Pastries made from wheat flour, sugar, oils, and eggs are high in calorie content. Pastries are rich in nutrients and can provide various nutrients needed by the body, such as carbohydrates, proteins, fats, and vitamins. Minerals, etc., are easily absorbed by the body. Therefore, testing and analyzing the content of various nutrients mentioned above is of great significance for controlling the production of cakes and supervising the quality of cakes. The fat analyzer can effectively measure the fat content in cakes, because the test of fat, which is one of the main components of cakes, is an important indicator for evaluating the nutritional value of cakes. The fat in cakes is mainly derived from plant and animal oils added during processing, such as soybean oil, peanut oil, sesame oil, corn germ oil, palm oil, rapeseed oil, lard, and butter. These oils and fats are widely used in the food processing industry and have become an indispensable important raw material and supplementary material for grain, oil and food.
Through the fat analyzer control experiment, it can be seen that if the cake contains a certain amount of water, it has a certain effect on the measured value of fat. Non-dried cakes measured higher fat content than dried cakes. Due to the difference in moisture content of the sample, the measured sample difference is also different, the absolute error is 0.24% to 2.13%, and the relative error minimum value is 4.61%, the highest value is 19.7%, which will inevitably lead to product evaluation or product quality. Misjudgment. Due to the fact that inspection work procedures are often unreasonable in the inspection work, and the standard does not explicitly require the operator to carry out sample processing, so that the sample enters the inspection room, which is often the side to test the moisture, and the sample is directly measured to determine the fat content. The neglect of the drying of the sample, resulting in inaccurate test values. Because of the different moisture content of the sample, the difference in the measured results is very significant. The reasons are many, mainly due to the decrease in the adsorptive power of various substances and various molecules in the cakes, especially fatty substances such as Triglycerides, free fatty acids, etc., as well as a variety of waxes, phospholipids, various colors, essential oils, sulfides, aldehydes and ketones and many other impurities, when extracted with ether or petroleum ether, are all in organic solvents. It was extracted together, so it was extracted that "crude fat" caused a high fat measurement value.
Therefore, the analysis results of the fat analyzer showed that the amount of water contained in the sample directly affects the measurement of fat content. In view of the current inconsistency and rationality of inspection work procedures in the inspection work, the sample analysts are not standardized and inconsistent in the weighing of samples and operations, which results in a large difference in test results. Therefore, the determination of pastry fat is best performed using a sample after moisture measurement, or the sample is dried in an oven at 100±5°C for 2 hours, so that the measured value can be more accurate and reliable.

Heat Meters are one kind of meters measuring the heat
consumption. In order to save the energy and decrease the environment
pollution, the heat meters are more and more popular for the modern buildings.
Heat meters can realize centralized heating supply. Now with the rapid
technology development, the heat meters also experience a fast way of growing
up. Now the government of the world starts to pay much attention to the
building remolding and new buildings heat meter installation. As the new type
of energy calculation, the heat meters have the advantages of higher accuracy,
energy saving and easy installation.
From the functions of the different types of heat meters, there are mechanical
heat meters, Digital Heat Meter,Ultrasonic Heat Meters, M-bus Heat Meters and also wireless heat
meters. Our company, Berggruen Technology Co.,Ltd never stops the steps for
further higher technology research and development. We are devoted to study the
new technology in the world to make better quality heat meters.
