Fat and crude fiber content two magic weapons
Feed is a general term for foods fed to animals. It includes feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, chowder, additives, whey powder, oil, bone meal, cereals, and sweet sorghum. The feed will generally contain certain nutrients, such as protein, fat, crude fiber and other substances. Moreover, the content of these substances is a criterion for distinguishing poor feed quality. Therefore, in the evaluation of feeds, we need to use some instruments for content determination, such as fat content meter and crude fiber content meter. The fat analyzer measured not only fat, but also organic acids, phospholipids, fat-soluble vitamins, chlorophyll and other substances, it also became a crude fat analyzer, the fiber analyzer not only measured cellulose, but also contains half Cellulose, cellulose, and lignin, and so on, so the fiber analyzer is sometimes called a coarse fiber analyzer.
Adipose analyzer: The result of the fat tester conforms to the national standard (GB5512-85). Therefore, it is recognized as an ideal device for fat measurement by the food, oil, feed, and other industries. The principle of the fat analyzer is the Soxhlet extraction method and the weight determination method to calculate the fat content. The instrument needs to dissolve the sample in an organic solvent, and then it is repeatedly extracted and recovered. Finally, the fat content is obtained by weighing. The fat analyzer can measure grain, feed, oil and various fat products with oil content in the range of 0.5%-60%. In addition, there are two ways to heat the fat analyzer: water bath and electric heating. Their principle is different, but it is more popular now and it is more practical to heat the water bath. This method of heating can control temperature and temperature rise, and heat evenly.
Fiber Tester: Fiber Tester is based on the current commonly used acid and alkali digestion method for the digestion of the sample, and then weighed with equal days to obtain the final content of crude fiber. The crude fiber analyzer mainly uses various substances to dissolve the protein, fat, etc. in the sample, and finally leave the crude fiber. Which need to use dilute sulfuric acid, sodium hydroxide, ethanol, ethyl ether and other chemicals, after appropriate treatment, to get the residue. Finally burned at high temperatures to calculate its content. The fiber tester can measure six samples at a time, greatly improving the test efficiency. Crude fiber gauges are now widely used in various food, feed, grain, food and other agricultural and sideline products in crude fiber content.
CNC machining/lathe machining turning is the workpiece is fixed on the lathe, using high speed rotating machine drives the workpiece, the turning. tool on the workpiece so the product shape is round. The maximum of our machines can clip the weight of 200Kg, maximum diameter of 450mm, length of 750mm. high speed 3000RPM. processing materials are commonly used in steel, copper, aluminum, stainless steel POM, PS, PMMA, and other metal and plastic.
