LM-B4-80L High Speed Large Paper Bowl Machine
LM-B4-80L large paper bowl machine: 150-185 mm diameter, max height 136 mm, 70-80 pcs/min, 29 kW, 8,500 kg.
Quick Answer: What Is The LM-B4-80L?
The LM-B4-80L is a high speed large paper bowl machine that forms paper bowls for noodles, soup and salads at 70-80 pcs/min. It is powered by 29 kW, needs 0.8 m³/min of compressed air, and ships in 30-35 working days. It is built for instant noodle, soup and ready-meal bowl producers.
The LM-B4-80L is the large bowl machine of the high speed family. It covers bowl diameters from 150 mm to 185 mm with a maximum height of 136 mm, which is the family size and sharing pack range that standard bowl machines cannot reach.
It runs on the same double cam shaft platform as the cup and standard bowl machines, so spare parts, tooling logic and operator training stay common across the whole line.
What Is A High Speed Large Paper Bowl Machine?
A high speed large paper bowl machine is an automatic forming machine that turns pre-printed, die-cut paper blanks into finished paper bowls in one continuous cycle: the blank is fed, the body is formed and side-sealed, a bottom disc is inserted and heat-sealed, the rim is curled, and finished pieces are counted and stacked.
Unlike semi-automatic equipment, which moves cups between stations by hand, a fully automatic machine such as the LM-B4-80L keeps every station in mechanical phase. That is why it can hold 70-80 pcs/min with a single operator, and why output stays consistent across long shifts for instant noodle, soup and ready-meal bowl producers.
Feature:
- 150-185 mm bowl diameter – family size and sharing format
- Max bowl height 136 mm – deep bowls for salads and hot meals
- 70-80 pcs/min – real high speed on a large format bowl
- Double cam shaft platform – same drive concept as the LM-C4 cup series
- Heavy 8,500 kg frame – stable with large blanks
- Common tooling interface – simplifies maintenance across models
Application:
The LM-B4-80L serves converters producing large format bowls:
- Family size salad bowls for supermarket chains
- Large hot meal bowls for delivery platforms
- Sharing packs for snacks and fruit
- Big soup bowls for catering and events
With 70-80 pcs/min on a 185 mm bowl, one LM-B4-80L can replace two smaller bowl lines in a factory that mainly runs large formats.
Machine Parameters:
| Item | Specification |

| Bowl Size | Diameter 150-185 mm, max height 136 mm |
| Production Speed | 70-80 pcs/min |
| Power Supply | 380 V / 29 kW, 50 Hz |

| Net Weight | 8,500 kg |
| Dimension | L3600 × W1720 × H1962 mm |
How Does The LM-B4-80L Work?
The LM-B4-80L runs a continuous, fully automatic cycle. One operator loads material and monitors the panel; the stations below run in sequence:
- Blank feeding: Pre-printed, die-cut fan-shaped blanks are loaded into the magazine and fed one by one.
- Body forming: The blank wraps around the mandrel and the side seam is sealed with heat.
- Bottom insertion: A bottom disc is punched from the paper roll and placed into the body.
- Bottom sealing: The bottom heater bonds and knurls the base so the container is leak-proof.
- Rim curling: The top rim is rolled outward for a smooth drinking edge and a tight lid fit.
- Counting and stacking: Finished pieces are counted automatically and stacked into sleeves.
Main Machine Features:
- Large Format Cam Platform: the cam drive is sized for 185 mm blanks, so forming pressure stays even on the widest bowls.
- Deep Draw Height: 136 mm deep bowls keep their wall shape without wrinkling.
- 8,500 kg Frame: mass is what keeps a large bowl line quiet and accurate at speed.
- Shared Platform With Cup Series: one maintenance skill set covers the whole high speed family.
- Stable 70-80 pcs/min: realistic sustained speed on large formats, not a peak number measured for one minute.
What Can The LM-B4-80L Produce?
| Product | Typical Size | End Use |
| Family salad bowl | 150-185 mm top diameter | Supermarket chains |
| Large hot meal bowl | 150-180 mm top diameter | Delivery platforms, catering |
| Sharing snack bowl | 160-185 mm top diameter | Popcorn, nuts, fruit |
| Event soup bowl | 150-175 mm top diameter | Canteens, airlines |
Output Planning: What Can You Expect Per Shift?
Use these numbers to size the machine against your order book:
| Production Window | Running Time | Output At Rated Speed |
| Per hour | 60 min | 4,800 bowls |
| Per 10-hour shift | 10 h | 48,000 bowls |
| Per day (2 shifts) | 20 h | 96,000 bowls |
| Per month (26 days, 2 shifts) | 520 h | 2,496,000 bowls |
Figures are calculated at the rated top speed of 70-80 pcs/min and assume steady material supply and normal changeover time. Running smaller sizes or heavier board will sit at the lower end of the range.
Is The LM-B4-80L The Right Machine For Your Factory?
Choose the LM-B4-80L if:
- You need 70-80 pcs/min of steady output and want one machine to cover bowls 150-185 mm in diameter and up to 136 mm in height.
- You supply instant noodle, soup and ready-meal bowl producers and need consistent, leak-proof quality on every batch.
- You want one high speed line instead of two medium speed machines, so floor space and labour stay at one machine.
- You plan to run two shifts and need the machine to hold tolerance over years, not weeks.
Consider a different model if:
- Your orders are still small and seasonal: a lower-output model keeps your capital cost down.
- You only need one fixed size today: a dedicated single-size machine is cheaper than a wide size window.
- Your main problem is defect rate rather than speed: add an inspection machine before buying more forming capacity.
Send us your container sizes, board specification and target output per month. Our engineers will size the right model and confirm the tooling before you order.
