Drying belt 630 floats above a heated medium flowing in a trough 640, according to one embodiment. According to another embodiment, one trough per chamber is used where the temperature of the water in each trough is independently controlled. Spray-drying techniques apply heat to raw material ranging from 150°C to 300°C. Both methods can cause significant nutritional loss to the raw material being dried. Compare Hydro Dri™ dried product quality to freeze-drying and spray-drying.
Unlike certain other drying technologies, RW™ drying does not require high operational pressures. Also, there is limited scope to oxidation and free radical formation and RW™ dried products offer improved shelf life. Refractance window drying is a cutting-edge modern-day food production technology. It is followed by the leading food suppliers in India.



The connection between drying chambers 610 and 620 may be provided by adhesive, locks, sealants, covers, or other attachment mechanisms, according to some embodiments. A continuous belt 630 may be directed through all of the drying chambers guided by rollers . These rollers move drying belt 630 in a continuous loop from one end of drying chamber 610 to the opposite end of drying chamber 620 and back again.
Wherein the air flow from the conditioned air supply manifold to the exhaust manifold is above the belt and in a direction countercurrent to a direction of travel of the product on the belt. Such a design promotes the short circuiting of air, making for inefficient use of the full moisture carrying capacity of the air that was short circuiting. Thus, the design failed to effectively distribute the air across the entire width of the belt. Refractance Window Dryer Furthermore, the traditional drying system increases water vapor pressure in the product by increasing the product temperature due to thermal energy conducted from the body of heated water through the drying belt. However, the traditional drying system does not reduce water vapor pressure, increase the temperature of air within the dryer, or reduce the humidity of air within the dryer, all of which can improve dryer performance.

Food Tech Projects is one of the reputable sources where you can purchase this machinery for your food processing and supplying needs. We are one of the leading manufacturers of refractance window dryer. With our machinery, it will be possible for you to manufacture different food items without altering their nutritional benefits. The method of claim 10, wherein the drying belt floats on a heated medium configured to heat the product, and wherein the heated medium is maintained at a pre-determined temperature. The method of claim 10, wherein an exhaust fan assembly directs the conditioned air out of the drying chamber through the exhaust manifold. 6 illustrates a cross-sectional view of two exemplary drying chambers 610 and 620 connectable by way of the discharge end 625 of one chamber and the opposite end 615 of the other chamber, according to one embodiment.
However, the dehydration process can destroy some of the food’s nutritional value. It was composed of two separate. Consider doing a theme themed dinner parties are. Web the american harvest, or harvest maid food dehydrator is a home appliance used to dry fruits, vegetables and meats. The system of claim 1, wherein the air flow is parallel to the direction of travel of the product on the belt. The method of claim 14, wherein the filtered air system is an HVAC unit with a cooling capacity and a heating capacity.

Drying is an energy intensive unit operation, accounting to around 12–20% of the total energy consumed in the manufacturing industry (Raghavan et al., 2005). Nevertheless, dried products are more stable to microbial contamination and other deteriorative chemical reactions, apart from facilitating storage and minimizing transportation costs. It does not directly expose the food to extreme hot or cold temperatures.

Trough 150 may include a pump to recirculate the heated medium between a heating tank and the trough 150. Dryer 100 includes a single trough 150, however multiple troughs may be used, with each trough having its own air supply manifold 120 and exhaust manifold 130. In alternate embodiments, multiple troughs share a single air supply manifold 120 and exhaust manifold 130. According to one embodiment, dryer 100 may be one chamber in a multi-chamber dryer. In a multi-chamber dryer system, a single drying belt 110 spans across all of the drying chambers effectively doubling, tripling, etc. the length of the drying belt 110.
