Automatic hammer mill use in the detection of food fatty acid content
Changes of food during storage, making it the value in use has also undergone a change in economic value will also change. Countries to develop a new "quality of grain and oil storage decision rule, which provides for monitoring indicators of the different food storage, in order to ensure the quality of the food storage, such as the quality of the corn, mainly to its taste, color and appearance of the structure, internal traits, taste, tasting test. Detection process for these projects, the first grinding of the sample grinding should pay attention to the selection method to minimize the lead to the deviation of the determination results, the grinding method can choose the automatic whirlwind mill due to the grinding method error operating in the grinding process to reduce the damage of protein and fat.
Such as during the determination of corn fatty acids, the first sample preparation, and this operation is with the whirlwind crush grinding or automatic hammer type cyclone mill, concrete: take mixed sample of about 80 ~ 100g automatic hammer type cyclone mill crushed, for Fineness of one-time up to more than 95 percent over CQ16 (equivalent to 40 mesh) screen, crush the sample well mixed (sieve, sieve under screening range of samples) into the grinding jar reserve.
We use automatic grinder machine process, still there are some points to note, specifically three: Note 1: Fineness of GB/T5507 test samples, the use of other types of shredders can reach the fineness, grinding samples can only use the automatic hammer type cyclone mill. Once crushed reach the fineness of the automatic hammer type cyclone mill can not be used. Note 2: The crushed samples, in accordance with the equipment specification requirements, reasonable damper size, and control the injection volume, to prevent and reduce the feeding tube retained samples in order to avoid a feeding tube blockage, reduce the heat of the grinding chamber, caused by the fatty acid samples changes, each crushed 10 samples shall discharge tube to remove the clean-up. Note 3: Preparation of a good sample should be completed as soon as possible determination For a long time storage, should be stored in the refrigerator, the whole process should not exceed 24h. The sample was crushed You can also use the whirlwind crush grinding operation, this instrument is a good helper for sample grinding.
