What you always wanted to know about drying, but...


First day of the seminar - 10/05/2016


Opening of the seminar



brick and water

Plasticity of bricks by interfacial reactions, boundary and surface tension between water, minerals and air, measures for the efficient reduction of the mixing water content by mineral and chemical additives


Coffee break



Moisture transport and shrinkage in the drying brick blank

Water transport in the raw material, shrinkage gradients as a function of the moisture conductivity and the final shrinkage, reduction of shrinkage gradients by improving moisture conductivity


Power requirement of blank drying

Kinetics and energetics of the drying process, energetic differences between  chamber and through-flow dryers, influence of supply air temperature and supply air on power and energy requirement of drying processes


Individual lunch



Energetics of alternative methods

Complementation of convection drying by direct heat supply, steam injection, microwave heating, low energy drying


Strength development in blanks during drying

Dependence of the blank strength of temperatures and local water content; Dry break strength and influence on the drying energy requirement, crack sensitivity


Heat recovery from moist dryer exhaust

Recuperation of the dryer exhaust with partial condensation for the partial recovery of the heat of evaporation, possibilities for active heat recovery by heat pumps and similar processes

ca. 18.00 

comfy get-together in the IZF                                                        


Second day of the seminar - 10/06/2016



Practical dryer design

Compensation of temperatures and humidities as well as design of the drying curve, effects of changing drying performance, dry measurement and measurement methodology


Determination of savings potentials for raw materials and raw materials power consumption

Financing and implementation of resource efficiency measures, guest lecturer Dipl.-Ing. +A. Kunsleben, efficiency agency NRW


consulting activities

Use of results from energy and environmental management


Coffee break



Composite heat storage unit for dryer flexibility

The drying energy demand fluctuates with day and week time, with product type and weather. To reduce the additional heating, heat accumulators are suitable, which are charged with excess heat and discharged at high drying energy requirements.


Drying Problems - What to Do?

Cause of origin, capillary transport of water-soluble salts, dependence on the drying conditions, avoidance strategies


Final lunch together


ca. 14.00
