Description

Technical Field

[0001] The present invention relates to an integrated system for making an edible wrapping film and simultaneously filling a filling, and more particularly to a technology for continuously producing and reducing costs for making a wrapping film and filling a filling at the same time. Background Art

[0002] In the processing of the food industry, most of the existing sausage fillings are processed using synthetic protein casings, natural animal casings or plastic outer skins instead of casings. In this way, the taste of the casing is single or inedible, and there is also a process of repeatedly adding casings during processing. The process is relatively cumbersome. If you need to process jam or cheese products, you need an additional independent outer packaging. If you need to change the taste of the edible outer shell, the cost will be relatively high. For the traditional processing scheme to carry out the above processing, a variety of processing equipment and procedures are required to complete, and the comprehensive processing cost is relatively high. Summary of the Invention

[0003] To solve the problems existing in the above technology, the present invention provides a technology that reduces processing equipment and procedures and reduces processing costs.

[0004] An integrated system for making an edible wrapping film and simultaneously filling a filling provided by the present invention includes a filling filling machine and a sodium alginate filling machine. The filling filling machine supplies and extrudes the filling, and the sodium alginate filling machine supplies and extrudes the wrapping film. The wrapping film wraps the filling in the middle to form an edible food.

[0005] Preferably, the filling of the filling filling machine is meat, jam, cheese, seafood, vegetarian, dessert, and different tastes of fillings are selected; the sodium alginate in the sodium alginate filling machine is a sodium alginate solution.

[0006] Preferably, it further includes a rolling and pressing structure located on the downstream side of the extruder. The rolling and pressing structure includes an upper rolling and pressing transmission rotating shaft, a lower rolling and pressing transmission rotating shaft, an upper rolling and pressing transmission belt and a lower rolling and pressing transmission belt. The upper rolling and pressing transmission belt is arranged on the upper rolling and pressing transmission rotating shaft, and the lower rolling and pressing transmission belt is arranged on the lower rolling and pressing transmission rotating shaft.

[0007] Preferably:

[0008] A discharge pump, a filter and a discharge pipe are sequentially connected between the sodium alginate filling machine and the extruder;

[0009] The extruder includes an extrusion feed head, an extrusion storage bin and an extrusion film outlet. The discharge pipe is connected to the extrusion feed head. The extrusion film outlet is arranged at one end of the storage bin. The extrusion feed head is connected to the sodium alginate extrusion storage bin.

[0010] Preferably, a segmentation structure is provided between the extruder and the rolling and pressing structure, and the segmentation structure is used for segmenting the produced food;

[0011] The segmentation structure includes an upper moving plate and a lower moving plate. The upper moving plate has an upper concave opening, and the lower moving plate has a lower concave opening. When the upper moving plate and the lower moving plate move relatively closer, segmentation is performed through the upper concave opening and the lower concave opening. Correspondingly, an upper concave transport groove is formed on the upper rolling and pressing conveyor belt, and a lower concave transport groove is formed on the lower rolling and pressing conveyor belt. The upper concave transport groove and the lower concave transport groove correspond to each other for conveying.

[0012] Preferably, a segmentation structure is further included. The segmentation structure is composed of a first pressing boss and a second pressing boss. There are a plurality of first pressing bosses on the upper rolling and pressing conveyor belt, and a plurality of second pressing bosses on the lower rolling and pressing conveyor belt.

[0013] Preferably, the length of the lower rolling and pressing conveyor belt is longer than that of the upper rolling and pressing conveyor belt; a cutting structure is provided on the downstream side of the upper rolling and pressing conveyor belt, and the cutting structure is used for cutting the segmented food.

[0014] Preferably, a detachable plasticizable filling head is provided at the discharge port of the filling extruder.

[0015] Preferably, the filling extruder and the extruder are respectively fixed on a fixing frame.

[0016] Preferably, the sodium alginate filling machine is used for filling sodium alginate, and sodium alginate is used for forming a packaging wrapping film; a curing liquid spraying structure is provided at the upper end of the extrusion storage bin.

[0017] The working method of the integrated system of the present invention includes the steps of: adding filling into the filling machine and adding sodium alginate into the sodium alginate filling machine. The sodium alginate filling machine extrudes the wrapping film, and at the same time, the filling machine extrudes the filling. The extruded filling is wrapped by the wrapping film extruded by the sodium alginate to form an edible food.

[0018] Preferably, sodium alginate enters the filter through a discharge pump, is filtered, then enters the packaging filter wrapping film extruder through a discharge pipe, and then enters the extrusion storage bin through an extrusion feed head, and a ring-shaped film is extruded to form a wrapping film. At the same time, the filling in the filling machine is extruded through the filling extruder. At this time, the wrapping film wraps the filling because it is extruded first, and the filling is extruded later and is located in the inner cavity of the wrapping film. In this way, after the wrapping film is extruded, the filling can be better wrapped without leakage;

[0019] Through the action of the sectioning structure, the wrapped materials are pinched into sections of materials, and then enter between the lower rolling die-pressing conveyor belt and the upper rolling die-pressing conveyor belt, and are conveyed towards the cutting structure. During the conveying process, the connected sections of materials are cut by the cutting structure, and the cut materials are conveyed towards the conveyor belt, and then enter the next process through the conveyor belt.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The filling machine and the sodium alginate filling machine work together. One provides the filling, and the other provides the wrapping film, and different types of wrapping films can be replaced at any time, so as to provide wrapping films of different materials. The wrapping film forms an outer film after extrusion, and the filling enters the middle and is wrapped by the outer film; continuous processing of the wrapping film is realized, that is, when it is necessary to supplement the sodium alginate of the wrapping film material, there is no need to stop the machine to replace the wrapping film, but directly add materials to the sodium alginate filling machine for continuous production, which is very convenient to use. In addition, through the film pressing structure, the filling structure wrapped by the extruded wrapping film can be die-pressed and transported, which is convenient for subsequent sectioning and cutting processes.

[0022] 2. Through the setting of the discharge pump and the filter, it is convenient to control the discharge of materials, and filter some particulate materials to control the particle size within a certain range, or avoid the mixing of some impurities, and improve the safety level.

[0023] 3. The sectioning structure provides two types. One is the upper moving plate and the lower moving plate, which realize pinching through the reciprocating movement up and down; the other is the first die-pressing boss and the second die-pressing boss structure that cooperate up and down.

[0024] 4. Edible sodium alginate replaces the traditional wrapping film, and there is no need to replace the wrapping film, so continuous production can be carried out, and the production cost is reduced. Description of the Drawings

[0040] Example 1:

[0041] An integrated system provided in this example for making an edible wrapping film and simultaneously filling stuffing includes a stuffing filling machine 1 or 3 and a sodium alginate filling machine 2 or 4. The stuffing filling machine 1 or 3 supplies the extruded stuffing, and the sodium alginate filling machine 2 supplies the extruded wrapping film. The wrapping film wraps the stuffing in the middle to form an edible food.

[0042] The stuffing of the stuffing filling machine 1 or 3 is meat, jam, cheese, seafood, vegetarian, dessert, etc., and different tastes of stuffing are selected; the sodium alginate in the sodium alginate filling machine 2 or 4 is a sodium alginate solution. The meat specifically refers to various meats such as pork, chicken, duck, and fish, the jam refers to various existing types of jam foods, and the cheese is cheese and related derivatives; different tastes include sour, sweet, bitter, spicy or other tastes.

[0043] The stuffing filling machine 1 or 3 and the sodium alginate filling machine 2 or 4 work together. One provides the stuffing and the other provides the wrapping film, and different types of wrapping films can be replaced at any time, so as to provide wrapping films of different materials. The wrapping film forms an outer film after extrusion, and the stuffing enters the middle and is wrapped by the outer film; continuous processing of the wrapping film is realized, that is, when it is necessary to supplement the sodium alginate, the wrapping film material, there is no need to stop the machine to replace the wrapping film, but the material can be directly added to the sodium alginate filling machine for continuous production, which is very convenient to use. In addition, through the film pressing structure, the structure of the stuffing wrapped by the extruded wrapping film can be pressed and transported, which is convenient for subsequent segmentation and cutting processes.

[0044] Example 2:

[0045] An integrated system for making an edible wrapping film and filling the filling at the same time provided in this embodiment includes a filling filling machine 1 or 3 and a sodium alginate filling machine 2 or 4. A filling extruder 9 is arranged at the discharge port position of the filling filling machine 1 or 3; the sodium alginate filling machine 2 or 4 is arranged on one side of the filling filling machine 1 or 3;

[0046] Specifically, as Figure 1 and Figure 2 shown, two different types of filling machines are given. Figure 1 In the middle is the integrated filling machine, that is, the main filling filling machine 3 and the sodium alginate filling device 4 are integrated together, that is, the two share the bottom base frame. Figure 2 They are two independently arranged filling filling machines 1 and sodium alginate filling machines 2.

[0047] Combined with Figure 3 、 Figure 4 and Figure 14 shown, the sodium alginate filling machine 2 or 4 is connected to the wrapping film extruder 8, and the filling extruder 9 penetrates through the inner cavity of the wrapping film extruder 8;

[0048] The rolling die pressing structure 12 is located on the downstream side of the wrapping film extruder 8. The rolling die pressing structure 12 includes an upper rolling die pressing transmission rotating shaft 12-2, a lower rolling die pressing transmission rotating shaft 12-4, an upper rolling die pressing conveyor belt 12-1 and a lower rolling die pressing conveyor belt 12-3. The upper rolling die pressing conveyor belt 12-1 is arranged on the upper rolling die pressing transmission rotating shaft 12-2, and the lower rolling die pressing conveyor belt 12-3 is arranged on the lower rolling die pressing transmission rotating shaft 12-4. Specifically, the upper rolling die pressing transmission rotating shaft 12-2 and the lower rolling die pressing transmission rotating shaft 12-4 can be rotated under the drive of a motor, and the surrounding upper rolling die pressing conveyor belt 12-1 and lower rolling die pressing conveyor belt 12-3 are driven to perform circular motion accordingly.

[0049] Preferably, a discharge pump 6, a filter 7 and a discharge pipe 5 are sequentially connected between the sodium alginate filling machine 2 or 4 and the wrapping film extruder 8; the discharge pump 6 is used to quantitatively extrude the wrapping film raw material in the sodium alginate filling machine 2 or 4. As a preferred solution, a filter 7 is provided. The filter is a filter screen structure or other existing types of filters for particle filtration to control the particle size, reduce large particles or remove impurities.

[0050] Such as Figure 14As shown in the figure, the wrapping film extruder 8 includes an extrusion feeding head 8-1, an extrusion storage bin 8-2, and an extrusion film outlet 8-3. The discharge pipe 5 is connected to the extrusion feeding head 8-1. The extrusion film outlet 8-3 is provided at one end of the storage bin 8-2. The extrusion feeding head 8-1 is connected to the extrusion storage bin 8-2. The extrusion feeding head 8-1 inputs sodium alginate into the extrusion storage bin 8-2, and then extrudes it from the annular extrusion film outlet 8-3 to form an annular film. The extrusion pipe 9-2 of the filling extruder 9 passes through the extrusion storage bin 8-2 and the extrusion film outlet 8-3, so that the filling can be extruded from the middle part, and the annular film extruded from the extrusion film outlet 8-3 just wraps the filling coming out from the middle, forming a filling structure wrapped by a wrapping film. Sodium alginate can be selected from existing materials suitable for use as a wrapping film.

[0051] It further includes a segmentation structure 11, and there are two implementation manners for the segmentation structure 11. The first implementation manner is: the segmentation structure 11 is composed of a first molding boss 71 and a second molding boss 72. There are multiple first molding bosses 71 on the upper rolling molding conveyor belt 12-1, and multiple second molding bosses 72 on the lower rolling molding conveyor belt 12-3. Multiple groups of the first molding bosses 71 and the second molding bosses 72 cooperate with each other. When they are close, a pinching structure can be formed to press and separate the whole section of the filling wrapped by the wrapping film into a segmented structure. The pinching structure in this way is very stable, combining the transportation process and the pressing and pinching process into one process, making the whole process smooth. During the pinching process of the filling wrapped by the wrapping film, dislocation is not likely to occur, and it is clamped at the position between two adjacent groups of molding bosses during the transportation process, improving the pressing and pinching time period (that is, maintaining the pinching action during the transportation process to make the adhesion section more stable).

[0052] Figure 3 、 Figure 4 It is a schematic diagram of the extrusion and molding of square or rectangular materials. Edible sodium alginate 15 passes through the extrusion feeding head 8-1, enters the extrusion storage bin 8-2 of sodium alginate inside the sodium alginate wrapping film extruder 8, and then enters the extrusion film outlet 8-3 to form an annular film and be extruded. Then it passes through the rolling molding device 12 (where the rolling molding device is divided into an upper rolling molding conveyor belt 12-1 and a lower rolling molding conveyor belt 12-3). There are molding bosses on the upper rolling molding conveyor belt 12-1 and the lower rolling molding conveyor belt 12-3 of the rolling molding device. When the upper and lower rolling molding conveyor belts respectively make clockwise and counterclockwise circular motions, the molding bosses on the two conveyor belts can be well aligned, forming a narrow gap in the middle. The filling wrapped by sodium alginate is brought into the two conveyor belts and continuously segmented and extruded through the narrow gap. The filling is segmented and wrapped, and the wrapping film inside the position where the filling wrapped by sodium alginate is extruded comes into direct contact and adheres, thus forming a semi-finished material 19 of continuously extruded filling connected by a thin film.

[0053] Embodiment 3:

[0054] Preferably, in this embodiment, a segmented structure 11 is provided between the wrapping film extruder 8 and the rolling molding structure 12. The segmented structure 11 of this embodiment is a second implementation mode, and the segmented structure 11 is used to pinch the produced food;

[0055] Combination Figure 5 and Figure 6 As shown, the segmented structure 11 includes an upper movable plate 111 and a lower movable plate 112, wherein the upper movable plate 111 has an upper concave opening 61, and the lower movable plate 112 has a lower concave opening 62. When the upper movable plate 111 and the lower movable plate 112 move relatively close to each other, the segments are formed by the upper concave opening 61 and the lower concave opening 62; the upper movable plate 111 and the lower movable plate 112 are staggered in the vertical direction, so that when they are close to overlap, the upper concave opening 61 and the lower concave opening 62 can be well combined. The pinching is performed, and the pinching degree can be adjusted, that is, it is adjusted according to the viscosity of the sodium alginate used, that is, when the upper concave opening 61 and the lower concave opening 62 are more integrated, the pinching pressure formed is greater, and the bonding pressure of the wrapping film segments is greater, and a greater pinching effect can be obtained; correspondingly, an upper concave transport groove 63 is formed on the upper rolling molded conveyor belt 12-1, and a lower concave transport groove 64 is formed on the lower rolling molded conveyor belt 12-3, and the upper concave transport groove 63 and the lower concave transport groove 64 correspond to each other for transportation. After the pinching action is completed, the cooperation of the upper concave transport groove 63 and the lower concave transport groove 64 can well guide the transportation of the filling wrapped in the wrapping film, so as to avoid the filling wrapped in the wrapping film from deviating from the position and coming off the conveyor belt when pinching.

[0056] In this embodiment, another type of segmented structure 11 is provided, which is different from the segmented structure in Embodiment 1. Here, the upper movable plate 111 and the lower movable plate 112 are mainly moved back and forth. When they are relatively close, the upper recessed opening 61 and the lower recessed opening 62 are placed close and staggered, so that the filling wrapped in the wrapping film in the middle position can be squeezed and segmented. The upper movable plate 111 and the lower movable plate 112 can be driven to move back and forth through the cooperation of a cylinder or a motor gear, for example. The lifting and lowering driving method of the upper movable plate 111 and the lower movable plate 112 belongs to the prior art and will not be described here.

[0057] Figure 5 , Figure 6 , Figure 7 , Figure 8 It is a schematic diagram of the segmented structure 11 when processing cylindrical materials. Figure 5 , Figure 6 It is a schematic diagram of the up and down movement of the segmenting device 11. Figure 7 ,Figure 8 This is a schematic diagram of the knurling process after putting in the materials. The edible sodium alginate 15 passes through the extrusion feeding head, enters the extrusion storage bin 8-2 inside the wrapping film extruder 8, and then enters the extrusion film outlet 8-3, forming an annular film that is extruded. Subsequently, the filling 16 is wrapped by the already extruded wrapping film with a certain toughness after passing through the filling extruder 9, and then is placed on the upper rolling die-pressing conveyor belt 12-1 and the lower rolling die-pressing conveyor belt 12-3. At this time, the two conveyor belts move clockwise and counterclockwise respectively. Grooves (upper concave transport groove 63 and lower concave transport groove 64) are provided in the middle of the two die-pressing conveyor belts, which can allow the cylindrical wrapping film and the filling it wraps to be smoothly transported to the next process. At the same time, the segmentation device 11 is started. The segmentation device has two components, which form a smaller clamping cavity (upper concave opening 61 and lower concave opening 62) through up and down movement. Therefore, the filling is segmented and wrapped, and the film inside the position where the filling wrapped by the wrapping film is squeezed (the knurling position) adheres, thus forming a semi-finished material 19 of continuous filling connected by a thin film.

[0058] Example 4:

[0059] In a further preferred embodiment, the length of the lower rolling die-pressing conveyor belt 12-3 in this embodiment is longer than that of the upper rolling die-pressing conveyor belt 12-1; a cutting structure 13 is provided on the downstream side of the upper rolling die-pressing conveyor belt 12-1, and the cutting structure 13 is used to cut the food into sections.

[0060] Figure 9 、 Figure 10 、 Figure 11 This is a schematic diagram of the segmentation method for square or rectangular materials. Figure 9 This is the state without putting in the materials. Figure 10 、 Figure 11 When putting in the materials, during the movement of the semi-finished material 19 pressed out on the lower rolling die-pressing conveyor belt 12-3, it is cut into required segments by the cutting structure 13, then transported to the conveyor belt and then transported to the required downstream process.

[0061] The cutting structure 13 adopts existing movement methods such as up and down reciprocating movement, accurately dropping the position of the pointed knife onto the convex platform of the lower rolling die-pressing conveyor belt 12-3, and at the same time, the adhered part of the semi-finished material 19 pressed out is cut into required segments. That is, the tip of the cutting structure 13 is driven by a cylinder or a motor-driven lift to perform reciprocating up and down movement to cut at the already knurled position.

[0062] Preferably, the cutting position is located on the adjacent side of the second die-pressing convex platform 72 of the lower rolling die-pressing conveyor belt 12-3. In this way, the second die-pressing convex platform 72 and the tip of the cutting structure 13 are closely adjacent to form a staggered cut, so the cutting effect is better, faster than single-edge cutting and with a better cutting effect.

[0063] In another embodiment, when applying the segmented structure 11 in Embodiment 3, the cutting is directly completed when pinching the joints through the upper concave opening 61 and the lower concave opening 62. That is, when the filling wrapped with sodium alginate is sent between the upper rolling die-pressing conveyor belt 12-1 and the lower rolling die-pressing conveyor belt 12-3, the cutting action is completed. In this embodiment, the joint pinching action and the cutting action are carried out simultaneously, thus eliminating the need to set up the cutting structure 13 downstream.

[0064] Figure 10 、 Figure 11 The cylindrical extruded semi-finished material 19 is cut into required segments by the cutting device 13 during transportation, and then transported to the conveyor belt and then to the required process.

[0065] Preferably, in combination with Figure 3 , a shapeable filling head 9-1 is detachably provided at the discharge port of the filling extruder 9. The shapeable filling head 9-1 can be replaced with different shapes according to needs, so that the shape of the filling wrapped with the extruded wrapping film can be quickly adjusted, such as cylindrical, square and other structures, which is very convenient to use.

[0066] Preferably, the filling extruder 9 and the wrapping film extruder 8 are respectively fixed on the fixing frame 17.

[0067] Preferably, the sodium alginate filling machine 2 or 4 is used for filling sodium alginate, and sodium alginate is used to form the packaging wrapping film; a curing liquid spraying structure 10 is provided at the upper end of the extrusion storage bin 8-2. At the same time, the curing liquid spraying device 10 located at the upper end of the wrapping film extruder 8 sprays the curing liquid, so that the extruded wrapping film is cured into a film with a certain toughness.

[0068] Combined with Figure 14 shown, the curing liquid spraying device 10 has a connected spraying pipeline 10-2 and a spraying outlet 10-3. A switch 10-1 is provided on the spraying pipeline 10-2, and the flow rate of the spraying pipeline 10-2 can be controlled by the tightening action of the switch 10-1. In addition, the spraying outlet 10-3 is located at the port position of the film outlet 8-3, so that the film material is sprayed with the curing liquid for contact and rapid curing after coming out.

[0069] The curing liquid is, for example, an aqueous solution of calcium chloride, an aqueous solution of calcium lactate or an aqueous solution of calcium gluconate, and the concentration is, for example, 0.5 mol / L, or 1 mol / L or 1 M. The curing liquid spraying device 10 is provided with a switch 10-1 for controlling the spraying of the curing liquid.

[0070] Sodium alginate passes through the extrusion feeding head 8-1, enters the storage bin 8-2 inside the wrapping film extruder 8, and then enters the extrusion film outlet 8-3 to form an annular film that is extruded. At the same time, the curing liquid spraying device 10 located at the upper end of the wrapping film extruder 8 sprays the curing liquid to cure the extruded sodium alginate into a film with a certain toughness. Such a structure realizes the use of sodium alginate that is not easy to form a film, that is, the sodium alginate stock solution forms an annular film after being transported and extruded, and then a stable film wrapping film is formed after spraying the curing liquid, and then the filling can be wrapped to form an edible food.

[0071] The sodium alginate solution is quickly cured by contacting with the calcium ions in the curing liquid to form a food film structure with enhanced toughness, thereby obtaining a sodium alginate wrapping film.

[0072] In the preferred embodiment, through the co-extrusion process of edible sodium alginate, a new processing method is provided for the production of various shaped products. It utilizes the advantages of edible sodium alginate (sodium alginate has strong thickening and stability, can increase the viscosity and stability of food, prevent the separation and precipitation of components in food, thereby improving the quality and taste of food. Dietary fiber source: Sodium alginate is a natural polysaccharide rich in dietary fiber. Appropriate intake can increase the supply of dietary fiber, promote the normal function of the digestive system, prevent constipation, and help control blood sugar and cholesterol levels. Health benefits: Sodium alginate can reduce serum cholesterol, triglycerides and blood sugar, and prevent diseases such as hypertension, diabetes and obesity. In addition, it can also inhibit the accumulation of harmful metals in the body and has antioxidant and anti-inflammatory effects) and flexible filling technology. The traditional wrapping film shell is replaced by edible sodium alginate, and the production process can be continuous without changing the wrapping film. In addition, the sodium alginate wrapping film shell can be used for the wrapping film application of various foods (meat products, vegetarian foods, jams, cheeses, etc.). The products obtained in this way can be used for freezing, frying and baking.

[0073] The sodium alginate solution is, for example, an aqueous sodium alginate solution. When used, it is mixed with water as needed (in a mass ratio of 1% or 2% or 5% or 10% or 20% or 30%) to obtain a viscous fluid, and then a film is formed after extrusion. To improve the toughness of the film, in the preferred embodiment, a solution containing calcium ions is sprayed using the curing liquid, and the calcium ions combine with the sodium alginate solution to form a gel to form a film with good toughness, making the food quality better.

[0074] In other embodiments, the sodium alginate applied is, for example, an edible gel, specifically, it can be existing polysaccharide gels, edible gelatin, gum arabic, agar and carrageenan. It should be noted that the use of the curing liquid is a preferred embodiment, which is used as needed and a suitable curing liquid is selected.
