An edible oil preservation device

Abstract

The invention discloses an edible oil freshness-keeping device, and belongs to the technical field of edible oil storage. The edible oil freshness-keeping device comprises a container body and a powermechanism used for extruding oil in the container body; an oil filling hole is formed in the upper end of the container body, a sealing plug is arranged in the oil filling hole, the side wall of theupper end of the container body communicates with an oil outlet pipe, a valve is arranged on the oil outlet pipe, and a first movable piston is arranged in the container body; the power mechanism comprises an air storage barrel and an inflator which communicates with the container body, a second movable piston is arranged in the air storage barrel, a first air hole is formed in the upper end of the air storage barrel, an elastic sealing plug is arranged in the first air hole, a fine hole is formed in the elastic sealing plug, and the air outlet end of the inflator is inserted into the fine hole; and a limiting ring is arranged on the inner side wall of the upper end of the container body, and the limiting ring is arranged below the communicating part of the oil outlet pipe and the container body. The cyclic utilization of the inert gas is realized, the manufacturing cost of the freshness-keeping device is reduced, and the breath safety of people in a kitchen is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of edible oil storage, and in particular relates to an edible oil preservation device. Background technique [0002] Edible oil is one of the main sources for the human body to obtain essential fatty acids. It has important physiological functions in the human body and can also impart an indispensable flavor to food. Its quality is directly related to people's health. Home cooking oil is mainly vegetable oil, such as soybean oil, peanut oil, rapeseed oil, corn oil, sunflower oil, etc. These oils are rich in unsaturated fatty acids such as oleic acid and linoleic acid, making them extremely vulnerable to light, Oxidative rancidity occurs due to the action of heat, oxygen, water, microorganisms, metal ions, etc., and oils that are severely oxidized and rancid are harmful to health. The Food Quality and Safety Laboratory has found through experiments that, if 1L bottled sunflower oil is calculated by pouring 3...
