Fish Head Dryer
Self-Contained and 'Containerised'
The drying process takes place in a standard insulated 40 foot hi-cube ISO container. To permit handling (transport and lifting) through conventional cargo facilities (road, rail, ocean going), all the equipment is permanently installed within the container and no parts of it protrude outside the nominal ISO dimensions. For faster mobilisation, the plant can be fitted with a diesel or natural gas prime mover (RPE Unit), making it self-sufficient and independent of electric power supply. For technical details, please consult the following drawings (drag the pictures onto your desktop; they will open for printing in PictureViewer or Adobe Photoshop or any other graphic software):

Equipped for the drying of fish heads, the space allocated for the goods will accomodate 10X3X16 = 480 grids of 0,7X0,7 meter overall dimensions and 115 mm level-to-level heignt, providing a nominal area for the loading of 235 sqm. For thinner goods - such as sardine - grids with a lower level-to-level height can be applied, thus increasing the loading area. So could, for instance, 720 grids of 76 mm level-to-level heignt be accomodated, providing 353 sqm - 50% bigger - nominal loading area.
In Iceland, cooling can be achieved with ground water, which comes up at 4°C, and heating with geothermal. In other countries, refrigeration (heat pump) must be employed. The refrigerating equipment can be delivered to operate with any environment-friendly refrigerant, such as R717 (ammonia) or R404A (halocarbon), as preferred and/or specified by client. It is sized to dry 5.000 kg of the wet raw material within 80 hours, however, the drying time will vary with the size and shape of the product.
The refrigerating compressor is driven with a 44 kW electric motor and fitted with a speed regulator (frequency converter) for control of the capacity. The air handling unit consists of the propeller fan (green), the cooling coil (blue), the water (drop) eliminator (light-brown) and the re-heating coil (red), all joined together with sheet metal ducts (green). The fan rotor is directly driven with a 5,5 kW electric motor. An external condenser, for the rejection of the excess heat, has a fan driven with a 1,5 kW electric motor. The entire drying process is governed by a digital control (industrial computer) installed in the electric switch board (not shown in the pictures).
