Liquid spectrophotometer is an instrument specially used for liquid color measurement. It adopts the D / 0 structure specially used for measuring transparent liquid. Liquid spectrophotometer can help enterprises control the color consistency of solution. Liquid spectrophotometer is simple to operate and fast to measure. Take a look at the application of liquid spectrophotometer in tea and beverage.

With the continuous development of tea culture industry, the degree of tea beverage being respected by the public in the tea industry is also increasing. The color of tea beverage represents the quality of tea beverage to a great extent. CHNSpec technology transmission liquid spectrophotometer has been applied in the color detection of tea beverage.

In the processing of tea beverage (as shown in Figure 1), pH value and heat treatment have a great impact on the color difference of tea beverage. The difference and difference of processing process result in a certain color difference of finished tea beverage. This requires to distinguish the color difference of different finished tea drinks to ensure the quality of tea drinks.

Around the theme of tea culture, a technology company in Shenzhen is constantly innovating and changing, and is committed to the all-round exploration of tea culture industry. Relying on tea culture and combined with finance, the company has achieved rapid development. The leaders of the group company attach great importance to the field of high-tech biotechnology. The increase of business models will also provide more opportunities and space for the development of the group company in the future. The company has very high requirements for products. As one of the main products, tea drinks need to pass strict production processes and quality inspection. With the improvement of the company's quality requirements, the previous method of identifying color difference with low-precision instruments can not meet the requirements. Therefore, the method of identifying color difference with the transmission liquid spectrophotometer of Hangzhou CHNSpec technology is sought, So as to improve the quality requirements of products.

The transmission liquid spectrophotometer CS-810 of Hangzhou CHNSpec technology (as shown in Figure 2) adopts internationally accepted D / 8 (integrating sphere diffuse illumination, 8 ° observation angle) SCI / SCE compatible lighting observation conditions and etc real-time calibration technology, in which the instrument will calibrate the system hardware and software during each measurement. This technology fundamentally solves the problems of long-term measurement stability and data drift of color measurement instruments. CHNSpec technology has a number of national invention patents on this technology. It eliminates the subjectivity of visual colorimetry and provides greater sensitivity and repeatability. At the same time, the instrument can be used through the connection between PC and color management software, which is convenient for enterprise quality monitoring and color data management. It can digitize users' color management, compare color differences, generate test reports, provide a variety of color space measurement data, and customize customers' color management. Meet customers' high requirements for color quality.

The following describes how to actually measure the color difference of tea drinks through CS-810.

Step 1: install the instrument, connect the instrument to the computer, turn on the instrument, conduct black-and-white calibration, and prepare the standard sample and sample of tea beverage to be tested (as shown in Figure 3);

Figure 3 - standard sample and instrument after black-and-white calibration

Step 2: open the sample room, put the tea beverage standard sample in and start the test (as shown in Figure 4);

Figure 4 - standard sample test of tea beverage

Step 3: after the standard sample is tested, take the standard sample out of the sample room, put the sample in, and start the test (as shown in Figure 5). Be careful not to let other human factors affect the test results;

Step 4: after setting various parameters, the test data can be obtained (as shown in Figure 6);

Figure 6 - test results

The results of the actual test are very satisfactory to the customers. Through the test data, it can be seen intuitively that the liquid transmission spectrophotometer has perfectly solved the customers' requirements in the color difference detection of tea drinks. The company has decided to purchase a CS-810 of CHNSpec technology in the near future to improve the product quality, improve the production efficiency, reduce the defective rate of products and increase the production efficiency, It is also conducive to further improve the credibility of enterprises. I believe that in the future, the two sides can reach a broader mutually beneficial and win-win relationship and jointly create brilliance!

The products of Hangzhou CHNSpec Technology Co., Ltd. are widely used in domestic printing, coating, auto parts, metal, household appliances, gold standard test paper, food safety, medical inspection and other industries and scientific research institutions. At the same time, the application scope of the industry is still expanding. The company has unremittingly carried out technical research and development and improved brand services to ensure the stability of the company's products, And is committed to providing users with high-quality products and services.
