Description

Technical Field

[0001] The utility model relates to the technical field of edible sesame oil production, in particular to oil pressing equipment for edible sesame oil production. Background Art

[0002] Oil pressing is a method of extracting oil from oilseeds by mechanical force. The depth of the oil pressing and the pressure on the material during pressing are determined by the oil pressing method. Oil pressing can be divided into single pressing and pre-pressing with leaching.

[0003] Chinese patent publication number CN216001586U discloses a pre-pressing device for edible oil production. Because the screw pressing shaft rotates during operation, it requires low speed and high torque when moving horizontally. Therefore, the servo motor transmits low speed and high torque to the rotating gear through the worm reducer, and the rotating gear transmits it to the transmission gear, which drives the adjusting nut barrel to rotate. By controlling the speed and number of turns of the motor, the forward or backward distance of the advance and retreat threads can be precisely controlled, ensuring the stability of the screw oil press operation.

[0004] In the above patent, a large amount of oil cake residue produced during the screw pressing process will remain inside the screw pressing shaft. As the oil cake residue is continuously pressed, it will absorb a small amount of sesame oil again, thereby affecting the overall oil yield of sesame oil. Utility Model Content

[0005] The utility model aims to provide an oil pressing device for producing edible sesame oil. Under the rotation of the pressing knife roller, the pressing knife roller moves from the feeding end to the discharging end. During the process, the sesame seeds are squeezed and crushed, and the produced oil is discharged from the oil outlet hole, while the oil cake residue is accumulated above the oil outlet hole. As subsequent sesame seeds are continuously added, the early oil cake residue will be squeezed out and will be squeezed twice during the process. In this way, the oil cake residue can be prevented from taking away the oil in the cavity when being discharged, and the problems in the prior art can be solved.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil pressing device for producing edible sesame oil, comprising a horizontal platform frame and a spiral pressing drum, a support is provided on one side of the bottom of the horizontal platform frame, a valve seat is provided above the support, the spiral pressing drum is connected to the support through the valve seat, a feeding hopper is provided above one end of the spiral pressing drum, a baffle plate is provided on one side of the top of the feeding hopper, the baffle plate is connected to the feeding hopper through a slot, a hanging bracket is provided on one side of the top of the horizontal platform frame, the hanging bracket is slidably connected to the horizontal platform frame through an electrically controlled rack rail, a pressure hammer is provided on the outside of the hanging bracket, and the pressure hammer is connected to the hanging bracket by bolts.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to solve the problem that a large amount of oil cake residue will remain inside the screw pressing shaft during the screw pressing process, and as the oil cake residue is continuously pressed, it will absorb a small amount of sesame oil again, thus affecting the overall oil yield of sesame oil; please refer to Figure 1-4 , the utility model provides the following solutions:

[0022] An oil pressing device for producing edible sesame oil, comprising a horizontal platform 1 and a spiral pressing drum 2, a support 101 is provided on one side of the bottom of the horizontal platform 1, a valve seat 1051 is provided above the support 101, the spiral pressing drum 2 is connected to the support 101 through the valve seat 1051, a feeding hopper 203 is provided above one end of the spiral pressing drum 2, a baffle plate 3 is provided on one side of the top of the feeding hopper 203, the baffle plate 3 is connected to the feeding hopper 203 through a slot, a hanging bracket 104 is provided on one side of the top of the horizontal platform 1, and the hanging bracket 104 is connected to the feeding hopper 203 through a slot. The electric-controlled rack 103 is slidably connected to the horizontal platform frame 1. A pressure hammer 105 is provided on the outside of the hanging bracket 104. The pressure hammer 105 is connected to the hanging bracket 104 by bolts. Two motor modules 107 are provided inside the horizontal platform frame 1. A cross transmission shaft 1071 is provided at one end of each motor module 107. The cross transmission shaft 1071 is rotatably connected to the motor module 107. A gate knob 102 is provided on one side of the support 101. A slag box 106 is provided inside the support 101. The slag box 106 is installed below the valve seat 1051.

[0023] In this embodiment, sesame seeds are introduced from the feeding hopper 203, and then the motor module 107 drives the pressing roller 201 inside the spiral pressing drum 2 to rotate. During the pressing process, another set of motors controls the hanging frame 104 to descend, so that the pressing hammer 105 is pressed into the feeding hopper 203. The pressing hammer 105 is used to compact the sesame seeds in the pressing hammer 105 and the spiral pressing drum 2, thereby reducing the gap space between the sesame seeds, thereby improving the pressing efficiency, and also preventing the oil cake residue from entering the feeding hopper 203 when the residue is withdrawn;

[0024] A pressing roller 201 is provided inside the spiral pressing drum 2. An adapter sleeve 2011 is provided at one end of the pressing roller 201. The pressing roller 201 is connected to the cross drive shaft 1071 via the adapter sleeve 2011. A slag discharge port 205 is provided at the bottom of one end of the spiral pressing drum 2. The slag discharge port 205 extends into the interior of the valve seat 1051. A bearing lock sleeve 202 is provided at the other end of the spiral pressing drum 2. The bearing lock sleeve 202 is connected to the spiral pressing drum 2 via an internal thread. An oil outlet 204 is provided at the bottom of the other end of the spiral pressing drum 2. The pressure hammer 105 extends into the interior of the feeding hopper 203.

[0025] In this embodiment, the diameters of the two ends of the pressing roller 201 are different. The length of the feed end is greater than that of the discharge end, but the diameter is smaller than that of the discharge end. The sesame seeds enter the interior of the spiral pressing drum 2 through the feeding hopper 203, and move from the feed end to the discharge end under the rotation of the pressing roller 201. During the process, the sesame seeds are squeezed and crushed, and the produced oil is discharged from the oil outlet 204, while the oil cake residue is accumulated above the oil outlet 204. As subsequent sesame seeds are continuously added, the early oil cake residue will be squeezed out and will be squeezed a second time during the process. This can prevent the oil cake residue from taking away the oil in the cavity when it is discharged. The squeezed oil cake residue enters the residue box 106 through the residue discharge port 205.

[0026] The working principle is that sesame seeds are introduced from the feeding hopper 203, and then the motor module 107 drives the pressing roller 201 inside the spiral pressing drum 2 to rotate. During the pressing process, another set of motors will control the hanging frame 104 to descend, so that the pressing hammer 105 is pressed into the feeding hopper 203, and the pressing hammer 105 is used to compact the sesame seeds in the pressing hammer 105 and the spiral pressing drum 2 to reduce the gap space between the sesame seeds. The sesame seeds enter the spiral pressing drum 2 through the feeding hopper 203, and move from the feed end to the discharge end under the rotation of the pressing roller 201. In the process, the sesame seeds are squeezed and crushed, and the produced oil is discharged from the oil outlet 204, while the oil cake residue accumulates above the oil outlet 204. As subsequent sesame seeds are continuously added, the early oil cake residue will be squeezed out and will be squeezed twice during the process. This can prevent the oil cake residue from taking away the oil in the cavity when it is discharged, and the squeezed oil cake residue enters the residue box 106 through the residue discharge port 205.
