Peanut Paste Filling Machine work process

1. Preparation stage
Raw material supply:
Egg yolk sauce enters the hopper of the filling machine from the storage tank through a vacuum or pressure conveying system. The hopper is equipped with a constant temperature device (optional) to ensure stable fluidity of the sauce (preventing low-temperature solidification).

Bottle positioning:
Empty bottles enter the filling station through a conveyor belt and are accurately positioned by photoelectric sensors or mechanical baffles to ensure alignment between the filling port and the bottle port.

2. Filling stage
Quantitative extraction of piston:
The piston drive system draws back a predetermined capacity (such as 50g-500g) and extracts a certain amount of mayonnaise from the hopper.

High precision control: Adjust the piston stroke through PLC, with an error of ≤± 1% (optimized for high viscosity sauces to avoid wall residue).

Filling execution:
The piston advances forward and injects the sauce into the bottle through a food grade stainless steel nozzle. The filling head is equipped with anti drip design (such as suction function) to ensure that there is no residue at the bottle mouth.

Adaptive mode: For different bottle mouth sizes, the nozzle can automatically lift or switch the tilt angle to prevent splashing.

3. Cleaning and maintenance phase
Online Cleaning (CIP):
After production is completed, the CIP system is activated to circulate high-pressure water flow and food grade cleaning agents to flush the hopper, piston chamber, and pipelines, avoiding bacterial growth caused by sauce residue.

Key component maintenance:

Regularly disassemble the piston sealing ring to check for wear;

Lubricate the guide rails and transmission components to ensure smooth operation.

FAQ:

Q1: Is this filling machine specifically designed for peanut butter? Can you handle other high viscosity sauces?
A: yes! This equipment is specially optimized for peanut butter, sesame butter, chocolate butter and other high viscosity fluids (viscosity range 1000-50000cP). It supports hot filling (thermostatic system is required) or normal temperature filling, and can also be used in cross-border scenes such as paste cosmetics (such as face cream).

Q2: Does it support different packaging types (bottled, canned, flexible packaging)?
A: support! Suitable for glass bottles, PET bottles, tin cans, aluminum foil bags, etc. The filling nozzle can be customized (flat mouth, pointed mouth, rotating type), and the diameter of the bottle mouth is compatible with 15-100mm. Customized sample fixtures are required for irregular packaging.

Q3: What is the filling accuracy? How to avoid sauce hanging on the wall or residue?
A: Adopting servo motor+piston quantitative technology, with an error of ≤± 0.5%;
The filling head is equipped with anti drip and anti suction function, and the inner wall of the nozzle is polished to reduce wall residue.

Q4: Peanut butter is prone to clogging pipelines. How can equipment solve this problem?
A: Design Highlights:

The hopper and conveying pipeline are equipped with electrically heated insulation layer (adjustable temperature to prevent the sauce from solidifying);

Large caliber stainless steel piston pump (minimum passing particle diameter ≤ 3mm);

Support one click start of online cleaning (CIP) function to quickly remove residues.

Q5: Does the equipment comply with food grade production standards?
A: Strictly follow food safety requirements:

The parts that come into contact with the sauce are made of 316L stainless steel or food grade silicone;

Open structure design, easy to disassemble and clean;

Provide CE, FDA and other certifications (optional)
