TECHNICAL FIELD
[0001] The utility model relates to peanut oil squeezing technical field especially relates to a multistage squeezing equipment for peanut oil production and processing. BACKGROUND
[0002] Peanut oil is a kind of high-quality edible vegetable oil extracted from peanuts, and it plays an important role in people's daily life and food industry. As a widely planted oil crop worldwide, peanuts contain rich oil components in their kernels. The oil gives peanut oil a unique flavor and texture. From a nutritional perspective, peanut oil is rich in unsaturated fatty acids such as oleic acid and linoleic acid, which are beneficial to human health and help lower cholesterol and protect the cardiovascular system.
[0003] Due to the structural characteristics and oil distribution of peanuts, multistage squeezing is crucial for peanut oil production. The kernels of peanuts have a complex cell structure, and the oil is distributed within cells, between cells, and in some small oil bodies. Single-stage squeezing cannot completely destroy these structures and release all the oil. Multistage squeezing gradually increases the pressure and changes the squeezing conditions, which can more effectively break the peanut cells and release the oil from different levels and locations. This not only significantly improves the oil yield but also ensures higher quality of the extracted oil.
[0004] The traditional method of peanut squeezing is to pack peanuts with gauze, then use wooden planks to stack and hammer with wooden stakes until oil is extracted. This traditional method not only consumes time but also has low oil yield. With the development of technology, multistage squeezing equipment has emerged. In existing peanut oil multistage squeezing technology, multiple sequential working squeezing chambers are set up to avoid the problem of insufficient oil extraction in single-stage squeezing, achieving relatively high oil yield. However, due to the fixed structure of the squeezing chamber, the internal squeezing components lack flexibility, and the number of squeezings cannot be adaptively adjusted for different varieties, different moisture contents, and different particle sizes of peanut raw materials during the squeezing process, resulting in unstable squeezing effect and large fluctuations in oil yield.
