The invention discloses a humidifying process method for reducing unpolished rice
cracking in GABA rice production, and relates to the technical field of agricultural
product processing. The method comprises the following steps: step 1, carrying out
impurity cleaning and primary selection on
raw material brown rice, and then carrying out grading and fine selection; step 2, adding the graded and selected
brown rice into a
fluidized bed, and carrying out water mist
airflow fluidization humidification on the
brown rice; 3, after the water mist
airflow fluidization humidification treatment of the brown rice, gap
fluidization spraying humidification of the brown rice is carried out; and step 4, performing disinfection,
germination and
drying treatment to obtain GABA brown rice, and performing
grinding processing to obtain the GABA rice. Compared with a common soaking method humidification process, the method has the advantages that water mist and spraying two-section progressive segmented humidification is adopted, water mist humidification is adopted in the first stage, the humidification speed is low, spraying humidification is adopted in the second stage, the humidification speed is increased, the progressive humidification conforms to the
moisture mass transfer rule of the brown rice,
internal stress of the brown rice is reduced, and therefore the probability that the brown rice breaks down is reduced.
