Principle of the Rotor Pump: Inside the rotor pump, there is a pair of rotors that rotate synchronously in opposite directions. When the motor drives the rotors to rotate, a closed chamber is formed between the rotors and the pump body, and its volume changes periodically. When the volume of the chamber increases, a negative pressure is formed at the suction port connected to the material storage tank, and the luncheon meat material is sucked into the pump chamber. When the volume of the chamber decreases, the luncheon meat material is forced out through the filling head under pressure and filled into the container.
Filling Process: The luncheon meat material is conveyed from the material storage tank to the filling head under the action of the rotor pump. The filling head is equipped with high - precision valves and flow control devices. When the packaging container reaches the filling position, the valve of the filling head opens, and the luncheon meat material 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.
High filling accuracy: Parameters such as the rotational speed of the rotor pump and the filling time can be precisely adjusted through the control system. The filling error can be controlled within a small range to ensure that the filling volume of each can of luncheon meat is accurate and consistent.
Good applicability: It can adapt to the high - viscosity characteristics of the luncheon meat material and complete the filling smoothly. Whether it is the luncheon meat raw material with more meat particles and higher viscosity or the luncheon meat filling with certain fluidity after being stirred and mixed, it can be stably conveyed and filled.
Excellent hygienic performance: Most of the components in contact with the luncheon meat material are made of food - grade stainless - steel materials, such as 304, 316L, etc. The surface is smooth, there are no unhygienic dead - ends, and it is easy to clean and disinfect, meeting the strict hygienic standards for food production.
Strong stability: The working process of the rotor pump is stable. During the long - term filling operation of luncheon meat, it can maintain a stable flow rate and pressure, reducing equipment failures and filling quality problems and improving production efficiency.
Easy to operate: It usually has a user - friendly human - machine interface. Operators can master the operation method through simple training. They can set various parameters such as filling volume and filling speed on the touch screen and view the real - time running status of the equipment.
It is mainly applied in the production and processing of luncheon meat. The well - stirred luncheon meat material is filled into different packaging containers such as metal cans and plastic boxes, preparing for subsequent processes such as sealing and sterilization, and realizing the automated and large - scale production of luncheon meat.
