Grain dryers

Combustion gases of the heating medium are not directly involved in the drying process.
Grain dryer NS 8000 is designed for hygienically defect-free drying of products entering the foodstuff market. The grain dryer has an all-metal three-layer jacketed body, which is enclosed by a machine room from the front fans on the face of the backside. The three-layered jacket is modular and its length (6, 8, 10 and 12 m) directly affects the dryer output. These three jackets define four spaces. The first jacket delineates the heating area in which combustion gases from natural gas circulate. This heating system works under underpressure and is hermetically sealed from the other space the space between the first and second jackets which is the space for the heat exchanger, where the waste vapour mixture is heated and distributed to the vent holes of the second jacket. It enters the space of the third jacket here the space of the dried product. The third jacket is a stainless-steel mesh enabling the outflow of moist air into the surrounding area thus into the space of the fourth jacket. Drying takes place continually. The output of the dryer is given by the aforementioned type of dryer (body length), the drying temperature and the required percent of moisture removal. The dry product must be a loose and non-sticky material. The dryer is primarily intended for drying grain, corn and rape. The temperature in the dryer heating system ranges according to the type of dried product and the size of the temperature gradient from 160 to 360
