  • Идеальная гомогенизация с мельницей Grindomix GM 300

    Разнообразие продуктов питания с их зачастую очень разными свойства- ми представляет реальную проблему для лабораторий, изучающих пищу Перед тем как провести фактический анализ, образцы материалов - которые зача- стую могут сильно отличаться по твердости и влажности - должны быть смешаны и достаточно мелко порублены. Ножевые мельницы Grindomix от RETSCH - идеаль- ный инструмент для удовлетворяния всех требований, предъявляемых пробоподго- товке пищевых продуктов. Модель GM 200 хорошо зарекомендовала себя в обла- сти измельчения небольшого количества материала (до 700 мл.). Для больших объемов компания RETSCH предлагает новую мельницу GRONDOMIX GM 300 с объ- емом размольного стакана до 5000 мл.

  • Измельчение в размере XL: Большой объем пробы, большая производительность

    Режущие мельницы, отличающиеся универсальностью и эффективностью измельчения самых разных материалов, удовлетворяют любым требованиям области применения. Новая мельница SM 400 XL дополняет модельный ряд режущих мельниц RETSCH серии SM и позволяет измельчать материалы с большим входным размером кусков. Эта мельница имеет объем размольной камеры 7.45 л, а максимально допустимая крупность загружаемых кусков пробы составляет 170x220 мм, поэтому большие объемы пробы можно измельчать максимально быстро и эффективно. Предварительное измельчение пробы вручную, как правило, не требуется. В этом отчете представлены различные примеры применения SM 400 XL.

  • Air Jet Sieving of Bulk Materials

    Particle size analysis and particle size distribution are important criteria for the quality control of bulk materials. In a running production process, the results of a quality check must be available quickly to allow for immediate adjustment of the production parameters. Depending on the expected particle size and sample volume, different sieving methods and sieving machines are suitable for analysis. The method used for particle size analysis is primarily determined by the fineness of the material to be sieved. For dry sieving of samples with particle sizes below 40 microns, air jet sieving is the method of choice.

  • Genetically modified organisms (GMO) - detection in food and feed samples

    Genetic engineering opens up new possibilities in areas such as medical research, development of alternative fuels or global food supply. It is used to modify the characteristics of plants in order to increase the crop yield, improve defense against predators, pesticides or draught, but also increase concentrations of essential vitamins. However, with regards to food the use of genetic engineering is a fairly controversial issue.

  • Hemp - Sustainable raw material for an increasing number of industries

    Hemp is a versatile plant material that has gained increasing attention in recent years due to its numerous applications and industrial importance. Hemp is a variety of the cannabis sativa plant species and is known for its high levels of cannabidiol and low levels of tetrahydrocannabinol. Hemp has been used for centuries for a variety of purposes including fiber, food, and medicine. However, in the last three years, there has been a significant development in the use of hemp for industrial purposes such as building materials, biofuels, and textiles.

  • Mixer Mill MM 400: Upgrade of a True Multipurpose Mill

    With the Mixer Mill MM 400 RETSCH has developed a true multipurpose mill which covers a huge range of applications, including classic mixing and homogenization but also more complex tasks like cell disruption via bead beating or mechanochemical processes. The ease of use of mixer mills in general, combined with a wealth of accessories make the MM 400 the perfect choice for quick, safe and reproducible processing of small sample volumes.

  • Quick and reproducible grinding of feedstuff

    Grain, compound feeds or feed pellets occur in a variety of forms; compound feeds are usually inhomogeneous. Feedstuff is analyzed, for example, to determine the nutritional value, to detect hazardous substances or genetically modified ingredients. To ensure meaningful and reliable analysis results, representative and homogeneous samples are required. Therefore, sample preparation involves homogenization and size reduction of the material to a defined particle size. RETSCH laboratory mills are perfectly suited for this process.

  • Representative results require adequate sample preparation

    The following situation is typical for many production plants: After a routine quality check, the production process is stopped or an already produced batch is suspended, because the analysis results were not within the relevant critical values. But does the tested product really deviate from the specifications? It is often not the product itself which causes irregular analysis results but a lack of understanding of the steps which come before the analysis.

  • Reproducible Sample Homogenization of Cannabis and Related Products

    The concentrations of cannabinoids and terpenoids are the main points of interest in the quality control of cannabis and related products. To ensure reliable analytical results, the sample preparation process for cannabis needs to be adaptable to the considerable complexity of the various plant matrices.

  • Sample Division of Large Volumes

    Representative sampling of large sample volumes is an integral part of the physical and chemical analysis of bulk goods and has a decisive influence on the quality of the results. Extraction of a sample from the bulk is not always carried out in a way to ensure representativeness. This is a widespread flaw in the quality control process with a negative impact on the subsequent analysis results. RETSCH provides some convenient solutions which help to improve working conditions and thereby the quality of the sampling process.

  • Small-scale Production and Quality Control of Cannabis and Related Products

    In the rapidly expanding world of cannabis legalization and consumption, ensuring the highest standards of quality control is paramount for safeguarding public health and safety. As cannabis products become increasingly available to a growing global market, comprehensive quality control measures are indispensable to guarantee consistent potency, purity, and safety. In this article, we explore the role of laboratory mills in quality control and small scale production of cannabis and related products.

  • Sticky, tough, moist – cryogenic homogenization of food samples

    The homogenization of food samples is a crucial step prior to the actual analysis. Due to the various properties of food – dry, moist, sticky, tough, hard, soft, etc. – a versatile laboratory mill is required to ensure reproducible preparation of the analytical sample. RETSCH’s knife mill GRINDOMIX GM 200 is employed in laboratories all over the world for the homogenization of food samples as well as samples with a high water, oil, sugar or fat content. This mill covers a wide application range, from granular products like rape seed, rice, soybeans to fibrous or tough samples like meat, fish, candy, cheese or plants.
