Abstract

A grain-drying machine consists of a mill furnace (8) which generates hot air, a blower (13) which blows the hot air into a fluidized bed, a fluidized bed (10) in which the materials are heated to dry, a hoisting machine (11) which lifts the materials, a cooling tower (12) in which the materials are cooled, a waste material hoisting machine (9) which treats waste materials and a dustbin (7). The front end of the fluidized bed is provided with an adjustable baffle (1) which controls the material fluidization thickness during the material fluidization process and the bottom of the fluidized bed is provided with a fluidization supporting frame (2) which can adjust height. When the utility model is in use and the materials have different moistures, the material adjustable baffle can adjust the thickness of the materials on the fluidized bed to ensure the drying effect of the materials; meanwhile, the adjustment of a lifting device of the fluidized bed can change the flow speed of the materials on the fluidized bed so as to improve the drying effect.

Description

Foodstuff drying device

Technical field

The utility model relates to a kind of grain-drying equipment, particularly to flow-control and the current velocity controller of granular material in the fluidisation drying course, and the elevator charging, the improvement of the control device of the flow size of discharging.

Background technology

Present domestic cereal fluid bed since front end not baffled, the fluid bed punch-through takes place in material more easily, material more for a long time, drying materials is inhomogeneous.The fluid bed inclination angle is unadjustable in addition, has limited the raising of the production efficiency of fluid bed.Simultaneously, the control of fluidised bed material flow size is in the fluid bed internal regulation at present, is easy to generate the material clogging.

Summary of the invention

The utility model is not done change to the basic module formation of existing foodstuff drying device, just the structure of part assembly is improved.Specifically, a kind of foodstuff drying device, by the heating furnace (8) that produces hot blast, hot blast is blasted the blower fan (13) of fluid bed, material is subjected to the fluid bed (10) of heated drying therein, elevator (11) with the material lifting, the cooling tower that material cools off therein (12), waste material elevator (9) and the dustbin (7) of handling waste material constitute, the air outlet of heating furnace (8) is communicated with blower fan (13) and inserts fluid bed (10) air inlet, fluid bed (10) discharging opening links to each other with grain elevator (11), cooling tower (12) is positioned at grain elevator bottom, dustbin (7) is connected by refuse elevator (9) and fluid bed (10) air inlet top, it is provided with the adjustable baffle plate (1) that the goods fluid thickness of material in fluid mapper process is controlled at the fluid bed front end, in the fluid bed bottom fluid bed bracing frame (2) that can regulate height is set.

Import department at grain elevator (11) is provided with the control valve (4) of controlling the flow size, and the adjustable hyoplastron (3) of control material outlet flow velocity is set at discharge end.

The setting of fluidised bed material control device has realized flow (time of staying) and control fluid bed mounting inclination angle and the outlet ratio of control material on fluid bed, thereby increases the purpose of (or minimizing) material outlet flow velocity.The setting of the volume control device of elevator charging, discharging can be controlled the feed rate size, control material outlet flow velocity.Realized that respectively the elevator mass flow can be in harmonious proportion the fluidised bed material flow and can regulate, thereby made the use of two distinct devices reach coupling, reduced unnecessary energy resource consumption.

The wind wing (5) of blower fan (13) is short type.Adapted to blower fan and worked under 200 degree high temperature, its wind wing is designed to short type, guarantees that long-term work is indeformable, and mechanical transmission mechanism separates with volute of blower is heat insulation.

Radiating tube (6) on the cooling tower (12) is five jiaos of types, and heat exchange area is bigger, has increased the area that cold wind contacts with material, has improved radiating efficiency, has reduced cold and hot swap time.

The utility model when work, when the humidity of material not simultaneously, the material controllable register can be regulated the thickness of material on fluid bed, guarantees the drying effect of material; Simultaneously, the adjusting of fluid bed lowering or hoisting gear can change the flowing velocity of material on fluid bed, improves drying efficiency.The setting of elevator charging control valve can realize regulating arbitrarily feed rate, can guarantee reliably that the mass flow of fluid bed matches; The setting of hyoplastron is regulated in discharging, can improve discharging speed, has avoided the generation of elevator clogging, and the blower fan wind wing is designed to short type, can guarantee that it at high temperature works for a long time, and is indeformable.The pentagon radiating tube can increase cold and hot exchange area, reduces cold and hot swap time.
