Embodiment

[0048] The first step, raw material screening treatment: select peanut seeds with relatively full particles and no mildew or deterioration, clean them, and then pass through a cleaning sieve to remove impurities. The cleaning sieve is a 10-mesh screen, and the magnetic separator carefully cleans;

[0049] The second step, pressing embryos: shelling and peeling the oil seeds, crushing, using microwave wall breaking technology to irradiate the crushed peanut seeds, using microwave irradiation for 25s, microwave intensity is medium to high-grade, and then Soften, soften for 30 minutes, the discharge temperature is 60°C, the moisture content in the embryo is 9% when discharging, and then put it into the embryo squeezer to squeeze the embryo. Embryo slice thickness is 7mm;

[0050] The third step, steaming and frying: put the germ slices into the steamer, steam for 10 minutes at a temperature of 102°C, and roast after steaming, send the steamed embryo slices into the frying pan to ...

Abstract

The invention discloses an improved freshness retaining squeezing method. The improved freshness retaining squeezing method comprises raw material screening, embryonic squeezing, cooking, squeezing, filtering and postprocessing, and specifically comprises the following steps that firstly, raw material screening is conducted; secondly, embryonic squeezing is conducted, wherein oilseeds are husked, broken, softened and squeezed into embryonic sheets; thirdly, cooking is conducted, wherein the embryonic sheets are steamed and then baked; fourthly, squeezing is conducted, wherein the embryonic sheets are added into an oil press, crude oil is squeezed out, crude oil precipitates, and impurities are removed; fifthly, filtering is conducted, wherein fine filtering, low-temperature anhydrous dephosphorizing and centrifugal treating are carried out, and oil liquid on the upper layer is taken; sixthly, postprocessing is conducted, wherein aflatoxin is removed, nitrogen charging freshness retaining is conducted, and constant-temperature storing is conducted. According to the improved freshness retaining squeezing method, a pure kernel physical squeezing oil making method is adopted, nutrition in the oil material can be completely retained in finished grease, no chemical solvent is adopted in the whole production process, the problem that oil is polluted chemically is avoided, and the natural green, nutrition, health, aromatic flavor of the finished oil are ensured; nitrogen charging freshness retaining is adopted, storage and transportation are facilitated, and oxidation is prevented.

Description

【Technical field】 [0001] The invention relates to the technical field of oil product pressing, in particular to the technical field of improving a fresh-keeping pressing method. 【Background technique】 [0002] Existing large and medium-sized oil companies mainly use pressing and leaching processes in oil production. The crude oil with more impurities is first obtained, and then refined to obtain edible refined oil. [0003] The processing technology of pressed oil is "physical pressing method", while the processing technology of leached oil is "chemical leaching method". The leaching method adopts the organic solvent extraction method. The oil is extracted after fully combining the organic solvent of the oil, and then the mixed oil composed of the solvent and the fat is separated, and the solvent is recovered to obtain crude oil. Therefore, it is difficult to completely remove organic substances such as normal ethane that are harmful to the human body. Only after refining ...
