Description

Technical Field

[0001] The invention relates to the technical field of food production, in particular to a production process and production equipment for snow-coated bean paste. Background Art

[0002] Snow-covered red bean paste is a classic Northeastern dish that is deeply loved by local people. The main ingredients are red bean paste, egg white, starch and sugar.

[0003] The existing method of preparing snow-covered bean paste is usually manual. First, the egg white is beaten and a small amount of starch is added. As the egg white is stirred, rich foam will gradually be produced. When the egg white is beaten to the extent that the chopsticks can stand up without falling, the snow coat (egg foam paste) is ready. Then the prepared bean paste filling is divided into small pieces of uniform size and kneaded into bean paste balls. Then a bean paste ball is picked up with chopsticks, put into the snow coat, and gently turned so that the bean paste is evenly coated with a thick layer of egg foam paste, just like putting a "snow coat" on the bean paste, to make a bean paste snow coat blank. Then the bean paste snow coat blank is put into the oil pan. During the frying process, the bean paste is constantly gently turned with chopsticks to make it evenly heated. As the oil temperature rises, the egg foam paste will slowly expand and turn white until it becomes a golden snow-covered bean paste semi-finished product, which can be fished out. The fried snow-covered bean paste semi-finished product is fished out, the oil is drained, and white sugar is sprinkled on it to make the snow-covered bean paste.

[0004] The step of making the bean paste snow coat blank is particularly important, which is the key to determining the appearance of the bean paste snow coat. The existing method of manually picking up the bean paste ball with chopsticks and putting it into the snow coat to rotate is poor in shaping effect, and it is impossible to prepare the bean paste snow coat with high ball degree, and the appearance is poor.

A plurality of guide channels 609 for guiding the bean paste balls 8 to enter are formed on the guide frame 602. The ends of the guide channels 609 are closed structures. The number of guide channels 609 is the same as the number of the lower hemisphere grooves 215. The guide channel 609 has a flared portion and a straight portion.

The conveyor 601 is a belt conveyor 601 of the prior art. By placing the bean paste ball 8 on the conveyor 601, the conveyor 601 conveys the bean paste ball 8. When the bean paste ball 8 moves to the guide frame 602, it automatically enters the guide channel 609, and enters the flaring part and the straight part in turn. When the bean paste ball 8 moves to the end of the straight part, the proximity switch 603 detects a signal. When all the proximity switches 603 detect a signal, there is a bean paste ball 8 at the end of each straight part, and then the conveyor 601 stops working; then, the third lifting linear actuator 606 drives the third lifting frame 607 and the flexible clamp 608 to descend, and the two clamping parts of the flexible clamp 608 enter the clamping port 610, and then the flexible clamp 608 works to clamp the bean paste ball 8 at the end of the straight part; then, the third lifting linear actuator 606 drives the third lifting frame 607 , the flexible clamp 608 rises, so that the flexible clamp 608 clamps the bean paste ball 8 and rises to above the guide frame 602; then the second horizontal linear actuator 604 drives the transverse frame 605, the third lifting linear actuator 606, and the flexible clamp 608 to move to above the transfer plate 51 below the unloading end of the conveyor 601. At this time, each bean paste ball 8 is located directly above the corresponding temporary storage through hole 59, and then the third lifting linear actuator 606 drives the flexible clamp 608 to descend, and the flexible clamp 608 releases the bean paste ball 8, so that the bean paste ball 8 falls into the temporary storage through hole 59; after the bean paste ball 8 at the end of the straight part is clamped away by the flexible clamp 608, the conveyor 601 continues to work until all proximity switches 603 detect signals, and the conveyor 601 stops working again.

[0026] The production process of snow-coated bean paste comprises the following steps: Step 1: Preparation of bean paste balls 8; Take small pieces of bean paste, knead them into balls and evenly coat them with a thin layer of starch to make bean paste balls 8; Place the bean paste balls 8 into the conveyor 601; Step 2: Preparation of snow coat; Beat the egg white at high speed until the egg white becomes fine, white, shiny and hard foamed, sift in the starch, stir evenly to make snow coat, add the snow coat to the snow coat storage bin 31; the ratio of the weight of the egg white to the weight of the sieved starch is 3:1; Step 3: shaping; when the upper mold 202, the shaping plate 208 and the lower mold 203 are stacked from top to bottom, the snow coat is injected into the feed port 213, and the snow coat passes through the first through hole 219, the connecting port 221 and the second through hole 220 in sequence, and then fills the lower hemispherical groove 215; the snow coat in the lower hemispherical groove 215 is in the shape of a hemispherical body with a concave top under the joint construction of the shaping plate 208, the small semicircular ball 218 and the lower hemispherical groove 215; then, the shaping plate 208 is transferred, and the bean paste ball 8 is placed in the concave part of the snow coat with a concave top; then, when the upper mold 202 and the lower mold 203 are stacked from top to bottom, the snow coat is injected into the feed port 213, and the snow coat fills the upper hemispherical groove 212, wraps the bean paste ball 8, and makes a spherical snow coat bean paste blank; Step 4: frying; after the upper mold 202 is separated from the lower mold 203, the lower mold 203 is driven to rotate above the fryer 4, and the snow-coated bean paste blank in the lower hemispherical groove 215 falls into the fryer 4 by gravity; during the frying process, oil is continuously poured on the snow-coated bean paste blank and / or the snow-coated bean paste blank is turned over to ensure that the snow-coated bean paste is evenly heated and finally fried into a semi-finished snow-coated bean paste; the time and oil temperature of the frying process are manually controlled, and the frying time and temperature of the prior art can be adopted; Step 5: Remove from the pan; take out the fried snow-coated bean paste semi-finished product, drain the excess oil and sprinkle with sugar while it is still hot to make the snow-coated bean paste.

[0027] Wherein, the ball diameter of bean paste ball 8 is 1-3 centimetres, and the ball diameter of snow-covered bean paste blank is 2-4 times of the ball diameter of bean paste ball 8. In the present embodiment, the ball diameter of bean paste ball 8 is 2 centimetres, and the ball diameter of snow-covered bean paste blank is 3 times of the ball diameter of bean paste ball 8.

[0028] The following is a detailed description of the process of steps three and four: 1. Such as Figure 1 , Figure 2 and Figure 3 As shown, when the transfer plate 51 rotates to a position below the unloading end of the conveyor 601, the bean paste conveying mechanism 6 works to convey the bean paste balls 8 to the temporary storage through hole 59 through the flexible clamping claws 608; 2. For example Figure 5 , Figure 6 , Figure 7 , Fig.11 As shown, the first rotating power source 207 drives the shaping plate 208 to rotate 180 degrees clockwise, so that the shaping plate 208 rotates to between the upper mold 202 and the lower mold 203. At this time, the lower mold 203 is directly below the upper mold 202; 3. Then, the first lifting linear actuator 201 and the second lifting linear actuator 205 work. The first lifting linear actuator 201 drives the upper mold 202, the first lifting frame 204, the second lifting linear actuator 205, the second lifting frame 206, the first rotary power source 207, and the shaping plate 208 to descend. The second lifting linear actuator 205 drives the second lifting frame 206, the first rotary power source 207, and the shaping plate 208 to move closer to the upper mold 202, so that the blocking member 217 enters the upper hemispherical groove 212 and closes the recovery port 214. Finally, the upper end surface of the shaping plate 208 is sealed and fitted with the lower end surface of the upper mold 202, and the lower end surface of the shaping plate 208 is sealed and fitted with the upper end surface of the lower mold 203. The feed port 213 is connected with the lower hemispherical groove 215 through the first through hole 219, the connecting port 221, and the second through hole 220 in sequence. 4. The snow coat supply pump 32 works to deliver the snow coat in the snow coat storage bin 31 to each feed port 213 through the snow coat supply pipe 34; the snow coat enters the lower hemispherical groove 215 through the feed port 213, the first through hole 219, the connecting port 221, and the second through hole 220, and the gas and excess snow coat are discharged from the overflow port 216; 5. After the snow coat is injected, the first lifting linear actuator 201 drives the upper mold 202, the first lifting frame 204, the second lifting linear actuator 205, the second lifting frame 206, the first rotary power source 207, and the shaping plate 208 to rise as a whole, and a hemispherical snow coat with a concave top is formed in the lower hemispherical groove 215; 6. The second lifting linear actuator 205 drives the second lifting frame 206, the first rotary power source 207, and the shaping plate 208 to descend, so that the blocking member 217 is away from the upper hemispherical groove 212; 7, such as Figure 8 , Fig. 9 , Fig.10 , Fig.12 As shown, the first rotary power source 207 drives the shaping plate 208 to rotate 90 degrees counterclockwise, so that the shaping plate 208 is no longer located between the upper mold 202 and the lower mold 203, and the transfer plate 51 rotates to between the upper mold 202 and the lower mold 203, and the temporary storage through hole 59 is located directly above the corresponding lower hemispherical groove 215; 8, the first horizontal linear actuator 58 pushes the push plate 55 to move, thereby driving the first guide rod 52 and the stopper 57 to move linearly, the compression spring 54 is compressed, the stopper 57 moves away from the temporary storage through hole 59, and no longer blocks the bean paste ball 8, and the bean paste ball 8 falls radially to the top concave part of the hemispherical snow coat with the concave top in the lower hemispherical groove 215; 9. The first rotating power source 207 drives the shaping plate 208 to rotate counterclockwise by 90 degrees, so that the transfer plate 51 rotates to a position below the unloading end of the conveyor 601, away from the lower mold 203 and the upper mold 202; 10. After the transfer plate 51 moves away from the lower die 203 and the upper die 202, the first lifting linear actuator 201 drives the upper die 202 to descend, so that the lower end surface of the upper die 202 is sealed and fitted with the upper end surface of the upper die 202, and the upper hemispherical groove 212 and the lower hemispherical groove 215 form a spherical space; the feed port 213 is connected with the upper hemispherical groove 212 and the lower hemispherical groove 215; 11. The snow coat supply pump 32 works to deliver the snow coat in the snow coat storage bin 31 to each feed port 213 through the snow coat supply pipe 34; the snow coat enters the upper hemispherical tank 212 through the feed port 213, and the gas and excess snow coat are discharged from the recovery port 214 to the snow coat recovery pipe 35; 12. After the snow coat is injected, the first lifting linear actuator 201 drives the upper mold 202 to rise, and the lower hemispherical groove 215 contains the spherical bean paste snow coat blank; 13. After the upper mold 202 rises and moves away from the lower mold 203, the snow coat recovery pump 33 is started. The snow coat recovery pump 33 works, and a negative pressure is formed in the recovery port 214 through the snow coat recovery pipe 35, so that the snow coat remaining in the recovery port 214 and the upper hemispherical groove 212 is recovered into the snow coat storage bin 31; at the same time, the scraper mechanism 7 works, and the telescopic end of the third horizontal linear actuator 71 contracts to drive the scraper 72 to move linearly, and the scraper 72 scrapes off the snow coat remaining at the bottom of the lower mold 203, and the snow coat falls into the snow coat storage bin 31 due to gravity; then, the telescopic end of the third horizontal linear actuator 71 extends to drive the scraper 72 to reset, so that the scraper 72 is located on the side of the overflow port 216 close to the fryer 4; 14, the output end of the second rotating power source 209 drives the rotating shaft 211, the rotating frame 210, and the lower mold 203 to rotate approximately 180 degrees, so that the lower mold 203 rotates to the top of the frying pot 4, and the snow-coated bean paste blank in the lower hemispherical groove 215 falls into the frying pot 4 due to gravity; 15. The output end of the second rotating power source 209 drives the rotating shaft 211, the rotating frame 210, and the lower mold 203 to reset, so that the lower mold 203 rotates again to be directly below the upper mold 202; 16. Repeat the above steps 1-15 to achieve automated production.
