Description

Efficient revolving bed drying machine

The utility model relates to a kind of efficient revolving bed drying machine, is used in a kind of drying machine that does not have pressure, convection type of fruit vegetable aspect specifically.

At present, known fruit and vegetable drier has two kinds of flow-through type and tunnel types.Flow-through type drying machine automaticity height, automatic charging, self-emptying, but use energy consumption big, invest also big.Moreover because the moisture content height of fruits and vegetables, often percolation does not once reach dry standard, needs twice, three times dryings, and productivity ratio is reduced, and the fruits and vegetables adhesive tape that the chance sugar is big is serious, needs manually be coated with clearly, has limited the use of this machine in garden stuff processing.The tunnel type drying equipment is a kind of original processing method, the material hothouse transfixion of packing into, and hot blast is prone to channel, and uneven drying is even, also need auxiliary equipment to carry out redrying, its energy consumption is big, and floor space is also big, construction investment is increased, and working power is dangerous, is difficult to reach technological requirement.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, and a kind of thermal energy conversion rate height that provides, obvious energy conservation, small investment, maintenance is easy to use, manipulation is simple, material rotates with revolving bed, makes the efficient atmospheric dryer of uniform drying.

The purpose of this utility model takes following measure to realize: this drying machine cuts the pallet of material and tray carriage, thermometer, electric cabinet etc. by cylindrical drying chamber, rectangle air-heater, dehumidification system, revolving bed, transmission mechanism, dress and forms.Wherein: cylindrical drying chamber is connected to form by circular arc sheet therebetween heat-insulation layer and following retainer plate, last retainer plate, the vertex of a cone; The rectangle air-heater is made up of exhaust blower, equal fan housing, heat exchanger, hot blast support; Arranging warm system is made up of side pump bowl, top outer cover, elbow, exhaust blower and homogenating plate; Revolving bed is made up of rotation bed surface, support, fixed axis, upper bearing (metal), lower bearing, lower supporter; The circular arc door is connected with the hothouse doorframe by hinge, on the circular arc door handle is housed, and visor is fastening through press strip, electric cabinet is contained in the hothouse outside, thermometer is contained on the hothouse arc plate, and pallet is inserted on the triangle tray carriage, pushes hothouse through the circular arc door and is installed on the rotation bed surface.

Cylindrical drying chamber is made by metal plate holder heat-insulation layer, and the rectangle air-heater is uprightly installed, and hot coal advances from the upper end, brings out down to form the heat power loop.During work, air is heated by air-heater and enters hothouse, at the hothouse opposite side dehumidification system is housed, during work, make hot-air form certain flow velocity, the material surface of flowing through carries out being discharged from after the wet exchange of heat, in order to make uniform drying, air-heater is the full-height air intake longitudinally, and to eliminate the thermograde of hothouse, the pallet and the tray carriage of loaded material rotate with revolving bed simultaneously, form the vertical hot blast of material transverse cuts, make the every bit of dry place can both thermally equivalent, form the rectangular space coordinate formula, realize evenly dry purpose.The lower surface of revolving bed is equipped with the annular friction track, and friction pulley is pressed on the friction track under the effect of spring, by motor through belt transmission, the decelerator transmission, chain is transferred to friction pulley, realizes the frictional drive of revolving bed.

During work, the startup of electric cabinet switch control air-heater, exhaust blower, revolving bed.The height of hothouse temperature is indicated by thermometer, and the thrust adjustable springs look nut of friction pulley and track is realized:

Tray carriage can freely advance, and pulls out hothouse, is convenient to maintain and replace, and pallet is manually placed by rotating revolving bed, extracts out, and the replacing of the dry material that wets is to reach the quantity-produced purpose.
