Quick and efficient betel nut drying system

Abstract

The invention discloses a quick and efficient betel nut drying system. The quick and efficient betel nut drying system comprises a refrigerant pipeline (1), a compressor (2), an air pipeline (3), a condenser (4), an expansion valve (5), a drying chamber (6), betel nuts (7), a fan (8) and an evaporator (9). The drying system is characterized in that the compressor (2), the condenser (4), the expansion valve (5) and the evaporator (9) are connected through refrigerant pipelines (1) respectively to form a refrigeration working circulation loop in which a refrigerant flows from the compressor (2)to the condenser (4), the expansion valve (5) to the evaporator (9) and then returns to the compressor (2); the betel nuts (7) are arranged in the drying chamber (6), the fan (8) is arranged on the side face of the evaporator (9), and the top of the drying chamber (6) is connected with the fan (8), the bottom of the drying chamber (6) is connected with the condenser (4) through the air pipeline (3) to form a drying loop from the fan (8) to the evaporator (9) to the condenser (4).

Description

technical field [0001] The invention relates to a fast and high-efficiency areca nut drying system, in particular to a betel nut drying technology which utilizes refrigeration to dehumidify and utilizes heat exchange to absorb energy, and relates to the technology of post-processing of betel nuts. Background technique [0002] At present, a large number of betel nut production enterprises still use the original earthen drying room to dry betel nuts in the betel nut drying process, but the production efficiency of this equipment is low, the labor force is large and the product hygiene cannot be guaranteed. The rough processing of betel nuts only stays in the way of smoking and roasting dried fruits in small workshops. The technology is backward and the product quality is difficult to guarantee. In addition, during the smoking process of betel nuts, a large amount of harmful gases are produced to pollute the environment. Although electric drying rooms are currently used to dry...

Problems solved by technology

[0002] At present, a large number of betel nut production enterprises still use the original earthen drying room to dry betel nuts in the betel nut drying process, but the production efficiency of this equipment is low, the labor force is large, and the product hygiene cannot be guaranteed.

Rough processing of betel nuts only stays in the way of smoking and roasting dried fruits in small workshops. The technology is backward and the product quality is difficult to guarantee

In addition, during the smoking process of betel nuts, a large amount of harmful gases are produced to pollute the environment. Although electric drying rooms are currently used to dry betel nuts, there are still problems in the placement of betel nuts in the drying room and the connection with hot air. more questions

[0003] There are also some that use electric energy and gas energy to heat and dry betel nuts, but the equipment is relatively complicated and the efficiency is not high, especially in the betel nut production areas, usually at the seaside, where the air humidity is very high, and the drying method of betel nuts is low in efficiency and high in energy consumption.
