Description

A kind of peanut drying equipment

technical field

The utility model belongs to the technical field of grain drying machines, in particular to a drying equipment for peanuts.

Background technique

As a major oil crop, peanuts are planted all over the country, mainly distributed in Liaoning, Shandong, Hebei, Henan, Guangdong and Sichuan. At present, the mechanized drying technology of peanuts after harvest is still blank, and natural drying is still the main method, which is greatly affected by weather factors. After the peanuts are harvested, the water content is very high. If they are not dried in time, they will become moldy and rot. In recent years, with the rapid advancement of the mechanization of peanut harvesting and fruit picking, the coordination and balance between my country’s original peanut harvesting and drying in the production area has gradually been broken. It will become increasingly difficult to store moisture safely. At the same time, with the transfer of rural population resources and the rapid advancement of peanut harvesting mechanization, traditional drying methods have gradually been unable to meet the needs of timely drying of peanuts. Research and development of efficient, economical and high-quality peanut rapid drying technology and equipment that meet my country's current actual production needs has become an important task to be solved in the development of my country's peanut industry.

Restricted by factors such as peanut geometric size, particle weight, biological characteristics, etc., peanut hot air drying equipment mainly includes three types: rotary cylinder dryer, box dryer and on-site drying equipment, which are respectively suitable for small batches, small and medium batches, and large batches. Batches of peanuts are dried. The rotary drum dryer has a small processing capacity, and it is difficult to meet the demand for centralized drying of a large number of peanuts. After the traditional box dryer is dried, the moisture content of the peanuts at the bottom of the box is very different from that at the top of the box. Often, the peanuts at the bottom are overdried, while the peanuts at the top are not dried enough, which affects the quality of peanuts. If in the subsequent storage stage, The moisture in the peanut heap cannot be released slowly and evenly, and there is a greater risk of mildew. On-site drying is mainly composed of warehouses, heating and blowing devices, ventilation ducts, etc., but it is prone to the phenomenon that the lower layer is over-dried and the moisture has not dropped last time, resulting in serious uneven moisture distribution of peanuts, and even mildew in some places; secondly, When high-temperature gas enters the pipeline inside the dryer for drying, there will be a large temperature difference in the heat exchange process, and the moisture and impurities of the peanut itself will greatly corrode the pipeline in a high-temperature and humid environment, and pipes often appear. Corrosion and broken roads have a greater impact on the drying effect, and broken metal slag will also be mixed in peanuts to affect the quality.
