Overview

The main purpose of industrial primary rendering of animal fats is to extract pure, high-quality oils for non-food applications. The process handles large quantities of crude fat from pigs, cattle, sheep, and other animals, converting them into industrial-grade oils used in products such as soap, biodiesel, lubricants, and animal feed. It involves high-temperature treatment and mechanical separation to ensure efficiency, safety, and compliance with environmental standards.

SunRise Continuous Dry Refining Process

  • Raw material preparation and pretreatment

    Select high-quality chilled or frozen animal fats (chicken, duck, cattle, sheep, pig) ensuring freshness, odor-free and pollution-free; crush materials to uniform particles to increase surface area and improve rendering speed and oil yield.

  • Foreign matter monitoring

    Carry out mechanical metal detection and manual plastic/plasticizer inspection on crushed materials to remove foreign matter.

  • Melting and dehydration

    Render preheated materials in the disc dryer under steam heating; use internal scraper for large heat exchange area and high efficiency; return oil and add base oil to ensure even heating; under vacuum remove moisture and odor molecules via condenser and exhaust equipment.

  • Oil residue separation

    Separate rendered oil residue in separators; large residues enter buffer and oil press for physical pressing into food-grade or feed-grade fats and oil cakes; fine mixture sent to centrifuge for fine separation to obtain finished oil.

  • Refining and filling

    Further refine oil through degumming, deacidification, decolorization, deodorization as needed; package in sealed containers to ensure quality during storage and transport.

High Efficiency

Disc dryer with scraper provides large heat exchange area and high production efficiency.

Vacuum Dehydration

Under negative pressure, moisture and odor molecules are quickly removed to improve oil purity.
