Abstract

The invention discloses medicinal material and food drying equipment, which comprises a hot-air system, a circulating system, a drying chamber and an electric control box, wherein the hot-air system comprises a fuel chamber and a combustion chamber, and a feeding opening is arranged between the fuel chamber and the combustion chamber; the circulating system comprises a hot-gas circulating system and a waste-gas circulating system, wherein the hot-gas circulating system comprises a circulating fan, hot-air pipes, a heat-discharging pipe and a gas-returning pipe; the combustion chamber is connected with one end of the circulating fan through the hot-air pipe, and the other end of the circulating fan is connected with the heat-discharging pipe in the drying chamber through the hot-air pipe; the waste-gas circulating system comprises a waste-gas hot-air pipe and an exhaust fan. Temperature in the drying chamber of the medicinal material and food drying equipment disclosed by the invention can be kept constant for a long time, so that influences on the properties of medicinal materials and food due to excessive temperature fluctuation are avoided; waste heat generated in the combustion chamber is fully utilized for circularly heating the drying chamber, so that energy sources are greatly saved.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a drying equipment for medicinal food. Background technique [0002] Drying of medicinal materials and food is to dehydrate them, and maintain their original ingredients, and maintain their medicinal properties or edible properties. Drying is to allow them to be preserved for a long time. There are usually mechanical methods, heating methods, and chemical adsorption methods to remove moisture. Commonly used medicinal materials and food processing mainly use heating methods, using hot air to heat and remove moisture through convective heat exchange. [0003] The air out of the drying chamber of the traditional medicinal material drying equipment becomes low-temperature, high-moisture waste gas that is directly discharged into the environment. The drying equipment with this structure consumes a lot of energy and the drying speed is slow. Most of the heat energy is carried away by t...
