Claims
- 1. In a process for producing blood powder and including the steps of: supplying blood continuously from a blood-collecting vessel to a stirrer, mixing heated live steam with blood in said stirrer to coagulate protein present in the blood as a constituent thereof, transferring partially coagulated blood constituents to a dehydrator, and employing the dehydrator to remove water from the blood constituents to form a solid product having a water content of about 30%-70%, pulverizing the solid product from the dehydrator to produce finely-divided particles having a volume of about 8 mm.sup.3, and drying the finely-divided particles within a temperature range of from about 65.degree. C. to 150.degree. C. to form a blood powder having a water content of about 15%, the improvement consisting essentially of: controlling the temperature employed during drying of the finely-divided particles to prevent the finely-divided particles from adhering to one another to form enlarged particles having reduced exposed overall surface areas, impairing ease of drying and resulting in inferior end products, said step of controlling the temperature during drying of said finely-divided particles by regulating the drying temperature as a function of water concentration present in said finely-divided particles wherein maximum effective and critical temperatures for drying particles having specific water contents are shown in FIG. 5.
- 2. A process according to claim 1, wherein the step of regulating the temperature during drying includes the step of selecting a drying temperature for particles having an water concentration of about 65% being up to about 100.degree. C. and below 120.degree. C., and the drying temperture for particles having an water concentration of about 50% being up to about 125.degree. C. and not exceeding 135.degree. C.
