Optionally, the level indicator 33 is connected to a display for displaying the level. The load cell 43 is connected to a display for displaying the weight value sensed by the load cell.

For example, as shown in fig. 1 and 3, the number of the storage tanks in the feed precise micro-dispensing system is A, B, C, D, E, F, G, and X in fig. 3 may represent the number of different storage tanks, for example, a number in C, D, E, F, G.

The upper computer is provided with a certain feed fine material comprising 6.85kg methionine, 3.55kg vitamin C,5.5kg sodium chloride, 0.35kg lysine, 2.5kg magnesium chloride, 1.35kg yeast culture and 1.0kg composite mycotoxin adsorbent.

And sets a charging rule of the storage tank, when the material level detector 33 in one storage tank 3 senses that the material level reaches a set high limit value, the high-level travel switch 341 controls the high-level indicating device 342 to give an alarm, the charging of the storage tank 3 should be stopped, and when the material level detector 33 senses that the material level reaches a set low limit value, the low-level travel switch 351 controls the low-level indicating device 352 to give an alarm, and the charging of the storage tank 3 should be handled.

After the upper computer 62 sets the feed preparation data in the feed precise micro-preparation system, the feed precise micro-preparation system is started, the controller controls the driving device of the feeding mechanism 1 and the driving device of the rotary distributor 2 to operate, and methionine, vitamin C, sodium chloride, lysine, magnesium chloride, yeast culture and composite mycotoxin adsorbent are sequentially and respectively conveyed into a storage tank with the number A, B, C, D, E, F, G, so that the material level in the storage tank A, B, C, D, E, F, G is between the high limit value and the low limit value.

In the specific preparation process, the controller 61 firstly controls the stirring driving device 361 at the top of the storage tank 3 to start, then controls the driving device of the first discharging mechanism 32 at the bottom of the storage tank 3 to start, at this time, the first discharging mechanism 32 conveys 6.85kg of methionine stored in the storage tank 3 to the metering tank 4, when the weight in the metering tank 4 fed back by the weighing sensor 43 is up to 6.85kg, the controller 61 controls the driving device of the first discharging mechanism 32 at the bottom of the storage tank 3 to stop running, and then the controller 61 controls the stirring driving device 361 at the top of the storage tank 3 to stop running, so that the metering of methionine is completed. Subsequently, the controller 61 controls the stirring driving device 361 at the top of the B tank 3 to start again, then the controller 61 controls the driving device of the first discharging mechanism 32 at the bottom of the B tank to start, at this time, the first discharging mechanism 32 delivers 3.55kg of vitamin C stored in the B tank 3 into the metering tank 4, and when the weight in the metering tank 4 fed back by the weighing sensor 43 is added up to 3.55kg (weight of methionine) +6.85kg (weight of vitamin C) =10.4 kg by the controller, the controller 61 controls the driving device of the first discharging mechanism 32 at the bottom of the B tank 3 to stop operating, and then the controller 61 controls the stirring driving device 361 at the top of the B tank 3 to stop operating, thus completing the metering of vitamin C. The accurate micro-compounding system of the feed has the same process of metering sodium chloride, lysine, magnesium chloride, yeast culture and composite mycotoxin adsorbent as the process of metering methionine and vitamin C. After the cumulative metering of methionine, vitamin C, sodium chloride, lysine, magnesium chloride, yeast culture and composite mycotoxin adsorbent is completed, the upper computer displays that the cumulative weight in the metering tank 4 fed back by the weighing sensor 43 is 6.85kg (weight of methionine) +3.55kg (weight of vitamin C) +5.5kg (weight of sodium chloride) +0.35kg (weight of lysine) +2.5kg (weight of magnesium chloride) +1.35kg (weight of yeast culture) +1.0kg (weight of composite mycotoxin adsorbent) =21.1 kg, and the controller 61 controls the driving device of the second discharging mechanism 42 at the bottom of the metering tank 4 to operate so as to discharge the methionine, vitamin C, sodium chloride, lysine, magnesium chloride, yeast culture and composite mycotoxin adsorbent in the metering tank.

Further, since the discharge port of the first discharge machine 32 at the lower part of the storage tank 3 is directly and hard connected with the fourth feed port 41 at the top of the metering tank 4, the weighing process of the metering tank 4 is interfered by the storage tank 3 and the first discharge machine 32, and the metering tank metering is inaccurate.
