Cut flower fresh-keeping treatment system and method

Abstract

The invention relates to a cut flower fresh-keeping treatment system and method. The cut flower fresh-keeping treatment method comprises the steps of pre-treatment liquid pre-treatment, grading, packaging and boxing, differential pressure pre-cooling and the like. The cut flower fresh-keeping treatment system comprises a normal-temperature module used for cut flower unloading, pre-treatment, grading and packaging and a low-temperature module used for cut flower pre-cooling and storage, wherein the normal temperature module comprises an unloading area, a pre-treatment liquid pretreatment area and a graded packaging area; and the low-temperature module comprises a differential pressure pre-cooling storage and a storage. Through matched use of the cut flower fresh-keeping treatment system and method, division of normal-temperature and low-temperature areas and matched treatment methods is realized. The operations of flower unloading, pretreatment, grading, packaging and boxing and the like are sequentially carried out under the normal-temperature module, so that the adverse effect of temperature fluctuation in the treatment process on the quality of cut flowers is avoided; and differential pressure pre-cooling and storage are carried out in the low-temperature module, so that the time required by pre-cooling is shortened, the utilization rate of the pre-cooling storage is improved, and the area of a refrigeration area required by the whole cut flower fresh-keeping treatment system is reduced.

Description

technical field [0001] The invention relates to the technical field of cut flower preservation, in particular to a cut flower preservation treatment system and method. Background technique [0002] Rose is an important flower crop in the world, and its output and consumption both rank first among cut flowers. More than half of my country's rose production is in Yunnan, and the consumer market is mainly in the central coastal cities and large and medium-sized cities in the north. The production and sales areas are separated, and the average transportation radius required is more than 1500 km. Due to the lack of a standardized post-harvest fresh-keeping process for cut roses, the cut roses cannot be properly and properly post-harvested after harvesting, resulting in rapid quality deterioration of cut roses during and after long-distance transportation. Then affect the ornamental value and reduce the economic value of rose cut flowers. [0003] After the cut flowers are harve...

AI Technical Summary

Problems solved by technology

Such a treatment process will bring the following problems: (1) The temperature fluctuations in different processing links will adversely affect the quality of cut flowers; (2) Pretreatment of the pretreatment solution in a low temperature environment will result in slow absorption of the pretreatment solution, thereby prolonging the treatment time , resulting in low processing efficiency and high energy consumption; (3) The pre-cooling method of cut flowers usually uses cold storage air pre-cooling, and the pre-cooling rate of cut flowers is slow; (4) It is not suitable for operators to work for a long time in the cold storage. The area used for packing needs to be included, which will expand the required cooling area and increase energy consumption; (5) The operations in each area are mainly manpower, and the level of mechanization is low, which is not conducive to the high efficiency and standardization of post-harvest treatment

The airflow in the square cold storage has a dead angle when it circulates. Due to the long-term slow gas exchange speed, the local temperature will form a large temperature difference with other parts during the real-time temperature change process. When the airflow in the storage changes, the The temperature in some areas will affect the temperature uniformity in the entire library, and may accumulate oxygen and other substances that promote plant respiration in local areas. When this part of the gas comes into contact with cut flowers, it will promote the respiration rate of the cut flowers in contact with it. Affect the pre-cooling effect of cut flowers, reduce the detection value of the detection device in the cold storage and affect the response sensitivity of the control system, affect the control of temperature and gas concentration in the cold storage, so that the actual pre-cooling effect of cut flowers and the ideal pre-cooling effect are produced There are large differences, and even cause problems such as cold storage imbalance and cut flower damage

However, because the airflow in the storage body changes from time to time, the local temperature is not easy to sense, so such problems cannot be avoided
