Refining process based on peony seed oil squeezing process

Abstract

The invention discloses a refining process based on a peony seed oil squeezing process. The refining process comprises the following steps: raising the temperature of peony seed oil to be 60 DEG C while stirring, adding boiling water, dissolving salt into water, and stewing until separation between hydrated oil sediments and oil is qualified when the water temperature is higher than the oil temperature and colloidal particles start gathering; pumping clear crude oil into a pot, uniformly mixing the clear crude oil, uniformly spraying metered alkali liquor into oil, and starting filtering when the oil temperature is reduced to be 60 DEG C; heating the oil to 90 DEG C, adding a liquid-state discoloring adsorbent, enabling the oil to be in contact with the adsorbent for about 30 minutes, then cooling the oil to be 70 DEG C, and removing the discoloring adsorbent to obtain discolored oil. opening a steam valve and a cooling water valve of a steam-saving ejector vacuum pump, absorbing the discolored oil into a deodorization pot by utilizing vacuum, then opening a heat-conducting oil valve, starting direct steam, shutting down a heat-conducting oil temperature-raising system 30 minutes before deodorization so as to pump out deodorized clear oil. By virtue of the process, the oil quality of the finally obtained peony seed oil reaches edible level, and the oil is free from extraneous odor and bright in color and luster, so that the peony seed oil is safe for a consumer to eat and is high in value.

Description

technical field [0001] The invention relates to a process, in particular to a refining process based on the peony seed oil extraction process. Background technique [0002] Oil press refers to a machine that squeezes oil out of oil by means of external mechanical force. Oil press raw materials, that is, oil crops are divided into plant raw materials and animal raw materials according to their types. In the general production process, we mainly use plant raw materials. The plant raw materials are divided into legumes, seed families and hempaceae. Peanuts are bean crops. Peanuts nourish the stomach and prolong life. They are also known as "longevity fruit" among the people, and they are also known as "vegetable meat" and "vegetable meat" like soybeans. The nutritional value of peanuts is higher than that of grains, comparable to some animal foods such as eggs, milk, and meat. It contains a lot of protein, especially the high content of unsaturated fatty acids, and is very su...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned existing problems such as the appearance of oily odor after oil extraction of peony seeds, which cannot satisfy people's use and cause the problem that its value cannot be reflected. A refining process based on the oil extraction process of peony seeds is designed. , this process can make the oil quality of the peony seed oil finally obtained meet the edible standard, with no peculiar smell and bright color, so that consumers can eat it with confidence and high value. Satisfying people's use, causing problems that its value cannot be reflected
