Food Processing Exhaust

The Quickdraft Venturi exhauster is an excellent solution for a variety of exhaust processing applications in the food industry, including ovens, microwaves, fryers, blanchers, freezing tunnels, mixers and baking applications. Quickdraft Exhaust Systems are especially effective for high heat, grease and oil applications; offering dependable, consistent exhaust with far less costly maintenance downtime. We often add a Quickdraft demister vessel as the filtration device for the oven or fryer exhaust. The demister uses a three-stage process to remove grease and oil from the exhaust air. Proper exhaust flow often results in significant increases in production yield — an increase of up to 10 to 15 percent reported by customers with ovens that are retrofitted with Quickdraft exhaust systems.

Specifications

1Weather Enclosure

Encloses the motor and blower assembly to protect from the weather elements
Foot-mounted blowers
Solid floor with angle base, carbon steel construction with air inlet top
Access doors for electrical maintenance and manual damper adjustment
Acoustic lining available to reduce noise

2Pressure Blower

Remote from processing area
The blower will never come in contact with the exhaust stream, so it is more reliable and typically will not have to be cleaned
Reduced noise

3Venturi Exhauster

Superior design and precision manufacturing make the Quickdraft Venturi Exhauster the most efficient, consistent and reliable method for maintaining process exhaust requirements.

There are no obstructions to the exhaust flow and all moving parts are external to the air stream
Little or no maintenance
Consistent, dependable exhaust performance
Duct can be thoroughly cleaned without harming the blower
Designed for 24/7 operation
Long service life

4Exhaust Filtration & Odor Reduction

Carbon Filters

Removes odor from the discharge
Uses a mixture of activated carbon and potassium permanganate
Filter media is contained in several “trays” that slide into the housing
Trays are arranged in a chevron pattern to increase effective surface area
Access doors allow the media to be easily replaced

Demister Filter

A three-stage process is used to remove grease, oil and particulate from the exhaust air stream
– Knockdown and Velocity Reduction are used to slow the exhaust air stream and allow larger particles to fall out of the exhaust flow
– Water spray showers located at optimum locations are used to “scrub” the airflow of grease, oil and particulates
– A specially designed series of Demister filter pads capture as much of the remaining grease, oil and particulates as possible.
Filters are heat-resistant, woven-poly material several inches thick
Frames allow the cleaning crew to easily remove and reinstall for cleaning
Filters are made from various materials based on the maximum temperature of the exhaust

5Water Recirculation

Significantly reduces water consumption in the Demister Filtration System
Provides required flow for maximum filtration efficiency
Includes pressure regulator and gauge for flow adjustment
Automatically skims grease to separate drain
Automatically introduces make-up water to the sump
Stainless steel construction with a washdown duty motor

6Oven/Fryer/Microwave

Quickdraft works closely with many manufacturers who supply ovens, fryers, blanchers, washers, mixers, etc., for the food industry. Our systems are designed for the manufacturer’s recommended exhaust flow and exhaust temperature for your process.
