Automatic Full-line Filling Production Line Special for Particle-containing Chili Oil

Product Details
Chili oil is a typical high-flavor seasoning oil with suspended solids. Chili fragments and chili seeds are highly prone to precipitation and valve clogging, making ordinary edible oil filling machines easily plagued by industry-wide pain points such as uneven particle distribution, material jamming and flow interruption, as well as chili oil residue adhering to bottle walls. This fully automatic filling production line, custom-built exclusively for chili oil, features dedicated anti-precipitation and anti-clogging optimizations across the entire process from material homogenization to filling. It not only ensures uniform distribution of chili fragments and spice particles in every single bottle, but also prevents long-term adhesion of chili oil pigments to the inner pipeline walls that could lead to bacterial growth, fully meeting the stringent hygiene requirements for seasoned food products.

The large-capacity mixing hopper of the equipment adopts a low-speed spiral mixing structure, which keeps chili fragments and spices evenly suspended throughout the process without sedimentation and caking at the bottom, fundamentally eliminating the quality issue of inconsistent particle content from bottle to bottle. The filling head is equipped with a custom large-channel anti-clogging valve, whose discharge caliber is more than twice that of ordinary filling machines. Even compound chili oil containing whole chili peppers and Sichuan peppercorns can pass through smoothly without valve jamming, preventing flow interruption during filling and underfilled/empty bottles. An integrated oil collecting pan is installed at the bottom of the filling station, where residual dripping oil automatically flows back for recycling. This keeps the workshop floor free of oil stains, reduces material waste, and avoids massive loss of high-value flavor chili oil.

All components of the entire machine that come into contact with chili oil undergo mirror polishing and non-stick coating treatment, so that chili oil pigments will not adhere to the inner tube walls for long. The quick-release design enables fast disassembly and cleaning by hand without tools, and an optional CIP (Clean-in-Place) module is available to complete full-pipeline disinfection without disassembling the machine, completely eliminating cross-flavor contamination between different batches and different flavors of chili oil. The intelligent PLC system can store hundreds of sets of production parameters for different bottle types and different chili oil formulas. When switching products, model changeover and commissioning can be completed within 15 minutes, significantly improving the production efficiency for multiple SKUs. The entire line can flexibly adjust the sequence of stations according to the workshop layout of overseas customers, enabling rapid implementation without large-scale renovation of existing factories, thus building a fully closed-loop automated production chain from empty bottles to finished product cartoning.

What Specifications Can We Customize for Overseas Buyers?
In response to the production needs of seasoning food-producing regions worldwide, we provide full-scenario flexible customization services, with core customization directions covering four major categories:

‌Customized Material-Specific Adaptation‌: For compound chili oil and high-viscosity hot pot base oil containing large amounts of chili fragments and spices, we customize ultra-large-diameter filling valves, paired with a multi-stage homogenizing and mixing system. The maximum allowable diameter of passing particles can reach 12mm, with zero material jamming and zero valve clogging throughout the process.

‌Customized Production Capacity and Containers‌: Based on the dimensions of the mainstream local seasoning oil bottles and pails of customers, we customize exclusive positioning fixtures and filling strokes. The number of filling heads can be expanded from 2 heads to 12 heads as required, with production capacity ranging from 1,200 bottles per hour to 3,200 pails per hour. This precisely matches the needs of entities ranging from small seasoning workshops to large compound seasoning groups.

‌Customized Regional Regulatory Compliance‌: For customers in different regions such as Southeast Asia, Europe and America, we upgrade the food-grade material of contact components that corresponds to local standards, provide supporting HALAL certification and FDA food contact compliance documents, and optionally equip with aseptic filling and full-machine anti-corrosion modules to fully meet the local regulatory requirements for seasoning food.

‌Customized Localized Implementation‌: The equipment adapts to the industrial voltage standards of different countries, has a built-in multi-language operation interface, and supports direct connection to customers' existing third-party capping and labeling equipment, enabling rapid access without modifying the original production line. A remote operation and maintenance module is also available, with an overseas technical team providing 24/7 online rapid troubleshooting for equipment faults.

Guide to Calculating Machine Capacity for Different Production Output Requirements
With this three-step calculation method, you can accurately determine the equipment specifications suitable for your project, avoiding waste caused by excess capacity or delayed order delivery due to insufficient capacity:
First, Lock the Basic Machine Model Tier

Daily output of less than 5,000 bottles (for scenarios such as small seasoning workshops, specialty flavor chili oil brands, and small-batch cross-border OEM processing): Choose a basic anti-clogging model with 2-4 filling heads, which delivers an output of 1,200-2,500 bottles per hour for 1L specifications. It features low procurement cost, and the entire line can be operated by only 2 workers, fully satisfying the production demands in the initial stage of business.

Daily output of 5,000 to 70,000 bottles (for scenarios such as medium-sized seasoning factories and mass production of regional chili oil brands): Choose a main servo-driven model with 6-8 filling heads, which delivers an output of 3,000-10,000 bottles per hour for 1L specifications. With a stable filling error within ±0.8% during long-term operation and uniform particle distribution, it is the mainstream choice for most large-scale chili oil factories.

Daily output of more than 70,000 barrels (for scenarios such as large export-oriented manufacturing enterprises and bulk seasoning oil trade): Choose a high-speed interlocked model with 10-12 filling heads, which can reach an output of 2,000-3,200 barrels per hour for 5L large pail specifications. The heavy-duty transmission system supports 72 hours of continuous full-load operation, adapting to the delivery pace of large-batch export orders.

Correct Parameters According to Working Condition Characteristics
If your chili oil has a solids content exceeding 15% and a particle diameter larger than 8mm, the operating speed should be reduced by 10%-20% based on the basic theoretical capacity, so as to ensure that particles pass through the valve smoothly and the entire filling process runs stably without material jamming.

FAQ

‌Will the filling valve get clogged when filling chili oil with large chili fragments and Sichuan peppercorns?‌
Our custom large-channel anti-clogging filling valve, paired with the spiral homogenizing and mixing system, achieves a maximum allowable particle passing diameter of 12mm. There will be no valve jamming or flow interruption throughout the filling process, and the solids distribution in every bottle remains uniform and stable.

‌Will long-term adhesion of chili oil pigments in pipelines cause cross-flavor contamination and bacterial growth?‌
All parts in contact with materials have undergone mirror polishing and non-stick coating treatment, so chili oil pigments will not adhere for a long time. The quick-release design allows fast manual disassembly and cleaning, and the optional CIP (Clean-in-Place) module completely eliminates cross-flavor contamination between different flavors of chili oil.

‌How are installation, commissioning and after-sales service guaranteed for overseas customers?‌

We provide full multi-language operation manuals, high-definition equipment installation and commissioning videos, and 24/7 online remote video guidance. We can also arrange engineers to complete the full-process commissioning and operator training on site. Core components come with an extended 18-month warranty, and overseas regional spare parts warehouses can dispatch vulnerable parts quickly.

‌Is model changeover troublesome when switching between chili oils of different flavors and different solids contents?‌
The entire equipment adopts a quick-release fixture design. When switching between different bottle types and different materials, there is no need to replace the core valve components. Model changeover and commissioning can be completed in 15-25 minutes, and production can start directly by recalling the preset production parameters on the touch screen.

‌To what level can material loss be controlled during long-term mass production?‌
The equipment is equipped with an integrated residual oil collection and recycling system, with zero dripping throughout the filling process. The monthly material loss during long-term mass production can be controlled within 0.6%, far lower than the industry average loss level of 3%, which significantly reduces the waste of high-value flavor chili oil.

‌Will overflow and bottle mouth contamination occur when filling chili oil into glass bottles?‌
The equipment adopts an in-bottle-mouth filling design paired with three-stage flow rate control. The flow automatically decelerates in the later stage of filling, so even high-viscosity chili oil will not splash and overflow. The bottle mouth remains completely free of oil stains throughout the process, preventing issues such as slipping and poor adhesive bonding in subsequent capping and labeling processes.
