[0033] like Figure 1-9 As shown, an apple chip pressure difference puffing device is provided in the embodiment, comprising: a bottom plate 1, a puffing tank 6, a steam generator 11, a vacuum tank 12 and a drying tank 13, wherein the puffing tank 6, the steam generator 11, the vacuum tank 12 and the drying tank 13 are all fixedly connected to the top of the bottom plate 1, the top of the bottom plate 1 is symmetrically fixedly connected with a slide rail 4, and the top of the bottom plate 1 is fixedly connected with a tooth plate 5; a pushing component 2, the pushing component 2 is slidably connected to the outer surfaces of the two slide rails 4, and the pushing component 2 includes two sliders 201, the two sliders 201 A bracket 202 is fixedly connected between the tops, a driving shaft 211 is rotatably connected to the rear surface of the bracket 202, and a rotating plate 213 is fixedly connected to the end surface of the driving shaft 211; a material storage component 3, the number of material storage components 3 is set to two, the two material storage components 3 are symmetrically fixedly connected to the rear surface of the rotating plate 213, the material storage component 3 includes a sealing cover 301, a support 305 is fixedly connected to the bottom inner side of the sealing cover 301, a connecting plate 306 is arranged on the outer surface of the support 305, and a side frame 307 is fixedly connected to the outer surface of the connecting plate 306.

[0034] like Figure 1 and Figure 2As shown, the puffing tank 6 is connected to the vacuum tank 12 through the connecting valve, the output end of the steam generator 11 is connected to the puffing tank 6, and the output end of the steam generator 11 is connected to the vacuum tank 12. When the apple slices are subjected to pressure differential puffing processing, the steam generator 11, the puffing tank 6 and the vacuum tank 12 cooperate to process the apple slices. After the pretreated apple slices are fed into the puffing tank 6, the steam generator 11 transmits high-temperature and high-pressure steam to the puffing tank 6, so that the water inside the apple slices is continuously evaporated. As the pressure inside the puffing tank 6 continues to rise, the connecting valve between the puffing tank 6 and the vacuum tank 12 is subsequently opened, so that the pressure inside the puffing tank 6 is suddenly reduced, so that the water inside the apple slices is suddenly vaporized and flashed, and a strong steam pressure difference is generated, so that the cells and tissues of the apple slices are expanded to achieve the purpose of puffing, and the processing of the apple crisp slices is completed.

When the rotating plate 213 is turned over by the operation of the second motor 207, the rotating plate 213 rotates one hundred and eighty degrees to complete the position adjustment of the placement frame 318. When the rotating plate 213 rotates, it will drive the through-beam sensors 214 on both sides to rotate accordingly. After the through-beam sensor 214 rotates to the other side, the setting of the light receiver 215 can play a travel limit role on the rotation angle of the rotating plate 213. After the through-beam sensor 214 and the light receiver 215 on the other side are through-beamed, the second motor 207 can be controlled to stop running, thereby achieving the purpose of automatically controlling the start-up travel of the second motor 207 and improving the degree of automation of the equipment.

When the rotating plate 213 rotates, the third motor 320 is started to drive the third rotating shaft 321 to rotate. The rotation of the third rotating shaft 321 can drive the connecting plate 306 to follow the rotation. When the rotating plate 213 rotates, the setting of rotating the connecting plate 306 can make the side frame 307 always in the upper position, so that the placement frame 318 always maintains an upward position. At the same time, the support seat 310 provides support for the support shaft 309, so that the support shaft 309 can rotate freely.
