Edible vegetable oil filtering device and process

Abstract

The invention provides an edible vegetable oil filtering device and process, belonging to the field of physical filtering of edible vegetable oil. According to the invention, a crushed peanut cake isused for assisting in filtering; a part of flavor substances and grease can be taken away by adding a food filter aid, so the flavor of a filtered oil product is reduced, and the oil yield is decreased; however, due to the fact that the peanut cake contains rich peanut oil flavor substances, the flavor of finished oil can be improved, oil yield is increased, and cost is reduced. A closed connecting pipeline is connected with a suspension separator, and separated oil enters an oil tank and enters subsequent filtration. Air collected at an upper layer is purified, and the purified air returns toan air compressor for recycling. After a process is improved, filtered oil enters a sealed environment, so pollution is avoided, environmental and air pollution caused by lampblack formation in a vehicle blowing process is avoided; and in addition, the oil yield of filtered oil is remarkably increased through cyclic utilization of air.

Description

technical field [0001] The invention belongs to the field of physical filtration of edible vegetable oil, and in particular relates to an edible vegetable oil filtration device and process. Background technique [0002] The physical filtration of vegetable oil used today is difficult to filter due to the high viscosity of the oil and the difficulty in flowing. For the convenience of filtration, filter aids are often added to vegetable oil to facilitate the filtration of grease and impurities, but it is easy to cause pollution caused by the addition of filter aids, and at the same time, the addition of filter aids will take away part of the flavor substances and oils, which will As a result, the flavor of the filtered oil is reduced and the oil yield is reduced. In addition, the separation of the filter aid will also absorb a part of the oil, resulting in a decrease in the oil yield and increasing the cost.
