A wider noodle sheet can increase theoretical mass flow, but it also multiplies the load on mixing, resting, cutting, rod handling, drying, finishing, weighing, packaging, utilities, and the building. If those sections do not expand together, the wider roller becomes an expensive upstream buffer.
Shangbaotai publishes three reference dry noodle configurations: 500 mm roller width at 1.5 tonnes per hour, 1,000 mm at 2.5 tonnes per hour, and 1,600 mm at 4 tonnes per hour. These figures provide a useful starting point for capacity discussion. They are not enough to select a line without confirming the product and the basis of the tonne-per-hour values.
Wide roller and sheeting section of a dry noodle line.
Roller width determines how much dough sheet can pass through a stand at a given thickness and speed. Wider equipment also affects shaft stiffness, roll deflection, drive load, frame design, alignment, access, cutter width, and the way the sheet is divided into noodle lanes.
Shangbaotai states that its 1,600 mm dry noodle system divides one sheet into two for stable production. Ask the engineering team to explain the sheet path, lane division, drive synchronization, trim handling, and how thickness uniformity is checked across width.
Capacity is still a function of sheet thickness, speed, formulation, yield, moisture, product dimensions, and accepted quality. Require both wet process mass and final dry output, with the measurement point stated.
The 500 mm option may fit a plant with lower initial demand, fewer packaging lanes, restricted space, or a staged investment plan. The buyer should evaluate efficiency at the planned load, not assume that a smaller line is automatically simpler. Dryer residence time, automatic rod handling, and packaging can still dominate the layout.
Ask whether the 1.5 t/h figure is based on wet noodle input or dried finished product, which moisture and dimensions apply, and how many operators and packaging machines are assumed.
The 1,000 mm option sits between the published small and large references. It may suit a factory that needs more output but cannot justify the building, utility, or end-of-line scale of the 1,600 mm system.
The capacity ratio is not linear with width in the published table: doubling width from 500 to 1,000 mm increases the listed throughput from 1.5 to 2.5 t/h, not to 3 t/h. This reinforces that configuration, product, speed, and downstream process affect the result. Do not extrapolate capacity from width alone.
The 1,600 mm line is the highest published reference. Shangbaotai also states that its automatic finishing system prevents rod blockage and supplies rods at 24 per minute. A 4 t/h project must verify that the dryer, rod transfers, cutting, weighing, packaging, and warehouse remove the product continuously.
Wider equipment requires careful building and maintenance planning. Confirm transport dimensions, installation openings, foundations, platforms, roll access, lifting points, and the space required to remove cutters and rolls.
Calculate annual good tonnes, planned operating days, shifts, hours, sanitation, maintenance, changeovers, and efficiency. Then define average, peak, and design output. Separate wet and dry mass.
Design dry output = annual saleable dry tonnes / scheduled operating hours / planning efficiency
Planning efficiency is a factory assumption. The supplier’s performance guarantee must have its own stated test basis. If the plant produces several lengths, strand sizes, pack weights, or recipes, include a SKU matrix because the governing product may not be the highest-volume one.
Wider sheeting needs enough mixed and rested dough delivered uniformly. Check flour supply, liquid preparation, mixer cycle, buffer volume, first-in-first-out residence, and dough feeding across the full working width.
If several batch mixers feed one wide line, define sequence and control. If continuous mixing is proposed, verify its stable range and transition behavior. The 1,600 mm roller cannot compensate for starvation or uneven feed.
Roll reductions, sheet tension, edge guidance, and cutter condition must remain consistent across width. Ask how the line monitors pressure or load. Shangbaotai’s dry-line page states that rolling pressure is monitored to help prevent metal from entering rollers and slitters; it also mentions a 100 GS magnetic rod. Confirm current design and protection details in the proposal.
Dry noodle equipment must be balanced with dryer capacity.
For dry noodles, the dryer often controls good output. It must hold the mass flow for the required time while managing temperature, humidity, and airflow. A wider sheet usually means more strands or rods per time, not permission to shorten the validated profile.
Request wet load, moisture removed per hour, residence range, loading per rod, rod spacing, zone conditions, and product distribution. Test moisture across the dryer, not only at one outlet point.
Shangbaotai states that medium- and low-temperature drying is used and that time can be customized. Specific temperature, time, energy, and dimensions need confirmation for the selected width and product.
Finishing equipment downstream of noodle drying.
Rod supply, hanging, transfer, unloading, cutting, and rod return must operate at the required rhythm. A small jam rate at high output can create frequent stops. Review sensors, accumulation, manual recovery, access, rod inspection, and the effect of a downstream stop.
For the 1,600 mm reference, confirm how “one divides into two” interacts with rod length and downstream finishing. Ask whether two product streams remain separate through drying and packing or rejoin later.
Convert tonnes per hour into packs per minute for every pack weight:
Packs per minute = dry kg/h / pack kg / 60
At 4,000 kg/h, a 500 g pack would represent about 133 packs per minute before losses; a 1 kg pack would represent about 67. These are arithmetic illustrations, not Shangbaotai guarantees. Add weighing, bundle formation, film changes, rejects, case packing, and maintenance when selecting packers.
Several parallel packaging lanes may be required. Compare one high-speed line with multiple smaller units based on redundancy, changeovers, floor space, labor, and control complexity.
Ask for connected and operating electricity, steam or heating medium, water, compressed air, ventilation, and drainage for each width. Wider lines may change both process demand and utility distribution. Provide ambient conditions and destination-country requirements.
The layout should show receiving, flour storage, process flow, dryer, finishing, packaging, warehouse, utilities, hygiene zones, maintenance aisles, and emergency access. A capacity decision that ignores building cost is incomplete.
Compare four approaches: start with 500 mm and add a second line; start with 1,000 mm and reserve expansion; install 1,600 mm at partial load; or phase packaging and utilities around a larger process line. Each has different redundancy and shutdown risk.
Two smaller lines can provide product separation and maintenance resilience but may duplicate labor and equipment. One large line can concentrate capital and simplify flow but creates a larger single point of failure. Use forecast, SKU mix, maintenance capability, and site space to decide.
Specify the test product, incoming and final moisture, strand dimensions, length, output measurement point, run duration, utility conditions, moisture uniformity, breakage, cooking tests, and accepted output. Include each downstream section through packaging if the contract guarantees packaged product.
Do not accept a capacity demonstration with a different pack weight or a wetter final product unless an agreed conversion is documented.
Typical errors include assuming capacity scales directly with width, choosing 1,600 mm from a five-year forecast while operating far below an efficient range, forgetting dryer residence time, and sizing packers from nominal speed. Buyers also omit rod logistics, building openings, roll maintenance access, and the mass basis of “t/h.”
Confirm that the published 500/1,000/1,600 mm and 1.5/2.5/4 t/h relationships remain current. Ask what product, moisture, and measurement point define each output; which equipment differs; how drying and rod handling scale; what utilities and dimensions apply; and which packaging concepts are available.
Submit target dry tonnes, SKU matrix, pack weights, shifts, site utilities, and a layout. Ask for a line balance from flour input to accepted packs.
No. The published Shangbaotai data is not linear, and actual capacity also depends on speed, product, moisture, drying, and downstream equipment.
The best width matches validated demand, SKU mix, dryer and packaging capacity, utilities, building, labor, and expansion plan.
The public table does not state the basis. Confirm the measurement point, moisture, product, and accepted-output definition in the proposal.
That is configuration-specific. Ask for minimum stable rate, product quality at partial load, utility behavior, and recommended production campaigns.
Convert dry kg/h into packs per minute for each pack weight, then apply demonstrated operating speed, changeovers, rejects, and redundancy strategy.
Rod supply and transfer determine how noodles enter, move through, and leave hanging-drying sections. Inadequate handling can stop the entire line.
Issue an RFQ that states saleable dry output and product conditions, then ask Shangbaotai to recommend the working width and return a full line balance. Evaluate the 500, 1,000, and 1,600 mm options as factory systems, not as three isolated rollers.
Review the relevant product pages for continuous mixer, slitter. Model data, options, and supply boundaries should be confirmed in the project proposal.
Send product samples or drawings, recipe ranges that can be shared, required accepted output, package formats, available utilities, a dimensioned factory plan, and the intended commissioning schedule. Ask the supplier to return a process flow, equipment boundary, utility schedule, layout, trial plan, and acceptance basis.
Contact Shangbaotai to discuss a project-specific configuration.
