Cold-air dryer for preserved fruits

Abstract

The invention discloses a cold-air dryer for preserved fruits. Existing drying equipment includes a heating dryer, a freeze dryer, a vacuum dryer, an infrared dryer and the like, and realizes drying by heating or freezing. Fruits contain glucose, fructose, cane sugar, cellulose, vitamin, pigments, enzyme, water and protein which are sensitive to temperature, the preserved fruits is hard in texture and poor in taste due to low temperature, and effective components in the preserved fruits are destroyed at over-high temperature, so that the preserved fruits change color and flavor and lose all flavor. Under the combined action of an air conditioner, a fan and a dehumidifying device, the preserved fruits are dried at the temperature not higher than 37 DEG C, the temperature in the whole drying process is similar to the room temperature of Chinese southern China, the effective components in the fruits are not destroyed, and the flavor of the fruits is kept.

Description

technical field [0001] The invention relates to a cold air dryer for preserved fruit, which belongs to the technical field of fruit deep processing equipment. Background technique [0002] Fruits in southern my country generally have a concentrated ripening period, a large number of concentrated and mature fruits, and the fruit shelf life is short. When the fresh-keeping technology is not very mature, it is a good way to increase the added value of fruits. . As we all know, the key technology for the preparation of preserved fruit is drying, and the drying quality directly affects the quality of preserved fruit, because the quality of preserved fruit is related to the water content, appearance, color, mouthfeel, flavor, hygienic index and texture of preserved fruit. Therefore, preserved fruit The drying of dried fruit is crucial for the production of preserved fruit. Existing drying equipment is nothing more than heating dryers, freeze dryers, vacuum dryers, infrared dryers...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a cold air dryer for preserved fruit, which overcomes the deficiency that traditional dryers cannot dry fruit reasonably and effectively. Through the present invention, the comprehensive quality of preserved fruit can be improved, and the quality of preserved fruit can be raised to a higher level.
