For a new tank that has not yet been fermented, it is difficult to find a way to measure the residue. The company can determine a substance that can be accurately detected according to the actual detection ability, and then spray it on different positions on the inner surface of the fermentation tank.
After cleaning, use the rubbing sampling method to detect the residue, and the residue is one thousandth Such indicators are the limit.
For the residue of cleaning agent, take samples at different moments when the last wash tank water is released, and test them one by one. Each test result is required to meet the requirements.
If the cleaning agent is water, this step can be omitted.
