[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] Example 1

[0032] A food high-temperature sterilization device comprises a feeding part, a position-changing part and a discharging part;

[0033] The specific structure of the transposition part is as follows:

[0034] like Figure 1 、 Figure 2 、 Figure 3 As shown, the material transmission assembly 1 is composed of two parallel chains 12. Both ends of the two chains 12 are adapted to be installed with sprockets 11. A mounting plate is provided on the outside of the chain 12. The sprockets 11 are rotatably connected to the mounting plate. A motor is mounted on the mounting surface. The output shaft of the motor is connected to two of the aligned sprockets 11. The motor is set to work intermittently through the controller to drive the chains 12 to conduct synchronously and intermittently.

[0035] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6、 Figure 7 As shown, there are several station assemblies 2 between the two chains 12. The station assemblies 2 are equidistantly distributed around the path of the chain 12. The station assemblies 2 include a barrel 21. The barrel 21 is a cylindrical barrel with a through top and a cylindrical chamber inside. Two sets of cross bars 24 are connected to the bottom of the barrel 21. The two ends of the two sets of cross bars 24 are respectively rotatably connected to the two chains 12, so that the barrel 21 is supported by the cross bars 24 and follows the chain 12. A cylindrical rubber barrel 22 is set inside the barrel 21. The top and bottom of the rubber barrel 22 are respectively sealed to the inner wall of the barrel 21, so that a closed air cavity is formed between the barrel 21 and the rubber barrel 22.

[0036] like Figure 6 、 Figure 7 、 Figure 8 As shown, a steam valve 8 is provided on the outside of each barrel 21, and the steam valve 8 includes a conduit 81, which is fixed to the outside of the barrel 21. The outer end of the conduit 81 is bent upward, and the conduit 81 is connected to the air cavity. A valve cavity 82 is provided inside the outer end of the conduit 81. The valve cavity 82 is small at the top and large at the bottom. The small end of the valve cavity 82 passes through the external environment. A frustum-shaped valve block 83 is provided in the valve cavity 82. The small end of the valve block 83 is adapted to the small end of the valve cavity 82, and the large end of the valve block 83 is smaller than the large end of the valve cavity 82. The valve block 83 is elastically connected to the inner wall of the valve cavity 82 through a spring.

[0037] The specific structure of the feeding part is as follows:

[0038] like Figure 1 、 Figure 2 As shown, the feeding conveyor belt 4 is placed on the upper part of the material transfer assembly 1, and one end of the feeding conveyor belt 4 is aligned with the end of the material transfer assembly 1. A funnel-shaped leakage tray 5 is set at this position, and the bottom of the leakage tray 5 is aligned with each barrel 21 passed by. This position is the loading station;

[0039] like Figure 1 、 Figure 2 、 Figure 4 As shown, a steam conveying device 3 is provided on the side of the material transfer component 1. The steam conveying device 3 is located downstream of the loading station. The steam conveying device 3 includes a steam generator 31 and a first cylinder 33. The first cylinder 33 is vertically fixed on the surface of the mounting plate of the material transfer component 1. A hard steam pipe 32 is fixedly connected to the telescopic end of the first cylinder 33. The bottom of the hard steam pipe 32 is connected to the steam output end of the steam generator 31 through a hose. The top of the steam pipe 32 is higher than the top of the barrel 21 and is bent downward by 180° so that the top of the steam pipe 32 is vertically aligned with the steam valve 8 passed through.

[0040] The specific structure of the discharge part is as follows:

[0041] like Figure 1 、 Figure 2 、 Figure 5As shown, the discharge conveyor belt 6 is placed at one end below the material transfer assembly 1. This position is the discharge station. An exhaust assembly 7 is set at the discharge station. The exhaust assembly 7 includes a second cylinder 71. The second cylinder 71 is vertically fixed to the mounting plate of the material transfer assembly 1. A touch rod 72 is fixed to the telescopic end of the second cylinder 71. The bottom of the touch rod 72 extends downward and then bends 180° upward, so that the bottom end of the touch rod 72 is vertically aligned with the steam valve 8 passed through.

[0042] The specific sterilization operations for food are as follows:

[0043] The feeding conveyor belt 4 and the discharging conveyor belt 6 are the transmission lines of the food assembly line. The food is sequentially introduced into the leakage tray 5 through the feeding conveyor belt 4. The chain 12 is driven by the motor to conduct intermittently, so that the station assembly 2 is aligned with the leakage tray 5 in turn, and the food falls into the rubber cylinder 22 in each barrel 21 in turn. The barrel 21 moves to the position of the steam conveying device 3, and the first cylinder 33 is contracted to make the steam pipe 32 descend. The top of the steam pipe 32 is closed with the conduit 81, and the steam generator 31 is used to increase the pressure to the steam pipe 32. Steam is delivered, and the steam applies pressure to the valve block 83, causing the valve block 83 to overcome the elastic force and move downward, thereby opening the valve cavity 82. The steam neatly enters the conduit 81 from the valve cavity 82 and then enters the air cavity. As the steam is filled, the air cavity gradually expands, and the rubber tube 22 gradually and tightly covers the outside of the food. The food is bound in the rubber tube 22, and the heat of the steam sterilizes the food. When the steam pipe 32 is out of contact with the conduit 81, the high-pressure steam in the air cavity acts on the valve block 83 to tightly plug the port of the valve cavity 82, thereby preventing steam leakage.

[0044] Each barrel 21 is filled with steam in turn to continuously sterilize each food independently at high temperature. The barrel 21 moves to the lower part following the chain 12, so that the barrel 21 forms an upside-down shape. When the barrel 21 moves to the discharge station, the heat of the steam is greatly reduced. At this time, the second cylinder 71 is opened and shortened, so that the touch rod 72 moves up to squeeze the valve block 83, and the valve cavity 82 is opened to release steam. At this time, the volume of the air cavity is reduced, and the rubber cylinder 22 gradually recovers, releasing the wrapping limit of the food. The food is discharged from the port of the barrel 21 and falls on the surface of the discharge conveyor belt 6.

[0045] like Figure 6 、 Figure 7 As shown, two displacement grooves 23 are opened at the bottom of the barrel 21, and cross bars 24 pass through the two displacement grooves 23 respectively. The barrel 21 is connected to the cross bars 24 through a spring. When the barrel 21 moves to the bending position following the chain 12, the distance between the two cross bars 24 will become smaller. The cross bars 24 overcome the elastic force and move in the displacement grooves 23, thereby changing the distance between the two cross bars 24, so that the barrel 21 can stably follow the chain 12 to conduct the movement.
