(4) Laser coding: and carrying out laser coding operation in the conveying process of the flower and plant tea cans conveyed by the nitrogen-filled can sealing machine.
(5) Turning over the bottle: and (5) turning the coded can by adopting a bottle turning machine, and then adding a plastic sealing cover to obtain a finished product.
The test is carried out by using chrysanthemum tea, and the residual oxygen content before and after nitrogen filling and the sensory evaluation results of tea are as follows:
example 4
The difference from the embodiment 1, 2 and 3 is that the invention can be used for various traditional teas such as white tea, yellow tea, green tea, loose dark tea and the like, can also be used for various raw materials such as flowers, leaves, rhizomes, seeds and the like of flower and grass tea and other similar-shaped foods or agricultural products, and only needs to customize weighing hoppers with different specifications according to the shapes of different materials.
Example 5
Compared with the embodiments 1, 2, 3 and 4, the difference is that the sealing aluminum foil of the tinplate can is improved, the edge of the aluminum foil inner cover is provided with a tearing ear part 4 which is used for opening the aluminum foil inner cover, the position of the aluminum foil inner cover, which is staggered with the tearing ear part, is also provided with a containing cavity 5, and the containing cavity 5 is internally provided with the healthy beans 6.
The design of adding grooves in the aluminum foil of the inner cover is adopted; the groove is designed to be capable of placing healthy beans; the design is specially used for secondary utilization of the packaging can, namely, the aluminum foil with tearing lugs at the bottom of the can is removed after the can is empty, and a proper amount of soil is placed in the can to plant healthy beans, so that the ecological value of the can is realized.
It should be understood that the above-mentioned embodiments are only examples for clearly illustrating the present invention, and are not to be construed as limiting the implementation. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Nor is it intended to be exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
