[0002] Existing raw and roasted coffee beans are all manually proportioned. According to the production formula requirements: different coffee beans are weighed and proportioned by electronic scales, which takes a long time, is prone to errors, and has high labor intensity and low efficiency. Due to the different settings of bean roasting parameters for each proportion, it is easy to make mistakes in proportioning beans, resulting in changes in the flavor of the roasted beans, which do not meet customer needs and are scrapped. At the same time, an automated grinding equipment is needed. The existing manual feeding of the grinder requires continuous feeding of the grinder hopper, and the machine cannot be separated from the work of the personnel, which has high labor intensity and low efficiency.

It has fast response speed and high precision, avoiding the influence of human factors.

[0020] 4. The powder silo uses a vibrating flow aid. The coffee powder has poor fluidity and is prone to arching, which results in poor material discharge. Therefore, an arch-breaking device is needed to enhance fluidity. In the past, one method was to directly install the vibration motor on the silo wall to directly vibrate the powder down. The other method was to use compressed gas to use the pressure gas to break the powder generated on the wall to enhance fluidity. Both methods have disadvantages. The first method has large vibration and noise, and requires a relatively thick wall thickness. The screws that fix the vibration motor are easy to loosen, and the motor is prone to fall off if maintenance is not timely. Gas wall breaking is easily affected by gas pressure. The gas wall breaking effect is different under different pressures. It is necessary to ensure the stability of the gas source. Second, the gas source must be dry. Wet gas can easily cause the powder to form crusts, affecting the quality of the product. In order to avoid the above problems

[0021] 5. Use negative pressure to convey powder, which can quickly absorb powder, without residual materials in the pipeline, and can frequently change materials. It is convenient, fast, easy to operate, and low cost. In the past, auger conveying was generally used. First, the cost was high, and second, powder was easy to remain in the pipeline. When changing materials, it is necessary to clean the residue in the pipeline, otherwise the mixing will affect the product quality. The cleaning is difficult and the cycle is long, the efficiency is low, and it cannot respond to production quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Working principle: First, pour the coffee beans into the green bean loading hopper 9, and the green bean loading weighing sensor 25 weighs. Select one of the four silos 16 to be entered on the operating table, such as the No. 1 silo, and automatically open the suction valve and the air intake valve, start the first discharge valve 11 and the first air intake fan 13, and suck the material into the silo 16 through the first suction air outlet 12 of the suction machine. At the same time, the control system automatically adds the weighing weight to the corresponding silo. The four silos can load up to four types of materials. The system can match the weight arbitrarily according to the needs, set the discharge weight of each silo, and open the green bean discharge stop valve 20 in sequence according to the sequence number. Through the weighing sensor, the discharge reaches the set weight. , the green bean discharge stop valve 20 is closed, and the material bin is automatically deducted according to the weighing weight of the material discharged from each bin, and then the material enters the roasting machine for roasting. The roasting machine is an existing roasting machine. After roasting, it enters the stone remover 3 to remove stones or impurities. The cooked bean suction fan 31 is started, and the wind brought by the cooked bean suction duct 30 sucks the cooked beans into the four cooked bean silos 29 through the cooked bean silo feeding duct 27. At the same time, the control system automatically adds the weighing weight to the corresponding silo. The four silos can load four types of materials at most. The system can match the weight arbitrarily as needed, set the discharge weight of each silo, and open the cooked bean discharge stop valve 35 in sequence according to the sequence number. 8. When the material reaches the set weight, the roasted bean material discharge stop valve 35 is closed, and the material bin is automatically deducted according to the weight of each bin, and then transported to the bean grinding area. The motor drives the stirring rod 43 to stir the powder material. According to the control console, the material discharge stop valve is opened, and the material can be randomly distributed to the five grinders 46. The opening and closing of the material discharge stop valve is controlled according to the grinding time of the grinder 46. At the same time, the overflow plate 65 is used to prevent the material from overflowing and entering the powder bin hopper 48. The grinder 46 grinds the material into powder and enters the powder bin hopper 48. Because the powder material is easy to accumulate and arch, it is necessary to use a vibrator 50 to vibrate to make the material flow down, and the anti-blocking cone 49 can make the material flow down evenly and will not accumulate to the first The powder outlet 51 does not discharge smoothly, and the powder is sucked into the powder bin 7 through the powder suction air outlet 52. The material keeps falling. Due to the poor fluidity, the cone height is detected by the cone sensor 60, and the stirring motor 56 is started. The stirring paddle 55 flattens and pushes out the cone formed by the material. When the material reaches the high position sensor, the stirring motor 56 and the stirring paddle 55 stop working. When discharging the material, the discharge valve 59 and the vibrating flow aid 58 on the second powder outlet 57 are started. Due to the poor fluidity of the powder, the material is discharged from the center, and the material on the cone wall side is easy to form an arch and not flow. In this way, the vibrating flow aid 58 is needed to break the arch of the material and vibrate the material for discharge. After the discharge is completed, the material enters the packaging machine for packaging.
