Description

Technical Field

[0001] The present invention relates to a technical equipment for enhancing the fragrance of tea, belonging to the technical field of primary processing machinery for agricultural products, and relates to a far-infrared intelligent tea fragrance enhancer. More specifically, it is an equipment that uses efficient far-infrared heating technology to improve the quality and taste of tea and remove the astringency of tea. Background Art

[0002] Fragrance enhancement is an important processing technology to effectively improve the flavor quality of tea, which can effectively solve problems such as low, dull, and aged tea aroma. Reasonable application of the fragrance enhancement process helps to enhance the aroma intensity of tea and transform and optimize the tea fragrance type. At present, the fragrance enhancement methods include fragrance enhancement by baking cage roasting, hot air fragrance enhancement, stir-frying fragrance enhancement, and far-infrared fragrance enhancement, etc. Different fragrance enhancement methods can obtain products of different qualities. Common production technologies for solving problems such as low, dull, and aged tea aroma. Production practice and existing research have proved that reasonable application of the fragrance enhancement process helps to enhance the aroma intensity of tea and transform and optimize the tea fragrance type. At present, the fragrance enhancers on the market have low automation, and most are in the "sealed" mode, with poor fragrance enhancement effects. Far-infrared fragrance enhancement is considered by the industry to be an important development direction for future fragrance enhancement operations due to its advantages such as short fragrance enhancement time, high production efficiency, good and stable product quality, and suitability for continuous processing.

[0003] The principle of the far-infrared tea fragrance enhancer is mainly based on the heating characteristics of far-infrared, which causes energy level transitions and strong vibrations inside the tea molecules, enhances the internal energy of the tea, promotes the increase in temperature, and thus enhances the temperature and aroma of the tea. This heating method has the characteristics of high efficiency, uniformity, and environmental protection, and is suitable for the production process of tea fragrance enhancement. Since the heating time is short, it will not damage the color, aroma, and taste of the tea. In addition, far-infrared acts on the inside of the tea, so it maintains the flavor of the tea, removes the astringency of the tea, and can be stored for a long time.

[0004] With the continuous improvement of consumers' requirements for the quality and taste of tea, as well as the subdivision and diversified development of the tea market, more advanced and flexible fragrance enhancement equipment is needed to meet the processing requirements of different types and grades of tea. High-quality tea is an important carrier of tea culture. By using advanced fragrance enhancers to improve the quality of tea, it helps to better inherit and carry forward the long tea culture of China and enable more people to understand and love Chinese tea. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of low automation of existing tea flavor enhancing machines, most of which are in the "sealed" mode, with poor tea flavor enhancing effect. After preliminary drying, the moisture content of tea leaves is generally below 10%. Due to the uneven thickness and thickness of the tea leaves, the moisture content on the surface and inside is inconsistent. By stir-frying and baking the tea leaves at a low temperature in the flavor enhancing machine, first, the dried tea leaves are fully revived, and the temperature on the surface and inside of the tea leaves is the same; second, the tea leaves become more compact and smooth during the stir-frying and baking process; third, the aroma is enhanced. The moisture content of the tea leaves processed by the flavor enhancing machine is consistent inside and outside, and its moisture content is below 6%. This flavor enhancing machine will adopt far-infrared heating technology and combine with an intelligent control system, which can accurately regulate parameters such as temperature, time, and rotation speed, realizing efficient tea flavor enhancement. Based on PLC program control, the power can be adjusted as needed, the rotation speed of the cylinder can be frequency-controlled, and the flavor enhancing time can be set as needed to suit the flavor enhancing operations of different types of tea. The far-infrared heating method can control the temperature accurately, moderately, and evenly, with low energy consumption, high thermal efficiency, environmental protection, and cleanliness. It can accurately adjust the flavor enhancing parameters according to different tea varieties and quality requirements, and produce high-quality tea products that meet market demands.

[0006] To achieve the purpose of the present invention, the technical solution adopted is:

The regulating fan (37) is turned on during the processing of old tea to send air to remove the musty smell of the old tea.

8. The far-infrared intelligent tea flavor enhancing machine according to claim 1, characterized in that, The transmission component (4) includes a roller (41), a push rod motor (42) and a gear motor (43), and is fixedly installed on the frame (1). The maximum load capacity of the push rod motor (42) is 8000N, the stroke is 50mm, and the speed is 7mm / s. The gear motor (43) drives the frying and baking drum (31) to rotate through a sprocket drive with a transmission ratio of 7:

1. The rated speed of the gear motor (43) is 1420r / min. The roller (41) is fixedly installed on the frame (1) and is used to support the frying and baking drum (31) to perform rotational motion. When discharging tea, the frying and baking drum (31) rotates in reverse, and the push rod motor (42) pushes up the frame (1) and tilts the frying and baking drum (31), and the tea quickly discharges through the gap of the baffle (33).

9. The far-infrared intelligent tea flavor enhancer according to claim 1, characterized in that The control system (5) includes a human-machine interface, a control device and a frequency conversion device. The central controller of the control device selects the S7-200 Smart ST30 type PLC; the human-machine interface is set as a touch screen, and the user can select the manual setting of the fragrance-enhancing parameter mode or the preset automatic fragrance-enhancing mode through the touch screen of the human-machine interface. The fragrance-enhancing parameters include the fragrance-enhancing time, the fragrance-enhancing rotation speed and the fragrance-enhancing temperature.

10. The far-infrared intelligent tea flavor enhancer according to claim 9, characterized in that, The frequency conversion device includes a load frequency converter, which is used to realize the automatic adjustment of the entire tea fragrance-enhancing machine. Its specific working process: The temperature sensor (35) collects the temperature signal of the frying and baking drum (31) in real time, and hands it over to the central controller to complete the digital-to-analog conversion of the temperature signal. Then, after decision-making by the central controller, the output power of the far-infrared heating tube (34) is adjusted through the load frequency converter, and finally the accurate control of the fragrance-enhancing temperature is realized; according to the fragrance-enhancing rotation speed set on the touch screen, through the PLC analog output function, the load frequency converter is controlled to automatically adjust the output frequency, so as to control the rotation speed of the gear motor (43) and realize the automatic adjustment of the fragrance-enhancing rotation speed.
