Создание И Исследование Гелиотехнологической Установки С Поликарбонатным Покрытием

The proposed solar dryer (S / D) has a polycarbonate coating, which is actually a combined dryer. By drying an agricultural products in the proposed apparatus, it is possible to get ecologically pure and high quality food. The "greenhouse effect" in S / D ensures the temperature under the glass is 15-25°C, higher than the ambient temperature. In windy weather, the product to be dried cannot be left in the open air due to strong winds, in this device drying in windy weather occurs no less intensively than in hot weather, although the air temperature in S / D is not high. During wind it is recommended to locate the S / D with the inlet towards the wind. The high drying speed occurs due to the increased convective movement. The wind creates a fan effect both at the inlet S / D and at the outlet - at the end of the pipe. In the proposed installation, it is possible to dry various agricultural products, both in direct sunlight and without them

Development and Testing of A Polycarbonate-coated Solar Installation for Drying Agricultural Products

The proposed solar drying system significantly reduces the drying time and improves the quality of the product, including the preservation of vitamins. When drying rosehip, a laboratory analysis for vitamin "C" showed that 28% of this vitamin is destroyed during natural drying, and 17% when using a solar dryer.The drying speed increases by 2.5 - 4 times compared to traditional outdoor drying.In the proposed installation, you can dry different agricultural products, you can change the coating of the solar drying unit. In S/D, the air temperature is higher than in the environment from about 13 to 32 degrees Celsius, depending on weather conditions.The drying process in the S/D apparatus allows you to ensure the purity of the products. S/D is covered and during the drying process the product is not contaminated with dust and rain, by influence of dew, is not damaged by birds, insects or wasps.This device is convenient for transportation, during the day it can be moved and rotated to align to the sun.The proposed solar dryer is easy to manufacture and can be widely used in large and small farms, private and subsidiary farms
