Abstract：Pig blood power are prepared from pig blood adopting the method of spray drying in the experiment.The affection on product’s quality are researched through the single factor experiment,the factors include the attenuant multiple of blood,the temperature of incoming air and the velocity of feed-in.The best technical parameter is confirmed through determining the crude protein，the crude ash, the water activity and the sense organ index sign. The results indicates that the best quality of pig blood power while the attenuant multiple of blood is 0.67,the temperature of incoming air is 160℃ and the velocity of feed-in is 0.167 ml/s.
