Description

Filling method for liquid with particles

Technical Field

The invention relates to a liquid filling method and equipment for the method, in particular to a filling method of liquid with particles, equipment for the method and a packaging box.

Background

Most of the filling technologies adopted by the existing packaging boxes are under-liquid sealing, namely the beverage filling amount of the existing aseptic carton filling machine is basically consistent with the volume of the packaging box, no redundant space exists in the packaging box, and more articles cannot be added by adopting any method. In order to meet the needs of consumers, particulate matters such as fruit grains and coarse cereals need to be added into the beverage, as shown in fig. 1, if a filling method in the prior art is used for filling granular liquid, the particulate matters need to be added into the liquid, when the filled packaging box is sealed and formed, the particulate matters can be randomly suspended in the liquid, so that the particulate matters can be easily generated at the sealing position, or after the filling is completed, the situation that the particulate matters are retained in the sealing area can exist, so that the packaging box is poorly sealed, air permeability and bacteria permeability are caused, the filled liquid leaks and rapidly deteriorates, the expected quality guarantee period can not be reached, even sealing can not be formed, and the product can not be sold.

Disclosure of Invention

The invention aims to provide a filling method, filling equipment and a packing box for liquid with particles, which can realize filling of the liquid with particles.

In order to solve the above problems, a first aspect of the present invention provides a method for filling a liquid with particles, comprising the steps of: a gas injection step, injecting a proper amount of gas into the liquid, thereby forming a pourable gas-liquid mixture; a liquid filling step, namely filling the gas-liquid mixture into a packaging box to complete sealing, and standing for a while to separate out and separate gas from the gas-liquid mixture; and a secondary filling and sealing step, namely opening the filled packaging box, injecting particles, and sealing the packaging box again.

Injecting a proper amount of gas into the liquid to form a gas-liquid mixture, filling the liquid fully during filling, standing for a moment after filling is completed, separating out and separating the gas from the liquid, enabling the gas space formed in the packaging box to contain particles, opening the packaging box, injecting the particles, and sealing the packaging box again.

Further, in the gas injection step of the filling method for liquid with particles, the gas is injected into the liquid in the form of small bubbles.

Further, the gas injection amount in the above-mentioned filling method of liquid with particles can be adjusted according to the ratio of the particles to be filled to the volume of the package box.

Further, in the filling method of the liquid with the particles, the gas in the gas injection step is 27-33 ℃, the temperature is consistent with the temperature of the filling materials, and the filling materials are not easy to change.

Further, in the filling method of the liquid with particles, the gas in the gas injection step is nitrogen or air.

Nitrogen or air is very suitable for being injected into liquid because it is relatively stable, easily available, and harmless to human body and environment.

Further, in the step of injecting gas in the filling method of liquid with particles, the gas is firstly sterilized and then injected into the liquid.

Further, the liquid filling step in the above liquid filling method with particles further includes: and a packaging box cutting step, namely cutting the sealed part of the packaging box which is filled according to the requirements of size and the like, so that the packaging box which is filled is separated from the packaging box to be filled.

Further, in the above-mentioned liquid filling method with granules, in the secondary sealing step, the top area of the package is opened.

Further, in the secondary sealing step in the liquid filling method with particles, the top area is a suction pipe opening, an opening or a cover attaching opening of the packaging box.

According to another aspect of the invention, a filling device for liquid with particles is also provided, which is used for implementing any one of the filling methods for liquid with particles.

According to another aspect of the invention, there is also provided a package produced by any one of the above-described liquid filling methods with granules.

The invention injects proper amount of gas into liquid to form gas-liquid mixture, and fully fills the liquid when filling, after filling, the gas is separated from the liquid, the gas space formed in the packing box can contain particles, after opening the packing box, the particles can be injected, and secondary sealing is completed, thereby realizing filling of the liquid with particles.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The embodiment of the invention shows a filling method of liquid with particles, any two substances in liquid or gaseous form can be mixed to a certain degree, so that gas is continuously and uniformly injected into the liquid to form a gas-liquid mixture, the amount of the injected gas is adjusted according to the ratio of filled particles to the volume of a packaging box, in order to better mix the gas with the liquid, the gas is preferably injected in the form of small bubbles, the temperature of the gas is kept constant within the range of 27-33 ℃, the temperature is preferably stabilized at 30 ℃, and the temperature is consistent with the temperature of the filling material, so the filling material is not easy to change. Since nitrogen is very easily available and harmless to the human body and the environment, nitrogen is generally used as the gas to be injected into the liquid, and it is of course possible to inject air. In order to ensure the hygiene of the product, the gas is sterilized before the liquid is injected, and the liquid is injected after the gas is sterilized.

Referring to fig. 2, the liquid in the package is filled into the package and sealed, and after the package is placed still for a while, referring to fig. 3, gas is automatically separated from the gas-liquid mixture, so that a gas space is formed at the top of the package for containing the filled particles.

Referring next to fig. 4, the package box that has been left standing and gas separated from the liquid is opened with an opening, which may be a straw opening, an opening or a cover opening of the package box, and particles, which are usually fruit particles, grains and other additives, are injected from the opening, and the package box uses the following packaging materials in sequence from outside to inside: PE layer, bond line, ply, PE layer, bond line, aluminium foil layer, bond line, PE layer and PE modified layer, simultaneously for more convenient, the mouth of pipe is inhaled in this kind of packing carton production reservation, is opened mouthful or pastes the flap mouth, owing to do not have the ply, so be convenient for open, the secondary involution of also being convenient for moreover. After the injection of the particles is finished, the packaging box is sealed for the second time, so that the filling of the liquid with the particles is realized.

The second embodiment of the invention shows a filling device for liquid with particles, which is used for implementing the filling method for liquid with particles shown in the first embodiment.
