The quickest way to ferment tofu residue usually involves the use of highly effective microbial agents, such as EM bacteria, and the optimization of fermentation conditions, such as suitable humidity and temperature. Here are the detailed fermentation steps:
1.Prepare the ingredients: First of all, you need to prepare fresh tofu residue and eminoculum.
2.Adjust the humidity: adjust the moisture of the tofu residue to 60-65%, that is, the tofu residue can form a lump by hand, but it will not drip water. Proper humidity is conducive to the growth of microorganisms and the fermentation process.
3.Mix the EM agent: Dilute the EM agent according to the proportion on the instructions, and then sprinkle it evenly on the tofu residue to ensure that the tofu residue is fully mixed with the fungus agent.
4.Accumulation and fermentation: Pile the treated tofu residue in a clean cement floor or fermentation tank, and the height of the accumulation should not exceed 15 meters for ventilation and temperature control.
5.Temperature control: The fermentation process needs to maintain a suitable temperature, usually around 30 °C. In the summer, the temperature inside the fermentation pile may rise, and it is necessary to turn the pile regularly to dissipate heat to avoid excessive temperature inhibiting microbial activity or causing the tofu residue to deteriorate.
6.Turning the pile regularly: In order to ensure the uniform fermentation and oxygen supply of the tofu residue, it is usually necessary to turn the tofu residue every 2-3 days.
7.Fermentation completed: Tofu residue fermented with EM bacteria is usually fermented within 7-10 days. Fermented tofu residue will have a sour flavor and a fluffy texture.
After the fermentation, the tofu residue can be used as organic fertilizer, or as feed to feed livestock, such as pigs, cattle, sheep, etc. However, it is important to note that tofu residue generates heat during the fermentation process, so it is important to monitor the pile temperature to avoid overheating and fermentation failure. In addition, after fermentation, tofu residue can be used as a protein feed, but because it contains some anti-nutritional factors, it needs to be added to the feed of livestock in an appropriate amount.
