Customized refinery equipment for edible oil manufacturers Complete refining system

Introduction

This fully customized edible oil refining system is designed to meet the diverse processing needs of farms, small oil mills, and medium-sized edible oil producers. This fully integrated refinery equipment converts crude vegetable oil into high-quality, market-ready edible oil. All oil storage and oil pipes in the refining system are made of food-grade stainless steel and are finely polished. It provides complete fine filtration for crude oil, including degumming and dephosphorization, deacidification, dehydration, and decolorization, ensuring safe and hygienic oil production.

This system is widely used to process a variety of vegetable oils, including:
Peanut oil, rapeseed oil, soybean oil, sunflower oil, flaxseed oil, walnut oil, sesame oil, hemp seed oil, hemp flower oil, pumpkin oil, black cumin oil (black seed oil), nigella sativa oil, cactus seed oil, grapeseed oil, coconut oil, hazelnut oil, peanut oil, almond oil, jajoba seed oil, pomegranate seed oil, castor seed oil, rapeseed oil, melon seed oil, cumin seed oil, apricot kernel oil, mustard seed oil, nettle seed oil, neem seed oil, raspberry oil, pepper seed oil, rosehip seed oil, cocoa bean oil, cocoa nib oil, thistle seed oil, blueberry seed oil, tamanu seed oil, inca inchi oil, coriander oil, fennel seed oil, shea butter, and other hot-pressed and cold-pressed edible oils.

Regardless of the edible vegetable oil being processed, this refinery machine offers customizable configurations tailored to the scale of your business. Customization options include agitated centrifugal degumming tanks, neutralization tanks, decolorization tanks, deodorization tanks, and an optional plate and frame filter press. This complete refining equipment achieves first-class edible oil standards in a single refining step, ensuring smooth market access.

Refinery Machine Workflow:

1. Hydration degumming: This degumming method utilizes the hydrophilic phospholipids present in colloidal impurities. A certain amount of water or electrolytes is added to the crude oil to cause the phospholipids to absorb water, swell, aggregate, and separate. During the degumming process, phospholipids are the primary coagulation and precipitation agents, in addition to proline, mucus, and a small amount of metal ions that can bind to phospholipids.
2. Alkali refining and neutralization deacidification: All unrefined oils and fats contain a certain amount of free fatty acids. The process of removing these free fatty acids from oils and fats is called deacidification. Deacidification methods include alkali refining, distillation, ASE, and esterification.
3. Adsorption decolorization: Oil is decolorized by adsorption using bleaching clay, activated clay, activated carbon, and other materials. 4. High-Temperature Deodorization: Utilizing the oil’s low volatility, steam distillation is performed under high-temperature, high-vacuum conditions to remove unpleasant odors and volatile components.

Functions and Applications:

This refining equipment effectively removes various impurities, including phospholipids, free fatty acids, moisture, and odor-causing substances, from crude oil (which can affect its edible value and storage stability). This process eliminates excessive oil processing, resulting in a clear, stable, high-quality edible oil that meets food industry standards and extends its shelf life.
