Press Machine activates. The hydraulic pump drives the piston upwards, applying immense pressure (often up to 60 MPa).
- Extraction: under this static pressure, the oil is forced out through the oil lines on the barrel.
- Result: because the temperature remains low (usually under 60°C), the extracted oil retains its vibrant red color, distinct spicy aroma, and active nutritional components (Capsaicin).
Step 4: Filtration
The crude oil flowing from the press may contain fine chili particles. It is passed through a vacuum filter or a centrifugal filter to ensure the final product is crystal clear and shelf-stable.
Why Hydraulic? The Advantage Over Screw Presses
If you are in the business of high-value chili oil, the hydraulic press is superior to the screw press for three reasons:
- Color and quality control: screw presses generate friction heat (100°C+), which often “burns” the chili oil, turning it dark brown and bitter. Hydraulic presses keep it cold pressed, ensuring a bright, appetizing red color.
- Higher purity: hydraulic pressing creates less sediment. The oil comes out cleaner, requiring less filtration.
- Versatility: this same machine can be used for other high-value seeds like sesame, walnut, and almond, allowing you to diversify your product line.
Why Choose Our Chili Oil Hydraulic Press Machine?
At Taizy, we understand that for chili oil, color is everything. We have designed our chili oil press machine specifically to handle spicy, high-pigment materials.
- Ultra-High Pressure (60 MPa):
Chili seeds are small and hard. Our machine delivers industry-leading pressure to ensure you get the maximum yield from every batch of seeds. - Food-Grade Stainless Steel (SUS304):
Chili oil is acidic and corrosive. Our barrel and oil pan are made of high-quality stainless steel to prevent rust and ensure food safety standards are met. - Automated Operation:
One-button start. The machine automatically maintains pressure and stops when the extraction is complete, making it easy for a single operator to manage. - Dual-Barrel Option:
For higher capacity needs, we offer dual-barrel systems so one barrel can be pressed while the other is being reloaded, doubling your efficiency.
