The rotor pump is mainly composed of a pair of synchronously rotating rotors (such as gear rotors, cam rotors, etc.). These rotors rotate within the pump body and transport the liquid by periodically changing the volume of the pump chamber. When the rotors turn, the liquid is sucked into the pump chamber. As the rotors continue to rotate, the liquid is carried to the outlet and then extruded under pressure, thus achieving the liquid transportation. Take the gear rotor pump as an example. Two meshing gears rotate inside the pump casing. The liquid is drawn in from the meshing area of the gears. As the gears rotate, the liquid is transported to the outlet through the space between the gears and the pump casing.
Under the action of the rotor pump, the liquid is transported from the liquid storage tank to the filling head. When the container reaches the filling position, the valve of the filling head opens, and the liquid flows into the container under the pressure of the pump. By controlling the opening time of the valve or the rotational speed of the pump, the filling volume can be accurately controlled.
It is used to store the hot - state maltose to be filled. Usually, it has heating and heat - preservation functions to maintain the fluidity of maltose and prevent it from solidifying and caking. There may also be a stirring device inside the tank to keep the temperature and concentration of maltose uniform.
It is one of the core components of the filling machine, responsible for transporting the maltose from the storage tank to the filling head. Through the servo motor, the rotational speed and rotation angle of the rotor pump can be precisely controlled, thereby achieving high - precision quantitative filling.
It is the part that directly fills the maltose into the packaging containers. The number of filling heads depends on the model and production capacity of the filling machine. The filling heads usually adopt special designs, such as having anti - drip devices, which can prevent the maltose from dripping outside the packaging containers after filling and affecting the packaging quality.
It includes conveyor belts, bottle unscramblers, etc. It is used to transport the packaging containers to be filled (such as bottles, cans, etc.) to the filling position and send them out of the filling machine after filling. The bottle unscrambler can arrange the messy packaging containers neatly to meet the filling requirements.
To ensure the fluidity of maltose during the filling process, the filling machine is equipped with heating devices, such as electric heating tubes and steam heating jackets. At the same time, there are temperature sensors and controllers that can monitor and control the temperature of maltose in real - time to ensure it is within the set temperature range.
It uses a PLC controller, a touch - screen and other human - machine interfaces to achieve automatic control of the filling machine. Operators can set parameters such as filling volume, filling speed, and temperature on the touch - screen, and the system will automatically control the operation of each component according to the set values.
The servo rotor pump can precisely control the flow rate. Combined with an advanced electrical control system, it can achieve high - precision quantitative filling. The filling accuracy can usually reach within ±1%, ensuring that the filling volume of each bottle or bag of maltose is accurate and consistent.
The components in contact with maltose, such as pipes, valves, and filling heads, are all made of corrosion - resistant stainless steel materials, which can withstand the erosion of hot - state maltose and ensure the normal operation and service life of the equipment.
Through the special design of the filling nozzle and the control program, the stringing and dripping of maltose can be effectively prevented during the filling process, keeping the packaging containers and the working environment clean and improving the appearance quality of the product.
With an intelligent control system, functions such as automatic bottle unscrambling, automatic filling, and automatic sealing can be realized, reducing manual operations, improving production efficiency and product quality stability. At the same time, the equipment also has automatic fault alarm and diagnosis functions, which is convenient for maintenance and management.
The number, position, and height of the filling heads can be flexibly adjusted according to different packaging containers and filling requirements to adapt to the filling of various specifications of glass bottles, plastic bottles, cans, and other packaging containers. In addition, by adjusting the rotational speed of the rotor pump and the filling time, the filling requirements of maltose with different viscosities can be met.
It is mainly applied in maltose production enterprises in the food processing industry to fill the cooked hot - state maltose into packaging containers such as glass bottles, plastic bottles, and cans for easy storage, transportation, and sales. In addition, in some food production enterprises such as pastry and confectionery, it can also be used to fill maltose as a filling or additive into corresponding food products. At the same time, in the condiment industry, in the production process of some condiments using maltose as a raw material or additive, such as malt syrup and honey maltose sauce, the servo rotor pump hot - filling maltose filling machine is also used to fill the products into packaging containers of various specifications to meet market demand.
