Machinery of tea microwave drying and sterilization equipment

Tea refers to the leaves and buds of trees. It generally refers to the leaves of evergreen shrubs that can be used to make tea, and the beverages made from these leaves, which are later extended to herbal tea made from flowers, leaves, seeds and roots of all plants, such as chrysanthemum tea. The most important process of tea production is to kill green tea.

Tea is rich in polyphenol oxidase. If the green is not killed, polyphenols will be oxidized and fermented under the action of enzymes, so that the tea will quickly lose its color and then spoil. At present, in the rapid development of industrialization, according to the current commonly used methods of killing green, mainly including drum-type killing, hot air killing, steam killing and new tea microwave drying sterilization equipment machinery.

Advantages of tea microwave drying and sterilization equipment machinery:

1. Fast heating speed: Microwave drying machine can directly heat both inside and outside of the tea, without preheating, it can be processed on start.

2. Heating uniformity: The tea drying and sterilizing machine uniformly irradiates the tea through the electromagnetic wave generated by the magnetron, heating both inside and outside at the same time, no coke leaves, coke edges, debris and so on.

3. Less loss of nutrients in tea: tea stays in the microwave oven for a short time, and does not need air and steam to conduct heat. Therefore, microwave tea drying and sterilization machinery and equipment can maximize the retention of nutrients in tea.

4. Sterilization and alcoholization have great effects: tea is often contaminated by secondary pollution in the process of picking and making. Microwave sterilization and alcoholization have the characteristics of sterilization and drying. Microwave is especially effective for summer and autumn tea in addition to bitterness and astringency. This alcoholization function can not be latently replaced by other machines.

5. Tea quality has been improved: the surface temperature of tea leaves is not high when microwave is used to kill green leaves, and there is no need to cool them by blowing when they emerge, so the green leaves change little, the color and lustre are green, the aroma loss is less, and the drying is even. At the same time, because of the rapid evaporation of water, it is easy to form porous, the product has good rehydration, and the content is easy to dissolve when tea is brewed.

Technical parameters of tea microwave drying and sterilization equipment machinery specialty:

Compared with the traditional pot-type and drum-type tea-killing equipment, the tea microwave drying equipment has the advantages of high speed, high efficiency and good effect. At the same time, microwave can also remove excess moisture from fresh leaves, which will become soft and plasticity after evaporation by hot gas. Moreover, tea green-killing drying machine can be widely used in tea, chrysanthemum, honeysuckle, flowers and other agricultural products for green-killing, and the effect of green-killing is remarkable.
