C33 Hygienic vacuum conveyors with USDA acceptance meets the toughest standards and ATEX certification
After 5 years design and development, PIAB has now launched a new generation of Vacuum Conveyors for the Food industry which fulfils the most rigorous of the hygiene standards, the USDA. A further design criteria was to reduce energy consumption whilst maintaining the present high level of product throughput. The C33 can trace its ancestry way back to the first vacuum conveyors in the 1970s when PIAB pioneered conveying in closed vacuum systems using multi stage ejectors.
Vacuum is generated in a multi-stage air driven ejector mounted directly on top of the polished stainless steel ( DIN 1.4436 / AISA 316L ) conveyor module. A new range of pumps specially configured to maximise flow rates at typical conveying pressures is one of the key contributors to the increased performance of the C33 range. These pumps have no moving parts and create maintenance & wear free vacuum without the unwanted side effects of heat production, vibration & oil leaks. The vacuum conveyor works by creating a vacuum in a stainless steel container which is attached to a feed pipe and feed nozzle or similar feed station. Once the required volume of product has been sucked into the conveyor, the pump is stopped and simultaneously the bottom valve is opened to facilitate discharge and an air shock reverse flushes the filter maintaining filter efficiency for future cycles. The standard vacuum filter system can filter down to a particle size of 0.3 µ ensuring that exhaust gasses are essentially dust free. After product discharge, the conveying process can be repeated. Fully pneumatic or PC / PLC control systems are available.
Intrinsically free from electrical and mechanical ignition sources due to the air driven pump and pneumatic control system, the C33 has been successfully tested to the EC directive 94/9/EC for use in Ex Zones. All components are electrically conductive to ensure that the build up of static charge is minimised.
Typical applications include feeding dosing, weighing and packaging machines in the food and pharmaceutical industries where throughputs from a couple of hundred kg up to over 10 tonnes per hour are usual over distances from 3 m to over 50 m.
In contrast to GMP which is a declaration of conformity and intent, the USDA ( United States Department of Agriculture ) has, in cooperation with the 3A Authority issued clearly defined specifications which must be met before a certificate is awarded. The USDA committee is composed of representatives from the user and the manufacturing sides of the industry as well as the US Department of Health and the Department of Agriculture. The USDA section for milk and dairy products specifies the most stringent requirements, and the process machinery which meets these requirements may be used without further consideration in all other areas. All materials used, need to be FDA compliant, and the design and the way in which such a system is installed as well its use are subject to USDA regulations regarding materials, design, compressed air quality, surface properties and cleaning methods.
The C33 range has been designed to allow easy disassembly without tools and is easy and quick to clean.
PIAB has maintained a data base of products transported since the introduction of the first vacuum conveyors many years ago. Thus even at the quotation stage we can draw on a fund of product relevant experience. Nevertheless there is always a flow of new products which we are happy to test in our laboratories prior to quotation.
