Figure 1 is a schematic diagram of a spice brewing tank in related technology. As shown in Figure 1, taking a 100L spice mixing tank as an example, the automatic tipping robot will tip the barreled main ingredient base into the mixing tank, and the high-precision scale at the bottom of the tank will measure the actual weight of the liquid introduced. The control system will Formula parameters, calculate the actual amount of formula solvent that should be added, and send ingredients A, ingredient B and other components to the preparation tank through pipeline transportation. The actual amount of ingredients added is measured by a high-precision scale at the bottom of the tank. After all the spices are canned, the system automatically starts the stirring motor to mix all the additives evenly to complete the spice preparation. The finished spice liquid is discharged by its own weight from the tank bottom valve located at the bottom and sent to each point of use. After the spice liquid is completely discharged, the system will automatically open the cleaning valve, send hot water to the tank through the pipeline, start the stirring motor, and discharge it through the tank bottom valve. Repeat this three times to finally complete the cleaning of the mixing tank.

Through research, the inventor found that in related technologies, due to the heavy weight of the tank, the measurement accuracy of high-precision scales was insufficient: taking a 100L material liquid preparation tank as an example, due to process requirements, steam heating is required during the spice preparation process to improve the uniformity of preparation. Therefore, the tank adopts a double-shell pressure vessel with an all-stainless steel structure. After weighing, the tank has a dead weight of about 200kg. At the same time, the tank has a volume of 100L and the liquid that can be canned weighs about 100kg. According to the industrial high-precision scale Commonly used specifications are 150kg, 300kg, 600kg, 1500kg and 3000kg. Therefore, the 300kg weighing scale is selected here. At the same time, according to the two-level single-level single-range 30000e standard, the absolute accuracy of the scale is 300kg/30000=10g. The relative accuracy of the scale is 5‰, so the minimum weighing weight to ensure accuracy is 10/5‰=2kg, that is, if the weighed weight is less than 2kg, accuracy cannot be guaranteed.

In the actual production process, seaweed extract and other formulas need to be added to the finished spices, and the minimum measurement weight is about 1.2kg. If the above-mentioned high-precision scale with a single measurement range of 300kg is used, the minimum measurement accuracy weight is 2kg, which cannot meet the minimum formula amount of 1.2kg. measurement accuracy requirements.
