Vacuum conveyor has 9,000kg/hr capacities

Simmatic Automation Specialists has expanded its range of vacuum conveying systems by the addition of the Vtec hopper loader range.

The Vtec system comes in seven different sizes and in either vacuum or electric controlled versions.

With capacities up to 9,000kg/hr and distances up to 30m the Vtec is suited to the filling of packing machines, tablet presses, blenders, metering screw feeders and any other similar process systems. It can handle powders, granules, tablets and any other sticky free or non-free flowing material.

The multi-stage vacuum pump is powered by compressed air and generates vacuums up to -92kpa.

The Vtec is ideally suited to hazardous dust areas where traditional electrical equipment is expensive and untidy. The inbuilt vacuum control system allows for a free standing unit which requires a single compressed air supply only. Conveying, discharge, and dwell times are easily setup by the operator using the three dial knobs in the control cabinet mounted on the side of the hopper. The cycle timing is adjusted during initial setup matching the product conveyed and the system throughput rate.

The Vtec system can convey product from drums, 20-25kg bags, bulk bags or bag dump hoppers by utilising either a pickup wand or hopper charging adaptor. The conveying air flow can be manually adjusted to allow either lean or dense phase conveying. This minimises product degradation and line wear while maximising system throughput. The conveying cycle is a cyclic process filling the hopper then discharging at preset intervals.

The tangential inlet transition causes a cyclonic effect on the incoming product separating the product and conveyed air. The air then passes through the filter, multistage vacuum pump and out to atmosphere. The hopper exhaust valve opens discharging product into the down stream process below. The system continues until a signal is received closing the supply vacuum air solenoid valve from 10-36kg making them extremely light and transportable. Each unit can be easily dismantled into smaller more manageable sections allowing ease of relocation and cleaning by a single operator.

The side mounted quick release clips provide extremely fast access and reassembly to all sections of the Vtec hopper loader. Silicon seals ensure hygienic sealing between each section.
