The finished product of the organic fertilizer dryer is fine in particle, and the dried product can be used as a culture medium for planting edible mushroom agaricus bisporus and can also be sold as feed for breeding turtles, fish, snails, chickens, ducks and the like.

When the existing organic fertilizer dryer dries animal excrement, ammonia gas can be generated, and the ammonia is colorless and has strong pungent odor and great toxicity to human bodies due to the influence of the ammonia on the human physiology. Chronic ammonia poisoning can cause chronic tracheitis, emphysema and other respiratory system diseases, and acute ammonia poisoning is reflected in persistent cough, breath holding and the like.
