Description

Technical Field

[0001] The invention belongs to the field of soft can packaging equipment, and in particular relates to an auxiliary packaging device and method for soft canned meat containing soup and with thorns. Background Art

[0002] The integrity of canned meat packaging is directly related to the quality and safety of the food inside. For some fish or meat products with small bones, the packaging and transportation process must prevent the tips of bones or thorns from directly facing the outer surface of the bag. On the one hand, for relatively soft fish bones or meat with small bones, the length of the bone or the main fish bone should be aligned with the length or width of the bag, rather than the thickness of the bag. This ensures the appearance of the filled meat remains intact and aesthetically pleasing, improving consumer shopping satisfaction. On the other hand, during transportation, more care and standardized procedures are required to prevent the canned meat packaging from being damaged by scratches and to prevent hard meat bones such as fish bones from penetrating the bag. This poses significant challenges to the transportation of canned meat, especially due to many uncontrollable factors such as accidental bumps or violent collisions. Therefore, maintaining the integrity of the packaging for these thorny canned meats presents a significant challenge for manufacturers.

[0003] To recreate the authentic flavor of the broth, some canned meat products often incorporate broth. Maintaining the integrity of the packaging for these spur-bearing meats, including broth, presents a practical challenge that needs to be explored and addressed. Many broth-based meats are stored at low temperatures after shipment to maintain quality and freshness, leaving the broth essentially in a gel state. However, during the production and processing stages, the broth may experience a fluid phase, which presents challenges in adjusting the position of the spur-bearing meat. While manual adjustment can address significant large spurs, this approach is inefficient and cannot fully address all spur locations, nor can it eliminate sharp points on the packaging surface that could cause stress concentration and bag breakage. With the increasing automation of food packaging lines, manual adjustment of spur-bearing positions is gradually becoming obsolete, driven by both production efficiency and food safety considerations.

[0004] Therefore, in order to adjust the position of the filled food in the soft can of thorny meat containing soup, a new auxiliary packaging device and method are developed on the basis of the existing packaging device to effectively solve the problem of the integrity of the surface of the soft can packaging bag, which is very important for the production and processing of soft cans of thorny meat food. Summary of the Invention

[0005] In response to the above problems existing in the prior art, the auxiliary packaging device and method for soft canned meat with thorns containing soup of the present invention starts from the packaging stage. Through the design of the auxiliary packaging device structure and the design of the auxiliary packaging method, the flexibility of the soft can packaging bag and the properties of the soup in the soft can are fully utilized. An intermittent impact method is adopted to squeeze the outer surface of the soft can packaging bag filled with thorny meat food, and the soup is used to realize the transmission of force and deformation, and to form an effective buffer for the filled food, thereby realizing local vibration and displacement of the filled thorny meat food, thereby eliminating the sharp points on the outer surface of the packaging bag, so that the packaging bag will not be punctured during the later packaging and transportation process.

[0006] The auxiliary packaging device for canned meat with thorns containing soup of the present invention adopts the following main technical solutions:

[0007] The auxiliary packaging device includes a U-shaped fluid sleeve, which includes a base compartment, a fluid compartment and a transfer compartment. The base compartment and the fluid compartment are sealed and isolated, and the transfer compartment is located at the bottom of the base compartment and the fluid compartment. A one-way pressure valve is provided between the fluid compartment and the transfer compartment for liquid to enter the transfer compartment from the fluid compartment. The fluid compartment is filled with liquid, and the outer surface of the fluid compartment constitutes a concave groove of the fluid sleeve. The groove can accommodate a soft can packaging bag, and the two side surfaces of the soft can packaging bag are in contact with the inner surface of the groove of the fluid sleeve respectively, while the bottom of the soft can does not contact the bottom of the groove of the fluid sleeve. The outer surface of the fluid compartment is elastic. A deformable membrane layer; the base warehouse is provided with a hollow linear conduit that passes through the base warehouse and enters the fluid warehouse, the inlet end of the hollow linear conduit is provided with a pressure device, and the outlet end of the hollow linear conduit is provided with a one-way valve cover for liquid to flow from the inside of the hollow linear conduit to the fluid warehouse. The pressure device pressurizes the liquid in the hollow linear conduit and sprays it from the outlet end to the inner surface of the fluid warehouse, so as to change the local shape of the inner surface of the fluid warehouse and the surface of the soft can packaging bag in real time, so that the thorny meat food in the packaging bag is impacted and changes its position; a liquid cavity is provided in the pressure device, and the liquid cavity is connected to the transfer warehouse by a pipeline.

[0008] The auxiliary packaging device for canned meat with thorns containing soup of the present invention also adopts the following auxiliary technical solutions:

[0009] High-density particles are also added to the liquid in the fluid compartment.

[0010] The hollow straight conduit is arranged obliquely upward, and the angle between the axis of the hollow straight conduit and the plumb line direction of the packaging bag does not exceed 45 degrees.

[0011] The auxiliary packaging device also includes an outer shape pre-sensing pressure device, the outer surface of which is provided with a force sensing surface, and the pre-sensing pressure device is used to sense the distribution position of the sharp points on the surface of the soft can packaging bag.

[0012] The positions of the hollow linear conduits are evenly distributed and the spraying range covers the entire inner surface of the fluid compartment. The pressure at the inlet end of any hollow linear conduit is individually controlled by a pressure device.

[0013] The outlet end of the hollow linear conduit does not contact the inner surface of the fluid chamber.

[0014] The auxiliary packaging device also includes an outer shape bracket.

[0015] The method for using the auxiliary packaging device for canned meat with thorns containing soup of the present invention comprises the following steps:

[0016] (1) Pre-judgment of the position of the sharp points on the surface of the soft can packaging bag: The soft can packaging bag is placed in a fluid sleeve, and the shape pre-sensing pressure device is used to sense the distribution of the sharp points on the surface of the soft can packaging bag in a natural plumb state; during the pre-judgment process of the position of the sharp points on the surface of the soft can packaging bag, the force sensing surface is completely in contact with the surface of the soft can packaging bag;

[0017] (2) Adjustment of the surface profile of the fluid sleeve: According to the distribution of the cusp positions obtained in the previous step, the pressure device at the corresponding position is started, and the corresponding hollow linear conduit is used to spray liquid to change the pressure at the cusp position, and then the position of the cusp is adjusted by extrusion deformation. In this process, the shape pre-sensing pressure device is used to sense the position changes of the cusp position on the packaging bag surface many times, and the surface profile of the fluid sleeve is adjusted in a targeted manner until there are no obvious cusps on the packaging bag surface;

[0018] (3) Adding an external shape bracket to the soft can packaging bag: The outer surface of the packaging bag obtained in the previous step is shaped using a mesh binding bracket for vacuum sealing in the next process; the high-pressure liquid is sprayed in an intermittent manner in the hollow linear conduit.

[0019] Compared with the prior art, the auxiliary packaging device and method for canned meat with thorns containing soup of the present invention have the following advantages:

[0020] First, based on the actual characteristics of soft-canned meat with thorns containing soup, the present invention adds the auxiliary packaging device of the present invention to the normal production process of the production line, completely replacing the new problems that may be caused by manual adjustment in terms of production efficiency and food safety. It can be implemented through a simple modification of the existing production line and effectively solves the adverse effects of bone spurs on the soft-canned food packaging bag. The present invention uses a deformable film layer on the surface of a flexible fluid sleeve to achieve on-demand adjustment of the position of the spur-like food in the soft-canned food packaging bag. This not only effectively protects the complete shape of the soft-canned meat food packaging bag, so that the meat food does not cause external damage during the entire position adjustment process, but also avoids the problem of bone spurs breaking off and falling into the soup or puncturing the packaging bag during the production or transportation stages, thereby improving consumer satisfaction.

[0021] Second, the present invention adopts a safer and more reliable flexible impact and flexible deformation adjustment design for the position adjustment of the thorny meat-filled food in the soft can packaging bag. The sharp points on the surface of the packaging bag are usually caused by the bone spurs of the meat food filled in the packaging bag. The stress concentration at the sharp points is very significant, thus generating a great risk of bone spur breakage or soft can packaging bag rupture. Therefore, the technical solution of the present invention adopts a safer and more reliable flexible impact and flexible deformation adjustment design in position adjustment. The deformation of the outer surface of the fluid sleeve is achieved by spraying high-pressure liquid from a hollow straight conduit with an oblique upward design, thereby generating deformation transmission to the soft can packaging bag in contact with it. Combined with the superposition of the downward gravity and the oblique upward liquid impact force, the meat food is turned over and shaken, and the presence of the soup in the packaging bag also plays a good buffering effect. The impact of high-pressure liquid is carried out intermittently, so that the thorny meat food will not be subjected to continuous pressure and cause the bone spurs to break. At the same time, the fluid properties of the soup and the gravity of the filled food are used to achieve adaptive adjustment of the position of the food in the packaging bag; the design of separate control of the pressure device is used to carry out targeted and gentle adjustment of the position of the thorny meat food, which can achieve the fixed-point elimination of the sharp points on the outer surface of the packaging bag; and the connection between the transfer bin and the fluid bin, as well as the design of the pressure device, achieves the continuity of the shape adjustment process of the soft can packaging bag.

[0022] Third, the present invention incorporates a pre-shaped pressure-sensing device and a pre-shaped support, further enhancing the effectiveness of the packaging process. The pre-shaped pressure-sensing device effectively detects the position of sharp points on the outer surface of the packaging bag, providing a reference for pressure control of the pressure device and opening of the hollow linear conduit, thereby improving the efficiency of position adjustment. The pre-shaped support ensures that the optimal position of the spiny meat product within the packaging bag is fixed and protected during subsequent processing, ensuring that the shape is fixed after the soup has cooled and solidified or vacuumed.

[0026] The present invention's auxiliary packaging device for canned meat products containing thorns and soup, as an auxiliary device for filling food bags in a canned food production line, does not disrupt the structure and production process of established canned food production lines. For these reasons, the structure and production process of established canned food production lines in the prior art will not be described, as those skilled in the art will readily understand the prior art. The following detailed description will focus solely on the technical solutions of the present invention.

[0027] See also Figure 1 and Figure 2 The auxiliary packaging device of the soft can of thorny meat containing soup of the present invention comprises a U-shaped fluid sleeve 1, the fluid sleeve 1 comprises a base bin 3, a fluid bin 2 and a transfer bin 5, the base bin 3 and the fluid bin 2 are sealed and isolated, the transfer bin 5 is located at the bottom of the base bin 3 and the fluid bin 2, and the transfer bin is pre-filled with some liquid, and a one-way pressure valve 51 is provided between the fluid bin 2 and the transfer bin 5 for liquid to enter the transfer bin 5 from the fluid bin 2, thereby realizing the circulation of liquid in different bin spaces; the fluid bins 2 are all filled with liquid, the outer surface of the fluid bin 2 constitutes a concave groove of the fluid sleeve 1, and the groove constitutes the U-shaped inner surface structure of the fluid sleeve 1; the groove can accommodate a soft can packaging bag, and the soft can packaging bag in the groove is in a natural plumb state, the two side surfaces of the soft can packaging bag are in contact with the inner surface of the groove respectively, and the bottom of the soft can does not contact the bottom of the groove of the fluid sleeve 1, thereby realizing that the filling food in the packaging bag can be in a natural state and the position can be effectively adjusted accordingly. The size and dimensions of the slot of the U-shaped fluid sleeve 1 are determined and designed according to the soft can packaging bag to be processed and the amount of food filled, so as to achieve effective contact between the two side surfaces of the soft can packaging bag and the inner surface of the slot.

[0028] The fluid chamber 2 is a thin-walled structure, and the surface of the fluid chamber 2 is an elastic deformable membrane layer 21, which also serves as the recessed grooved surface of the fluid sleeve 1. The thickness of the fluid chamber 2 does not exceed 10 mm. Preferably, the thickness of the fluid chamber is 3 mm, 5 mm, or 10 mm. The thickness of the fluid chamber is limited so that the deformable membrane layer 21 on the surface of the fluid chamber will not be significantly deformed under the action of liquid gravity in a static state. Furthermore, in order to prevent the concentrated squeezing of the bottom deformable membrane layer by the liquid pressure in the fluid chamber, resulting in excessive deformation differences between the bottom and upper positions, a mesh pressure strip is provided on the outer surface of the deformable membrane layer of the fluid chamber 2 to provide effective support for the deformable membrane layer and avoid excessive differences in the amount of liquid in the upper and lower parts of the fluid chamber 2.

[0029] The base bin 3 is provided with a hollow linear conduit 4 that passes through the base bin 3 and enters the fluid bin 2. The inlet end of the hollow linear conduit 4 is provided with a pressure device 41, and the outlet end of the hollow linear conduit is provided with a one-way valve cover (not shown in the figure) for liquid to flow from the inside of the hollow linear conduit to the fluid bin. The pressure device 41 pressurizes the liquid and sprays it from the outlet end of the hollow linear conduit 4 onto the deformable membrane layer 21 on the surface of the fluid bin 2, so as to change the local shape of the contact surface between the fluid bin 2 and the surface of the soft can packaging bag in real time, and utilizes the local bulge deformation to make the food in the packaging bag be impacted and change its position. When the liquid amount or pressure in the fluid bin 2 exceeds the set value, the one-way pressure valve is automatically squeezed open under the action of pressure. After the valve 51, it enters the transfer warehouse 5, so that the amount of fluid in the fluid warehouse 2 remains basically unchanged, so that the deformable membrane layer of the fluid warehouse 2 can be restored to its original position in time, and the circulation of liquid between different chambers is realized; a liquid cavity is provided in the pressure device 41, and the liquid cavity of the pressure device 41 is connected to the transfer warehouse 5 through a pipeline 52, and each liquid cavity is independently connected to the transfer warehouse 5. The pressure device 41 controls the amount of liquid delivered from the transfer warehouse 5 to the liquid cavity by adopting designs such as an adjustable speed micro electric pump, so that each pressure device can independently control the corresponding hollow linear conduit, thereby realizing effective control of the liquid pressure in the hollow linear conduit.

[0030] Furthermore, high-density particles are added to the liquid in the fluid chamber 2. Preferably, the high-density particles are solute particles soluble in the liquid or solid particles insoluble in the liquid. Examples of solutes soluble in the liquid include salts such as sodium chloride or potassium chloride, while examples of solid particles insoluble in the liquid include high-density particles such as silicon dioxide with an average particle size not exceeding 10 microns. The addition of high-density particles increases the impact of the high-pressure liquid in the hollow linear conduit 4 on the deformable membrane layer of the fluid chamber 2, facilitating effective position adjustment for larger and heavier fillings within the packaging bag.

[0031] Preferably, see Figure 2 The hollow linear conduit 4 is arranged obliquely upward. When rotating clockwise from the axis of the hollow linear conduit 4 toward the plumb line of the packaging bag, the included angle between the axis of the hollow linear conduit 4 and the plumb line of the packaging bag does not exceed 45 degrees. Preferably, the included angle is 15 degrees, 30 degrees, or 45 degrees. The angle of the hollow linear conduit is designed so that the ejected liquid exerts an oblique upward force opposite to the direction of gravity. This creates a synergistic effect between the upward impact force and the downward force of gravity, causing the food filling in the packaging bag to vibrate. This causes the deformable membrane layer 21 of the fluid reservoir 2 to locally move and adjust its position under the impact pressure of the hollow linear conduit 4 and the weight of the filling in the packaging bag.

[0032] Preferably, the auxiliary packaging device further includes a contour pre-sensing pressure device, the outer surface of which is provided with a force-sensing surface for sensing the distribution of cusps on the surface of the soft-canned food packaging bag. The force-sensing surface is made of a deformable material, and when the pre-sensing pressure device exerts equal pressure on the force-sensing surface, it adheres tightly to the packaging bag surface, thereby obtaining the actual contour of the packaging bag surface and determining the distribution of cusps on the packaging bag surface.

[0033] Preferably, the positions of the hollow straight conduits 4 are evenly distributed and the spray range covers the inner surface of the entire fluid warehouse. The pressure at the inlet end of any hollow straight conduit 4 is individually controlled by a pressure device, which can achieve coverage and control of the deformation of the deformable membrane layer surface of the entire fluid warehouse 2.

[0034] Preferably, the outlet end of the hollow linear conduit 4 does not contact the deformable membrane layer 21 on the inner surface of the fluid chamber 2. This design utilizes the liquid isolation between the outlet end of the hollow linear conduit and the inner surface of the fluid chamber 2 to prevent the liquid ejected from the hollow linear conduit 4 from causing excessive impact on the deformable membrane layer of the fluid chamber 2. This also prevents the impact on the filling in the packaging bag from being too sharp, thereby providing better protection for both the packaging bag and the meat-filled food inside.

[0035] Preferably, the auxiliary packaging device further includes an external support. The external support is a metal mesh restraining support capable of generating a certain pressure. After the filling food is adjusted to a suitable position in the soft can packaging bag, the external support is used to fix the packaging bag. After the subsequent vacuuming or freezing process, the external support is removed and recycled.

[0036] See also Figure 3 The method for using the auxiliary packaging device for canned meat with thorns containing soup of the present invention comprises the following steps:

[0037] S1, pre-determining the position of the sharp points on the surface of the soft can packaging bag: The soft can packaging bag is placed in the fluid jacket 1, and the shape pre-sensing pressure device is used to sense the distribution of the sharp points on the surface of the soft can packaging bag in a natural plumb state. During the pre-determining process of the sharp points on the surface of the soft can packaging bag, the force sensing surface is completely in contact with the surface of the soft can packaging bag, so that the contour of the packaging bag surface is replicated under the action of equal pressure, and the position of the sharp points on the surface of the soft can packaging bag is obtained;

[0038] S2, adjusting the surface profile of the fluid sleeve: according to the distribution of the cusp positions obtained in the previous step, the corresponding hollow linear conduit 4 is selected, the pressure device 41 at the corresponding position is started, and the corresponding hollow linear conduit 4 is used to spray liquid to impact the deformable film layer 21 to change the pressure at the cusp position on the surface of the packaging bag, thereby generating a local convex deformation, and then adjusting the position of the cusp by using the extrusion deformation. In this process, the shape pre-sensing pressure device is repeatedly used to sense the changes in the cusp on the surface of the packaging bag, and the surface profile of the fluid sleeve 1 is adjusted in a targeted manner until there are no obvious cusps on the surface of the packaging bag; the high-pressure liquid sprayed from the hollow linear conduit is carried out intermittently, and this design makes it possible for the barbed wire filled in the packaging bag to be impacted. The meat food uses its own gravity to adjust its position to allow for reaction time. Furthermore, when there is relatively little soup base, and the packaging bag is in a naturally plumb state and cannot gather or surround the sharp point, the soup base is gathered toward the sharp point by arranging the hollow linear conduit and adjusting the pressure of different pressure devices. The soup base is then concentrated toward the sharp point by increasing the impact and extrusion of liquid at other positions, so that the bone spurs of the meat food at the sharp point are fully surrounded by the soup base. The high-pressure liquid ejected from the hollow linear conduit then effectively impacts the soup base near the sharp point, thereby utilizing fluid motion to produce a flexible impact on the meat food at the sharp point, thereby adjusting its position and eliminating the sharp point on the packaging bag surface.

[0039] S3, adding an outer shape bracket to the soft can packaging bag: the outer surface of the packaging bag obtained in the previous step is shaped using a mesh binding bracket for vacuum sealing in the next process.

[0040] Taking a whole bone-in fish fillet with broth as an example, how to keep the plane direction of the main skeleton of the fish fillet and the fish bones parallel to the surface direction of the two sides of the packaging bag to avoid the fish fillet skeleton from breaking and puncturing the packaging bag is the primary goal. As for broken bone ingredients with soup, how to adjust the sharp edges of the broken bones to prevent the packaging bag from being punctured is the primary goal. In the existing production line process, after the filler food is filled into the soft can packaging bag, due to the randomness of the filling and the difference in the external dimensions of the packaging bag itself, the position of the filler food in the packaging bag is also random, which may cause the filler food itself to break or puncture the packaging bag later. After the auxiliary packaging device of the present invention is used to complete the position adjustment and packaging of the thorny meat soft can containing soup, it will effectively prevent the soft can packaging bag from being punctured, and can also provide consumers with a good consumer experience such as intact appearance and no broken fish bones, promote the sales of meat soft can products, and have significant social benefits.
