Energy-saving and environmentally-friendly characteristic scented tea leaf processing device

Abstract

The present invention provides an energy-saving and environment-friendly characteristic scented tea leaf processing device. A manufacture technology for tea leaves is simple and smooth, overall designof the device is scientific, energy-saving and environmentally friendly, besides, the produced tea leaves have a characteristic scent, the processing device is highly automated, a precise temperature-controlled tea leaf steam enzyme-deactivating method is creatively provided, the tea leaves have advantages of emerald green color and luster, complete bud leaves, etc. after steam enzyme-deactivating, after the steam enzyme-deactivating, then the tea leaves are stir-fried to be dry, finally, the prepared product has characteristics of high fragrance, strong taste, etc., and besides, a defect that the tea leaves have fragrance with bitter and astringent plant smell is avoided. The two technologies commonly use a same heat source for heat supply, are high in utilization efficiency of heat energy and meet current low-carbon and energy-saving requirements; and temperatures, air pressures and time of the enzyme-deactivating can be precisely controlled, the temperatures and time of drying canbe precisely controlled, and the energy-saving and environment-friendly characteristic scented tea leaf processing device is uniform in the drying, improves fine processing levels of the tea leaves, greatly improves manufacture quality of the tea leaves, and improves mouthfeel and quality of the tea leaves.

Description

technical field [0001] The invention relates to a processing equipment for tea with characteristic fragrance, in particular to an energy-saving and environment-friendly processing equipment for tea with characteristic fragrance, which belongs to the technical field of tea processing equipment. Background technique [0002] Green tea is one of the main teas in China. It is a beverage made from the new leaves or buds of the tea tree without fermentation, through processes such as greening, shaping, and drying. The color of its finished product and the tea soup after brewing mostly preserve the green style of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce the damage of nicotine to smokers. Green tea is made without fermentation, which retains the natural substances of fresh leaves, and contains more nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins. These natural n...

AI Technical Summary

Problems solved by technology

[0005] One is that people have designed a lot of automated equipment for tea processing and production, such as greening machines, stripping machines, dryers, etc., but at this stage people still use these automated production equipment to complete separate process production with separate equipment. The entire tea production process still requires a lot of manual operations to transfer tea between various equipments, and still fails to maximize the advantages of automated production equipment. The production efficiency is low, the production process pollutes the environment heavily, and consumes a lot of energy. poor quality tea;

[0006] The 2nd, fixing is one of the most critical processes in tea processing, but the fixing equipment and fixing process of the prior art are not good, the effect of fixing and the quality of tea leaves are not good, and uneven fixing often occurs, and the tea leaves produce red stalks, red leaves, and yellow leaves. Stuffy or easy to produce scorched leaves and other phenomena, the aroma of the tea produced is green, which affects the quality of the product;

[0007] The third is that tea processing equipment consumes a lot of energy, which does not conform to the current production concept of energy conservation and environmental protection. The energy consumption in the process of frying and drying is relatively large, and energy waste is serious. The excess heat energy generated at this time is not used in the process of tea greening. The two processes supply heat separately, the utilization efficiency of heat energy is low, the loss of heat energy is large, and the production cost is high, which does not meet the current low-carbon and energy-saving requirements;

[0008] Fourth, the current tea processing generally uses wood-fired and coal-fired equipment to provide heat energy, which has serious environmental pollution, poor temperature control stability, low thermal efficiency, and high operating costs. It is difficult for ordinary small and medium-sized tea production enterprises to bear, and they are currently being eliminated. Heating mode, not due to continued use;

[0009] Fifth, the precise control ability of the equipment is poor, the temperature, air pressure and time of finishing cannot be precisely controlled, the temperature and time of drying cannot be precisely controlled, and the drying is uneven, which reduces the level of finishing of tea and greatly affects the quality of tea. Production quality, reducing the taste and quality of tea
