BUFFER WASHER FOR EMPTY CONTAINERS

Functioning

Machine designed for the washing and steam injection inside empty glass / PET / metal containers before filling.

The cycle consists in 3 phases:

1st phase: washing by sprinkling nozzles fed by a low pressure centrifugal pump protected by filters.

The pump is fed by the water contained in the hopper equipped with too-full device. The water comes from the Customer’s net. The pump is fitted with steam coil for water warming, thermostat for the water temperature regulation, thermometer, filter, electrovalve and condensate discharge device.

2nd phase: the inside of the containers is injected by a flow of steam controlled by a steam distribution manifold complete with electrovalve.

3rd phase: blowing of the containers in continuous by the air generated by a ring blower and a blowing manifold equipped with nozzles. The blower is fitted by a special air filter.

Manufacturing features

Basement in AISI 304 stainless steel plate with height adjustable feet supporting two opposed chains with rubber buffers driven inside sliding lanes in high-density polyethylene
Regulating system by geared motor managed by operator panel to vary the distance between the elastomeric buffers mounted on the chains, at the same time and simultaneously all along the machine, according to the containers’ dimensions (no need of additional equipment for format changeover to treat containers of different diameter and height)
Driving by geared motors controlled by inverter
No. 2 conveyor belts (one for containers feeding and one for evacuation)
Centralized lubrication
Electric control board in stainless steel
Safety protection system as per CE norms
Manufacturing in AISI 304 stainless steel, except for some parts which are in a different material suitable for their good functioning
The machine is adjustable to treat containers of different sizes.

On demand, the machine can be supplied with FEEDING TABLE FOR EMPTY CONTAINERS in AISI 304 stainless steel (diam. 1.000 mm) with round plane in plastic material (polyethylene).
