operation method of fermentation treatment
swill collected from canteens, restaurants and factories, swill mainly made of rice (more than 51% of rice), is first poured on the ground for manual cleaning (foreign bodies such as toothpicks, bone spurs, glass, etc.), with a packet of Vigor 99 starter and roughage degrading agent, and 411 kg of swill. You don't need to add corn when the rice exceeds 71%), 31 ~ 41 kg of soybean meal (rapeseed meal, cotton rapeseed meal and peanut bran can be used, the specific dosage is up to you, if the cheap rapeseed meal can be added a little more), 1 kg of salt, 41 ~ 111 kg of rice bran or whole bran or straw powder (rice bran, whole bran or straw powder, etc.) are used to adjust the water content of swill, and the dosage is not absolute. See that there is a small amount of water dripping or printed in the hand seam, and straw powder can also be used instead, such as peanut straw and peanut shell powder. If the swill you collect is dry, you don't need to add bran or straw powder).
Fill the container as much as possible, leaving no air in it (this is to isolate the air, keep it anaerobic, prevent harmful bacteria from growing and breeding by using oxygen in the air, and kill all kinds of harmful bacteria that come with swill), then cover it with plastic film, tie it firmly with rubber rope, without strict sealing, and leave a little air to prevent excessive expansion or even explosion caused by a large amount of gas generated during fermentation. For fermentation, as long as the fermentation lasts for 2-7 days (depending on the weather, a lot of ingredients of rapeseed meal are added, so that the fermentation time is longer to completely detoxify rapeseed meal), at first, some bubbles appear in the material, which is the result of normal fermentation, and later, the acidity is increased to produce some koji flavor, which can be fed to pigs.
