A fryer can maintain its displayed temperature while the noodle line still produces uneven cakes. Oil may circulate poorly, a loaded filter may restrict flow, or the cooler may deliver products too warm for the intended package. Raising fryer speed can also reduce both frying and cooling time while increasing the load on the oil-heating system.
Specify the noodle frying machine, oil circuit, filtration, and cooler around one product and throughput schedule. The purchasing boundary should extend from steamed, portioned noodles entering the fryer to accepted cooled cakes at the packaging handoff.
Use One Product and Throughput Basis
List each launch SKU with cake dimensions, shape, thickness, portion weight, strand size, and incoming moisture and temperature. Identify the target final moisture, oil content, color, texture, rehydration result, and damage limits. State when and how these properties are measured.
Give both cakes per minute and mass flow at the relevant stage. Incoming wet mass and finished cake mass are different quantities because frying removes water while oil is taken up. Do not size the heating requirement from retail pack weight alone.
A common production rate also makes the residence-time requirements visible:
| Illustrative requirement | Calculation | What it establishes |
|---|---|---|
| 300 cakes/min; 70 g per finished cake | 300 × 0.070 × 60 = 1,260 kg/h | Finished product mass before any further losses; not the wet fryer load |
| 300 cakes/min; 2 min in the effective frying path | 300 × 2 = 600 cake positions | Product inventory needed in that path at steady flow |
| 300 cakes/min; 3 min cooling exposure | 300 × 3 = 900 cake positions | Product inventory needed in the cooler at steady flow |
These are arithmetic examples, not Shangbaotai ratings or recommended treatment times. Actual layout depends on carrier pitch, lanes, product spacing, and the effective path. Specify accepted cakes after the agreed quality checks and record rejects separately.
Request the effective immersed path, conveyor or carrier speed, lane count, cake-holding arrangement, and operating range. For a constant-speed path, residence time equals effective frying length divided by product travel speed. External machine length includes areas that may not contribute to frying exposure.
Shangbaotai's continuous noodle fryer page describes three oil-injection areas with separate control and an adjustable front-to-back temperature gradient. Ask for the quoted zone arrangement, sensors, oil distribution, and control method. The public description does not establish a temperature recipe for every cake.
Develop the profile using representative steamed cakes and the required endpoint. A thicker cake, a different portion, or a change in inlet moisture can alter dehydration and heating requirements. Record product results across the fryer width as well as along the production run.
Official Shangbaotai frying-machine product image. Confirm the heating equipment, oil circuit, controls, and transfers included in the project.
Ask the supplier to calculate heat demand from product mass, incoming condition, water removal, oil makeup, and system losses. State the available heating utilities and their conditions at the machine connection. Conveyor motor power is not the fryer's thermal capacity.
Require a diagram identifying the fryer, heater or heat exchanger, circulation pumps, filters, storage or buffer tanks where supplied, makeup, and drains. Mark the direction and expected flow in each branch. The proposal should show how heated oil reaches the product zones and returns through the selected circuit.
Check temperature stability under the actual product load and during changes in feed. Compare measured oil conditions at agreed locations rather than relying only on a controller setpoint. Confirm the heater's response and operating limits when circulation changes or product supply pauses.
Keep three quantities separate: product throughput, oil circulation flow, and fresh-oil replacement. A high circulation rate does not mean that old oil is being replaced quickly. Request total working oil inventory, anticipated product oil pickup, makeup requirements, and the procedure for managing oil condition during production and shutdown.
Shangbaotai's continuous cooking oil filter page describes coarse residue removal followed by filter-paper treatment with a published 30-micron reference. Its table lists 2.5–3.5 m³/min. Confirm the unit, tested oil conditions, and whether that flow applies to the full supplied system or a specific stage before sizing the circuit.
A filter's published flow alone does not establish performance with hot oil and accumulated noodle fines. Request the design oil temperature, viscosity basis, solids load, filter area, paper specification, and acceptable pressure or level conditions. Clarify whether the micron reference is nominal or absolute and what capture performance is demonstrated.
Identify whether all circulation oil passes through filtration or whether a side stream is treated. For a shared flow path, confirm the available flow when media are loaded. For a side stream, confirm that the treatment rate suits the expected fines generation. Mark any bypass and its intended operating conditions.
Include paper advancement or replacement, coarse-residue discharge, collection of oil carried out with waste, and the effect of servicing on production. Test the filter during those operations rather than assessing only clean-media flow at startup.
Filtration removes particles; particle removal alone does not reverse all chemical deterioration of frying oil. Agree on oil-quality tests, limits, sampling points, makeup, and replacement rules with the factory's quality team and oil supplier. Do not convert a filtration claim into a guaranteed oil-life extension or finished-product shelf life.
Show how cakes leave the fryer, drain, and transfer to the cooler. Identify any supplied surface-oil removal step and how recovered oil is handled. Cooling performance alone cannot establish a fixed reduction in final oil content.
Give the cooler's incoming product rate, temperature, cake dimensions, loading pattern, and required discharge condition. State the packaging requirement at the actual wrapper or container-loading handoff, not only at the cooler exit. Transfers and waiting time can change the condition seen by packaging.
Shangbaotai's noodle cooling machine page describes a combination of lower blowing and upper extraction. It does not publish a universal discharge temperature or airflow. Request the proposed fan arrangement, air path, residence time, and outlet-temperature basis for the intended cakes.
Provide the site's expected air temperature and humidity range, intake location, and ventilation conditions. If ambient air cannot achieve the required endpoint at peak production, ask the supplier to evaluate the necessary air treatment or additional cooling duty. Confirm air-cleanliness requirements and maintenance access rather than assuming a particular filtration grade.
Test across lanes and through representative cake sections using an agreed measurement method. Check moisture behavior, breakage, and packaging performance after cooling. A cool surface alone does not demonstrate a uniform cake temperature or a package free of later condensation.
Set one line-speed strategy from upstream cake supply through frying, draining, cooling, and packaging. If conveyors use different pitches or lane arrangements, match product rate at each transfer; identical belt speeds are not necessarily correct.
A speed increase shortens exposure in any fixed-length stage. The recipe review must therefore cover frying time, thermal load, filter operation, cooler residence time, and accepted packaging output together. Do not increase one drive and leave the other process conditions unverified.
Ask for the supplier's response to low oil level, circulation loss, abnormal temperature, filter restriction, fan failure, and downstream blockage. Define what happens to heating, incoming product, cakes already being processed, and restart approval. The technical proposal should identify the supplied detection and protective functions and the owner of each interlock.
| Specification field | Buyer input | Supplier confirmation |
|---|---|---|
| Product and output | Cake samples, inlet condition, target quality, cakes/min, and mass basis | Approved SKU range and accepted system output |
| Frying | Required product endpoint, holding format, and available heating utilities | Effective path, time range, zone profile, thermal duty, and utility demand |
| Oil circuit | Oil type, quality requirements, existing tanks or piping, and site interfaces | Flow diagram, inventory, pumps, heater, makeup, and supplied controls |
| Filtration | Expected fines, operating schedule, media constraints, and disposal arrangements | Operating flow, capture basis, pressure or level limits, and service sequence |
| Cooling | Incoming cake condition, ambient range, and packaging handoff requirements | Residence time, airflow, discharge criteria, and loaded-product trial |
| Integration | Layout, transfer details, control interfaces, and fault scenarios | Scope ownership, synchronization, alarms, product disposition, and restart plan |
Compare the full installed scope, including connecting conveyors, piping, oil handling, exhaust, access, cleaning provisions, and utilities where required. Ask suppliers to identify exclusions and interface assumptions. Separate three matching machine names from evidence that the proposed system works together.
Use the actual noodles, oil, carriers, filter media, and site-representative cooling conditions. Record inlet and outlet product mass and moisture, cake rate, frying time, measured oil temperatures, oil flow where instrumented, filter behavior, cooler discharge condition, damage, and accepted output.
Include stable production, feed variation, media servicing, speed changes, and controlled stops. Define test duration and sampling locations in advance. If improved oil quality or lower oil consumption is a purchasing objective, agree on a suitable measurement period and baseline; a short demonstration cannot establish a long-term result.
Repeat critical checks after installation with the actual heating supply, ventilation, and packaging interfaces. Approve the system against accepted cooled cakes and the agreed product tests.
Matching rate is only a starting point. Confirm product presentation, thermal duty, oil-circuit conditions, transfers, cooling endpoint, and stop logic under one trial plan.
Evaluate capture performance together with flow, media loading, oil temperature, and servicing. A restrictive filter in a shared circuit can affect circulation, so both particle removal and hydraulic performance require verification.
No. Circulation moves existing oil around the system. Fresh-oil replacement depends on oil leaving the working inventory and being replenished. Specify both on clearly defined bases.
Use the requirement established for the actual product and packaging process. Confirm the measurement method, relevant cake locations, ambient conditions, and temperature at the packaging handoff.
Cooling does not replace the required frying treatment. Approve the frying endpoint first, then verify that cooling preserves the cake and prepares it for the next operation.
Send cake samples, dimensions, incoming moisture, oil type, required output, product-quality targets, utilities, ambient conditions, and the line layout through Shangbaotai's inquiry page. Request a common process schedule, oil-circuit diagram, filter operating basis, cooling specification, and integrated test plan. Use those documents to confirm that all three sections support the same product and production target.
