Batch, the difference between Lot and serial number

Batch number is the batch number, the same batch of products can be managed using a batch number, the same processing of a batch of the same 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 should be batch, as food and drug safety are largely dependent on raw materials and production processes. Products produced by the same batch usually need to be shipped as finished goods after multiple packaging. Each batch of packaging can be used lot to manage, but once the 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 fermentation produces all the wine should use the same batch, and this batch of wine may be bottled several times, and then sell, each bottle of products can be used with the same lot, for the extreme wine will even use serial to manage. When found that a lot/serial product quality problems, should recall the entire batch products in order to ensure that the market does not exist quality unqualified products.
