Problems solved by technology

[0004] If the suction pipe is directly inserted into the packaging bag to pump water, the packaging bag at the suction port is easy to be pumped and blocked by materials, which will affect the pumping speed; and when the suction pipe is pulled out and resealed, it is easy to cause air to infiltrate into the packaging bag and easily cause secondary pollution

Embodiment 1

[0045] A vacuum packaging method for fast pumping and secondary sealing, such as figure 1 The shown packaging bag with a suction nozzle includes a main body 1 of the packaging bag, a filter belt 2 and a vacuum conduit 3 . The filter belt 2 is in the shape of a porous columnar strip, and its thickness is about 0.5 cm. Such as figure 2 , the filter belt 2 is set in the main body of the packaging bag 1, the surface of the filter belt 2 and the front and back sides of the main body of the packaging bag 1 are bonded together by heat and pressure respectively to form a tightly bonded, water-tight first adhesive belt 21 And the second adhesive tape 22, so that the packaging bag body 1 is divided into a relatively independent storage chamber 11 and a buffer chamber 12, and the gas-liquid communication between the storage chamber 11 and the buffer chamber 12 can only be realized through the filter belt 2. The packaging bag body 1 is a high-plasticity food-grade plastic bag, which is...

Embodiment 2

[0049] Such as Figure 4 As shown, the packaging bag used in this embodiment differs from that of Embodiment 1 in that: the discharge port 13 is arranged at the bottom of the buffer cavity 12, and the vacuum conduit 3 is arranged below the bottom of the packaging bag body 1. The structure of the vacuum conduit 3 is consistent with that of Embodiment 1, including a flexible conduit section 31 and a connecting pipe section 33; one end of the flexible conduit section 31 is connected to the discharge port 13, and the other end of the flexible conduit section 31 is connected to the connecting pipe section 33, and a one-way valve 32 is provided between the soft conduit section 31 and the connecting pipe section 33 to ensure that the liquid or gas flows in one direction from the flexible conduit section 31 to the connecting pipe section 33. The difference is that one end of the flexible conduit segment 31 in this embodiment is connected to the discharge port 13 and extends into the b...

Embodiment 3

[0051] In this embodiment, the packaging bag of Embodiment 1 or 2 is used to pack the chilled poultry and carry out ultra-high pressure sterilization treatment, so as to prolong the fresh-keeping time and fresh-keeping quality of the chilled poultry. The specific operation method includes the following steps:

[0052] Step 1: Using the packaging bag with the suction nozzle described in Embodiment 1 or 2, first discharge the air in the buffer chamber 12; put the pretreated fresh poultry carcass into the storage chamber 11 from the feed port 14 , and inject the bacteriostat aqueous solution containing nisin into the storage cavity 11; the added quality of the bacteriostatic aqueous solution must be no less than 20% of the mass of the poultry carcass, and the bacteriostatic aqueous solution must completely submerge the poultry carcass; After extruding to discharge the air in the packaging bag body 1, seal the feed port 14;

[0053] Step 2: Put the packaging bag containing the po...

Abstract

The invention provides a packaging bag with a drainage and exhaust pipe nozzle and a using method of the packaging bag. The packaging bag comprises a packaging bag body, a filtering strip and a vacuumizing guide pipe; the packaging bag body is provided with a feeding port and an unloading port, the filtering strip is arranged inside the packaging bag body, and the packaging bag body is at least internally provided with a storage cavity; the unloading port is formed nearby the filtering strip, and the storage cavity and the unloading port conduct gas-liquid breakover through the filtering strip; one end of the vacuumizing guide pipe is connected to the unloading port, and the other end of the vacuumizing guide pipe is provided with a pre-closed connection port; at least the section, connected to the unloading port, of the vacuumizing guide pipe is made of flexible rubber. When the packaging bag is adopted for ultrahigh-pressure food processing, the vacuumizing guide pipe can be connected with a vacuumizing device to quickly drain and exhaust water and steam in the packaging bag, and then the vacuumizing guide pipe can be closed and cut off to finish processing. By conducting packaging once, multiple processing procedures can be conducted, repeated packaging and repeated sterilization are omitted, secondary pollution is avoided, the time and materials are saved, and the processing cost is low.

Description

technical field [0001] The invention relates to the technical fields of food packaging and food processing, in particular to a packaging bag with a water suction nozzle, the application scope of the packaging bag, and a method for using the packaging bag in ultra-high pressure food processing. Background technique [0002] Existing food packaging bags generally reserve a material inlet and at most an air suction port. When vacuum packaging food, the processed food is generally drained of excess seasoning and sauce, and then put into the bag from the inlet, and the inlet is sealed while the bag is vacuumed, so that a vacuum seal is formed in the bag. status. [0003] Ultra-high pressure technology is a new type of non-thermal sterilization technology, which has been widely used in the food field. In order to effectively sterilize food materials, the processing pressure must reach 200-500MPa, which is generally suitable for liquid food materials, or solid food materials with...
