The weighing tank system collects the real-time data of the material weight, which is used to release the material that reaches the set weight in the reaction tank, set the dosage value, feed speed, etc., and start the mixing system. The vibrator then vibrates regularly under the control of the system to send the material from the feed channel to the reaction tank. At the same time, the A/D converter continuously detects the output of the load cell, converts it into a digital quantity, and transmits it to the control system for processing. After digital filtering and scale transformation, on the one hand, the instantaneous object weight is displayed in the LCD module, and on the other hand, the measuring tank is weighed and compared. When the set value is reached, the feed is stopped, and the signal of the weighing module is detected, and the gate is opened to release the material, so as to realize automatic weighing.
020-34563445The automatic batching control system searches the corresponding level of formula parameters in the raw material pre-batching database according to the batching work order issued by the production manager or manually recorded, calculates the weight of raw materials required to be batching, and then decompositions the name and weight of all raw materials involved in the batching according to the formula, and reminds the operator to supplement the missing raw materials. At the same time, the monitoring screen shows the amount of ingredients that need to be added. The missing raw materials are manually sent from the raw material storage area to the mixing area, and then the corresponding amount of liquid is automatically added (the amount of liquid is measured by the weighing module of the boiling tank itself). After the filling of liquid, 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 boiling of raw materials. The boiled raw materials are temporarily stored in the cooking tank and used as raw materials.
When preparing the material liquid, the dosing machine first controls the valve positioner to make the pneumatic ball valve fully open, so that raw materials quickly flow into the metering tank when preparing the material liquid, the dosing machine first controls the valve positioner to make the pneumatic ball valve fully open, so that raw materials quickly flow into the metering tank when the amount of raw materials is close to the set value, control 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, the pneumatic ball valve is completely closed to meet the requirements of preparation speed and feed liquid accuracy. The raw material preparation sequence is to prepare moisturizer first, then prepare other raw materials, and finally prepare liquid (also measured by the metering tank), which can reduce the raw material loss; After the preparation of all raw materials involved in the automatic proportioning, the automatic control system will automatically purge and clean the main proportioning pipe (using hot water cleaning); Then, according to the name and weight information of the ingredients that need to be added manually on the monitor or the touch screen near the brewing pot, the corresponding amount of ingredients is manually weighed and poured into the selected brewing pot.
