    The fluid bed dryer TG 200 is used in quality control, sample preparation and R&D departments. It permits the gentle drying of organic, inorganic, chemical or pharmaceutical bulk materials without localized overheating. Suitable materials can be coarse, fine, crystalline, fibrous or leafy. The powerful fan of the fluid bed dryer ensures optimal air throughput so that the products to be dried are loosened up and thoroughly mixed resulting in short drying times. With the interval operation the fluidized bed is mixed even better. Temperature, drying time and air volume can be set digitally and adjusted continuously.

    Application Examples

    Cellulose, coal, coke, compost, leather, pharmaceutical materials, plastic granules, refuse derived fuels, saw dust, soils, splints, waste samples, … 

    Product Advantages

    • Gentle drying, dispersing and mixing also of temperature sensitive materials
    • Very short drying times (~ 5 – 20 min)
    • Powerful fan for optimal air throughput
    • Easy handling
    • Interval operation for better mixing of the fluidized bed
    • Wide range of accessories including various containers
    • Memory for up to 9 SOPs
    • Motor with no brushes allows for long service life

    Function Principle

    Drying in the Fluid Bed Dryer TG 200 makes use of the fluidized bed process, a technique similar to the one used in large industrial dryers. Ambient air is drawn in through a filter. A blower moves the air across the heating elements, and ultimately forces it through the perforated plate and into the detachable drying container. The solid particles are blown upward and dispersed and thus kept separate from one another. This helps to avoid a caking and sticking of the particles as it often occurs when other drying methods are used.

    The air stream of the fluid bed dryer extracts moisture from the particles and then exits through the filter bag in the cover. Using the quick-clamp cover with the filter fleece insert is advisable when dealing with products finer than 100 μm in diameter. The 1000 watt blower provides an air volume of 185 m3/h at idle speed; heater output is 2000 watts. The air volume, heating power and temperature are infinitely adjustable. Temperature control is effected using he display gauge.

  • The cyclone mill TWISTER is specially designed for the processing of foods and feeds for subsequent NIR analysis. The optimized form of rotor and grinding chamber generates an air jet which carries the ground sample through the integrated cyclone into the sample bottle. The air jet prevents the material from heating up, thus preserving the moisture content.

    The provided sieves guarantee an optimum particle size distribution so that it is not necessary to recalibrate the NIR spectrometer. The rotor speed can be adjusted in 3 steps allowing for perfect adaptation to the sample requirements. Cleaning the mill is quick and easy as the air jet effects a complete discharge of the material from the grinding chamber.

    This new cyclone mill in proven quality optimizes the reproducible sample preparation to NIR analysis thus allowing for meaningful and reliable analysis results.

    Application Examples

    Cereals, Corn, Feed Pellets, Forage, Pasta, Pharmaceutical Products, Soy, Rice, Tobacco, …

    Product Advantages

    • Ideal for grinding feeds, grains, forage and other similar products
    • 3 controlled speeds
    • Cyclone separator with 250 ml collecting bottle for quick extraction of sample
    • No cross contamination thanks to easy cleaning
    • Convenient operating panel
    • Robust industrial motor 900 W with long lifetime

    Function Principal

    In the cyclone mill TWISTER size reduction is effected by impact and friction between the rotor and the friction surface of the fixed grinding ring. The feed material passes through the hopper (with splash-back protection) onto the rotor which is rotating with high speed and is thus submitted to preliminary size reduction. The sample is then thrown outwards by centrifugal acceleration and is pulverized between rotor and grinding ring. The 2-step grinding ensures particularly gentle but fast processing. The feed material only  remains in the grinding chamber for a very short time. The integrated cyclone provides cooling of the sample and the grinding tools. This guarantees preservation of the sample properties to be determined. The ground material is separated in the cyclone and collected in a sample bottle.

    The ultrasonic bath range UR includes three sizes for cleaning test sieves and grinding tools quickly and easily. UR 1 is for test sieves up to 203 mm dia., UR 2 for test sieves up to 450 mm dia., and the UR 3 for the simultaneous cleaning of up to 5 test sieves 200/203 mm dia. The gentle yet thorough cleaning of test sieves in an ultrasonic bath increases their working lives as damage which could occur during manual cleaning is avoided.

    Product Advantages

    • Fast, gentle, and highly efficient cleaning
    • Universal and compact
    • Easy to use, saves time and cost
    • Intensive dispersion and degassing
    • Low maintenance
    • Long life

    Function Principle

    A high-frequency generator in the ultrasonic bath produces about 35000 oscillations per second, which are transferred into the cleaning solution and cause it to resonate. The energy density of the sound field is so high that a cavitation effect sets in. Innumerable extremely small vacuum bubbles develop in the ultrasonic bath and collapse in microseconds due to pressure and suction. The pulses triggered by this remove dirt particles even at the deepest, least accessible places or they result in homogenization, dispersion and degassing.

    Applications: cleaning, dispersion, degassing
    Feed material: sieves, glass and metal components, suspensions
    Batch size / feed quantity*: UR 1: 1 sieve 200 x 50 mm, 8″ x 2″ // UR 2: 1 sieve 450 x 100 mm // UR 3: 5 sieves 200 x 50 mm, 8″ x 2″

    The Ultra Centrifugal Mill ZM 200 is a high speed rotor mill with unmatched performance. It is used for the rapid size reduction of soft to medium-hard and fibrous materials.

    Because of the efficient size reduction technique the ZM 200 ensures the gentle preparation of analytical samples in a very short time. The comprehensive range of accessories including a large variety of ring sieves and rotors as well as collection systems makes the Ultra Centrifugal Mill a versatile instrument that can be easily adapted to varying applications. The optional Vibratory Feeder is load-controlled via an interface and ensures a uniform grind at maximum output rate. When using a cyclone, the sample material is additionally cooled by the air stream and more rapidly discharged from the grinding chamber via the cassette pan with outlet. This effect can be increased by connecting a vacuum cleaner.

    With thousands of installations, the ZM 200 has become a standard for food and feeds, for the chemical industry as well as for agricultural testing.

    • Motor compartment and electronics protected against dust and material penetration
    • Comfortable parameter setting via display and ergonomic 1-button operation
    • Wide range of accessories including various collection and feeding systems, rotors and sieves

    Function Principle

    In the Ultra Centrifugal Mill ZM 200 size reduction takes place by impact and shearing effects between the rotor and the fixed ring sieve. The feed material passes through the hopper (with splash-back protection) onto the rotor. Centrifugal acceleration throws it outward with great energy and it is precrushed on impact with the wedge-shaped rotor teeth moving at a high speed. It is then finely ground between the rotor and the ring sieve. This 2-step grinding ensures particularly gentle but fast processing. The feed material only remains in the grinding chamber for a very short time, which means that the characteristic features of the sample to be determined are not altered. The ground sample is collected in the collecting cassette surrounding the grinding chamber or in the downstream cyclone or paper filter bag.
