LIPPERT – The drying specialist
Leading technology and more than 50 years experience form
the basis of LIPPERT'S unique success in the drying field
in the ceramic industry.
The reference list spans more than 1000 drying installations
in more than 40 countries.
Whether porcelain, ceramic, refractory material or "new
working materials", - from large volume sanitary items,
dishes, flower pots, oven tiles, tiles, to the most sensitive
catalysors – LIPPERT has the know-how.
More than 200 employees contribute their own personal
expertise, dedication and in-depth branch-specific experience
Steady research and development
LIPPERT has been working successfully on improving drying technology
for decades. A variety of modern mobile test dryers are always
in use at market-leading firms in the ceramic industry.
LIPPERT has set the standards in controlling technology through
application-specific software with graphics and operational
data systems.
The results are extremely short drying times, an excellent
energy balance and the high flexibility of LIPPERT dryers.
Custom designed systems
LIPPERT creates individual drying systems. Every drying task
is analysed. All relevant factors such as products, performance,
production processes, space availability etc. are considered.
LIPPERT conceives in this manner the individually optimized
dryer.
Compact, versatile und fully integrable: the box-pallet compact
dryer with fully automated loading & unloading. Efficient use of space.
Suitable for a wide variety of products.
Integration in material flow
LIPPERT
sees the dryer not as an "isolated island", but
rather as an integrated element in an optimized production
process. For this reason, material flow plays an important
role in the conception of each dryer. This is true for the
transport of items within the dryer, automatic loading and
unloading, integration with pre- and post-warehousing as well
as for intermediate storage.
One of the approaches used by us to interlink in-house
production facilities (e.g. shaping, drying, glazing or firing)
involves the use of laser-controlled driverless transport
vehicles,
also known as automatic-guided vehicles. These vehicles are
equipped in a fashion which allows them to enter into dryer
chambers even while the chambers are still hot, for unloading
and subsequent reloading of the chambers.
LIPPERT delivers complete systems solutions – the only
way to ensure real efficiency.
Efficient air conduction
Air
conduction is responsible for sufficient quantities of air
with the proper consistency reaching the entire product surface
entirely. Products are, however, different.
For this reason, LIPPERT develops air conduction systems with
the product in mind using horizontal, vertical, combined
or directed nozzle drying. Uniform reversal of the air flow
in continuously adjustable time intervals and continuously
adjustable air quantities are a matter of course.
A word about the airing principle:
Drying air is continuously circulated and reheated by the
air-heater. Vents ensure that no more than the required amount
(determined by the accrued water quantity) of air and thereby
energy is removed from the system.
This results in:
- Uniform and thereby gentle and rapid drying at each point
- Greater effectiveness, as the entire air flow is always
directly aimed at the product
- No maintenance-intensive mechanical moving parts in air
processing
Flexible Drying to Meet the Highest Quality Standards
In
addition to the precise control of temperature and humidity
during the drying process, LIPPERT have added aerodynamics
as a third drying parameter. Whether you require a two-stage,
a multistage or an infinitely variable process – an
aerodynamic drying program permits significant reductions
in drying time, minimizes breakage rates, and decreases energy
costs. In principle, this method involves the adaptation not
only of the air temperature and relative humidity, but also
of the air velocity, to the specific requirements of the various
goods to be dried. For instance for sanitary products three
drying cycles per day can be achieved.
Optimized Temperature and Moisture Control
Climate-controlled
drying:
At the outset, the articles to be dried are heated through
uniformly and gently in a moisture-rich environment augmented
by a humidifier. This warm-up phase is followed by the actual
drying process at high temperatures.
The temperature course, ambient moisture course, and air speed
course are preset, monitored, regulated and recorded.
For chamber dryers, these presetting, monitoring, regulating and
recording tasks are performed by individualized,
product-specific drying programs which can be stored and
retrieved.
In continuous-flow dryers, the articles are moved through
individually regulated drying zones with individually preset
conditions.
This allows:
- Short drying times even for sensitive products
- High flexibility through wide range application and rapid
and easy alterations through program loading
Maximum Ease of Operation
Thanks to its integrated PC with user prompting and
application-specific software, the control system offers the
user the utmost in ease of operation. Entry, storage and
retrieval of the desired temperature, ambient moisture, and
air speed parameters is straightforward, easy to follow, and
swift. No programming skills are required.
Well-structured and easy-to-follow representation of the
measuring values on the colour monitor. It is possible to control several dryers with a single PC.
An integrated process data acquisition system permits the
polling of all
desired values and actual values at any time required, both as
current status
information or over certain periods of time, via screen or
printer.
The
integrated fault diagnostic system reports faults and records
them in a fault log. Even deviations from desired values are
reported. Restart after a power failure is possible right from
the drying program's precise instant of failure. This
minimizes down times and maximizes plant efficiency.
State of the art construction Energy saving systems
The most modern construction elements:
The dryer framework consists of stable steel supports, lacquered
or galvanized.
Self-supporting sandwich plates filled with PU-foam or mineral
fibres are used for walls and ceilings. They guarantee the
best insulation.
Doors are customized for each production process and space
availability, e.g. rolling doors, hinged doors, sectional
doors or sliding doors.
Energy saving heat recirculation systems:
LIPPERT takes advantage of any desired heating method including gas,
oil, warm water, steam, electricity, etc.
The advantages of all feasible heat recirculation systems
are exploited:
Direct heat recirculation through controlled feed of kiln
waste heat or the use of waste heat from hot drying zones
for the next cooler drying zone (for dryers with several drying
zones).
Or indirect heat recirculation through heat exchangers (air-air
or air-water heat exchangers).
Camera-base article-recognition and position-sensing system
Digital camera systems in combination with handling robots enable
safe and reliable handling of mixed-series articles.
Fast recognition of the type of article, together with precise
identification of its position, permits millimetric grasping and pinpoint
placement of the articles for further automated production, e.g.,
robotized spraying, loading and unloading of pallets, etc.
