Most of the edible oil used in our daily life is the finished peanut oil purchased in the supermarket, in the township, there are also many oil mills to produce freshly pressed oil, you can prepare your own oil to squeeze, you can also buy the materials prepared by the oil mill to extract oil, the same peanut oil, self-pressed peanut oil and the peanut oil bought in the supermarket What is the difference?
First of all, let's first understand the processing methods of these two edible oils, self-pressed peanut oil is usually processed in the oil mill, after steaming, frying, pressing, filtration and other treatments to obtain peanut oil, self-pressed peanut oil has a strong fragrance, consumers participate in the whole process, and it is a very popular production mode in towns and villages.
The peanut oil purchased in the supermarket is produced in batches by the oil mill, and the commonly used process of the oil mill to produce edible oil is pressing and leaching, and the pressing process is the same as the self-pressed peanut oil, which is the use of the oil press to squeeze the raw materials, and extrudes the oil in the oil, but the oil mill has a large output, the quality requirements are high, and the refined oil needs to meet the edible oil standard to be sold, so the type, specification, quantity and oil mill of the equipment required are very different.
The oil extraction production line used in the oil mill is generally composed of cleaning equipment, pretreatment equipment, oil extraction equipment, refining equipment and filling equipment, and the raw material cleaning equipment is mainly used to remove impurities such as stones, sediment and plant fibers in the oilThe pretreatment equipment is to dehull, crush, roll, steam, fry and quench and temper the raw materialsThe oil extraction equipment is the oil press we are familiar with, which is used to squeeze peanut oilRefining equipment is to remove invisible impurities in peanut oil, such as moisture, colloidal impurities, fat-soluble impurities, pigments, harmful substances, etc.;The final filling equipment is the equipment for filling, labeling, coding and packaging of refined edible oil that meets the edible oil standard, and the edible oil at this time is the finished edible oil we buy in the supermarket.
In addition to the processing methods and equipment, the production environment is also very different. Most of the self-pressed oil are family workshops, the production environment is relatively simple, there is no corresponding testing equipment, most of the oils and fats are directly bottled and eaten after being squeezed out, and the self-pressed peanut oil is processed in the oil mill, the environment is relatively simple, and the quality of oil is difficult to be guaranteed, especially the raw materials such as peanut oil, which are easy to be infected with Aspergillus flavus, if not treated by professional equipment, it is difficult to remove aflatoxin, which affects the safety of consumers. The production environment and sanitary conditions of the oil mill are good, there are corresponding production standards, and after the edible oil is squeezed, the crude oil will be refined and removed through refining equipment, so as to remove the factors that affect the quality of the oil and oil and are harmful to the human body, and produce edible oil that meets the requirements of the national standard to ensure food safety.
The difference between self-pressed peanut oil and finished peanut oil mainly lies in the above points, how to choose edible oil or depends on the preferences of consumers to decide, the existence of potential safety hazards in self-pressed oil is an indisputable fact, but self-pressed oil can not be beaten to death with a stick, many farmers still have the demand for self-pressed oil, not to mention that the commercial oil produced by industry is not a problem at all, and now many oil mills have also introduced small refining equipment to refine the oil, and the refined self-pressed oil after passing the inspection is no different from the refined oil produced by the oil plant。
Refining equipment in the oil production process is an important equipment to ensure the quality and grade of oil, oil mills want to produce national standard edible oil need to use refining equipment, refining equipment according to different materials are divided into stainless steel and carbon steel, according to the degree of automation is divided into intermittent, semi-continuous and continuous three, equipment model output according to the needs of the oil mill to customize, oil mill used small refining equipment can also be customized according to the output, if there is a need can be private message or call ** contact us.
