Small circulating grain dryer is a kind of small grain dryer developed by our company based the continuous grain dryer. The circulating drying process of the machine solves the problem of small grain dryer that can't dry high-moisture raw grains due to the short time of drying. During operation of the machine, as raw grains fail to reach the safe-moisture level after dried for the first time, they will then be circulated into the dryer for the second drying with the circulating delivery system. The moisture level of grain will be tested in real time at the exit of dryer. Until the safe-moisture level of grain is reached, will the discharge valve be started to discharge the grain out of the dryer.

Small circulating grain dryer make use of the clean hot air as heat medium to dry grain. The interior of dryers is composed of angular ventilation boxes, which is arranged in a staggered arrangement. The angular boxes are filled with grains flowing downward. The hot air enters the intake angular box through the grain layer, and passes through the grain layer from above to below.

1. The circulating drying process extends the drying time without increasing height of the dryer, ensuring the drying effect on high-moisture raw grains, saving the cost and reducing the floor space.
2. The multi-layer horn box structure inside the dryer makes the exchange between grain layers and hot air more thoroughly and evenly.
3. The patented six-impeller grain discharge mode makes the grain discharge on the whole section of dryer more evenly and thoroughly.
4. The dryer is set multiple emergency grain discharge ports for easy maintenance and troubleshooting.
5. Coal or straw, wood and other biomass fuels are taken as fuels of hot blast stove. The combustion efficiency is high, significantly reducing the fuel cost.
6. Hand-fired hot blast stove and efficient steel tubular heat exchanger with the integrated structure of hot blast stove and heat exchanger are equipped. The hot blast stove is built overall, high in strength and durable.
7. On-line tester of grain moisture is equipped. The whole machine adopts one-touch intelligent automatic control and touch-screen operation interface, intuitive in display and easy to operate, and has manual control mode and automatic hot-blast temperature adjustment function.
