Working Principle
Double Screw Conveying Principle: The two screws mesh with each other and rotate synchronously inside the pump body, forming multiple sealed chambers between them and the pump body. When the screws rotate, the satay sauce is sucked into the sealed chambers at the feed inlet due to the rotation and meshing of the screws. As the screws continue to rotate, the satay sauce in the sealed chambers is continuously pushed axially to the discharge outlet, thus realizing the conveying of the satay sauce.
Servo Control Principle: The servo motor is used to precisely control the rotation speed, rotation direction, and number of rotations of the double screws. According to the preset filling volume, the servo motor accurately drives the double screws to rotate the corresponding number of turns or angles, ensuring that the amount of satay sauce output from the discharge outlet precisely meets the set value, thus achieving precise control of the filling volume of the satay sauce.
Features
High-precision Metering: The precise cooperation between the servo motor and the double screw conveying pump can control the filling accuracy at a high level. Generally, the accuracy range can reach ±1% to ±0.5%, ensuring that the weight of each bottle or bag of satay sauce is consistent.
Wide Application Range: It can stably and smoothly fill satay sauce with different viscosities, including high-viscosity satay sauce and satay sauce containing a certain amount of particles, ensuring the filling effect.
Hygiene and Safety: The whole machine is mostly made of high-quality stainless steel, and the parts in contact with the materials are generally made of 304 stainless steel, which meets the GMP hygiene requirements and guarantees the hygiene and safety of the satay sauce during the filling process.
Anti-dripping Design: The filling nozzle is generally equipped with an advanced pneumatic anti-dripping device, which can quickly close at the moment when the filling is finished, effectively preventing the satay sauce from dripping and stringing, and keeping the filling site clean.
Easy to Operate: It is equipped with advanced operation interfaces such as a color touch screen. Users can easily perform operations such as parameter adjustment and function testing on the touch screen, reducing the technical requirements for operators.
Easy to Clean: The structure of the double screw pump is relatively simple and easy to disassemble, which is convenient for a comprehensive cleaning of the pump body and pipelines. It can effectively avoid the residue of satay sauce, reduce the difficulty and time of cleaning, and improve the maintenance efficiency of the equipment.
Technical Parameters
Filling Speed: The filling speed of a small semi-automatic filling machine is generally 10-30 bottles per minute, and the filling speed of a large fully automatic filling machine can reach 40-80 bottles per minute or even higher.
Filling Accuracy: Generally, the accuracy range can reach ±1% to ±0.5%.
Applicable Bottle or Bag Types: It can be compatible with various specifications of packaging containers. For example, the height range of bottles is 80-180mm, and the width or diameter range is 55-95mm; for satay sauce in bags, it can adapt to bags of different sizes.
Air Source Pressure: Generally, the air source pressure is required to be between 0.4-0.6MPa.
Power Supply: Commonly, it includes 220V, 380V, etc.
Maintenance and Upkeep
Daily Maintenance: After the production ends every day, promptly clean the residual sauce on the surface of the filling machine to prevent the sauce from adhering to the machine after it dries, which may affect the operation and appearance of the machine. Check whether the connections of all components are firm and whether there is any looseness. If there is looseness, it should be tightened in a timely manner.
Regular Maintenance: Regularly inspect and maintain the key components of the filling machine, such as vulnerable parts like the double screws, seals, and filling nozzles. If wear or damage is found, they should be replaced in a timely manner to ensure the filling accuracy and prevent dripping. In addition, it is also necessary to inspect and maintain the pneumatic components, electrical components, etc., to ensure their stable performance.
