TH20100A - Machine and method for fluidized bed grain drying - Google Patents

Abstract

Fluidized bed grain dryer, which is used for continuous drying of high moisture grains in a short time. The machine components include combustion chamber (9), hot air blower (3), hot air volume control chamber (16), hot air chamber (17), grain feeder (10), feed unit. Grain grain removed (11), drying chamber (1), hot air recycle tube. (12), grain and dust extraction tube (4) and the separation cyclone (6) and the drying method, it consists of the process of feeding the seeds into the drying room using the grains feeder. Crop inlet (10) is a regulator of the flow rate of grain into the drying chamber. The process of blowing hot air from the combustion chamber (9) By a hot fan (3) through the air volume control chamber (16) to adjust the amount of hot air by the lever (21) before passing through the chamber, hot air path into the drying chamber, mix with the grain. The plant causes the moisture of the grain to be evaporated from the grain from the drying chamber through the suction ducts and dust (4) along with the withered seed and dust as well as some hot air leaving the room. Drying (1) The process of removing the dried cereal from the drying room (1) uses a grain feeder (11) to control the feed rate of the grain. From the drying chamber (1) The process of separating the impregnated grains and dust from the drying room due to the deflated seed and dust, when the moisture evaporates, it becomes light and floats in the suction pipe for the impurities and dirt (4). And the last step is conduction of hot air from the cyclone separating (6) leaving the oven The hot air is reused by the hot air that flows through the recycle pipe (12) to the combustion chamber (9) Mixed with air from the environment, it is sucked into the combustion chamber through the opening (14).

Claims (2)

1. Grain dryer Fluidized bed type It consists of a drying chamber (1), one wall fitted with clear fire-resistant glass (8), the bottom wall is a grate floor (19), one upper corner is equipped with a grain feeder (10). One is equipped with a grain feeder (11) and a baffle (5) installed in the cover (23) controls the flow of grain. Before going out into the feed unit (11), on the bottom wall of the drying chamber (1), connect it to the hot air chamber (17), which consists of a number of air baffles (22) below the hot air chamber. (17) connected to the hot air volume control room (16) which the inside of the hot air volume control chamber (16) consists of a hot air volume adjustment pad (20) is a flat sheet connected to the hot air volume control lever (21) which Sticking out In the upper wall of the chamber (1), make an outlet for the seed and dust (18), connect it to the extraction tube and dust (4) into the sorting cyclone (6), below the sorting cyclone ( 6) There will be a discharge hose for both dust and grains (13), and the top of the separator cyclone (6) will be connected to the hot air recycle tube (12) which is connected to the combustion chamber (9). And one end of the combustion chamber (9) Connect to the fan (3) before blowing air into the room to control the amount of hot air (16) 2. Fluidized Bed Grain Drying Method Which has the characteristics of continuous grain drying By continuously feeding into the drying chamber Hot air drying the grain The grain is blown perpendicular to the movement of the grain in the drying chamber and the grain is blown with hot air. Mix until the moisture drops. The kernels with reduced moisture, weight loss, were blown, pushed to a high altitude and moved to the end of the drying chamber. And skip the baffle out of the drying chamber The loose grains and very lightweight dust are sucked into the cyclone. Sorted and drained The hot air used is recycled. Through pipes to bring hot air back to use
