Technical Field

[0001] The utility model relates to the technical field of rapeseed oil production, in particular to a low-temperature cold pressing device for rapeseed oil production. Background Technique

[0002] Rapeseed oil is an edible oil extracted from the seeds of rapeseed. The color of rapeseed oil usually presents golden yellow or brownish yellow, with a unique "green smell", and it is one of the cooking oils widely used in China and many regions of the world.

[0003] The low-temperature pressing process of rapeseed oil refers to pressing rapeseed to extract oil in an environment below 60°C. Compared with the traditional hot pressing method, the high-temperature treatment is avoided during the cold pressing process, so that the natural nutrients in the oilseeds can be better retained.

[0004] During the rapeseed oil pressing process, certain solid impurities will be generated, such as oil residues, fiber fragments and other residues. These impurities not only affect the appearance of the oil product, such as transparency and color, but also may affect the stability and taste of the oil. Therefore, it is necessary to filter the pressed rapeseed oil. However, the existing pressing devices lack a filtering structure, and the manual filtering efficiency is relatively low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a low-temperature cold pressing device for rapeseed oil production. By using this device to work, the problem that the impurities generated during the oil pressing process are likely to affect the quality of the oil, and the manual filtering of impurities has a relatively low efficiency is solved.

The rotating rod 41 penetrates through the barrel cover 3, and the bottom of the barrel body 1 is arc-shaped.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-5, the filtering component 5 includes a first stirring blade 51 and a second stirring blade 52 fixedly connected to the outer surface of the rotating rod 41, an arc-shaped filter plate 53 arranged inside the barrel body 1, and an annular connecting seat 54 fixedly connected to the top end of the arc-shaped filter plate 53. A filtering cavity 531 is formed at the top end of the arc-shaped filter plate 53, and a second filtering hole 532 is formed at the bottom end of the arc-shaped filter plate 53. The filtering cavity 531 is communicated with the second filtering hole 532. Both the first stirring blade 51 and the second stirring blade 52 are arranged inside the filtering cavity 531. The motor 4 drives the rotating rod 41 to rotate, and the rotation of the rotating rod 41 drives the first stirring blade 51 and the second stirring blade 52 to rotate. The first stirring blade 51 and the second stirring blade 52 continuously rotate inside the filtering cavity 531, which helps to continuously stir the squeezed oil during the filtering process, making the separation of oil residue and grease more thorough, improving the filtering efficiency and the purity of the oil product, and also facilitating the prevention of the deposition of filtering materials and reducing the risk of blockage.

[0027] A pressing cavity 61 is formed at the top end of the pressing barrel 6, and a first filtering hole 62 is formed at the bottom end of the pressing barrel 6. The pressing cavity 61 is communicated with the first filtering hole 62. A crushing blade 411 is fixedly connected to the outer surface of the rotating rod 41, and the crushing blade 411 is arranged inside the pressing cavity 61. The arc-shaped filter plate 53 is arranged directly below the pressing barrel 6. The crushing blade 411 rotates under the drive of the motor 4, which is convenient for effectively crushing the rapeseed entering the pressing cavity 61 from the feed inlet 31, ensuring that the oil material is crushed evenly and finely. The crushed oil material is discharged through the first filtering hole 62 to the arc-shaped filter plate 53 below.

[0028] A limiting block 32 is fixedly connected to the outer surface of the barrel cover 3, and a connecting block 12 is fixedly connected to the outer surface of the barrel body 1. A limiting groove is formed at the top end of the connecting block 12, and the limiting block 32 is correspondingly arranged with the limiting groove. A locking bolt 321 is threadedly connected between the limiting block 32 and the connecting block 12. Through the docking of the limiting block 32 and the limiting groove, it is convenient to position the barrel cover 3, and the barrel cover 3 and the barrel body 1 are fixed by the locking bolt 321. Removing the locking bolt 321 facilitates the separation of the barrel cover 3 and the barrel body 1.

[0029] A slider 63 is fixedly connected to the outer surface of the pressing barrel 6, and a sliding groove 13 is formed on the inner wall of the barrel body 1. The slider 63 is slidably connected with the sliding groove 13. During the process of the barrel cover 3 moving away from the barrel body 1, the slider 63 slides along the sliding groove 13, so as to facilitate the removal of the pressing barrel 6 along the sliding groove 13, reducing the maintenance difficulty of the pressing barrel 6.

[0030] A handle 541 is fixedly connected to the outer surface of the annular connecting seat 54, and a sliding opening 14 is formed on the inner wall of the barrel body 1. The handle 541 is slidably connected with the sliding opening 14 and the handle 541 passes through the sliding opening 14. Sliding the handle 541 out along the sliding opening 14 facilitates the removal of the annular connecting seat 54, thus facilitating the cleaning of the oil residue in the filtering cavity 531.

[0031] A drain pipe 2 is fixedly connected to the bottom end of the barrel body 1, and a valve 21 is fixedly connected to the outer surface of the drain pipe 2. Opening the valve 21 facilitates the discharge of the filtered rapeseed oil. The setting of the valve 21 facilitates controlling the outflow speed and outflow volume of the rapeseed oil.

[0032] During use, rapeseeds are poured into the feeding port 31. The rapeseeds enter the pressing chamber 61 through the feeding port 31. The crushing blade 411 rotates driven by the motor 4 to crush the rapeseeds in the pressing chamber 61. The crushed oil material is discharged into the filtering chamber 531 through the first filtering holes 62. By driving the first stirring blade 51 and the second stirring blade 52 to rotate through the motor 4, the first stirring blade 51 and the second stirring blade 52 continuously rotate inside the filtering chamber 531, which helps to continuously stir the pressed oil material during the filtering process, making the separation of oil residue and grease more thorough, improving the filtering efficiency and the purity of the oil product. It also facilitates preventing the deposition of filtering materials and reducing the risk of blockage. Opening the valve 21 facilitates the discharge of the filtered rapeseed oil. The setting of the valve 21 facilitates controlling the outflow speed and outflow volume of the rapeseed oil. Removing the locking bolts 321 facilitates separating the barrel cover 3 from the barrel body 1, thereby facilitating the removal of the pressing barrel 6 and the annular connecting seat 54.
