Description

Technical Field

[0001] This utility model relates to the field of edible oil production technology, specifically to an edible oil cold pressing device that improves oil yield. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, the requirements for the quality of edible oils are becoming increasingly higher. Cold-pressed oils, processed at low temperatures, retain the maximum amount of nutrients in the oil, such as vitamin E, sterols, and squalene, as well as the flavor of the oilseeds themselves, meeting people's pursuit of healthy and natural foods. Therefore, the market demand for cold-pressed edible oils is constantly increasing, prompting enterprises and researchers to dedicate themselves to developing cold-pressing equipment that can improve oil yield to meet market demand.

[0003] Traditional cold-pressing equipment has a relatively simple structure and working principle. It usually adopts a single spiral extrusion or static extrusion method. During the pressing process, the contact and interaction between the oilseed and the pressing components are not sufficient, resulting in a long pressing time and a low oil yield. Utility Model Content

[0004] In order to solve the technical problems of traditional cold pressing devices that use a single spiral extrusion or static extrusion, resulting in long pressing time and low oil yield, this utility model provides an edible oil cold pressing device that improves oil yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold pressing device for edible oil to improve oil yield, comprising: a mandrel, the mandrel being rotatably connected to the side wall of a horizontally arranged feeding cylinder, the feeding cylinder having a feeding port at its upper part, a pressing cage being a horizontally arranged conical container with gaps, the feeding cylinder being concentrically connected to the wide end of the pressing cage, the narrow end of the pressing cage being concentrically connected to a dispersing cylinder, the dispersing cylinder being concentrically connected to the wide end of the next pressing cage, the pressing cage and the dispersing cylinder being alternately connected, a conical block being connected to the mandrel inside the pressing cage, a spiral blade with a gradually decreasing pitch being connected to the conical block, the spiral blade contacting the inner wall of the pressing cage, and dispersing blades being connected to the mandrel inside the feeding cylinder and the dispersing cylinder, the dispersing blades being formed by multiple incomplete spiral blades arranged spirally.

[0006] Preferably, the diameter of the narrow end of the press cage gradually decreases along the oil conveying direction, and the gap between the inner wall of the press cage and the cone block gradually decreases along the oil conveying direction.

[0007] Preferably, the press cage includes press bars, with multiple press bars evenly distributed around the circumference and connected at both ends to two fixing rings, which are located at the wide end and narrow end of the press cage, respectively.

[0008] Preferably, a guide tube is fastened to the outside of the pressing cage and the dispersing cylinder. The guide tube is connected to the outer surface of the dispersing cylinder and is fixed by a bracket. An oil outlet is opened at the bottom of the guide tube.

[0009] Preferably, the interior of the dispersed cylinder wall is connected to the water cooling circulation system.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The oil is pressed by the spiral blades with gradually decreasing pitch in conjunction with the pressing cage. After the initial pressing, the oilseeds enter the dispersing cylinder. Under the action of the dispersing blades, the oilseeds are dispersed and transported to the next pressing cage. This dispersing and pressing is repeated many times to complete the oil pressing. Dispersing the oilseeds can break down the structure of the oilseeds, exposing the parts that were not fully squeezed, so that more oil can be squeezed out in the subsequent pressing, thus increasing the oil yield.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to a connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-4This embodiment describes a cold pressing device for improving oil yield, comprising: a spindle 1, which is rotatably connected to the side wall of a horizontally arranged feeding cylinder 2; a feeding port 3 is provided at the upper part of the feeding cylinder 2; a pressing cage 4 is a horizontally arranged conical container with gaps; the feeding cylinder 2 and the wide end of the pressing cage 4 are concentrically connected; the narrow end of the pressing cage 4 is concentrically connected to a dispersing cylinder 5; the dispersing cylinder 5 is concentrically connected to the wide end of the next pressing cage 4; the pressing cage 4 and the dispersing cylinder 5 are arranged alternately; a cone block 6 is connected to the spindle 1 inside the pressing cage 4; a spiral blade 7 with a gradually decreasing pitch is connected to the cone block 6; the spiral blade 7 is in contact with the inner wall of the pressing cage 4; and dispersing blades 8 are connected to the spindle 1 inside the feeding cylinder 2 and the dispersing cylinder 5, which are formed by multiple incomplete spiral blades arranged spirally.

[0021] In operation, the oilseeds are injected into the feed cylinder 2 through the feed inlet 3. The spindle 1 drives the dispersing blade 8 to rotate, conveying the oilseeds into the gap between the press cage 4 and the cone block 6. The spindle 1 drives the spiral blade 7 to rotate. The spiral blade 7, with its gradually decreasing pitch, works in conjunction with the press cage 4 to press the oil, completing the initial pressing. The oilseeds after the initial pressing enter the dispersing cylinder 5. The spindle 1 drives the dispersing blade 8 to rotate. Under the action of the dispersing blade 8, the initially pressed oilseeds are dispersed and conveyed to the next press cage 4. This dispersing and pressing is repeated multiple times to complete the oil pressing. Dispersing the oilseeds can break down the structure of the oilseeds, exposing the parts that were not fully squeezed, allowing more oil to be squeezed out in subsequent pressing, thus increasing the oil yield.

[0022] The diameter of the narrow end of the press cage 4 gradually decreases along the oil conveying direction, and the gap between the inner wall of the press cage 4 and the cone block 6 gradually decreases along the oil conveying direction.

[0023] As the oil content in the oilseeds decreases, the oil yield is increased by reducing the diameter of the narrow end of the press cage 4 and the pressing gap, thereby increasing the pressing pressure.

[0024] The press cage 4 includes press bars 41, with multiple press bars 41 evenly distributed around the circumference and connected to two fixing rings 42 at both ends. The two fixing rings 42 are located at the wide end and narrow end of the press cage 4, respectively.

[0025] The pressing cage 4 and the dispersing cylinder 5 are fastened together with a guide cylinder 9. The guide cylinder 9 is connected to the outer surface of the dispersing cylinder 5 and is fixedly installed by a bracket 10. An oil outlet 11 is opened at the lower part of the guide cylinder 9.

[0026] During pressing, the splashed oil flows down the inner wall of the guide cylinder 9 and is discharged through the oil outlet 11, thus completing the discharge.
