Batch number is the batch number, the same batch of products can be used to manage a batch, the same processing of a batch of the same batch of parts can yo a lot to manage; Serial number is used to manage a single product.
The batch number mentioned in the Food and drug industry management is batch, because food and drug safety depends mainly on raw materials and production processes. The same batch of produced products usually need to be shipped as finished product after multiple packaging. Each batch of packaging can be managed with lot, but in the event of quality problems, it is necessary to use the same raw materials and production of the same product recall, this is the same batch.
For example, the brewing industry may use a large fermentation pond to ferment, this time the fermentation produces all the wine should use the same batch, and this batch of wine may be multiple bottles, and then sold, each bottle of the product can be used in the same lot, for the very wine and even use serial to manage. When a lot/serial product is found to have quality problems, it should recall the entire batch product to ensure that there will be no quality unqualified products in the market.
