Essential oil applying device used for modified atmosphere packaging on the basis of plasma sterilization

Abstract

The invention discloses an essential oil applying device used for modified atmosphere packaging on the basis of plasma sterilization, and relates to the technical field of food processing. The essential oil applying device comprises a transportation frame, wherein the transportation frame is provided with a conveying channel; in the conveying channel, a plurality of transmission parts are installed at equal intervals; a plurality of sieve pores are arranged between two adjacent transmission parts; a conveying part fixed on the transportation frame is installed below the sieve pores; in the transportation frame, installation grooves which communicate with the sieve pores are arranged; and a coating part is rotatably installed in each installation groove. Two oppositely installed coating parts rotate to the direction of the sieve pores, when Castanea mollissima BL. moves between the two coating parts, the Castanea mollissima BL. extrudes the supporting plates of the coating parts, the supporting plates which are bent to the inner side push pushing plates to extend into air cylinders, gas mixed with essential oil in the air cylinders flows into deep grooves through air discharging channels to cover the surface of the Castanea mollissima BL., so that an anti-bacteria effect is realized, and Castanea mollissima BL. preservation time is prolonged.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to an essential oil applicator for modified atmosphere packaging based on plasma sterilization. Background technique [0002] Chestnuts are susceptible to infection by harmful microorganisms such as bacteria and molds, resulting in rot and deterioration during storage and transportation after picking. Therefore, effectively inhibiting the infection and reproduction of pathogenic microorganisms on the surface of chestnuts and in the storage environment is important to maintain the fresh quality of fruits and vegetables. An effective means of storage time. The key to fresh-keeping storage is to adjust the temperature, humidity and gas composition of fresh-keeping. The fresh-keeping methods in the prior art generally put fruits and vegetables directly into the cold storage for cold storage, resulting in the loss of water in the fruits and vegetables. Propagation makes fruits an...

[0002] Chestnuts are susceptible to infection by harmful microorganisms such as bacteria and molds, resulting in rot and deterioration during storage and transportation after picking. Therefore, effectively inhibiting the infection and reproduction of pathogenic microorganisms on the surface of chestnuts and in the storage environment is important to maintain the fresh quality of fruits and vegetables. An effective means of storage time. The key to fresh-keeping storage is to adjust the temperature, humidity and gas composition of fresh-keeping. The fresh-keeping methods in the prior art generally put fruits and vegetables directly into the cold storage for cold storage, resulting in the loss of water in the fruits and vegetables. Propagation makes fruits and vegetables stale and even rotten, resulting in unnecessary losses and waste of fruits and vegetables

Or use plasma sterilization for sterilization treatment. At the same time, after plasma sterilization treatment, it is easy to be contaminated with other bacteria during transportation, which is not convenient for long-term storage of chestnuts.

The existing fresh-keeping methods and sterilization methods for chestnuts are relatively single, only using ozone sterilization, ultraviolet sterilization or plasma, the sterilization effect is not very good, and after the modified atmosphere packaging, the surface of the modified atmosphere packaging box is prone to fogging, and the modified atmosphere The box itself does not have antibacterial effect
