As a common edible oil in our lives, peanut oil is the choice of many consumers. In addition to being rich in nutrition, its rich flavor is also one of the popular factors. Hot pressing is a common process used by peanut oil mills to produce peanut oil. The peanut raw materials are subjected to high-temperature heat treatment before peanut oil pressing. The temperature and moisture of the oil are controlled by high-temperature frying. The reaction will occur during the frying process, increasing the aroma of the oil. Peanut oil produced by hot pressing has a high oil yield and a strong aroma.
Hot pressing is commonly used in small and medium-sized edible oil processing plants. The pressing process has a high oil yield and good flavor, but the oil yield is relatively low. Peanut oil pressing cannot fully extract the oil, and the residual oil in the cake is high. For large edible oil processing plants, the high residual oil in the cake will not only affect the oil yield, but also the quality of the cake. Although the edible oil extraction process can obtain a higher oil yield, consumers are more resistant to chemical extraction. In order to achieve the ideal production effect and obtain high-quality peanut oil, it is recommended that large edible oil processing plants use the pre-pressing-extraction oil production process to produce peanut oil.
The pre-pressing-extraction process is a combination of pressing and extraction. First, the peanut raw material is pressed to obtain most of the oil, and then the peanut cake is extracted by the peanut oil extraction equipment. The oil in the cake is dissolved by solvent to form a mixed oil, and then the solvent is separated and recovered by high-temperature evaporation, stripping, condensation and other processes to obtain extracted peanut oil.
The advantages of the pre-pressing-extraction process are large processing capacity, high production efficiency, high oil yield, and can make full use of oil resources to obtain high-quality crude oil and high oil yield. The residual oil in the cake can be controlled within 1%. The crude oil is then refined and processed to obtain healthy peanut oil that meets the quality standards of edible oil. The edible oil mill can also make full use of oil resources to achieve the ideal production goal.
The groundnut oil mill produces peanut oil, and the choice of equipment has a direct impact on the quality and oil yield of the finished oil.
