Freeze Dried Cowpea

Dehydrated cowpeas are bright green in color and contain a large amount of protein, minerals, vitamins and dietary fiber. According to different production processes and product characteristics, dehydrated cowpeas can be divided into hot air dehydration products and vacuum freeze-dried products. Due to the huge investment of vacuum freeze-drying equipment and the high drying cost, it is not widely used in production. Domestic dehydrated cowpeas are mostly hot air dehydrated products. At present, dehydrated cowpea is mainly sold in large and medium-sized cities in China, and the important reason for restricting its export is the quality and safety of the product. With the attention of our government and the maturity of pollution-free production technology, the bottleneck problem is gradually being solved. DEHYDRATED VEGETABLES, as high value-added vegetable processing products, occupy an increasing proportion in my country's vegetable exports. Although the output of dehydrated vegetables in my country is increasing rapidly every year, accounting for a considerable share of the world's total output, according to industry estimates, the annual demand gap for dehydrated vegetables in both the international market and the domestic market is more than 50,000 tons. From the perspective of the domestic market, with the rapid economic development and the continuous improvement of people's living standards, the demand for dehydrated vegetables is gradually expanding, and the development prospects are very broad. Therefore, the development of dehydrated cowpea processing is a lucrative industry with more growth potential. The technical process of cowpea dehydration processing is: raw material harvesting → pretreatment (impurity removal, cleaning, de-heading, cutting, etc.) → blanching → cooling → dehydration → uniform moistening → secondary dehydration → post-processing (sorting, packaging, storage, etc.). Among them, the blanching and dehydration process is the key to the whole process, and it is the core to ensure the quality of dehydrated cowpea products.
