Don’t think of stove diameter as a ranking of production capacity. When comparing 300mm and 400mm commercial induction cookers, you must first confirm the number of stoves, concave and flat structure, power caliber and allowed pots, and then check whether the menu and order are suitable for this set of configurations. If one of the plans is a single stove and the other is a double stove, they can be compared as a complete set of job plans, but they cannot be used to prove that just increasing the stove will improve efficiency.
The parameters on the two pages are similar, but it does not mean that the comparison conditions are consistent.
Take Fengzhida's two public pages as an example: XC-300DC-G-8T lists a 300 mm stove head, while XC-400SC-G-8T lists a 400 mm concave surface and a 430 mm flat surface. [1][2] The latter is also marked with two sets of magnetically controlled gears. The appearance of the same power figure on both pages does not eliminate the structural differences; especially the eight kilowatts on the double-cooker page, which is not further broken down into the ratings of each stove and the caliber of the whole machine when working at the same time.
Therefore, the current data cannot support the comparison of "both have 8 kilowatts, which one is stronger?" You should first obtain the formal technical description of the same model and check the rated power, power supply interface and simultaneous use restrictions of each heating zone and the complete machine. If you can't get it temporarily, you can continue to sort out the requirements, but you should not complete the electrical design based on it, or rank the performance of the two devices in advance. Insufficient data here are the boundaries of conclusions, not gaps that can be filled with experience.
The burner size is not a pot fitment chart either. The material, bottom shape, contact position, and weight of the pot are related to the equipment requirements; knowing the diameter of the concave surface alone cannot declare that it can definitely accommodate larger and heavier pots. The pots and pans used by operators on a daily basis should correspond to the model description one by one. Do not test unconfirmed combinations with power on first. Seeing that others can use similar pots does not replace this verification.
Rewrite the procurement problem into a dish task
Instead of asking "Which one is used in big stores and which one is used in small stores?", it is better to choose a high-frequency dish and write down what it goes through from order to delivery. Whether the raw materials have been packaged, whether the orders can be batched together, whether they need to be plated after the pot is taken out, and whether the pot must be changed or cleaned for the next batch will all affect the actual occupation of the position. Store area only provides spatial information and cannot answer these production questions.
For example, two orders that arrive scattered may not be suitable to be processed in one batch; tasks that require a large number of the same dishes at the same time may increase the number of loading and unloading times due to repeated batching. What is discussed here is order organization, not assertion that a certain stove is faster. The joint batch must also comply with the requirements of dish quality, processing and delivery. In order to show that the equipment is fully utilized, orders that should be completed in time cannot be delayed indefinitely.
It is more useful to create a task card for representative dishes than to apply "a few kilograms in one pot" first. Write on the card the status of the raw materials, the allowed feeding range, qualified product conditions, required operations, the latest completion time and who to hand it over to. The feeding range is governed by the applicable instructions and the confirmed dish process. This article does not provide universal weights across machine models. Different dishes cannot be treated as the same load just because they weigh the same.
Where to start timing determines what the comparison is answering
If only the heating time is counted, what is obtained is a partial performance of the process; if it is used to arrange lunch positions, it also depends on the complete occupancy of loading, unloading and restoring the next batch. It is recommended to keep two clocks at the same time: one from the time when the stove is occupied from the beginning of this batch to the time when the next batch can start, and the other from the order arrival to delivery. The former helps understand job capabilities, while the latter reflects customer waiting. The two are not interchangeable.
The following uses hypothetical numbers to illustrate the caliber. The numbers do not correspond to the actual measurements of any Fengzhida equipment. Assume that both plans complete a batch of four dishes. Plan A requires one minute of feeding, three minutes of heating, one minute of cooking, and one minute of recovery. The complete cycle is six minutes. Plan B uses one minute and five minutes, two minutes, one and five minutes, and two minutes respectively, and the cycle is seven minutes. B's heating takes one minute less, but takes up one minute more. You can't just choose one section to declare it faster.
Under ideal continuous conditions without considering waits, failures, and other constraints, the number of batches per hour can be written as "sixty minutes divided by the single batch period." The above assumptions yield A with ten batches and B with approximately 8.6 batches; this is only the average rate used for analysis. It does not mean that 0.6 complete batches can be delivered on site, nor is it the nominal production capacity of the product. If the duration of each batch is different, the qualified batches completed within the same observation window should be directly counted, and the fastest batch should not be used to replace the entire record.
Order waiting may also overturn this partial result. A Even if the kitchen space is occupied for a short period of time, if the food is packed before the start of work, customers may not receive the food earlier. The on-site record should write down which step the waiting occurs, neither counting the delay in material preparation as a heating equipment problem nor erasing it from the comparison of job plans. If staffing is different between the two scenarios, the report should explain the difference rather than imply that the same results would be obtained by simply changing the equipment.
The extra capabilities of double stoves need people and space to catch them
To compare the configurations of two sets of stoves, people, pots and containers should be added to the floor plan. Check whether the chef can turn around safely, whether there will be overlap in taking out the seasonings, whether the end of the pot can only accommodate one plate, and where the empty pot goes. The value of dual stoves in parallel depends on whether tasks can be parallelized; actions that the same person must complete continuously will not disappear automatically because of one more heating position.
No-load action inspection can reveal the conflict between the pot distance and the channel in advance, but it cannot prove that the loaded operation is equally smooth. Subsequent trial work must be carried out under the premise that the installation and use conditions have been confirmed, and must be carried out by people familiar with the position according to the prescribed actions. The record should not only include the finished product, but also include restrictions on stir-frying, inconvenience in carrying the pot, temporary waiting, and difficulty in cleaning. When a security issue arises, deal with it first and continue without collecting enough samples.
Changing dishes and handling after shifts are also selection criteria. When comparing only one-pot dishes, it is easy to miss the time required for residue disposal, pot turnover, and restoration of the work surface. If two devices require different cleaning methods, they should follow their own instructions and do not force them to use the same cleaning action to create a fair surface. What is truly fair is to use each correct method and honestly record the resulting personnel and time requirements.
Four questions that the results table must answer
First, does the target dish meet the predetermined quality requirements? The evidence is the input, process and results of the batch, not the operator saying "almost" afterwards. Nonconforming batches should be left in the records, noting which step the problem occurred at. If the feeding or operation is temporarily adjusted, the batches before and after the adjustment should be separated and cannot be mixed into an average value.
Second, can representative peak tasks be delivered on time? Answer with order timeline, completion time and reason for waiting. Third, is the position really operable? Look for conflicts between people, containers and aisles working at the same time, rather than just checking machine dimensions. Fourth, can changing dishes and cleaning after shifts be included in existing shifts? It is necessary to record the usable status after correct cleaning, not just the time when heating is stopped.
There is no need to combine these four questions into a seemingly accurate total score. The dishes are qualified but the cooking conflict has not been resolved. All conditions are met, but the cleaning is slightly slower. This is a result of a different nature. The former requires changing the layout or job arrangements first; the latter can compare long-term workload when other conditions are equivalent. Keeping the differences can better support subsequent implementation than simply choosing a "comprehensive first" one.
Procurement conclusions should be written as boundary-bound job arrangements
The final choice can explain which menu tasks a certain model is responsible for, which confirmed pots are used, how many operators are needed, and how it interfaces with the preparation and delivery ends. Only scopes that have passed corresponding verification can enter the operation arrangement. If you have not obtained the double-burner power caliber or pot adaptation information, you should clearly stop at the "candidate configuration" instead of hiding unresolved matters in the finalized procurement conclusion.
It is also important to indicate which results cannot be extrapolated: a representative dish with skilled hands does not prove the entire menu, a smooth trial does not represent all meal segments, and a comparison of plans does not prove conversely that the diameter of the burner made all the difference. Three hundred millimeters and four hundred millimeters are just search entrances; check the equipment structure, task caliber and job constraints clearly, and then the selection will have reasons for review.
