2. Description and purpose of the aerodynamic container wood dryer.
Aerodynamic container wood dryers are powered solely by electricity, they do not
require an external heat source: water, air or steam. They do not have electric heaters or
heaters. The source of heat is the work of the turbine (fan). By compressing and expanding air
molecules, the turbine increases the temperature and ensures air circulation and removal of
excess moisture from the chamber. The air flow is up to 170 km/h (47 m/s), which ensures
uniform and fast drying of the wood in every point and prevents cracking and bluing. Moisture
removal is carried out through ventilation chimneys installed on the dryer door, made of
stainless steel and aluminium. The upper chimneys remove the excess steam, while the lower
draws air from the environment.
Dryer is a mobile machine, of container construction, with no permanent connection to
the ground. It does not require the construction of foundations, concrete footings, etc. Dryer
inside is made of fiberglass (laminate) and polyester resin. The elements inside: the apparent
ceiling, the casing of the turbine system, the protective shutter, ventilation chimneys and
trolleys are made of stainless steel AISI 304. The remaining elements: the track (rails +
runway), the turbine, the engine base are made of steel S235 and covered with an anticorrosive
layer. Outside the dryer is covered with elevation sheet. Insulation is made of polyurethane
foam and acoustic glass wool. The thermal insulation parameter is about 0.25 W/m
2
. The free-
standing, weather-resistant construction allows it to be placed anywhere and immediately put
into operation after unloading.
The dryer is fully ecological, it does not have and does not produce hazards to the
environment. The ecological aspect results also from the power source which is electricity.
Aerodynamic container wood dryers are intended for drying only wood:
-of any species,
-of any initial moisture content (freshly grated or seasoned),
-of any size, including not edged (not foxed),
-impregnated or coated with substances that do not lower the nominal flash point of the
raw wood,
-europallets, box pallets, wooden packaging (in order to obtain ISPM 15 certificate –
commonly knows as IPPC).

4. Transportation and unloading.
During transport, the dryer must be properly and sufficiently secured. The driver or the
transport company is responsible for the transport. A forklift or a crane with a sufficiently large
lifting capacity is used to unload the dryer. In both cases, you must consider the dryer's center
of gravity, which is not always located in the middle of its length. When unloading the dryer
with a forklift or a forklift, it is necessary to remember about using suitably long forks and
about the principles of health and safety. In the case of unloading with a crane, special
unloading straps must be used (strength at least twice the weight of the dryer, length at least 6
m), wooden scantlings between the dryer and the straps (with dimensions: width > 16 cm,
thickness: > 8 cm, length: 290 cm), 4 ropes at least 6 m long of suitable strength, spacers to
protect the roof from damage and, of course, safety and hygiene. In case of any doubts contact
the dryer manufacturer.

5. Workplace setting.
The place where the dryer works can be under a roof or in an open area because, as
mentioned above, the dryer is fully weatherproof. In winter you should pay attention to the
snow lying on the roof, which in excess can cause damage. It is worth considering placing the
dryer under a shed, which will provide convenient loading and unloading of lumber during
snow or rain and will also be useful for seasoning wood. It is not advisable to put a concrete
slab or asphalt or even paving stones under the dryer. Instead, it is better to place the dryer on
wooden sleepers, and these in turn are placed on a substrate made of stone - gravel or clay with
a granulation of 30-60 mm. Such a base absorbs vibrations much better, besides, wooden
sleepers will not soak up water. If there is no other possibility and the dryer must be placed on
asphalt, concrete slabs or paving stones, the wooden sleepers must be at least 20 x 20 cm. If the
substrate is made of stone, the wooden sleepers must be at least 14 x 14 cm. The length of the
sleepers in both cases depends on the width of the dryer, while the number of sleepers should be
odd and in accordance with the formula: number of sleepers = the length of the dryer + 1 pc.
The sleepers are best made of coniferous wood, impregnated with a protective agent. The dryer
must be perfectly levelled both in length and width.
Aerodynamic container dryers for wood can have special openings in the floor, located
near the turbine system and at the door. The purpose of these openings is to supply fresh air,
which the dryer sucks in during the air exchange with the surroundings, and to remove excess
water in case of the sprinkler malfunction or carelessness of the operator. These openings, if
any, cannot be plugged and must be taken into account when positioning the dryer in the work
area on wooden sleepers.
It is important to level the door frame so that the door can open and close freely. If it is
difficult to close and open the door, raise or lower one of the sides (the right or left as seen from
the bottom of the container at the door) slightly by adjusting the wooden support. In case of any
doubt, contact the dryer manufacturer.

6. Connecting electrical and water systems.
Connecting the dryer to the power grid (TN-S type) must be performed by a person with
appropriate rights. A five-core copper wire of appropriately selected cross-section should be
used for this. The cross-section depends on the installed power and on the length of the cable
and is specified by appropriate standards. Connecting (bridging) N conductors with PE
conductors and the lack of the earthing fulfilling requirements of suitable norms is
unacceptable. The wire feeding the drying room must be protected with an appropriately
selected overcurrent and differential current fuse.
Before starting the dryer, the protective installation of the motor and the dryer casing
must be checked. It is inadmissible to connect the distribution board and then to use it without a
correct protective installation (PE). After connecting it is necessary to check if the direction of
engine revolutions is correct. The direction of rotation is indicated by the black arrow sticked
on the motor cooling fan casing. When looking at the motor cooling fan - it is supposed to
rotate clockwise.
Inside the switchgear there is a thermal protection installed in the upper right corner.
Considering the principle of operation of this protection based on bimetal, each start-up of the
motor must be preceded by at least 10 minutes break after previous operation or start-up
attempt.
The person responsible for operating the dryer (operator) must be trained by the
manufacturer. Without proper training, the dryer cannot be put into operation. The operator has
exclusive rights to operate the dryer and his primary duty is to ensure the safety of people
assisting him in the works related to unloading and loading the wood. THE DRYER
OPERATOR MUST MAKE SURE THAT THERE IS NO PERSON INSIDE BEFORE EACH
START-UP!
The dryer is equipped with a sprinkler for humidifying the wood, installed on the back
wall to the right of the electric motor. Connecting the water can be done in two ways. The first
one consists in placing a container with a capacity of several dozen liters, a few dozen
centimeters above the valve of the sprinkler. The second way is to connect the water directly
from the water mains with the pressure not exceeding 0,3 MPa. The sprinkler valve can be
opened only when the engine is running, otherwise it will be difficult to achieve the intended
purpose - increasing the humidity in the chamber.
7. Loading the chamber with wood.
For loading wood in the dryer can serve carts and elements on which the carts move:
rails - installed permanently inside the chamber, and the inrun (one or two-part) - an element
temporarily installed in front of the dryer. This equipment is optional, it is not an integral part of
the dryer. The wood is being stacked (placed) on the trolleys that are located in the driveway.
For the trolleys rolling it is allowed to use the forklift only. BEFORE DRIVING A FORKLIFT
INTO THE DRYER IT IS NECESSARY TO MAKE SURE THAT THERE IS NO PERSON
INSIDE! After the trolleys with timber have been rolled into the chamber, part or all of the
ramp shall be moved away so that the door can be closed. The trolleys in the dryer must be
properly and securely restrained before the drying process begins. BEFORE CLOSING THE
DOOR, MAKE SURE THAT THERE IS NO PERSON INSIDE THE DRYER!

Before stacking timber on timber trolleys it is necessary to check that the wheels on the
trolleys run freely and without resistance and to remove loose timber (bark, sawdust, shavings,
knots, etc.) from the rails and the inrun. When placing timber on the carts, the carts must be
secured against rolling.
Before driving carts inside or before loading the chamber without using carts, check
that:
-the protective shutter of the turbine system is not "clogged" with loose lumber: bark,
sawdust, shavings, knots, etc., and that the shutter is undamaged,
-the rails inside the dryer are properly and well fixed to the floor,
Sawn timber or elements subject to thermal processing, such as: Euro-pallets, box
pallets, wooden packages, can also be placed in the dryer which is not equipped with a set:
trolleys, rails and an overrun. The loading then takes place manually or with the use of a
suitably small forklift truck or a hand pallet truck. IT IS OBLIGATORY TO OBSERVE THE
PRINCIPLES OF SAFETY AND HYGIENE DURING THIS PROCESS. BEFORE CLOSING
THE DOOR AND STARTING THE DRYER, MAKE SURE THAT THERE ARE NO
PEOPLE INSIDE!
The distance of the stacked wood from the protective louvre of the turbine system must
be at least 25 cm. On the other hand, from the dryer door the wood should be stacked evenly
with the end of the apparent ceiling. The distance of the apparent ceiling from the door is,
depending on the dryer, approx: 11, 16 or 20 cm. The distance of the dried material from the
walls and the ceiling should be about 5 cm and ensure the loading and unloading of wood
without the possibility of damaging the chamber. In case of loading with the use of trolleys,
before stacking the sawn timber on the trolleys a few wooden squared timber of the size
ensuring the stability of the stack should be put.

The most important rules related to filling the chamber with material:
-A sufficiently large distance must be maintained between boards or elements made of
wood (pallets, wooden packaging). The ideal situation is when the door "sees" the back
wall where the turbine system is located. This ensures a free flow of air. If the dryer is
loaded too tightly, the turbine will not receive the right amount of air, which in turn will
cause limited temperature rise and insufficient air circulation between the materials,
-lumber or other wooden elements must form an even wall with equal distances between
them, both at the dryer door and at the turbine. This rule ensures that the pressure of the
air escaping from the apparent ceiling and that taken in by the turbine is equal. Not
adhering to this principle will cause uneven drying in the upper or side parts of the
stack, and in extreme cases bluish wood from which it is not possible to remove free
water,
-When filling the dryer with wood, remember that the height between the floor and the
apparent ceiling at the dryer door is 5-6 cm higher than the height in the turbine system.
The difference in height of the apparent ceiling is intended to stabilise the flowing air
and ensure uniform momentum across the entire width at the end of the space between
the apparent ceiling and the ceiling (at the door).
Spacers for stacking lumber must be made of sound wood, preferably hardwood, with a
solid section of 25 x 25 mm. The distance between the spacers for softwood is 80 cm and 60 cm
for hardwood. For thin boards, the spacers must be placed more densely. Make sure that the
spacers are placed exactly on top of each other vertically. Position the spacers perpendicular to
the length of the dryer or at an angle of about 45
o
to the so-called "Christmas tree". The second
way slightly improves the airflow. When the spacers are placed perpendicularly, the air flow is
only completely possible between the boards. The spacing between the boards should be bigger
the more curved (not foxed) they are and cannot be smaller than 10 cm. When drying edged
wood (with constant dimension along the entire length - equal) the spacing can be slightly
smaller. The distance between the boards is also affected by the thickness and width of the
boards. The ideal situation is if there is "visual" contact between the boards and the back wall of
the dryer. Not ensuring a free airflow from the door to the turbine decreases the dryer's
efficiency and increases the drying time. It is recommended that the first few times you put
smaller amounts of material, thus maintaining greater distances. Only after gaining experience,
you can fill the dryer with more lumber, reducing the distance between the individual boards -
until you reach the golden mean. It is better to load the dryer with a few less boards than to
choke the air flow. It is also recommended to choose coniferous lumber for the first few drying
cycles, which is a bit easier to dry, and of course cheaper. After each drying cycle, damaged
spacers should be removed, and good ones stored in a dry place. It is possible to dry wood laid
out perpendicularly to the length of the dryer. In such a case free air flow is provided by
spacers, which in traditional drying (parallel to the length) block the flow. Spacers in this type
of drying must be perfectly parallel to the length of the dryer. However, the gaps between the
boards, because of their perpendicular arrangement to the length of the dryer, can be small - a
few cm.

8. Service.
BEFORE STARTING THE DRYER WITH THE SWITCH LOCATED ON THE
CASING OF THE ELECTRICAL SWITCHBOARD IT IS NECESSARY TO MAKE SURE
THAT THERE IS NO PERSON IN THE CHAMBER!
Before starting the drying cycle, when starting the motor for the first time, it is essential
to check that:
-the turbine spins freely during acceleration without any unnecessary noise, friction, etc,
-The engine cooling fan is working properly,
-no smoke is escaping from inside of switchgear, there are no abnormal symptoms,
terminals of switchgear equipment are not loose, there are no signs of overheating or
burning, wires are not damaged and do not vibrate excessively, etc.
The dryer is started by means of the switch installed on the left side of the electric
switchgear (START/STOP), and by selecting an appropriate working mode of the analogue day
programmer. The START status means that the switch is in position "1", additionally marked as
"ON" in green colour. The day programmer can work continuously, or at a time set by the
operator. The shortest possible working or standstill time is 15 minutes. Setting the time of the
dryer's work with the use of the programmer enables using a cheaper electricity tariff or
adjusting the time of the dryer's work to the remaining energy-consuming devices in the
enterprise. It is necessary to remember that the dryer does not have long, several-hour breaks in
the work of the engine. The lack of air movement could cause the free water, which the wood
"gave up" and which is on the surface of the wood, to create conditions for the development of
moulds and fungi, and so in the long run cause blue stain.
Every time the dryer is stopped after previous work or an attempt to start it up, it is
necessary to wait 10 minutes before the next start-up. Dryer has been secured against reaching
the temperature higher than 70
o
C by the thermostat installed in the electrical switchgear. The
thermostat probe is located inside the chamber on the rear wall to the right of the turbine
system. It is possible to adjust the settings according to one's own preferences, as the thermostat
cannot set the temperature higher than 70
o
C.
The dryer also has two thermal protections associated with the motor. The first is
located in the upper right corner of the electrical switchgear and is a motor circuit breaker with
a bimetallic thermal protection device (characteristic designation: ABB MS132 or 165). It is not
permissible to adjust a setting which, according to the manufacturer, has been set to the value of
the motor rated current indicated on its rating plate. The purpose of this protection is to react as
quickly as possible to a voltage drop or failure in the power supply.
The second protection is the thermocontacts installed by the motor manufacturer on
each of the three coils. This protection is designed to stop the motor if the optimum operating
temperature of the motor is exceeded. When this protection is triggered the power to the soft
starter will be interrupted and therefore the motor will stop. The soft starter is a device for soft
motor starting and is installed in the switchgear on the right hand side, directly under the motor
circuit breaker. The soft starter has the characteristic designation ABB PSR25, 30, 37, 45, 60 or
72.
The electrical switchgear is also equipped with a residual current circuit breaker and a
6 A overcurrent fuse with short-circuit protection.
