Press the Start button OP ON N O As the grain dries the temperature of the outlet air rises and as soon as the temperature set in the outlet tem perature thermostat is reached the burner stops and the cooling phase commences The cooling phase ends as soon as the time set in the cooling timer has run out When the cooling phase ends the blower and the feeder stop immediately and the elevator stops after a delay 4 3Emptying Turn the selector switch in the control centre to position E and start the elevator by turning the elevator switch and the bottom screw switch to position 1 The dryer is emptied by increasing the speed of the feeder by means of a freguency converter Finally clatter the dryer empty by swinging its emptying cams 5 Malfunctions The malfunctions are indicated by relevant signal lights Always try to find out the cause of the malfunction before resetting it or restarting the machinery See point 3 6 Signal lights Antti Teollisuus Oy 40 408111 04 2014 Vacboost M13 THERMAL INSULATION Insulating the sections has proved to be the most profitable method of saving energy According to drying experi ments the saving of energy or increase of efficiency ranges from 10 to 15 per cent depending on the external conditions A hard stone wool insulation 30 mm thick reduces the conduction of heat via the outer surfaces to a tenth 82 W m It pays to insulate even the top tanks and the sides of the base This pr

10. If the air is flowing too fast it may not be able to evaporate the amount of water entirely that it otherwise would be able to absorb If the air leaves the heater too dry i e too hot useful heat energy will also be wasted If you reduce the amount of air you may need to reduce the oil flow as well the 2 stage automation does this automatically This is a concrete way of saving energy Equilibrium moisture content The dryer the grain gets the slower the water evaporates from the grains As a result the relative humidity of the outlet air decreases as the drying proceeds How to reduce the amount of air The flow of suction air into the heater is throttled by means of a manual air shutter If you restrict the flow of suction air into the heater too much the temperature of the drying air will rise too high and the upper limit thermostat will stop the burner from time to time Do not let this happen as it would drastically reduce the efficiency of the drying process and strain the dryer heater clearly more than if the production of heat was constant For remedy increase the air flow or reduce the oil flow Antti Teollisuus Oy 46 408111 04 2014 Vacboost M13 Measuring the amounts of air The amounts of air can only be measured under test conditions Relatively the amount of air can however be measured by measuring the pressure of air inside the dryer s inlet air channel The pressure of air is indicated by the height difference o
