(9) dry: the starch after separating twice is put into airflow counter-collision drier, adopt low-temperature airflow head-on collision drying process, bake out temperature 55 DEG C, 5 ~ 10 seconds time was 6% to moisture, obtained Radix Puerariae fine powder.
As the further scheme of the present invention: starch slurry is separated with granulated slag totally; Select the pond that clean, with wide cut Polypropylence Sheet place mat, then 90 ~ 120 object piano-wire screens are placed in pond, in sieve, spread gauze, mashing is contained on gauze, injected clear water, fully stirs, make starch bleed in pond with water, repeatedly add water, until starch is separated totally with granulated slag.
As the further scheme of the present invention: step (5) screenings is separated: the Radix Puerariae powder after pulverizing is put into centrifuge separation, and centrifuge speed is 1000 turns per minute, within centrifugal 10 minutes, namely obtains wet starch.
Compared with prior art, the invention has the beneficial effects as follows:
1. the invention provides a kind of Radix Puerariae fine powder preparation method, overall process is without any chemical addition agent, ensure product safety, health, pollution-free, molecular structure is not damaged, fully save the natural component of Radix Puerariae and contained nutritional labeling, the Radix Puerariae fine powder original color and taste made, pure in mouth feel, real is a kind of popular pollution-free food;
2. present invention process step is few, and equipment is simple, processing ease, is applicable to suitability for industrialized production;
3. adopt airflow counter-collision dryer as drying equipment, dry tenacity is large, the thermal efficiency is high, and treating capacity is large; The dry time used is short, ensures starch not gelatinization, and 55 DEG C of normal temperature are dried, and ensure that original physical property, make the fluffy degree of the inherent quality outward appearance raising corresponding to whiteness of product; In dry run, material contacts few with external environment, is not vulnerable to pollute, ensure that end product quality.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
Embodiment 1
A kind of Radix Puerariae fine powder of the present invention preparation method, comprises the steps:
(1) raw material is excavated: excavate fresh, without rot, unabroken Radix Puerariae;
(2) clean: by hand or machinery fresh Radix Puerariae is cleaned up;
(3) sterilization: Radix Puerariae is cut into sheet, is placed in the immersion sterilization in 15 ~ 30 minutes of 600mg/kg salt solution, and the wild elegant jessamine heel piece cleaning after immersion drains;
