Areca nut drying automatic temperature control moisture discharge system

Abstract

The invention discloses an areca nut drying automatic temperature control moisture discharge system which comprises a control unit. The control unit is respectively connected with a temperature and moisture sensor, a heat pump and a fan. Due to comprehensive utilization of the heat pump and the fan, temperature degree and moisture degree are controlled in a combined mode, so that stable and automatic control is maintained in the process of drying areca nuts. The temperature can be controlled to rise evenly in the drying process under normal temperature and ordinary pressure, the temperature in a drying box is even, dewatering speed is reasonably controlled and therefore core contracting degree and drying degree are precisely controlled. In the meantime, the system can achieve control over processing process so that the system can flexibly adapt to different geographical environments. Processing in an optimal mode can be conducted aiming at different types of the areca nuts, so that core contracting shapes of the areca nuts are better and taste of the areca nuts is guaranteed. The areca nut drying automatic temperature control moisture discharge system can be widely used in the field of food processing.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an automatic temperature-controlling and dehumidifying system for drying betel nuts. Background technique [0002] Explanation of terms: [0003] Shuxin refers to the firmness of the betel nut shell shrinking into a long and thin shape after being dried. Generally, the higher the degree of hardening, the better the appearance of the dried fruit, and the correspondingly higher price. [0004] Dryness refers to the degree of dryness of betel nut after being dried. The lower the water content, the higher the dryness. Usually farmers use the original weight of dried fruit per unit to indicate the degree of dryness. For example, if the dryness is 4.2 catties, it means that 4.2 catties of green fruit is dried to 1 catties of dried fruit. [0005] 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...

AI Technical Summary

Problems solved by technology

[0005] 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, in the betel nut smoking process, a large amount of harmful gas is produced to pollute the environment

[0006] However, in the large-scale betel nut drying system in the prior art, the drying system does not jointly control the temperature and humidity in the drying process, and requires personnel to be on duty during the drying process, which cannot realize automatic and flexible control of the drying process, and cannot Effective control and utilization of the drying temperature and humidity can easily lead to burnt betel nuts due to high temperature, or moldy betel nuts due to low humidity and high humidity; at the same time, humidity is also related to the quality and taste of dried betel nuts. The traditional betel nut drying technology completely relies on human experience to judge, so it is impossible to accurately control the quality and taste of the dried betel nut according to the specific environment
