Dried sweet potato manufacturing machine with steam heating and temperature preserving mechanisms

Abstract

The present invention relates to a dried sweet potato manufacturing machine steam heating and temperature preserving mechanisms and belongs to the technical filed of the dried sweet potatoes. The manufacturing machine consists of a working table and a heating box body. A material outlet is arranged at the right side of the heating box body, two partition plates are arranged within the upper half of heating box body successively from left to right and divide the upper half of the heating box body into three heating zones with three different temperatures, steam cooling fins are arranged within each heating zone, the adjacent steam cooling fins are connected via pipelines, dispersion plates are arranged horizontally within the heating zones under each of the steam cooling fins, and three fans are arranged respectively above each of the steam cooling fins within the heating zones. A mixing tank is connected to the material outlet, a stirrer is arranged on the mixing tank, a steam jacket layer is arranged on the outside wall of the mixing tank, and baffle bars are spirally arranged on the inside wall of the mixing tank. By ensuring the advantages of the original design, the uniform mixing and temperature lowering effects of the dried sweet potatoes are accelerated, and at the same time, the machine is very conducive to large-scale production management.

Description

technical field [0001] The invention relates to a dried sweet potato processing device with a steam heating and heat preservation mechanism, belonging to the technical field of dried sweet potato processing. Background technique [0002] The sweet potato root contains 60%-80% water, 10%-30% starch, about 5% sugar and a small amount of protein, oil, cellulose, hemicellulose, pectin, ash, etc. If 2.5Kg fresh sweet potato Converted into 0.5Kg grain calculation, its nutrient components except fat, protein, carbohydrate and other content are all higher than rice, flour, and the protein composition in sweet potato is more reasonable, the essential amino acid content is high, especially the lycerum that is relatively lacking in grains and cereals. Amino acid has a higher content in sweet potatoes. In addition, sweet potato is rich in vitamins (carotene, vitamin A, B, C, E), and its starch is also easily absorbed by the body. [0003] There are many ways to make sweet potatoes. At...

Problems solved by technology

[0004] Last month, the inventor designed a set of dried sweet potato production equipment. Although the above-mentioned problems were solved in use, there are still shortcomings: if the dried sweet potato is unevenly dried, the main reason is that the specifications of the sweet potato strips are different, resulting in a drop in temperature. Inconsistency, it takes a lot of time to mix and cool sweet potatoes evenly after drying; at the same time, it will also be affected by the external temperature, making the cooling change from time to time, which is not conducive to large-scale production management
