An experiment was conducted to standardize the post harvest technology for Tinospora during the year 2006-07 at Medicinal Plants Unit, Horticultural College and Research Institute, TNAU, Coimbatore. The stems of 18 months old climbers were harvested and cut into pieces of different sizes (2.5, 5.0 and 7.5 cm) and subjected to sun drying in temperature ranging from 29 to 34°C during day time and...

in this work, a hybrid gmdh–neural network model was developed in order to predict the moisture content of papaya slices during hot air drying in a cabinet dryer. for this purpose, parameters including drying time, slices thickness and drying temperature were considered as the inputs and the amount of moisture ratio (mr) was estimated as the output. exactly 50% of the data points were used for ...

The objective of this study was to investigate the effect ultrasound pre-treatment (50% US and 100% US-soaking), temperature (80, 90 100 ᵒC) dryer type (hot-air convection vacuum) on some physical characteristics such as hectoliter weight, thousand kernel dimensions (thickness, length, width, equivalent diameter sphericity) corn during drying. Before drying, samples were pre-treated without (co...

The aim of this study was to evaluate the method producing shelf-stable snacks based on kiwifruit with objective obtaining an appealing snack good taste, color, and nutritional value. Less valuable kiwifruits for size shape were utilized in order reduce production waste. To obtain snacks, two drying methods used: freeze-drying hot air drying. Physical chemical analyses conducted. Furthermore, a...

In Central Europe the main species that are used for the production of sawn wood are spruce, pine, and European beech. After the sawing process, the sawn timber is technically dried to a certain moisture content by means of condensation drying. The water movement in the cellular structure, which is caused by the drying process, draws some of the extractives into solution. In the process of kiln...

ABSTRACT: In this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. Freeze drying is a separation process based on the  sublimation phenomenon. This process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...
