Introduction of Okara Dryer
Soybean pulp (also known as Okara or bean dregs) is a high-value by-product of soy milk and tofu production. Rich in dietary fiber, protein, and essential fats, dried Okara serves as a highly nutritious component for livestock feed. Based on the characteristics of soy bean pulp, we have designed a complete soy bean pulp drying system that can reduce the moisture content of bean dregs from 60% to around 12%. Following the drying and crushing processes, we can provide the packing machine. In addition, we can supply the complete pellet plant, by adding some auxiliary materials, converts the product into high-quality animal feed pellets. This drying system can also be used to dry soybean meal, pomace, spent grain, food waste,and other similar materials.
Advantages of Okara Dryer
01
Compact Footprint
Floor space is reduced by about 50% and investment by about 40% compared with a single rotary dryer.
02
Anti-Sticking & Anti-Scorching
A special breaking and lifting device inside the dryer effectively prevents material from sticking to the wall and scorching.
03
Deep-Processing Options
Follow-up sections such as crushing, mixing, granulating, baling and briquetting can be added to improve deep processing.
04
Precise Moisture Control
Material flow speed is controlled by frequency conversion, so the final moisture is easily controlled to meet your needs.
05
PLC Control System
The whole drying system uses centralized electrical control with high automation and easy operation.
06
Multiple Heat Sources
Coal, gas, oil, biomass particles, steam and other heat sources can be used.
Working Principle of Okara Dryer
After being dehydrated, the wet soy bean dregs enter the dryer, where they are evenly dispersed and fully contact the hot air as they are turned over by the uniformly distributed lifting plates in the drum. The dried product is then discharged through the discharge valve at the other end of the dryer.
During the drying process, the system fully accounts for the high moisture content, high protein content, and high viscosity of bean dregs, employing a unique lifting plate design and breaking device to ensure effective drying.
