Our bottle washing machine LSM has a very clear structure. Thanks to its relatively small dimensions and its low space requirements, there are several ways to set it up. The machine is supplied fully assembled. It is not necessary to build foundations or install it in a pan. It is erected with clearance from the floor using tilting feet. The installation time is very short. A large number of types enables the performance to be adapted to each individual operational requirement. The individual type numbers give the number of bottle cells in a bottle basket. All common types of bottle can be processed, from 0.2 litres up to 1 litre DIN sizes, of whatever type.
Bottles enter and leave the unit on one side, above one another. For each operation, the best means of supplying bottles can be selected, from a direct single row supply, via the four-row, tilted magazine feed, up to a slat conveyor magazine feed, an accumulation table or a multi-level feed. When bottles are output, the bottle tops do not get caught in the bottle cells. An extractor hood and a cold water curtain enable the bottles to be output without a vapour cloud.
The soiled water produced when dregs are removed and the bottles are initially sprayed is fed directly to the waste water shaft. This reliably avoids re-infection, soiling of the machine and premature usage of the cleaning solution. In addition, a warm water jet controlled by a solenoid valve allows heat and water to be saved efficiently.
A cleaning solution immersion unit together with several vigorous waves rolling over the bottles ensures that the loosened labels are removed. A rotating drum sieve with a blower extracts the labels from the cleaning solution and ejects them into the collection basket. An inclined sieve and a pressure filter provide some more filtration.
An automatic pusher at the rear bottle guide prevents the bottle tops from falling forwards. Feed rods together with feed pawls guarantee the precise centring of the bottle baskets over the spray nozzles.
There are high pressure jets of a separate cleaning solution and subsequent warm water bath. Between the individual stations, generously dimensioned drip-off zones prevent solutions from being transferred. The spraying can be ideally monitored via large windows.
Eight temperature levels with a controlled temperature profile guarantee careful treatment of the bottle glass, resulting in a very low breakage rate.
An electric switchbox thermometer, pressure gauge and other important controls are mounted in such a way that they are always in the operator's field of view and working area.
