Kudzu section drying device

Abstract

The invention relates to the field of kudzu processing, in particular to a kudzu section drying device. The kudzu section drying device comprises an outer casing, a bin, a heating pipeline and a circulating air pipe. The kudzu section drying device is characterized in that the external wall of the heating pipeline is arranged on the internal wall of the outer casing through a thermal insulating layer; the lateral side of the outer casing is provided with a feeding sealing door and a discharging sealing door; the bin is in a cylindrical shape; the bin is connected to two ends of the heating pipeline through a rotary shaft; a travelling wheel is arranged between the bin and the rotary shaft; the travelling wheel is driven by a stepping motor; the circulating air pipe comprises an air outlet end and an air inlet end; two ends of the circulating air pipe are respectively connected to two ends of the outer casing; a condenser, a steam-water separator and a fan are in series connection to the circulating air pipe. The kudzu section drying device has the advantage of effectively solving the problem that a kudzu section is easy to gelatinize caused by high-temperature drying originally due to three-section drying.

Description

technical field [0001] The invention belongs to the field of kudzu root processing, in particular to a drying device for kudzu root slices. Background technique [0002] Pueraria lobata is a subtropical crop with high starch content and is easy to grow. Pueraria lobata is the root tuber of the leguminous plant Pueraria mirifica or Gange vine. It is a common vegetable in some provinces and regions in southern China. It tastes sweet and cool and is often used as a soup It can also be used as medicine. Wild kudzu root contains 12% flavonoids, such as puerarin, daidzein, peanut and other nutrients, as well as protein, amino acid, sugar, and minerals such as iron, calcium, copper and selenium necessary for the human body. It is a valuable tonic suitable for all, and has the reputation of "thousand-year ginseng". Picked fresh kudzu root still has a lot of water. After harvesting, it must be processed immediately or stored in an appropriate way, otherwise it will easily go bad. A...

Problems solved by technology

In response to this problem, people have adopted some kudzu root drying equipment for kudzu root slices, and the commonly used drying equipment uses heat to dry. Large, in order to achieve fast drying, generally the temperature is adjusted higher, which will easily cause gelatinization reaction on the surface of kudzu root, hydrolysis of starch, thus reducing the nutritional content of kudzu root slices
