[0026] In the following, the concept, specific structure and technical effects of the present invention will be further described in conjunction with the accompanying drawings to fully understand the purpose, features and effects of the present invention.
[0027] Refer to figure 1 , 2 , 3, 4, 5, and 6, the present invention relates to an automated doughnut production equipment, which has an extrusion molding unit 1, a fermentation unit 2, a frying unit 3, an output unit 4, and a machine 架5. The extrusion molding unit 1, the fermentation unit 2, the frying unit 3, and the output unit 4 are integrated together through the frame 5. The extrusion molding unit 1 realizes the extrusion molding of the fabric into the doughnut body; the fermentation unit 2 receives the extrusion The forming unit 1 extrudes the formed doughnut embryo body, and provides a fermentation environment and time for the doughnut embryo body to ferment; the frying unit 3 receives the fermented doughnut embryo body output from the fermentation unit 2 and treats it The doughnut body is fried to form a doughnut product; while the frying unit 3 has the characteristics of turning the doughnut into noodles during frying the doughnut body; the output unit 4 will go through the frying unit 3 to fry The output of the formed donut. Realize the automatic continuous production of doughnut extrusion molding, fermentation and frying, thereby achieving precise quality control, from the molding weight to the frying temperature and frying time are all carefully controlled to ensure the perfect final product. Fully automatic continuous production, from forming, fermentation, frying to syrup pouring, all steps are carried out simultaneously, with high work efficiency, saving manpower and reducing production costs.
[0028] figure 1 , 2 , 3, 4, 5, and 6, in this embodiment, the fermentation unit 2 has a fermentation tray 21 distributed at intervals and a chain 22 that is connected in series to drive the rotation of the fermentation tray 21. The chain 22 is installed in conjunction with a sprocket 23, and the sprocket 23 Installed on the frame 5, the sprocket 23 rotates to drive the chain 22 to move; the fermentation tray 21 is hinged on the chain 22 according to a relatively rotatable suspension, so that the fermentation tray 21 lays flat under its own weight under normal conditions, which satisfies the extrusion molding unit 1. Place the doughnut embryos. The extrusion molding unit 1 of this embodiment is based on an air pressure extrusion operation. The extrusion molding unit 1 has an extrusion cavity 11 and a molding inner tube 12 arranged at the extrusion end of the extrusion cavity 11, a T forming head 13, and The cutter 14, the forming inner tube 12 is connected to the extrusion end of the extrusion cavity 11, the small end of the T forming head 13 is axially inserted into the forming inner tube 12 and fixed, and the big end of the T forming head 13 is connected to the forming inner The end of the tube 12 is left with an annular extrusion gap; the cutter 14 is tubular, and the cutter 14 is sleeved on the outer circumference of the inner tube 12; the cutter 14 expands and contracts along the axial direction of the inner tube 12, and the T forms the shape of the head 13 The outer diameter of the large end is consistent with the blade edge of the cutting knife 14, so that the cutting knife 14 and the T forming head 13 cooperate to cut, so that the extrusion molding unit 1 automatically forms the doughnut embryo body on the fermentation tray 21 of the fermentation unit 2. When working, the mixed fabric is added to the extrusion cavity 11 of the extrusion molding unit 1, and the fabric in the extrusion cavity 11 is moved to the extrusion end through inflation and pressure, and the molding inner tube 12, T is formed With the cooperation of the head 13 and the cutter 14, the doughnut embryo is automatically formed. When the cutter 14 cooperates with the T-forming head 13 for cutting, it temporarily seals the large end of the T-forming head 13 and the end of the inner tube 12 The annular extrusion gap left by the head fills the fabric in the inner tube 12 for re-extrusion. The doughnut embryo body is placed on the fermentation tray 21 to move with the chain 22 to obtain a suitable fermentation environment and time, with automatic fermentation, large flow rate and high work efficiency.
[0029] figure 1 , 2 , 3, 4, 5, and 6, in this embodiment, a transition conveyor 6 is provided between the fermentation unit 2 and the frying unit 3, and the fermentation tray 21 of the fermentation unit 2 moves above the transition conveyor 6. When the time is automatically overturned, the fermented doughnut embryos are unloaded on the transition conveyor 6, and the transition conveyor 6 transports the doughnuts to the frying unit 3. Further, the fermentation unit 2 is located above the transition conveyor 6 with a stop block 24, which stops the top of the fermentation tray 21 from the suspension arm of the chain 22, so that the fermentation tray 21 is connected to the chain 22. The hinge point is turned over, prompting the fermentation tray 21 to automatically flip over the transition conveyor 6 and unload the finished doughnut embryos on the transition conveyor 6. After the fermentation tray 21 is turned over, it will automatically return to its own weight flat state. Follow the chain 22 to move. The end of the transition conveyor belt 6 and the frying unit 3 is provided with a ramp 61. The doughnut embryo slides into the frying unit 3 through the ramp 61, so that the doughnut embryo enters the frying unit 3 smoothly and prevents Accidents such as oil splashing. The frying unit 3 has a frying container 31 and a pusher 32 and a flipper 33 arranged in the frying container 31. The pusher 32 is composed of a push chain and a horizontally arranged push rod. The push chain moves under the drive of a driving wheel. The pushing rod is fixed on the pushing chain to follow the pushing chain to move, so as to push the donuts in the frying container 31 to move, realizing continuous frying work. The tumbling device 33 flips through gaps, and the doughnuts are fried in a different face. The flipper 33 of this embodiment has a flip support shaft 331 and a flip plate 332 mounted on the flip support shaft. The flip plate 332 is provided with oil penetration holes to satisfy the requirement of turning up the donut while filtering out oil. The turning support shaft 331 is connected to the power source to provide turning power and automatically change the surface for frying. The output unit 4 has a crawler conveyor belt 41 and a horizontal conveyor belt 42; one end of the crawler conveyor belt 41 is inclined into the frying unit 3, so that the fried doughnuts in the frying unit 3 are taken out, and the crawler conveyor belt The other end of 41 is connected to the horizontal conveyor belt 42. In this embodiment, one end of the crawler conveyor belt 41 that is connected to the horizontal conveyor belt 42 is provided with a guide plate to make the doughnuts enter the horizontal conveyor belt 42 smoothly. The horizontal conveyor belt 42 is provided with syrup Station 43, this station can choose to pour syrup according to needs to increase the taste of donuts.
[0030] figure 1 , 2 , 3, 4, 5, and 6, in this embodiment, the extrusion molding unit 1 and the output unit 4 are separately placed on the left and right ends of the frame 5, and the chain 22 of the fermentation unit 2 is in the extrusion molding unit 1 and the output unit 4 are arranged in a roundabout way. The front and rear sides of the frame 5 are provided with movable doors 51; the frying unit 3 is located on the upper part of the frame 5 and is arranged close to the output unit 4. The overall structure is compact and the body is small, which is convenient for installation and use. Automatic control, speed can be adjusted according to the customer’s output requirements. The extrusion molding unit 1 can be designed with multiple extrusion heads to extrude multiple donuts onto the fermentation tray 21 of the fermentation unit 2. Of course, extrusion The molding unit 1 can also be designed with an extrusion head, and the extrusion molding unit 1 moves to realize the stepwise extrusion of multiple donuts onto the fermentation tray 21 of the fermentation unit 2. The specific scheme can be designed according to actual needs. The invention also has the characteristics of display production, so that customers can see the entire production process and increase their desire to buy.
