Presser for pressing sesame oil at low temperature

Abstract

The invention discloses a presser for pressing sesame oil at a low temperature, and belongs to the technical field of sesame oil processing. The presser comprises an oil pressing cylinder, a thick supporting leg is arranged on the left side of the bottom end of the oil pressing cylinder, a thin supporting leg is arranged on the right side of the bottom end of the oil pressing cylinder, a screw isarranged in the oil pressing cylinder, the left end of the screw penetrates through the oil pressing cylinder to be connected with a first motor, an oil leakage hole area is arranged at the bottom endof the oil pressing cylinder, and an oil filtering bucket is arranged at the bottom end of the oil pressing cylinder and covers the oil leakage hole area. According to the presser, a circular-arc-shaped cooling pipe is arranged, so that the oil pressing cylinder can be cooled, so that the problem of oil pressing coking of sesame seeds can be effectively solved, a cooling discharging box is arranged, so that the sesame seeds can be cooled to a proper temperature and then enter the oil pressing cylinder for oil pressing, the problem of oil pressing coking is further solved, and therefore the quality of oil products is ensured.

Description

technical field [0001] The invention relates to the technical field of sesame oil processing, in particular to a press for pressing sesame oil at low temperature. Background technique [0002] Sesame is also known as linseed, sesame, and flax. It belongs to the family of Flaxaceae, the genus Sesame, and is an annual herb. Sesame seeds contain glucose, fructose, sucrose, stachyose, raffinose, psyllose and a small amount of other oligosaccharides, accounting for about 14-18% of the whole seed. Sesame seeds are rich in calcium, phosphorus, potassium and iron, and are a good source of minerals. Sesame seeds contain almost no anti-nutritional factors, and its raw seeds and processed products are suitable for human consumption. Sesame oil is known as the "king of oils". [0003] Sesame seeds are mainly used for oil extraction and are commercially called sesame oil (also known as sesame oil, sesame oil). Top grade seasoning. [0004] At present, the high-temperature pressing me...

Problems solved by technology

[0005] However, when this traditional screw oil press is working, the temperature of the press chamber is too high due to the continuous pressing of vegetable oil in the press chamber for a long time. Insufficient water makes the raw material coking, and the general oil outlet temperature is above 200°C, which causes the protein denaturation of vegetable oil to exceed the limit and destroys various vitamins, fatty acids, minerals and trace elements in vegetable oil. Nutrients produce substances that are harmful to the human body and affect the quality of oil products; at the same time, sesame seeds need to go through the process of frying seeds, raising smoke, and blowing clean before oil extraction. However, the process of raising smoke can certainly cool down the fried sesame seeds. However, there is no guarantee that the temperature of the sesame seeds entering the oil press will drop to a lower temperature. If the sesame seeds at too high a temperature enter the oil press, it is more likely to cause coking of the pressed oil.
