Large and automatic microwave and hot air combined rose flower drying production line and method

Abstract

The invention relates to the field of rose flower drying, in particular to a microwave and hot air combined rose flower drying production line and method. According to the microwave and hot air combined rose flower drying production line, a microwave heating chamber is arranged on the upper portion of a hot air chamber, a condenser is arranged at the position of a hot air outlet, and the microwaveheating chamber and the hot air chamber are isolated through a microwave leaking prevention plate. By means of the microwave and hot air combined rose flower drying production line, rose flower blocking and carbonized fires in the drying process can be prevented, and the safety performance and the drying efficiency of microwave layers are improved.

Description

technical field [0001] The invention relates to the field of drying flowers such as roses, which can stably obtain high-quality dried flowers and aromatic water, and particularly relates to a microwave and hot air combined large-scale automatic production line and method for drying roses. Background technique [0002] Conventional rose drying has been greatly improved from the traditional drying, shade drying, drying, initial drying room, hot air tunnel, to the application of new microwave, vacuum, and freeze drying equipment, but these rose drying processes exist. Different defects: hot air laminar drying due to low heat and mass transfer efficiency, the general drying time is more than ten hours, poor moisture removal leads to browning of petals and black stamens; microwave drying due to pulse work and magnetron overheating protection Due to the characteristics of intermittent operation, the harmonic current is large, the purchase cost and consumable cost are high, the dry...

[0002] Conventional rose drying has been greatly improved from the traditional drying, shade drying, drying, initial drying room, hot air tunnel, to the application of new microwave, vacuum, and freeze drying equipment, but these rose drying processes exist. Different defects: hot air laminar drying due to low heat and mass transfer efficiency, the general drying time is more than ten hours, poor moisture removal leads to browning of petals and black stamens; microwave drying due to pulse work and magnetron overheating protection Due to the characteristics of intermittent operation, the harmonic current is large, the purchase cost and consumable cost are high, the drying end point is difficult to control, and the risk of agglomeration, carbonization and even fire in the later stage of drying is high; the investment and operation cost of freeze-drying is high, similar to vacuum drying, which cannot Continuous production is realized, and the poor thermal conductivity of low-moisture materials in the later stage limits the thickness of the material, and the drying end is difficult to grasp

However, in this method, the de-enzyming and hot-air drying stages still take a long time, and due to the small dehydration amount of microwave de-enzyming, there are still defects in the later stage, such as sticky blocks and large damage to dried flowers.
