Description

Technical Field

[0001] The utility model relates to the technical field of dried fruit dryers, in particular to a dried fruit dryer capable of detecting moisture content. Background Technique

[0002] Dried fruits are low-moisture-content foods made from fresh fruits through sun drying or drying, and are used for direct consumption or for making compound foods. During the drying process of dried fruits, dryers are mostly used for drying. Among them, due to quality assurance factors, the moisture content of dried fruits needs to be strictly controlled. Too low moisture content affects the taste, and too much moisture is inconvenient for storage. Therefore, before the dried fruits leave the factory, it is necessary to detect the drying degree of the dried fruits. For the moisture detection of dried fruits, usually spot checks are carried out on the dried fruits, and it is impossible to directly detect the dried fruits during the drying process of the dried fruits. It is easy to have the situation that the drying degree of the moisture content of the dried fruits is insufficient or excessive, and rework is required again, which delays a large amount of manpower and material resources. Moreover, during the drying process of the dried fruits, the fruits to be dried are directly placed on the drying plate after being sliced. During the drying process of the placed fruit slices, the side facing the radiant heat of the drying equipment is more obviously dried, and the drying effect on the other side is relatively poor. The drying process may cause different drying speeds and effects on both sides of the dried slices, affecting the consistency of the dried products. For this reason, we propose a dried fruit dryer capable of detecting moisture content. Content of the Utility Model

[0003] The utility model provides a dried fruit dryer capable of detecting moisture content, which solves the problems raised in the above background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A dried fruit dryer capable of detecting moisture content includes an oven box body. Inside the oven box body, there is a receiving mesh tray for holding dried fruits. Inside the oven box body, there are multiple layers of mounting racks fixedly installed. The receiving mesh tray is detachably installed on the mounting racks, and the receiving mesh tray can rotate on the mounting racks. At the same time, the top of the mounting rack gradually slopes downward from the outside to the inside. A positioning ring that can rotate relative to the receiving mesh tray is movably sleeved on the top of the receiving mesh tray. At the bottom end inside the positioning ring, there is a shoveling plate fixedly connected adjacent to the top of the receiving mesh tray. The shoveling plate is inclined. At the bottom of the oven box body, there is a hot air blower connected to the inside of the oven box body, and an air outlet pipe is installed at the top of the oven box body. And at the top of the oven box body, there is a humidity detector for detecting the water vapor in the air outlet pipe.
