On the basis of the developed approaches and mathematical model (MM) of the bioactive products drying block is carried out the optimization problem of the equipment choice and its operation modes in view of deleted binary mixture an ethanol water composition changes. The analysis of the problem with engaging of the Pontryagin’s maximum principle has revealed optimal control structure. There is ...

Aim of this experimental work was to investigate the possibility of producing fruit powders without employing drying aid and to investigate the effect of drying temperatures on the final powder characteristics. Raw fruit materials (banana puree, strawberry puree and blueberry concentrate) were processed using three different drying techniques each operating at a different temperature conditions...

For this study 48 non-infected muscle, lymphatic and visceral bovine tissue samples were collected from an approved red meat abattoir and spiked with 8 x 10(7) cfu/ml of M. bovis. The different spiked samples were subjected to cooking and drying (drying through the process of biltong-making) processes in a controlled laboratory environment. Mycobacterial isolates confirmed as M. bovis by means ...

The effects of different drying methods (freeze drying, vacuum oven drying, and shade drying) on the phytochemical constituents associated with the antioxidant activities of Z. officinale var. rubrum Theilade were evaluated to determine the optimal drying process for these rhizomes. Total flavonoid content (TFC), total phenolic content (TPC), and polyphenol oxidase (PPO) activity were measured ...

In order to take advantage of heat released during composting, the autothermal drying process requires the maintenance of adequate air flow combined with temperature. The aim of this paper was to construct a drying tunnel enabling the automatic control and regulation of the basic process parameters for biomass drying (organic fraction of municipal solid waste together with plant structural mate...
