Superchilling of organic salmon fillets and pork chop was investigated and the potential of the concept was documented for the organic sector, especially SMEs. Relative shelf life extensions of 14 days were documented for both products. The colour of the product showed no significant changes between...

The optimization of the refrigeration process was based on existing systems for chilling of Atlantic Salmon in refrigerated sea water (RSW). Two methods (continuous and interrupted) chilling of salmon in RSW were investigated. Significant increasing of brine flow for fish chilling from 150 to 600 L...

A process simulation of industrial heat pump drying of clipfish is performed and the energy consumption for different systems is compared. The components of the heat pump (evaporator, compressor, 2 condensers, expansion valve and controller) were dimensioned for a 250 kW (thermal) system and a...

Intermediate storage and mechanical stress treatment (bending) during clipfish drying is investigated for this industrial case study. A drying time reduction of 17.5% or 1.5 days can be achieved when the product is stored prior to the drying process in a climate chamber. A similar drying time...

Konseptet sluttørking i eget lager utnytter overskuddsvarmen fra varmepumpen i tunnelen til å varme opp uteluft til sluttørking slik at fisken kan tas ut av tunnelen før den er helt tørr for å frigi kapasitet og utnytte tørkeluften. Konsekvenser av ulike driftsforhold ble sammenlignet med et...

Studier gjennomført på tørking av klippfisk de seneste årene har vist at tørkehastigheten i siste del av tørkeperioden er liten, og at luftmengder og relativ fuktighet i tørkeluften i denne perioden i liten grad påvirker tørkehastigheten. Dette åpnet for å se på muligheten til å ta ut fisken fra...
