It is usually composed of a pair of synchronously rotating rotors, such as gear rotors, cam rotors, etc. The rotors rotate inside the pump body, periodically changing the volume of the pump cavity. When the rotors turn, the fresh tofu skin pulp is sucked into the pump cavity. As the rotors rotate, it is carried to the outlet and then extruded under pressure, achieving stable transportation.
Driven by the rotor pump, the fresh tofu skin pulp is sent from the liquid storage tank to the filling head. The servo system precisely controls the rotational speed and rotation time of the rotor pump, thus accurately controlling the flow rate and filling volume of the fresh tofu skin pulp. When the container reaches the filling position, the valve of the filling head opens, and the fresh tofu skin pulp 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 precisely controlled to ensure the accuracy and consistency of filling.
It includes servo motors, reducers, transmission chains, etc., which provide power for the movement of various components of the filling machine and drive the transportation and filling of the fresh tofu skin pulp.
Generally, high - precision sensors or electronic scales are used to quantitatively measure the fresh tofu skin pulp to ensure the accuracy of the filling volume.
It is composed of components such as filling heads and filling valves. It is responsible for filling the quantitatively measured fresh tofu skin pulp into the containers. The filling heads can be adjusted according to the shapes and sizes of different containers, and some have anti - dripping functions.
It often adopts a combination of PLC and a touch - screen for control. Operators can set parameters such as filling volume, filling speed, and filling times on the touch - screen to achieve automated operation, and simultaneously monitor the operating status of the equipment in real - time and issue fault alarms.
It includes conveyor belts and positioning devices. The conveyor belt transports empty containers to the filling position and, after filling, transports the filled containers to the next process. The positioning device ensures that the containers can be accurately aligned with the filling head during filling, improving the filling accuracy.
With the precise control of the servo system and the rotor pump, high - precision filling of fresh tofu skin pulp can be achieved. The filling error can be controlled within a small range, meeting the strict requirements of different products for filling volume.
It can handle fresh tofu skin pulp with different viscosities and can adapt to packaging containers of different shapes and sizes, such as plastic bottles, glass bottles, metal cans, and packaging bags.
The components in contact with the fresh tofu skin pulp are generally made of food - grade stainless steel and other materials that meet hygiene standards. The surface is smooth, making it difficult for the fresh tofu skin pulp to remain, and it is easy to disassemble and clean, which meets the hygiene requirements of food production.
The working process of the rotor pump is stable. During long - term filling operations, it can maintain a stable flow rate and pressure, reducing equipment failures and filling quality problems, improving production efficiency, and being suitable for large - scale production lines of fresh tofu skin.
It is equipped with a user - friendly operation interface. After simple training, operators can proficiently master the operation method, facilitating parameter setting, startup, shutdown, etc., and reducing the technical requirements for operators.
After each use, promptly clean components of the filling machine such as the hopper, barrel, rotor pump, filling head, and pipelines to remove the remaining fresh tofu skin pulp, preventing it from drying and caking, which may affect subsequent use.
Regularly check all components of the filling machine, such as rotors, seals, valves, and pipelines, for wear, leakage, etc. If any damage is found, replace them in a timely manner to ensure the normal operation of the equipment.
Regularly lubricate the transmission components of the filling machine, such as motors, reducers, chains, and belts, which can extend the service life of the components and reduce the failure rate of the equipment.
Regularly calibrate the measurement system to ensure the accuracy of the filling volume. Standard measuring instruments can be used to detect and adjust the filling volume of the filling machine. If there is any deviation, calibrate it in a timely manner to ensure the consistency of product quality.
