Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of preserved fruits, and particularly relates to a drying and dehumidifying system for cranberry preserved fruits. BACKGROUND

[0002] Cranberry is a kind of nutrient-rich berry, and the pulp contains rich proanthocyanidins, tannic acid, phenolic acid, resveratrol and other substances, and has antibacterial effect. Many studies have shown that cranberry can inhibit the infection of helicobacter pylori, and has good effect on preventing gastric ulcer, gastric cancer and duodenal ulcer. In addition, flavonoids in cranberry have antioxidant function in in-vivo and in-vitro experiments, and flavonols and proanthocyanidins have a preventive effect on atherosclerosis. Cranberry also has the functions of lowering blood pressure, preventing urinary tract infection and preventing cardiovascular diseases, and has many health care functions such as lubricating the intestines, relieving constipation, reducing cholesterol and resisting viruses, so it has been more and more popular among consumers. However, due to the limitation of cranberry production area and the difficulty of shelf period and preservation, cranberry is more likely to enter the consumer's field of vision as cranberry dry and cranberry juice.

[0003] At present, there are mainly three kinds of preserved fruit drying processes: hot air drying process, microwave drying process and solar drying process. The microwave drying process has high power consumption and strong damage to fruit molecules. Although the solar drying process is energy-saving and environmentally friendly, it is greatly affected by weather factors and is more suitable for large-volume preserved fruits. The hot air drying process is the most traditional and widely used in time and scope.

[0004] Chinese patent CN103211002A discloses an air energy heat cycle preserved fruit drying device and an automatic temperature control method thereof, which comprises an air energy heat pump, a dehumidifier, an oven and a heat transfer pipeline. By cooperating with multiple ovens and adopting a serial heat transfer pipeline drying process, the function of single heat source for simultaneous drying of multiple ovens and multiple varieties is realized. However, it needs manual transportation and uniform spreading of preserved fruits, which is labor-intensive, low in efficiency and not suitable for drying small-volume preserved fruits.

The two sides of the oven body are respectively a first air drying end and a second air drying end. The oven body is provided with a fan with an air inlet and an air outlet on the two sides. The mounting plates close to the first air drying end and the second air drying end are provided with a plurality of ventilation openings at different positions, so that the air entering and leaving the oven body is more uniform, and the preserved fruits are more uniformly dried. However, it also needs to use a drying cart to send the preserved fruits to be dried into the oven, and then manually spread them, which is labor-intensive and not suitable for drying small-volume preserved fruits.

[0006] Due to the increasing attention to food safety, the traditional oven type rough drying method is not suitable for the production of factory candied fruits, and due to the high sugar content of candied fruits, although it is not conducive to the growth of microorganisms, it is still necessary to pay attention to the drying equipment and air quality to reduce poor pollution. In addition, in order to ensure the uniformity of drying, it is necessary to turn the candied fruits regularly to avoid sticking and uneven drying, and the artificial turning efficiency of cranberry candied fruits is low, and the uniformity of turning cannot be guaranteed. Therefore, it is necessary to design a drying device suitable for factory production, high cleanliness, high automation and small volume candied fruits. Practical new type content
