Abstract

The invention discloses a food machinery corn thresher. Its structure includes: a feeding hopper, a frame, a shock absorber, a load-bearing seat, a discharging hopper and a bracket. To solve this problem with the spiked roller, the corn has a large instantaneous impact during threshing, and the number of impacts is very frequent, which will cause a large elastic force and shock force during the threshing process. The bouncing height increases the contact area with the spiked roller and prolongs the contact time, thereby increasing the amount of corn threshing and reducing the threshing loss. Secondly, the grinding wheel on the spiked roller is used to clean the cytoplasm of corn kernels during processing. The sand and dust embedded in the layers are formed by the dust collector to form a negative pressure environment to drive the powdery substances falling from the corn to gather and store them uniformly, preventing the dust from directly wafting out and causing pollution to the air and avoiding the generation of threshed corn. Secondary pollution.

Description

A food machinery corn thresher

technical field

The invention relates to the field of food processing machinery, in particular to a food machinery corn thresher.

Background technique

In the northern region, corn is a crop with a large planting area and high yield. The preservation technology of corn is very important. The existing technology usually removes part of the water after drying the corn on the ear field, and then threshing and then using a drying tower to dry the corn. Drying corn kernels reduces the moisture content of corn kernels to meet the preservation standards. Due to the high moisture content during threshing of corn ears, the strength of the connection between the kernels and the mandrel generally reduces the threshing quality and increases the threshing loss, and centralized drying in the ear field will cause dust to adhere to the surface. On the surface of corn ears, dust will be mixed in the cytoplasmic layer of corn kernels during threshing, which cannot be effectively cleaned when eating. For food-grade standards, the hygienic standards for agricultural machinery are not applicable to food-grade corn processing. The key is to remove the dust attached to the surface of the corn kernel and the impurities in the corn cytoplasmic layer. Based on the above premise, this case developed a food machinery corn thresher to solve this problem.
