[0002] The blanching machine is mainly used for blanching and deactivating enzymes of fruits, root vegetables, and fragile products such as carrots, asparagus, mushrooms, and fruit slices. It is an indispensable blanching device for pre-treatment processes such as quick-freezing, dehydration, and freeze-drying. It is a hot blanching treatment device often required in the color protection process of fruit and vegetable processing. After blanching, the activity of enzymes in fruits and vegetables is stopped to maintain the unique fresh color of fruits and vegetables, emit the green odor of vegetables and retain the fragrance, improve the softness of cells, facilitate water evaporation, and lay a good foundation for the technological requirements of the next drying and dehydration process.

[0003] However, there are also problems in the use of the blanching machine. After the food materials are blanched, a large amount of water will adhere to the surface of the food materials, which is not conducive to the next drying and dehydration process.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] Aiming at the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide a main shaft for a blanching machine to reduce the water adhered to the food materials after blanching.

[0008] A further technical solution thereof is that a radial screen is provided between adjacent circumferential screens, and the radial screen is arranged along the length direction of the shaft body.

[0009] A further technical solution thereof is that the support assembly includes support rods, the support rods are arranged along the circumferential direction of the shaft body, one end of the support rod is connected to the shaft body, and the other end of the support rod is connected to the circumferential screen.

[0010] A further technical solution is that the support assembly further includes a support plate which connects two layers of the circumferential screen simultaneously. There are two support plates which are respectively arranged on both width sides of the circumferential screen.

[0011] A further technical solution is that the support rod is made of round steel.

[0012] A further technical solution is that one end of the support rod close to the shaft body is bent to form a support section, and an acute angle is formed between the support section and the axis of the shaft body.

[0013] A further technical solution is that a rib plate is arranged between the circumferential screen and the support plate.

[0014] A further technical solution is that the shaft body is made of seamless pipe.

[0015] A further technical solution is that the end of the shaft body close to the circumferential screen in terms of length is a tail shaft, and a screw hole is formed in the tail shaft; the end of the shaft body far from the circumferential screen in terms of length is a head shaft, and a keyway is formed along the length direction on the head shaft.

[0016] A further technical solution is that the blade is a hollow blade.

[0017] The beneficial technical effects of the present utility model are as follows:

[0018] (1) For the main shaft of the blanching machine in the present utility model, a circumferential screen is arranged at one end of the shaft body in terms of length.

In addition, there are two layers of circumferential screens. While draining the water of the food materials, it can prevent foreign matters from the outside from entering and contaminating the food materials, playing a protective role for the food materials.

[0019] (2) Further, a radial screen is arranged between the two layers of circumferential screens. The radial screen connects the two layers of circumferential screens, and the water between the inner layer circumferential screens can flow along the radial screen to the outside. Thus, the water on the food materials can quickly flow away along the inner layer circumferential screen, the radial screen and the outer layer circumferential screen, shortening the residence time of the water on the inner layer circumferential screen and improving the draining efficiency of the food materials. At the same time, the radial screen can also support the inner layer screen and the outer layer screen to enhance the structural strength of the two layers of circumferential screens.

[0026] Figure 1 The front view structural schematic diagram of the main shaft for a blanching machine of the present utility model is shown. Please refer to Figure 1 The main shaft for a blanching machine includes a shaft body 2, blades 4, a circumferential screen 6 and a support assembly 5. The blades 4 are arranged on the shaft body 2, and the blades 4 are arranged spirally around the shaft body 2. When the shaft body 2 rotates, the spiral blades 4 can convey food materials along the shaft body 2. The circumferential screen 6 is arranged at one end of the length of the shaft body 2, and the circumferential screen 6 is arranged annularly along the circumferential direction of the shaft body 2. After the food materials are conveyed to the circumferential screen 6 part by the blades 4 on the shaft body 2, the water on the food materials can be drained through the circumferential screen 6, greatly reducing the water attached to the food materials and facilitating the subsequent drying and dehydration process. The support assembly 5 is connected to the shaft body 2, and the support assembly 5 supports the circumferential screen 6. Among them, two layers of circumferential screens 6 are provided, and the two layers of circumferential screens 6 are arranged annularly around the shaft body 2 with different diameters. While the two layers of circumferential screens 6 drain the water of the food materials, they can prevent foreign objects from the outside from passing through the circumferential screen 6 to contaminate the food materials, playing a protective role for the food materials.

[0027] Figure 2 The side view structural schematic diagram of the main shaft for the blanching machine of the present utility model is shown. Please refer to Figure 2 , a radial screen 7 is arranged between adjacent circumferential screens 6, and the radial screen 7 is arranged along the length direction of the shaft body 2. The radial screen 7 connects two layers of circumferential screens 6, and the moisture between the inner circumferential screens 6 can flow along the radial screen 7 to the outside. So that the moisture on the food ingredients can quickly flow away along the inner circumferential screen 6, the radial screen 7 and the outer circumferential screen 6, shortening the residence time of the moisture on the inner circumferential screen 6 and improving the draining efficiency of the food ingredients. At the same time, the radial screen 7 can also support the inner screen and the outer screen to enhance the structural strength of the two layers of circumferential screens 6.

[0028] Preferably, the circumferential screen 6 and the radial screen 7 can adopt punched mesh sheets. The punched mesh sheets are usually made of steel plates or other metal materials, having higher strength and durability, excellent physical and chemical properties. And the punched mesh sheets are lighter in weight, which is convenient for transportation and installation.

[0029] Please refer to Figure 1 and Figure 2 , the support assembly 5 includes a support rod 51, the support rod 51 is arranged along the circumferential direction of the shaft body 2, one end of the support rod 51 is connected to the shaft body 2, and the other end of the support rod 51 is connected to the circumferential screen 6. Wherein, the support rod 51 adopts round steel, and the arc surface of the round steel reduces the friction with the food ingredients, and the arc surface also reduces the damage of the round steel to the food ingredients.

[0030] Preferably, one end of the support rod 51 close to the shaft body 2 is bent to form a support section 511, and an acute angle is formed between the support section 511 and the axis of the shaft body 2. Specifically, the support section 511 is inclined towards the side where the food ingredients enter the circumferential screen 6. Because when the food ingredients are conveyed into the circumferential screen 6 by the blade 4, the food ingredients have a thrust on the circumferential screen 6. At this time, the inclined support section 511 can better conduct the thrust to the shaft body 2, and extend the service life of the support assembly 5.

[0031] Furthermore, the support assembly 5 further includes a support plate 52, the support plate 52 is connected to two layers of circumferential screens 6 at the same time, there are two support plates 52, and the two support plates 52 are respectively arranged on the width sides of the circumferential screen 6. The two support plates 52 and the two layers of circumferential screens 6 surround to form an annular space, and the support plate 52 hinders the lateral flow of moisture, restricts the moisture flowing through the inner circumferential screen 6 from flowing out along the outer circumferential screen 6 again, and prevents the moisture from flowing laterally back to the food ingredients.

[0032] Even further, a rib plate 53 is arranged between the circumferential screen 6 and the support plate 52. The rib plate 53 bears the vertical load and shear force of the support assembly 5. By arranging the rib plate 53, the bearing capacity of the support assembly 5 can be increased, and the strength and stiffness of the whole structure can be effectively enhanced.

[0033] Please refer toFigure 1 , the shaft body 2 is made of seamless pipe, and the blade 4 is a hollow blade 4, reducing the self-weight of the main shaft.

[0034] Preferably, the length end of the shaft body 2 close to the circumferential screen 6 is the tail shaft 3, and a threaded hole 31 is provided on the tail shaft 3. The length end of the shaft body 2 away from the circumferential screen 6 is the head shaft 1, and a keyway 11 is provided along the length direction on the head shaft 1. The main shaft is connected to the driving device and the shaft sleeve through the threaded hole 31 and the keyway 11.

[0035] The specific working process of the present utility model is as follows:

[0036] Set the main shaft in the blanching machine, and heat the blanching machine. Then convey the food materials into the blanching machine from the shaft head position and drive the main shaft to rotate. The rotating main shaft drives the blade 4 to rotate, and the spiral blade 4 rotates and drives the food materials to move along the shaft body 2 until the food materials move to the inner diameter of the circumferential screen 6. During this process, the food materials are continuously heated by the blanching machine. For the food materials that move to the inner diameter of the circumferential screen 6, the moisture on the food materials flows away along the inner circumferential screen 6, the radial screen 7 and the outer circumferential screen 6, and the food materials are drained.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
