Description

Technical Field

[0001] The utility model relates to a sweet potato residue feed machine, belonging to the technical field of sweet potato processing. Background Art

[0002] Using sweet potatoes as raw materials to make sweet potato starch or vermicelli will produce a lot of sweet potato residue. As an agricultural and sideline product, most of the sweet potato residue is regarded as waste. If the sweet potato residue is directly discarded without treatment, it will have a great impact on the environment; if it is transported as garbage and then processed in a centralized manner, there are disadvantages such as large transportation volume and high processing costs, resulting in a waste of resources.

[0003] Since the sweet potato residue contains cellulose, incompletely extracted starch, protein, calcium, phosphorus, etc., the sweet potato residue is prepared into feed together with straw and other nutritional additives in the prior art to improve the utilization rate of the sweet potato residue.

[0004] However, the water content of sweet potato residue is relatively high. When it is directly pressed into feed pellets together with other raw materials, it will stick together during the pelleting process, forming lumps or clogging the mold holes, resulting in poor pellet feed formation. In addition, when making pellet feed, each liquid additive is added to the sweet potato residue separately and then stirred, which can easily lead to uneven mixing and affect the pellet feed formation, resulting in unstable product quality. Utility Model Content

[0005] The utility model provides a sweet potato residue feed machine, which is designed to solve the technical problem that the feed machine in the prior art has poor molding when producing granular feed using sweet potato residue as raw material.

[0031] The working process of this utility model:

[0032] 1. The sweet potato residue enters the dehydration cylinder 102 from the feed port 101. After the first motor 104 is started, the spiral blade 1061 on the rotating shaft 106 is driven to rotate, pushing the sweet potato residue to move toward the outlet end of the dehydration cylinder 102.
