Chili Oil Filling Machine Selection

Based on your chili oil filling requirements (flow rate of 1-2 L/min, normal temperature and pressure, containing chili seeds, stainless steel), and combining the RSG1600 model parameters and industry application experience, the following is a technical compatibility analysis and optimization suggestions:

I. RSG1600 Core Parameter Compatibility

Flow and Pressure

This model has a nominal flow rate of 1-2 L/min, which fully matches your requirements and can stably process chili oil containing solid 

particles (chili seeds).

It is necessary to confirm whether the compressed air pressure (0.4 MPa) meets the on-site air supply conditions. Insufficient pressure may 

cause sluggish piston movement, requiring the addition of a booster.

Material and Hygiene Standards

The entire machine is constructed of stainless steel, meeting food-grade contact requirements, but the specific grade (e.g., 304 or 316L)

 must be confirmed.

It is recommended that the supplier provide a material test report to ensure that the corrosion resistance meets the requirements for

 long-term contact with chili oil.

Filling Accuracy and Range

Accuracy of ±1% (e.g., ±1g error for 100g), suitable for small packaging (e.g., 50-500ml bottles). The maximum filling capacity is 3,000 kg, 

but the balance between single-time filling volume and equipment efficiency must be considered. For large volumes, batch filling is

 recommended.

II. Optimizing Key Technologies for Filling Materials Containing Particles

Pump Structure Selection

A rotary pump is recommended:

Advantages: The rotating gear/screw creates a sealed chamber, allowing it to handle materials containing particles and high viscosity

(such as chili oil), while maintaining a stable flow rate.

Comparison: Plunger pumps may experience seal wear due to particle entrapment, requiring frequent maintenance; magnetic drive 

pumps cannot handle particles.

Alternative Solutions:

If the chili seed particle size is small (<5 mm), consider an air-operated diaphragm pump. This pump uses the vibration of the flexible

 diaphragm to achieve self-priming discharge, preventing particle entrapment.

Preventing Sedimentation and Controlling Uniformity

It is recommended to add a stirring device (such as a side-mounted stirring paddle or bottom scraper) to prevent chili seed sedimentation

 and uneven filling concentration.

The stirring speed should be adjustable (e.g., 30-100 rpm) to prevent high-speed stirring from causing seed breakage. Filling Head Design

A wide-bore filling head (inner diameter ≥ 25mm) is used to reduce the risk of chili seed clogging.

An anti-drip device (such as a pneumatic shut-off valve) is added to prevent dripping and contamination of the bottle mouth during

 shutdown.

III. RSG1600 Model Configuration Recommendations

Required Options

Hopper: Although this model does not come with a hopper by default, a 304 stainless steel hopper (capacity ≥ 50L) with a level sensor

 is required for automatic refilling.

Filter: A 20-mesh stainless steel filter is installed at the pump inlet to intercept large particles and extend pump life.

Electrical Control Upgrade

Add a PLC touch screen to enable digital adjustment of filling volume, speed, and mixing time, improving operational convenience.

Equipped with a fault alarm system that monitors parameters such as air pressure and motor current in real time, automatically

 shutting down the machine and providing notifications when an abnormality occurs.
