Energy-saving fruit drying room and drying method thereof

Abstract

The invention relates to the technical field of heat drying, and particularly relates to an energy-saving fruit drying room and a drying method thereof. Farmers adopt a natural airing method to dry fruits, but fruits have oil heads, dry strips, mildew and other phenomena, the fruits are attached by soils, are cracked and rotted worse if the fruits encounter severe weather, such as cloud and dust or cloud and raining, in harvest period. According to the invention, the fruits are dried with electricity or steam, thus the cost is high, the treatment capacity is small, and the efficiency is low. The energy-saving fruit drying room comprises a drying room, a heat supply device and a support, wherein the heat supply device and the support are arranged in the drying room. In the energy-saving fruit drying room, a heating fiery pit is arranged in the drying room, no energy is wasted, and the drying room is safe to use and cannot smoke drying objects; a fan is arranged above the fiery pit, andused for blowing hot air to the whole drying room, so that the dried objects are heated uniformly; a wood-grass-soil material in a damp absorption structure is arranged on a roof to naturally adjust the humidity, so that the quality is ensured, the drying efficiency is high, and the phenomena of oil head, dry strips or mildew in the natural airing process are avoided, the color of the fruits is good, and the processing is not restricted by weather.

Description

technical field [0001] The invention relates to the technical field of heating and drying, in particular to an energy-saving fruit drying room and a drying method. Background technique [0002] Fruits have high nutritional value and health functions. With the improvement of people's living standards and dietary structure, the demand for dried fruit food is increasing. There are also more and more foods that use dried fruits as raw materials. Fruit industries such as jujubes, walnuts, apricots and grapes have become pillar industries for rural economic development in marginal and impoverished areas. After drying and deep processing of Xinjiang Hetian fruit, it not only maintains the shape and nutritional value of the dried fruit to the greatest extent, but also makes the dried fruit easy to digest, delicious and easy to carry. It is a kind of food that is loved by people. The quality of dried fruit products largely depends on the drying technology. Because the drying of f...

AI Technical Summary

Problems solved by technology

At present, farmers in Hetian, Xinjiang use the natural drying method to dry fruits, which not only has a high moisture content, but also causes fruit oily spots, dry sticks, mildew and other phenomena, especially when fruit harvesting often encounters harsh continuous shade sand. Dusty weather or continuous rainy weather will aggravate clay, cracked fruit, and rotten fruit, which greatly reduces the quality and benefit of dried fruit, thus seriously affecting the enthusiasm of fruit farmers to plant and manage fruit trees

Electricity or steam drying treatment not only has high cost, small treatment capacity, low efficiency, but also unsatisfactory treatment quality, so it is difficult to popularize and apply in national-level poverty-stricken areas
