Technical Field

The invention relates to the technical field of food processing, in particular to food forming equipment, a food forming method and formed food.

Background

In the production of food such as candies and pastries, it is necessary to shape a powdery, pasty or pasty material into a specific shape. Similar confectionery products include pear syrup products, hawthorn products, sesame candy products, and the like. Taking haw products as an example, the haw products can be divided into raw material process and clinker process. The clinker preparation process includes steaming haw, compounding hot haw, grouting at 80 deg.c to produce the haw product, and curing. The raw material production process is to use the cold material after cooking to prepare the raw material and then scraping the raw material to produce the raw material to obtain the product. In general, the industrial production of the above-mentioned food is not only to consider the pouring and molding of the raw paste, but also to consider the problem of demolding of the molded product.

Existing, more advanced, automated equipment for forming confectioneries has been disclosed by the utility model patent entitled "confectioneries forming machine" with publication number CN 205337466U. The movable forming mechanism is provided with a die A plate and a die B plate hinged on a die base, the opening mechanism and the closing mechanism are used for respectively controlling the rotation of the die A plate and the die B plate around the die base so as to realize the opening and closing between the die A plate and the die B plate, and batch production flows of automatic candy pouring, forming and demolding are realized by matching with material pouring and demolding. However, in fact, in order to achieve the opening and demolding of the mold, the above-described molding apparatus needs to reset the opening and closing mechanism of the mold independently of the moving mechanism of the mold, the structure as a whole is more complicated, and coordinated control of the movement and opening and closing of the mold needs to be achieved.

Detailed Description

The present invention will be described in detail below with reference to the drawings and the specific embodiments, and in the present specification, the dimensional proportion of the drawings does not represent the actual dimensional proportion, but only represents the relative positional relationship and connection relationship between the components, and the components with the same names or the same reference numerals represent similar or identical structures, and are limited to the schematic purposes.

Fig. 1 is a schematic diagram of the present food forming apparatus, partially sectioned along the A-A direction to show structural details. Which comprises two opposite flexible support portions 11 operating in synchronization and on which flexible support portions 11 forming dies 111 are arranged in correspondence, fig. 1 is only one embodiment of a forming die 111, which may be integral or separate, and therefore fig. 1 should not be understood as a limitation of forming dies 111. A cavity 113 is formed in a surface of the molding die 111 on at least one side. The flexibility of the two sets of flexible supports 11 means that both sets of flexible supports 11 are flexible, i.e. locally change their direction of movement, at least in one direction, such as the movement path F in the figure. The flexible performance can be realized based on a specific flexible material, such as a belt of flexible materials like silica gel, rubber, etc., or can be realized based on a mechanical structure, such as a flexible chain formed by interconnection as shown in fig. 1. In the structure of fig. 1, in operation, the two sets of flexible support portions 11 pass through at least the mold clamping and shaping area A1, the demolding area A2 and the injection molding area A3. In the molding region A3, the two sets of flexible supporting portions 11 are not in contact with each other, so that a space is formed between the molding dies 111, and the raw paste is injected into the cavity 113 on the molding die 111 in the space. The two sets of flexible supporting parts 11 in the mold closing and shaping area A1 synchronously run oppositely and in a fitting way, so that the two sets of molding dies 111 keep surface fitting and close contact, and further, corresponding mold cavities 113 on the two sets of molding dies 111 form a molding space 113A which is basically closed, and the raw paste is closed in the molding space 113A and shaped gradually when moving or stopping in the mold closing and shaping area A1. When the two flexible supporting parts 11 are in opposite joint synchronous movement, the movement directions of the two flexible supporting parts are the same in the die assembly shaping area A1, so that the movement synchronization is ensured. In the demolding area A2, the two sets of flexible supporting parts 11 relatively move away from each other to separate the two sets of molding dies 111 from contact, the molding space 113A is opened, and a product obtained by solidifying and molding the raw paste in the molding space 113A is released from the mold cavity 113 after the mold cavity 113 is opened to realize demolding.

The flexible supporting part 11 of the food molding device with the chain structure as shown in fig. 1 is provided with a plurality of molding dies 111 along with the chain links, the molding dies 111 can be arranged on each chain link, or can be arranged at intervals of one or a plurality of chain links, and the molding dies 111 are provided with hollow mold cavities 113. The cavity 113 may be provided on either one of the two flexible support portions 11, but may be provided on both flexible support portions 11. Therefore, when the two sets of molding dies 111 are moved in the clamping and shaping area A1, the die cavity 113 can be necessarily closed to form a relatively closed molding space 113A, wherein the closing merely means that the raw paste in the die cavity 113 cannot leak out, and no sealing or other meaning is provided. In the case where the cavities 113 are provided in both sets of molding dies 111, the cavities 113 in both sets of molding dies 111 are not required to be identical in shape, and only the parting surfaces need to overlap, so that the end product can be molded in two parts to form the same whole at the parting position where the parting surfaces overlap. In general, the parting surfaces of the two sets of molding dies 111 are identical, so that the product has parting lines with equal sides, and no obvious shape distinction exists at the parting surfaces, which is merely a natural effect caused by the molding design. Compared with the prior art related to the background art, the two sets of forming dies 111 forming the forming space 113A of the food forming device of the invention are not arranged on the same die base, and a corresponding mechanism for opening the two sets of forming dies 111 or closing the two sets of forming dies 111 is not required. Essentially, the food forming device realizes the opening or closing of the forming space 113A by naturally changing the distance between the two groups of forming dies 111 while the device operates, so that no additional auxiliary mechanism is needed, the mechanism composition of the technical scheme is simpler, and the control method is relatively simplified.

Fig. 2 shows a partially schematic view of a food forming device made of flexible material having the above structure. Which has two sets of flexible supports 11 arranged opposite each other. The flexible support 11 has a cavity 113 formed therein. Since the two sets of flexible supporting parts 11 are made of flexible materials, a chain link structure and the like are not required to be arranged to realize movement according to a preset path, and therefore the forming dies 111 do not need to be arranged separately, which is equivalent to forming the forming dies 111 in the area where each row of die cavities 113 are located on the flexible supporting parts 11, and the forming dies 111 are flexibly connected based on material characteristics. Of course, the flexible material used for the two sets of flexible supporting portions 11 only solves the problem that the two sets of flexible supporting portions 11 move along the moving path F, and in order to realize stable driving movement without relative sliding, accessories such as chains, synchronous belts and the like for accurate synchronous driving are not excluded on the flexible supporting portions 11. The two sets of flexible supporting parts 11 realize the movement along different areas of the moving path F through a plurality of sets of guide wheels, and based on the movement, a mold closing and shaping area A1, a demolding area A2 and an injection molding area A3 are formed. In the mold closing and shaping area A1, the surfaces of the two groups of flexible supporting parts 11 are attached, so that a closed molding space 113A is formed by a mold cavity 113 on the molding mold 111, based on the fact that the two groups of flexible supporting parts 11 are made of flexible materials, a supporting device 114 is optionally arranged on the back surfaces of the two groups of flexible supporting parts 11, the supporting device 114 can slide with the flexible supporting parts 11 or between the two groups of flexible supporting parts 11, the two groups of flexible supporting parts 11 are supported towards the front surfaces of the two groups of flexible supporting parts 11 in the normal direction of the two groups of flexible supporting parts 11, and the problem that raw paste leaks due to expansion of the materials between the two groups of flexible supporting parts 11 and the opening of the molding space 113A is solved. In short, the supporting device 114 may be elastically fixed on the frame, so as to achieve a certain pressing force to the two sets of flexible supporting portions 11 to solve the sealing problem of the forming space 113A, and certainly, other setting manners of the supporting device 114 to achieve the effect are not excluded. In fig. 1 and 2, the two sets of flexible supporting parts 11 are generally shown to have different degrees of movement direction change to form the mold clamping and shaping area A1, the demolding area A2 and the injection molding area A3, and the applicant needs to say that, based on the technical concept of forming the expanded open demolding area A2 and the injection molding area A3 for feeding and demolding and sealing and shaping at the mold clamping and shaping area A1, the two sets of flexible supporting parts 11 are essentially not required to bend in directions when entering the mold clamping and shaping area A1 and exiting the mold clamping and shaping area A1, only one of them is required to deflect, so that similar schemes still fall within the scope of the invention.

Fig. 3 shows a further embodiment of the above solution. In order to realize the continuous recycling of the mold closing and shaping area A1, the demolding area A2 and the material injection molding area A3 in the use process, that is, the continuous molding of material feeding, molding and demolding, the flexible supporting part 11 can be in a closed annular structure as shown in fig. 3. The annular structure only needs to be in the technology of the scheme, so that the two groups of flexible supporting parts 11 are connected outside the die assembly shaping area A1 to form a ring at the two ends of the die assembly area A2 and the material injection shaping area A3. At this time, in the mold clamping and shaping area A1, the movements of the two flexible support portions 11 are synchronized and the directions are the same, meaning that the directions of the movements of the two annular flexible support portions 11 are opposite when seen from one side.

The use of the food product molding apparatus may be optimized by further designing the mold cavity 113 on the molding mold 111. Further optimized construction referring to fig. 4, fig. 4 is an enlarged partial schematic view of the partial cut-away location at a in fig. 3. The mold cavity 113 in the embodiment equivalent to that of fig. 1 and 2 has a problem of incomplete demolding in practical application, particularly because the single mold cavity 113 is integrally provided on the forming mold 111. Referring to the drawing of the foregoing embodiment of fig. 5, for the case of correspondingly disposing the mold cavities 113 on the two sets of molding dies 111 at the same time, which is equivalent to splitting the molding space 113A into the mold cavities 113 belonging to the two sets of molding dies 111, referring to the drawing of fig. 5, during the moving process, the mold cavities 113 on both sides are gradually separated, at this time, the molded candy and other products still adhere to the mold cavities 113 on one side due to the action of the mold cavities 113 and lack of disturbance from the outside, so that the mold cavities 113 cannot complete drawing of patterns in the preset drawing of patterns area A2, and the molded candy and other products may continue to be transported to other positions along with the flexible supporting portion 11.

Returning to the modified embodiment in fig. 4. In order to solve the problem that the mold cavity 113 may adhere to the molded product such as candy and thus it is impossible to achieve complete demolding of all the products in the demolding area A2, resulting in incomplete demolding, the mold cavity 113 may be provided as a separate body. That is, for the same mold cavity 113, it spans two adjacent molding molds 111, i.e. the mold cavity 113 is divided into a first sub-mold cavity 1131 and a second sub-mold cavity 1132, which are respectively disposed at corresponding positions on opposite sides of the adjacent molding molds 111, so that when it enters the mold clamping and shaping area A1, the adjacent molding molds 111 are bonded to form a complete mold cavity 113. Fig. 6 shows a schematic drawing of the demolding of the food-molding apparatus of fig. 4. It can be seen that in the solution presented in fig. 4 with the mold cavity 113 being composed of separate first and second sub-cavities 1131, 1132, demolding is obviously facilitated. During the operation and movement of the two sets of forming dies 111 along the respective movement paths F, as the two sets of forming dies 111 that enter the demolding area A2 earlier are far away, the second sub-cavity 1132 is opened first, at this time, another part of the product W is still clamped by the two sets of forming dies 111 that are still located in the mold clamping and shaping area A1, so that the product W will be demolded naturally with the second sub-cavity 1132 that enters the demolding area A2 earlier by the operation of the two sets of flexible supporting parts 11, so that the product W can be demolded in the demolding area A2 conveniently and collected in the demolding area A2.

Meanwhile, the following further technical solution is not excluded based on the embodiment in fig. 4. Fig. 7 shows a front view of the flexible support 11 according to one embodiment, optionally with or without the cavity 113, corresponding to the molding of only one cavity 113, the other side being a closed surface, without the cavity 113 being provided, the cavity 113 also preferably having the structural features shown in fig. 7. First, as shown in fig. 4, the first sub-cavity 1131 and the second sub-cavity 1132 of the split mold cavity 113 may be equally divided along the symmetry line of the parting plane. However, for each molding die 111 in a specific moving direction along the moving path F, the first sub-cavity 1131 and the second sub-cavity 1132 may be configured to be non-uniform, such that the first sub-cavity 1131 is located upstream of the moving path F relative to the second sub-cavity 1132, that is, the second sub-cavity 1132 always passes through the same point before the first sub-cavity 1131, and the first sub-cavity 1131 is located upstream of the moving path F. That is, the direction from the mold clamping and shaping area A1 to the mold releasing area A2, and the sub-cavities in the direction are sequentially named as a first sub-cavity 1131 and a second sub-cavity 1132. It is preferable to deviate the cavity center of the cavity 113 (which may be regarded as the position of the center of gravity of the article W) to the side of the first sub-cavity 1131, i.e., to make the parting surface area of the first sub-cavity 1131 larger than the parting surface area of the first sub-cavity 1131. In the process of entering the demolding area A2, the flexible supporting part 11 which firstly enters the demolding area A2 is far away to realize demolding, at this time, the large part of the product W in the first sub-cavity 1131 is actually demolded, while the small part in the first sub-cavity 1131 is remained in the first sub-cavity 1131, and the demolding of the first sub-cavity 1131 is completed after the flexible supporting part 11 continues to travel for the width distance of the forming mold 111. It is believed that achieving the above conditions requires that at least the area of the first sub-cavity 1131 along the interface of the flexible support 11 with the flexible support 11 on the other side be greater than the corresponding area of the first sub-cavity 1131. Of course, the area of the first sub-cavity 1131 cannot be too small for effectiveness, otherwise it may be difficult to clamp the product when the first sub-cavity 1131 is first demolded, and empirically, the first sub-cavity 1131 should be not less than 1/4 of the area of the first sub-cavity 1131, preferably 1/3, to accommodate the requirements of different product W hardness. Fig. 7 shows a solution by providing the first sub-cavity 1131 and the second sub-cavity 1132 at both side edges of the forming mold 111, respectively, so that such a solution is mainly considered to improve the area utilization of the forming mold 111, thereby improving the output efficiency of the apparatus, but a solution of a single side arrangement is not excluded. In the technical scheme of single-side setting, every two adjacent forming dies 111 can be grouped, the two forming dies 111 in the group are respectively provided with a first sub-die cavity 1131 on one side and a first sub-die cavity 1131 on the other side on opposite sides, and after entering a die assembly shaping area A1, the forming dies 111 in the group can be butted into a die cavity 113 and matched with the flexible supporting part 11 on the other side to form a forming space 113A.

Alternatively, as can be seen in the partial side schematic view of fig. 8, in an embodiment similar to that of fig. 1-3, stripper bars 1133 may be provided on the side of the two sets of flexible supports 11 in the stripping zone A2 adjacent to the surfaces of the two sets of flexible supports 11. The guiding means 13 may be arranged within the range of movement of the two sets of flexible supports 11 in the demolding zone A2, the demolding lever 1133 having a leading edge near the flexible supports 11 or surface, which contacts the side of the article W as it moves and touches the article W as it continues to move with the mold cavity 113, freeing the article W from the mold which has not been demolded. Fig. 9 shows an isometric view of the release rod 1133, which is merely illustrative of the release rod 1133, and virtually any shape and arrangement of the release rod 1133 that meets the flexible support 11 and does not interfere with the article W is acceptable. The use of the ejector pins 1133 can effectively prevent the problem of sticking to the side mold when forming a candy product such as sesame candy or the like having a strong adhesion. The release lever 1133 may be elastically provided on the frame, for example, connected to the frame by an elastic member such as a spring, so that when contacting the article W, it may be elastically deviated, and reliable release of the article W may be ensured while avoiding damage to the article W. In general, the release rod 1133 is not necessarily provided, and may be installed according to the degree of adhesion of the product W, for example, for the preparation of products such as pear syrup having low adhesion, it may naturally fall off after entering the release area A2 due to the low adhesion. The release lever 1133 may not be provided at this time.

For the embodiment of fig. 3, the demolding and blanking problem of the product W is solved by separating the mold cavity 113 into the first sub-mold cavity 1131 and the second sub-mold cavity 1132 and placing the sub-mold cavities on the adjacent molding mold 111 to realize the sequential demolding of the mold cavity 113 in the demolding area A2, but there is a potential problem. This can be illustrated by returning to the enlarged partial cutaway view shown in fig. 3. In the course of the molding die 111 or the flexible supporting portion 11 on the other side going from the injection molding area A3 into the mold clamping and shaping area A1, a gap is formed between the adjacent molding die 111 and the flexible supporting portion 11 on the other side due to the change of direction, and this gap may cause leakage of the raw paste, however, the leakage problem may be solved by providing a corresponding receiving device for recycling, so that it is acceptable. However, there is a problem in that the raw paste enters between the adjacent molding dies 111 (or between the adjacent flexible supporting portions 11 on the other side) and causes the clamping to cause the loose butt joint between the molding dies 111 (or between the flexible supporting portions 11 on the other side), which may affect the molding of the molded product W, for example, may cause serious problems such as burrs, dragging, and the like. This problem is particularly pronounced for thicker, harder or more powdery starting pastes. One notable example is the shaping of relatively hard fruits such as sesame candy.

Fig. 10 provides a modification based on the above embodiment. In order to avoid the problem of clamping during closing of the adjacent forming dies during entering the die closing and shaping zone A1, precise control of the attitude of the forming dies 111 (optionally including the flexible support 11 on the other side) during operation is intended to be achieved by the drive train design, so as to achieve the purpose of mutually matching the forming dies 111 existing in pairs. For the flexible supporting portion 11 formed by the forming dies 111 in pairs in sequence, only the side edges can be docked in advance in the process of entering the die assembly shaping area A1 from the material injection forming area A3 between the forming dies 111 in each group, so that the combined die cavities 113 can be formed at the docking edges, and the relative position and posture of the die cavities 113 can be maintained in the entering process, so that the die cavities 113 stably exist and receive the raw paste. The two adjacent molding dies 111 outlined by the dashed line in fig. 10 can be regarded as a group, and the mold cavities 113 are generally provided on opposite sides between the two molding dies 111 in the group.

In the solution of fig. 10, the flexible supporting portion 11 is designed to be located on the guiding device 13 at the junction of the injection molding area A3 and the mold closing and shaping area A1, and the guiding device 13 may be a driving wheel or a driven wheel. Which in fact achieves a gradual change of the direction of movement of the flexible support 11 in the injection molding zone A3 and in the clamp molding zone A1. While simultaneously taking into account the intended function of maintaining the attitude of the in-set forming die 111 unchanged during operation. In general, the guide 13 rotates circumferentially, the flexible supporting parts 11 enter and exit the guide 13 (corresponding to the injection molding area A3, the mold molding area A1) in different tangential directions, each two adjacent sets of molding dies 111 form one set, the butted portion between them forms the mold cavity 113, the guide 13 corresponds to each set of molding dies 111 in circumferential direction, the protruding part 131 is formed at the front position or the rear position contacting the flexible supporting parts 11, or the two sets of links between the two sets of molding dies 111 are connected (the front part refers to the first position, and the rear part refers to the last position in the direction of the moving path F, of the set of flexible supporting parts 11 formed by the two adjacent flexible supporting parts 11), the hollow part 131A can be formed between the protruding parts 131 of the guide 13 to prevent interference with the molding dies 111 of the flexible supporting parts 11, and the hollow part 131A is a plane connecting the adjacent protruding parts 131 or a concave surface recessed toward the center of the guide 13 connecting the root parts of the adjacent protruding parts 131. Nor does it exclude that the support portion 132 is provided for supporting the forming die 111 in a specific direction. By arranging the protruding parts 131 reasonably at the head or tail of each group of forming dies 111, one group of forming dies 111 can be tightened between the protruding parts 131, so that the two forming dies 111 of the group are straightened on the same plane, i.e. natural butt closure is achieved. This occurs when the flexible support 11 is brought into engagement or engagement with the guide 13 and is maintained as it travels along the guide 13. This means that when the material is fed in the injection molding area A3, the forming dies 111 in groups on the flexible supporting part 11 can be mutually closed before feeding, so that the problems of material clamping and material clamping during feeding are avoided, the molding problem of molding is avoided, and the quality problems of flash, thick molding edge, dragging and the like are avoided. Fig. 10 shows a chain drive solution, in which the projections 131, i.e. the teeth in the circumferential direction of the guide 13, are engaged by the chain into the flexible support 11. For other non-chain structures, a similar principle is still applicable, for example, if a synchronous belt is used, which may require that the pulleys have a regular polygon, and that the teeth of the synchronous pulley on each side are on the same line, which simultaneously defines the co-planar butt joint of the two forming dies 111 in a corresponding group to achieve their relative closure. The use of a timing belt instead of a conventional belt, which is mainly considered in terms of running synchronism, may cause misalignment between the sets of forming dies 111 and the sides of the polygonal pulley due to slipping, but this does not represent that the conventional belt drive cannot be used in the present application.

Fig. 11 shows a side view partially schematic of the guide device 13 in the chain drive version. Wherein the lighter grey lines show the position of the drive chain of the flexible support 11 during simultaneous operation. In order to achieve the function of opening and closing the forming dies 111 in groups without changing the relative attitude within the groups, each tooth of the guide means 13 is essentially provided for each group of forming dies 111 (the group consisting of two adjacent forming dies 111), the projections 131 are provided on the guide means 13 at intervals depending on the size of the guide means 13, so that, in operation, the groups of forming dies 111 are engaged at the same position within each group. Due to the non-nature of the links with the forming die 111, this does not first mean that there is a necessary link between the arrangement of the projections 131 and the number of spaced links, in other words that the arrangement of the projections 131 is determined by the forming die 111 in groups, not by the number of spaced links. It will be appreciated that in the case where the flexible support 11 is defined, it is relatively defined how the protrusions 131 are arranged in the circumferential direction of the guide 13. It is still important that the relative positions of the projections 131 and the forming die 111 in the direction of movement match, as previously described, the projections 131 are generally limited to being provided at the leading and trailing portions of the set of forming dies 111 and at the connecting links between the two sets, which three positions are shown in turn by a, b in fig. 11. This is the relative movement between the projection 131 and the forming tool 111, or determines the rotational phase of the guide 13, without actually changing the arrangement of the projection 131 on the guide 13. The protruding parts 131 are generally arranged to be connected with the plane of the adjacent protruding parts 131 or the curved surface concave inwards towards the rotating shaft of the guiding device 13, and no protrusion is generally arranged, so that interference with the flexible supporting part 11 is avoided, and the situation that the two forming dies 111 in the group are not tightly closed is avoided. In the solution of fig. 11, one forming die 111 occupies two links, and two adjacent forming dies 111 are in a group, so that the protruding portions 131 are repeatedly arranged in a cycle of four links, which is only one of the specific implementations of the solution. In practice, the forming die 111 may occupy only one link, such as the schematic diagram of fig. 14. At this time, the protruding portion 131 is required to be provided in each cycle with two chains, and the protruding portion is required to be repeated in the circumferential direction of the guide device 13. Fig. 14 shows two schematic views d and e of the forming die 111 at different positions on the links. The forming die 111 is fixed on a single chain link of the transmission chain of the flexible supporting part 11 and is arranged above one pin shaft of the chain link; the forming die 111 may be fixed to a single link of the transmission chain of the flexible support 11, straddling the pins at both ends of said link. This means that the relative position between the forming die 111 and the link to which it is connected is not critical, and it is important that a fixed connection is formed between the forming die 111 and the corresponding link, either by means of pins, keys or the like between the axes of the links (rotation of the forming die 111 on the axes is inhibited), or by means of welding, mechanical connection. The broken line g in the figure shows that the molding die 111 and the link are fixed to each other, and basically, the molding die 111 and the link are fixed to each other in the same order. It is conceivable that the more spaced links are only dependent on the number of links occupied by the forming die 111, so that the solution of correspondingly more links is not excluded. Of course, the above two solutions have advantages as the preferred solutions of the present application, whether the forming mold 111 occupies one chain link or two chain links, in that the forming mold 111 spans at most two chain axes, and it can be ensured that the chain is not bent at the portion spanned by the forming mold 111, so that the arrangement between the forming mold 111 and the corresponding driving chain is facilitated.

Fig. 12 shows a partially schematic side view in cross-section of the position of the guide means 13 in fig. 10 taken along the middle plane of the flexible support 11. This is mainly to explain how the guide 13 is supported between the forming die 111. The supporting portion 132 is not necessary as described above, and in the case of adding the support, the supporting portion 132 is provided corresponding to each set of the molding dies 111 in the circumferential direction of the guide 13, which is substantially the same as the periodic arrangement of the protruding portions 131. The top surface of the same supporting part 132 is a plane and is attached to the lower surfaces of the two molding dies 111 in the group, so that the two molding dies 111 in the group are supported by the top plane of the supporting part 132, and the coplanar butt joint of the two molding dies is ensured to close the mold cavity 113 therebetween. As shown in fig. 13, the base circle of the supporting portion 132 and the base circle of the protruding portion 131 may be separately provided and coaxially fixed by mechanical connection, such as bolting.

With the embodiments shown in fig. 1 and 3 and the other corresponding embodiments, there is still the problem of leakage during the passage from the injection molding zone A3 to the clamp molding zone A1, as already mentioned, in the flexible support 11 and the redirection, the leakage can be collected by the receiving means provided on the back of the molding die 111 and the flexible support 11 on the other side, which does not affect the implementation of the overall solution, but which can indeed be further optimized. At least two optimization schemes of fig. 15 and 16 are provided herein. I.e., to ensure that the gap between adjacent forming dies 111 remains closed when relative rotation occurs therebetween.

As shown in fig. 15, for the forming mold 111 disposed on different axes, such as fig. 1 and 3, and other similar technical solutions, the forming mold 111 has transition arcs 111A at bottom edges of two sides, the center of the transition arcs 111A is coaxial with the rotation axis of the forming mold 111 on the corresponding side, and the sum of radii r1 and r2 of the transition arcs 111A on two sides at the same gap should be equal to the rotation axis distance L of the gap. In general, of course, r1+r2=l may be directly applied in consideration of the problems of convenience in manufacturing, assembly, fool-proofing, and the like. Fig. 15 is essentially applicable to the case of at least one link spaced between the forming dies 111, where L is the product of the pitch and the number of intermediate spaced links. Accordingly, a flexible support 11 may be provided, for example. Accordingly, for the embodiment shown in fig. 10 or 11, it is only required that the corresponding outermost sides of the molding dies 111 having the outermost sides on both sides in each adjacent die set 11G satisfy the same arc transition so that the adjacent die sets 11G can be kept in contact with each other.

Fig. 16 provides another embodiment. Fig. 16 is mainly applied to the case that no intermediate link exists between adjacent molding dies 111, and at least two arrangements a and b shown in fig. 16 can be provided. In the case of fig. 16 a, the forming mold 111 is the width of a single chain link (the gray line is a schematic of a chain), the forming mold 111 is only arranged above the rotating shaft of the single chain link, at this time, the back of the forming mold 111 is arranged at two sides of the rotating shaft O to form arc transition, the arc radiuses of the two sides are not necessarily equal, but the circle centers of the two sides are coaxial with the rotating shaft O, which is similar to the embodiment of fig. 15, so that when the forming molds 111 rotate relatively, the gap between the forming molds 111 is always closed by the contact of the arc surfaces of the adjacent forming molds 111, and the leakage of the raw paste is ensured. In case b of fig. 16, the forming die 111 may still be arranged across the links based on the width of the individual links, in which case the forming die 111 is arranged between two rotational shafts O, each rotatably connected to a rotational shaft O. The adjacent forming dies 111 share the rotation axis O therebetween, and when the adjacent forming dies 111 are rotatably disposed on the same rotation axis O, the contact surfaces therebetween are closed. The b case of fig. 16 is a side schematic. To more clearly illustrate this, it can be seen from the schematic diagram of fig. 17 that the forming mold 111 is respectively provided with a sleeve on the rotation shaft O at both sides thereof, and the two sides of the forming mold 111 are staggered, as shown in fig. 17, so that when the adjacent forming molds 111 are connected, the outer surfaces of the adjacent forming molds 111 are mutually attached, and the surfaces of the forming molds 111 are also kept continuously closed in at least line contact during rotation, or continuously air-closed in surface contact, such as the tangential plane closed of the passing outer arc surface and the forming mold 111 or the inner arc surface closed by matching on the forming mold 111. Generally, the arc surface of the inventor preferably cooperates with the concentric arc surface with equal diameter machined on the surface of the adjacent forming die 111 to close the gap, which can remove the space possibly existing in the gap and prevent the raw paste from remaining in the gap.

Fig. 18 shows a further development of the invention. The improvement is particularly suitable for the situation that color separation or material separation forming is needed, such as the existing production process of the agaricus bisporus pear syrup, namely, under similar technical conditions, the formed fruit is required to be provided with two different colors or two different materials. A similar function may be achieved by adding a suitable feed port 14 at the injection molding zone A3. At this time, the cavity 113 is generally provided in each of the two sets of molding dies 111, the injection molding region A3 is divided into two storage spaces isolated from each other by the partition plate 141 provided in the injection molding region A3, specifically, the space is divided into the first storage bin 14A and the second storage bin 14B by the partition plate 141 provided in the space between the two sets of molding dies 111, and the isolation means that the raw material pastes on both sides of the feed port 14 are not mixed with each other. The first material paste is stored in the first storage bin 14A, the second material paste is stored in the second storage bin 14B, when the machine is started, the material pastes in the first storage bin 14A and the second storage bin 14B naturally enter the die cavity 113 of the forming die 111 of the same flexible supporting part 11, when the forming die 111 moves into the die closing and shaping area A1, the die cavity 113 is closed to form a forming space 113A, and a formed part forms an integral shape formed by two materials in the forming space 113A. The lower edge of the sprue 14 is generally disposed at a transition between the cavity 113 of the forming die 111 and the cavity 113 of the flexible support 11 on the other side in the injection molding zone A3. If a completely different first and second raw paste are used, the finished product has a composition with different side portions. In practice, two raw paste materials with partially identical and partially different components can be prepared, especially, different plant pigments are added to form raw paste materials with different colors, and the steps are performed to form candy products with two colors or foods such as medicinal and edible herbal concentrated soft extract honeyed pills. The material separating plate 141 may be inserted into the material feeding opening 14, and the lower portion of the material separating plate 141 is located substantially near the contact point of the two flexible supporting portions 11, so as to prevent the materials in the first storage bin 14A and the second storage bin 14B from being mixed. When the production of the two-material product is not required, the material partition plate 141 can be taken out to realize the molding of a single material. As shown in fig. 19, a movable scraping device 142 may be provided in the inlet 14 to press the paste of the raw material or the like so that the raw material can sufficiently fill the molding die 111, which is not necessary, and is generally used in molding of the raw material having poor fluidity. The scraping means 142 may be a rotating roller placed in the feed opening 14, which rotates against the surface of the flexible support 11 when feeding material, compacting the material in the forming die 111. When the feed inlet 14 is divided into the first storage bin 14A and the second storage bin 14B, the scraping device 142 may be respectively disposed in the first storage bin 14A and the second storage bin 14B. The structure of the flexible supporting portion 11 may form a conical space in the injection molding area A3, or may horizontally move in the injection molding area A3, and the scraping device 142 may use a scraping plate that reciprocally moves on the surface of the flexible supporting portion 11.

The above-described solutions are only some implementations of the overall solution of the food forming device, on which various embodiments are actually possible. Based on the above description, the two sets of forming dies 111 at the end of the mold closing and shaping area A1 are attached, and the attachment between the two sets of forming dies 111 can be ensured to meet the requirements by further providing a suitable pressing device on the back surfaces of the two sets of forming dies 111. And the illustrated solution is for illustrative purposes only and does not limit the length of the specific travel paths within the mold clamping and shaping zone A1 and the demolding zone A2 and the injection molding zone A3. In fact, especially for the section of the mold-clamping and shaping zone A1, the person skilled in the art can optionally provide the necessary environmental conditions for the shaping of the articles in the mold-clamping and shaping zone A1 with corresponding heating and cooling means. A station for applying a release agent may also be provided before the two sets of molding dies 111 enter the injection molding zone A3 to improve the release of the article W in the release zone A2. For example, a row brush or other oiling device is disposed on the rotary or non-rotary forming die 111 and the flexible support 11 on the other side before entering the injection molding area A3, more specifically, the position of the feed port 14, and a layer of vegetable oil or other usable demolding release material is coated into the mold cavity 113.

The food product forming apparatus may be arranged in a generally vertical or near vertical direction as shown so that the feeding in the injection forming zone A3 and the stripping in the stripping zone A2 are accomplished substantially by means of the raw paste gravity and the mold opening and closing. However, the above technical solution is not excluded to be changed into a horizontal, approximately horizontal arrangement, so that specific lengths and specific layouts of the mold clamping and shaping area A1 and the mold releasing area A2 and the injection molding area A3 are not required either. The above-mentioned technical solutions that the two sets of flexible supporting parts 11 may bend or serpentine along a suitable path in the mold-closing and shaping zone A1, the mold-releasing zone A2 and the injection molding zone A3 are not disclosed, but remain within the scope of the present application. Moreover, the overall fit of the two sets of flexible support portions 11 in the mold clamping and shaping area A1 can be set to be a serpentine S-folded manner, which can ensure the shaping time of the product W and provide a satisfactory production speed, for the sake of reducing the floor space and sharing the environmental holding equipment.

The food forming equipment can be used for processing and preparing various candy products. For example, the method can be applied to the technical field of casting molding of various paste candies such as Chinese herbal medicine honey pills, pear syrup, chinese herbal medicine syrup, granulated sugar, crystal sugar, hawthorn sugar, sesame cake, nine-steaming nine-boiling sesame pills and the like, can realize the omnibearing molding of the product W, and can also be used for shaping other various paste and slurry materials or double-color double-material molding of products.
