Problems solved by technology

Beach drying or natural beach drying on a cool shelf has a long drying cycle and is easily affected by rainy weather. Rot and browning are prone to occur during the drying process, which affects the quality and grade of dried fruits
The drying method of the drying room heated by coal-fired hot blast stove has the disadvantages of high energy consumption, large fluctuations in drying temperature, unsatisfactory color of dried apricots and air pollution by soot

Embodiment Construction

[0009] Put 800 kg of fresh apricots with a moisture content of about 76% into 80 trays (bamboo curtains are laid on the inner bottom of the trays), spread one layer, then put them on the shelf of the greenhouse drying box, and then carry out three consecutive stages of drying. Drying process:

[0010] ①Introduce hot air, adjust the amount of steam, the air intake volume of the air supply fan and the exhaust air volume of the dehumidifier, so that the temperature of the intake air is kept at 48-55°C, and the relative humidity of the exhaust air is kept at 28-32% for 30 hours;

[0011] ②Adjust the amount of steam, the air intake volume of the air supply fan and the exhaust air volume of the dehumidifier fan, so that the inlet air temperature can be maintained at 55-60°C, and the relative humidity of the exhaust air can be maintained at 32-36%. After 6 hours of this drying process, cut off the hot air supply, open the dehumidifying fan and the air inlet, pass in normal temperatur...

Abstract

The invention provides a novel technology for drying apricot by combining the solar energy heating and the vapor heat energy heating, and combining the solar radiation drying and the hot blast convection drying. The drying processing of the apricot is divided into three steps, and the parameter such as dying temperature, humidness, etc. of each step is provided. The drying process cycle of the drying process is short, the energy is saved, and the dried apricot has the advantages that the color is golden, the taste is pure, and the quality product rate is high.

Description

(1) Technical field [0001] The invention belongs to the field of fruit drying and relates to a new technology for drying apricots by combining solar energy and steam heat energy for heat supply. (2) Background technology [0002] Dried apricot is the dried fruit of apricot. The quality of dried apricot is not only related to the variety of fresh apricot, but also depends on the drying process of apricot. During the drying process of apricots, it is not only necessary to remove the moisture in the material to achieve a safe storage moisture content, but also related to the color and taste of the dried apricots. At present, there are generally two methods for drying apricots, one is drying on the beach or drying on a cooling rack, and the other is drying in a drying room. The hot air is provided by a coal-fired hot air stove and sent into the drying room by a blower. . The method of beach drying or natural beach drying on a cool shelf has a long drying cycle and is easily af...
