Oil Extraction Unit (Edible & Non-Edible): Cold-Press & Solvent Extraction

1. What is this item?

A combined facility for extracting oils from seeds and nuts, offering two technologies:

• Cold-Press Expeller: Mechanical pressing that retains nutrients—ideal for high-value edible oils (sesame, groundnut, sunflower).

• Solvent Extraction Plant: Uses food-grade solvents (hexane) to pull out the last residual oil—common for bulk edible (soybean, mustard) and non-edible oils (castor, karanja, jatropha).

2. How is the Quantity Estimated?

• Cold-Press: Rated by kg of seed per hour (e.g., 50–500 kg/hr).

• Solvent Plant: Rated by tonnes per day (TPD) of seed input (e.g., 1–10 TPD).

• Estimate based on your annual seed availability and target yield (oil-to-cake ratio ~5–15%).

3. What are the Cost Components?

• Cold-Press Unit: Expeller machine, hopper, screw shaft, filter press or decanter, minimal heating.

• Solvent Extraction: Conditioning section (pre-heating), extractor vessel, desolventizer-toaster, solvent recovery column, condenser, storage tanks.

• Utilities: Steam boiler (for conditioning), vacuum pumps, solvent recovery pumps, leak-detection & safety interlocks.

• Ancillary: Floor, civil pad, explosion-proof electricals, solvent handling safety gear.

4. Going Rates & Per Unit Cost

Technology Capacity Capital Cost

Mini Cold-Press 50 kg/hr ₹2–4 Lakh

Industrial Cold-Press 300 kg/hr ₹8–12 Lakh

Small Solvent Plant 1 TPD ₹18–25 Lakh

Medium Solvent Plant 5 TPD ₹70–90 Lakh

Large Solvent Plant 10 TPD ₹1.2–1.5 Cr

• Opex:

o Cold-press electricity + labor: ₹5–7/kilo of seed.

o Solvent plant utilities (steam, power) + solvent losses: ₹15–25/kg of oil.

This dual-tech unit lets you start small with cold-press and scale up to solvent extraction as volumes grow—unlocking both premium edible oils and high-yield non-edible feedstocks.
