Tetrapak Viscolab-Sterilab

Purpose

The Viscolab is a multi-purpose, thermal pilot plant, including a two-stage homogenizer, tubular heat exchangers (both monotube and multitube), scraped surface heat exchangers, a holding cell of variable length, a direct steam injection unit and a laminar flow cabin for aseptic filling. The installation is highly flexible allowing many different configurations and can be used for pasteurization, sterilization and UHT heat treatments at flow rates up to 300 l/h. Steam is supplied by a fire-tube steam generator producing 200 kg steam/h. An ice water generator provides cooling water of approx. 0C, representing a high cooling capacity. The installation is equipped with a cleaning-in-place (CIP) unit, including a plate heat exchanger and high velocity pump.

Maran Ultra 23MHz is provided with a 18mm variable temperature liquid probe and one-dimensional, unshielded gradients. The usage of a 10mm probe is possible. The connected PC is a Dell optiplex 210L.

Purpose

The MARAN Ultra is a pulsed field gradient NMR that can be used for a number of common application including measurements of solid fat content in edible oils and fats by the direct and indirect AOCS method and measurement of droplet size distributions of water-in-oil emulsions such as margarines en butter. However, those applications are extendable since the MARAN ultra is programmable.

TA Instruments AR2000 controlled-stress rheometer, air bearing, Peltier temperature control, normal force measurement, Mobius drive, Smart Swap system, starch cell

Purpose

This state-of-the-art rheometer is a highly versatile instrument, capable of operating in many control modes: flow, oscillation, creep, stress relaxation, as well as recent developed operation modes like parallel superposition and multi-wave testing. Being basically a controlled-stress rheometer, the super fast Mobius drive makes the AR2000 perfectly suitable for performing strain-controlled experiments. Due to the air bearing, the low inertia drag cup motor and rotational mapping, the instrument has a high sensitivity and is capable of detecting tiny differences in viscosity. The Peltier temperature control allows very fast heating and cooling rates in the temperature range from -10C up to 90C. Cone/plate, plate/plate and concentric cylinder measuring geometries are available. The starch cell is equipped with a specially designed rotor which prevents sedimentation of particles under gravity

Bohlin Instruments CVO50 controlled-stress rheometer, air bearing, water bath temperature control

Purpose

The Bohlin CVO 50 is capable of performing oscillation experiments to determine the viscoelastic properties of a material, flow experiments to determine the viscosity and flow behavior under shear, and creep experiments to examine material behavior under constant shear stress. Available measuring geometries include plate/plate (plain, serrated and sand-blasted), cone/plate and concentric cylinder systems.

TA Instruments, Advanced Tzero technology, modulated DSC, auto sampler, temperature range -80C to 400C, software controlled dual mass flow controllers, direct heat capacity measurement, automated opening and closure of cell

Purpose

Differential scanning calorimetry (DSC) is traditionally used to measure (as a function of time and / or temperature) heat flows associated with the transition of materials (crystallization, melting, glass transition, .). The Q1000 DSC is based on the advanced Tzero technology, which arises from a totally new DSC sensor design and heat flow measurement principle. This results in a highly improved baseline and better resolution. The Q1000 DSC is a modulated DSC (mDSC), which offers possibilities not available when using conventional DSC. A sinusoidal temperature variation (amplitude 0.01 to 10 C) can be added to the conventional linear temperature variation. Because of this, a separation of the total heat flow in the heat capacity associated (reversing) component and the kinetic (non-reversing) component of the total heat flow can be obtained. This allows easier interpretation of the processes taking place

GEA Powder Technology - Niro, rotary atomizer, electric heating system

Purpose

Spray drying is a drying technique in which solutions or pumpable dispersions are atomized into very small droplets which are captured by a hot air stream in the drying chamber. While passing through the drying chamber water is evaporated from the droplets, after which the drying air and powder particles are separated in a cyclone. The Niro P-6.3 spray dryer is equipped with a rotary atomizer, meaning that the fluid is atomized by a fast rotating wheel, the speed of which can be varied. The drying air can be heated up to 400C and the water evaporative capacity of the spray dryer is around 50-60 kg/h.

Leitz Diaplan light microscope is equipped with bright field, dark field, phase contrast and an incident light fluorescence illuminator, as well as a temperature control system (5-120C) and a Wild Photoautomat MPS and a Nikon Coolpix digital camera 4500 for images.

Purpose

Light microscopy is applied to study objects in the order of magnitude of 1 micrometer to 5 millimeter. In addition to structural details such as globules or fibers, specific staining procedures (Oil Red O, toluidine blue, Nile Red, etc.) make it possible to distinguish proteins from fats, starch, cellulose, mineral components, etc. Bright field images are the most common type of images that can be made with a conventional light microscope. Other techniques to highlight certain structures are phase contrast, dark field and fluorescence microscopy. At the research lab, the microscope is mostly used to investigate the influence of ingredients and processing conditions on food structure. By showing the distribution and physical state of specific food constituents, particularly starches and fats, the light microscope can give a visual explanation as to why foods of similar chemical constitution have markedly different textures.

Lloyd Instruments TA500 Texture Analyzer with load cells of 20N and 500N

Purpose

The TA500 is used to determine all kinds of texture parameters on a large variety of products, such as breaking strength, hardness, work for penetration, cutting force and adhesiveness. Depending on the forces applied during the test, the instrument can be equipped with a 20N or 500N load cell. A large amount of different probes are available for compression, penetration, breaking and cutting experiments, as well as a Kieffer cell for dough testing and grips for tensile tests.

Quaternary gradient, 0.1 - 10 ml/min <
Autosampler (200 samples) with variable injection volume and sample processing
Atlas Software
Evaporative Laser Light Scattering Detector with impactor mode

Purpose

The HPLC system is a highly automated and flexible HPLC system, which is (mainly) used for the analysis of mono-, di- and triglycerides, phospho- and sphingolipids and their derivatives. The ELLSD is a universal mass sensitive detector which enables the detection of all present analysts without any dependency of the structure of the molecule (unlike UV or IR detectors). Moreover, the detector is fully compatible with gradient eleution (unlike other detectors, like RI).
