Integrated animal oil extraction and treatment system

Abstract

The invention relates to an integrated animal oil extraction and treatment system which comprises a feeding portion, a driving portion, a refining portion, a heating portion and an oil residue separating system. The refining portion is formed by arranging more than two U-shaped grooves side by side, a wallboard is shared by each two adjacent U-shaped grooves and provided with a via hole, a spiral conveyor is arranged inside each U-shaped groove, the driving portion is connected with the spiral conveyors and drives the same to rotate, and a transferring device is arranged at the tail end of the spiral conveyor in each of other U-shaped grooves with the exception of the U-shaped groove at the tail end; corresponding to the corresponding via hole, and each transferring device comprises more than two turning plates which can rotate along axis where the corresponding spiral conveyor is positioned to move an object in the corresponding U-shaped groove into the adjacent U-shaped groove through the corresponding via hole. The integrated animal fat extraction and treatment system has the advantages of little heat radiation, stability in running and small size.

Description

technical field [0001] The invention relates to the field of industrial oil refining, in particular to a treatment system for integrated harmless treatment of sick and dead animals and extraction of animal fat. Background technique [0002] The frying of animal and vegetable oils is the main project of industrial oil refining. For the refining of this kind of oil, most of them use hot oil frying in the oil refining cylinder to realize the oil refining, and in order to fully extract the oil, generally multi-stage oil refining equipment is used for oil refining. [0003] Most of the refining cylinders of the existing refining equipment use inclined U-shaped grooves as the refining cylinder, and the propulsion shaft is equipped with spiral blades, which are driven by the gearbox to achieve the effect of refining and oil output. The device forms a set of refining system. However, there are many problems in adopting this oil refining system: First, the propulsion shaft must be ...

AI Technical Summary

Problems solved by technology

However, there are many problems in adopting this oil refining system: First, the propulsion shaft must be in an inclined state like the U-shaped pipe, and the oil liquid surface of oil refining is parallel to the horizontal plane, which will result in less contact between the upper spiral blade and the liquid surface, and the lower one. The helical blade has a lot of contact with the page, so a lot of power is needed to realize the propulsion of the lower part, while the upper part causes a lot of waste, and it is also easy to break the shaft; secondly, the gearbox must be inclined at a certain angle like the propulsion shaft, which will As a result, the gears inside the gearbox are oiled unevenly, which is easy to damage the gearbox; again, when using this kind of refining system, the refining units are connected in series in the height direction, which requires a high height space, relatively high requirements for the factory building, and poor adaptability

In the technical solution of the above patent, each oil refining cylinder must be equipped with a corresponding heat preservation device. Although the existing heat preservation measures can play a certain role in heat preservation, all sides of the oil refining cylinder will dissipate heat, and the heat loss is still very large

At the same time, the connection between the above-mentioned multiple oil refining cylinders is connected by connecting pipes. Since the inner wall of the connecting pipes cannot be made very smooth, oil residues will accumulate in the connecting pipes after a long time of use, and cannot be discharged to the next refining cylinder. Affects industrial production, and the extra connecting pipe is a heat dissipation point
