What machines do rapeseed oil processing plants need to buy?

Oil extraction equipment

There are two common ones, namely oil press and leaching equipment

The oil press is our most common oil extraction equipment, which squeezes the oil out of the oil by applying external force to the raw material. The crude oil extruded by the oil press is of high quality and retains most of the nutrients and flavor of the rapeseed. The residual oil rate of the cakes after oil extraction is high, the production cost is high, but the investment is small, and it is suitable for small and medium-sized edible oil processing plants.

The leaching equipment for leaching and processing rapeseed oil has high efficiency, large output, low production cost and residual oil in the cake, but the investment in the leaching equipment is large and the quality of crude oil is slightly poor, which is suitable for large manufacturers.

  The energy-saving effect of the oil press equipment is very significant. The same type of equipment saves energy and electricity consumption, and reduces the annual investment in energy consumption. It improves production efficiency in disguise, reduces operating costs, and increases profits.

3. There are more than 20 kinds of oil crops that can be processed, which truly realizes the multi-purpose function of one machine and improves the oil yield, which is 2-3 percentage points higher than the oil yield of other equipment of the same type. With the improvement, the interests of users are naturally guaranteed enough.

leaching equipment

Then there is the oil refining facility. Oil refining equipment is an important equipment that determines the quality of edible oil. The state has a series of regulations on refined oil standards, generally including color, odor, transparency, soap content, insoluble impurities, acid value, peroxide value, solvent residue and other indicators. Among them, acid value, peroxide value and solvent residue are mandatory indicators. Oil refining equipment can remove impurities in crude oil, improve oil quality, and control the index within an appropriate range to meet the requirements of national standards.

 leaching temperature.

The leaching temperature has a great influence on the leaching speed. Increasing the leaching temperature can speed up the diffusion of molecules, increase the thermal motion of molecules and thus increase the leaching speed. However, when the leaching temperature is too high, the amount of vaporized solvent in the extractor will increase, the oil leaching will be difficult, the pressure will increase, the solvent loss will increase, and the quality of non-oil substances in the leached crude oil will increase.

leaching time.

According to the combination form of oil and material, the oil leaching process can be divided into two stages, one is to extract the free oil on the surface of the material embryo, and the other is to extract the bound oil with the internal molecules of the oil not destroyed. The oil factory should ensure that the oil molecules have enough time to diffuse into the solvent, but too long leaching time is not conducive to economic production.

Refining equipment

Refining equipment includes processes such as degumming, deacidification, dehydration, decolorization, and deodorization. Some oils also need to be dewaxed. Refined oils have corresponding improvements in terms of color, quality, grade, food safety, and storage time.

Finally, there is the filling equipment. The refined edible oil is tested in batches, and the qualified edible oil is sent to the filling workshop for filling, sealing, code spraying, and packaging, and can be sent to the main supermarket for sale. Common equipment for edible oil filling production line includes filling machine, capping machine, labeling machine, inkjet printer, stacker, etc.
