According to the seasoning work order issued by the production management or manually entered, the weighing reactor automatically retrieves the formula parameters of the corresponding brand in the raw material pre-preparation database, calculates the weight of the feed liquid to be prepared, decompositions the name and weight of all raw materials involved in the preparation according to the formula, and reminds the operator to supplement the missing raw materials, and displays the amount of raw materials to be added on the monitoring screen. After the missing raw material is manually sent from the raw material reservoir to the feed liquid mixing area, and the raw material is sent to the corresponding raw material storage tank through the hydraulic lifting platform or air pump, the automatic feeding system automatically checks the weight of the supplementary raw material.

In order to increase the flow of raw materials in the pipeline and reduce the loss during the transportation process, the high viscosity liquid and the moisturizing agent and other raw materials are pretreated in the reaction kettle. After the operator selects the name, weight and the corresponding reactor of the raw material to be configured, the automatic feeding system automatically calculates the amount of raw material and the amount of water to be added by searching the formula parameters of the corresponding brand in the raw material preparation database, and prompts the operator to add the raw material to the selected reactor; Then, the corresponding water amount is automatically added and measured by the weighing module of the reactor itself. After the water is added, the heating, stirring and heat preservation process is automatically performed according to the stirring time and temperature in the formula library parameters (or input by the operator) to complete the configuration of raw materials. The configured raw materials are temporarily stored in the reactor and used as raw materials.

When preparing the material liquid, the control system first controls the valve positioner to fully open the pneumatic ball valve, so that raw materials quickly flow into the metering tank, when the amount of raw materials is close to the set value, and then controls the valve positioner to adjust the opening of the pneumatic ball valve, so that raw materials slowly flow into the metering tank, until the amount of raw materials reaches the set value before completely closing the pneumatic ball valve, which can simultaneously meet the requirements of the speed and accuracy of the material liquid preparation. The preparation sequence of raw materials is the first preservative, then other raw materials, and the last ingredient water (water is also measured by the metering tank), which can reduce the loss of raw materials; After the preparation of all the raw materials involved in the automatic ratio is finished, the automatic feeding system will automatically purge and clean the dosing pipe (using hot water cleaning); Then, according to the name and weight information of the raw material to be added manually that pops up on the touch screen set near the mixing tank, the corresponding amount of raw material is manually weighed to the mixing tank selected by the person.
