Title:
メチオニンの気流搬送方法
Document Type and Number:
Japanese Patent JP6985382
Kind Code:
B2
Abstract:
The present invention provides a method of airflow transportation of methionine that can minimize the crushing of methionine, which is characterized in that when methionine is transported as airflow using carrier gas, the flow state of methionine is a low concentration floating flow type, and the mixing ratio of methionine and carrier gas is in the range of 4 to 10 kg -methionine / kg -carrier gas. In the method of airflow transportation of methionine of the present invention, if the D50 of methionine is in the range of 150 to 425 µm, the increase rate of the fine powder can be suppressed to 1.5% or less by maintaining the mixing ratio at 4 to 10 kg -methionine / kg -carrier gas, and can be suppressed to 1 % or less by maintaining the mixing ratio at 5 to 10 kg -methionine / kg -carrier gas.
