Description

Technical Field

[0001] The utility model relates to the technical field of bread crumb crushing and drying, in particular to a bread crumb crushing and drying device. Background Art

[0002] Bread is a food made by grinding grains and heating them. It is made of wheat flour as the main raw material, yeast, eggs, oil, sugar, salt and other auxiliary materials, and water is added to make dough. It is processed through processes such as cutting, shaping, proofing, baking, and cooling. Bread has a short shelf life. Bread cannot be eaten after it expires. In addition, a large amount of bread crumbs will be produced during the processing of bread. The recycling method of expired bread and bread crumbs is mostly to dry and crush the bread and make it into fish feed for recycling.

[0003] When recycling bread crumbs and expired bread, two devices are usually used to first dry and then crush them, or first crush and then dry them, which is carried out in two steps, and the work efficiency is low. Although some existing devices (such as CN 214759056 U, a bread crumb crushing and drying device) have the functions of integrated drying and crushing, due to the short drying time, the bread crumbs often adhere to the crushing blade head during subsequent crushing due to the high moisture content, which affects the crushing effect and the control of the particle size. Therefore, it is necessary to design a corresponding technical solution to solve the existing technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a bread crumb crushing and drying device to solve the problems raised in the above background technology.

[0021] A material guide hopper 11 is installed in the box body 1 between the drying mechanism and the secondary crushing mechanism.

[0022] It is necessary to explain that the multiple ducts 7 are connected to the external drying jet assembly through the air pipe. This type of equipment is an existing modular assembly and this application does not provide a specific description of it.

[0023] Specifically, the shaking assembly includes multiple shaking units installed under the mesh plate 6, and the shaking unit includes a rotating shaft 12, a mounting plate 13 and a connecting rod 14. The rotating shaft 12 is rotatably installed in the box body 1, and multiple fixed plates are fixedly installed on the rotating shaft 12. The rotating shafts 12 in the multiple shaking units are connected through a synchronous belt pulley group 19. The side array of the fixed plate is fixedly provided with multiple connecting rods 14. The end of the connecting rod 14 is installed with a fixed ball 15. The rotation trajectory of the fixed ball 15 interferes with the flipping trajectory of the mesh plate 6.

[0024] In addition, when the bread crumbs enter the box body 1 through the feed hopper 2, in order to prevent large pieces of bread crumbs or bread crumbs stuck together from affecting the drying quality, a primary crushing mechanism is also installed in the feed hopper 2 in the present application, and the primary crushing mechanism includes crushing rollers 16 symmetrically rotatably installed in the feed hopper 2, and the two crushing rollers 16 are connected by a gear set. One of the crushing rollers 16 is driven by a motor 17 arranged on the box body 1. Specifically, the primary crushing mechanism can perform primary crushing on large pieces of bread crumbs and bread crumbs stuck together, so as to avoid the phenomenon that some large pieces of bread crumbs are not dried thoroughly.

[0025] Preferably, a transmission shaft 18 is rotatably mounted on the side of the box body 1, one end of the transmission shaft 18 is connected to one of the rotating shafts 12 through a bevel gear set 20, and the other end is connected to the crushing shaft 4 and one of the crushing rollers 16 through a pulley transmission set 21. The setting of the transmission shaft 18 and the pulley transmission set 21 only requires one motor 17 to drive the synchronous operation of the primary crushing mechanism, the magnetic pole crushing mechanism and the shaking assembly, which has the advantages of energy saving and emission reduction.

[0026] Specifically, when the motor 17 drives one of the crushing rollers 16 to rotate, the two crushing rollers 16 in the feed hopper 2 rotate relative to each other under the transmission of the gear group, and the transmission shaft 18 and the crushing shaft 4 rotate synchronously under the transmission of the pulley transmission group 21. The transmission shaft 18 can drive one of the rotating shafts 12 to rotate under the transmission of the bevel gear group 20, and realize the operation of one of the shaking units. In conjunction with the synchronous pulley group 19, the synchronous operation of the remaining shaking units can be realized.
