Description

Guide vane type low-pressure fixation machine and fixation method thereof

Technical Field

The invention relates to the field of tea fixation devices, in particular to a guide vane type low-pressure fixation machine and a fixation method thereof.

Background

Green tea is the most important tea in China at present, and occupies a more important position than other varieties in the tea making industry. The basic processing technology of the green tea comprises the following steps: spreading → deactivating enzyme → rolling → drying. The first process of primary processing of green tea is deactivation of enzymes, and the quality of the effect directly influences the processing of the green tea and the formation of the quality of the green tea. Deactivation of enzymes is a key process in green tea processing. The green removing is to adopt high temperature measures to emit moisture in the leaves, passivate the activity of enzyme and enable the content in the fresh leaves to generate certain chemical changes, thereby forming the quality characteristics of the green tea. Enzyme deactivation utilizes high temperature measures to inactivate enzyme activity and inhibit enzymatic reactions. Therefore, if the pot temperature is too low and the leaf temperature is too long in the enzyme deactivation process, the tea polyphenol can generate enzymatic reaction to generate red stems and red leaves. On the contrary, if the temperature is too high, the chlorophyll is damaged more, which leads to yellowing of the leaves, and some of them even generate scorched edges and spots, thus reducing the quality of green tea. At present, common water-removing equipment mainly comprises a pot type water-removing machine, a roller type water-removing machine, a steam type water-removing machine, a hot air type roller water-removing machine, a microwave water-removing machine and the like according to the water-removing principle and the structure type in the primary tea leaf making process.

The main factors influencing the quality of the enzyme-deactivating leaves include the equipment and technology adopted for enzyme-deactivating, the temperature controlled during enzyme-deactivating, the time of enzyme-deactivating, the leaf feeding amount at the tea inlet, the water content and the old and tender degree of fresh leaves and the like. Under the condition that the fixation equipment determines, the fixation temperature is the most main influence factor, and the over-low or over-high temperature can influence the fixation quality of the tea leaves, so that the control of the temperature in a proper range is the premise of ensuring the fixation quality.

The pot type green removing machine is a manual green removing machine, and the basic structure of the pot type green removing machine consists of a leaf frying pot, a leaf frying cavity, a hand frying device, a transmission mechanism and a furnace belly part. The pot type green removing machine has the advantages of simple structure, simple and convenient operation, fast leaf emergence, good green removing effect and lower price; but the continuous operation cannot be realized, the side leaves are easy to be burnt, the leaves are not completely removed, and the operation of personnel is needed during the leaf removal.

The basic structure of the roller type water-removing machine is composed of a cylinder body, a furnace chamber, a rack and a transmission mechanism, and most of the roller type water-removing machine is integrated with a machine and a stove. The drum-type green removing machine is a machine type which is applied traditionally, has good green removing quality and convenient operation, can be used by machine types with various specifications and sizes, is widely applied to processing various bulk green tea and famous green tea, is a main type used in the current production, and can be replaced by no green removing machine at present. But the roller fixation machine also has the defects that: 1. in the tea area with frequent power failure, the machine has no practical place. 2. The cost is high, the water-removing machine is not easy to popularize, the price of one water-removing machine is about ten thousand yuan, and the power consumption is high. 3. The middle part in the roller is not easy to clean and is easy to cause secondary pollution. 4. The weight of the fixation is not easy to control, the rotation speed is slow, and the fixation is easy to stick to a pan and stir; the rotating speed is high, and the water-removing is easy to be insufficient. 5. The requirements for site infrastructure are high. 6. Most of the drum-type fixation machines are of open structures, and energy consumption loss is large.

The microwave enzyme deactivating machine is tea enzyme deactivating equipment with a roller inside a microwave cavity as a main body, and has the water deactivating principle that water molecules in tea leaves are subjected to rapid friction heating through microwave energy to deactivate active oxidase in fresh tea leaves, so that water evaporated from the tea leaves is softened and conveniently kneaded, the color and luster of the tea leaves are maintained, and fishy grass smell of the tea leaves is volatilized in the enzyme deactivating process. The microwave enzyme deactivation has the following advantages: 1. the microwave energy is utilized to heat the tea leaves, so that the tea leaf fixation efficiency is improved, and the energy consumption is reduced; 2. the tea leaves after microwave enzyme deactivation can keep the color and luster unchanged for a long time, and the breakage rate is low; 3. the microwave enzyme deactivating machine occupies less land, is convenient to operate and saves labor force; 4. the tea leaves are in the roller, and the fixation quality and the fragrance are improved under the protection of water vapor. But the biggest disadvantage of microwave enzyme deactivation is high cost.
