A mode for grinding solid products with an improved cleaning system of the grinding chamber has been implemented. 5.Grinding headset with long service life The grinding set of the mill is specially designed to work in extreme conditions – high productivity and high mechanical load. Special inserts made of knife-hardened stainless high-strength steel with the effect of forging the grinding chamber and cup ensure long-term operation of the mill when grinding solid and granular products. The knife made of high-strength stainless knife steel guarantees their high wear resistance.

The principle of operation of the mills is based on the grinding of the product, rotating at high speed with a knife in combination with a cyclic rotation of the grinding unit. In order to achieve uniform grinding and homogenization of the sample, the grinding unit must be tilted during grinding. The angle of inclination is set automatically according to the selected mode. FEATURES: 1. Programmable grinding modes The laboratory mill has two grinding modes: "Sunflower" - used for grinding oilseeds. "Grain. Feed" is used for grinding grain, leguminous crops, feed and raw materials for their production. Depending on the crushed product, the operator selects the desired mode of the grinding process. The installation of the grinding mode options is carried out using a specially developed program via a PC. It is possible to install an additional grinding mode using a PC. 2.Easy operation with information display. 3. Crushing of samples with a high fat content (up to 55%). 4. Sample preparation without heating. The special design of the grinding chamber (grinding is carried out in the upper bowl made of aluminum) and the use of special knives ensure rapid grinding and minimize heating of the sample, which eliminates moisture loss. According to the test results of FSUE "UNIIM", mills are recommended for sample preparation during the analysis to determine humidity. They are part of the installation of the measuring air-thermal ASESH-8 (RU. p.31.005.A No. 56847). 5. COOLING SYSTEM without forced water cooling. For continuous comfortable operation with the cooling system, the mill is equipped with two grinding cups. 6. Grinding of various types of samples.

To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

The principle of operation of the electronic diaphanoscope YANTAR is to assess the vitreousness of the image obtained using a digital camera. The vitreous value is calculated using a software-implemented algorithm using special calibration equations. The analysis time is 1 minute. Automation of the vitreous assessment avoids the error associated with the subjective opinion of a specialist. The use of specially developed calibration standards based on optical filters for uniform adjustment of diaphanoscopes permits to coordinate the operation of two or more devices remotely. The interlaboratory error in determining the vitreousness on the devices included in the network does not exceed the standard. All the results of the determination of the vitreousness of wheat with the corresponding grain images are stored in the archive. If necessary, specialists can print the protocols of the current or any of the previous definitions. THE ALGORITHM OF OPERATION: 1. Pour the grains into the cassette and close the lid made of transparent glass. 2. Install the cassette in the diaphanoscope. 3. Launch the program. 4. Choose a product 5. Software processing of the digital image of grains in accordance with the selected product 6. Calculation of computer results. In 2023, a new national standard GOST R "Wheat. Determination of vitreousness by optical-computer method".

According to the requirements of the standards, the cooler is included in the list of equipment for determining humidity with pre-drying. Usually, grain samples after preliminary drying are cooled in the laboratory room to ambient temperature. However, with such cooling, the ambient temperature reaches only the surface layers of the samples, which affects the results of the analyses. The principle of operation of the cooler is based on blowing sample canopies in mesh buckets placed on a stand by a fan rotating at high speed. Advantages: Rapid cooling of samples. Stable moisture distribution. Allows you to significantly improve the accuracy of the results of determining humidity.

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.

The mill provides grinding of agricultural crops according to the current standards regulating methods of determining their quality. Principle of operation: grain is fed into the mill dispenser, where an air-grain mixture is formed, which enters the grinding chamber. The crushed product is separated from the air in the cyclone and collected in a special removable container. After the grain supply is stopped, the air flow ensures self-cleaning of the dispenser and the grinding chamber of the mill. application It is used in the preparation of samples to determine the quantity and quality of gluten, the "drop number" and other indicators of the quality of crops by infrared spectroscopy and other laboratory analysis methods, which require a high degree of grinding of samples. The CALIBRE differs from its predecessor, the BOREY laboratory mill, by a drastic reduction in overall and weight characteristics. An additional advantage of the CALIBRE mill is the reduction in the number of structural elements. So the absence of the door of the grinding unit makes it possible for quick access to carry out work on cleaning the grinding headset. technical specifications: Volume of the receiving funnel, ml 400 Permissible amount of ground product per hour, kg 3 The grinding time of the suspension is 50 gr., from 25-35 The maximum size of the crushed product, mm 12 The diameter of the sieve holes, mm 0.8; 1.0 The speed of rotation of the grinding hammers, rpm 16 500 Minimum mass of the milled product, g 10 The maximum mass of the milled product, g 300 Overall dimensions, mm 400 x 445 x 400 Weight, kg 26 Noise level, dB 70 Power supply Single-phase AC 220 V, 50 Hz Power, W 1050 The response time of the overload protection system, from 2 GENERAL CHARACTERISTICS: 1.
