Tea leaf dry-roasting control method and device

Abstract

The invention discloses a tea leaf dry-roasting control method and device. The tea leaf dry-roasting control method comprises the steps that a three-phase power source provides working voltage for a control driving module through a circuit breaker; a power source voltage transformation module transforms the three-phase power source into a direct-current power source; the power source voltage transformation module provides working voltage for a control processing module, a clock module and a heating device; the heating device heats a furnace body; the clock detects the rotating time of a motor; the working status of the control driving module is controlled and processed; the motor is driven to rotate forwards and reversely, accelerate and decelerate. The tea leaf dry-roasting control device comprises the three-phase power source, the circuit breaker, the driving module, the clock module, the control processing module, the heating device and the motor. According to the tea leaf dry-roasting control method and device, tea leaves in a roller can be effectively rolled at different degrees, the tea leaves are prevented from being attached to the inner wall of the roller, the tea leaf dry-roasting effect is effectively improved, and the end product quality of the tea leaves dried through roasting is high.

Description

technical field [0001] The invention relates to tea processing technology, in particular to a tea drying control method and device. Background technique [0002] The drying process of tea leaves is one of the important processes in tea processing. At present, there are many types of tea frying and drying machines. Among them, the applicant submitted an invention application on July 5, 2013. The name is a tea frying and drying machine. The authorized announcement number is CN 203369338 U. , a temperature sensor, a servo motor, a speed change mechanism, a heating seat and a heating tube arranged in the heating seat, there are evenly distributed leaf turning plates on the inner wall of the drum, which can adjust the temperature for frying, and control the turning speed of the drum, obviously Improve the dry quality of tea leaves. However, the circular drum moves in a regular circle to make the tea leaves be thrown out at an equal centrifugal force rate, so that the tea leaves...

AI Technical Summary

Problems solved by technology

However, the circular drum moves in a regular circle to make the tea leaves be thrown out at an equal centrifugal force rate, so that the tea leaves will be reliably stuck to the inner wall of the drum to some extent, making it difficult to stir the tea leaves completely, and the dried tea leaves are dry. The temperature is not uniform, and it is easy to form agglomerates. Although it has turning leaves, the turning leaves do not solve the above problems. On the contrary, more tea leaves are blocked on the back of the turning leaves, which makes these tea leaves over-dried and damages the quality of the tea.

In addition, the speed change mechanism controls the speed of the drum, and the rotation speed of the drum changes. Although it has a certain effect on the frying of the tea leaves, there is still the same situation that the above-mentioned centrifugal force throws out the tea leaves, so that the tea leaves stick to the inner wall of the drum. The rotation speed change is still in one direction, it is difficult to achieve effective frying of tea leaves
