Customer Case: A High-Cost Filling Line Became Underused—Why This Brewery Added 4 Compact Machines
A filling line can deliver reliable performance and still become an underused investment when the business around it changes.
Before working with Naquan Filling, this customer had already invested heavily in a dedicated filling line supplied by another equipment provider. The entire packaging setup was planned around one primary product, a fixed container format, and relatively large production runs.
At the time, the equipment matched the customer’s production requirements. But the business later changed.
Demand shifted toward multiple can formats, smaller production runs, pilot batches, seasonal releases, and customized cans. Although the existing line could still operate as designed, its fixed configuration and more complex startup and changeover process made it less efficient for small, fragmented orders.
The issue was not equipment quality. The issue was the growing mismatch between a fixed production system and a more flexible business model.
Why Did the Customer Choose 4 Compact Canning Machines?
The short answer is flexibility. The customer operated craft beer locations in both Shanghai and Shenzhen. Instead of relying entirely on one centralized filling line, it needed a system that could support smaller batches closer to each point of sale.
Naquan Filling recommended a distributed production model using four compact TRP1-1 filling and sealing machines:
- Two machines for the Shanghai locations
- Two machines for the Shenzhen locations
This arrangement allowed the customer to produce customized cans, seasonal products, pilot batches, and limited releases without waiting to accumulate enough volume for a large production run.
The equipment strategy changed from “one line for every order” to “the right equipment for each type of order.”
Why Did the Existing Filling Line Become Underused?
When the original line was purchased from the other equipment supplier, the customer mainly produced one product in relatively large volumes.
The filling machine, supporting equipment, and production layout were all built around that operating model. It was suitable for long, standardized production runs with limited product and container changes.
As the business expanded, the order structure became more complex:
- More product varieties
- Different can formats
- Customized packaging
- Seasonal and limited releases
- Smaller and more frequent batches
- Sampling and pilot-production requirements
- Location-specific retail products
The existing line was still capable of completing its original production task. However, starting, stopping, cleaning, and changing over the system required too much time for small and fragmented orders.
Gradually, equipment utilization declined. Supporting production capacity also remained idle, while some new orders became difficult to handle efficiently.
This is a common equipment-selection challenge: a machine can have excellent specifications but still become a poor operational fit when the order structure changes.
How Did the Production Requirements Change?
| Production Factor | Original Production Model | New Business Requirements |
|---|---|---|
| Product range | One primary product | Multiple SKUs and seasonal products |
| Batch size | Large, planned production runs | Small and frequent batches |
| Container format | Fixed specification | Multiple can formats |
| Production location | Centralized production | Locations in two cities |
| Packaging schedule | Fixed production plan | On-demand production |
| Equipment priority | Output and standardization | Flexibility and utilization |
| Sales model | Regular volume production | Retail, customized, and limited releases |
The customer did not need another large beer canning line. It needed equipment that could start efficiently for smaller batches and be deployed closer to local demand.
How Naquan Filling Developed a More Flexible Production Plan
When the customer approached Naquan Filling, we did not immediately recommend another high-capacity line.
Instead, our team evaluated:
- The customer’s current order structure
- Typical production batch sizes
- Number of product SKUs
- Can format requirements
- Available production space
- Production frequency
- Multi-location retail model
- Future product-development plans
Based on these requirements, Naquan Filling recommended the TRP1-1 mobile filling and sealing machine.
The customer purchased four TRP1-1 systems in stages and deployed two machines in Shanghai and two in Shenzhen.
The compact machines were assigned to small, varied, and time-sensitive orders instead of forcing every order onto the existing dedicated line.
Why Was the TRP1-1 Selected?
The TRP1-1 combines counter-pressure filling and can seaming in a compact unit designed for small-batch beverage production.
The TRP1-1C configuration provides a rated production capacity of approximately 200–300 cans per hour. Its machine dimensions are approximately 1100 × 950 × 1700 mm, giving it a footprint of about one square meter.
This makes it suitable for production environments where floor space is limited, including:
- Craft brewery packaging areas
- Taprooms
- Brewpubs
- Pilot breweries
- Small beverage production rooms
- Multi-location retail businesses
- Customized beverage production
The production process can include:
- Automatic can feeding
- Can rinsing
- Air blowing
- CO₂ purging
- Counter-pressure filling
- Controlled foaming
- Automatic lid placement
- Double seaming
- External can rinsing
- CIP cleaning
Counter-pressure filling helps manage foam and retain carbonation when filling beer and other carbonated beverages. CO₂ purging helps remove air from the empty can before filling, limiting oxygen exposure and supporting product freshness.
Actual can compatibility is confirmed according to the customer’s can diameter, height, lid specification, and production requirements before equipment manufacturing.
What Changed After the 4 Machines Were Deployed?
After operating the distributed system, the customer reported that the solution matched its current business rhythm more closely.
1. More Flexible Small-Batch Production
Customized cans, holiday releases, pilot batches, and seasonal products could be scheduled without waiting to accumulate enough volume for a long production run.
This gave the customer more flexibility to support:
- New product launches
- Holiday promotions
- Local events
- Customized gift cans
- Pilot batches
- Market testing
- Short-run retail orders
The equipment could follow the order schedule instead of forcing every order to follow the requirements of a large production line.
2. Healthier Finished-Goods Inventory
Local, on-demand canning reduced the need to produce and store large quantities of finished products in advance.
This helped the customer:
- Reduce finished-goods inventory
- Limit working capital tied up in packaged beer
- Avoid overproducing slow-moving SKUs
- Respond more closely to local sales demand
- Shorten the time between packaging and retail sale
- Reduce the risk of flavor decline caused by unnecessary storage
For a craft beer business, packaging flexibility and inventory turnover can be more valuable than maximum theoretical line speed.
3. Faster Local Product Availability
Previously, centralized production required finished products to be transported between cities.
With compact filling and sealing machines deployed in both Shanghai and Shenzhen, smaller batches could be produced closer to the local retail locations.
This helped shorten the route from production to shelf and reduced dependence on cross-city transportation for every customized or limited release. Products designed for a specific location or promotional event could also be prepared more quickly.
Does This Mean the Original Filling Line Was a Bad Machine?
No.
The existing line had been selected for a different production model. It was designed around a fixed product, a standardized container, and relatively large production runs.
The business changed faster than the equipment strategy.
The lesson from this case is not that large or dedicated filling lines are unsuitable. The lesson is that equipment should be selected according to actual order structure, production frequency, container variety, and future business plans.
A high-capacity line can be the correct choice for stable volume production. A compact canning machine can be the better choice for small batches, frequent product changes, or distributed production.
Why Equipment Utilization Matters More Than Maximum Speed
A high-speed can filling and sealing machine makes sense when a brewery has:
- Stable and predictable production volumes
- Long production runs
- A limited number of container formats
- Sufficient production space
- Established wholesale or distributor demand
- Enough orders to maintain high equipment utilization
A compact canning machine may be more suitable when the business has:
- Multiple SKUs
- Frequent product changes
- Pilot or trial batches
- Seasonal releases
- Customized packaging
- Taproom-only products
- Limited production space
- Multiple retail locations
- Unpredictable order volumes
The best filling machine is not necessarily the machine with the highest rated output. It is the machine that can operate efficiently within the customer’s real production schedule.
Naquan Filling’s can filling and sealing machine capacity guide provides additional guidance for selecting equipment from approximately 100 to 8,000 cans per hour.
Two Practical Equipment-Selection Lessons
1. Avoid Overcommitting to Fixed-Format Equipment During a Period of Change
Dedicated filling equipment can provide strong efficiency and consistency for a stable product and container format. However, it may leave less room for future changes.
If your product range, can sizes, batch volumes, or sales channels are still evolving, consider whether the equipment provides enough flexibility for future production requirements.
Before purchasing, ask:
- How many SKUs will we produce next year?
- Will we introduce new can sizes?
- How frequently will products change?
- What is our typical production batch?
- Can the machine operate efficiently at that batch size?
- How much time will startup, cleaning, and changeover require?
- Will most orders be standard production or customized runs?
2. Consider Distributed Production for Multi-Location Businesses
Centralized production is not the only option for a brewery group, brewpub chain, or beverage company with several retail locations.
Deploying compact filling equipment at selected locations can support:
- Local production
- Faster product launches
- On-demand packaging
- Reduced finished-goods transportation
- Location-specific products
- More responsive inventory planning
- Seasonal and customized releases
The goal is not to place a machine in every store. The goal is to determine whether all production should remain centralized or whether selected products should be packaged closer to local demand.
Is a Compact Canning Machine Right for Every Brewery?
No. A compact canning machine is not intended to replace a high-capacity automatic line in every production environment.
If a brewery produces the same products continuously in large volumes, a centralized automatic beer canning line will normally provide higher output and better labor efficiency.
Compact equipment becomes more valuable when flexibility, space, batch size, product variety, and equipment utilization matter more than maximum production speed.
What Information Is Needed Before Selecting a Canning System?
To select the right can filling and sealing machine, prepare the following information:
- Beverage type: beer, cider, kombucha, soda, sparkling water, RTD, or another beverage
- Container size and lid specification
- Target cans per hour
- Typical and maximum batch size
- Product temperature
- Carbonation level
- Number of SKUs
- Changeover frequency
- Available floor space
- Number of operators
- Required rinsing, labeling, coding, and packing processes
- Expected production growth over the next two to three years
These details provide a more reliable basis for equipment selection than capacity alone.
Frequently Asked Questions
What Is a Compact Canning Machine?
A compact canning machine combines filling and sealing functions in a smaller footprint than a conventional industrial canning line. It is commonly used for small-batch beer, carbonated beverages, pilot production, taproom releases, and limited-edition products.
Is 200–300 Cans per Hour Enough for a Craft Brewery?
It can be enough for taproom sales, customized cans, pilot batches, seasonal releases, and small local orders. Breweries with stable wholesale or distributor demand may require a higher-capacity canning line.
Why Is Counter-Pressure Filling Used for Beer?
Counter-pressure filling helps retain carbonation, manage excessive foam, reduce product loss, and limit oxygen exposure during filling. It is suitable for beer, cider, sparkling water, soda, kombucha, and other carbonated beverages.
Can One Canning Machine Handle Different Can Sizes?
Some filling and sealing machines can accommodate several can sizes. However, the supported can diameter, height, lid type, and required change parts must be confirmed before purchase. Customers should provide actual container drawings or samples when evaluating compatibility.
What Is Distributed Beverage Production?
Distributed production means placing smaller production or packaging systems closer to different sales locations instead of relying entirely on one central factory. It can be useful for multi-location taprooms, brewpub groups, and beverage retailers offering local or seasonal products.
When Should a Brewery Choose a Large Automatic Canning Line?
A large automatic line is generally more suitable when the brewery has stable high-volume demand, long production runs, sufficient space, and enough orders to maintain high equipment utilization.
Can Compact Canning Equipment Be Used for Beverages Other Than Beer?
Yes. Depending on the machine configuration, compact counter-pressure filling equipment can be used for cider, kombucha, soda, sparkling water, hard seltzer, RTD beverages, and other carbonated drinks.
