An auger lock for conveying particulate material there through, said auger lock includes an auger tube receiving particulate material therein including an auger section, a material plug section, and an exit section. In the auger section; a drive for rotating a rotatable spiral auger mounted concentrically on a rotatable drive shaft within said auger tube for conveying particulate material there through. In the material plug section; conveyed particulate material is allowed to accumulate and compact to form a material plug to minimize free flow of gases through said auger tube. In said exit section; a means for discharging said particulate material from said auger tube. Further including a spring for biasing said exit door into a closed position, wherein said exit door moveable between a exit door open position and a exit door closed position, wherein said closed position said exit door seals off an exit end of said auger tube preventing flow of material and gas through said exit end, and in said open position allowing flow of material through said exit end.
