Tray Dryer for Food Drying
Tray Dryer play a major role to obtain a high quality dried product, fruits, vegetables and meats need to be prepared before drying. Good preparation practices are a prerequisite for the final dried product quality. Fruits and vegetables must be washed prior to drying to remove soil and other foreign materials. Damaged parts must be removed. Fruits and vegetable should be peeled and cut into small, uniform pieces. Fish should be scales should be removed and in some cases skinned before cutting into uniform pieces. The smaller the food piece, the faster it will dry. Selecting the appropriate temperature for drying is very important for good product quality. Too high temperatures can lead to product darkening, discoloration, case hardening, and cooking. Too low temperatures can lead to slow drying and food spoilage. A good, safe temperature for drying many foods is 40 – 60˚C. However this must also be accompanied by good air movement through the tray dryer.
Drying is an energy intensive process which involves the removal of moisture from the product until the moisture content of the crop is in equilibrium with the surrounded air, Try dryers are the most effective solution as crops are usually dried to a moisture content that will allow safe storage and or further processing like Milling. The drying behavior of different crops depends to a large extent on the physical characteristics of the crop for example particle size, internal structure and composition. These characteristics are the crop specific, and so the drying behavior of crops is usually different. In order to select an appropriate dryer and the drying parameters such as drying time and temperature and humidity level will determine moisture loss characteristics, physical and biochemical changes of specific crops, it is an important mater to understand the drying behavior of the material to be dried.
There are several limitations associated with traditional sun drying, where try dryers with it’s own advantages comes to the rescue. During periods of intermittent and particularly during continuous rainfall, crop drying is not possible and the risks or crop losses are high. Sun drying is slow and weather dependent compared to other alternative drying systems. Crop 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 crop handling particularly in periods of inclement weather which can result in high costs, crop damage and a loss in quality.
