Description

Waxy food with thin layer sandwich, processing equipment and manufacturing method thereof

Technical Field

The invention relates to the field of foods, in particular to equipment for manufacturing a thin-layer sandwich waxy food, the thin-layer sandwich waxy food manufactured by the equipment and a method.

Background

The starch is used as a raw material, so that various cake foods with sandwich stuffing can be manufactured, such as a dough with sandwich stuffing on the market at present is very popular, and the glutinous rice flour, the modified starch and the flavoring agent are blended and manufactured into a waxy crust, and various stuffing such as fruit/sweetened bean paste stuffing/cream and the like on the inner layer are wrapped, so that rich and multi-layer mouthfeel can be brought, and the food is called as 'Dafu' in Japan and is mostly called as 'snow-charming' in China.

In order to facilitate the consumer to make the snowy girls at home, currently, a merchant pushes out independently packaged waxy sheaths, the waxy sheaths have good ductility, the waxy sheaths are stretched by pulling and wrapping stuffing, and the consumer can smoothly make the snowy girls by folding the excessive waxy sheaths to the bottom, so that the consumer only needs to purchase the stuffing according to own taste preference.

In order to make the snow-beautiful skin have a visual effect of better eye, the merchant also supplements and adds food pigment in the blending process of the waxy skin raw material so as to manufacture waxy skins with different colors. For partial consumers, the added pigment can generate a question on food quality safety, so that partial target sales groups are reduced to a certain extent, the snowy skin presents a single color, and the whole is lack of layering sense and penetrating sense, so that the snowy skin has an optimization space;

in the other development thinking direction of the snowy and charming skin product, the waxy skin is endowed with flavor by adding the flavoring agent into the waxy skin raw material, but the waxy skin is endowed with single taste brought by the flavoring agent, the original fresh and slightly sweet taste of the waxy skin is changed, and the taste is lack of layering.

The sandwich mode is added into the inner layer of the waxy outer skin, so that the fresh and slightly sweet original taste of the waxy outer skin can be maintained, and the taste brought by the sandwich layer can enrich the overall taste of the waxy outer skin; meanwhile, the visual effect of wrapping the sandwich color layer in the clear epidermis can be visually presented by adopting the sandwich with different color and luster from the waxy outer skin.

At present, most of the methods for producing waxy sandwich cake foods are carried out by inserting an injection needle into the center of a waxy base material and injecting stuffing, but the stuffing is required to have higher fluidity so as to be convenient to inject in the way of processing the stuffing by injecting the center; meanwhile, the characteristic of high fluidity of the inner stuffing also enables the inner stuffing to be in an amorphous form in waxy foods to be injected, so that the waxy sandwich cake foods are in a bulk form; if the rolling operation is carried out on the waxy sandwich cake food to expect to obtain the planar sandwich waxy food, the filling with higher fluidity is easy to be rolled to cause the filling with higher fluidity to present uneven sandwich shape when being pressed due to the amorphous flowing direction, thereby influencing the quality; in addition, when the glutinous rice is further flattened to form a thin-skin sandwich glutinous food with the thickness of 5-8mm, the outer glutinous rice skin is extruded by the filling core stuffing and overflows due to overlarge pressure, so that the filling core-flattening process is not suitable for manufacturing the target product.

For producing and manufacturing the thin-layer sandwich waxy food, the feasibility of a mode of wrapping the upper waxy leather material and the lower waxy leather material by overlapping the sandwich layers and sealing the upper leather material and the lower leather material is higher, but no equipment can finish the manufacturing of the product on a large scale in a mass production mode at present.

As a preferable scheme, raw materials such as glutinous rice flour, corn starch, tapioca flour, white granulated sugar, milk powder, acetylated distarch phosphate, hydroxypropyl starch, amylase and the like are compounded to prepare a glutinous rice skin raw material group p0 which is not divided into snowy and beautiful mother skin through stirring, stewing and heat preservation, the glutinous rice skin raw material group p0 in a heat preservation state is correspondingly fed into a material cavity a1 of the upper material feeding unit 22 and the lower material feeding unit 12, the heat preservation stirring of the glutinous rice skin raw material group p0 is carried out through a double-screw stirring mechanism a3, and the pumping of a single-screw pumping mechanism a4 in a material discharging pipe is matched, the upper and lower feeding units 22 and 12 can stably extrude waxy epithelium and lower epithelium p10 which are flat through the feeding opening of the upper and lower feeding units 22 and 12, respectively, the upper and lower conveying belts 21 and 11, and the width of the feeding opening of the upper and lower feeding units 22 and 12 can be set to obtain the lower epithelium p10 with the width not smaller than that of the epithelium, in the embodiment, the width of the lower epithelium p10 is set to be 125mm, the width of the epithelium is about 110mm, the thicknesses of the epithelium and the lower epithelium p10 are all 4-5mm, and the viscosity caused by waxy starch is reserved to a certain extent;

along the transmission direction, the lower conveyor belt 11 adopts a sectional arrangement scheme of a front lower conveyor belt 111 and a rear lower conveyor belt 112, the edge pressing device 13, the lower edge cutting device and the edge folding device 4 are sequentially arranged on two sides of the front lower conveyor belt 111, a leveling roller set serving as a leveling device 5 is arranged between the front lower conveyor belt 111 and the rear lower conveyor belt 112 which are transmitted in the same direction, and the slitting device 6 is arranged above the rear lower conveyor belt 112. Compared with the scheme that the leveling device 5 is suspended on the upper side of the single lower conveyor belt 11, the leveling roller set is arranged between the front lower conveyor belt 111 and the rear lower conveyor belt 112 which are transmitted in the same direction, so that the leveling roller set can keep a plane integrally between the overlapped leather p31 and the upper and lower trimming leather (p 21, p 11) in an overlapped state when in operation, and the adverse phenomena that the overlapped leather p31 is possibly irregular and has direction transmission deviation and is integrally distorted are reduced; in addition, when the front lower conveyor belt 111 and the rear lower conveyor belt 112 are arranged in a sectional mode, the front lower conveyor belt 111 adopts a conventional conveyor belt equipment scheme capable of smoothly completing the transmission of the lower leather p10, and the rear lower conveyor belt 112 is adjusted to be a multi-layer metal mesh conveyor belt with an anti-sticking coating, so that the multi-layer metal mesh conveyor belt has higher strength and is more suitable for the slitting process of the slitting device 6.

The mode that the two sides of the lower leather material p10 on the front lower conveyor belt 111 are pressed to form thin layers by adopting a multi-pinch roller type pressing wheel set with gradually reduced height can gradually press from high to low for the first time, so that the elastic recovery phenomenon of the waxy lower leather material p10 is eliminated, the target preset thickness is reserved, and the initial single-side edge pressing width is preferably 4-5 mm; meanwhile, the multi-pinch roller type pinch roller presses two side edges of the lower leather material p10 on the front lower conveyor belt 111 to form thin layer edges, and the effect of shape regularity is further achieved, so that the part of the thin layer edge residual material p12 to be cut off can be reduced, and a small amount of raised embossing p36 in the middle part of the lower leather material p10 can be reduced when the edge pressing device 13 presses the lower leather material p 10.

The upper trimming device adopts upper cutter groups 23 arranged on two sides of the upper conveyor belt 21, specifically, upper cutters are fixed to a frame through a rotary bolt, and the edges of the upper cutters can partially cut the excess materials on two sides of the upper materials by adjusting the angle of the upper cutters and the horizontal distance between the two upper cutters, so that the upper materials form an upper trimming material p21 with two sides in a regular straight side shape; the residual materials cut off by the upper leather materials are transmitted along with the conveyor belt, and the positions of the two upper discharging guide blocks 24 at the rear end of the upper cutter set 23 are correspondingly adjusted, so that the residual materials are guided by the guide surfaces of the upper discharging guide blocks 24 and discharged out of the upper conveyor belt 21; as an improvement measure, in order to better prevent the residual materials from affecting the working environment, a collecting tank can be additionally arranged at the lower end of the upper conveyor belt 21 to collect the residual materials;

the lower trimming device is arranged in a mode of arranging lower cutter groups 14 on two sides of a front lower conveyor 111, arranging a lower discharging guide block 15 at the rear end of the lower cutter groups 14 and arranging a collecting groove at the lower end of the conveyor, fixing the lower cutters to a frame through a rotary bolt, correspondingly adjusting the lower cutter groups 14 in a mode of adjusting the upper cutter groups 23, so that the thin layer edges on two sides of a lower leather p10 transmitted along with the conveyor are cut, forming a lower trimming leather p11 with the thin layer edges on two sides in a regular side shape, and controlling the single-side width of the trimmed regular side thin layer edges to be 12 mm+/-1 mm in a matched mode in the embodiment; correspondingly adjusting the positions of the two lower discharging guide blocks 15 at the rear end of the lower cutter set 14, so that the thin-layer edge surplus material p12 is guided by the guide surfaces of the lower discharging guide blocks 15 and discharged outside the front lower conveyor belt 111, and a collecting tank additionally arranged at the lower end of the lower conveyor belt 11 can collect the thin-layer edge surplus material p 12;

in the hemming device 4 of the present embodiment, the hemming device is an integral guide rail formed by a pair of folded slope sections 41, a slope section 42, an inner rotation folded section 43 and a guide rail section 44 which are connected to each other and form the same continuous guide surface along the conveying direction, when the lower Ji Bianpi material p11 is driven by the front lower conveyor belt 111 to move to the hemming device 4 continuously toward the rear end, the folded slope sections 41 on the edges of the two sides are driven to be obliquely vertical from the horizontal direction to the oblique direction, so as to form a vertical edge p13 facing obliquely upwards, and when the lower Ji Bianpi material p11 is driven to the range section of the slope section 42, the vertical edge p13 is slidingly conveyed along the slope section 42 and continuously maintains the same angle as the slope section 42. Preferably, the ramp surface sections 42 are preferably 40 ° -65 ° which ensures that the two side edges p13 remain inclined sliding along the ramp surface sections 42 without rolling or collapsing inwardly.

After the slope surface section 42 forms the edge part p13 on the two side thin layer edges, the thin layer stuffing is supplied to the surface of the lower leveling edge leather p11 between the two edge parts p13 by the feeding port of the stuffing supply unit 3, and according to different processes, a slurry spraying mechanism 31 and a spraying mechanism can be adopted as the stuffing supply unit 3 to singly thin layer spray-coat or thin layer-spray paste stuffing like chocolate slurry and fruit slurry to the upper end of the opening port p14 of the lower leveling edge leather p 11; when powder stuffing such as green tea powder, cocoa powder and the like is selected to be independently added, a powdering mechanism 32 can be selected as a stuffing supply unit 3, and the powder stuffing is brushed in a rotating way through a rotating brush roller 321 in a powder containing cavity 320, so that the powder stuffing is scattered downwards in a thin layer through a screen hole 322 to the upper end of an opening p14 of a lower trimming skin p 11; of course, after the powder filling is sieved and spread on the thin layer, the upper end of the opening p14 of the lower leather p11 is leveled and then the thin layer is supplemented with shower coating or thin layer spraying paste filling, then the powder filling is sieved and spread again to form a multi-layer flavor filling layer, and a sufficient length of slope surface section 42 is arranged to provide sufficient equipment installation space for the filling supply unit 3 with different types or combinations of types so as to facilitate the application of the thin layer filling, in this embodiment, the thin layer shower coating of the paste filling p15 is firstly carried out on the opening p14 of the lower leather, and then the thin layer sieving of the powder filling p16 is carried out on the upper part of the opening of the lower leather on which the thin layer paste filling p15 is shower coated.

After thin-layer stuffing is applied to the upper end of the opening p14 of the lower trimming skin p11, the upper trimming skin p21 conveyed by the upper conveying belt 21 is correspondingly overlapped to the upper end of the opening p14 of the lower trimming skin p11, and at the moment, the upper trimming skin p21 correspondingly overlaps the thin-layer stuffing; as the front lower conveyor belt 111 continues to move toward the rear end, the standing edge portion p13 moves along the slope surface section 42 to the inner folded surface section 43, the standing edge portion p13 is transferred along the slope surface section 42 to the inner folded surface section 43 to be folded horizontally, the thin layer edges are folded over the two side edges of the upper trimming material p21 to form a folded material p31, the folded region of the folded material p31 passes through the inner channel of the guide rail section 44 and is heated, and the folded region formed between the thin layer edges folded horizontally and the upper trimming material p21 is heated to be bonded better.

In order to better reduce the inward bending convex portion p35 which may be generated when the two upright edge portions p13 turn inwards along the inward rotation folded surface section 43, so as to improve the regularity of the folding edge sealing area p32 on two sides of the folded leather p31 and improve the folding degree compactness between the upper leather and the lower leather p10, a folding guide plate 8 may be arranged above the inward rotation folded surface section 43, the angular arc surfaces 81 at two ends of the lower part of the folding guide plate 8 face the inward rotation folded surface section 43, a channel through which the upright edge portions p13 can pass is formed between the angular arc surfaces 81 and the opposite surfaces of the inward rotation folded surface section 43, and when the upright edge portions p13 pass through the channel between the angular arc surfaces 81 and the opposite surfaces of the inward rotation folded surface section 43, a gap is formed between the angular arc surfaces 81 and the inward rotation folded surface section 43, so that the folding regularity when the upright edge portions p13 turn to fold and wrap the upper leather can be improved, and particularly, the occurrence of the inward bending convex portion p35 can be reduced, and the phenomenon that the two sides of the inner edge portions p35 are formed to be unqualified after the leveling device 5 is further enlarged is avoided; meanwhile, the straight arc surface 82 in the center of the lower part of the wrapping guide plate 8 faces the surface of the lower conveying belt 11, a passage through which upper and lower trimming materials (p 21, p 11) can pass after being overlapped is formed between the straight arc surface 82 and the facing surface of the lower conveying belt 11, and when the upper and lower trimming materials (p 21, p 11) at the opening part pass through the passage between the straight arc surface 82 and the facing surface of the lower conveying belt 11, the straight arc surface 82 gently presses the upper trimming material p21, so that bubble arches possibly occurring between the upper and lower trimming materials (p 21, p 11) can be prevented, and the upper and lower trimming materials (p 21, p 11) at the opening part are ensured to be aligned and laminated and leveled.

The laminated skin p31 with the sandwich is conveyed to the leveling roller set with the front lower conveyor 111, with a gap left between the upper and lower rollers of the leveling roller set. The gap size of the gap is adjusted so that the overlapped leather p31 is leveled to form a thin leather shape with the thickness of 6.5+/-0.5 mm after passing through the leveling roller set. In the process of rolling and leveling the overlapped leather p31, the thin-layer stuffing is maintained in the area enclosed by the upper leather and the lower leather p10 and is not extruded from the overlapped edge sealing area p32, the overlapped leather p31 is smoothly rolled and leveled, and the traction effect of the leveling roller set on the overlapped leather p31 also assists in driving the upper leather and the lower leather p10 to smoothly move along the transmission direction.

The laminated leather p31 is transferred to the rear lower conveyor 112 after being flattened, then the slitting device 6 carries out hot-pressing and cutting segmentation on the laminated leather p31 in a thin leather shape to form a segmented structure with the length of about 75mm, the manufactured thin-layer sandwich waxy food p34 is formed by folding and edge sealing of the upper folding and the upper folding of the leather on the lower leather on the left side and the right side, the front side and the rear side are in a pressed and edge sealing structure, the thin-layer paste and/or the thin-layer powdery raw material are positioned in the surrounding area of the folded and edge sealing and the pressed and edge sealing between the leather and the lower leather, the thickness of the leather and the lower leather is 3.2 plus or minus 0.3mm, the thickness of the thin-layer sandwich is 0.8 plus or minus 0.2mm, the whole thickness of the thin-layer sandwich waxy food p34 is 6.5 plus or minus 0.5mm, and the area size is about 75mm multiplied by 115mm.

The thin sandwich waxy food p34, in appearance, presents a transparent surface layer, a visual effect of the natural color with a flavor sandwich layer in the middle, is set to be about 75mm by 115mm in size, and presents a shape with a wider width between two overlapping edge sealing areas p 32.

Based on the performance of waxy skin raw materials for manufacturing the snow-charming skin, when the thin sandwich waxy food p34 is held, pressed and sealed at two side parts and the narrower side is stretched, the thin sandwich stuffing can still be kept in a surrounding area within a reasonable range of 120-130mm, and especially the wrapping and sealing area p32 keeps the original structural form; and the whole size is similar to a square after being stretched, so the novel snow-charming skin can be used as a novel snow-charming skin to replace the current snow-charming skin. The prepared snow-beautiful girls can observe the color of the sandwich stuffing through the upper and lower leather materials, the overall visual effect of transparent surface layer and sandwich color is presented, and the thin sandwich stuffing can effectively endow the snow-beautiful girls with more layers of flavors besides the fresh and sweet taste; of course, the sandwich stuffing and the sweet taste of the food can be directly eaten, and the food is also suitable for being eaten as food with other sweet taste wrapped by the outer layer of the auxiliary wrapping.

Furthermore, in order to facilitate packaging, the novel snow-charming skin can be packaged in a mode of sieving powder in a starch layering way and placing the starch layering powder in a heat-sealing packaging box after superposition in the current snow-charming skin production process, and the novel snow-charming skin can be packaged in a large scale in a mature subsequent packaging process.

Example 2

As shown in fig. 10-14, in order to better ensure the quality stability of the thin-layer sandwich waxy food, especially the thin-layer sandwich waxy food p34 containing pasty filling, the thin-layer filling is sealed in the upper wrapper, the lower wrapper, the wrapping and overlapping edge sealing area p32 'and the pressing and cutting edge sealing area p33', so that the back-sticking phenomenon of a small amount of thin-layer filling in the pressing and cutting edge sealing area is more effectively avoided. Specifically, in this embodiment, based on the technical solution of embodiment 1, the control unit controls the slurry spraying mechanism 31 and the powder spraying mechanism 32 to take the corresponding preset frequency as the feeding frequency, and the thin-layer filling is fed in a manner of corresponding to intermittent thin-layer shower coating and thin-layer screening powder filling.

In this way, the filling was added to the surface of the lower Ji Bianpi p11 in a thin intermittent arrangement. When the upper trimming skin p21 is overlapped to the upper end of the opening p14 of the lower trimming skin p11 with the stuffing intermittently arranged, the opposite edge p13 is folded by the flanging device 4 to form an overlapped skin p31', and the overlapped skin p31' is leveled by the leveling device 5, the pasty stuffing and/or the powdery stuffing are intermittently arranged in a sandwich manner, and the sectional area p37' is in a direct stacking form without any stuffing between the upper trimming skin p21 and the lower trimming skin p 11. The slitting device 6 is set to perform hot-pressing and slitting on the segmented region p37 'between two adjacent sandwich parts at the set slitting frequency, so that the thin-layer sandwich waxy food p34' in which the thin-layer stuffing is sealed in the upper wrapper, the lower wrapper, the wrapping and edge sealing region p32 'and the press-cutting and edge sealing region p33' can be completed.

In order to better improve the accuracy of hot-pressing the superimposed skin p31' between two adjacent sandwich portions by the slitting device 6, the apparatus can be improved individually or jointly by the following two improvements:

one of them can carry out the improvement of equipment through the mode of addding elasticity and pacify dull and stereotyped 7, through being provided with the elasticity that once goes up and down cylinder 71 control to go up and down in dusting mechanism 32 feed inlet rear end and pacify dull and stereotyped 7 in this embodiment to set up elasticity and pacify dull and stereotyped 7 and be the shape that takes the plane to extend after bending downwards from the arc from the front end to the rear end, and correspond to the opening p14 width equal with lower neat's skin material p 11. When the lower trimming material forming the upper edge p13 on both sides is driven by the front lower conveyor belt 111 to move towards the rear end along the conveying direction, the elastic trimming plate 7 is controlled by the control unit, the second set frequency is used as the trimming working frequency, the lifting cylinder 71 drives the elastic trimming plate 7 to reciprocate downwards, so that the elastic trimming plate 7 trims the surface of the lower trimming material p11 at the upper end part of the opening p14, and then the lower trimming material p11 and the elastic trimming plate 7 slide relatively, so that the thin-layer stuffing can be trimmed, and the stuffing can be uniformly coated; and for the scheme that sets up elasticity and pacify dull and stereotyped 7 in drenching thick liquid mechanism 31 rear end, this embodiment is with elasticity and pacify dull and stereotyped 7 and set up in the dusting mechanism 32 rear end, through this position setting, the powdered filling can cover paste filling, so less to elasticity and pacify the adhesion influence of dull and stereotyped 7 bottom plate part, effectively reduce elasticity and pacify the wire drawing phenomenon that paste filling probably produced when dull and stereotyped 7 bottom plate resets and moves up to avoid the wire drawing to drop and influence the form at thin layer filling district border.

When the elastic pacifying plate 7 pacifies the lower trimming skin p11 of the opening part, the arc-shaped front end part can ensure the movement smoothness of the lower trimming skin p11, and when the control unit controls the elastic pacifying plate 7 to move upwards again, the thin-layer stuffing at the front end part is relatively flat, so that when the leveling device 5 levels the sandwich-attached laminated skin p31', the size occupied by the sandwich part is more uniform between any two adjacent sandwich parts. Based on this, the slitting device 6 can perform hot-pressing slitting on the non-stuffing area of the overlapped leather p31' between two adjacent sandwich parts more accurately at a reasonable slitting frequency;

as another scheme, paste stuffing with deep color and/or powder stuffing can be adopted as the material of the thin-layer stuffing, and the sensing unit 16 arranged between the leveling device 5 and the slitting device 6 is matched with equipment to serve as a component for assisting the slitting device 6 to accurately perform hot-pressing cutting on the overlapped leather p31' between two adjacent sandwich parts.

The thin-layer fillings with chromatic aberration with the upper and lower wrappers are distributed in a discontinuous sandwich mode in the overlapped wrappers p31', after being leveled by the leveling device 5, the sensing unit 16 enables the control unit to control the slitting device 6 in a chromatic aberration sensing mode to accurately perform hot-pressing and cutting on the non-filling areas.

Compared with the thin-layer sandwich waxy food p34 'prepared in the embodiment 1, the thin-layer sandwich waxy food p34' prepared in the above manner improves the quality stability of products, and simultaneously avoids adverse effects of influence on other thin-layer sandwich waxy foods p34 'caused by discomfort in hand feeling due to holding of a back-sticking part and adhesion of back-sticking stuffing due to pulling of a pressing and cutting edge sealing part p33' held by both hands.

The foregoing embodiments may be partially modified in numerous ways by those skilled in the art without departing from the principles and spirit of the invention, the scope of which is defined in the claims and not by the foregoing embodiments, and all such implementations are within the scope of the invention.
