Among them, wild almonds have the best effect. Wild apricots are usually used to make edible oil by pressing, which is divided into hot pressing and cold pressing. The hot pressing process is numerous and the investment cost is relatively high. Cold pressing is currently the most common method for processing wild almonds into oil. The traditional cold pressing process requires the selected wild apricots to be shelled, screened, cleaned, heated, cooled and dried, red skin removed, color sorted, selected, tempered, low-temperature pressed, impurity recovered, filtered once, finely filtered and finally packaged.

[0003] The specification of Chinese invention patent CN116898102B discloses an almond processing device, including a frame, a shelling device is arranged in the frame, the shelling device includes two extrusion plates for shelling almonds, a sliding frame for driving the extrusion plates to move, a driving mechanism and a bottom plate arranged on the frame, the sliding frame is slidably matched with the frame along the width direction of the frame, the sliding frame is provided with a slide groove along the length direction of the frame, the extrusion plate is slidably matched in the slide groove, when the extrusion plate slides along the slide groove, it is used to correct the deviation of the almonds so that the sharp edge of the almonds is arranged parallel to the extrusion plate, the sliding frame is provided with an adjusting device, the adjusting device includes an adjusting component for driving the two extrusion plates to slide and adjust in opposite directions along the slide groove and a rotating component for driving the adjusting component to move; the almond processing device of the invention has the effect of improving the processing quality of almonds.

[0004] When the almond processing device is breaking the almond shells, the almond shells are squeezed after the rubbing process to break the almond shells, resulting in the almonds being in an unconstrained state during the actual operation. Even after the shells are broken, the almonds inside need to use additional components to assist in distinguishing the shell from the kernel, which increases the workload. In addition, the accuracy of the separation cannot be guaranteed when the shell and the kernel are separated later. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to selectively constrain and limit the almonds during the extrusion process to ensure that the shell after extrusion and the almonds in the shell are fully separated, thereby reducing subsequent separation operations.

[0006] To solve the above problems, the present invention provides a production process of wild almond oil, comprising the following steps: S1, raw material selection and preparation; S11, shelling: selecting mature and dried wild apricots, and using almond shelling equipment to shell the wild apricots to obtain almonds; S12, screening: putting the obtained almonds into a vibrating screen machine to filter out impurities and shriveled almonds, leaving qualified almonds; S13, cleaning: putting the sieved almonds into clean water, soaking for 3-5 minutes, and then stirring manually to remove impurities on the surface of the almonds; S2, hot and cold drying and cooling; S3, remove the red skin on the surface of the almonds, put the almonds into the peeling machine to remove the red skin on the surface of the almonds; S4, almond processing; S5, squeezing treatment; S6, oil treatment; S7, packaging, transporting the oil after fine filtration to the fully automatic filling machine for packaging, completing the preparation of wild almond oil; The almond shelling equipment includes a No. 1 box and a No. 2 box arranged on one side of the No. 1 box.

[0007] In the above-mentioned wild almond oil production process, the almond shell can be constrained and limited after being squeezed and broken, so that the almond core inside can fall into box No. 1 by itself after being turned over, thereby realizing the separate storage of the almond core and the almond shell, reducing subsequent separation operations.

[0008] As a further improvement of the present application, the specific operation steps in the hot-cold drying and cooling in S2 are as follows: S21, heating: putting the washed almonds into warm water, heating to 100°C, and soaking for 2-3 minutes, wherein the initial temperature of the warm water is 85-90°C, and the heating speed is 10-20°C / min; S22, cooling: soak the heated almonds in cold water at 3-5°C for 4-6 minutes; S23, drying: conveying the cooled almonds into a drying box, heating to 100°C at a speed of 6-8°C / min, keeping the temperature for 6-8min, and air-drying the almonds at a wind speed of 8-10m / s.

[0019] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-Figure 9 and Fig.15 A production process of wild almond oil is shown, which includes the following steps: S1, raw material selection and preparation; S11, shelling: selecting mature and dried wild apricots, and using almond shelling equipment to shell the wild apricots to obtain almonds; S12, screening: putting the obtained almonds into a vibrating screen machine to filter out impurities and shriveled almonds, leaving qualified almonds; S13, cleaning: putting the sieved almonds into clean water, soaking for 3-5 minutes, and then stirring manually to remove impurities on the surface of the almonds; S2, hot and cold drying and cooling; S3, remove the red skin on the surface of the almonds, put the almonds into the peeling machine to remove the red skin on the surface of the almonds; S4, almond processing; S5, squeezing treatment; S6, oil treatment; S7, packaging, transporting the oil after fine filtration to the fully automatic filling machine for packaging, completing the preparation of wild almond oil; The almond shelling equipment includes a No. 1 box 1 and a No. 2 box 4 arranged on one side of the No. 1 box 1, a conveying chain 8 connected with a conveying roller 7 inside is installed above the No. 1 box 1 and the No. 2 box 4, and a driving motor 3 is connected to the surface of one of the conveying rollers 7, and a symmetrically arranged silicone plate 2 is installed on the surface of the conveying chain 8, and a plurality of equidistantly arranged constraint frames 5 are installed on the opposite surfaces of the two silicone plates 2, and the inner wall of the constraint frame 5 is installed with a symmetrically arranged arc-shaped airbag 53, and the bottom wall of the constraint frame 5 is installed with a symmetrically arranged elastic air column 51, and the tail end of the elastic air column 51 is connected with the arc-shaped airbag 53. The inner wall of the constraint frame 5 is installed with an electromagnetic sheet 52 located on the inner side of the arc-shaped airbag 53, and the inner wall of the arc-shaped airbag 53 is coated with a magnetic attraction layer that attracts the electromagnetic sheet 52. A servo motor 6 is installed on one side of the conveying chain 8. The output end of the servo motor 6 is connected to a gear column 9. The surface of the gear column 9 is meshingly connected with an extruded rack No. 1 91 and an extruded rack No. 2 93 arranged up and down. The tail ends of the extruded rack No. 1 91 and the extruded rack No. 2 93 are respectively connected to an extruded strip plate No. 1 92 and an extruded strip plate No. 2 94, and the extruded strip plate No. 1 92 and the extruded strip plate No. 2 94 are respectively located on both sides of the constraint frame 5.

[0021] The second extrusion rack 93 is located in the middle of the conveying chain 8 and below the restraining frame 5 at the upper position, and the cross section of the second extrusion strip plate 94 is stepped.

[0022] Specifically, put the almonds with shells into the constraint frame 5. If the tip of the almonds faces upward and the wide end faces downward, the wide end of the almonds can squeeze the elastic gas column 51 on the bottom wall of the constraint frame 5, so that the gas in the elastic gas column 51 is squeezed into the arc-shaped air bag 53, so that the arc-shaped air bag 53 expands, and then the surface of the almonds can be clamped and constrained. At the same time, the servo motor 6 is started to rotate forward. Under the action of the gear column 9, the first extrusion rack 91 and the second extrusion rack 93 are driven to move toward each other, and then the first extrusion strip plate 92 and the second extrusion strip plate 94 are driven to approach each other and squeeze the tip part of the surface of the almonds in the clamping and constrained state, so that the tip part of the almonds is opened. After that, the servo motor 6 rotates in the opposite direction to drive the first extrusion strip plate 92 and the second extrusion strip plate 94 to separate, and the extrusion operation is ended. When the almonds are placed in the restraint frame 5, if the tip of the almonds contacts the bottom wall of the restraint frame 5, the arc-shaped airbag 53 fails to effectively restrain the almonds. In the subsequent extrusion process, the shelled almonds may slide upward under the extrusion of the first extrusion strip 92 and the second extrusion strip 94, and then fall to the bottom of the conveyor chain 8, waiting for the second round of screening and re-extrusion to break the shells; As the conveyor chain 8 rotates, the almonds after opening are driven to the position of the second box 4, and the almond cores in the almonds can fall into the second box 4 through the opening, and then continue to move with the conveyor chain 8, driving the constraint frame 5 with only the shell remaining to move to the top of the first box 1, and then the electromagnetic sheet 52 is activated, which can drive the arc-shaped airbag 53 to become flat under the action of magnetic attraction, so that the almond shell can fall into the first box 1 (due to the friction between the almond shell and the arc-shaped airbag 53, the almond shell can be prevented from falling automatically after turning over); In addition, the stepped cross-sectional design allows the second extrusion strip 94 to move smoothly when approaching to extrude the almonds without being blocked by the surface of the restraint frame 5 .

[0023] The specific operation steps of hot and cold drying and cooling in S2 are as follows: S21, heating: putting the washed almonds into warm water, heating to 100°C, and soaking for 2-3 minutes, wherein the initial temperature of the warm water is 85-90°C, and the heating speed is 10-20°C / min; S22, cooling: soak the heated almonds in cold water at 3-5°C for 4-6 minutes; S23, drying: conveying the cooled almonds into a drying box, heating to 100°C at a speed of 6-8°C / min, keeping the temperature for 6-8min, and air-drying the almonds at a wind speed of 8-10m / s.

[0024] The specific operation steps in almond processing in S4 are as follows: S41, color sorting: put the almonds with the red skin removed into the color sorter for screening, and store the almonds with similar color differences separately; S42, selection: putting the color-selected almond hair into a selection machine to select almonds of uniform color; S43, almond conditioning: put the selected almonds into the conditioning equipment for deep treatment, the processing time is 10-12 minutes.

[0025] The specific operation steps of the squeezing process in S5 are as follows: S51, low temperature pressing: putting the conditioned almonds into the oil press to squeeze out the oil in the almonds; S52, impurity recovery: Collect the almond meal remaining after low-temperature pressing.

[0026] The specific steps of oil treatment in S6 are as follows: S61, primary filtration: the crude oil obtained after pressing is transported to a vibrating slag removal blade filter for primary filtration, and the filtration time is 8-10 minutes; S62, fine filtration: The crude oil after the primary filtration is transported to the ultra-high pressure nano homogenizer for homogenization, dispersion and filtration.

[0027] Specifically, the DZSF linear vibrating screen is used for screening in S12, the YTS-B918 color sorter is used for color sorting in S41, the SX800-4 sorter is used for fine selection in S42, the KOMET vegetable oil press is used for low-temperature pressing in S51, the APV-2000 ultra-high pressure nano homogenizer is used for fine filtration in S62, and the WX-6 fully automatic filling machine is used for packaging in S7; Compared with hot pressing, cold pressing has simpler process, lower input cost, higher production efficiency and no need to add any additives, thus improving the quality of almond oil. The use of mechanized and automatic removal of the red skin on the epidermis solves the problem that traditional manual removal of the red skin is not comprehensive, resulting in poor purity of almond oil and affecting the oil quality. It liberates labor, saves time and improves the quality of almond oil.

[0028] Second implementation method: Figure 10-13 It is shown that an adjustment frame 11 with a groove on the top is installed on the outer wall surfaces of both sides of the constraint frame 5, and the inside of the adjustment frame 11 is slidably connected with a pulling rod 10 with an L-shaped cross-section, and a screw 1101 is installed on the bottom wall of the adjustment frame 11 away from the constraint frame 5. A nut 1102 is sleeved on the surface of the screw 1101, and a movable shaft arm 1103 is connected to the surface of the nut 1102 through a movable shaft. A servo motor 1104 is installed at the bottom of the adjustment frame 11, and the output end of the servo motor 1104 is connected to the end of the screw 1101.

[0029] The thickness of the pulling rod 10 is less than 1 cm, and the pulling rod 10 is made of a high-hardness material.

[0030] The movable shaft arm 1103 is composed of two shaft arms assembled through a shaft, one of which is connected to the surface of the nut 1102 and has a length less than half of the width of the groove section, and the other shaft arm is connected to the bottom of the pulling rod 10 through a movable connecting piece.

[0031] Specifically, in order to ensure that the opening is enlarged after squeezing and facilitate the almond core inside to fall off smoothly, an adjustment frame 11 and a pulling rod 10 are designed; After the servo motor 6 rotates forward, the servo motor 1104 is started to rotate forward, thereby driving the lead screw 1101 to rotate, so that the nut 1102 drives the movable shaft arm 1103 to move downward and move away from the constraint frame 5, so that the end of the pulling rod 10 can be inserted into the opening produced after the extrusion and the pulling rod 10 moves away from the opening to pull the opening of the almond shell, so that the opening is enlarged, which is convenient for the subsequent falling off of the almond core; Then, the servo motor 1104 rotates in the reverse direction, so that the movable shaft arm 1103 is lifted and returns to its original position.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
