Multifunctional dryer

Abstract

The invention discloses a multifunctional dryer, which comprises a combustible gas supply device, a hot air chamber and an oven body. A combustion chamber and a heat dissipation pipeline are arranged in the hot air chamber, the top of the hot air chamber is provided with a first eddy fan for conveying outside air to the hot air chamber, and a hot air outlet is formed below the side wall of the hot air chamber. The heat dissipation pipeline is arranged below the first eddy fan, one end of the heat dissipation pipeline is communicated with the combustion chamber, and the other end of the heat dissipation pipeline is communicated with an exhaust pipe. A grid supporting plate for supporting an agricultural product, a cold air axial flow fan positioned between the grid supporting plate and the bottom of the oven body and a condensation plate positioned between the grid supporting plate and the top of the oven body are arranged in the oven body; the part, positioned between the grid supporting plate and the bottom of the oven body, of the side wall of the oven body is provided with a hot air inlet; and the top of the oven body is provided with a dehumidifying axial flow fan for conveying wet airflow in the oven body to the outside, and the top of the oven body is also provided with a hygrometer and a thermometer.

Description

Technical field: [0001] The invention relates to the technical field of agricultural product processing, in particular to a multifunctional dryer for drying agricultural products such as wolfberry, grapes, jujubes, melons, vegetables and the like. Background technique: [0002] At present, most of the units used for heating and drying agricultural and sideline products use steam drying or direct drying using conventional coal-fired furnaces, and what's more, the natural drying method is used to process agricultural and sideline products. The above-mentioned drying processing methods have the following defects: the cost of using steam units is high; when using conventional coal-fired furnaces to directly dry agricultural products, the conventional coal-fired furnaces are seriously polluted and the utilization rate of thermal efficiency is low, and the products obtained by drying cannot reach the food quality. Safety is guaranteed; the natural drying method is adopted, which t...

Problems solved by technology

The above-mentioned drying processing methods have the following defects: the cost of using steam units is high; when using conventional coal-fired furnaces to directly dry agricultural products, the conventional coal-fired furnaces are seriously polluted and the utilization rate of thermal efficiency is low, and the products obtained by drying cannot reach the food quality. Safety is guaranteed; the natural drying method is adopted, which takes up a lot of space, has low drying efficiency, and is limited by the weather, and the effect of drying is completely uncontrollable
