Abstract
An aseptic tank capable of isolating liquid from air. The device is characterized in that two stainless steel seal heads with the same radian are used, one is used as a lower seal head of the sterile tank body, and the other is used as a lower end head of the piston, so that after the piston reaches a lower dead point, the piston and the lower end of the sterile tank body are in close joint without leaving a gap. At this time, the space above the upper end enclosure and the piston in the sterile tank is occupied by the filtered sterile air. When the aseptic liquid is injected from the inlet and outlet at the lower end of the aseptic tank, the liquid jacks up the piston, and air above the piston is exhausted from the air inlet and outlet at the upper part of the aseptic tank. When the aseptic liquid is pumped out from the inlet and outlet at the lower end of the aseptic tank, the piston and the aseptic liquid synchronously descend, and meanwhile, the air inlet and outlet at the upper part of the aseptic tank sucks aseptic air. The sterilized aseptic liquid is not contacted with air and other objects all the time. Especially, the liquid which can not contain gas after being degassed and can not contact with the air after being degassed is added with specific gas, so that the effects of buffering, storing, regulating and isolating the air are really achieved.
Description
Technical Field
The present invention relates to an aseptic tank with a piston to isolate the liquid from the air. In the production process of food, beverage, dairy product and medicine industries, after sterilization and before filling, the sterile liquid is buffered by isolating air and stored in a sterile tank body, thereby playing a role in regulating and controlling the production process. The liquid isolates air and prolongs the shelf life.
Background
At present, no sterile tank capable of isolating liquid from air exists in China. Only the introduced tetra-n aseptic cans. The principle is that; the sterilized liquid enters from an inlet and an outlet at the lower end of the tetra pak aseptic tank through a booster pump. The liquid enters the space to be occupied in the tank, namely the air in the tank is exhausted from the air inlet and outlet at the upper end of the tank. When filling or carrying out the next procedure, the liquid is pumped out from the inlet and the outlet at the lower end of the tetra pak aseptic tank by a pump. At this time, the space vacated by the liquid pumped by the pump in the tetra pak aseptic tank is sucked by the air inlet and outlet at the upper end of the tank body after passing through the filtration, so that the sterilized liquid always has oxygen, and the chance of revival survival is created for the residual germs in the liquid. In particular, it is not useful for liquid products which require no further contact with air after degassing or which require the addition of a specific gas after degassing. The liquid in the tetra pak aseptic tank is mixed with air although the liquid can kill germs.
Disclosure of Invention
In order to overcome the disadvantages of the tetra pak aseptic tank that it is not possible to isolate the sterilized liquid from air and that it is not necessary to have access to air after degassing or to add a specific gas to the liquid after degassing. The invention provides a sterile tank. The aseptic tank can regulate and control the liquid in the processes of caching, storing and filling the sterilized liquid or in the next process. And does not contact air. In particular, the liquid which is not required to contact with the air after being degassed or added with the specific gas after being degassed does not contact with the air any more, and the quality and the characteristic of the liquid are kept stable and unchanged.
The technical scheme adopted by the invention for solving the technical problem is as follows; according to the principle of an internal combustion engine, a cylinder barrel, a piston and a combustion chamber, the combustion chamber is used as an aseptic tank, sterilized aseptic liquid enters the combustion chamber, the piston is jacked up, the aseptic liquid is extracted, and the piston falls down along with the liquid level of the aseptic liquid. The sterile liquid in the combustion chamber is not contacted with air and other irrelevant components all the time, so that the aim of non-contacting air sterilization is achieved. The sterilization material inlet pipe with the valve, the sterile air inlet pipe with the valve, the sterile tank upper end enclosure, the upper end enclosure and tank body connecting bolt, the sterile tank body, the sterile tank lower end enclosure, the sterile tank supporting legs and the sterile liquid inlet pipe are sequentially connected from top to bottom, a piston which is provided with an upper piston ring and a lower piston ring and can be tightly worn with the sterile tank body, the lower end face of the piston has the same radian with the lower end enclosure and can be highly overlapped without leaving a gap is arranged in the tank body. The sterile liquid inlet and outlet pipe is characterized by comprising a sterile material inlet pipe with a valve, a sterile air inlet and outlet pipe with a valve, and a sterile liquid inlet pipe and a sterile liquid outlet pipe with a valve, wherein the sterile material inlet pipe and the sterile air inlet and outlet pipe are respectively and vertically welded on two sides of an upper end socket of a sterile tank, the upper end socket of the sterile tank is connected with a tank body of the sterile tank through an upper end socket and a tank body connecting bolt, the tank body of the sterile tank is connected with a lower end socket of the sterile tank in a welding way, a support leg of the sterile tank is welded on the lower end socket of the sterile tank, one end of a sterile liquid inlet and outlet pipe is welded in the. Sterile liquid is pumped into the sterile liquid inlet and outlet pipe through a sterile liquid inlet pipe with a valve by a pump, and when the pressure in the sterile liquid inlet and outlet pipe is greater than the friction force generated by the piston dead weight plus the piston and the sterile tank body, the piston is jacked by the sterile liquid and is buffered in a space formed by the lower end surface of the piston and the lower end socket of the sterile tank. The pressure in the inlet and outlet pipes of the sterile liquid controls the piston to float up and down, so that the sterile liquid does not contact air and other equipment parts to achieve the aim of sterility.
The invention has the beneficial effect that the sterile tank can isolate air in the production process of the sterile liquid, thereby greatly reducing the chance of reviving and surviving of residual germs in the sterile liquid. Especially, the research and development and application of a new product which is required to be degassed and then not contacted with air and added with specific gas play a key role for liquid products.

Detailed Description
Two stainless steel end sockets with the same radian, one is a lower end socket 18 of the sterile tank, and the other is a lower end surface 17 of the piston, so that after the piston reaches a lower dead point, the lower end surface 17 of the piston and the lower end socket 18 of the sterile tank are in close contact without leaving a gap. The sterile liquid inlet and outlet pipe 14 is left in the middle of the lower end socket 18 of the sterile tank, and when the sterile liquid is pumped from the sterile liquid inlet pipe 19 by a pump, the sterile liquid enters the piston lower end surface 17 of the outlet pipe 14 through the valve 15 to jack the piston. When the aseptic liquid is pumped out from the aseptic liquid outlet pipe 20 by the pump, the lower end surface 17 of the piston and the liquid level of the aseptic liquid synchronously descend until the lower end surface 17 of the piston and the lower end cover 18 of the aseptic tank are completely superposed and the aseptic liquid is completely pumped out.
The invention works in two modes; "1" for storage of sterile liquid, the piston is raised by closing the valve 16 from the inlet tube 19 of sterile liquid through the inlet and outlet tubes 14 of sterile liquid by the pump 15 and stored in the space formed by the lower end surface 17 of the piston and the lower end closure 18 of the sterile tank. When the aseptic liquid is stored and regulated, and filled or processed in the next procedure, the aseptic liquid is pumped from an aseptic liquid inlet pipe 19 to an aseptic filling machine or processed in the next procedure through a valve 15, a valve 16 and an aseptic liquid outlet pipe 20. When the sterile filling machine or the next procedure is in failure and causes local shutdown, the pressure of the sterile liquid in the sterile liquid inlet and outlet pipe 14 is increased when the sterile liquid loses the outlet path, and when the pressure is larger than the dead weight and the friction force of the piston, the piston is slowly jacked up by the sterile liquid and is slowly stored in the sterile tank. When the sterile filling machine or the next procedure recovers to work normally, the piston body floats up and down according to the pressure of the sterile liquid inlet and outlet pipe 14, and the buffer and regulation functions are achieved. In both modes, the air inside the sterile canister is regulated by the valves 3 with the piston up and down and sterile air in and out tubes 4. The air is sterile air after multi-stage filtration, is isolated by a piston and is not contacted with the sterile liquid all the time. After a batch of work is finished, the aseptic tank needs to be cleaned, sterilized and disinfected. The CIP sterilization cleaning system is characterized in that a piston is jacked up by a sterile liquid inlet 19 through a valve 15 and a sterile liquid inlet and outlet pipe 14 for cleaning and sterilization, and a space is formed by a lower end surface 17 of the piston and a lower end socket 18 of a sterile tank. The space formed by the upper seal head 5 and the piston of the aseptic tank is sterilized from the high-temperature dry steam, or ozone, chlorine dioxide, the valve 2 sterilizing material inlet pipe 1 to the aseptic tank body 21. When in maintenance, the upper end enclosure and the tank body connecting bolt 6 are dismantled, the upper end enclosure 5 of the sterile tank is removed, the exhaust valve 10 and the exhaust valve 11 are opened, and the piston can be lifted out through the piston lifting hook 9.
