Description

Technical Field

[0001] This utility model relates to the field of filtration devices, and in particular to a filtration device for impurities in lard residue liquid. Background Technology

[0002] Lard has a long history in Chinese cuisine. As early as the Northern and Southern Dynasties, Jia Sixie recorded the method of rendering lard in detail in his book "Qimin Yaoshu". To this day, lard remains one of the important ingredients in Chinese cuisine, adding a unique taste and aroma to various delicacies.

[0003] High-quality pork fat or pork back fat is the foundation for rendering good lard. Pork back fat is mainly a piece of fat from the pig's belly, located in the abdominal cavity close to the ribs. It has a high oil yield, resulting in better quality lard. Cut the selected pork back fat or pork fat into small pieces or strips and simmer over medium-low heat. As the water gradually evaporates, the pork back fat begins to release its oil. After the lard is rendered, it needs to be cleaned of solid impurities to improve its purity and taste. Traditional filtration methods, such as manual filtration using filter paper or gauze, are inefficient and time-consuming. For large-scale lard refining enterprises, manual filtration may not meet production needs.

[0004] Therefore, to address the problem that the traditional methods for filtering impurities in lard residue cannot meet the production needs of large quantities of lard, a lard residue impurity filtration device can be designed. Utility Model Content

[0005] To overcome the problem that traditional methods of filtering lard residue and impurities cannot meet the production needs of large quantities of lard.

[0006] The technical solution of this utility model is as follows: a lard residue filtration device, comprising an oil refining tank, a tank cover, a rotating motor, stirring blades, an oil extraction assembly, and a lard residue impurity collection frame; the upper end of the oil refining tank is provided with a split-design tank cover; a rotating motor is installed at the center of the lower end of the oil refining tank; stirring blades are installed on the outer side of the output shaft of the rotating motor to stir and prevent scorching during lard heating; an oil extraction assembly is installed on the inner side of the tank cover to convey the liquefied lard upwards; the oil extraction assembly includes an outer tube; a drive motor is installed at the upper end of the outer tube; a spiral blade located on the inner side of the outer tube is installed at the lower end of the output shaft of the drive motor; symmetrical oil outlet pipes are connected to the upper outer end of the outer tube; and a lard residue impurity collection frame for filtering lard residue impurities is snapped into place on the inner side of the tank cover.

[0007] Preferably, the first step is to pour the pork fat cut into small pieces or strips into the oil refining tank, put the lid on the oil refining tank, heat up the inside of the oil refining tank, start the rotating motor to make the stirring blades start to rotate, stir the pork fat, ensure that the pork fat is heated evenly to prevent scorching, and the pork fat gradually liquefies.

[0008] The second step is to start the drive motor after the lard has been completely liquefied, so that the spiral blades rotate inside the outer tube to generate suction force and transport the liquefied lard upward to the oil outlet pipe.

[0009] The third step is that the lard flowing out of the oil pipe is caught by the lard residue and impurity collection frame, and the lard residue and impurities are trapped in the filter screen for effective filtration, and the lard liquid falls into the oil refining tank.

[0010] Fourth step: After continuously pumping oil for 10-15 minutes, turn off the oil pumping unit. The impurities in the lard residue liquid will be completely separated.

[0011] Fifth, open the drain pipe at the front to drain the pure lard. Finally, open the lid and remove the lard residue and impurity container from the extended edge of the lid to clean the internal impurities.

[0012] Preferably, the stirring blades adopt an "L" shaped structure; the number of stirring blades is four sets, which are distributed in a ring at equal intervals.

[0013] Preferably, the lard residue impurity collection frame is placed outside the oil extraction assembly; the oil outlet pipe is higher than the lard residue impurity collection frame.

[0014] Preferably, the lower end of the bucket lid is fixedly connected to an extended edge; a positioning groove is provided on the outer side of the extended edge; a positioning plug is fixedly connected to the outer side of the lard residue impurity holding frame; the positioning plug and the positioning groove are matched in position and quantity.

[0015] Preferably, an oil drain pipe with a valve is installed on the lower front side of the oil refining tank; support legs are welded to the outside of the oil refining tank.

[0016] Preferably, a gap is provided between the oil extraction assembly and the stirring blade.

[0017] Preferably, a filter screen is provided on the bottom surface of the container for holding pork lard residue and impurities.

[0018] The beneficial effects of this utility model are:

[0019] This invention uses a rotating motor to drive the stirring blades to continuously stir the lard, ensuring uniform heating during the heating process and effectively preventing the lard from sticking to the bottom. This improves the efficiency and quality of oil refining. The suction force generated by the rotation of the motor and the spiral blades transports the liquefied lard to the outlet pipe. The lard is then effectively filtered through a filter screen in the lard residue and impurity collection frame, trapping impurities and ensuring the purity of the lard. This process requires no manual intervention, greatly improving the automation level of the oil refining process. The entire device adopts a split design, facilitating subsequent cleaning and maintenance. Attached Figure Description
