What your microwave oven did for your kitchen, radio-frequency drying can do for your process. Radio-f requency (RF) drying is increasing in popularity in the textile industry because it is fast, effective, and economical. This bulletin will review the benefits of using RF to dry yarn packages. RF dryers can also dry most other textile products, including loose stock, hanks, muffs, cones, tops,...

In this study, response surface methodology was used for optimization of intermittent microwave-convective air drying (IMWC) parameters with employing desirability function. Optimization factors were air temperature (40-80°C), air velocity (1-2 m/sec), pulse ratio) PR ((2-6), and microwave power (200-600 W) while responses were rehydration ratio, bulk density, total phenol content (TPC), color ...

Background: Drying is the most common way to preserve quality of aromatic and medicinal plants. Chosen drying methods can affect on the essential oil content and composition of medicinal plants. Objective: This study aimed to assess the changes in essential oil constitutes of catnip aerial part under various drying methods. Methods: The experiment was performed as the randomized complete ...

Microwave is the machine, which is very helpful for the food sector. The modern age of life as well as the increasing number of working women requires simplified routines and standardization of foods with lesser preparation time and convenience in usage. The demands of the consumers are the real factor for the success or failure of any food items in the present scenario. The increasing consumer...

In recent years, the rapid growth of chilled and frozen food market is due to rapid reheating instruments such as domestic or commercial microwave oven as well as conventional ovens. The goal of these products manufacturers is to cook the products to a temperature that would ensure the reduction of pathogenic bacteria to a safe level. It is a common way to heat the chilled foods in a microwave ...

The quality of microscopic image of cryostat sections that had been subjected to microwave assisted fixation was compared with that resulting from conventional air drying of the sections. The role of microwaves in producing rapid special stains on cryostat sections was also assessed. Methods used permitted stains such as periodic acid Schiff, alcian blue, Gordon and Sweets's reticulin, Masson F...

A peer-verified method is presented for the determination of percent moisture/solids and fat in dairy products by microwave drying and nuclear magnetic resonance (NMR) analysis. The method involves determining the moisture/solids content of dairy samples by microwave drying and using the dried sample to determine the fat content by NMR analysis. Both the submitting and peer laboratories analyze...

Ten laboratories participated in a collaborative study to determine the total moisture and fat in raw and processed meat products by microwave drying and nuclear magnetic resonance (NMR) spectroscopy. Meat products were prepared following the AOAC Method and analyzed using CEM Corp.'s SMART Trac Moisture and Fat Analysis system. SMART Trac provides moisture results by measuring the weight loss ...

Microwave heating–drying of wood using a wave guide is a relatively new area of research. In order to gain insight into the phenomena that occur within the wave guide together with the temperature distribution in the wood, a detailed knowledge of absorbed power distribution is necessary. In this paper, a two dimensional numerical model is developed to predicted the distribution of electromagnet...
