Animal oil and fat refining device capable of effectively controlling peroxide value

Abstract

The invention discloses an animal oil and fat refining device capable of effectively controlling a peroxide value. The animal oil and fat refining device comprises a primary refining device, a vacuum extraction device, a discharged material temporary storage barrel for receiving oil discharged from the vacuum extraction device, and a product barrel communicated with the discharged material temporary storage barrel through an oil inlet pipe; placing in and taking out of an air isolation pad can be easy through a multi-pedaled splicing structure which is formed in the manner that a through hole is formed in the middle of the air isolation pad, and the periphery of the air isolation pad is in contact with the inner wall of a heating tank; meantime, through a corresponding splicing manner, the unchanged whole structure is ensured, and influence on stirring is avoided; through the adoption of the air isolation pad, the whole upper space of the heating tank is shielded, so that effective air separation is realized; after solid oil and fat melts, the air isolation pad keeps floating on liquid oil and fat to continuously guarantee that the oil and fact is not in direct contact with air, so that preliminary oxidation degree is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of animal fat refining, in particular to an animal fat refining device capable of effectively controlling the peroxide value. Background technique [0002] In the field of animal oil refining production and processing, it often includes rough refining and vacuum extraction steps. During high-temperature rough refining, the block of fat is heated in the rough refining device to melt it while auxiliary stirring is performed. The melted liquid oil will enter the vacuum Extraction steps. figure 1 Shown is a schematic structural diagram of a vacuum extraction device in the prior art. Such as figure 1 As shown, the vacuum extraction device of the prior art includes a feed barrel 1 for accepting melted liquid grease, a pre-vacuum extraction mechanism 2 and a vacuum extraction mechanism 3, wherein the pre-vacuum extraction mechanism and the vacuum extraction mechanism are communicated with it The vacuum pump 8 ma...

Problems solved by technology

[0003] However, in the high-temperature rough refining process of oil in the prior art, the oil will inevitably keep in contact with the air when it melts at high temperature, and the oil will be oxidized at high temperature, and the oil production process of the vacuum extraction device is continuous, but the discharge The amount of oil is very small, basically dripping or flowing down in small streams. When entering the temporary storage barrel, the process of flowing down inevitably contacts with air, which increases the degree of oxidation of the oil. At the same time, it enters from the temporary storage barrel When the product barrel is in contact with the air, it will also face the situation of oxidation
