Edible oil processing and grading device

Abstract

The invention discloses an edible oil processing and grading device comprising a base seat and an outer sleeve fixedly arranged on a top part of the base seat, an inner surface of the outer sleeve isfixedly connected to a first screening cylinder and a second screening cylinder that are fixedly arranged in an inner cavity of the outer sleeve via connecting rods that are arranged in such a way that a ring shape is formed, a cover plate positioned on a top part of the first screening cylinder is provided with a feeding port, and rotating shafts are arranged in the first screening cylinder and the second screening cylinder; parts, positioned in the first screening cylinder and the second screening cylinder, of the rotating shaft are provided with four scraper plates that are fixedly arrangedat equal intervals in such a way that an annular shape is formed, a base plate of the first screening cylinder is provided with a first filter mesh and a second filter mesh that are symmetrically arranged outside the rotating shaft, the second filter mesh is connected to the feeding port of the second screening cylinder via a first discharge pipe, and a bottom plate of the second screening cylinder is provided with a third filter mesh and a fourth filter mesh that are symmetrically arranged outside of the rotating shaft. The edible oil processing and grading device disclosed in the inventioncan be used for grading and screening nutlets thoroughly, and grading and screening accuracy can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to an edible oil processing and grading device. Background technique [0002] Nowadays, the common processing and refining method of edible oil is to shell and crush the raw materials, and then use the leaching method to prepare crude oil through Soxhlet extraction. The method of Soxhlet extraction to prepare crude oil has high extraction efficiency and low preparation cost. Then it is refined under the condition of vacuum distillation to obtain high-grade edible oil; there are many oilseeds for cooking oil, such as sunflower seeds, cottonseeds, olives, palm seeds, rapeseeds, safflower seeds, sesame, macadamia nuts, Mongolian Congo , cane fruit, watermelon seeds, gourd seeds, buffalo gourd seeds, winter squash seeds, pumpkin seeds, etc., the oilseeds are dehulled and pulverized before Soxhlet extraction, but the crushed nuts can be followed up after size gr...

The vibration and noise generated by grading and sieving are often serious, and the sieving effect is not ideal. Cause damage to the nuts and affect the subsequent extraction process
