Present fruit and vegetable drying equipment normally adopts fire coal, oil firing or the electrothermal hot-air of heating to produce hot blast or electric direct-fired mode, after air under the normal temperature carried out coal combustion heating, oil firing heating or electrical heating, send into baking zone fruits and vegetables are dried.But because the particularity of Chinese yam material when adopting existing drying plant to toast Chinese yam, often is difficult to realize omnibearing baking, and because hot blast skewness, occur roasting paste the in Chinese yam top layer easily and the phenomenon of material center " roasting care ", and energy consumption is big, the cost height.
Conduction oil also claims organic heat carrier, because of energy-conservation, and thermal efficiency height, conduct heat evenly, and can accurately control temperature, be widely used in gradually in recent years building the road, in the industries such as chemical industry, weaving, food processing, as the indirect medium, but in fruit and vegetable drying equipment, do not see use as yet.
Summary of the invention
The objective of the invention is to remedy the defective that existing fruit and vegetable drying equipment baking is inhomogeneous, energy consumption is big, a kind of electric heating oil drying unit that agricultural byproducts such as fruits and vegetables especially are suitable for Chinese yam that is suitable for is provided.
Realize that the technical scheme that the object of the invention adopted is:
A kind of electric heating oil drying unit, at least comprise casing, the air-supply thermal treatment zone and the baking zone that is communicated with the air-supply thermal treatment zone, the air-supply thermal treatment zone is communicated with the thermal source district, the thermal source district comprises the temperature control box of splendid attire conduction oil at least, be fixed with the electric heating tube that is immersed in the conduction oil in the temperature control box, temperature control box top is provided with oil pressure gauge and temperature sensor; The air-supply thermal treatment zone comprises air-blast device, fin, circulation air port and cold wind import at least, air-blast device is positioned at the fin top, the circulation air port is positioned at the air-supply thermal treatment zone and baking zone connection place, the cold wind import is positioned at air-supply top, the thermal treatment zone and is communicated with atmosphere, and temperature control box, oil pump and fin are communicated with by oil pipe; Baking zone comprises drying baker at least and is positioned at the moisture exhausting port of drying baker top, is provided with material pallet and the carrier that is used to carry the material pallet in the drying baker, and the material pallet is netted, and carrier is provided with some air vents.
Described casing is provided with chamber door, and chamber door is provided with observation window.
Place, described circulation air port is provided with screen pack.
Described cold wind import department is provided with volume control damper.
Described carrier is provided with some tray slots that are used to carry the material pallet.
Described carrier is one secondary or more than the pair.
Electric heating oil drying unit of the present invention is with the heat-conducting oil heating air material to be dried, conduct heat evenly, avoided roasting paste the in material top layer and the situation of " bake and care ", heat exchanging process is the secondary closed cycle, effectively reduce the energy consumption of whole heating system, reduced entreprise cost.Can not produce dust or oil smoke during heating, realize non-pollution discharge.This apparatus structure is simple, is suitable for various production-scale needs, directly regulates high hot air flow simultaneously and has improved the production safety performance.
