Performance simulation of a Heat Pump Drying System using R744 as refrigerant Organic Eprints
Bantle, Michael; Kvalsvik, Karoline H.; Tolstorebrov, Ignat.
Convective drying requires significant amount of thermal energy in order to evaporate water from the product. In most cases this energy, present as latent heat in removed drying air, is not recovered. However, the simultaneous availability of waste heat and thermal energy demand is ideal for heat pump applications. This case study evaluates the performance of CO2 as refrigerant in heat pump assisted drying system for grain drying. The system was designed for a thermal capacity of up to 400 kW. This allows a mobile design in order to move the heat pump system to different drying locations. The energy demand of the drying system is decreased to 200 kWh per ton of evaporated water, which equals an energy saving potential of over 70%. Estimated investment...

Superchilling of organic food. Part 1: Concept, State-of-the-art and Potential for small scale implementation Organic Eprints
Bantle, Michael; Claussen, Infrid Camilla; Tolstorebrov, Ignat.
The present report is a part of the ERA-NET project SusOrganic: Development of quality standards and optimised processing methods for organic produce. The superchilling concept and the state-of-art of the technology are summarized with focus on potential implementation for small scale organic production. Production of processed organic food is mostly carried out by small and medium enterprises in demanding, competitive market conditions due to competition from highly cost-efficient large scale producers of conventional products and producers of locally grown food without certification requirements. The superchilling concept can be applied for organic meat and fish products, hereby helping the producer to supply the market with high-quality organic...

Low Temperature Drying and Thermo-Physical Properties of Brown Seaweeds (Saccharina Latissima) Organic Eprints
Tolstorebrov, Ignat; Eikevik, Trygve Magne; Bantle, Michael.
The drying kinetics of brown seaweed Sacharina Latissima with and without blanching were investigated in temperature range between 10.0 and 38.0 °C. The drying process is more rapid for raw seaweeds. The effective moisture diffusivity coefficient (with respect to shrinkage) was found in the range between 0.5 and 5.0 10-10 m-2/s. Drying temperature influence on lightness and hue color parameter of the seaweeds. The salt content in raw seaweeds influence on the shape of the sorption isotherm at high relative humidifies. The differential scanning calorimetry of raw seaweed samples revealed glass transition at ultra-low temperature range, while it was not found for blanched seaweeds. State diagram for drying and freezing of raw seaweeds was made.

Processing and Quality Guidelines for Organic Food Processing Organic Eprints
Sturm, Barbara; Esper, Albert; Gebresenbet, Girma; Bosona, Techane; Bantle, Michael; Claussen, Ingrid C.; Tolstorebrov, Ignat; von Gersdorff, Gardis; Shrestha, Luna; Md. Saleh, R.; Pittia, Paola; Neri, L.; Santarelli, V.; Faieta, M.; Rocchi, R.; Massantini, R.; Moscetti, R.; Ferri, Serena; Raponi, Flavio; Bedini, Giacomo.
ForewordThese guidelines on quality and processing of organic foods have been prepared as part of the Core Organic Plus funded project “SusOrganic - Development of quality standards and optimi-sed processing methods for organic produce”. They intend to support actors in the organic food processing sector to simultaneously increase resource efficiency and product quality of their produce by providing deeper insights in raw material, process and product relevant aspects. The main focus of the presented work lies on the preservation of fruits, herbs, vegetables, fish and meat by the means of drying and chilling/freezing. THE AIMS OF THESE GUIDELINES ARE TO PROVIDE THE PROCESSORS WITH: • Drying related aspects • A deeper understanding for naturally...

Superchilling of organic food. Part 2: Storage test with superchilled organic salmon and pork chops Organic Eprints
Claussen, Ingrid Camilla; Gullsvåg, Per Egil; Bantle, Michael; Tolstorebrov, Ignat; Kvalsvik, Karoline H..
Superchilling of organic salmon and pork chop was investigated and the potential of the concept was documented for the organic sector, especially SMEs.Relative shelf life extension of 14 days compared to chilled product, were documented for both products. The colour of the product showed no significant changes between the superchilling and conventional chilling processes. However, the superchilled products shod an increased drip loss and reduced water holding capacity, whic was caused by the partial freeze damage. The shelf life of the superchilled product will depend mainly on sanitation, processing and cold chain conditions and not on the organic origin of the product. The performed investigations demonstrated the potential of the superchilling concept...

Effect of low and ultra-low temperature applications during freezing and frozen storage on quality parameters for fish Organic Eprints
Tolstorebrov, Ignat; Eikevik, Trygve Magne; Bantle, Michael.
The article reviews recent investigations in the application of ultra-low temperatures for high-quality long-term storage of fish. Changes in fish quality were discussed with respect to thermal events, which occur at low and ultra-low temperatures. Excellent stability of proteins was found at temperatures below the end of freezing point, when the unfrozen water content is at its minimum. Lipid oxidation was inhibited by preventing oxygen penetration to fish tissues rather than decreasing storage temperature. Thus, a significant part of fish oils remains unfrozen until temperatures of −110.0°C. The recommended storage temperature for high-quality long-term storage of fish is −35.0°C. Further decreasing storage temperature is unnecessary for industrial needs.
