Further, a kind of baking agricultural products drying equipment of the present utility model, described baking casing is assembled into a relative confined space by heat preserving and insulating material, the air exhauster that utilizes baking casing top to arrange, make to toast formation negative pressure in casing, for exhausting hydrofuge, and have in profit energy-conservation.

Further, a kind of baking agricultural products drying equipment of the present utility model, described heat release coiled pipe group is vertically parallel to each other to configure by two groups of identical shaped coiled pipes and forms, wherein the heat transfer medium of a group is carried from bottom to top, another is organized subtend from top to bottom and carries, with complementary heat transfer medium, after entering baking box, because causing temperature, heat release reduces gradually the problem of baking temperature inequality in the case causing.

During use, startup regulated variable hot water circulating pump and flow control valve, hand-operated valve etc., for regulating flow and the flow velocity of circulating hot water to regulate to realize temperature, meet the technique needs for the treatment of roasting baking agricultural products temperature, the quality of raising baked goods; By baking tray and treat that roasting agricultural product are positioned over direct baking in the interval grid of heat release coiled pipe group, improve baking efficiency.

A kind of baking agricultural products drying equipment of the present utility model, adopt atmospheric hot-water or steam as heat transfer carrier, be provided with the convenient heat supply temperature that regulates of variable hot water circulating pump and flow control valve, guarantee that it can overtemperature in baking dry run, with two groups in opposite directions the heat release coiled pipe group complementation of convection current with the baking temperature in balanced baking box, protect as much as possible its color, shape, stopped the drawbacks such as burned smoke blowing fire taste, guaranteed to be baked the quality of product; The solar energy of employing environmental protection, coal, firewood etc. are as heat energy source, cheap, are easy to obtain in rural area, and operating cost is low; By enclosed, force hot water cyclesystem to reclaim waste heat and the water resource after heat transfer completely, to realize environmental protection and energy saving; Adopt suction pressure hydrofuge technology, the moisture that makes to be baked in product easily evaporates discharge, has saved baking heat energy, meets the requirement of energy-conserving and environment-protective.

A kind of baking agricultural products drying equipment of the present utility model, adopts commercially available qualified solar water heater and the heat supply of atmospheric steam hot-water boiler, safe and reliable, the thermal efficiency is high, and operating cost is cheap, and can improve the baking quality of agricultural product, guarantee color, smell, taste and shape, thereby increase farmers' income.
