If you are interested in building a mini or small cooking oil refining factory for starting a edible oil business locally and make big money, a small and cost effective cooking oil refinery plant is what need! This small batch oil refining equipment set is featured of:
It is not only widely used for refining of vegetable oil, but also animal oil. Besides, due to compact and reasonable structure designm, the equipment price is much lower which means the cost recovery time is largely shorted. Land is always a problem when running edible oil refinery plant or starting oil milling business. But there is no need to worry about land matter with this set of batch oil refinery equipment. Only 50m2 is enough for establishing a 1-10ton/day cooking oil processing plant. What's more? It is very easy to master the operating skills after our short time professional training.
Our oil refining equipment unit for small scale production has all the bells and whistles including decreased land usage requirements and investment capital. Due to the small size of the equipment set, it is also easy to install and maintain. There are several types of crude oils you can choose to work with including palm oil (CPO), palm kernel oil (PKO) and other types of vegetable oil such as sunflower oil, fish oil, peanut oil, etc.
You have the opportunity to carefully select which type refining process you want to specialize in. There are three common types of edible oil refining process: batch oil, semi-continuous oil, and continuous oil. Each type of refining process can determine the exact size and detailing process of the refinery plant.
This line of an oil refinery is perfect as a mini or small-scale palm oil mill plant. It requires low investment capital and a smaller occupation of land. You are able to refine almost every type of crude edible oil. The primary refinery process includes three stages which are de-gumming, neutralizing, bleaching, and deodorizing. This process eliminates all the impurities which make the oil inedible.
The refining process also includes making the oil palatable and rancid-resistant if and when it is stored for long periods of time. Batch oil refining holds a capacity of 1TPT to 30TPD.
This line is suitable for medium-scale palm oil refining factory which are efficient in accommodating clients requests. You are able to refine different types of crude oils as well as plant and animal oils. It has a capacity of 10TPD to 50TPD.
This line is specifically for large-scale palm oil refinery. It operates automatically with the refinement of the oils with the utmost efficacy. lts daily capacity stands at over 30TPD.
To separate solid phases (Stearine) and liquid phases (Olein), the refined palm oil should go through fractionation process. It is achieved by thermo-mechanical means.
Neutralizing
The degummed oil from process one is subjected to alkali refining. The free fatty acids present in the oils react with the caustic soda leading to the formation of a soap stock. Through the use of a centrifugal separator, the soap stock is removed by centrifugal separators which use water to wash off the soap.
Bleaching
This is where any coloring pigment present in the oils is removed. Here, the neutralized oil from process two is treated with activated carbonlearth. Vertical pressure leaf filters are then used for the removal of the bleaching agent when all the oil has been passed through.
Deodorizing
As suggested by the process name, this is where odor removal takes place. Every cooking oil has its unique natural smell. During the bleaching and the neutralization processes, unpleasant smells are imparted on the oil. It is therefore necessary to get rid of them. This is where any odiferous material present is removed. This operation is carried out at temperatures which are extremely high. By maintaining a high vacuum and injecting an open stream, the odiferous matter is removed. Through the use of a vacuum system, it is then carried off to the barometric condensers.
Dewaxing
Oils such as corn oil and sunflower oil have waxes in them. When oil with waxes is kept in relatively low temperatures, it gets a hazy appearances which is generally disliked by customers. The removal of waxes is the final step that a cooking oil refining plant takes before bottling and marketing its oil.
