Its main working principle is to spread the material evenly in the network. The material is moved in the dryer by the operation of the machine, and the hot air draws out the water vapor of the material. If we use the ginger drying oven, the equipment is equipped with a small cart with a tray and a tray rack. The heat in the air is absorbed by the heat pump compressor. After compression and release, a large amount of high-temperature hot air can be obtained, so as to realize the continuous and uniform drying and processing of ginger. Sichuan Shouke Agricultural Technology Co., Ltd., was established in 2002 and can provide pepper dryer, condiment dryer, onion dryer, ginger dryer, fruit dryer, coconut shell dryer and other large-scale drying equipment.
The problem with a single inlet solar dryer, especially in natural convection, is that the air is not well distributed along the trays, resulting in the non-uniform moisture content of the final product. The demand for herbs and spices is increasing with the population and turmeric is one of major herb in that. Traditional way of turmeric production is use to produce turmeric but there are many inefficiencies in that process as well as it is lagging somehow to fulfill demand. So there is a need to study the traditional method and to identify the effect of various parameters on turmeric production.





-dehydroparadol (75 μM) was more potent than the other compounds tested, and it induced apoptosis through a caspase-3-dependent mechanism (Keum et al. 2002). Structure of -gingerol, believed to be the most abundant bioactive component of ginger root. After drying the rhizomes are polished by rubbing with a coarse cloth to remove all bits of skin or dirt. The peeled rhizomes are washed & sundried for 3-4 days on cement floor. Table 2.Quality parameters of ginger dried at different temperatures, thicknesses, and loading densities.
Convective heat transfer coefficient of ginger slices showed changes in ranges 0.33–2.11 W/m2°C. The heat energy and electricity required for drying process are provided entirely by solar energy and wind energy. In this paper, the drying kinetics, colour parameters, microstructure, thermal stability and ginsenoside contents of different parts of Panax notoginseng dried using the drying system and open sun were studied.

Basically, there are four types of solar dryers; direct solar dryers, indirect solar dryers, mixed-mode dryers and hybrid solar dryers. This paper is a review of these types of solar dryers with aspect to the product being dried, technical and economical aspects. Ginger Dryer The technical directions in the development of solar-assisted drying systems for agricultural produce are compact collector design, high efficiency, integrated storage, and long-life drying system. Air-based solar collectors are not the only available systems.
The drying behaviour and heat transfer coefficients of ginger dried in a convective dryer was analysed by Akpinar & Toraman . The drying curve was fitted with various models, and it was found that the Midilli and Kucuk model showed best fit. The estimated convective heat transfer coefficient values were in the range between 0.33 and 2.11 W m−2 °C−1. A comparison of the drying behaviour of potato dried in an indirect and mixed solar dryer was reported by Djebli et al. .

For every tablespoon of fresh ginger your recipe calls for, substitute ¼ teaspoon of cinnamon. For every teaspoon of fresh ginger your recipe calls for, substitute 1 teaspoon of nutmeg. For every tablespoon of fresh ginger your recipe calls for substitute ¼ teaspoon of allspice. For every tablespoon of fresh ginger, you will need to substitute 3 tablespoons of minced crystallized ginger.
Furthermore, the review article also reviews the economic assessment and thermal energy storage based solar drying of such products carried out by a few researchers. Singh et al. carried out experiments in the solar dryer for drying Fenugreek leaves. The ascorbic acid, total chlorophyll content, and color of the dried samples were found to be better compared to open sun drying. Bahammou et al. investigated the solar drying process of Rupturewort .
As it ferments, beneficial bacteria and yeasts grow and produce natural carbonation. This traditional method of drying ginger is economical and does not require any investment. However, because the drying effect is greatly affected by the environment and is not easy to control, the drying color of ginger is uneven, and even defective ginger may appear. During the drying process of ginger, a certain amount of manual turnover is required. Lantian Machinery Factory specializes in the production and sale of ginger slice dryer for more than ten years.

With the popularization of low-carbon energy-saving trends, it is extremely urgent to study a new ginger drying mode. The traditional 10,000-ton ginger drying line has an annual coal consumption of about 2769 tons of coal. The annual operating cost of the light drying section is about 2.8 million yuan. At the same time, a large amount of polluting gas is generated, which is gradually controlled by the state. Therefore, it has become a trend to develop a new type of energy-saving and environmentally-friendly high-efficiency drying equipment. Compared with traditional drying, heat pump drying has significant energy saving effects, and the drying quality of dried materials is better maintained.
The possibilities are only just beginning and the freeze drying is young only slowed by the lack of imagination on our part. Your knowledge is founded in your pursuit of different ways to accomplish your goal in food preparation. I too am new to the freeze drier and love it’s simplicity and It’s possibilities.

Optionally, transplant your ginger as the seasons change. While not required, ginger benefits from some time outside its pot. Once the weather is consistently above 50 °F (10 °C), carefully dig your ginger out of its pot and plant it in your garden. Select a sunny spot with loamy soil similar to its potting soil, and plant the sprouts 3 in (7.6 cm) deep and about 12 inches apart, out of the wind.
The finished food will absorb moisture like a sponge, which could give it a chewy texture if it’s not store properly and quickly. If you’ve set your freeze dryer up correctly, the front will be set higher than the back in order to facilitate runoff of water during defrost cycle. In order to get around this problem, simply place the trays into your home refrigerator freezer and pre-freeze then load those pre-frozen trays into your freeze dryer. Drying time will vary by hours for the same food under different conditions. If there’s too much ice built up on the unit, it can interfere with drying, so it’s generally not recommended to run two cycles back to back without the thaw.
The operation of this all-in-one drying equipment is relatively simple, and drying can be carried out only by plugging in the power supply. Pest control in stored grain crops in southern Africa is largely dependent on the use of phosphine generating fumigant, aluminium phosphide , albeit using blanket dosages, regardless of storage system type. Fumigation failures were 320% higher in compacted gravel than concrete floor platforms. Cryptolestes ferrugineus , Prostephanus truncates , Rhyzopertha dominica (Fab.), Sitophilus zeamais and Tribolium castaneum were common insect pest species across GMB depots. Aluminium phosphide dosage had differential effects on pest species with 95% mortality of C.
