Prevention of Initial Supercooling in Progressive Freeze-concentration.
A physical method is proposed that uses a cooling plate with many small holes to prevent initial supercooling in progressive freeze-concentration, and thus avoid serious contamination of the ice produced. The higher chance for ice nucleation of the water molecules in the holes due to the temperature gradient in the cooling plate resulted in the initial supercooling being completely prevented. A...
متن کاملEffect of Flowrate and Coolant Temperature on the Efficiency of Progressive Freeze Concentration on Simulated Wastewater
Freeze concentration freezes or crystallises the water molecules out as ice crystals and leaves behind a highly concentrated solution. In conventional suspension freeze concentration where ice crystals formed as a suspension in the mother liquor, separation of ice is difficult. The size of the ice crystals is still very limited which will require usage of scraped surface heat exchangers, which ...
متن کاملRegulation of Supercooling and Nucleation in a Freeze Intolerant Beetle (Tenebrio molitor)’
The mealworm beetle, Tenebrio m&or (Tenebrionidae, Coleoptera), is a freeze-susceptible species that does not survive cooling to below the supercooling point (i.e., tissue freezing) in any stage of development. Most insects of a given age and developmental stage exhibit a relatively narrow range of supercooling point (SCP) values. However, Tenebriu larvae reared at 24°C on dry wheat bran displa...
متن کاملSupercooling point plasticity during cold storage in the freeze-tolerant sugarbeet root maggot Tetanops myopaeformis
The sugarbeet root maggot Tetanops myopaeformis (Röder) overwinters as a freeze-tolerant third-instar larva. Although most larvae are considered to overwinter for only 1 year, some may exhibit prolonged diapause in the field. In the laboratory, they can live for over 5 years using a combination of diapause and post-diapause quiescence. In the present study, the cold survival strategies of these...
متن کاملPrevention of nanoparticle aggregation during freeze-drying.
Nanoparticle formulations have been widely used in the drug delivery field. The majority of published articles dealing with nanoparticle formulations have focused on the use of freshly prepared nanoparticles, but not many deal with scale-up production of nanoparticles and their long-term preservation by freeze-drying. To date, little information is available on an effective freeze-drying proces...
