Description

Technical Field

[0001] The utility model relates to a rice cake bran wrapping machine, belonging to the technical field of food machinery. Background Art

[0002] Ciba, a traditionally popular food in China's rice-producing regions, is made primarily from steamed and pounded glutinous rice, often blended with other ingredients to enhance its appearance, flavor, and aroma. For example, a layer of bran can be applied evenly to the surface of the ciba. Existing ciba production machinery is suitable for this purpose.

A fan is also provided at the end of the vibration mechanism to blow off excess bran on the surface of the strips, so as to ensure that all the strips are evenly coated with bran. The excess bran falls into the material trough below the second chain mesh conveyor 311 and re-enters the bran bin 321 for recycling with the help of the power system.

[0004] Since the structure of the semi-finished glutinous rice cake is not so strong, it is easy to loosen the semi-finished glutinous rice cake by using a vibrating chain conveyor belt.

[0019] like Figure 1 The glutinous rice cake bran wrapping machine shown in the figure comprises a frame 1, a support trough 2 installed on the upper part of the frame 1, a lifting device 4 installed on the frame 1 and located on one side of the support trough 2, a chain mesh conveyor 3 installed on the support trough 2 and partially located in the support trough 2; a lower hopper 5 installed at the upper opening of the support trough 2 and connected to the outlet of the lifting device 4, the lower hopper 5 is located above the chain mesh conveyor 3 and close to the feeding side of the chain mesh conveyor 3; a blast bin 6 installed at the upper opening of the support trough 2 and above the chain mesh conveyor 3, the blast bin 6 is located at the lower hopper 5 close to the feeding side of the chain mesh conveyor 3 On the side of the outlet direction, the blast bin 6 is connected to the blower 61 installed at the bottom of the frame 1, and the air outlet of the blast bin 6 faces the chain mesh conveyor 3; the upper end opening is installed at the bottom of the support groove 2, and the bottom outlet is connected to the recovery bin 7 of the feed port of the lifting device 4. The bottom plate of the support groove 2 corresponding to the upper end opening of the recovery bin 7 is also provided with an opening, and the opening is located below the opening of the blast bin 6 and is separated by a certain distance; the control box 8 is installed on one side of the support groove 2, and the control circuit is installed in the control box. The control circuit is connected to the blower 61, the lifting motor 41 in the lifting device 4 and the conveying motor 31 of the chain mesh conveyor 3.

[0020] The bran material is sent into the discharge bin through the lifting device, and the discharge bin discharges the material to the glutinous rice cake on the chain mesh conveyor belt. The wind in the blast bin can blow up the excess bran material that is not adhered to the glutinous rice cake. Part of it falls into the recovery bin, and part of it will stick to other surfaces of the glutinous rice cake to form a package.

[0021] In this embodiment, the air outlet of the blast chamber 6 is spaced a certain distance from the opening of the recovery chamber. Thus, when the glutinous rice cake passes through the discharge opening of the discharge chamber 5, the discharge opening sprinkles the bran onto the glutinous rice cake. Due to the viscosity of the glutinous rice cake (high water content), the bran that contacts the surface of the glutinous rice cake adheres to the surface. As the bran covering the upper portion moves toward the air outlet, starting with the topmost bran, the air volume increases as it approaches the air outlet, and the excess bran is gradually blown into the blast chamber, thereby adhering to the bottom and sides of the glutinous rice cake, forming a wrap. Although the bottom surface is blocked by the chain mesh wires, leaving more bran that is not attached to the top surface, the relatively thin wires and wide mesh widths between the wires allow a relatively large amount of bran to adhere to the bottom surface of the glutinous rice cake, resulting in a better taste for the finished glutinous rice cake. Example

[0022] As a further design of Example 1, Figure 2 As shown in the figure, the blast bin 6 includes a blast chamber, which consists of a square bin 62 and a triangular bin 65. The triangular bin 65 is close to the discharge port side and consists of the outer bottom surface of the discharge bin 5 and a side plate connected to the support groove. The square bin 62 is connected to the triangular bin 65 and is close to the output direction of the chain mesh conveyor belt. An air outlet rod 63 is provided on the top surface of the square bin, which passes through the top surface and is perpendicular to the top surface. The air inlet at one end of the air outlet rod 63 is connected to the blower 61 through a pipeline (the hose is not drawn). The air outlet is provided at the bottom of the air outlet rod 63. The air outlet is located above the chain mesh conveyor belt and faces the incoming material side of the chain mesh conveyor belt.

[0023] To better meet the specifications of customers' glutinous rice cake products, a sleeve body 64 is installed on the outer side of the top of the square chamber 62 of the blast chamber 6. The air outlet rod 63 is inserted into the sleeve body 64 and tightened by a fastening bolt set on the sleeve body 64. This structure allows the position of the air outlet rod to be adjusted up and down, thereby changing the position of the air outlet and the chain conveyor belt, and adjusting the force of the air blowing on the glutinous rice cake.

[0024] To ensure the air jet is positioned to best meet the needs of facing the glutinous rice cakes and the recovery bin, a triangular body 66 is provided at the bottom of the air outlet rod 63. The bottom surface of the triangular body 66 is vertically connected to the air outlet rod 63. The length of the triangular body 66 is equal to the width of the chain mesh conveyor 3. The air jet is arranged along the length of the triangular body on the inclined surface of the triangular body facing the feed side of the chain mesh conveyor. This design, with the air jet being inclined and positioned at an acute angle to the feed side of the chain mesh conveyor, achieves the optimal effect of jetting air to the bran material as in Example 1.

[0025] In this example, the material raising device 4 is a spiral material raising machine. The material raising motor 41 is installed on one side of the top of the material raising pipe 42, connected to the spiral shaft by a belt or chain, and the spiral shaft is provided with a material raising screw 43. The lower part of the material raising pipe 42 is provided with a feed port, which is connected to the bottom outlet of the recovery bin. The upper part of the material raising pipe 42 is provided with an outlet, which is connected to the top of the lower silo through an inclined pipe. The recovered bran material is sent to the lower silo 5 again, thereby realizing the automatic recycling of the bran material.

[0026] In this example, the chain mesh conveyor belt 3 includes a driving wheel, a driven wheel, and a chain mesh mounted on the driving and driven wheels. The driving wheel is connected to the conveying motor via a sprocket and chain. The driving wheel is mounted lower than the driven wheel. Auxiliary supporting rollers, mounted on a support frame and located between the driving and driven wheels, support the chain mesh so that its upper portion is horizontal, resulting in a triangular cross-section. This structure facilitates recycling and increases the contact space between the bottom surface of the glutinous rice cake and the bran, reducing obstruction from the lower chain mesh.

[0027] In order to better meet the requirements of recycled materials and new materials being mixed and discharged from the lower hopper, in this example, the lower hopper 5 includes a blanking inclined plate 51 located below the discharge port of the lifting device, the high end of the blanking inclined plate 51 is close to the discharge port side of the lifting device, and the low end is located at the discharge port of the lower hopper. A lower hopper feed port is opened on the lower hopper above the discharge port of the lower hopper, and a feed inclined plate 52 is set at the outermost edge of the feed port of the lower hopper into the lower hopper. The lower end of the feed inclined plate 52 is suspended and faces the blanking inclined plate 51, and a closing plate 53 is set on the side opposite to the outermost edge of the feed port of the lower hopper. The closing plate 53 is an L-shaped plate, and the vertical plate end of the L-shaped plate is connected to the edge of the feed port of the lower hopper, and the connecting end of the vertical plate and the horizontal plate of the L-shaped plate faces the feed port of the lower hopper.

[0028] The support trough 2 consists of an inclined bottom plate and two vertical trough plates installed on both sides of the inclined bottom plate. The inclined bottom plate is lowered from the discharge side of the chain mesh conveyor to the feed side. The tops of the two vertical trough plates of the support trough 2 are provided with L-shaped trough edges. The square bin 62 of the blast chamber is formed by a bin cover covering the L-shaped trough. The end face of the bin cover near the output direction of the chain mesh conveyor is provided with a baffle extending toward the chain mesh conveyor. The side opposite to the end face is open and connected to the triangular bin 65. This buckled structure is convenient for installation and maintenance. The triangular bin 65 has a larger space, which is convenient for blowing up and dropping bran for recovery.

[0029] The technical solutions given in the specific implementation manner are used to illustrate the technical solutions of the utility model, rather than to limit the utility model. Any changes based on the technical solutions of the utility model fall within the scope of protection of the present invention.
