Special deep-bed filter for squeezing of edible oil

Abstract

The invention discloses a special deep-bed filter for squeezing of edible oil. The special deep-bed filter is prepared by using natural quartz mine as a raw material and carrying out processing like fragmentation, washing and fine screening and has the advantages of no impurity, crush resistance, wear resistance, high mechanical strength, stable chemical performance, strong pollutant intercepting capability, high benefits, a long service cycle and reusability. The filter is of a multi-edge spherical shape and purely white and has the characteristics of high mechanical strength, strong pollutant intercepting capability, good acid resistance, etc. A cylindrical container is filled with a quartz sand filter material; a lower cone is arrangd below and connected with a barrel so as to facilitate collection of filtered edible oil; a bearing annular plate is arranged at the lower part in the container to restrict space filling by the quartz sand filter material; a filter cartridge is arranged to increase a filtering area and guarantee large filtering flow; a quick-opening bolt is arranged above the barrel and connected with an ellipsoidal head; and an oil inlet pipe and a squeezed oil pipe are arranged on the ellipsoidal head. Edible oil is subjected to pollutant interception and impurity adsorption by the quartz sand filter material, so the effect of high efficiency filtering is achieved.

Description

Technical field: [0001] The product involved in the invention is suitable for the technical field of pressing and fine filtering edible oil in the refining process of edible oil. Background technique: [0002] The improvement of the clarity of filtered vegetable oil is a major problem in the production of edible oil factories. The current cooking oil filtration methods mainly include three major categories: sedimentation separation, steel mesh or filter cloth filtration and centrifugal separation. However, the existing clarification technology has disadvantages such as time-consuming, complicated equipment operations and unsatisfactory clarification effect. Sedimentation separation, the separation time is long and the operation process is complicated; steel mesh or filter cloth filtration, the filter layer time is long and is not suitable for the filtration of strong flavor edible oil; the separation effect of centrifugal separation equipment is better, but the price is exp...
