Fodder granulator

Abstract

A fodder granulator comprises a rack. Two horizontal blade rolls are adjacently arranged on the rack. A feeding hopper is arranged above the two blade rolls, and a receiving hopper is arranged below the two blade rolls. Each blade roll is composed of a cutter shaft and fan-shaped rotary vane type blades which are sleeved and overlapped together at intervals on the cutter shaft. Each rotary vane type blade on one blade roll is inserted to the spaces between the two corresponding rotary vane type blades on the other blade roll, so that the rotary vane type blades on the two cutter rolls are arranged in a staggered mode, and in the opposite rotating process, a granulation space is formed by the respective concave portions of the rotary vane type blades. The two ends of each blade roll are arranged on the rack through rotary shafts respectively, the ends of the rotary shafts at least on the same side of the two blade rolls are engaged with gear transmission mechanisms through fixed transmission gears respectively, one blade roll is a low-speed blade roll, and is in synchronous rotation connection with a large gear through one gear transmission mechanism, and the other blade roll is a high-speed blade roll and is in synchronous rotation connection with a small gear through the other gear transmission mechanism. The large gear and the small gear are engaged and connected with a motor through one gear shaft.

Description

technical field [0001] The invention relates to a feed granulator, which belongs to the technical field of aquaculture feed preparation. Background technique [0002] With the rapid development of the breeding industry, the demand for artificial feed is increasing, and people's requirements for the efficiency and quality of feed production are also getting higher and higher; [0003] In the production of feed, the granulation process is indispensable. The function of the existing granulator is not perfect, resulting in some defects. The stool will rub against the granulation ring, the extrusion granulation blade and the bottom plate to generate a lot of heat. If the material contains heat-sensitive materials, it will become sticky and block the mesh of the granulation ring, especially when the material contains When mixed with low-melting point materials, the low-melting point materials are easy to change after being heated, causing the low-melting point materials to decomp...

Problems solved by technology

[0003] In the production of feed, the granulation process is indispensable. The function of the existing granulator is not perfect, resulting in some defects. The stool will rub against the granulation ring, the extrusion granulation blade and the bottom plate to generate a lot of heat. If the material contains heat-sensitive materials, it will become sticky and block the mesh of the granulation ring, especially when the material contains When mixed with low-melting point materials, the low-melting point materials are easy to change after being heated, causing the low-melting point materials to decompose. Therefore, it is necessary to spray cooling gas into the hopper during the working process, but the feed pellets must be dried during packaging.
