The invention relates to a low-temperature withering device for tea leaves, which mainly comprises a shell, a CPU (central processing unit) control system, a compressor, a capillary tube, a condenser, a radiator, electron temperature probes and a fan. The shell of the whole withering device is of a cabinet type structure; 4-6 layers of interlayers are arranged at the upper part of the shell and are used for placing the tea leaves; the electron temperature probes are uniformly arranged on the interlayers and are used for detecting the temperature of each interlayer; the compressor, the capillary tube, the condenser, the radiator and the fan are arranged at the lower part of the shell; the condenser is positioned above the radiator; the capillary tube is positioned between the condenser and the radiator; and the temperature in the whole withering device is controlled at 8 DEG C. According to the low-temperature withering device provided by the invention, the time for the tea leaves to wither is greatly shortened, the efficiency for making tea is improved, the risk of nonuniform quality of high-end brand-name tea is reduced, the quality of the tea leaves is improved, and the competition of the tea leaves in the market is enhanced.

The invention relates to a tea leaf firing machine, and in particular relates to an automatic discharger of a tea leaf firing machine. The automatic discharger comprises a stand, a tea leaf firing pot and a vibrative conveying slot, wherein the edge of the tea leaf firing pot is connected with the stand along the middle part of the tea leaf firing pot through a hinge, the hinge is fixed at the middle part of a cross beam at the upper part of the stand, the vibrative conveying slot is arranged in the stand below the tea leaf firing pot, the automatic discharger of the tea leaf firing machine further comprises an electric push rod, one end of the electric push rod is hinged with the middle-upper part of the edge of the tea leaf firing pot, the other end of the electric pushing rod is hingedwith the stand, and the automatic discharger further comprises an electric heater and a temperature controller, and the electric heater is fixed on one side of the middle part of the outer surface ofthe bottom of the tea leaf firing pot. The automatic discharger disclosed by the invention is additionally provided the electric push rod and the electric heater so as to be capable of automatically discharging materials without troubles of manually charging materials, largely improve tea leaf making efficiency and be clearer and more environmental-friendly.

The invention relates to a method for low-temperature withering tea leaves, which adopts a refrigeration technique, a condenser is installed in a withering chamber, an inverter compressor is utilized for refrigeration, an international environmental protection R410 refrigerant is adopted, a fan is used to blow the cold air uniformly to the surfaces of the tea leaves, so the water of the tea leaves is quickly volatilized, and the tea leaves are softened; the withering chamber takes a standard that equipment with the refrigerating capacity of 2500 watts is configured every 25 cubic meters; and the temperature of the withering chamber is controlled between 4 DEG C and 12 DEG C. By the method, the withering time of the tea leaves can be shortened, the tea making efficiency is increased, moreover, the tea quality is also greatly improved, and the market competitiveness of the tea is enhanced.

The invention relates to a tea leaf fixation method. The tea leaf fixation method comprises the following steps of: (1) collecting fresh tea leaves in the same day and piling up in a centralized manner; (2) starting a tea fixation machine and keeping the fixation temperature between 250 DEG C and 280 DEG C; (3) evenly feeding fresh tea leaves into the tea fixation machine, and performing fixation for 4 minutes + / - 20 seconds; and (4) performing chilling and cooling on the tea leaves conveyed from the tea fixation machine, so as to ensure no yellowing and deterioration caused by piling up. As the traditional wilting process is removed, the tea making efficiency is greatly improved, the risk that the quality of famous high-end tea is not uniform is reduced and the market competitiveness of the tea leaves is enhanced.

The invention discloses a carburizing and quenching large internal tooth ring gear processing method, which comprises the steps of removing machining stress, semi-finishing, milling, carburizing, induction hardening, finishing and grinding in sequence after tooth opening is completed. Among them, carburizing is carried out according to the set depth of hardened layer; induction hardening adopts profiling method for tooth-by-tooth induction hardening; finishing car adopts vertical lathe clamping and processing including the processing content of grinding gear clamping benchmark; The alignment process includes preliminary alignment and precise alignment. Preliminary alignment is carried out according to the alignment gear center and leveling end face, and the gear deformation data is obtained by detecting the gear pitch circle runout values ​​of multiple sections in the tooth width direction; the precise alignment is based on the obtained The gear deformation data is corrected according to the principle of uniform distribution of the grinding allowance; the finished product is obtained by grinding the tooth surface. The beneficial effect of the invention is that the gear can be made of low-carbon alloy steel, has long service life, low energy consumption, low processing cost and high production efficiency.

The invention provides a kang tea, a preparation method thereof, and a pottery pot for preparing the kang tea. The preparation method of kang tea is as follows: heating the tea making pot to 70-150°C; putting raw tea leaves into the heated tea making pot, stirring and kneading at 70-150°C to obtain shaped tea leaves; The shaped tea leaves are baked until the color is light yellow to obtain a product. A pottery pot for preparing kang tea comprises: a pottery pot body; a pot handle arranged on the outside of the pottery pot body; a kneading device fixed on the inner wall of the pottory pot body, and the kneading device consists of a plurality of protruding The ribs are composed of a plurality of ribs distributed radially. The process of the method of the present invention is simple and suitable for industrialized production. The prepared kang tea has the characteristics of rich and unique fragrance, golden and bright color after brewing, strong and sweet taste, etc.; There are three steps of roasting, and you can also brew Kang tea.
