Embodiment

[0010] Embodiment: the process steps of the present invention are: a. material selection, select hickory nuts, and manually break the kernels; The temperature is 100-120°C to obtain steamed and fried products; c. Put the steamed and fried materials into a crusher to crush them; d. Heat the oil press, control the temperature at 150°C, heat for 25-35 minutes, and then put the broken walnut kernels Enter the oil press for oil extraction to produce crude oil; e. Filtration, put the crude oil in a vacuum cylinder, filter with a semi-permeable membrane, use an air pump to extract the air in the vacuum chamber, and use the pressure difference to filter the refined oil semi-permeably membrane to filter out impurities to produce refined oil; f. Keep the refined oil warm and naturally precipitate for 20-30 hours, and then pack the refined oil in cans.

[0011] The walnut oil prepared by the invention has high production efficiency and low energy consumption, no new impurities and harmfu...

Abstract

A squeezing process of walnut oil is carried out by choosing pecan, breaking kernels, putting kernels into pan, frying for 10-20mins at 120-140íÒC, breaking the fried products in breaker, heating oil press at 150-180íÒC for 25-35mins, putting the broken kernels into oil press, squeezing, preparing raw oil, filtering, putting raw oil into vacuum jar, filtering to remove impurities, obtaining refined oil, depositing refined oil for 20-30hrs, and packing into final oil. It achieves high efficiency, less consumption and no harmful by products.

Description

technical field [0001] The invention belongs to the field of vegetable oil extraction, in particular to a walnut oil extraction process. Background technique [0002] Walnut is a high-grade green food. Since ancient times, the health care functions of walnuts have been known and praised by people, and they are known as "longevity fruit" and "longevity fruit". "Compendium of Materia Medica" also believes that it can nourish qi and blood. The nutritious walnut oil blended with walnut oil extracted through scientific processing and other edible vegetable oils can better reflect the nutritional value of walnuts. It has been confirmed by experts in nutritional medicine at home and abroad that walnut oil is rich in up to 90% of various unsaturated acids, such as fatty acids, oleic acid, linoleic acid, etc. Among them, the content of linoleic acid is more than that of ordinary rapeseed oil. 16 to 18 times. Linoleic acid is an essential fatty acid for the human body. If ther...
