Scanair found solutions for drying applications with Low/High Temperature Process drying dehumidifier dryers.
SCANAIR dehumidifier dryer in india is specifically designed for use in high temperature process drying applications. The unit can operate in temperatures up to 80˚C. Used in conjunction with a scanair process drying control panel to create the perfect drying environment for your product. we also manufactures a standard range that can operate at up to 40˚C to 60˚C which have also been used successfully in many process drying applications.This machine fits for drying and sterilizing powder, granular, sheet-like or gel-like food, and additive, flavoring, medicine, raw material of herbal medicine, nutritional health products, agriculture & sideline products, non-fried (or oil-saving) instant noodles, noodles, rice powder noodles, soya products, pepper, mushroom, radish, amber, onion fruits, herbs, wood, drugs, beef jerky, preserved meat, dried fish, tea, tobacco, peeling and baking almond, peach kernel, groundnut kernels, pachyrhizus chips, potato chips, dried shrimps, fish, variety of small packaging food, drying beans and for drying and desulfurization and deoxidizing the metallurgical chemical products and for drying printing and dyeing products, ceramics, glass, chemical fiber, cotton yarn, wood, leather, bamboo products, insulation materials, building materials, cork, corrugated cardboard etc,.
Dehumidifier dryer Conduct drying by keeping the Quality, Fragrance, Color and Flavor with high efficiency, eco friendly, Innovative drying performance energy consumption rationalization facility funds support 50~60% of energy saving comparing to general dryers, Drying by ripening program High performance Drying Natural drying effect due to low temperature dehumidification. Low temperature dehumidified air is used for drying? Quality, fragrance, color, flavor is preserved in its natural state and precise control of air passing amount through condenser and evaporator? Stabilized compressor operation and maximum dehumidification eco-friendly System Reduced contaminated air exhaust due to use of semi airtight type circulation – Pleasant working environment maintained – No emissions caused by combustion Innovative energy conservation Utilization of air heat energy and recycling of heat. – 70% cost cut down compared to oil dryer – 60% cost cut down compared to electric heater dryer Adaptability Applicable to general purposes and can be applied without being affected by seasonal changes because it is not affected by exterior temperatures.
A new generation scanair dehumidifier dryer of low-temperature drying process – cold dried
air is used for food, chemical, pharmaceutical, hygroscopic products, vegetables, etc, the preferred drying processing equipment, the cold air dryer dried foods not only to maintain the original quality, and easier to package, storage, and transportation cold air dryer for drying all kinds of high quality, uniform and other food and vegetables and herbs. Control temperature& humidity technology and its performance can be comparable with similar natural way drying products. Environmental control air temperature 30-35 degrees Celsius with Dehydrating effect, Drying process material no deformation, no cracking, no – discoloration, no deterioration, and no oxidation, no distortion, especially for fish and shrimp, fish, river fish, dried shrimp, abalone, sea cucumber, shark, squid, fish and other seafood drying dehydration.
Kinds of automatic modes of operation: 1. Temperature drying mode – in hot and humid environment, the unit automatically run dry and cool mode, the unit heat generated by the cooling water discharged to the atmosphere. 2. Thermostat drying mode – in the temperature meet requirements, the thermostat dry, dry air under constant temperature conditions. 3. Heating drying mode – at low temperature cold, damp environment, the unit automatically heated drying mode, does not reduce the indoor temperature to dry.
Most rice dryers working on heating the air for drying process, blowing the air through wet rice paddy to evaporate water from the rice. This process requires large amount of energy to supply the heat for water evaporation as well as to heat the air, which is used as the carrier. The performance of traditional dryers depends heavily on ambient conditions, especially ambient relative humidity. On a summer days, a batch of rice can be dried in six to ten hours. On a rainy day, it could well take three times as long and three times as much the energy consumption.
The drying system presented today is a complete departure from the traditional way to build a dryer. This system uses two technologies to achieve the task we made the unit dry air out of wet air, and make heat out of humidity. Dehumidifier heat pipes are used to produce dry air, and a latent heat scanair heat pump is used to produce low cost heat energy, from the very high humidity ambient air.
Drying by dehumidification is the most effective, energy efficient and economic way to dry your products
There are several limitations associated with traditional sun drying. During periods of intermittent and particularly during continuous rainfall, fish, meat, sea foods, drying is not possible and the risks or material losses are high. Sun drying is slow and weather dependent compared the other alternative drying systems. Dry fish quality may be low due to contamination by dust, dirt, stones and insects, while direct crop losses from theft and livestock consumption can be high. Sun drying also suffers from a high labour requirement and excessive material handling particularly in periods of inclement weather which can result in high costs, material damage and a loss in quality. Since good design is essential for the long-term reputation of the technology, scanair shall be addressing ourselves to installers, manufacturers and consulting engineers.
A bacterium requires a high humidity to survive and to multiply if the humidity level of the surrounding air is kept below 40% RH most bacteria will not survive. The limit is especially important when drying fish, meat, dry sea food, products which are susceptible to bacteria.
Scanair dehumidified dryers operates according to a basic air conditioning cycle involving four main components: the evaporator, the compressor, the condenser and the expansion valve etc,.
