DUSTSTORM: SAFE DUST EXTRACTION IN THE FOOD INDUSTRY Dust explosions can be extremely violent and serious, destroying not only the dust collectors but also nearby plant and injuring or worse, personnel. When bagging, tipping and mixing powder ingredients in the food industry, dust must be captured effectively to avoid such a serious event. TP03731 NZDuct 70 Years NZEN Ad 107.5x290_2.indd 1 29/03/16 1:06 pm Danish filter, fan and duct manufacturer JKF make the widest range of filters worldwide and the DustStorm range of units are fitted with explosive release membranes to the European ATEX standard. A membrane in the side of the unit releases the force of the explosion, and a valve fitted into the duct, from production area to the filter, will clamp shut on detecting an explosive event, protecting those inside from further harm. Flour, so commonly used in food factories, especially those manufacturing baked goods, requires safe and efficient extraction systems, as the health risk from the inhalation of flour dust has been attributed to this group of workers suffering from asthma or similar conditions. Flour is also an established explosive risk in manufacturing. A well-known Dunedin bakery recently fitted a new dust extraction system into its bakery and chose a JKF DustStorm filter, DS-20, to deal with the issue. To target the areas where the initial problem arises, stainless movable arms supplied by NZ Duct+Flex were located at suitable points around the factory where bagging, tipping and mixing takes place. These actions can lead to flour dust plumes releasing dust into the work environment. Manufactured in Europe and fitted with food-grade flex at the hinged joint, the arms can be moved out of the way for convenience when not needed, then pulled back into position to best capture dust using the all-round grab handle. The arms are connected by a central duct that leads out of the factory to the Danish made fully automated dust collector also supplied by NZ Duct+Flex. The DustStorm DS-20 unit not only offers the safety features, it also has a number of energy saving features. DustStorm filter model DS-20 with ATEX approved explosion membrane Energy reduction is achieved as the DustStorm includes the JKF patented PowerPulse filter cleaning system. Unlike conventional compressed air pulsed dust collectors, (which simply pulse compressed air into the filter cartridges every 30 seconds or so), the DustStorm unit senses the dust build up automatically, only cleaning when it senses its required. In addition, the pulse uniquely adjusts the force of the pulse between 1.5 and 5 bar. All other competitor models are using one power - normally 5-6 bar. This saves up to over 90% of compressed air against conventionally timed systems. Having a gentler cleaning operation also helps filter sock or cartridge life; 10 years and more is common. The DustStorm range has six different models ranging in capacity from 3000m3 to 60,000m3 of air and dust, depending upon the process concerned. Other JKF filters available from NZ Duct+Flex are designed for fumes and dust from every conceivable food production type and thousands of these systems are operating worldwide. JKF dust collectors have over 70 years of manufacturing and usage experience built into them and, due to the production capacity of their Als plant, ( over 40 large filters a week can be shipped by the company), they are available at very completive pricing, often less than the older, less efficient, less safe designs.
