IAPAN - Equipment

Laboratory of Physical Properties of Fruits and Vegetables

Testing strength of materials under static loads
Axial testing: compression, stretching, bending, creeping and stress relaxation
Determination of forces, deformation, energy and elastic modulus of examined materials
Operating speed: 0-1000 mm/min, force range 10 kN (precision 0.1%), operating space 1635 mm (precision 0.1%)

Examples of use:

Model research, strength assessment, analysis of flexibility, flowing and stress relaxation of plant, animal, dairy, construction and dental materials
Comparative assessment of mechanical properties of crops, determination of strength parameters of structural components used in agriculture and agricultural and food processing machines and equipment

Strength testing of materials under static and dynamic loads
Axial testing: compression, stretching, breaking, creeping, flowing, fatigue and cyclic
Force range 25 kN, operating range 50 mm, frequency up to 50 Hz

Examples of use:

Model and fatigue research, strength assessment, analysis of flexibility, flowing and creeping of any materials under static and dynamic loads
Comparative assessment of mechanical properties of apples, raspberries, and sprouts of flowers and rape

Records objects image at a resolution of 752 x 582 pixels and saves each pixel in as RGB components
Measures sizes and shapes of objects
The time domain screen enables capturing an image sequence at defined intervals and as on-line playback
Assessment of heterogeneous or variable colour of the objects which cannot be measured with conventional spectrometers. Allows recording the entire or selected areas FOV image of the sample
Sample size: 240 x 280 x 120 mm
Measurement time: 1-2 s
The contact-free system ensures that the consistency and texture of objects do not affect the measurement results

Examples of use:

Examination, analysis and assessment of colours of any material
Quality testing of various products, including fruits and vegetables. Quantitative assessment of colour and appearance – a quality control system which enables the user to decide if tested products meet the required criteria of colour and appearance

Instrumental measurement of colours in the visible range of reflected light using the L*a*b* colour system by CIE in laboratory or field tests
Measurement field diameter: 11 mm

Examples of use:

Examination of the impact of agricultural technology, harvest, transport, storage and shelf-live of fruits and vegetables on behavior of optical properties of product surface
Qualitative assessment and classification of fresh and processed fruits and vegetables
