Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a low-oxygen drying equipment. Background Technology

[0002] During the production and processing of goji berries, low-oxygen drying equipment is typically used. A low-oxygen dryer is based on a traditional dryer but is made entirely sealed. When the goji berries are placed inside the dryer, the inlet is closed, then the vacuum pump is turned on to remove the internal air, and finally, an inert gas (nitrogen) is introduced. The inert properties of nitrogen prevent oxidation of the goji berries during the drying process.

[0003] When using existing low-oxygen drying equipment, the humidity in the drying environment for goji berries is too high, which slows down the evaporation of moisture from the surface of the goji berries and makes it difficult to remove the moisture generated during the drying process in time. This can easily cause the goji berries to darken in color. In addition, the single drying method can lead to localized high temperatures, resulting in uneven drying and affecting the drying effect and color. Utility Model Content

[0030] In this embodiment of the disclosure, such as Figure 2 As shown, the pre-cooling chamber 106 is equipped with six circulating fans 1061, which are arranged in a rectangular array. The pre-cooling chamber 106 has two connecting pipes 1062 at the rear, which are connected to the raw material chamber 102. The pre-cooling chamber 106 has a first connecting pipe 1063 at the front.

[0031] The water trap 3 has a second connecting pipe 301 at the rear and a communicating vessel 302 at the rear, which is connected to the second connecting pipe 301 and the first connecting pipe 1063.

A discharge pipe 305 is provided on one side of the defroster 303. Since the entire drying process is in a fully sealed state, in the circulation system, six circulating fans 1061 are set up to first cool down the high temperature and high humidity air, and then let the water vapor-containing gas pass through the water trap 3, which is divided into two low temperature water traps 3. When the left water trap 3 is working, the right defroster 303 defrosts, and when the right water trap 3 is working, the left defroster 303 defrosts.

By adjusting the position, the local temperature is avoided from being too high, and it is convenient to quickly push the heated goji berries to the cooling zone for cooling treatment.

[0036] The working principle of this embodiment is as follows: During use, the entire drying process is in a fully sealed state. The drying chamber 1 is evacuated by a vacuum pump. In the circulation system, six circulating fans 1061 are set up to first cool down the high temperature and high humidity gas. Then, the gas containing water vapor passes through the water trap 3, which is divided into two low temperature water traps 3.

This cycle alternates to achieve rapid dehumidification. After drying is completed, all heating systems are turned off, and the vacuum pump is turned on again to reduce the internal pressure, thereby allowing the goji berries to expand.
