Tutorial Guide
Small rapeseed oil processing plants need to be equipped with cleaning, crushing, pressing, refining and other equipment. The global rapeseed oil market is expected to reach US$4.65 billion in 2025 (Statista). Africa's import dependence has exceeded 70% (WTO), and the EU's demand for biodiesel raw materials has increased to 40% (EC data). The return on investment is 20-25% (industry average). It is suitable for seizing the gap in emerging markets.

In the edible oil market, rapeseed oil occupies an important position due to its unique flavor and rich nutrition. For investors who intend to invest in small-scale rapeseed oil production, understanding the required equipment is a key step to open the door to success.

Raw material pretreatment equipment

Cleaning equipment

In order to ensure the quality of the final product, impurities in the raw materials must be removed before processing. The cleaning screen can effectively remove foreign matter such as stones and sand from the rapeseed, preparing for subsequent processes.

Steam cooker

The function of the steam cooker is to adjust the temperature and moisture of rapeseed, so that the oil can be squeezed out of the rapeseed more easily. Common ones include drum electric (coal) frying pans, which can evenly heat the rapeseed to make it reach a suitable state for squeezing. After frying, the rapeseed will not only increase the oil yield, but also improve the aroma and quality of rapeseed oil.

Oil extraction equipment

Oil Press

The oil press is the core equipment of a small rapeseed oil mill plant. It squeezes the oil out of rapeseed through mechanical pressure. Common rapeseed oil presses include single screw oil presses, automatic temperature control oil presses, automatic temperature control vacuum filter integrated oil presses, etc. If the scale of the rapeseed oil processing plant is less than 5 tons per day, or the investment budget is limited, an oil press can meet the basic rapeseed oil processing needs. Different models of oil presses have different processing capacity and performance, and can be selected according to actual production needs.

Filtration equipment

Filter

The crude oil squeezed out by the oil press contains some solid impurities, such as cake residue, suspended particles, etc. The plate and frame filter can filter out these impurities and make the crude oil clear and transparent. It uses the interception effect of the filter cloth to keep the impurities on the filter cloth, and the clean oil flows out through the filter cloth, thereby improving the quality and stability of rapeseed oil.

Refining equipment (optional)

If you want to produce rapeseed oil that meets higher quality standards, refining equipment is essential. It is necessary to configure refining process equipment such as degumming, deacidification, decolorization, and deodorization. The refining process can remove harmful impurities, odors, and pigments in the crude oil, so that the rapeseed oil meets the relevant national edible oil standards. The configuration of small rapeseed oil refining equipment can be customized according to actual needs and production scale.

When investing in a small rapeseed oil mill plant, the key is to configure the equipment properly. From raw material processing to oil pressing, filtering, and even refining, each step requires the support of appropriate equipment. When purchasing equipment, it is recommended to choose a manufacturer with reliable quality and perfect after-sales service to ensure the normal operation of the equipment and the smooth progress of production.
