Description

Technical Field

[0001] This invention relates to the field of nut roasting technology, and in particular to an automatic nut roasting and packaging equipment. Background Technology

[0002] Nuts are the essence of plants, rich in nutrients, containing high levels of protein, oils, minerals, and vitamins. They contribute to human growth and development, strengthen the body, and prevent disease, making them popular. Some nuts require drying and roasting during production, necessitating the use of specialized dryers. Current dryers typically employ a horizontal drying drum with spiral blades on a rotating shaft inside the drum. The drive motor is located outside the drum and connected to the rotating shaft at one end. This design offers high efficiency and energy savings. A heating module is installed on the drum wall. The operation process involves the operator pouring raw nuts into the horizontal drying drum; adding ingredients such as syrup; the motor drives the rotating shaft, activating the heating module; and the rotating shaft, in turn, drives the spiral blades to roast the nuts inside the drum. After roasting, the rotating shaft inside the drum is reversed, and the nuts and sand enter a separation pot. The nuts are then sold manually after separation. Its disadvantages are: the nuts accumulate in the horizontal drying drum, the drying depth is slow when turning them over, and it is not conducive to the discharge of hot steam, so the nuts are easy to reabsorb water; manual intervention is required, such as adding materials and manual weighing and packaging when selling, which prolongs the processing time and is time-consuming and labor-intensive.

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0017] Please refer to Figure 1-7 As shown, the automatic nut roasting and packaging equipment of the present invention includes a material storage chamber 1, a material roasting device, a finished product storage chamber 2 and a finished product packaging device 3. The material roasting device includes a rotating shaft 11, a spiral blade 12, a vertical roasting cylinder 13 and a stirring motor 14. The vertical baking cylinder 13 has a rotating shaft 11 at its axial center, and the power output end of the stirring motor 14 is connected to one end of the rotating shaft 11 for transmission. The spiral blades 12 are axially and continuously wound around the rotating shaft 11, and the spiral blades 12 are non-contactly connected to the wall of the vertical baking cylinder 13. The material storage chamber 1 has a discharge port 10 at the bottom. The vertical baking cylinder 13 has an inlet 131 on one side that is connected to the discharge port 10. The top of the cylinder wall has an outlet 132 that is connected to the finished product storage chamber 2. The bottom of the finished product storage chamber 2 is connected to the finished product packaging device 3. The vertical baking cylinder 13 has a heating element 15 on its cylinder wall. After the heating element 15 is powered on, it heats and bakes the inside of the vertical baking cylinder 13. Then, the spiral blades 12 stir and fry the nuts that enter the vertical baking cylinder 13. The stirring motor 14 rotates forward and backward. The outside of the vertical baking cylinder 13 is provided with a first heat insulation layer 200. The first heat insulation layer 200 is made of heat insulation material covering the outside of the vertical baking cylinder 13, thereby reducing or lowering the heat conduction from the cylinder wall of the vertical baking cylinder 13 when the heating element 15 is powered on.

[0018] A material lifting and feeding device 4 is provided between the material storage chamber 1 and the material baking device; The material lifting and feeding device 4 includes a first feeding motor 41, a feeding cylinder 42, a vertical shaft 43, and a feeding spiral blade 44 that is axially continuously wound around the vertical shaft 43. The feeding spiral blade 44 is axially placed inside the feeding cylinder 42 through the vertical shaft 43, and the power output end of the first feeding motor 41 is drivenly connected to one axial end of the vertical shaft 43. The bottom radial side of the feeding cylinder 42 is provided with a first inlet 421, and the bottom of the material storage chamber 1 is connected to the first inlet 421.

[0019] The top of the feeding cylinder 42 is radially connected to the inlet 131. The inlet 131 is located on one side of the middle of the vertical baking cylinder 13. The spiral blade 12 includes a first spiral part 203 and a second spiral part 204. The first spiral part 203 is located at the upper end of the second spiral part 204, and one end of its spiral is joined to form the spiral blade 12. The blade of the first spiral part 203 has several evenly distributed sieve holes 121. The heating element 15 is located on the cylinder wall of the vertical baking cylinder 13 around the second spiral part 204. The material lifting and feeding device 4 vertically lifts granular materials such as nuts into the inlet 131 and into the vertical roasting cylinder 13. A motor drives the rotating shaft 11 to rotate, which in turn drives the second spiral section 204, causing the granular nuts to tumble. Heating elements 15 on the cylinder wall of the vertical roasting cylinder 13 around the second spiral section 204 then roast the tumbling granules. At this time, roasting sand and seasonings can be added to the vertical roasting cylinder 13, ensuring even heating while the granules tumble and roast, and allowing for seasoning when added. The stirring motor 14 is set to rotate in both directions. When the driving spiral blades 12 rotate in reverse, the second spiral section 204 drives the granules to tumble and roast. When rotating in the forward direction, the granules are output upwards to the outlet 132 of the finished product storage chamber 2 by the spiral blades 12 formed by the splicing of the second spiral section 204 and the first spiral section 203. The bottom of the vertical roasting cylinder 13 is provided with a discharge port 205 for rinsing sand and seasonings, or for discharging impurities and seasoning mixtures. The discharge port 205 is equipped with an openable closed door, which is opened to discharge impurities, sand and seasoning mixtures when necessary.

[0020] The aperture of the sieve 121 is 1mm-25mm. It is set according to the different sizes of nuts, so that the nuts are not easy to fall into the sieve 121, and it can screen out defective products and impurities, as well as filter out roasted grains and seasonings.

[0021] A heat-insulating feeding and lifting device is installed between the finished product storage room 2 and the finished product packaging device 3; The insulated feeding and lifting device includes an insulated feeding cylinder 51, a vertical shaft 52, a second feeding motor 53, and lifting spiral blades 54. The insulated feeding cylinder 51 is provided with an insulated heating element 209 on its cylinder wall, and the lifting spiral blades 54 are axially and continuously wound around the vertical shaft 52. The insulated heating element 209 provides continuous constant temperature heating, which prevents the nuts from getting cold and damp when entering the insulated feeding cylinder 51, thus avoiding the generation of a large amount of water vapor.

[0022] The insulated feeding cylinder 51 has a second inlet 511 connected to one radial side of its bottom and a second outlet 512 connected to one radial side of its top. The finished product storage chamber 2 has a discharge hopper 21, which is connected to the second inlet 511. The second outlet 512 is connected to an outlet hopper 513, which is connected to the finished product packaging device 3. A second heat insulation layer 208 is provided on the outer wall of the insulated feeding cylinder 51, and a third heat insulation layer 206 is provided on the outer wall of the finished product storage chamber 2. The finished product packaging device 3 includes a base 31, a pre-storage compartment for packaging bags 32, a flipping drive cylinder 33, a bag-picking suction cup 34, a bag-picking drive cylinder 35, a bag-mouth suction cup 36, and a bag-opening drive cylinder 37. The base 31 has a packaging bag placement slot 311 in the middle. On both sides of the packaging bag placement slot 311, there is one or more sets of oppositely arranged bag opening drive cylinders 37. The piston rod ends of the bag opening drive cylinders 37 are opposite to each other, and each piston rod end is provided with a bag mouth suction cup 36. The pre-storage compartment 32 of the packaging bag is located above one side of the base 31. The lower end of the pre-storage compartment 32 of the packaging bag is provided with a bag outlet 321. Below the bag outlet 321 is a bag-removing driving cylinder 35. The cylinder body end of the bag-removing driving cylinder 35 is connected by a horizontally arranged rotating shaft 38, and its piston rod end is provided with a bag-removing suction cup 34. The flipping drive cylinder 33 is located below the bag-removing drive cylinder 35 inside the base 31. The cylinder body end of the flipping drive cylinder 33 is hinged to the bottom of the base 31, and its piston rod end is radially eccentrically hinged to the rotating shaft 38. The rotating shaft 38 is rotated by the extension and retraction of the flipping drive cylinder 33. At the same time as the rotating shaft 38 rotates, the bag-removing drive cylinder 35 is driven to swing back and forth from the bag outlet 321 to the packaging bag placement slot 311. One end of the discharge hopper 513, which is connected to the second discharge port 512, is located above the packaging bag placement slot 311. A weighing device 6 is provided at the bottom of the packaging bag placement slot 311.

[0023] The aforementioned nut roasting and packaging equipment also includes a steam treatment device 7, a support frame 8, and a cover 9. The material storage chamber 1, the material roasting device, the finished product storage chamber 2, the finished product packaging device 3, and the steam treatment device 7 are all arranged inside the cover 9 via the support frame 8. The top of the vertical roasting cylinder 13 is provided with a steam and flue gas collection and exhaust port 130. The steam and flue gas collection and exhaust port 130 is connected to the steam treatment device 7 via an exhaust collection pipe. This prevents steam and flue gas from accumulating inside the material roasting device.

[0024] The first inlet 421, inlet 131, outlet 132, second inlet 511, and second outlet 512 are all equipped with doors that can be opened independently.

[0025] The automatic nut roasting and packaging equipment achieves automated operation through a control system. Nuts stored in the material storage chamber 1 are controlled to enter the material lifting and feeding device 4. Within the material lifting and feeding device 4, the feeding spiral blades 44 lift and feed the nuts through the inlet 131 into the material roasting device for tumbling and roasting. Afterward, the nuts are output through the outlet 132 into the finished product storage chamber 2 for storage. The door of the second inlet 511 is opened, allowing the roasted nuts to enter the heat-insulating feeding and lifting device, and then be lifted by the lifting spiral blades 54. At this point, the door of the second outlet 512 is opened, allowing the nuts to enter the outlet hopper 513. When packaging is required... When the bag-removing drive cylinder 35 is activated, the bag-removing suction cup 34 enters the pre-storage compartment 32 to pick up the pre-folded packaging bag. The pre-storage compartment 32 contains several packaging bags stacked from bottom to top. The bag-removing suction cup 34 picks up the packaging bag, and then the flipping drive cylinder 33 drives the rotating shaft 38 to rotate. At the same time, the rotation causes the bag-removing drive cylinder 35 to flip into the packaging bag placement slot 311. Then the bag-removing suction cup 34 picks up the side of the packaging bag and falls into the packaging bag placement slot 311. Then the bag-removing suction cup 34 is disabled and the bag-removing drive cylinder 35 is controlled to retract the piston rod end. Then the flipping drive cylinder 33 and the rotating shaft 38 and the bag-removing drive cylinder 35 return to their original positions to wait for the next bag removal. Next, by controlling the piston rod end of the double-sided bag opening drive cylinder 37 to extend into one side of the packaging bag placement slot 311 and make the bag mouth suction cups 36 stick to both sides of the packaging bag, the suction cups 36 of each bag mouth will then suck up the packaging bag. Then, by controlling the piston rod end of the double-sided bag opening drive cylinder 37 to retract to both sides of the packaging bag placement slot 311, the suction cups 36 of each side will suck open the packaging bag. At this time, by controlling the door of the second discharge port 512, the nuts fall into the packaging bag through the discharge hopper 513. The weighing device 6 at the bottom of the packaging bag placement slot 311 is used to weigh the nuts falling into the packaging bag in real time. When the set weight value is reached, the system is fed back and the door of the second discharge port 512 is closed, thus stopping the continued falling of nuts into the packaging bag. Finally, a packaging bag ejection mechanism can be set in the packaging bag placement slot 311, so that the packaging bag containing nuts is pushed out to the outlet, and the operator can take out the packaging bag containing the required weight of nuts from the outlet.

[0026] In specific embodiments of the present invention, such as Figure 2 , 3 As shown, the second spiral section 204 is composed of several spiral blades 210 spliced ​​together along their axes. Each spiral blade 210 has a hinge shaft 211 on its lower side. One end of the hinge shaft 211 is radially fixed to the rotating shaft 11. Each spiral blade 210 is hinged to its corresponding hinge shaft 211. Each spiral blade 210 has a stirring blade 212 on its lower side, and each stirring blade 212 is spliced ​​to the axial upper edge of its corresponding spiral blade 210. When the power output end of the stirring motor 14 drives the rotating shaft 11 as follows... Figure 3When rotated counterclockwise as shown, each spiral blade of the second spiral section 204 rotates around the hinge axis by an angle, causing each spiral blade to fold downwards towards the stirring blade 212, thereby stirring the nuts and roasted grain mixture at the bottom of the vertical roasting cylinder 13. Since each stirring blade 212 is a single unit, its stirring effect is enhanced. When the power output end of the stirring motor 14 drives the rotating shaft 11 as shown... Figure 2 When rotated clockwise as shown, each spiral blade of the second spiral section 204 returns to its original position around the hinge axis, and the spiral blades are spliced ​​together to form a continuous spiral structure, thereby conveying the nut material and roasted grain mixture at the bottom of the vertical roasting cylinder 13 upward to the first spiral section 203. After entering the first spiral section 203, the nut material and roasted grain mixture fall through the sieve hole 121 to remove sand and impurities, while the nut material continues to be conveyed by the first spiral section 203 to the discharge port 132 and then enters the finished product storage chamber 2.

[0027] The automatic nut roasting and packaging equipment of this invention can realize the sale of finished nut products by scanning codes through a control system and control network. After the demand is confirmed, the automatic nut roasting and packaging equipment is controlled by the control system to complete the process of turning raw nut products into marketable finished products, without the need for on-site operation by maintenance personnel. Material storage chamber 1 and finished product storage chamber 2 are respectively equipped with material low-level sensors and material high-level sensors. If the raw nut products in material storage chamber 1 are lower than the storage limit, a signal is sent to the maintenance personnel to add materials. If the raw nut products in finished product storage chamber 2 are lower than the storage limit, a signal can be sent to start the previous process, thereby ensuring the finished product inventory in finished product storage chamber 2. If the raw nut products in finished product storage chamber 2 are higher than the storage limit, a signal can be sent to stop the previous process.
