Rotary feed crushing and drying device

Abstract

The invention discloses a rotary feed crushing and drying device including a machine body; a crushing screen cylinder is arranged in the machine body, a knocking device is arranged on the left side ofthe crushing screen cylinder, and a drying conical cylinder is arranged below the crushing screen cylinder. According to the rotary feed crushing and drying device, a crushing knife and a crushing screen cylinder with a periodic square rotation are used to fully smash and screen feed, thereby improving the efficiency of smashing and screening. The knocking device linkaged with a rotary shaft canknock the outer wall of the crushing screen cylinder, and the clogging of screen holes and the feed residues can be avoided. The drying conical cylinder with a cone structure and an annular stock guide are used to enable the feed to roll down uniformly on the surface of a drying screen cylinder, the feed is evenly dried, a spiral raised line is provided to increase the falling time of the feed, and the drying effect is ensured. According to an arc-shaped feed discharging scraper and a feed discharging pipe which is in tangential communication with the machine body, the feed discharging efficiency is increased, so that the feed discharging is more thorough.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a rotary feed crushing and drying device. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grain, sweet sorghum and more than ten varieties of feed materials. [0003] In the process of feed processing, multiple steps such as raw material cleaning, crushing, drying, batching, and granulation are usually required. Usually, these steps are completed by separate equipment, such as pulverizers and dryers, to crush and dry the feed. Dry, the feed needs to be transported back and forth, and the production efficiency needs to be improved; the crushing efficiency of the traditional pulverizer ...

Problems solved by technology

[0003] In the process of feed processing, multiple steps such as raw material cleaning, crushing, drying, batching, and granulation are usually required. Usually, these steps are completed by separate equipment, such as pulverizers and dryers, to crush and dry the feed. Dry, the feed needs to be transported back and forth, and the production efficiency needs to be improved; the crushing efficiency of the traditional pulverizer is low, and the screen and the inlet and outlet are prone to blockage; the traditional dryer uses the stirring mechanism to stir the feed, which cannot be done well. The feed is heated evenly, and the feed is easy to remain sticky in the drying drum, which is difficult to clean
