Milk analyzer: characteristics and description

The production and processing of milk is one of the spheres of agriculture. Its obligatory stage is to control and evaluate the quality of raw materials. For this purpose, a number of indicators are calculated, which is carried out with the help of special equipment - a milk analyzer.

Purpose of the device

The milk analyzer is a device for assessing the quality of dairy products. It allows you to quickly and accurately establish the following indicators: density, fat content, availability of additives and harmful substances, lactose, acidity level, sample temperature, etc.

The milk analyzer analyzes the product without the use of chemical reagents. This ensures hygiene and environmental friendliness of the evaluating product.

The milk quality analyzer is usually used on farms, at dairy reception centers and at food industry enterprises. Also this device is often used in research laboratories.

Functions of analyzers

Universal models of analyzers allow analyzing samples of all kinds of dairy products with the most accurate results. Special preparation of samples is not required. Products with a viscous consistency can be immediately placed in the device without prior dilution.

Automatic analyzers measure the freezing point, electrical conductivity and composition of milk.

The presence of calibration instruments allows you to simultaneously analyze the basic parameters of raw materials, semi-finished and finished dairy products.

Measured indicators

The milk analyzer calculates the following indicators:

1. In milk: titratable acidity and density, amount of protein, fat, lactose, dry matter, casein, urea, free fatty acids.
2. In concentrated milk: the proportion of dry skim milk residue, the percentage of fat and dry matter.
3. In cream, cottage cheese curds and in children's food: the concentration of fats, proteins, SOMO and dry substances.
4. In yoghurts and other dairy fermented products: the amount of SOMO, glucose, lactose, sucrose, fructose, lactic acid, protein, fats, dry substances.
5. In dairy desserts: total carbohydrates, protein, dry substances, fat, SOMO, lactose, glucose, fructose, sucrose.
6. In cheese: the concentration of salt, the amount of SOMO, proteins and fats.

To carry out the analysis of milk on the specified parameters it is possible by means of professional devices of a domestic production.

Apparatus "Clover-1"

This is an ultrasonic milk analyzer that determines the protein, fat and dry skim milk content. Also, this device allows you to determine the density and temperature of dairy products.

The milk analyzer "Klever-1" works by a method based on measurements of ultrasound in milk with a certain composition and temperature values.

The advantages of the device:

1. The ability to measure many indicators.
2. High performance.
3. Accurate results.
4. Ecological and safety.
5. Durability.
6. Ease of use.

The required sample volume for analysis is 20 cu. See For an hour of continuous operation, the device can analyze 22 samples.

Analyzer "Clover-2"

The milk analyzer Klever-2 has great possibilities. The device measures the proportion of protein, fat, milk powder, lactose, the amount of defatted residue and added water. The analyzer also sets the freezing point and the degree of milk homogenization.

Analyzer "Clover-2" works in 2 modes. When choosing the first mode, a rapid or rapid analysis of the main indicators of milk quality assessment is carried out. In the second mode, the device measures the full range of milk and whole cheese parameters with maximum accuracy.

The device "Clover-2" is an improved model. The device is equipped with a liquid crystal display with a control menu. The user can choose the appropriate mode for himself and set the necessary settings.

The device is powered by mains. For the application of the device in the field conditions, it is envisaged to use a power source through the car cigarette lighter.

The analyzer can work 12 hours in a row. The built-in memory stores 100 measurements.

The time for express analysis is 3.5 minutes. For its carrying out, a sample volume of 20 cc is required. See Measurement of indicators in the second mode lasts 5.5 minutes, and the volume of the analyzed mass should be 200 cubic meters. cm.

Dairy analyzer «Laktan 1-4 M»

Another technical device of Russian manufacture - "Laktan" - has good technical characteristics. The equipment is intended for analysis at processing plants, on state farms and collective farms, in dairy kitchens and at milk reception points.

"Lactan 1-4 M" is characterized by wide functionality and optimal cost. A special feature of the device is the ability to determine the protein. Measurement of protein by the traditional method lasts up to 6 hours. In this case, it becomes necessary to use additional materials.

Ultrasonic milk analyzer "Lactan 1-4" provides stable results, minimum cost of analyzes and safety procedures. The device is convenient and easy to use. The analyzer is able to work qualitatively for many years.

The device can be connected to a computer to store and process the measurements. A cable and software are included in the kit.

Mini-analyzer Laktan

To assess the quality of milk in small enterprises, a reduced model of the analyzer Laktan 1-4 M Mini was developed. This compact device determines the fat content of milk, the amount of water added, the density and the proportion of SOMO.

Mini milk analyzers "Laktan" are manufactured to meet the needs of private farms, working with a small amount of dairy products. Initially, they were designed only to measure the fat content of milk. However, the manufacturer of the device was able to add several functions, which are usually used to assess the quality of dairy products. Therefore, "Laktan 1-4 M Mini" for today is successfully used in different enterprises, completely replacing large devices.

The device is equipped with a plastic case with a portable handle, in which the device is placed and the necessary accessories for analysis.

How to use

Basically, the preparation of the device for use and carrying out the analysis take place according to the following scheme:

1. Place the milk analyzer in a convenient location in an upright position. It is important that the surface is flat and stable. It is ideal to use the analyzer on a table or pedestal.
2. Set the desired mode of operation. After selecting the mode, the device will start to warm up. Usually, the warm-up is performed automatically immediately after the device is connected to the network. After heating, the display shows the readiness of the analyzer to work.
3. Fill a special sample container with the required amount of milk and place it in the apparatus according to the instructions. The sample temperature must be within the recommended values.
4. When performing an analysis using a sucking pump, you should install a tube with a tube and select the appropriate mode. Then fill the measuring cup with milk and put in the sampling site. After the milk is sucked into the device, measurement will start.
5. Analysis of milk without a pump occurs with the use of a piston, under the influence of which the milk enters the measuring chamber.
6. After the analysis is complete, the measurement results are displayed on the display.
7. To keep the device working, keep it clean. After using the analyzer, the measuring chamber and tubes should be thoroughly rinsed, following the instructions.
