Two or more meshing rotors rotate inside the pump housing. A sealed chamber is formed between the rotors and the pump housing. As the rotors rotate, the volume of the chamber changes. A negative pressure is created at the inlet, sucking the broad - bean paste from the hopper into the pump. Then, at the outlet, as the volume of the chamber decreases, the broad - bean paste is extruded out, thus achieving the conveyance of the material.
Parameters such as the rotational speed, rotation angle, and running time of the rotor pump are precisely controlled by a servo motor. According to the set filling volume, the servo motor accurately drives the operation of the rotor pump to ensure that the amount of broad - bean paste filled each time is precisely consistent. Meanwhile, the servo system can achieve rapid response and precise positioning, improving the filling efficiency and accuracy.
The precise control of the servo motor combined with the stable conveyance of the rotor pump enables the filling accuracy to be controlled at a high level, generally within ±1%, reducing the waste of sauce and cost losses.
It can be used for filling broad - bean paste of various viscosities, including sauces with large - sized broad - bean grains. It is also applicable to various viscous sauces such as chili sauce, peanut butter, and sesame paste.
The structure of the rotor pump is relatively simple, and it cooperates well with the servo system. During operation, it has low vibration and noise, can work stably for a long time, reduces the equipment failure rate, and improves production efficiency.
Components in contact with the sauce, such as the rotors and the pump housing, usually adopt a design that is easy to disassemble and clean. This facilitates thorough cleaning after the production is completed, meeting food hygiene standards.
It can be linked with other packaging equipment to automate a series of processes, including sauce conveyance, filling, capping, and labeling. This reduces manual intervention and improves the stability and consistency of the production process.
Large - scale broad - bean paste production enterprises can use the servo - rotor - pump broad - bean paste filling machine to meet the high - speed and efficient filling requirements, ensuring product quality and production efficiency.
Small - and medium - scale condiment workshops can choose a small - sized servo - rotor - pump broad - bean paste filling machine to achieve semi - automatic or fully - automatic filling. This improves the degree of production automation and filling accuracy, enhancing the competitiveness of their products.
It is used to fill broad - bean paste into packaging containers of different specifications, providing convenient packaged sauces for catering enterprises and meeting the needs of different customers.
