H in hybrid drier, against 72–120h in ‘solar-only’ operation of the same drier and 192–288h in open sun. Efficiency of the drier during its two mode of operation has been estimated and quality evaluation of under-studied products showed that developed drier is suitable for the drying of these products. The developed drier is a simple system, which can be manufactured locally and can be used for drying of other agricultural products. Eight experimental tests were conducted between September 15 and November 30, 2014.
Solar energy can be used in three different ways for the drying of a product as shown in Fig. Drying is a complex process involving simultaneous heat and mass exchanges, and it is considered one of the oldest unit operations performed for preserving agricultural products. This process requires a significant amount of energy, and researchers have conducted different studies to improve energy efficiency, reduce drying time and preserve product quality. Dryers based on solar energy have gained more space, as this energy source is free and abundant. Thermal energy storage techniques can increase the reliability of solar energy for drying.
Drying is an extremely important process in ginger processing, and it is also the most energy-consuming stage. The traditional ginger drying is mostly roasted by coal-fired steam boiler, which is polluted and expensive to manage. With the popularization of low-carbon energy-saving trend, it is very urgent to study a new type of ginger drying model. The development of a new energy-efficient drying equipment has become a trend. Therefore, our company successfully developed a new ginger drying equipment-heat pump ginger dryer. In this study, a prototype of a passive-cum-active dryer with a biomass fired-heater and a plate heat exchanger was developed and tested.
Then, fill the pot with the soil, leaving about 1 inch (2.5 cm) of space at the top, and plant the ginger 2 inches (5.1 cm) beneath the surface, laid horizontally. Cutting your ginger root into pieces allows for more opportunity to plant and grow a successful ginger plant. Keep the ginger plants at about 68 °F (20 °C) in direct sunlight, and apply liquid fertilizer once every few weeks. We are manufacturing and exporting an exclusive range of products like Vegetable Dryer, Fruit Dryer Machine, Herbal Drying Machine, Spices Dryer Machine, Food Dryer Machine.
An et al. explored the effects of partial drying methods on drying of ginger, and concluded that the combined drying process is better, as it can provide a theoretical basis to conduct relevant experiments. The most common dehydration method is hot drying , however, its prolonged hot air convection could result in the decrease of vital nutrients. To overcome the aforementioned challenges, a new drying method, catalytic infrared drying is attracting keen interest in recent times. Therefore, in this study, it was applied in Ginger Dryer the drying of ginger with high moisture content, and compared with other drying techniques such as hot air drying, freeze drying and vacuum drying. Furthermore, the CID has been reported to save approximately 60–70% of the energy consumed by the electric infrared drying method and 20–50% of the energy consumed by the hot air drying method (Feng et al., 2019). Prior to drying, crops at suitable maturity are generally prepared by cleaning, sanitizing, sorting, peeling, trimming, and cutting (Mühlbauer and Müller, 2020).
Vermiconversion possibility of waste biomass of two medicinal herbs Zingiber officinale and Curcuma longa has been investigated. The Eisenia fetida, an epigeic earthworm was used in the vermicomposting process. The vermicomposting caused shifting in pH towards neutral range, reduction in electrical conductivity, total organic carbon, C/N and C/P ratios whereas1.8–2.73 folds enhancement in macronutrients and ash contents in the substrate mixture.
The tests were performed at 95% confidence level with p-value equal to 0.05. Various research works have been focused towards increasing the drying rate through the use of thermal storage system , auxiliary heating devices [, , ] and porous collector and recycling of the exhaust gas . The ginger powder processing line can be equipped according to the user's requirement and the production demands. In modern India, ginger is widely cultivated and marketed as a dried spice, and India has a predominant position in ginger production and exports.
In addition, blocking the tumor promoter–induced activation of AP-1 inhibited neoplastic transformation (Dong et al. 1994). Epidermal growth factor is known to induce a relatively high level of AP-1 activity and cell transformation . We previously investigated the effect of two structurally related compounds of the ginger family, -gingerol and -paradol, on EGF-induced cell transformation and AP-1 activation (Bode et al. 2001). Our results provided the first evidence that both compounds block EGF-induced cell transformation, but by different mechanisms. -gingerol appeared to act by directly inhibiting AP-1 DNA binding activity and transactivation, whereas -paradol appeared to act by inducing apoptosis (Bode et al. 2001).
Alavi, “Effects of grain drying methods onpostharvestinsect infestation and physicochemical characteristics of maize grain,” Journal of Food Process Engineering, vol. The efficiency of a solar collector is defined as the ratio of the useful energy gain to the incident solar energy. Drying temperature and airflow rate as a function of time. Where is the moisture content at wet basis (kg/kg) of wet product, is the weight of the wet product , is the weight of the dry product , and is the moisture content on a dry basis (kg/kg) of the dry product.
When you say the hearts “are still good”, I assume you mean they look the same and aren’t showing obvious spoilage. Even with commercial products, it’s best to use them within a month or two of opening a container for best quality. At nearly a year old, freeze dried or not, those hearts are no longer at best quality. The problem is that the oils that cause the off flavor are now coating the entire vacuum chamber of your freeze dryer, and likely the drain hose, too.
Preparation of dried & preserved ginger is discussed in detail along with its benefits. Xiao, N.; Xu, H.; Jiang, X.; Sun, T.; Luo, Y.; Shi, W.

Apart from all these benefits, ginger also improves cholesterol levels, helps with heart health and improves cognitive functions. Anti-emetic and nausea properties – this spice has been in use for reducing nausea caused by poor eating habits, morning sickness, motion sickness or even chemotherapy. Better metabolism – when your body has a high metabolic rate, you will be able to lose weight or at least not put on excess weight. Most ginger ales do have at least a small amount of ginger in them.
It leads to reduce the water activity in the product and thereby prolongs its shelf life by decreasing the microbial contamination. Thymus satureioides, a medicinal and aromatic plant, was conserved using a nondestructive innovative preservation process integrating sustainable energy. The process is based on a combination of pretreatment by aqueous solutions of natural organic acid followed by a partial solar convective drying. Therefore, it is overridden to understand the mechanisms influencing the treated thyme drying process compared with the drying kinetics of witness thyme. The effect of drying conditions (season, temperature ranging from 50 to 80 °C and drying volume flow rates of 150 and 300 m3/h) and the pretreatment conditions on the process efficiency were studied. Furthermore, the effects of temperature, season, drying volume flow rates and citric acid on drying rate and total phenolic content were also investigated.
