Food Dehydrators Dealers in Delhi

Drying (dehydrating) food is one of the oldest and easiest methods of food preservation. Dehydration is the process of removing water or moisture from a food product. Removing moisture from foods makes them smaller and lighter. Dehydrated foods are ideal for backpacking, hiking, and camping because they weigh much less than their non-dried counterparts and do not require refrigeration. Drying food is also a way of preserving seasonal foods for later use. Foods can be spoiled by food microorganisms or through enzymatic reactions within the food. Bacteria, yeast, and molds must have a sufficient amount of moisture around them to grow and cause spoilage. Reducing the moisture content of food prevents the growth of these spoilage-causing microorganisms and slows down enzymatic reactions that take place within food. The combination of these events helps to prevent spoilage in dried food. The preservation of foods by drying is based on the fact that microorganisms and enzymes need water in order to be active. In preserving foods by this method, one seeks to lower the moisture content to a point where the activities of food-spoilage and food-poisoning microorganisms are inhibited. Dried, desiccated, or low-moisture Resotech foods are those that generally do not contain more than 25% moisture and have a water activity (aw) between 0.00 and 0.60. These are the traditional dried foods. Freeze-dried foods are also in this category. Another category of shelf-stable foods are those that contain between 15% and 50% moisture and an aw between 0.60 and 0.85. These are the intermediate-moisture (IM) foods. Dehydrated products readily take up moisture when immersed in a liquid medium, leading to significant changes in their thermo physical properties. The rehydration kinetics, the structural properties (apparent density, true density, specific volume and internal porosity), the viscoelastic behavior (compression tests), and the flavor losses were the important parameters during rehydration of various fruits and vegetables. The effect of temperature on the above properties are also impact on some fruits and vegetables dehydrated by different drying methods (convective, vacuum, freeze, and osmotic drying).

Solar drying is in practice since ancient times for food and agriculture crops preservations. Before it was done generally done by open sun drying under the open sky.  Solar Dryer saves the food from rain, wind, moisture and dust, loss of material due to birds and animals, worsening of the material by decomposition, insects  and fungus etc . Thus solar drying equipments is the best option for  over coming all sort comings of natural drying and artificial motorized drying. Aspes Solar dryers are used in agriculture food and crop drying, for industrial drying process, as they saves lot of electricity, heat energy and money . It not only save energy but also save lot of time, also occupies less area, protects environment, make the  process more capable and also improves value of the product. Solar drying system overcomes some of the major disadvantages of usual drying process.  Solar drying can be used for the total drying process or  for backup to  artificial  drying systems in any industry,  thus reducing  the total amount  of fuel  energy required earlier for drying things. In an integrated solar dryer solar energy collection and drying take place in a single system. There are various types of solar dryers Cabinet dryers, Rack dryers, Tunnel dryers, Greenhouse dryers, and multi-rack dryers. Solar dryers are small in size and are stand-alone units but can be customized and made as per requirement for industrial application where they save huge fuel & money, risk & labor. Advantages of solar drying system Solar drying systems have low operation and maintenance costsSolar dryers are more economical compared to dryers that run on conventional fuelelectricitySolar dryers last longer. A typical dryer can last 15-20 years with minimum maintenanceThe drying process is completed in the most hygienic and eco-friendly way Aspes Solar Dried Food benefits "Dried foods are tasty, nutritious, lightweight, easy-to-prepare, and easy-to-store and use. The energy input is less than what is needed to freeze or can, and the storage space is minimal compared with that needed for canning jars and freezer containers. "The nutritional value of food is only minimally affected by drying. Vitamin A is retained during drying; however, because vitamin A is light sensitive, food containing it should be stored in dark places. Yellow and dark green vegetables, such as peppers, carrots, winter squash, and sweet potatoes, have high vitamin A content. Vitamin C is destroyed by exposure to heat, although pre-treating foods with lemon, orange, or pineapple juice increases vitamin C content. "Dried foods are high in fiber and carbohydrates and low in fat, making them healthy food choices. Dried foods that are not completely dried are susceptible to mold. Drying is one of the important and most energy consuming processes in the food processing, chemical, printing, fabric dying industries, etc In farmer level drying is being done on open yards without any good hygienic conditions. Generally thermal energy, (hot air) is being used to dry the required products. Temperature of the air is maintained between 450C to 2500C depending on the products and production methods. That energy is being produced by a conventional fuels like electricity, firewood, diesel, furnace oil, kerosene, etc. The cost of the conventional fuel is increasing day by day, as the availability of the conventional fuel in the earth is decreasing day by day. Domestic use or application of solar drying system Drying of any agricultural products like grains, crop, vegetables, fruits, cocoa, tea leaves, nuts and beans before storingFish and other seafood dryingDrying of raw cotton, herbs, tobacco, spices etc Aspes Solar Dryer are useful for commercial or industrial manufacturing purpose as below Solar dryer are used for drying Herbal products, washed wet cloths, seasoning wood and timber, drying latex, in dairy industries for production of milk powder and casein, in laundry, in textile industries, drying leather, drying mattress, finished goods, color paint on finished products, Coffee processing, food processing  industries  for  dehydration  of  fruits and vegetables like potatoes, onions and other vegetables cotton ginning, saw milling, furniture works and brick making, are primary industries. The coffee processing and the cotton-ginning.
