The rotor rotates inside the pump body, creating multiple sealed chambers between the rotor and the pump body. When the rotor rotates to the position of the feed inlet, the sealed chamber connects with the feed inlet, and the satay sauce enters the sealed chamber under the action of pressure difference or gravity. As the rotor continues to rotate, the satay sauce in the sealed chamber is carried to the position of the discharge outlet. At this time, the sealed chamber connects with the discharge outlet, and the satay sauce is squeezed out into the packaging container.
A servo motor is used to precisely control the rotation speed and the number of rotation cycles of the rotor pump, thereby accurately controlling the filling volume of the satay sauce. This ensures that each container can be accurately filled to the set amount.
High - precision metering: Through the precise cooperation of the servo motor and the rotor pump, the filling volume can be accurately controlled. The filling accuracy can usually reach ±1% or even higher, ensuring that the weight of each bottle or bag of satay sauce is consistent.
Wide application range: It is suitable for satay sauce of various viscosities, including high - viscosity satay sauce and satay sauce containing particles, ensuring smooth and accurate filling.
Hygiene and safety: The whole machine is usually made of high - quality stainless steel, and the parts in contact with the material are made of 304 stainless steel, meeting the GMP hygiene requirements.
Anti - dripping design: The filling nozzle is generally equipped with a pneumatic anti - dripping device, which can quickly close after filling is completed to prevent the satay sauce from dripping and stringing, keeping the filling site clean.
Easy to operate: It is equipped with an operation interface such as a color touch screen. Users can intuitively perform operations such as parameter adjustment and function testing on the touch screen, reducing the technical threshold for operators.
Easy to clean: Compared with some other filling methods, the metering method of the rotor pump is easier to clean. It can effectively avoid the residue of satay sauce, reduce the difficulty and time of cleaning, and improve the maintenance efficiency of the equipment.
Filling speed: The filling speeds of different models of filling machines vary. Generally, the filling speed of a small semi - automatic filling machine may be 10 - 30 bottles per minute, while that of a large fully automatic filling machine can reach 40 - 80 bottles per minute or even higher.
Filling accuracy: Usually, it can reach an accuracy range of ±1% to ±0.5%.
Applicable bottle or bag types: It can be compatible with packaging containers of various specifications. For example, the height of the bottle ranges from 80 - 180mm, and the width or diameter ranges from 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 is 220V.
Daily maintenance: After the daily production is completed, promptly clean the residual sauce on the surface of the filling machine to prevent the sauce from adhering to the machine after drying, which may affect the normal 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, tighten it in time.
Regular maintenance: Regularly inspect and maintain the key components of the filling machine, such as vulnerable parts like the rotor, seals, and filling nozzles. If wear or damage is found, replace them in time to ensure 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.
