System and method for fresh-keeping cut flowers

Abstract

The present invention relates to a fresh-keeping treatment system and method for cut flowers. The fresh-keeping treatment method for cut flowers includes the steps of pretreatment with pretreatment liquid, grading, packaging and packing, and pre-cooling under pressure difference. The fresh-keeping treatment system for cut flowers includes unloading, pretreatment, A room temperature module for grading and packaging and a low temperature module for pre-cooling and storage of cut flowers. The normal temperature module includes unloading area, preconditioning liquid pretreatment area, and graded packaging area; the low temperature module includes pressure differential pre-cooling and storage. Through the matching use of the cut flower preservation treatment system and method, the division of normal temperature and low temperature regions and matching treatment methods is realized. Unloading, pretreatment, grading, packaging and packing are carried out sequentially under the normal temperature module, which avoids the adverse effects of temperature fluctuations in the processing process on the quality of cut flowers; pre-cooling and storage in the low temperature module shorten the The time required for pre-cooling improves the utilization rate of the pre-cooling storage and reduces the area of ​​the cooling area required by the entire cut flower preservation processing system.

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
