Smart blast freezer receives higher hygiene ranking CU LTIVATION AND TECHNOLOGY Slats on both sides of the evaporators ensure that ice formation can be removed within 20 minutes. mounted a total of 39 centrifugal fans. The advantage of this is that these fans show a good, regular characteristic. This means that we can operate them via frequency regulators so that they can often operate at a much lower capacity, which again saves electricity’, Van Bodegom explains. Growing hygiene demands AFE sells the blast freezers as ready-made modules. We ‘only’ need to weld the parts together and connect the blast freezer at the factory. This has made, for example, that we could start almost immediately at Farm Frites. However, this does require a proper organisation of the mega transport to transport the fourteen freezer parts. As this special road transport is often difficult to organise, we use inland craft to deliver the enormous modules to the nearest port to curtail road transport as much as possible. The advantage of this way of constructing is that there are no visible bolts and nuts in the blast freezer. Moreover, the cleaners can reach every spot. As we have mounted specially-developed LED lights, the freezer can be inspected everywhere. From experience we know that if cleaning is easier, it’s also quicker’, Van Bodegom explains. ‘Most of our cleaning is already automatically done with our automatic Cleaning in Place (CIP) system’, Van der Hagen tells us. ‘All our evaporators are cleaned with the use of spray pipes. Moreover, we have had special space balls with nozzles installed in the blast freezer and under the conveyor belt. These balls, which are used to the clean the tunnel, can also be compared with those in a dishwasher. We then heat the entire space with the steam of around 78° Celsius so that the inside is pasteurised. This only works if the seams have been expertly welded; this cleaning system doesn’t work with sealed joints. An important detail here is our new massive lights which have fully vulcanised with resin. ‘This means that the lamps can’t contain air, so that condensation and the subsequent algae and bacteria growth can’t arise, Van der Hagen knows from experience. In a reaction, Farm Frites let it be known that this blast freezer is going to be the blue print for the future Farm Frites blast freezer, also because independent Audit firms of important chips buyers have awarded this blast freezer with the highest hygiene ranking ever. ● Jaap Delleman We use inland craft to deliver the enormous modules to the nearest port to curtail road transport as much as possible.
