Abstract

The invention discloses a novel Fuzhuan tea processing method. The novel Fuzhuan tea processing method comprises the followings step: grading and matching prepared primary tea; sterilizing the graded and matched tea by using high-temperature steam; appropriately compressing the sterilized tea by using a special mold; and strictly controlling necessary conditions for mildewing the Fuzhuan tea, including temperature and moisture change rates and the like, so that the Fuzhuan tea of excellent quality is prepared. The Fuzhuan tea prepared by the processing method has the following advantages: compared with Fuzhuan tea prepared by traditional methods, the Fuzhuan tea prepared by the processing method is better in quality, abundant in golden mildews and large in golden-mildew granular sizes; tea soup brewed from the Fuzhuan tea is red and bright in color, mellow in taste and rich in aroma; and the processing method is high in production efficiency.

Description

A kind of novel Fu-brick tea processing method

Technical field

The present invention relates to postfermented tea compressed tea manufacture field, the innovative machining method of a kind of Fu-brick tea.

Background technology

Fu-brick tea manufacture has more than 300 years history, originates in Jingyang, Shaanxi, is pressed into bricked through building, and ancient times must build system, drug effect such as Rhizoma Smilacis Glabrae on the hot summer days, therefore claims Fu-brick tea.Fu-brick tea is orange with soup color, glow, and fragrance is pure, flavour spy's Fu alcohol and, general Fu is pure famous.The ground such as stub Xinjiang, Qinghai, Gansu, Ningxia, are the important border-sale teas of China, are also beverages indispensable in the ethnic groups life of border area.

Nowadays along with process technology and the progress of equipment, the making of Fu-brick tea has been not limited to the hot summer days, and yield builds technology processed compared to ancient method Fu-brick tea huge lifting.Sporinite as key element " JINHUA " the i.e. Eurotium cristatum of Fu-brick tea flavour, fragrance and medical value, Fu-brick tea production process produces through " growing dim " this specific step, the product that the Fu-brick tea processing method of now is produced, generally there is the problems such as JINHUA quantity is few, JINHUA volume is little, it is uneven to grow dim, the different batches product situation of growing dim differs, difficulty of growing dim control, cause Fu-brick tea quality by strong influence；And current Fu-brick tea universal production technology production cycle is longer, causes production cost to be difficult to reduce.

Original Fu-brick tea production technology is optimized and innovates for the problems referred to above of the existence in current Fu-brick tea production process by this method, start a kind of brand-new Fu-brick tea process technology, by the processing method improveing raw tea raw material, optimizing all Alternatives such as wet heap, compacting, hot steaming, be finally obtained and grow dim uniformly, JINHUA is luxuriant, best in quality, stable Fu-brick tea product, and with short production cycle, yield is high, good in economic efficiency.

Summary of the invention

The invention reside in the deficiency overcoming original Fu-brick tea process technology, start a kind of brand-new Fu-brick tea process technology, finally give best in quality, stable, the Fu-brick tea product that JINHUA is luxuriant.

For realizing object above, the present invention is realized by techniques below means.

1. by fresh tea leaf after appropriateness is withered, fully knead, dry and make solar dried green tea, warehouse-in ageing.

2. solar dried green tea is after depositing, through sorting, assorted, high pressure steaming sterilizing, the most wet heap.

Raw tea regulation and control moisture content after the most wet heap, quantitatively, heat is steamed.

Be pressed into brick tea with certain pressure intensity the most subsequently, shaped after enter workshop of growing dim.

5. after brick tea being put neatly with the spacing of appropriateness in workshop of growing dim, strict temperature control, humidity and humiture rate of change, complete, through certain time, step of growing dim.

6. the brick tea process after growing dim persists, is dried link, warehouse-in ageing, detects, packs, dispatches from the factory after factory calibration to be achieved.

Accompanying drawing explanation

Fig. 1 is the process chart of the present invention.

Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, the present invention is expanded on further.

1., by fresh tea withering, after kneading, dry and make solar dried green tea.

2. solar dried green tea is suitably deposited depositing in the storehouse of water-proofing treatment, monitor closely humiture simultaneously.

3. be divided into some grades through the raw tea deposited according to indexs such as the quality of raw tea, leaf, the places of production, assorted after as the raw material of dissimilar Fu-brick tea product.

Measure the moisture content of every a collection of raw tea raw material the most respectively, and regulate and control raw tea moisture content at moderate temperatures to the suitableeest scope.

5. the raw tea regulating and controlling moisture content is steamed through High Temperature High Pressure.

6. the raw tea raw material after steaming suitably turns over even during putting into wet heap pond, abundant wet heap, wet heap.

After the most wet heap, raw tea is measured moisture content, is weighed, and is pressed into brick, puts into, after brick tea is shaped, workshop of growing dim after heat is steamed.

8. strictly control humiture after workshop of growing dim put into by brick tea, through certain time, allow brick tea fully grow dim.

9. after growing dim, brick tea is through persisting, putting ageing after drying in storage.

10. treat that brick tea is aged in storehouse and reach factory calibration, can pack through inspection party and dispatch from the factory.

After measured, in final Fu-brick tea product Eurotium cristatum number (being commonly called as " JINHUA ") up to 3.1 × 10⁶Individual, far above national standard (GBT 9833.3-2013), and JINHUA granule is big, and naked eyes can observe directly obvious JINHUA granule, grows dim universal, luxuriant, uniform；Soup color glow, fragrance is pure, flavour spy's Fu alcohol and, general Fu is pure；And production cycle relatively conventional production methods has substantially shortening.
