Efficient feed crushing and drying equipment

Abstract

The invention discloses efficient feed crushing and drying equipment. The equipment comprises a feeding hopper and a drying box; throwing plates are peripherally distributed on the inner wall of the drying box; an air heater communicates to the lower end of the left side of the drying box; a discharge pipe is arranged at the lower end of the right side of the drying box; and a valve is arranged in the discharge pipe. The equipment is provided with a crushing roller and a double-channel crushing cylinder for two-stage crushing of feeds to achieve high processing efficiency; the equipment is provided with a hot gas utilization device for efficiently using waste gas heat to improve the heat utilization; meanwhile, the bonding of the feeds in the crushing cylinder is prevented, so that the waste of raw materials is prevented; as a turntable and the throwing plates are provided for throwing the feeds into the air for hot gas drying; meanwhile, caked feed blocks are collided with the inner wall of the drying box for scattering through the turntable, so that the feed drying efficiency is improved, and the drying is more thorough; and through a scraper, the discharge is more thorough.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to high-efficiency feed crushing and drying equipment. Background technique [0002] In the process of feed processing, the feed needs to be crushed and dried. In the traditional processing plant, separate grinders and dryers are used for crushing and drying, and the feed needs to be transferred between the grinder and the dryer, which not only occupies a large area , the production is not continuous, and the processing cycle is long, which is suitable for large-scale feed processing, but not suitable for small-scale feed processing; the traditional feed drying method is through the drum type or stirring type drying device, through the drum turning Stir with the stirring roller to turn the feed. The turning efficiency is low, which makes the drying more uniform to a certain extent. It is necessary to set the roller long enough to dry the feed thoroughly. It occupies a large area and c...

[0002] In the process of feed processing, the feed needs to be crushed and dried. In the traditional processing plant, separate grinders and dryers are used for crushing and drying, and the feed needs to be transferred between the grinder and the dryer, which not only occupies a large area , the production is not continuous, and the processing cycle is long, which is suitable for large-scale feed processing, but not suitable for small-scale feed processing; the traditional feed drying method is through the drum type or stirring type drying device, through the drum turning Stir with the stirring roller to turn the feed. The turning efficiency is low, which makes the drying more uniform to a certain extent. It is necessary to set the roller long enough to dry the feed thoroughly. It occupies a large area and consumes a lot of energy. At the same time There is no treatment device for the plate agglomeration in the feed, so that the quality of the feed is not guaranteed; in addition, the feed is easy to stick to the inner wall, resulting in uneven local heating and incomplete discharge
