Abstract

The invention relates to the storage of flowers. The purpose of the invention is to increase the shelf life of flowers under reduced pressure. The color storage package contains a waterproof package 1 with a hermetically closed neck 2 and a bottom 3. In package 1, a frame 4 is installed (for example, a wire box) with flowers 5. The package is provided with inlet and outlet valves that allow to maintain equal pressures inside package 1 and repository. Through the package 1 passes the duct 6, having a per oration at the end immersed in water. When fresh air enters the storage, the inlet valve installed in duct 6 opens, and the air, humidified, passes through a layer of water and enters package 1. 3 sludge. .P ig.1

Description

one

The invention relates to the storage of flower slice.

The purpose of the invention is to increase the shelf life of flowers under reduced pressure.

Figure 1 shows a packaging for storing flowers; figure 2 - option 1. packaging, in which the duct, intake and exhaust valves are located in the neck of the package; FIG. 3 shows inlet and exhaust valves (exemplary embodiment).

The color storage package contains a waterproof package 1 partially filled with water, with a hermetically sealed neck 2 and base 3. Package 1 has a rigid frame 4 (for example, a search for flowers) with colors 5. The package is equipped with Air duct 6 with inlet valve 7, while the top the end of the air duct 6 protrudes above the outer surface of the package 1, and the lower end of the isog. chickpeas are placed along the base 3 of the package 1 below the water level and have perforations 8. On the package 1 an exhaust valve 9 is installed. Valves 7 and 9 can be placed in one block 10 and have channels 11 for the passage of air.

Color storage packaging works in the following way.

In the waterproof package 1 with water, a rigid frame 4 (box) with cut flowers 5 is installed, which are submerged in the roots. The neck 2 of the bag 1 is sealed. The package is installed (stacked) in a reduced pressure storage. In the latter, air pressure is generated. At the same time, when the pressure in the storage facility decreases, the exhaust valve 9 opens, and under the action of the pressure difference in package 1 and the medium in storage, air is removed from package 1. The pressure drop in the latter follows the pressure change in the storage. When the preset pressure level in the storage facility is reached, the automatic system for maintaining the necessary parameters of the storage process turns off the vacuum pumps (the working principle of the hypobaric storage facility here is considered only in relation to the proposed packaging). Then in the storehouse there is a STANDING of fresh

.air. The pressure in it rises. The exhaust valve 9 closes. The inlet valve 7 is opened. The pressure in the bag 1 is increased and equalized with the pressure of the medium in the storage. The air in the package 1 passes through the inlet valve 7, the air duct 6 and through the perforation 8 of the lower part. “The latter, bubbling through a layer of liquid, enters the internal volume of the package 1 ,. The air in the storage volume has a low relative humidity. Passing through the zodia layer, it is moistened. When a certain predetermined pressure is reached in the storage volume during air leaks, the system automatically starts a vacuum pump. In the storage volume, the pressure decreases again. In the package, the inlet valve 7 is closed and the exhaust 9 opens, etc. When storing floral products, the process of reducing and reducing pressure is carried out continuously.

The rigid frame 4, when the pressure changes, protects the flowers from the mechanical action of the walls of the waterproof package 1.

A step change in pressure in the internal storage volume occurs after loading and before unloading the product. Periodic pressure changes in the storage take place at

35 over the entire shelf life of the product due to the flow of fresh air into the internal storage volume. At the same time, the automatic.

40 storage modes (vacuum) turn on the vacuum pump when the pressure changes by 1300 - 2600 Pa, and the ventilation ratio of the storage can reach up to two volumes per hour.

45 Thus, in the proposed packaging for storing flowers, the supply of fresh air, ventilation of the flowers with fresh air while maintaining the relative humidity of the air at the desired

Level 50 allows et.e. to increase the shelf life of flowers and preserve their properties under reduced pressure of the medium.

The advantages of the invention are as follows. Firstly, it is possible to store flowers under reduced pressure when the relative humidity of the surrounding air. very low, while maintaining high quality products. Second, the age of 30

the ability to maintain a high relative humidity in the packaging, which eliminates product ingestion. Thirdly, the ability to ventilate products with fresh air, which is necessary to maintain the vitality of cut flowers.
