ST006 Drop value meter .This product is suitable for the determination of A-amylase activity in cereals, flours and other starch-containing products，It is an important measuring instrument for quality verification in grain storage, flour processing, food processing and other fields.
This instrument is in accordance with the Hagbery-Perten method to determine the activity index of a-amylase in grain and flour, and implements GB/T 10361-2008 "Grain Landing Numerical Determination Method" in line with the national standard. The principle of this method is to use the principle of a-amylase on the liquefaction and decomposition of gelatinized starch to determine the activity of enzymes, and the viscosity of the gelatinized liquid decreases significantly after liquefaction and decomposition, so the content of the enzyme can be reflected according to the change of viscosity. The small drop value and low viscosity indicate strong enzyme activity. In the process of raw grain purchase trade and procurement, the use of landing numerical instrument to detect grain crops, according to the size of the landing value for separate warehouses, according to the quality of the price, refuse to accept malt wheat, will bring you unexpected benefits.
Technical features:
1. The key switch of this instrument adopts membrane soft key switch, which has a long service life. Other units use the ship-type model, this switch is used more times, easy to button failure, need to be replaced.
2. The control part of the instrument adopts intelligent single-chip microcomputer control technology, and uses a prompt light to indicate the next operation, which is more convenient to use.
