Description

Technical Field

[0001] The invention relates to the technical field of green coffee bean scenting, in particular to green coffee bean aroma scenting equipment. Background Art

[0002] The traditional coffee making process mainly focuses on the roasting and grinding of coffee beans. The flavor of coffee mainly depends on the variety characteristics and origin of the coffee beans themselves. In order to meet consumers' growing desire to explore new flavors, many manufacturers use "aroma enhancement" to make coffee have a richer and more personalized flavor. However, most of the methods on the market are to add artificial flavors or simply mix after roasting, which lacks natural and unique flavor fusion methods.

[0064] Raw material preparation: Select high-quality green coffee beans, wash and screen them, remove impurities and bad coffee beans, ensure the quality and consistency of the coffee beans, and evenly spread the green coffee beans on each layer of the filter 44. The thickness of the coffee beans on each layer of the filter 44 should not be too thick, generally controlled to about 5-10 cm, to ensure that the floral aroma can fully penetrate;

[0065] Prepare fresh floral ingredients, such as jasmine and rose, etc. According to the amount of green coffee beans and the required floral concentration, reasonably determine the amount of floral ingredients to be used, properly process the floral ingredients, such as removing impurities such as peduncles and flower stalks, and then evenly place them between the layers of green coffee beans;

[0066] Parameter setting: According to the selected floral aroma raw materials and coffee bean varieties, select a suitable preset scenting process program or set the parameters by yourself through the operation interface of the controller 18, set the temperature range to 30°C-40°C (the specific temperature can be adjusted according to the actual situation), the humidity range to 60%-80%RH, the stirring speed to 10-20 revolutions per minute, the stirring time interval to 2-3 hours, and the scenting time to 12-24 hours (the specific time is determined according to the floral aroma type and the required flavor intensity);

[0067] Start the scenting process: after confirming that all parameters are set correctly, start the equipment to start scenting. The equipment automatically runs according to the set program, and the heating plate 8 starts heating, so that the temperature in the scenting cylinder 1 gradually rises to the set value; the humidifier 11 and the dehumidifier 12 automatically adjust the humidity according to the feedback data of the humidity sensor 10 to keep it within the set range; the fan 64 inside the air duct 61 arranged above and below continues to run to promote air circulation and gas exchange inside the scenting cylinder 1;

[0068] During the scenting process, the stirring system 5 automatically starts at a set time interval and speed to realize the rotation of the stirring shaft 53. Therefore, the connecting rods 54 installed on both sides of the stirring shaft 53 can cooperate with the multiple stirring blades 55 installed at equal intervals at the bottom to stir the coffee beans and floral aroma materials placed on each layer of the filter frame 43 and the filter screen 44, so that the coffee beans and the floral aroma materials are fully mixed and evenly mixed, ensuring that the floral aroma can be evenly penetrated into the coffee beans. Secondly, because the multiple stirring blades 55 are arranged in a flexible shape as a whole, efficient stirring and mixing activities can be achieved without damaging the coffee beans. Moreover, during the stirring process of the multiple stirring blades 55, their flexible shape can cause elastic deformation when they come into contact with the outer wall of the filter frame 43, so that the stirring is blocked during the rotation and stirring process.

[0069] Process monitoring and adjustment: During the scenting process, the temperature, humidity, stirring state and other parameter changes in the container are monitored in real time through the display screen of the controller 18. If the actual parameters deviate from the set values, the system will automatically adjust. For example, if the temperature is too high, the controller 18 will automatically reduce the power of the heating plate 8 or stop heating; if the humidity is low, the humidifier 11 will automatically increase the humidification amount; if the humidity is high, the dehumidifier 12 will automatically start to dehumidify;

[0070] At the same time, regularly observe the status of green coffee beans and floral aroma raw materials, such as whether there are any abnormalities such as odor or discoloration. If any abnormality is found, the scenting process should be stopped in time, the equipment and raw materials should be checked, and the problem should be found and dealt with;

[0071] Scenting completion and discharge: When the set scenting time is reached, the equipment automatically stops running, opens the top cover 2 at the upper end of the scenting cylinder 1, and allows the floral aroma in the scenting cylinder 1 to dissipate for a period of time. At this time, the motor 410 arranged on the left side of the scenting cylinder 1 can be driven to rotate the screw 49 connected to the upper end. As the screw 49 rotates, the side block 48 threadedly connected to the multi-section external thread of the screw 49 will realize the upward movement of the docking ring 41. When the docking ring 41 moves upward, the filter frame 43 connected to the internal slot 42 of the docking ring 41 will realize the synchronous upward movement of the filter screens 44 arranged on both sides of the interior, and the filter screens 44 on both sides of the filter screens will move upward. When the screen 44 moves upward with the filter frame 43, one side of the inner part of the filter screens 44 on both sides will abut against the vertical shafts 56 provided at the lower ends of the connecting rods 54 on both sides, and in the subsequent upward movement process, the vertical shafts 56 realize the squeezing and pushing of the filter screen 44, so that the filter screen 44 cooperates with the connecting shafts 46 provided at both ends of one side to perform a tilting and opening activity, and as the filter screens 44 on both sides are opened at the same time, the green coffee beans and floral aroma materials between the filter screens 44 and the filter frame 43 will perform a falling and discharging activity, so that the green coffee beans and floral aroma materials fall onto the inclined plate 13 provided at the lower end of the inner part of the scenting cylinder 1, and enter the screening system 15 from the discharge port 14 along the tilting direction of the inclined plate 13;

[0072] When the filter screens 44 on both sides are pushed to open by the corresponding vertical shafts 56, the torsion springs 47 installed on both sides of the connecting shaft 46 can realize compression activity during the rotation process. In this way, after the subsequent tilting and falling discharging activity of the green coffee beans and the floral aroma raw materials is completed, the motor 410 is driven again to make the screw 49 pass through the side block 48 to realize the downward movement and reset activity of the docking ring 41, the filter frame 43 and the filter screen 44. The rebound assistance of the torsion spring 47 can make the filter screens 44 opened on both sides automatically close and reset, so as to place new green coffee beans and floral aroma raw materials again for scenting, which greatly improves the convenience of using the equipment and does not require manual flipping. At the same time, when the filter screen 44 needs to be replaced, the cylinder door 17 provided on the front side of the scenting cylinder 1 can be opened to expose the layered structure 4 as a whole. Therefore, the filter frame 43 can be removed from the inside of the card slot 42 by pulling the filter frame 43 as a whole, so as to realize the convenient replacement of the filter screens 44 on both sides inside the filter frame 43.

[0073] When the green coffee beans and floral aroma materials that have completed the scenting enter the screening box 151 from the discharge port 14, the green coffee beans and the floral aroma materials will simultaneously fall onto the sieve plate 152 provided at the upper end of the screening box 151. The sieve plate 152 can assist in the screening of the green coffee beans and the floral aroma materials, so that the green coffee beans can pass through the sieve plate 152 and fall to the upper end of the guide plate 157. The green coffee beans and the floral aroma materials that have completed the screening can be discharged from the corresponding second discharge port 158 ​​and the first discharge port 153 along the guidance of the inclined guide plate 157 and the sieve plate 152. In this way, the floral aroma scenting activity of the green coffee beans can be completed. At the same time, in order to speed up the screening efficiency, before the green coffee beans and the floral aroma materials enter the screening box 151, the servo motor 1511 provided at the lower end of the screening box 151 can be driven to make the servo motor 1511 realize the rotation of the cam 1510 connected to the front side. When the wheel 1510 rotates, the connecting frame 159 connected to the upper end will be pushed up, and as the connecting frame 159 pushes up and down, the sieve plate 152 docked to the upper end of the connecting frame 159 will move up synchronously, and the docking rods 154 arranged at the bottom of the left and right sides will be pulled, and as the docking rods 154 on both sides move up and down, the first compression springs 155 and the second compression springs 156 installed on the upper and lower sides of the docking rods 154 will realize compression and tension activities, so that when the cam 1510 completes the pushing activity of the connecting frame 159, the rebound assistance of the first compression spring 155 and the second compression spring 156 can make the sieve plate 152 automatically move down, so that the sieve plate 152 performs elastic vibration activities, so that when the green coffee beans and the floral aroma raw materials fall to the upper end of the reciprocatingly vibrating sieve plate 152, the vibration effect can be used to assist in accelerating the screening efficiency of the green coffee beans and the floral aroma raw materials, and realize the auxiliary enhancement of the efficiency of the green coffee beans and floral aroma scenting.

[0074] Subsequently, after the coffee beans have completed the scenting process, they need to undergo quality testing, that is, testing of the degree of absorption of floral aroma, the appearance and taste of the coffee beans. If they meet the quality requirements, they can then undergo subsequent processing (such as baking). If the quality does not meet the requirements, the reasons can be analyzed, and the process parameters can be adjusted before scenting again.
