Problems solved by technology

However, it still cannot meet the needs of rapid detection of milk components
[0005] 2. The combination of interference filters is rarely used in practice because of its small wavelength, low measurement accuracy and is not conducive to the expansion of measurement items, and the spectroscopic measurement time is also long.
[0006] 3. Grating spectrometry, due to the use of mechanical scanning, the spectroscopic measurement time is still long, so it is rarely used in practice
[0007] 4. Fourier transform spectroscopy is not often used in practice due to long measurement time and narrow spectral range, which requires huge equipment and is expensive.
And when there is a large frequency jump, since the output frequency of the voltage-controlled oscillator is basically proportional to the input voltage, t

Abstract

The fast detector for milk component consists of light source, crystal, detection amplifier, fiber, measuring head, signal amplifier, CPU and driver. The driver includes a phase-locking loop comprising phase-detecting low-pass filter, voltage controlled oscillator and N frequency divider; and an amplifying output circuit comprising preamplifier, power amplifier and RF output interface; as well asadder, D/A converter and microprocessor. It produces adjustable HF signal in milk component detection and is suitalbe for in-situ detection of milk component.

Description

technical field [0001] The invention belongs to the category of food processing testing instruments, in particular to a rapid testing instrument for milk components. Background technique [0002] In the process of milk acquisition and production management, the detection of milk components is of great significance. Correct and rapid detection of milk component content can not only provide timely mastery and guidance for product quality control, but also provide scientific reference for excellent breeding of animals. Therefore, a rapid and stable milk component detection instrument has broad application prospects. [0003] Because fat, protein, lactose, solids and other components in milk have absorption characteristics to light, people usually use near-infrared spectroscopy for measurement. There are many modern infrared spectroscopy detection instruments, but from the spectroscopic type of the instrument, they can be divided into 4 main type...
