Okara, or soybean pulp, is a byproduct generated during the production of soy milk and tofu. Rich in dietary fiber, protein, and other nutrients, okara has traditionally been used as animal feed or discarded due to its high moisture content and perishable nature. However, with the increasing demand for sustainable food production and waste reduction, okara treatment has garnered attention, particularly the process of drying to extend its shelf life and usability. One of the most efficient methods for drying okara is through the use of an okara flash dryer.

  The okara flash dryer functions by rapidly removing moisture from okara through high-temperature air injection. During this process, okara is introduced into a drying chamber where it is immediately exposed to a flow of hot air. The high temperature, combined with the powerful airflow, causes rapid moisture evaporation, quickly reducing the moisture content to a stable level suitable for storage or further processing. This method is especially beneficial for high-moisture materials like okara, which can have water content exceeding 80%.

  The flash drying process has several advantages over traditional drying methods. First, it is time-efficient; flash drying completes the drying process in minutes, whereas conventional methods such as sun drying or oven drying can take several hours. This efficiency not only conserves energy but also minimizes the risk of microbial contamination, which is crucial given okara's susceptibility to spoilage. Second, flash drying preserves the nutritional quality of okara by minimizing nutrient loss. Dried bean dregs can be used to make animal feed, cat litter, etc., contributing to the circular economy.
