1. Introduction to Cold Press Technology

Cold press extraction uses a heavy-duty mechanical screw to squeeze oil out of seeds like sarson, sesame, almond, and coconut. Since it avoids using high-heat chemical processes, it produces premium "Kachi Ghani" grade oil.

Key Takeaways:

Extracted at temperatures under 50°C to preserve vitamin E and essential fats.
100% chemical-free (no hexane or heavy bleaching agents used).
Produces highly nutritional oil and premium high-protein oil cake (Khal).

2. Step-by-Step Oil Extraction Guide

Seed Cleaning: Use the MMEC Seed Cleaner to remove sand, stones, and dust.
Moisture Adjustment: Ensure seeds have the optimum 6-8% moisture level.
Cold Pressing: Feed seeds into the hopper; the screw extracts oil while discharging dry oil cake.
Filtration: Pass crude oil through the vacuum oil filter to get sparkling clear bottled oil.

3. Comparison Table: Cold Press vs Expeller

4. Pros & Cons of Cold Press Machines

✓ Pros:

Sells at 2x market price as organic oil.
Low electric power usage (suitable for solar).
Extremely safe and silent food-grade SS 304 chambers.

✗ Cons:

Slightly lower yield rate per pass than chemical hot systems.
Requires dry seeds for reliable automatic feeding.

5. Expert Machinery Maintenance Tips

Clean the press screw chamber after every shift. Accumulated oil seeds can dry and harden, increasing motor load upon restart. Check the gearbox oil levels every 3 months for peak efficiency.

6. Frequently Asked Questions

Q: Can I run this machine on a home 220V single-phase connection?

A: Yes, our SP-130 and mini commercial series are specifically designed with single-phase variable frequency drives (VFD) that run perfectly on regular home meters.
